Electric and hybrid vehicles: specific maintenance

Electric and hybrid vehicles have partly different maintenance needs from conventional cars. Fewer moving parts in the motor, but battery, electronics and braking need particular attention. Here is what changes.

Motor and transmission

An electric motor has little wear (no conventional clutch on many EV models, no timing belt). Services are often less frequent (every 2 years or 20,000 miles depending on manufacturer). Fluids (battery/motor coolant, gearbox oil) must still be checked and replaced as recommended.

Traction battery

The high-voltage battery is warranted for several years (often 8 years or 100,000 miles for minimum capacity). To limit degradation: avoid 100% charges for daily use if the manufacturer recommends it, limit DC fast charging, avoid leaving the battery flat or full in extreme heat or cold. A State of Health (SoH) check may be offered by the dealer.

Braking

Electric and hybrid vehicles use regenerative braking (energy recovery) a lot, so mechanical brakes are used less. Pads can last longer, but rotors can rust if mechanical brakes are rarely used. Occasional "normal" hard braking and brake checks at each service are recommended.

Tires and air conditioning

Tires: electric vehicles are often heavier and have more instant torque; wear can be faster. Air conditioning: it often cools the battery; a healthy system matters. Cabin air filter and A/C recharge as on a conventional car.

Order of magnitude

Scheduled services at the dealer are often cheaper than for a conventional car (fewer parts/fluids), but out-of-warranty repairs (battery, electronics) can be very expensive. My Auto Check-up helps you track maintenance and symptoms for your vehicle.
