Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“Truck died in traffic. Lost all power steering, brakes, etc. Almost caused a multiple vehicle accident, and left me stranded in the middle of traffic until I could get assistance to move. There was no warning or notice before the truck just quit working. A warning light came on after the truck died and stated exhaust system failure. See dealer immediately .”
NHTSA complaint #11399710, filed 2021-03, 6,972 miles“Have a squeak that started about 200 miles ago, (have 4900 mile on truck). Did some research and many other people have this problem with the 2019-2020 cummins 6.7 motor. It seems to be some sort of pulley or the belt. The truck is brand new with only 4900 miles and should not have any squeak coming from the belts or pulley. People are having to replace pulleys and belts 7 plus times and still the problem hasn't been fixed. Dealer I took my truck to couldn't fix the issue. Fca needs to address this.”
NHTSA complaint #11372512, filed 2020-11, 4,500 miles“This is the worst truck I've ever purchased, a simple fix needed to the pulley tensioner and the clutch fan is needed..been to dealer twice going a 3rd time . The fuel pump cp4 is a danger to drivers and pedestrians as these trucks are meant for pulling heavy loads and mostly on interstates which makes it a danger. The cp3 is needed back in the trucks as there is a horrible fuel pump chatter at this point and an iminant failure is coming soon. Also the truck rolls in park like 5 feet for no reason while off in park”
NHTSA complaint #11384318, filed 2020-12, 6,500 miles“On september 19, 2020, purchased a vehicle and traded in a 2013 chev. On 09/27 we were driving home engine light comes on, the vehicle has less than 900 miles.. On 09/28 vehicle taken to the nearest dealership( not purchased from) in which no one would pay to have towed. It took a week to be told a new transmission was needed. Was given a run around on the timeframe for repair. Chrysler and dealership decided to have the vehicle towed to the dealership where the truck was purchased. Promised to have a transmission on 10/14. …”
NHTSA complaint #11375110, filed 2020-11, 700 miles“I have a check engine light that came on. I took it to the dealer and they said it is a P0542 code for heating element relay. There is a technical service bulletin out for this known issue. I still have power train warranty left on my truck but they’re claiming it isn’t covered. I went as far as to add a bank ram air intake for over $1000 to help eliminate a complete engine failure. Any help would be appreciated”
