EVs prove to be less reliable than conventional gas cars

Electric vehicles have proved far less reliable, on average, than gasoline-powered cars, trucks and SUVs, according to the latest survey by Consumer Reports, which found that EVs from the 2021 through 2023 model years encountered nearly 80% more problems than did vehicles propelled by internal combustion engines.

Consumer Reports said EV owners most frequently reported troubles with battery and charging systems as well as flaws in how the vehicles’ body panels and interior parts fit together. The magazine and website noted that EV manufacturers are still learning to construct completely new power systems, and it suggested that as they do, the overall reliability of electric vehicles should improve.

“This story is really one of growing pains,” said Jake Fisher, senior director of auto testing at Consumer Reports. “It’s a story of just working out the bugs and the kinks of new technology.”

Still, Consumer Reports noted that lingering concerns about reliability will likely add to the issues that give many buyers pause when considering a switch to the new technology, joining concerns about higher costs, too few charging stations and long charging times.

The growth of electric vehicle sales has slowed sharply since last year. In June 2022, EV sales were growing about 90% year over year. By June of this year the 12-month growth rate had slowed to about 50%, and automakers have become increasingly fearful that the pace will weaken further.

Reflecting that concern, about 3,900 U.S. auto dealers this week signed a letter to President Joe Biden, asking him to rethink what the dealers called unrealistic fuel economy and emissions requirements that could require electric vehicles to reach 67% of total U.S. vehicle sales by 2032.

Consumer enthusiasm for EVs, their letter warned, has stalled.

“They are not selling nearly as fast as they are arriving at our dealerships, even with deep price cuts, manufacturer incentives and generous government incentives,” the letter said.

The Consumer Reports survey also concluded that plug-in hybrids, which can travel on battery power before a gas-electric powertrain kicks in, are more problem-prone than fully electric vehicles. Plug-ins, Fisher pointed out, contain two separate and complex power systems in which glitches can arise. He also noted that brands that over time have proved less reliable, in general, such as Jeep and Volvo, have started mass-producing plug-in hybrids.

But tried-and-true integrated gas-electric hybrid systems are more reliable than gasoline vehicles, largely because they have been in use for about a quarter-century and the bugs have mostly been worked out, Fisher said.

Consumer Reports derived its survey data from subscribers who owned EVs from the 2021 through 2023 model years and compared them with other vehicle types. In calculating a vehicle’s average problem rate, the organization assigned extra weight to serious problems such as battery or engine failures.

EVs from the 2021 and 2022 model years overall had more than twice the problem rates of internal combustion vehicles. The rates were more closely aligned in the 2023 model year: Those EVs had only 21% more problems than gasoline vehicles, Fisher said.

The narrower gap in problems between EVs and combustion vehicles in the 2023 model year, Fisher said, suggested that the reliability of EVs, in general, is improving. Still, he noted, newer vehicles tend to have lower problem rates that rise as they age.
