BMW i4, MINI Electric Top J.D. Power EV Experience Study

Public charging remains the least satisfying aspect of owning a battery-electric vehicle according to the new J.D. Power 2024 U.S. Electric Vehicle Experience (EVX) Ownership Study. It measures how satisfied battery-electric vehicle owners are with their ownership experience. While researchers cite quality and cost of ownership as the top factors influencing satisfaction, it says public charging issues continue to frustrate owners.  

The new J.D. Power study ranks the BMW i4 highest overall and among premium BEVs, while the MINI Cooper Electric takes honors as the highest-ranking mass market BEV for a second year in a row.  Both models rank highest in their respective segment on the strength of their performance in the vehicle quality and reliability factor. Each model scores more than 60 points (on a 1,000-point scale) higher than their respective nearest segment competitor for that factor.

“The increase in the EV share of the new-vehicle market, reflected by seven new rank-eligible models this year, is a notable step in the transition toward vehicle electrification,” said Brent Gruber, executive director of the EV practice at J.D. Power. "Many products are hitting the mark and resonating with shoppers but, at the same time, the decline in satisfaction with public charging availability should serve as a warning because concern about access to public charging is a key reason many buyers currently reject BEVs. For EVs to reach their full potential, this issue needs to be resolved."

Following are key findings of the 2024 study outlined in the J.D. Power release:

• Public charging isn’t just bad—it’s getting worse: The J.D. Power study finds that the public charging experience continues to be a major source of EV owner frustration. Further, researchers say non-Tesla owners indicate that the situation is deteriorating. Among mass market BEV owners, satisfaction with public charger availability is 32 points lower than a year ago. “The industry should view this lack of improvement as a critical issue that requires decisive action,” Gruber said.
• Mass market BEVs deliver higher quality than premium BEVs: According to the study, owners of mass market brand BEVs experience fewer problems with their vehicle than do owners of premium BEVs. Eleven of the 14 ranked mass market models outperform the premium brand market average in total problems. “Quality and reliability are the most important drivers of a positive EV ownership experience,” Gruber said. “As EVs extend to the broader market, minimizing problems will be key to meeting consumer expectations.”
• First-time BEV owners are less satisfied than BEV veterans:  J.D. Power also says buyers new to BEV ownership are less satisfied than those who have previously owned a BEV. This year, the satisfaction gap between the two groups is 28 points, whereas a year ago, the gap was 14 points. Overall satisfaction among first-time BEV owners has declined 16 points from 2023. Battery range and public charging availability are the two factors in which the gap between previous BEV owners and new owners is greatest.
• Most BEV owners say they’ll consider a BEV again, but first-time BEV owners may be more fickle: First-time BEV owners say they are open to considering non-BEVs in the future. However, almost half (48%) say they will consider a plug-in hybrid vehicle (PHEV) and 39% say they are willing to consider hybrid or internal combustion engine (ICE) vehicles. Meanwhile, 38% of previous BEV owners say they are willing to consider a PHEV and only 19% would consider a hybrid or ICE vehicle for their next purchase.
• PHEVs might not present a good alternative to BEVs:   J.D. Power says recent news reports have suggested that plug-in hybrid vehicles could solve many of the issues plaguing BEVs, such as range limitations and lack of public charging availability. However, it says this year’s study finds that PHEV owners are, on the whole, much less satisfied with their vehicle than are owners of BEVs. Overall satisfaction with PHEVs is 629, while mass market BEVs (718) and premium BEVs (750) score much higher. “Plug-in hybrids may not be the simple solution to solving early issues with full battery electric vehicles,” Gruber said. “Expected lower running costs is a top purchase reason for EVs but satisfaction with the cost of ownership is much lower for plug-in hybrids. Plug-in hybrids retain the costs of maintaining a traditional powertrain yet without the benefit of the extended electric driving range found in full battery electric vehicles.”

Study Rankings

BMW i4 ranks highest overall and highest in the premium BEV segment with a score of 800. Rivian R1T (789) ranks second and Rivian R1S (778) ranks third.

MINI Cooper Electric ranks highest in the mass market BEV segment for a second consecutive year, with a score of 770. Ford Mustang Mach-E (764) ranks second and Hyundai IONIQ 6 (759) ranks third.

J.D. Power says the number of award-eligible models in the premium segment has grown from five to eight year over year. Award-eligible mass market models have increased from 10 to 14. Satisfaction among owners of premium EVs averages 750, while satisfaction among mass market EV owners averages 718.

About the Study

J.D. power says its annual EVX study, now in its fourth year, focuses on the crucial first year of ownership. The overall EVX ownership index score measures electric vehicle owner satisfaction in both premium and mass market segments. The 2024 study includes 10 factors (in alphabetical order): accuracy of stated battery range; availability of public charging stations; battery range; cost of ownership; driving enjoyment; ease of charging at home; interior and exterior styling; safety and technology features; service experience; and vehicle quality and reliability.

The study is conducted in collaboration with PlugShare, the leading EV driver app maker and research firm. This study sets the standard for benchmarking satisfaction with the critical attributes that affect the total or overall EV ownership experience for both BEV and PHEV vehicles. Survey respondents for the 2024 study include 4,650 owners of 2023 and 2024 model-year BEVs and PHEVs. The study was fielded from August through December 2023.
