Electrified vehicles more problematic than others: Owners of battery electric vehicles (BEVs) and plug-in hybrid electric vehicles (PHEVs) experience more problems than owners of gas-powered and hybrid vehicles. BEVs are most troublesome (256 PP100), followed by PHEVs (216 PP100). Hybrids (191 PP100) and gasoline vehicles (187 PP100) fare significantly better. At three years of ownership, tires are a sore spot for BEVs, with 39% of owners saying they replaced tires in the past 12 months—19 percentage points higher than owners of gas-powered vehicles.
Toyota Motor Corporation wins most segment awards: Toyota Motor Corporation’s nine segment awards is the most received by any automaker since 2017 when the Japanese automaker received 10 awards.
The most improved brands: The top three brands showing the greatest improvement in the number of problems are Porsche (33 PP100 improvement); Mercedes-Benz (22 PP100 improvement); and Toyota (21 PP100 improvement).

Highest-Ranked Brands

Lexus ranks highest overall in vehicle dependability for a second consecutive year, with a score of 135 PP100. Among premium brands, Porsche (175 PP100) ranks second and BMW (190 PP100) ranks third.

Toyota ranks highest in the mass market segment, with a score of 147 PP100. Buick (149 PP100) ranks second, while Chevrolet (174 PP100) and MINI (174 PP100) each rank third in a tie.

The parent corporation receiving the most model-level awards is Toyota Motor Corporation with nine: Lexus ES, Lexus IS, Lexus NX, Lexus RX, Toyota 4Runner, Toyota Camry, Toyota Corolla, Toyota Tacoma and Toyota Tundra. General Motors Company receives four segment awards for Buick Encore, Chevrolet Equinox, Chevrolet Traverse and Chevrolet Tahoe. BMW AG receives two segment awards for BMW X1 and BMW X6.

The 2024 U.S. Vehicle Dependability Study is based on responses from 30,595 original owners of 2021 model-year vehicles after three years of ownership. The study was fielded from August through November 2023.

We focus too much on the failures vs how they actually quantify considering production and acceptable failure rates.

Honda is the shocker. I expected Honda close to top.

According to all the YouTube "experts," every single Toyota / Lexus manufactured in the last two years has self destructed with a fiery end within 3 mos. or 3,000 miles of ownership, whichever comes first. And Toyota / Lexus will be bankrupt and closed completely down by the end of the business day.....

So, based on this, I presume Lexus / Toyota taking the No. 1 & No. 2 spots are clearly in error.....

Those reports are before the engine fiasco.

Honda was closer at one time. The fact that they and Nissan are looking at a partnership doesn't surprise me.

What metrics are included in this analysis? Most of these rankings are useless because it measures all complaints with out a severity filter or ranking. Like a total engine failure and rock chipping windshield are considered to be equivalently serious complaints.

I suspect this list is similar to this since top complaint is about tires not lasting long enough, which is not a vehicle dependability but a driver behavior thing.

I’m highly dubious of these rankings.

More anti-ev propaganda!

Or needing new tires. A heavy vehicle with lots of torque (like a BEV) is going to need new tires pretty often.

Consumer Reports’ reliability ratings are also not perfect, but they tend to be much closer to reality than J.D.Power.

And Consumer Reports’ third most reliable vehicle is a PHEV…
