Example complaints

Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“When accelerating (either from a stop or a rolling stop) and then braking and then accelerating again, the engine will hesitate. Some call this dead pedal but I feel it's dangerous because it leaves vulnerable in traffic to a collision. It's happened to me numerous times and again today. I was at a 4 way stop and proceeded to accelerate when it was my turn, about 1/3 way into the intersection, a vehicle traffic ignored the stop sign and attempted to cross my line of travel. I had to break and then immediately accelerate and the truck hesitated which left me in the intersection. …”

“Dead accelerator pedal. When applying accelerator there is a period of time when nothing happens. This is particularly concerning as it leaves the vehicle occupants and the vehicle essentially dead and in harms way while trying to maneuver in traffic, merging, turning, emergency avoidance, etc.”

NHTSA complaint #10795302, filed 2015-11, 2,000 miles

“The new dodge Ram equipped with cummins diesel experience a dead pedal, or pedal delay when pressing the gas pedal 3/4 to full throttle. This poses a serious risk when needing to get out of the way, or move the vehicle under emergency circumstances. This happens under all conditions: stopped, rolling, under acceleration etc. If you push the pedal too far the truck will not respond to operator commands and will take 1.5-2 seconds to start picking up speed. This is a seriously dangerous situation and someone is going to get killed or seriously injured. …”
