Common EV warranty claims revealed, and most don't include the battery

New data from WarrantyWise suggests fleets and used EV buyers may be worrying about the wrong components, with the majority of warranty claims relating to conventional vehicle parts rather than the electric powertrain.

While high-voltage battery repairs remain expensive when they do occur, they are comparatively uncommon. Instead, the most frequent repair requests involve familiar maintenance items and electrical systems.

WarrantyWise's five most common EV warranty claims:

  • Sensors: Average repair cost £810 (highest £3,270)
  • Central locking mechanisms: Average £899 (highest £4,057)
  • On-board charger: Average £2,159 (highest £10,455)
  • Suspension (wishbones): Average £1,230 (highest £4,119)
  • 12V auxiliary battery: Average £533 (highest £986)

Battery repairs average £6,435, but WarrantyWise says they account for relatively few claims compared with everyday components.

The findings reinforce the importance of preventative maintenance and inspection programmes as EV fleets mature. They also highlight the need for fleet managers to look beyond battery health when assessing whole-life running costs, particularly as average EV repair values increased 10.7% between 2024 and 2025 due to rising parts, labour and inflationary pressures.
