The Most Reliable American Car in 2026? It's the GMC Acadia

The most reliable American car is the GMC Acadia, topping J.D. Power's 2025 study and outperforming rivals in dependability.

Whenever someone asks me what the most reliable American car is, I usually pause. For years, my answer would have been a shrug. Japanese and European brands dominated my mental reliability rankings. But as I look at the data available in 2026, especially J.D. Power's 2025 Vehicle Dependability Study, the answer has become surprisingly clear. It is the GMC Acadia. Yes, the GMC Acadia. 🚗

That might not be the answer you expected. It is not a Corvette, not a Mustang, and not some exotic American halo car. It is a regular upper-midsize crossover that quietly does its job. And according to J.D. Power, it is the most reliable American car you can buy right now. The Acadia won the Upper Midsize SUV category in the 2025 Vehicle Dependability Study, beating the Buick Enclave and the Mazda CX-9. Those are two vehicles that have built solid reliability reputations, so this was not an easy win.

The 2022 GMC Acadia has a J.D. Power Quality & Reliability Rating of 85 out of 100. That may not sound like a perfect score, but it places the Acadia only five points away from the best category in J.D. Power's metrics. RepairPal estimates its average annual repair cost at $734 per year. That is higher than the $573 average for midsize SUVs, but RepairPal still labels it average overall. In other words, the Acadia will not drain my wallet if something goes wrong.

What makes this so interesting to me is that the Acadia is not the only American car that performed well. Several American models won their categories in the same study, and they deserve attention too.

American car	Category win	J.D. Power score	Avg annual repair cost
GMC Acadia	Upper Midsize SUV	85/100 (2022)	$734
Chevrolet Corvette	Premium Sporty Car	93/100 (2022 C8)	$737
Chevrolet Tahoe	Large SUV	83/100 (best years)	$744
Cadillac XT6	Upper Midsize Premium SUV	84/100 (2022 and 2023)	No data yet, likely similar to Acadia

The Chevrolet Corvette won the Premium Sporty Car category by default, since no other model in that class performed above average. Still, the C8-generation Corvette scored a very impressive 93 out of 100 for the 2022 model year. The Chevrolet Tahoe took the Large SUV crown, also by default, with several model years scoring 80 or above. The Cadillac XT6 won the Upper Midsize Premium SUV category, beating the BMW X5 and the Land Rover Range Rover Sport. That is a meaningful win for Cadillac.

But here is the twist: the most reliable car overall in America is not American. It is the Toyota Avalon. I know, I know. The Avalon has been out of production in the United States since 2022, but its reputation keeps it at the top. Many Avalon model years score highly on J.D. Power's Quality & Reliability Rating, and the 2021 model year earned a stellar 92 out of 100. RepairPal estimates its average annual maintenance cost at just $463, which is lower than other full-sized cars. An iSeeCars study also placed the Avalon eighth overall on a list of vehicles most likely to reach over 250,000 miles, and it was the highest-ranked sedan. The top five spots in that study were all Toyota models, with the Toyota Tundra at number one.

So where does that leave American brands? The 2025 J.D. Power study actually gives me some hope. Buick finished second overall among all brands, losing only to Lexus. Cadillac, Chevrolet, and GMC all scored better than the study average of 202 problems per 100 vehicles. That is a strong showing for General Motors. In fact, all four of those brands are GM brands, which is a big deal for the company.

Not every American brand did well, though. Ford, Lincoln, Ram, Chrysler, and Tesla all scored lower than the 202 problems per 100 vehicles average. Lincoln had 221 problems per 100 vehicles, Ram had 242, and Chrysler had 282. Chrysler even did noticeably worse than Alfa Romeo, which had 211 problems per 100 vehicles. That is not the kind of comparison any American brand wants. It tells me that while GM is moving in the right direction, other American automakers still have a long way to go.

GM itself is not without worries. In 2026, the company still faces questions about tariffs that could affect where it builds cars, and the NHTSA has been investigating a large number of GM-built vehicles with the GM V8 engine over engine issues. Those are serious concerns. But the dependability study shows that GM's core brands are building vehicles that hold up better than many people expect.

If I were shopping for a reliable American car in 2026, I would put the GMC Acadia at the top of my list. It is not flashy. It is not the fastest. It is not the most prestigious. But it won its category against tough rivals, it has a solid reliability rating, and its repair costs are manageable. For me, that is exactly what dependable transportation should be. The Acadia may not scream reliability at first glance, but the data says it deserves the crown. 🏆
