When you buy a car with a trusted badge—Ford, Jeep, Subaru, or even Tesla—you expect it to hold up. That’s the whole point of brand loyalty. But the latest reliability data from J.D. Power’s 2025 Vehicle Dependability Study and Consumer Reports’ annual auto survey reveals a frustrating paradox: several models from these “bulletproof” brands are actually among the least reliable vehicles on the road today. Here are five cars that should have been dependable but simply aren’t.
The Ford F-150 is America’s best-selling pickup, and the PowerBoost hybrid variant promised the best of both worlds: truck capability and fuel savings. But real-world ownership tells a different story. The hybrid system is plagued by software glitches that cause sudden power loss, unresponsive infotainment, and false check-engine lights. According to Consumer Reports’ 2025 owner surveys, the F-150 Hybrid has a predicted reliability score of just 2 out of 5, with powertrain and electrical issues topping buyer complaints. One Michigan owner reported being stranded twice due to a faulty transmission control module that Ford hasn’t fully addressed.
Jeep’s flagship SUV carries a heritage of rugged off-road capability and a premium interior. However, the current generation has become a headache for many owners. The air suspension system, standard on many trims, fails prematurely, leaving the vehicle sagging on one side or refusing to adjust ride height. Additionally, the 3.6L V6 engine has been linked to oil consumption issues that lead to costly repairs. J.D. Power ranks the 2024 Grand Cherokee below average in dependability, with 42% of owners reporting at least one major problem within the first year of ownership—far worse than the segment average.
General Motors’ full-size pickup rivals the F-150 in sales, but its reliability numbers are slipping. The 10-speed automatic transmission—shared across many GM trucks—has been a persistent trouble spot, with owners reporting harsh shifting, hesitation, and in some cases, total transmission failure before 20,000 miles. Consumer Reports also notes that the Silverado’s advanced safety systems (Super Cruise, lane keep assist) suffer from calibration issues, creating false alerts. Despite a comfortable ride and strong hauling capability, the Silverado 1500 scores below average in predicted reliability for the second year in a row.
Tesla’s flagship sedan once set the benchmark for electric performance, and many buyers still believe it’s the ultimate EV. But behind the sleek screen and Ludicrous mode lies a growing list of reliability concerns. The notorious falcon-wing doors on the earlier Model X were swapped for conventional ones, but the Model S now deals with persistent touchscreen failures, battery cooling system leaks, and door handle malfunctions. A 2025 investigation by the National Highway Traffic Safety Administration (NHTSA) flagged
