NHTSA Complaint #11583654 — 2017 JEEP GRAND CHEROKEE

Bought my Jeep used in Sept 2023. For the first time hooked it up to my small trailer to pick something up. Pulled around and went to reverse and the rear park assist braking jammed on. At first I wasn't concerned. I knew there was a way to turn them off based on my jeep manual. Unfortunately, the park assist would not turn off. Neither the park assist button on dash nor the settings in the computer screen would turn them off. The light on the dash button would turn on for 2 seconds but then turn right back off. In the computer settings , I would click the rear park assist to uncheck it. It would uncheck for a few seconds then check mark would come right back again. I tried to turn off the front park assist in the computer just to see what would happen. I can't turn those off either. This is extremely dangerous. I was very lucky I discovered this before I left my property. What if I was in a busy place, road, parking lot, etc. So I do have an appt with my dealer tomorrow, who claims to have never heard of this issue before. . But after doing simple google searches on the internet, I found numerous instances of many Mopar vehicles, like my Jeep GC, Dodge Durango, Chrysler Pacifica, etc. who have had the same exact issue when they try to tow something and cannot turn off the Park Assist feature to back up with a trailer attached. I also called the FCA US Customer Service line to tell them about this and they said they had never heard of this problem. Yet in the many forums I found where people have posted about this issue, they have had to get software update done on the Park assist module to fix this issue. So it is known, but FCA is not admitting to it being an issue. This should be a recall, or if nothing else, considered a necessary upgrade. Also found you have a report in your system already on this issue and I found a Jeep service bulletin related to this issue as well. I will see what the dealer says tomorrow.
