NHTSA complaint #11309903, filed 2020-02, 1,200 miles“The vehicle hesitates like it doesn’t want to get up to speed, despite pressing the gas pedal to accelerate. The RPM needle bounces. Dealership has not been able to “replicate the hesitation I feel when accelerating.” They originally tried to say I didn’t tell them the problem was happening when it had time to warm up, which is a lie, I have all the scheduling notes made by the employee who set the appointment up. Dealership said it passes diagnostic testing despite my serious concerns as the owner driving it daily. …”
NHTSA complaint #11573056, filed 2024-02“I have had my lane assist come on by its self a few times, which is very dangerous because it seems to take over and will pull on the steering wheel. I’ve also brought my car back to the dealership a handful of times to have it hooked up to a computer and also someone ride with me because the car will either hesitate to accelerate or stutters and doesn’t seem to want to go when I am between 20-30 miles an hour. Other times when I’m at a light or stop sign it hesitates also. I was told there was nothing wrong with it and they reprogrammed to transmission but it didn’t help at all.”
