Repair costs rise to over €760 – electrical systems continue to grow in importance

Electrical system most frequently faulty
Familiar patterns also emerge when it comes to the frequency of faults. The electrical system remains the most frequently affected component in both new and used cars. For used cars, this figure has risen from 21.5% to 23.2%, whilst for new cars, at 28.8%, it is significantly higher than the previous year’s figure of 26.1%. The increasing vulnerability of electrical systems thus confirms the trend already predicted in previous years: as complexity grows, both the frequency of repairs and the likelihood of faults increase. For used cars, the fuel system, including the turbocharger, comes in second place at 17.6% (previous year: 18.2%), whilst for new cars, comfort electronics comes in second at 15.2% (previous year: 14.9%). Third place for used cars is taken by the engine at 12.4% (previous year: 13.5%), whilst for new cars it is the fuel system at 10.8% (previous year: 12.9%).

Timing of damage occurrence remains stable
The timing of when damage occurs remains largely stable. For used cars, 27.5% of cases in 2025 saw damage occur within the first 5,000 kilometres (previous year: 27.1%), whilst 20.0% of cases were only recorded after more than 25,000 kilometres (previous year: 21.0%). 26.7% of claims for used cars occur only after more than 360 days (previous year: 25.8%).
