The most common cause for electric car breakdown call-outs is a flat tyre, and electric cars are less likely to suffer a flat battery than petrol or diesel cars, according to data from breakdown provider Start Rescue.

“Our data shows 29% of electric car call-outs are due to a flat tyre” says Lee Puffett, Managing Director of Start Rescue. “This is similar to petrol and diesel cars as many new cars no longer have a spare wheel fitted in order save weight and emissions, and larger puncture holes cannot always be repaired with foam sealant.”

Start Rescue’s data shows that EV battery range is not an issue for electric car drivers. However, they still need to look after the 12-volt battery that powers the same functions as petrol and diesel cars, such as the dashboard and computers which enable the vehicle to start, as well as lights and wipers.

However, Start Rescue’s data shows that EVs are less likely to suffer from a flat battery call-out than petrol or diesel cars. For electric cars it accounts for 23.7% of call-outs compared to 29.7% for petrol and diesel. 

Lee Puffett adds: “Like any car, EVs need to be driven to avoid the 12-volt battery going flat over time. But EVs can be more complex to repair– our data shows a petrol or diesel car is twice as likely to be fixed at the roadside.”
