What owners say about the electrical system
Verbatim from NHTSA complaints, newest first
“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”
“My complaint is that I was sold a dangerously defective vehicle with a known, unrepaired “stop driving” airbag safety recall, was not warned about the deadly risk, and am now being told to move and tow the car in direct contradiction to official safety instructions. ### Factual background - The vehicle I purchased has a Takata‑type airbag safety recall that carries a formal “do not drive” or “stop driving” warning because the airbag can explode and kill or severely injure occupants, even in a minor crash.[1][2][3][4] - Federal safety authorities have confirmed that at least 28–29 people in the United States have been killed and more than 400 injured by exploding Takata airbag inflators.[3][4][5][1] - I received the recall notice about two months ago, but I was told the repair parts were back‑ordered, which delayed fixing the deadly defect through no fault of my own.[1][3] - During this delay, the vehicle’s battery became completely dead, and I am now being told by the recall and towing company that I must make sure the car is taken out of the garage, which would require entering and moving a vehicle I have been legally and explicitly told not to drive. ###…”
“The dash displayed multiple warning ICONS and I carried the Jeep to a mechanic. They discovered that the ABS Module, which is the anti braking system, had a fault error and needed to be replaced. After multiple attempts have found out that this particular ABS Module, OEM Part number (68145835AE) is no longer available by Jeep Chrysler and has not been available for the past few years. This means the Jeep is not safe to drive if the roads are wet or icy due to the possibility of loosing the brakes from skidding/loss of control of the vehicle.”
“THE 2012 Jeep 4 door Wrangler had the ABS Control Module internal error failure, this makes the car unsafe to drive. The dealer cannot get repair parts, the car is un-repaired since October 2025. Further, they cannot source the chips for the components, the make cannot provide a delivery date.(UNKNOWN when this will be rectified. Other years of this car have been recalled for this issue. This year has not yet. PLEASE Help us !)”
“In 2020 I bought this Jeep, within the first 3 months I had to replace the TIPM, at $950.00, now 5 years later the same problem, the TIPM is having issues again. Causing the engine to overheat. Jeep is telling me this happens, not at $950 every 5 years, I was told there was a recall initially when they were new. There has to be some sort of recourse, you just can’t sell faulty parts and say it just happens! Thank you [XXX] [XXX] [XXX]”
“The 2012 jeep jk wrangler has serious electrical issues. The jeep randomly stalls while driving and sometimes won’t start at all. Right before it stalls, every light on the dashboard flashes and continues to flash until the car dies. Replacing the battery doesn’t fix the issue. Numerous complaints about jeep wranglers TIPM issues have been ignored by authorities. I suppose people will have to die in a crash or spends thousands fixing the TIPM or electrical issues before getting relief.”
