The 8 least reliable cars according to ADAC in 2022

The German ADAC automobile association Reliability Index for 2022 evaluates 132 models of 22 makes between three and ten years old, of which at least 10,000 were registered in Germany in some period between 2012 and 2019. The ADAC Reliability Index is calculated from the number of Yellow Angel roadside assistances per 1,000 registered vehicles.

According to ADAC statistics, the Yellow Angels had to provide roadside assistance approximately 3.49 million times in 2021. This is 3.1% more calls than in 2020. The most common reason for car assistance is still a problem with the starter battery, which accounts for 46% of all breakdowns. The second most common reason is the engine’s fault and electronics issues (15.5%). Problems with the bodywork, steering or suspension come in third (14.8%), followed by faults with the generator, starter and wiring (10.3%). The ADAC reliability index does not take into account problems that the driver usually causes himself (e.g. empty tank or tire defects).

For all cars, you will also find links to their recalls. You can also search for recalls by Make and Model on our special page.

The least reliable cars according to ADAC index

Among the vehicle models most prone to breakdowns in the 2022 ADAC breakdown statistics are the Smart Forfour, which is now no longer in production, and the Hyundai i20, which is only more reliable since the 2016 model year. According to ADAC, you also have to be careful with the Renault Clio of the 2014 and 2015 model years. The Toyota C-HR is also experiencing more frequent failures, while the new Toyota Corolla is having battery problems. The Ford S-Max has already ranked poorly in the past, as has the Volkswagen Sharan. The ADAC also recorded a high number of breakdowns with the Opel Insignia.

The Toyota Aygo, Audi A1, Mini and Renault Captur, on the other hand, are good choices in terms of reliability, according to the ADAC analysis. On-road faults also rarely affect the Suzuki Vitara from the 2016 model year onwards, the Audi Q3 and the BMW 1 Series.

What the owner should do?

If you read about a recall that you think may affect your car, you should make immediate contact with a dealer or workshop that’s been officially authorised to perform repairs on behalf of the manufacturer and ask for the details.

If you wish to know more about eventual problems of a specific car (e.g. real mileage, potential traffic accidents damages, odometer rollback, repairs, etc.), then we suggest going to HPI-Check.
