As part of the study, experts examined 200 models that have stable demand in the used car market. All cars participating in the analysis were between 5 and 10 years old. For each of them, a special "reliability index" was formed, based on information about the frequency of service visits and the amounts spent on car restoration. It turned out that among cars that broke down most often and most seriously, the lion's share falls on the premium segment. The most typical reason for visits to mechanics was electrical failures.
Top 15 cars with the lowest reliability on the secondary market
If you have one of the models from this list in your garage, it is worth immediately taking care of finding spare parts at reasonable prices, for example on Avto.pro. The rating shows for each car the average and maximum restoration costs (in the UK), as well as the typical malfunction that owners face. This data allows you to know in advance what to be prepared for.
- Tesla Model S. On average, repairs cost $1174, in the worst case — $5152. The central locking system most often fails.
- Ford Ranger. Average repair costs — $1458, maximum — $16,378. The exhaust gas recirculation valve turned out to be the most vulnerable element.
- Audi A7. Repairs cost approximately $2845, but can reach $13,135. The main problems are related to injectors.
- Mercedes-Benz S-Class. The average restoration cost is $1666, the highest is $19,050. The most common breakdown is a malfunction of the exhaust system sensor.
- Peugeot RCZ. On average, repairs cost $1217, the upper limit is $7715. The most problematic unit is the turbine.
- BMW M5. Average costs — $2487, maximum — $11,850. Most often, owners encounter suspension breakdowns.
