I am writing to formally lodge a complaint regarding the ongoing issue with the ABS control module in my vehicle. For the past two years, this component has been faulty, leaving me without ABS functionality, traction control, and proper braking performance. As a result, I have experienced several dangerous situations in which my vehicle was nearly involved in accidents due to these safety deficiencies. Despite my efforts to resolve the matter, I have been unable to obtain the replacement part. I have contacted multiple dealerships, suppliers, and even Mopar directly, yet I have been given no estimated timeframe for delivery. I currently have the part on order, fully paid for, and after two years there is still no indication of when or if it will become available. This situation has created serious safety concerns for both myself and other motorists. …
I had repairs done to my Jeep in April 2024. At that time, I was made aware that my ABS control module was faulty and no longer functioning. I have been periodically checking with my mechanic and online to check the status of this part, only to find that it has been an ongoing issue with some models having this part unavailable since 2019. At the end of October 2025, I began having a major safety issue in which my Jeep's engine will shut off without warning and the only reason I will be aware is because the wheel will no longer turn easily (trying to turn without power steering). In addition, there will at times be a fluctuation of power either having a an extreme spike or drop in RPMs causing the Jeep to lurch while driving. The cruise control cannot be used with this issue, and I have also experienced malfunctions in the traction control (i.e. …

My ABS module failed, which is a very well know issue with the 2014 to 2018 models. When the ABS module failed I was driving the vehicle and it went into fail safe mode while I was on the freeway service road. The speedometer stopped working and the vehicle would not go over about 20 mph. The vehicle was fine one minute and then I had no control of how fast I was going. I was with traffic that was going 60 mph and it could have been extremely dangerous for me or other drivers. The vehicle has been at the dealership since October 3rd, 2025 and has not been drivable due to this issue. It has not been inspected by anyone other than the dealership. There were warning lights but I was told that it was fine to drive until the part was available. It is currently on a national backorder for the last 18+ months without an estimated arrival date. …
I was driving the vehicle at 30 miles per hour and the engine accelerated to 60 miles per hour on it's own. before I could get it to stop. This occurred on 4 different occasions of the vehicle accelerating on it's own. The vehicle was only able to get under control by stepping on the brake hard placed the vehicle in neutral and shut off the Key. Some one could of been killed. No Dick Chrysler dodge stated they would have to drive it to see if there was an issue and charge an outrageous amount of money to determine if there was an issue. I know there is an issue. No one has inspected it as there was no accident There were no warning signs that came on. The first occurrence of the issue was on 8-
Driving sometimes with cruise on and sometimes not or going up a slight inclined the car will lose RPM goes down and then back up. I Was merging on to a highway went to give it gas and RPM goes down and I had 2 semis coming up on me so had to pull over to shoulder. It is very unsafe because you just dont know when it is going to do it. Have had it in to dealership computer and no code. But very very frustrating. They have put computer on and drove around and of course it wouldnt do it. We are at our end of the rope we don't know what to do. Service dept just said if it doesn't throw a code cant do anything. I guess when we get hit they wiil do something.
The ABS light on my instrument panel has been going off for Since April 2025. I have attempted to order a replacement ABS Control Module, but Stallantis keeps canceling the order with no reason provided. This appears to be a long ongoing problem, and others have reported waiting years for a replacement. I have also heard reports that Stallantis is no longer making the part. I understand that NHTSA has forced a recall on other Jeep/Ram ABS Control Modules, so I'm not sure why one has not been placed on the Jeep JK series.
