What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
The contact stated that while the accelerator was depressed, the vehicle hesitated, jerked, and failed to accelerate as intended. The failure occurred while driving from a stop and while driving at various speeds, causing the vehicle to decelerate during the failure.
Car jerked hard as if I hit something. Very rough. Made a scrubbing sound. Does the same when pressing the parking button. It perks and makes the scrubbing sound. Just purchased Vehicle 2weeks ago. No inspection on it yet.
The vehicle is stalling in the acceleration process. I can feel and hear the stall by the air conditioner going out or fading out when it happens while driving. Pressing the gas and it barely moves at times. Makes a noise now while running. Unknown to whether it's electrical or engine or transmission.

In addition, the contact stated that on multiple occasions while turning into a parking lot, the vehicle's collision avoidance system would engage while in the vicinity of another…
Since early in my ownership, I have experienced a persistent and recurring squealing noise that occurs specifically when releasing the brake pedal after a short stop, and when transitioning from braking to acceleration. This is not an intermittent or weather/humidity-related issue.
My engine light come on. Air flow notification come on. I had a brake cleaner notification come on.
the gas tank is loose upon pumping gas it was found loose today the red mccombs dealership is the only service company who has performed service on vehicle
Upon topping up gas to full or anytime fueling after there is a heavy scent of gas inside the cabin lingering
