Tesla's EV quality advantage diminishes due to ongoing repair issues.

• J.D. Power's annual study shows that Tesla is no longer leading legacy automakers in the quality of its new all-electric vehicles.
• Tesla's growing issues are linked to customer dissatisfaction following the removal of traditional controls, such as turn signals and wiper stalks, according to a study.
• Electric vehicles are more prone to issues than traditional gas and diesel vehicles with internal combustion engines, according to a study.

J.D. Power's annual study shows that the quality of new all-electric vehicles from legacy automakers is surpassing that of the company currently losing its lead in this category.

According to the 2024 U.S. Initial Quality Study, the quality of Tesla's battery-electric vehicles and those of traditional carmakers was the same, with 266 problems reported per 100 newly sold or leased vehicles.

In the annual survey of quality, Tesla models outperformed electric vehicles from legacy automakers.

Tesla's growing issues are linked to customer dissatisfaction following the removal of traditional controls, such as turn signals and wiper stalks, according to a study.

Since 2022, Tesla has consistently ranked below average in initial quality across the broader industry, not just BEVs, according to J.D. Power.

The research, which incorporated repair visits data from franchised dealers for the first time, revealed that electric vehicles, including BEVs and PHEVs, experience more issues than traditional vehicles with internal combustion engines.

According to Frank Hanley, Senior Director of Auto Benchmarking at J.D. Power, owners of cutting edge, tech-filled BEVs and PHEVs are experiencing problems at a severity level high enough to take their new vehicle into the dealership three times more often than gas-powered vehicle owners.

Across all repair categories, gas-powered vehicles need fewer repairs than plug-in vehicles, according to a study.

According to a study, electric vehicles (BEVs) had an average of 266 problems per 100 vehicles, which is 86 points higher than the average for gas- and diesel-powered vehicles, which had 180 problems per 100 vehicles. This suggests that BEVs are of higher quality than their counterparts.

Customers frequently encountered challenges with CarPlay and Android Auto, which were their top concerns regarding features, controls, displays, and wireless smartphone integration.

The research found that rear seat reminders cause 1.7 problems per 100 vehicles, as drivers complain about receiving signals even when no one is in the back seat.

Hanley stated that the introduction of new technology has posed a challenge for manufacturers to maintain vehicle quality.
