Car house owners are experiencing decrease ranges of auto dependability after three years of possession, in accordance with the J.D. Energy 2024 U.S. Car Dependability StudySM (VDS), launched right now.

“Traditionally, VDS mannequin outcomes mirror the outcomes of the respective mannequin yr within the J.D. Energy Preliminary High quality Research, so a deterioration of auto dependability is uncommon,” mentioned Frank Hanley, senior director of auto benchmarking at J.D. Energy. “This could probably be attributed to the tumultuous time throughout which these autos had been constructed, and house owners are retaining their autos for for much longer. Actually, the common age of autos on American roads right now is roughly 12 years, which underscores the significance of constructing a automobile designed to face the take a look at of time.

BEVs are most troublesome (256 PP100), adopted by PHEVs (216 PP100). Hybrids (191 PP100) and gasoline autos (187 PP100) fare considerably higher. At three years of possession, tires are a sore spot for BEVs, with 39% of homeowners saying they changed tires previously 12 months—19 share factors greater than house owners of gas-powered autos.

Highest-Ranked Manufacturers
Lexus ranks highest general in automobile dependability for a second consecutive yr, with a rating of 135 PP100. Amongst premium manufacturers, Porsche (175 PP100) ranks second and BMW (190 PP100) ranks third.

Toyota ranks highest within the mass market phase, with a rating of 147 PP100. Buick (149 PP100) ranks second, whereas Chevrolet (174 PP100) and MINI (174 PP100) every rank third in a tie.
