The most common reliability issues with electric vehicles (EVs) include the following:
- Battery Issues: Problems with the EV battery pack are frequently reported. While battery fires are rare and no more common than in conventional cars, when they do occur, lithium-ion battery fires can be difficult to extinguish. Battery reliability remains a concern for some models, sometimes affecting the vehicle’s overall dependability.
- Electrical Systems and In-Car Electronics: EVs often feature advanced electrical accessories and infotainment systems, which can lead to frequent problems. Reports highlight issues with non-motor electrics, satellite navigation, infotainment systems, and 12-volt batteries as common fault areas.
- Charging Components: Some EVs have experienced charging problems, particularly related to the vehicle’s onboard charging system rather than external chargers. This has impacted reliability ratings in certain models.
- Climate Control and Sealing Issues: Faulty seals can allow water ingress, posing risks given the extensive electrical components in EVs. Poor sealing also causes draughts, increased noise, and less comfortable rides.
- Mechanical Components: Although EVs have fewer moving parts than conventional cars, some models have reported issues with brakes, motors, and motor electrics. However, these tend to be less frequent compared to electrical system problems.
- Higher Overall Problem Rate Compared to Gasoline Cars: Consumer surveys show EVs have about 42% more reliability problems than gasoline-only cars on average in recent years, an improvement from previous years but still lagging behind hybrids and conventional vehicles. Plug-in hybrids face even more issues due to their combined electric and combustion engine systems.
- Repair Time and Costs: Repairs related to electrical and battery issues can sometimes be slow, with a significant portion of EVs staying in workshops for several days or longer. Repair costs vary but can be substantial depending on the fault.
In summary, the most common reliability issues with EVs revolve around battery performance, electrical systems and accessories, charging components, and occasional sealing problems. While EV reliability is improving, they still tend to experience more problems than conventional vehicles, primarily due to their complex electrical systems and new technologies deployed in these cars.
