Example complaints

“When we started the engine, the awning deployed and almost injured one of us. We have already supposedly had this problem repaired due to a recall. Obviously it is still a danger to ourselves and others.”

NHTSA complaint #11598417, filed 2024-07

“This is in regards to cooling fan overheating and causing fire. My closest dealer scheduled me for the recall knowing why I was coming in. When I arrived they told me it was a lengthy repair but confirmed it would be done by the end of day. I changed my plans around this and when end of day came they said the did not have the parts on hand to complete the recall and needed to order them but confirmed the vehicle indeed needed the recall parts. why would they schedule the service, check on the timeline, and then figure out they didn't have the parts? …”

“The Blind Spot Monitor turns itself off spontaneously. Complained to dealer for 18 months but they were unable to replicate. I finally realized I could lock in the fault if the headlights were left ON. Mechanic was able to determine the vehicle thought there was a trailer attached which disconnects the monitor intentionally. Cause could not be determined but a lighting module was replaced as it was their best guess. It has not reoccurred since and may have been resolved but I am reporting this as many owners of '21 Promasters have reported the same issue on a model specific forum.”

NHTSA complaint #11482075, filed 2022-08

“The blind spot detection system randomly turns itself off. The problem is the van is quite large with lots of blind spots, and you think the system is working because you have it turned on and it turns off by itself. Chrystler is not concerned with the problem, nor do they have a fix for it. This a safety concern that needs an immediate fix. The potential for loss of life is extremely high with this defect.”

NHTSA complaint #11464719, filed 2022-05

“The contact owns a 2021 Ram Promaster 3500. The contact stated that the screen display was black and the back-over prevention camera was inoperable. Additionally, the speedometer was blinking and causing a distraction. The radio and hands-free calling were inoperable. The contact received notification of NHTSA Campaign Number: 25V552000 (Structure). The contact called an unknown local dealer and was referred to a Dodge dealer for assistance. The contact called the local dealer and was informed that there was no warranty coverage on the vehicle and the parts were not yet available. …”
