The specific tech issues exacerbating in EVs include false rear-seat warnings, inaccurate and annoying alerts from advanced driver-assist systems (such as rear cross-traffic warnings and reverse automatic emergency braking), and problems with infotainment touchscreens. Additionally, customers experience difficulties connecting their smartphones to their vehicles or losing connection. These issues contribute to a higher rate of problems per 100 vehicles for EVs compared to internal combustion engine vehicles.
Electric vehicles have lower maintenance requirements due to fewer moving parts, simplified mechanical structure, and the absence of combustion engines. This results in reduced need for oil changes, transmission service, and cooling system flushing. Additionally, EVs use regenerative braking, which reduces brake wear and maintenance.
The JD Power survey noted major design changes in Teslas, such as the removal of traditional feature controls like turn signal and wiper stalks, as contributing to the electric automaker's poor rating. These changes may have led to increased problems and dissatisfaction among Tesla owners.
