Example complaints

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

“My truck, with the aisin transmission and single rear wheel, has a horrible throttle delay. Pulling out into an intersection or in front of oncoming traffic is terrifying, because if the delay kicks in, I can put the pedal down and the truck will literally not react for 3-5 seconds. This is also true when trying to accelerate to pass on the highway, avoid another vehicle, etc. It's like the throttle pedal doesn't know you're pushing it for quite a few seconds, and then and only then it will react. …”

“Nhtsa recall number: 17v-562. The description provided in the notice reads: a water pump failure resulting in an engine compartment fire can cause the vehicle to crash without prior warning increasing the risk of injury to motor vehicle occupants or persons outside the vehicle. I contacted the dealer where I purchased the vehicle, tate branch dodge in carlsbad, nm on 11/21/2017. They stated that nothing can be done, even after I asked if I just have to hope that the vehicle doesn't catch on fire, to which they said, yes . …”

NHTSA complaint #11047784, filed 2017-11, 13,000 miles

“Daily occurrence. While dead stopped at light or idling along after lifting foot off of brake pedal, then slowly depressing accelerator pedal, there is a 2-4 second delay before truck starts to accelerate. Feels like a dead pedal. This has become worse as the truck accrues miles. When needing to accelerate quickly, the pedal response is slow to respond and has caused many anxious moments with vehicles bearing down on my rear end. I press the pedal and wait for engine to respond. The truck is a diesel and it does not feel like turbo lag. I had a 2007 diesel and this was not a problem at all. …”

“From day 1 the truck has had very poor throttle response. The big problem is on take off. The truck has a dead pedal with a delay of 3 to 5 seconds before the truck will accelerate. This can make for some dangerous situations. In looking for a solution to this problem I have found there is a huge number of owners complaining of the same thing. It seems chryslers response has been to ignore the complaints and not look into a solution”
