Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“After having to have my engine replaced due to my crank shaft getting clogged with metal pieces on the highway and destroying the engine. I've been having issues with the replacement engine feeling like it's stalling out or losing throttle either during a turn or shortly after. It's never popped and error code and only happens now and then.”
NHTSA complaint #11324543, filed 2020-05, 126,000 miles“While driving at any speed with the gas pedal depressed, the car will suddenly slow down when I hit a pothole or bump in the road. It does the same thing when using cruise control. For example, I'll be driving 50mph and I'll hit a bump in the road and my RPM and speed will drop. If I take my foot off of the gas then re press it, it re engages and accelerates again.”
NHTSA complaint #11207664, filed 2019-05, 116,000 miles“Sometimes when I press the gas, the car will basically take an extra second to speed up, and probably 70% of the times that I press the brakes to slow down or come to a stop, itll (also) take an extra second and itll stall/jerk 1 time, then finish slowing down or stopping....its gradually been getting worse as time passes...the engine needs some work definitely! (I'll feel much more safe after this engine recall is fixed!)”
NHTSA complaint #11386346, filed 2021-01, 150,000 miles“My car's check engine light came on and I took it to the shop for diagnosing. The code p1326 came up and nobody can figure out the problem. My car doesn't accelerate properly and take a minute to shift gears and drive properly. There has been open communication on the issue by other people.”
NHTSA complaint #11228909, filed 2019-07, 110,000 miles“While driving and pressing the accelerator it acts as if its not getting any gas, so when I remove my foot and repress it, it moves right along. It has happened 2 times in the last 24 hours. Now, I exited the car and went into the house and the brake lights are still on.”
