Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“The EGR cooler recall has affected my truck and there is not a fix for the recall that was issued in october 2019. I am experienced a reduction in fuel economy by about 20% since the check engine light has come on. The check engine light has also caused other features of my vehicle to longer become operable (remote started will not work with check engine light).”
NHTSA complaint #11300685, filed 2020-01, 130,000 miles“There is a considerable difference in throttle response currently upon initially starting vehicle. It makes it quite difficult for the truck to accelerate as intended shortly after starting. There have been several incidents already in which I have had to stomp on the accelerator to avoid a collision as I was not expecting the truck to crawl along versus it's standard acceleration.”
NHTSA complaint #11300023, filed 2020-01, 75,000 miles“The vehicle was moving down the road as I'm driving the truck just looses all power cuts off and I have to jerk it to side of the road to be towed to dealership. It's the tone wheel for crankshaft and crank shaft position sensor. And when taken to dealership they have no parts to fix my trucks and I was given a case worker with FCA or dodge and they can't get the parts it's been 3 months.”
NHTSA complaint #11378512, filed 2020-12, 89,000 miles“Driving on I -29 and we smelled comething like antifreeze then smoke. Truck lost power then got it back and was going to try to make it to an exit but pulled over when smoke coming from under the hood. Opened the hood and saw fire! Called 911 and fire dept came but in a matter on minutes the truck burned up completely.”
NHTSA complaint #11279319, filed 2019-11, 80,000 miles“After completing the approved emissions modification, per the FCA-epa lawsuit settlement, I've noticed substantial turbo lag and shifting issues (holding gear too long). This is particularly dangerous when pulling out onto streets or expressways where I need to accelerate up to speed quickly. There is a 3-5 second lag before the turbo begins spooling and my truck begins accelerating.”
