In a December 2020 report, Mitchell outlined how electric vehicles have a higher part replacement count (versus repaired) in comparison to their combustion engine counterparts. Fenders, door shells, quarter panels and deck lids all showed lower repair percentages, with only hoods as the known exception. Mitchell attributes the differences to the materials used in order to achieve the lower weight targets to offset the vehicle battery weight.
In addition, Mitchell noted longer repair duration. Seeing average (keys-to-keys) cycle times of 10.7 days for electric vehicles and 9.5 days for ICE cars.
Of note, Mitchell also reported a greater number of DTC fault codes in EVs at time of repair (13.26 vs 8.83).
