A word on Tesla

I don't approve of Elon Musk's behavior, and I wish he'd disassociate himself from Tesla so they can continue doing business without the stigma of his actions hanging over them. A lot of people, myself and my family included, bought Tesla vehicles before all of this started. Tesla already has that money, so selling the vehicles at a thousands-of-dollars-loss makes no difference to them, but it's a significant amount of money to us. As long as Elon Musk is still associated with Tesla, a lot of people are going to avoid the brand, or move away from it if they were already customers, and that's really unfortunate because the vehicles provide a LOT for the money. Based on my experience, and comparing range, performance, and technology, I just don't think there's anything else that competes today.

The Accident

The big news of the year was being nearly T-boned by a red-light runner (thanks, Central City Concern driver) and having my car undrivable for 4 months out of the year (and as of this writing, still going). Fortunately, no one was injured in the accident, but the other driver's decision to blatantly run a red light caused thousands of dollars of damage to both vehicles and so many hours of my time that I've stopped keeping track. If my car had been 1 second further into the intersection, they would have directly hit my passenger, likely with significant if not tragic effect.

I'll get into the details of each but the key takeaways from that experience are:

Tesla's Vehicle Data Recorder

I knew Tesla recorded data about the vehicle but I was really impressed by seeing all the data and how clearly it's presented in the Vehicle Data Report. I don't recall the exact steps I went through to request it, but this blog describes a process that is likely accurate. Not only does the report include timestamped and encoded video, but it also includes graphs of things like speed, accelerator and brake pedal position, steering angle, etc. AND for those interested in data, it provides millisecond timestamped logs in the form of a CSV with sensor values and states. I'm not sure any other manufacturer provides this level of detail, but it would be great to see this standardized and become a common feature on all vehicles. Human memory is fallible and having data tell the story of an accident instead just seems so much better.

Getting a Tesla repaired

I think a lot of people would be quick to blame Tesla or electric vehicles for how expensive and how long it's taken to get it repaired, but I don't think either of those are true. I think the cause is more likely that the popularity of Tesla vehicles (prior to recent events) shot up more quickly than the infrastructure for repair could keep up, both in terms of number of authorized repair shops and parts supply chain. Certainly I could have taken the car to a non-authorized repair shop but given that it's still under warranty, I wanted to do everything I could to stay within the terms, and I figure an authorized repair shop is more likely to do so (or present less opportunities for debating it later).

The process involving Tesla was kind of interesting - when I submitted a ticket through the app, it had me upload photos of the damage, which it analyzed and determined immediately that the repairs were significant enough that the Tesla Service Center couldn't perform the repair and that it would need to go to an authorized repair shop, which it provided me a list of. That's pretty cool, I didn't have to book an appointment and take it in just for them to tell me that, like I would expect to happen with my previous cars.

Working through the other party's insurance and the actual authorized repair shop has been less streamlined but easier than I expected. Unfortunately, for various reasons, the entire process has dragged on - I'm almost 5 months since the accident, and the car still isn't done (but it only went in a month ago due to how busy they were, and it's been waiting for parts arrival for most of that). The current estimate is around $21,000 for what seems like a relatively minor repair, but I think the reality is, even though it appears minor at first, there were actually quite a number of body panels and components that were damaged, including parts under the body work not immediately visible from outside.

Other EVs in comparison

During this whole thing I've had 4 other EVs as rental cars so I've gotten a chance to compare them to my car, and with maybe one exception, I wouldn't trade my car for any of them.

Charging

The charging graphs do show a considerable reduction in time spent at home charging when I installed the L2 (30A@240V) charger, and then of course when the accident happened:

The breakdown of charging costs and kWh per source are pretty similar, with a slight skew more toward home charging (I spent less time on the road in the last year).

Range Loss

Range loss appears to have leveled out a bit, but I suspect the variation is more in changes to charging habits (I now charge mostly only as I need it, rather than constantly keeping it topped up to 80%) and the impact that has on BMS range estimates. For point in time:

Note that is total loss, not loss-per-year - and in year 2 is when I stopped keeping it topped up to 80% all the time, so I expect it to be more accurate from there. The general wisdom remains that most loss happens in the first year and then slows down, so I wouldn't be surprised if I lost 3% in the first year, 1.5% in the second year, and 1.5% in the third year for a total of 6%. If I continue that 1.5% loss per year for 10 years, I should still be at >300 miles of range at 100% charge, which I think is still more than any of the rental EVs I've had when new.

Conclusion

It's a bummer that the car has been inoperable for 1/3rd of the last year, but it's been an interesting experience getting to try out other EVs for long periods (most of them 1 month at a time). It's reinforced for me that the Model 3 was the right choice back in 2022. If my car were to be totaled as a result of the accident, I think the Rivian would be the top contender, but the high price tag is pretty hard to swallow. I think this is where I start considering leasing vehicles instead of buying them. Depreciation on the Model 3 is optimistically looking like ~$650/mo, and more realistically, it may actually be closer to ~$850/mo. A couple weeks ago, a 2025 Rivian R1S Dual Standard in Blue was $832/mo with $0 down payment (prices has since gone up, though). I suspect the depreciation curve isn't linear though, so it's not like I'll continue to lose $850/mo by keeping my car, but I think in the future I will much more seriously consider leasing. You may not have anything at the end of the lease, but nothing is better than a negative balance.

Year 2

Total Stats (2022-03-23 to 2024-03-23):

Charging

The charging graphs don’t look too different this year, I spent less time charging at home due to being on the road more:

And that’s reflected in more costs and kWh being from Supercharging than home or other:

Range Loss

Starting Range at 80% charge: 286mi Current Range at 80% charge: 278mi Estimated Lost Range: 8mi or 3%

This is actually better than at the Year 1 mark - I’m currently at 79% with an estimated 275mi of range, which extrapolated to 80% would put me at 278mi of range. This time last year, it was showing around 268mi of range at 80%. I attribute this to a change in charging style for the majority of Year 2, where rather than constantly plugging in at home and charging to 80%, I would only charge when the car got below 50% or so. This gives the car a chance to sleep for long enough that it opens the contactors and the BMS can get good readings on Open Circuit Voltage.

Of course, actual range varies, but this is the closest “easy” way I have of gauging range loss due to calendar aging.

Home Charging Upgrade

For all of Year 1 and for 11/12 months of Year 2, I only used L1 charging at home, and it was totally sufficient. In fact, it was sort of a point of pride - I owned an EV and didn’t have to do any special electrical work at home to make home charging work! And I could have continued that way, except while traveling a lot to my girlfriend’s parents’ house this winter, I found two things:

We weren’t staying at my girlfriend’s parents’ house since it was under construction, and I didn’t feel comfortable (or couldn’t access an outdoor outlet) with charging at the Airbnbs, so I’d charge when we went over to the construction site to work. Unfortunately, with the cold weather, that meant the car took extra long and so I had to spread out charging over a few days, and it was kind of a pain to leave it there overnight. On top of that, my car would be in the way of construction vehicles or deliveries, so I had to be around to move it. But then we discovered that they had a 14-50 outlet near their driveway (RV hookup?) and it made things so much easier that when we got home, I decided to upgrade my home charging too.

Due to my sub-panel size and the cost of copper wire, I decided to opt for a 14-30 rather than a 14-50. The 14-30 got me a 4x increase in charging speed, while the 14-50 would have gotten me a 6-7x upgrade. I decided that the 14-30 was a good balance of fast, cheap, and easy - and going to a 14-50 would have been both considerably more expensive and more work. Regrettably, I didn’t take advantage of PGE’s really good $500 charger rebate before they reduced it to $300, as that probably would have made the extra work worth it to go with a 60A breaker and wiring to install a dedicated L2 charger.

In any case, I’m happy with the speed of the 14-30. Since upgrading to it, I’ve averaged 1.6 hours per day of charging on the days that I do charge, and 36 minutes per day overall. And I should be able to charge 20-80% every night if I ever take on some crazy commute schedule.

Different Driving in Year 2

This year was a lot more highway miles than last year, as I was making regular trips back and forth between Portland and my girlfriend’s parents’ house in Northern California (a little over 1000 miles roundtrip). That means more money spent at Superchargers, which is about 2.25x the rate per kWh as I pay at home. I would have expected to have worse efficiency due to highway speeds and cold weather driving, but at 297Wh/mi I’m doing better than last year’s 306Wh/mi. Maybe the difference is attributable to those early ownership hard accelerations.

Northern California in the winter means potentially driving in snow, or at least below freezing conditions, so I picked up some Nokian Hakkapeliitta R5EV snow tires and have been very happy with them. I’m planning to order another All Season Wheel and Tire package from Tesla to get another set of the 18” Aero wheels, though I’m not thrilled about the stock tires they come with (more below).

I mentioned a little before that cold weather charging is slower - I didn’t pay close attention to it, but I did notice that when I was plugged in at L1 and it was ~20’F, it took longer than I expected to charge up. It wasn’t impossible, I was still able to charge all I needed for the driving I was doing, but discovering I could charge at L2 at their house definitely made things more convenient. I would recommend any Tesla owner buy at least a 14-30 adapter for your mobile charger - I also have a 14-50 and TT30, and these are nice options to have for RV parks or Airbnbs when traveling.

The other thing worth talking about with cold weather is efficiency, but honestly, I didn’t pay much attention to it. I made the same drive through mountainous roads with snow, ice, and dry pavement probably 4 times and I didn’t notice a significant difference in arrival state of charge when I got to each Supercharger on the way. There probably was a few percentage difference, but I was never at risk of not making it to my next stop.

Rural Charging

It’s really not that bad, DC fast chargers are needed for road trips, but if you’re just staying in a rural area, L1 will do fine a lot of the time, and there may be L2 chargers if you really need it (town halls, city parks, or RV parks). PlugShare is a good app to have to find these, but I didn’t need it at all during my time in rural Northern California. At most, you may need to plan a little more, and make sure you’re plugging in as much as possible if you have to drive 60 miles to a store on a regular basis.

Tesla Specific Things

Probably the biggest annoyance I had to deal with this last year was the foam detaching from the inside of the stock Michelin Primacy MXM4 tires. This caused a vibration from 55-70mph, and despite taking it to 2 shops, 4 different times, no one was able to identify and fix the issue until I had researched it and suggested they look for this specifically. This cost about $300 to have a shop remove, which did fix the vibration, but then I also replaced the tires entirely about a month later when I switched to snow tires. The Michelins were worn enough that they weren’t worth keeping, but in retrospect, I probably should have just gotten the snow tires sooner and saved myself the $300.

I had a few more Service Center visits - two TPMS sensors stopped responding (battery probably) and needed to be replaced under warranty, and my car was broken into in Oakland, CA when we were visiting, and I had to get the rear quarter window replaced, fortunately covered by insurance.

I’m not sure there have been a ton of significant upgrades through Over The Air updates this year - they added a blind spot “highlight” to the blinker cameras, which is a nice addition, but nothing else feels as significant as the ability to reposition those blinker cameras on the screen. Well, I guess they did introduce 1-pull to enable AutoPilot (which means you can’t enable just Traffic Aware Cruise Control anymore, if you turn on this function). I do feel this is a nice change, and I haven’t found myself wanting TACC-only since switching it on, but it’s also pretty minor.

Surprisingly, I have been following the Full Self Driving Beta version 12 results and I’m kind of tempted to try it out (via the monthly subscription) once it goes wide-release. It’s looking pretty promising and has corrected a lot of the issues in version 11, though it’s still definitely not where I had thought it was prior to buying the car.

Conclusion

I don’t have as much to say after year 2 compared to year 1, but I am still very happy with the car, and with owning an EV. I hope the DC fast charger infrastructure continues to improve, and non-Tesla EV owners get to start enjoying the convenience of the Tesla Supercharger network. I’m still a long way from considering replacing the Model 3 with something else, but I will say the Rivian R2 looks pretty tempting…


Year 1

1-Year Stats (2022-03-23 to 2023-03-23):

TL;DR, things learned:

Time Spent Charging at home:


Average of 5kWh and 4 hours per day with Level 1 charging, 12A @ 120V (1.44kW)
Cost: ~$0.13 per kWh or ~$0.68/day

I’ve tracked this closely to decide whether or not it would be worth it to upgrade to a Level 2 charger at home - my initial assumption is I’d have to do this, but after a year, the data shows that this is completely unnecessary given my usage. For how little I drive day-to-day, my Level 1 home charger (which came with the car at the time) is more than sufficient.

Upgrading to a Level 2 charger would cost, at minimum, $200 (with utility EVSE discount), assuming I do all the work myself, and can reuse the A/C circuit from the garage subpanel, which would be less-than-ideal. More realistically, it would probably be closer to ~$1000 for a dedicated circuit, possibly ran from the main panel. However, there’s just not sufficient benefit to justify that - I can think of one, maybe two times in the last year that I would have benefited from the L2 charger: once when we were doing a lot of driving one weekend, and once when my family was visiting and also rented a Model 3. In both of those cases, a $10-$20 DC faster charger stop would have helped with the anxiety, but neither ended up being an actual problem.

Overall average miles driven (with roadtrips): 29.54 per day

Time Spent Charging on the road:

I haven’t tracked the time here as closely, so this is more anecdotal. The vast majority of my charging on the road (due to road trips), has been on the Tesla Supercharger network, but I’ve had a handful of L2 charging at RV sites and hotels (with 14-50 or TT30 adapters), and purchased the CCS1 adapter for use at non-Supercharger DC fast charging stations, and have used those a handful of times as well.

To make a broad statement: I don’t spend a lot of time waiting around for the charging to finish.

Early on, I think I tended to charge the way one would fill-up a gas tank: run it low, then charge back up to full. The generally accepted wisdom these days is to make “frequent short stops” not “infrequent long stops”. I.e. charge 4x at 15 mins each, rather than 2x at 40 mins each (charge rate is nonlinear, so it takes longer to go 80->90% than it does to go 50->60%).

Supercharging has consumed the majority of cost, but isn’t the majority of charging, it’s just expensive.

Range Loss

I normally set my maximum charge to 80%, as that supposedly extends the life of the battery. Since getting the car, I’ve recorded the estimated range when charged to 80% each 1st-of-the-month. About 6 months in, it began stopping at 79% charge, though I suspect this is a display issue (it can certainly charge above 80% if I set it to do so, and I suspect if I set the max to 81%, it would stop at 80%).

The purpose of this is to try to estimate how much range (or total capacity) has been lost since getting the vehicle:

Spurious reports from the internet suggest the range loss curve is steeper at the beginning of ownership, and levels out over time.

This post on Tesla Motors Club also suggests some of the loss may be due to the Battery Management System (BMS) being unable to correctly estimate range because of charge conditions - which is plausible with how I use the car: it may not be getting many opportunities to take Open Circuit Voltage (OCV) readings at various states of charge (SOCs) in order to calibrate the range estimate. Going forward in year 2 of ownership, I’m planning to not leave the car plugged in at home as much, so it’ll get to take OCV ratings at more various SOCs.

That all said: I’m not worried! I haven’t been stranded yet, or even come close, and the ~335 miles or range I’m estimated to have at 100% SOC is more than enough to get me between chargers (DCFC, L2, or even L1 if I’m patient).

Purchasing Decision Priorities

An EV (or at least, a plug-in hybrid) was on my list of things to buy for several years. Probably at least 2, possibly 3 years. During that time, I made several lists, watched lots of videos, did lots of comparisons, and narrowed my picks to 3 cars, in chronological order:

The V60 remained at the top for a long time, and if it had the Polestar 2 drivetrain, it probably would have won out (I just don’t love the looks of the Polestar 2, the V60 wagon is way cooler). But I wanted a full EV, not just a plug-in hybrid.

When the EV6 was announced, I put in a pre-order for it, and was eagerly awaiting it. Unfortunately, Kia really botched the lead-up to their US rollout. The specs kept changing constantly on the website, and it wasn’t clear until much later what range, horsepower, or features would be coming to the US, so eventually I canceled my pre-order and ordered a Tesla Model 3.

But before pulling the trigger, I listed out some priorities and assigned scores to the Model 3 and the EV6, to see if that was the right choice.

Have the Priorities I defined held true? I.e. have the things that were priorities for the Tesla actually been used as much as they were estimated to?

Range

- At the time, the Model 3 beat out the EV6 with 358 miles to 310 miles. That would mean the EV6 would hit 0% when the Model 3 would have 13-14%. This was one of my top priorities, but looking back on it, I’ve rarely, if ever, gone below 13% range remaining on the Model 3. So the EV6 range would have been sufficient for me.

Horsepower

- The Model 3 LR is estimated to have 346HP to the EV6’s 225HP. This wasn’t necessarily a priority, but I’d be lying if I said I didn’t consider it. Ultimately, though, this would have zero impact on my actual use.

Charger Network

- This was one of the top priorities for me, access to the Tesla Supercharger network, which is known to be reliable and relatively dense. I would say I haven’t used it as frequently as I thought I might, but it has been very, very nice to have on road trips. That said, I expect in the future, the value of this will go down: Tesla is opening up their Supercharger network to non-Tesla EVs, and non-Tesla DC fast charger networks are bound to improve with the Bipartisan Infrastructure Law. However, for the last year, it has definitely met my expectations.

Frequent Software dev, OTAs

- Probably the top differentiator for Tesla vs other brands is the frequent software development and Over-The-Air updates, and I do feel that the car/brand has lived up to that expectation. In the last year, several minor quality-of-life changes were made: the ability to reposition the indicator camera view, adding shortcuts to the bottom bar, adding 2 levels to the heated steering wheel, and adding green light change notification. But probably biggest of all was the change to automatically engage the brakes when regenerative braking isn't available. Prior to this update, if the car was a high state of charge, or in cold temperatures, you'd have limited regenerative braking, and getting off the accelerator wouldn't slow the car as much as normal, which was a super unexpected thing to encounter the one time it happened to me. Fortunately, that's now fixed, and just via an OTA software update. Whether Kia would provide similar regular OTA updates was a complete unknown for me when making the decision, and I’m still not sure to what extent they’re pushing changes on the EV6.

App

- I expected that the Tesla app would be more solid and quality than other brands’ apps, as it’s had a longer development history, and though I haven’t tried others, I expect that is probably true. The two complaints I do have about the app are latency issues and command status ambiguity. If the car is asleep (typically at home), it takes probably 20-30s for it to wake up before you can issue a command like turn on the climate control. Other commands like opening the frunk/trunk are instant. The second issue is related - if the car isn’t awake yet or has poor cellular connectivity and you issue a command, it’s not always clear whether that command has been sent, received, or has taken effect. Technically, if you use the app a lot you can notice the minor changes that indicate this, but there is room for improvement as well.

Sentry Mode

- As far as I know, Tesla is still one of few manufacturers that offer Sentry Mode (always-on video recording when the car is parked), however, I had expected it would perform differently than it does. It only triggers a notification to the app when the alarm is tripped, not when Sentry Mode is triggered. So for example, if a window were broken it might send a notification, but it won’t if someone tries the door handle. While that was different than my expectation, it’s probably for the best because of the second issue: false positives. I most commonly see this with rain drops when the car’s sitting outside. It’s probably some combination of rain and light causing the object recognition system to think it sees a person close by, but on a rainy night you can sometimes have 20+ triggers. If someone also keyed your car on that same night, good luck sorting through the false positives to find that. This leads me to ignoring Sentry Mode notifications that pop up on the main screen most of the time. Also, the camera quality is poor so you’re unlikely to get a good face capture or license plate out of it. That all said: since most manufacturers don’t have this feature at all, it’s better than nothing.

Build Quality

- I went into it expecting that build quality / quality control were going to be poor, and I would say my expectations have either been met or exceeded. The car had two minor “issues” when I picked it up: two error messages that required shop time, first a delay in picking the car up, then having to schedule a return visit to get a cable properly seated. But worst, the car had some minor scratches in places when I took delivery, and those wouldn’t be fixed with a few hours at the service center. The driver’s side door near the handle is probably the most noticeable, like someone was getting into the vehicle repeatedly while wearing a watch that scratched the paint each time. There’s also a rattle on the driver’s side B pillar that could probably be fixed with some adhesive if I wanted to disassemble it. And the car makes a grinding sound at low speed (<20mph) that I took it to the service center for and no change was made, but it doesn’t appear to be an issue so I haven’t revisited it. But I went into it expecting minor issues and minor issues is what I got, there haven’t been any major problems making me regret the purchase.

There were two things that I didn’t put on the comparison list when I was making my decision, but they were in the back of my mind:

TACC/AP/FSD

- Also known as: Traffic Aware Cruise Control, Autopilot, and Full Self Driving. These have been a big let down, even though I went into buying the car expecting that they wouldn’t be perfect. The biggest issue is the Traffic Aware Cruise Control, which has had enough unexpected braking events to harm my confidence in it. I have narrowed down one of the cases where it happens, and now make sure to avoid using it in those situations: when approaching a hill with no visibility over it, and no lead car to follow. However, I had one instance of it occur with a vehicle merging onto the freeway but with at least one extra lane between me and them. This has only happened once, but combined with the hill issues, I’ve come to not trust TACC as much as I would normal cruise control, and I end up not using it as much as I would like to. Autopilot, or more accurately, lane-keep assist, is fine on highways except when lanes merge, and it sees one giant lane and tries to center itself, causing the car to steer back and forth unnecessarily. This has also reduced how much I use it, basically only to instances where I can be in the center lane away from merges or where there won’t be a merge for a long time. I did not purchase Full Self Driving but I have been following its development since I got the car and I’m both disappointed in where it was then and how little it’s progressed since. When I first rented some Teslas, they had FSD (not beta) and I expected it to be much better than it was. That was admittedly foolish on my part, and my opinion has definitely changed from “It’s right around the corner and will drive better and safer than I can!” to “I’m not sure that’ll even happen in my lifetime”. I hope Tesla proves me wrong (and that the hardware that came with my car can actually support whatever version they eventually get out to the public).

Vehicle-2-Load/Home/Grid

- I didn’t have this on my list because I assumed every EV was capable of it, only to find out after getting my car that current Teslas aren’t expected to ever be able to do it (supposedly due to hardware in the inverter?). This was a huge let down. Even just having the ability to do a single 120V @ 12A plug like the EV6 would be a big value add, and even better if I could do full home backup like the F-150 Lightning. I really wish I had done my research here before buying.

Conclusion

- Mostly positive. There are a lot of negatives up there, or things that I expected would be a priority for me that ultimately didn’t end up being that big of a deal. However, I don’t really regret purchasing the Model 3 LR. It serves my purposes well and it has some nice benefits that I do really appreciate:

If I could go back to a year ago and do it all again, I think the only place where I’d have pause is if a Ford F-150 Lightning were available for comparable price. Unfortunately, back then (and still to this day?), that’s not the case: the Lightning is super hard to come by and they want like $80K+ for comparable range. Granted, it has features the Model 3 doesn’t: a bed, towing capacity, V2H, and ground clearance, but I’m not sure those are worth $25k+. If I was considering home battery backup, the V2H cost savings, even with bidirectional charging infrastructure, would be worth it, but that’s not a priority at the moment.

I think the next place I’ll be looking for an EV is a Ford eTransit or equivalent, if they can provide range over the current 108 miles. We have ambitions for a van conversion, but 108 miles really isn’t enough to make that a reality on an EV platform. We both kind of feel that if we’re going to spend that much money on something, we’d like it to be an EV, it just seems like the way of the future. Hopefully in the next year or two the range will get high enough to be acceptable.
