2012 Jeep Wrangler acceleration problems

Filed Oct 21, 2026 · Acceleration, Brakes · FL

Warning lights for Traction Control parking Brake and ABS are all on. Diagnosis is a Bad Brake control Modular. Dealer said it is super common and a defective part. They want $3000.00 to fix it but Mopar does not make the part anymore so they cant help me anyway unless I bring them one from a junkyard. Jeep forum says DO NOT Drive the vehicle with a bad Brake controller, and I quote the Mechanic "ABS module failure poses a clear and present danger to drivers, passengers, and others on the road”. so now what do I do? Cant get the part, the Manufacturer does not make the part, and the vehicle is a hazard on the road. Stelantis knows this is an issue for every Jeep Wrangler owner but does nothing to assist. They won't even produce a replacement part. PLEASE force JEEP to do the right thing and fix our ABS modulars

ABS, Traction control and Brake lights came on. Veh has 45000 miles on it. Was advised the ABS module is bad. Part is no where to be found, and no dealer can order it. Basically the vehicle braking system is questionable on the road without ABS or traction.

On my way to work on city street, slight curve in road, it was raining. Cruise control set at 50mph. I heard the chime and glanced at the dashboard. Cruise control light was out, ABS light, anti-skid light and parking brake light were on. Touched the brake slightly and jeep went into a skid. Luckily no one was next to me.

Beginning of feb., lost power on freeway. Went from 65 to 40 MPH and could not accelerate. Engine and traction lights came on. Exited the fwy and drove to dealer where I was turned away due to high volume. Left my jeep at the dealer the following day with this issue and to correct campaign #v51 recall. The engine light wasn't lit anymore and dealer couldn't find anything wrong with it so I picked it up. Couple of weeks later, I failed the smog check I need to register my jeep, and an engine code showed up, p0394. I took it to other places where the same code showed up and was recommended to take it back to the dealer. Going downhill, my father experienced the same while driving my jeep. Beginning of march, omw to the dealer on the fwy, I lost power again and the engine and traction lights came on. I showed the dashboard to the service advisor, explained the continued problem and the code showing up. I left my jeep there for several days because they couldn't reproduce the problem and didn't know what was causing it. The code was cleared when I picked it up. The following day, as I was making a right turn into a parking lot, the engine stalled. I used gravity to partly move back down as there was another car driving into the lot. I put it on "park" and I was able to restart the car. No engine light this time. This morning I lost power driving to the first stop on my street (stop on my side only). I had already entered the t-intersection but could not accelerate to turn left. I put it in "park" then back to "drive" and accelerated normally. There were no cars around because of the corona virus, but I would have been hit on the driver's side if a coming vehicle (who has the right-a-way), decided not to slow down.

Lightning bolt symbol and check engine light come on while driving. Vehicle goes into limp mode and starts running roughly. If turned off and allowed to sit will start up again just fine. Check engine light typically turns off after a couple more trips and runs just fine until it randomly does it again. Has been sometimes minutes, other times weeks between episodes. Have had accelerator position sensor replaced, throttle body replaced, and wiring to throttle replaced. Keeps happening. Has happened when vehicle is parked, sitting at light, normal driving, and while driving at highway speed.
