AA and Autotrader data challenges EV reliability fears as breakdown rates beat petrol and diesel

Concerns about electric vehicle reliability remain widespread, but new AA data suggests those worries are largely misplaced, particularly for fleets weighing up electrification.

An Autotrader/AA survey of more than 2,000 drivers found 44% remain concerned about breakdowns or roadside repairs when considering an EV. Anxiety was highest among drivers aged 75 and over (56%), with women also more likely to express concern than men.

However, evidence shared through The Facts initiative paints a different picture. AA breakdown data shows EVs are actually more likely to be fixed at the roadside than petrol or diesel cars, with an 89% repair success rate compared with 87.5% for internal combustion vehicles. Despite common fears around high-voltage batteries, the AA reports that 12-volt battery failures are a more frequent cause of call-outs in ICE vehicles than EV battery issues.

Fleet confidence is already ahead of the public curve, with multiple industry surveys showing more than 60% of fleets believe EVs are more reliable than conventional vehicles. Repair readiness is also improving, with 81.2% of UK workshops now equipped to work on EVs.

AA president Edmund King said EVs running out of charge represent only a “tiny proportion” of breakdowns and continue to decline. Government ministers added that reliability data is key to building confidence as EV uptake accelerates.
