EVs benefit from simpler constructions, lacking traditional engine components and motor oil, which reduces the potential for breakdowns compared to ICE vehicles.

The ADAC explains that the complexity of internal combustion engines, which consist of hundreds of parts, increases the likelihood of failure.

Improvements in technology, including better software and battery systems, have contributed to the overall decline in breakdowns for electric vehicles.

Battery issues are the most common cause of breakdowns for both EVs and ICE vehicles, accounting for 50% of EV breakdowns and 45% of ICE breakdowns.

A recent study by the German Automobile Club (ADAC) reveals that electric vehicles (EVs) are significantly more reliable than internal combustion engine (ICE) cars, averaging just 4.2 breakdowns per 1,000 vehicles compared to 10.4 for ICE cars.

However, after a weak showing in 2024, E-Vehicle sales surged in March 2025, with around 42,500 new registrations, marking a 35.5% increase compared to the previous year.

This finding reaffirms previous ADAC analyses, now supported by a larger dataset that reflects the increasing number of electric vehicles on the road.

In contrast, certain Toyota models, such as the C-HR and Yaris, have been noted for high breakdown rates primarily due to starter battery issues, prompting the company to enhance battery performance.

While EV reliability is improving, the long-term perspective on older EVs remains uncertain, although current models show significant advantages.

Despite improvements in reliability, electric car sales in Germany are currently stagnating due to a lack of buyer incentives and persistent range anxiety.

In 2024, the ADAC recorded over 3.6 million breakdown service deployments, with EV breakdowns increasing by 46% due to a rise in the number of EVs on the road.

Notably, the Hyundai Ioniq 5 had the highest breakdown rate among EVs at 22.4 per 1,000 vehicles, largely due to issues with its integrated charging control unit.
