You’re more likely to respond to such a survey if your battery fails. This survey is suspect at best!

Hi Sean. I like the effort, and contributed to your data points as one of the “failures”. However, there are some scientific gaps in the methodology and reporting. As others have mentioned, sample size is too low and owners with failures may be more likely to respond (like me). Further, the total number of cars on the road (and cumulative miles driven) vary greatly between models. I recommend attempting to normalize the data to glean more meaningful results. Also, I’d love to see data on how much people paid to have their batteries repaired or replaced. For me it was $0, covered under warranty at 80, 000 miles. My car is almost to 140, 000 miles now and the replacement battery is holding up well. Cheers!

I wonder if owners with battery failures are more likely to fill out a survey? 7% seems super high.

[truesimplicity]

The sample pool is too small to be relevant with the millions of Tesla's out there...

A better metric would be battery failures per miles driven.

I had a (very short) conversation with someone whose “sister’s girlfriend” or “girlfriend’s sister” had to spend 23, 000 replacing her Tesla Battery Pack. When I asked “how old was the car.?” Answer: 4 years. So I called “Bullshit”, mentioning that the warrantee was 8 years. . . That’s why the conversation was short.

I wish Tesla would publish their stats on battery and motor failures in the spirit of transparency to built brand credit and trust.

240.000 miles. 7 years old 85D. Still on the original battery and dual motors.

We have about 32, 500miles on our Model Y long range AWD and our range is currently at 298miles. This is about what I expected for range reduction when we bought the car in July of 2020. Still look for excuses to drive it. Love this car.

Feedback: I have 10x Teslas of all sorts in my company since 2019. out of those only one Model X with 95.000km had an issue. Tesla SeC gave me a complete new Batt, instead of a refurbed one, which was cool. It took them almost 3 months which wasn’t cool.

What was the selection process for members of the sample? If just voluntary, then any who had a failure are FAR more likely to respond, making your result completely meaningless.

If that is not fixed, you must be catagorized as a FUD source.

Compared to the GM Bolt...
7% failure rate is something they aim for by 2045....

[daemenoth]

This is way to small of a sample size to gather any conclusive data. It also is worth pointing out that people who experience issues are far more likely to go out of their way to make not of it. You also don't specify the details on what you consider to be a battery failure, is it referring to a battery that falls below 85% of its original capacity? There is also no consideration for the amount of the included vehicles with that specific battery configuration in circulation.

[aldimore]

I think your sample size is way too small. Likely those that have a battery issues are more likely to be online searching, vs non failed cars and owners just living life and not looking for surveys to fill out.

I would like to see a category on what mix of supercharging and low voltage charging was done per survey.

[inqonthat]

I'm looking at used Tesla Model S's. On dealer lots, is there some way of determining if the original battery has been replaced? Say... by a dated sticker on the battery or by menus giving a newer date or lower miles than the car's date or miles?

[YouTube_username.]

It would be a mess to get into it but i'd be interested in a breakdown of the failures by year/major design iteration. eg 70D and 100D in same gen vs 60/85 older gen

[djfrankib]

The bottom line is no Tesla model is a car you can keep reliably after the warranty. What I mean is inevitably you will need a battery; probably sooner than an ice car needs a motor. Probably something like a Lexus. Charge cycles only last for a specific amount of time.

[sohaibyounus]

A good time to do an update on this, been seeing some failures for out of warranty customers since there are a lot more used Tesla’s in the market.

[Toycollector]

As so many others have noted the sampling is not random so the data isn't really very useful. I did fill out your survey though. Would be more interested to know the percentage of failures based on the percentage of respondents. In other words, if 30% of your responses were long range model Ys, were 30% of the failures long range model Ys?

I live about a mile from a Tesla service center, when I pull in to use the supercharger about twice a week I enter from the back and pass by the dumpster. I’m always surprised how often I see an empty wooden box that is shaped like a battery. To me that 7% might be right.
