When starting from a stop or rolling slowly under 15 mph, pressing the accelerator pedal — even flooring it — produces no engine or motor response for 1–3 seconds. The vehicle then suddenly accelerates. This occurs intermittently on both electric and gas power. Safety concern because it delays merging or pulling out into traffic.

What owners say
Right turn from stop then try to cleated there is no response from the pedal Will lunge forward and engage throttle if I’m lucky
Unintended acceleration event. Initial condition: Cruise control off. Steering wheel turned 270 degrees ccw, turning left, at a complete stop, released brake, rolling forward at less than 5mph in a confined parking garage. Continuing to turn wheel to left, my right palm accidently engaged the cruise control button on the steering wheel. Cruise control automatically set to 15mph and began to accelerate. I was able to engage the brake again in enough time to deactivate cruise control. This is not the first such incident I've had where the cruise control is accidentally engaged and begins accelerating the vehicle to 15mph. Anecdotally, they have all occurred during left turns. Seeing how it engaged today, I can now understand why I couldn't figure out why it was happening previously. Due to accessibility issues, I typically turn with a single hand while allowing my other to remain capable of grabbing to maintain control. How easily my palm brushed the cruise control unintentionally was shocking.
At a stop, in electric mode, truck will lunge forward as if you were rear ended. Most of the time, transmission failure will occur after some time due to this lunging forward, and it has happened to many truck owners. Electric auxiliary transmission pump tends to be the cause .
(June 14, 2023) While traveling at 55mph the vehicle suddenly accelerated for about 2-3 seconds and several dashboard lights turned on and flashed not available. (ABS, Traction control, Blinds Spot, pre-collision) I safely pulled over turned the truck off, waited a few seconds. Turned the truck back on, and ABS light was solid on the dashboard. I drove another 15 miles stopped again, and when I restarted the check engine light remained solid. After inspecting the truck, I found gear oil leaking from the right rear tire. I removed the plastic hub cap and discovered sheared off axle bolt. Truck was delivered to dealer for repair.
