Nope, just an outlier

The competence and pricing of dealers along with the proclivities of a car’s customers have a lot to do with it, too. This ranking is basically “of the cars brought for the german federal safety inspection, what percentage were issued a note or failure about an item in a given category” Things like bent suspension linkage caused by driving into a curb, poorly maintained brake pads, or torn rubber boots left unaddress…

They're holding it wrong.

The fact that VW and Mercedes dominated the reliability ratings not Toyota and some other Japanese brand makes me extremely suspicious of this metric.

The metric here is Does the car exhibit problems on an inspection checklist, not is th car reliable. Broken VW are either repaired or scrapped and dont see the light of TUV. VW owners service cars regularly once a year like a clockwork so all the minor ripped rubbers, misaligned headlights, suspension alignment problems, leaking shocks, exhaust leaks, indicator lights etc are routinely tested. Tesla cars dont need _any_ of that. A lot of owners change tires and keep driving until weird smells (cabin filter) or ride harshness (clapped out bushings) starts to really annoy. Its quit common to see Teslas for sale here with untouched suspension and parts grinding metal on metal.

I suspect Toyota might also be a victim of its own reliability. Why would you pay for full service when cars dont break during first 5 years of ownership.

Do regular service intervals influence this? Would Tesla improve the safety of their cars (by this metric) by giving a regular service for safety items in tandem with the safety inspection interval? Damage done by the driver is one thing (AFAIU, Tesla Service pricing is pretty damn competitive for repairs), but warranty work like light alignment and function, premature suspension wear (big on Teslas), and brake maint…

> Do regular service intervals influence this?

Yes but generally in Germany dealer does TUV for you (on newish cars) where they obviously fix issues before actual TUV officer appears and TUV officer are likely to turn blind eye to many issues since they've been going to same dealer for 20 years.

With Tesla first you take to TUV yourself and then go to Tesla to fix them under warranty.

Saying that clearly Tesla's have certain issues and at least we can see them in public. Very disappointing TUV didn't release breakdown of exact problems, by age, region, mileage, etc.

I’m confused from the report about how Volkswagen and Mercedes beat Toyota in reliability when my perception is that it’s not even close. Are the Germans biasing toward their companies? Or am I underrating VW’s quality?

Volkswagens get serviced frequently. Teslas never get serviced, and they don't really use their brakes either due to regenerative braking, so stuff like "rust on brakes" counts as a strike against their "reliability" in this study even though it's harmless. In reality, owning a Tesla is way more painless than owning a VW.

Rust on breaks can be an issue in emergency breaking. Most modern EVs normally use the break intermittently during normal operations to prevent rust from building up over time.

The post doesn't link to the report itself. It looks like you can only read a summary of it for free and must pay 5.90 to download a copy.[1] From what I can glean from reading TUV's summary, it seems like the Teslas had significantly higher mileage than other vehicles (>50,000km in 2-3 years). Also their failures were mostly in brake discs and rear axle issues, which makes me think that due to regenerative braking,…

As a Ford Fusion Hybrid owner I blow out my rear brakes a lot more often out of rust and lack of use due to regen too, so the TUV is just calling out people not getting their vehicles inspected and serviced as regularly as they should.

In other words... Tesla owners just don't pay attention to service intervals as dedicated and surefast as a VW owner would.

Tesla has its problems (between 2019 and 2024 the auto headlights and auto wipers were borderline unusable, now they are merely tolerable, and autopilot is a whole story on it's own), but maintenance is not one of Tesla's issues. Useable, human-readable errors in the app/touch screen (the car self diagnosed it's 12V battery problem and told me to call a tech) and mobile service is just an awesome experience.

Yeah people love to hate on Tesla and always point out the maintenance issues. But from the reports I have seen, Tesla is indeed one of the companies with the worst record in terms of number of incidents requiring maintenance, but among the cheapest, if not the cheapest in cumulative amount spent on maintenance.

I feel like if these report included the price and severity instead of just the frequency of the maintenance it would paint quite a different picture.

Damn competitive? In Europe? Dad's friend is a mechanic and the quotes he's heard of for Tesla repairs are all but preposterous. He's a little biased since he works for a competitor, but also does repairs on the side and Tesla parts alone can be 2/3x other brands. Data size of one, but still…

are you familiar with how statistics and sample sizes work?

I mean this is like comment and comment reply number three of the same pattern: "I have Tesla Model 3|Y and it's doing well" --> "sample size of 1 mreh". Reviews tend to skew negative. Where are all the angry Tesla owners here? (Seriously. I want to hear from angry HN readers about bad 3|Y ownership experience.) I have a Y and an S (Palladium) and the Y is solid (only service for usual EV wear items) but the S has be…

A sample size of 3 happy users, even with review bias, is still way too small to refute a supposed defect rate of 17%.

And I bet that comments on HN are going to be less affected by negative review bias than actual reviews.

Can cobfirm, I’ve been driving a Model 3 for 6ish years and the brakes have problems from disuse pretty regularly. It’s annoying but not critical. Other than that it has been shockingly reliable. This matches my experience.
