Cars: reliability ranking of brands, from 1984 ...

[Obamot]

Fault statistics
With good "visibility" on brands (and models - recently)

Hello,

I found that these stats had their place in a forum such as this one. Indeed, a reliable vehicle will pollute less because it will last longer. This is the conclusion I drew from it, having often driven vehicles "pulling them to the end" for the same reason. Obviously, care must be taken to carry out regulatory services and engine adjustments to reject as little as possible, but in principle all vehicles have been catalyzed since 1997.

Thank you for your feedback and your additions and updates.

Here are breakdown statistics, always done using the same operating method, ie among 1000 best-selling cars (in my area and in Germany => ADAC + TCS).

Carried out by recovery vehicles from the TCS (Touring Club of Switzerland) and / or from the ADAC, in Germany (the first in 1997, only for Switzerland).

1984 [Edit] (from the most reliable or the least reliable
(same for all the following stats)
[Edit]Source: https://www.econologie.com/forums/post147185.html#147185

1997 (breakdown statistics in ‰) sampling: 270 repairs.
Vehicles between 4 and 10 years old.
This study is the most representative, since it was done using TCS data, but by an independent consumer protection program.

Interesting study on "electronic" failures and in particular the "multiplexing" box:

[Edit 01]: update of the title for the year ("from 1984" old. "from 1997") and added a link to your statistical contribution +

Ah thank you, very interesting!

A reliable car is a more eco-friendly car!

I do not congratulate Renault ... but Formula 1 it is true that it is expensive ... to the customer ... I understand!

[Obamot]

Here an interesting stat on the reliability of engines. Interesting in more than one way if you consider that if you want to keep a vehicle for a long time it is an essential organ. In addition, in terms of econology, a vehicle that leaks from everywhere will no longer pass anti-pollution tests, and will contribute to contaminating the groundwater ...

And there ... there is some upheaval in the rankings ...

Once again, the brand that lists the least reliable engines is ... Ren @ ult!

So here is the link (classification still according to ADAC-Germany):

[Christophe]

Small remark on the units: should we not weight this classification in relation to the number of vehicles traveling? Or are the figures given for 1000 identical rolling cars?

Let me explain if there are 10 times more Renault driving than BMW (and in France it is not far from being the case), Renault statistically 10 times more likely to fail ... logical ...

But I assume that it is taken into account?
Because this is not "good" in my opinion:

Number of immobilizing failures per 1.000 vehicles

It should :

Number of immobilizing failures per 1.000 identical vehicles

ps: this topic is timely because I just read an article on the ecological impact of manufacturing a car! I'm putting this on a new topic now!

[aerialcastor]

Then you should especially know the importance of breakdowns, because between changing a hose and a cylinder head gasket there is room ...

[Christophe]

Well I think that these are all the same "heavy" breakdowns since requiring a "towing via tow truck" ...

The fuel shortage is counted in it?

[Alain G]

Obamot Hi!

Your data on the incidence of breakdowns is not distorted by the fact that the purchase of an American car comes with a road service which includes forgetting the keys.

[Alain G]

It includes forgetting the keys:

because it still too often happens that the driver has to call a repairman to recover the ignition key which is locked inside.

http://www.tsr.ch/emissions/abe/archive/99/990309b.html

Chrysler uses Italian or German engines on its European products!

[Obamot]

Wise people like you are, I would say that you have to weigh EVERYTHING, open your eyes and ears wide. These stats give trends ...

But I still took special care in choosing my sources. The TCS in Switzerland was 270 interventions in 000 and more than 1997 in recent years. So I assume that it is on 400 vehicles in random by category and by vehicle model (otherwise it's really not worth it).

In addition ABE (A Bonne Entendeur - TSR) who postponed the tests on the basis of the TCS-ADAC data, are serious people, and they work for decades ...

These stats are therefore sources secure...

But knowing human nature ... We weight, we weight friends and do not believe everything we are told as raw truths ...

Do not forget either that we are the weak link ... In the maintenance and upkeep of vehicles we play a key role in respecting the maintenance schedule in accordance with the manufacturer's directives.

Pay attention to your moving tool and above all pay attention to yourself! After early prevention, the motto would be:

Safety First!

Hi Alain!

The tests are not mine, if you want more info you have to contact ADAC or TCS directly, they list the procedures on their websites.

A priori, I read everywhere that the breakdowns concern cases immobilization of the vehicle. So no key loss, nor just questions of gasoline failure or other flat batteries - because if they appear, it is only in cases of voltage drop or premature wear due to design flaws and not because of headlights that would have remained on. I point out in passing that in all statistics, account is taken of the "believers" who tell you what they want to tell you about the causes (I no longer remember the percentage but it is quite low and deducted)
