One third of car failures are due to wear

Survey reveals the top 10 car parts most likely to fail due to wear and tear.

Insurer Warranty Direct states that, according to a recent survey, 34.4% of all failures for cars between three and seven years old were due to wear and tear, with suspension arms responsible for 5.86% of repairs.

Ball joint repairs were the second most frequent wear and tear failure according to the data, with steering racks, turbo issues and water pumps making up the top five most common faults.

The results of the survey show a mixture of component part and minor part failures in the top 10. The lowest average repair cost for the most common fault was £150, and the most costly repair averaged £1,378.65 for gearbox failure. 

Managing Director of Warranty Direct, Duncan McClure Fisher, said: “The statistics highlight the importance of checking the small print on longer term new car warranties and after-market policies. 

"It’s not reasonable to expect manufacturer warranties to cover parts that wear out but, on the flip side, motorists are not necessarily aware that, as their car gets older and wear-related failures become more frequent, they won’t necessarily be covered.”

Road Safety Week

Ensuring your car is in good working order is especially important at this time of year when driving conditions are worsening. This and other aspects of car ownership will be highlighted during Road Safety Week, which takes place between 22 and 28 November.

Which Car? is taking an active role in Road Safety Week, hosting a Live Q&A session on Tuesday 23 November to answer your questions about child car seats.
