In what world is this "The 2026 TUV Report doesn't mention which defects were responsible for the Model Y's disappointing performance." acceptable?

Why are they not publishing which defects exist? Not only it make more credible, it would also warn people of what to look for.

[elaus]

TÜV is the mandatory inspection that every car in Germany has to go through. Failing that inspection means you _have_ to fix the issues or may no longer drive that car on public roads.

So while it would be nice to get more detailled stats, I think this is still really helpful. For me the TÜV report was a very important source for my decission on which models (and to a lesser degree manufacturers) I should avoid.

[kiney]

There are more accredited inspection providers besides TüV in germany like Dekra etc. This matters because TüV does NOT have data for all cars and there might be self selection effects because drivers can choose where to do the inspection (many get it done by whatever provider their car dealer has a deal with, which might differ greatly by car brand)

[thyristan]

TÜV is the largest such organisation in Germany and almost has a monopoly. The inspections themselves are colloquially even called "TÜV", even if you do it at some other org.

However, as others have written, there is still some huge bias in those numbers. Especially German brand car shops provide an inspection service, where they pre-check and repair the car before the official inspection. Many of those German brands are also very big on company leasing, to the point where almost nobody buys a new BMW, Mercedes or Audi privately, they either get a new one as a company car via company leasing, or they get a used leasing return car. All those leasing cars always have the aforementioned inspection service as part of the leasing package. So those numbers are to be taken with a huge huge grain of salt.

[kiney]

First of all TÜV isn't a single org but a shared brand of multiple independent companies. And while "TÜV" is used colloquially for the mandatory car inspection in germany even all TÜV named companies together aren't anywhere near a monopoly: all of them combined(!) have 37,5% market share in the german vehicle inspection market. The largest single org in that market is actually DEKRA with 32,5%.

People say "Ich bring mein Auto zum TÜV", but they actually mean "I'm gonna drop it at my dealership and let him inspect it by whatever company he has a deal with"

Typically Teslas have failed for suspension issues in Finnish inspections. Most common failure category for Model 3 was "rear axle" and "front axle" for Model S.

This is an article that summarizes a report. It is not the report. The actual report costs money (but isn't very expensive).

If you live in Europe your car has to be inspected every 2 years. For new cars this kicks in after 3 years, and then after that it is every 2 years.

The inspection is carried out by authorized mechanics and typically takes less than an hour. It is worth noting that authorities keep a close eye on authorized mechanics to ensure they do not cheat. If you cheat (eg let people pay you to pass their car), you lose authorization.

The reason the TÜV report carries weight is that Germany has Europe’s largest vehicle fleet and TÜV has a strong reputation. Inspection standards are largely harmonized across Europe, and approvals or methodologies used by TÜV are often accepted or mirrored elsewhere.

Defects are classified by severity. Serious defects can make the vehicle unroadworthy immediately; less serious ones require repair and re-inspection; very minor issues are simply noted.

Even non-EU countries like Norway and the UK follow essentially the same inspection framework.

Does this put Germany's car insurance in the lowest cost?

[thyristan]

Car insurance in Germany exists in 3 categories.

The mandatory one, liability insurance, which pays out others' damages in case your car is in an accident and the driver of your car is found to be at fault. Base rates for those are by law based on the rate of payouts per car model and per owner's county at that insurance company. A multiplier makes the base rate more expensive or cheaper respectively for new drivers, accident-prone drivers or long-time accident-free drivers. No other external statistics are allowed to play a role.

The two non-mandatory ones are "Vollkasko" and "Teilkasko", which pay for damages your own car suffered from various factors like animals, weather, accidents, road conditions and stuff like that. Vollkasko even pays for accidents you caused yourself, Teilkasko only for some of the aforementioned things. In both, insurers are still required to do some classification by county, but they are allowed to factor in statistics about your car's repair cost.

But none of those will pay for your car just randomly breaking down and needing repairs, that is something you get a manufacturer's warranty for. And none of those is directly related to the mandatory inspections. I think I've read some statistics that driver behaviour and skill is also a large factor in why there are less accidents in Germany, at least compared to some regions of the world... But make of those what you will, that might as well be jingoism and often also comparing apples and oranges...

[sandos]

In Sweden some of faults can be covered if the mileage is low enough, usually the limit is between 120000 and 200000 km. Usually engine and tranmission is covered.

[bborud]

On average car insurance is cheaper in Germany, but I am unsure if this has anything to do with the required inspections. (Since it is mandatory anyway, it isn't a differentiator). I think it may be more about how insurance is structured and dealt with.

For instance US has a civil tort based system which tends to push prices up quite a bit because outcomes are entirely unpredictable. In Germany insurance is not litigation centric, so there are literally no punitive damages, pain-and-suffering awards are modest and predictable and compensation is based on standardized tables. So insurance cases very rarely make it anywhere near courts.

[josefx]

They are citing a blog post from the German magazine Auto Bild, which talks about the Auto Bild special "TÜV Report" edition. They are probably three or four layers of indirection removed from the original report produced by the TÜV itself.

I found a mention of the report on this page from the ADAC: https://www.adac.de/news/tuev-report-2026/

I think they mention suspension, brake and light related issues.

[kotaKat]

“The Tesla 3 and Y are not so fortunate, landing in second to last and last place respectively due to faults in their brake disks and axle suspension.”

https://www.tuvsud.com/en/newsroom/press-releases/2025/novem...

Just… I don’t know, actually look at your wheels and brakes every few thousand miles instead of let them ride for tens of thousands without service? Shouldn’t people be rotating their tires every 3-5000 miles anyways?

[otherme123]

Tires are not mentioned here. You could rotate them every 10 miles and still have faulty brake disks and axle suspensions.

- Brake disks are not a regular maintenance piece. Brake pads are the pieces that need replacement every 30.000 kilometers, depending on how hard you use them. But brake disks can outlast the car.

- Axle suspension is also not regular maintenance piece. Damper, bushings and springs need supervision and get changed every 80.000 kilometers or so. But to change an axle suspension without a serious hit to the car is very weird.

Unless you are using brake disks and an axle suspension designed for a 1,000 kg lighter car. In that case, you might end with twisted or broken pieces after a few thousand kilometers.

[loloquwowndueo]

What if the fault results in a failure after 800 miles? How does checking every few thousand help there?

[troupo]

> I don’t know, actually look at your wheels and brakes every few thousand miles instead of let them ride for tens of thousands without service?

Let's read the text further and see the description for the winner, Mazda 2, emphasis mine

--- start quote ---

Mazda 2. Only 2.9 percent of these French-manufactured Japanese hybrid compacts turn up at their first periodic technical inspection with significant faults at an average mileage of 29,000 kilometers.

--- end quote ---

And then:

--- start quote ---

At the bottom of the table, the Tesla Model Y took over in last place from the Tesla Model 3 (17.3 percent). Second to bottom was the Ford Mondeo (14.3 percent), while the third from bottom was the Tesla Model 3 at 13.1 percent.

--- end quote ---

So, at regular inspection intervals (as proscribed by manufacturers and regulators) Teslas show significant faults.

[haspok]

But hey, these are electric cars which don't need regular service!...

...at least that is how they are sold. And people take it seriously.

[orwin]

They cost less to service on average, which is true (at least in my country, Americans are weird with their cars and dealerships).

[ActorNightly]

Do you really need any more reasons not to buy a Tesla?
