2014 Jeep Wrangler acceleration problems

Filed Jun 4, 2026 · Acceleration, Brakes · FL

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. This appears to be a widespread issue affecting Jeep Wrangler JK vehicles, with many owners reportedly unable to obtain replacement safety-critical ABS modules through Mopar or dealership networks. Because the ABS and traction/stability systems are malfunctioning, the vehicle cannot pass inspection and is unsafe for my family of four, especially during rain or emergency braking situations. This issue affects federally mandated vehicle safety systems, including anti-lock braking and electronic stability control. Owners should not be left without access to replacement parts for critical safety equipment for extended periods of time.

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. The failure first appeared in June of 2024 and the part has been on backorder since then.

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. Furthermore, I am unable to trade in or properly service my vehicle due to this unresolved issue. I find this unacceptable and believe it demonstrates a significant failure in both product support and customer service. I respectfully request immediate action to resolve this matter, whether through expedited access to the replacement part, an alternative solution, or other appropriate corrective measures. My priority is ensuring my vehicle is safe to operate, and I urge you to address this situation without further delay.

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. The cost if I want to have this repaired is $1,200 plus labor.

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.

Gas pedal got stuck full throttle, I was pulling out into traffic and had to accelerate so I pushed the pedal down and when I let off I still was accelerating and just ahead was stop traffic made a hard right into a parking lot and through the shifter into neutral. All the time my foot was heavy on the brake jet still launching forward ... What a hair raising experience and the worst thing my wife thought I was doing that on purpose:)*dt

Hi I was driving the vehicle and the accelerated got stuck while driving for a few seconds . I applied the break but accelerated kept on giving the engine gas when I release the break the car would accelerate forward and finally after about 10seconds the vehicle accelerated went back to normal . There was a lighting volt that came on on the dashboard as a issue and the light disappeared when the acceleration petal came back up .
