Selected complaints filed with NHTSA by 2014 Jeep Wrangler owners, lightly cleaned up (personal details are redacted by NHTSA).
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 own a 2014 Jeep Wrangler Sahara JKU with approximately 67,000 miles. The vehicle has experienced a failure involving the ABS control module and related braking/stability systems. Current symptoms include: * ABS warning light illuminated * Brake warning light illuminated * Traction control warning light illuminated * Intermittent speedometer malfunction * Brake pedal occasionally vibrates and becomes soft during operation * Vehicle hesitates for several seconds when accelerating from a stopped position while dashboard warning lights flash The vehicle has been diagnosed by two separate Jeep repair facilities as having a failed ABS control module. I have been informed that replacement ABS modules for this vehicle have been unavailable for approximately nine months and remain unavailable as of today. …
Our ABS Control module has failed. p/n 68145835AE. It's available at any time to inspect. The ABS system does not function. In a rain or snow situation this could cause severe harm to us and others on the road. Our local service center that works on a wide array of Jeep Wrangler products says they have other customers with the same problem on this specific model. It is also reported substantially on online Jeep enthusiast forums. The unit in our Jeep has been looked at by our service center. There are warning lights on the dash indicating the ABS is non-functional. This failed in May 2024. The ABS module also controls speed control and that also is no longer working. It has been this way for over a year. Other Jeep owners with this similar issue have reported the same issue. This appears to be a systemic issue that Jeep is very aware of but has taken no action to correct. …
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. …
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.

Incident: while stopping in traffic with the foot firmly on the brake my Jeep had an unintended acceleration causing a rear in crash. This unintended acceleration happen before on a trip to tennessee in June but was thought to be the floor mat which now is known not to be the case. ( both were witnessed by the passenger) these incidents and complaint were given to Chrysler regarding the experience with the vehicle accelerating and surging. However, Chrysler denied any responsibility regarding the malfunction which resulted in the accident. Because I realized the Jeep was unsafe to drive. I had it towed to the local Chrysler Jeep dealer. Due to safety concerns and to protect life and property. I refuse to drive the vehicle again and bought another car. The dealership where I purchased my new vehicle was told not to sell it until the timp is replaced in the Jeep. …
