Research from Warranty Solutions Group (WSG) shows that repairing electric vehicles is significantly more expensive than fixing internal combustion engine (ICE) cars. WSG’s 2023-2024 EV warranty claims analysis reveals that EV repair costs are 30-50% higher on average.
Common issues with EVs include failures in battery charge control modules, power distribution boxes, warning lights, and shock absorbers. For example, the average cost to repair a battery charge control module is £1,311.12, while fixing a power distribution box runs about £747.65. Warning light repairs average £875.00, and shock absorbers come in around £588.86.
WSG points out that battery replacements alone can range from £8,000 to £12,000 for standard models.
John Colinswood, CEO of WSG, explained: “There is much industry discussion about the cost of EV repairs compared to internal combustion engine vehicles. Many studies show that electric vehicles have lower servicing and maintenance costs than petrol and diesel cars because they have fewer moving parts that can fail.
"However, not all repair shops are equipped to handle EVs, and specialised knowledge is needed to safely work on high-voltage electrical systems. This drives up labour costs, as repairs often require trained professionals, sometimes through the manufacturer or specialised dealers."
The study also cited research from Cap HPI, comparing service, maintenance, and repair (SMR) costs of EVs and ICE vehicles over three years. For example, maintaining a Volkswagen ID.3 costs £1,050 over that period, while a diesel Golf only costs £615, due in part to the more expensive tyres needed for the heavier EV batteries.
According to Gartner Research, next-gen EVs are expected to be cheaper to produce than ICE models by 2027. However, it’s estimated that body and battery repair costs after serious accidents could rise by 30%.
Colinswood also pointed out that braking components on EVs last longer due to regenerative braking, which helps recharge the battery. Despite higher repair costs, he remains optimistic about the future of EVs. He advises dealers to be transparent about potential repair expenses and to highlight the value of extended warranties designed specifically for EVs to protect buyers from unexpected costs.
"Dealers can build trust by discussing repair costs openly and emphasising the benefits of EV ownership and extended warranties," Colinswood said.
