Consumer Reports finds that EVs face more reliability issues compared to vehicles with internal combustion engines
Consumer Reports has released its annual car reliability survey for 2023, and the results are in. Electric vehicles (EVs) have been found to have significantly more problems compared to vehicles that use internal combustion engines. Plug-in hybrids fare even worse, with a staggering 146 percent more issues. Surprisingly, standard hybrids outperform all other groups, with 26 percent fewer problems than gasoline-powered vehicles. These findings shed light on the growing pains that EV manufacturers are experiencing as they navigate new technology and work to improve reliability.
Challenges for Electric Vehicles
According to Consumer Reports, the biggest issues for EVs are failing electric drive motors, unreliable charging, and trouble with battery packs. The complexity of plug-in hybrids, which use two separate powertrains, also poses challenges for reliability. On the other hand, standard hybrids have seen fewer problems, potentially due to their longer history in the market and the expertise of manufacturers like Toyota, Hyundai, and Kia, known for producing reliable vehicles.
Tesla’s Mixed Results
While EVs as a whole struggled in the reliability survey, Consumer Reports noted that the Tesla Model 3 and Model Y were the most mechanically sound electric vehicles. However, Tesla’s build quality continues to be a concern, with issues such as irregular paint, broken trim, malfunctioning door handles, and faulty trunks affecting the brand’s reliability score.
Factors Impacting Reliability
Consumer Reports emphasizes that mechanical issues carry the most weight in their reliability survey. Major defects that affect a vehicle’s performance or result in significant repair costs are considered more important than minor issues. However, smaller problems can still accumulate and impact a vehicle or brand’s overall score. The survey’s results are based on qualitative data provided by survey respondents, with over 330,000 vehicles evaluated in areas ranging from motor and transmission issues to infotainment glitches and minor defects.
Brand Rankings and Model Disparities
Lexus and Toyota claimed the top spots in the reliability rankings, followed by Mini, Acura, Honda, Subaru, Mazda, Porsche, BMW, and Kia. Brands such as Chrysler, Mercedes-Benz, Rivian, Volkswagen, Jeep, Volvo, GMC, and Lincoln ranked lower in terms of reliability. It’s important to note that the results are based on brand-level scoring and may not reflect the reliability of individual models. Consumer Reports considers data from model years between 2000 and 2023, with overall reliability scores calculated by averaging results from 2021 to 2023.
Powertrain and Body Type Influence
The survey found that powertrain options have a greater impact on reliability than body types. Traditional passenger vehicles, including sedans, hatchbacks, and wagons, demonstrated the highest overall reliability scores. SUVs, crossovers, and minivans followed suit. Surprisingly, pickups ranked last, which can be attributed to truck manufacturers coming from less-reliable brands and the integration of new features. All-electric pickups had the most problems among all vehicle types.
Conclusion:
Consumer Reports’ annual car reliability survey highlights the challenges faced by electric vehicles in terms of reliability. While EVs and plug-in hybrids struggle with issues related to electric drive motors, charging, and battery packs, standard hybrids have proven to be more reliable. The survey also emphasizes the importance of brand reputation and experience in manufacturing reliable vehicles. As the electric vehicle market continues to evolve, it is expected that manufacturers will address these growing pains and improve the reliability of their offerings.
