2019 Jeep Wrangler: sudden loss of power

Filed Oct 12, 2026 · Brakes, Steering · OH

FCA US sent me a written warranty extension (15 years/150,000 miles) for the instrument panel cluster on my vehicle, covering a blank EVIC display with no digital speedometer, fuel level, temperature, odometer, or PRNDL. My vehicle has this condition intermittently. As I was traveling approximately 55 mph my power steering, antilock brakes, speedometer, fuel gauge, traction control, all-wheel drive, and emergency brake warning lights came on/off. I actually lost power steering and was unable to turn the vehicle off. I reached out to Jeep and advised them of this and that I received the letter for the instrument panel cluster XZ1 and I thought this was related. I read the letter to them word for word, and they had the dealership perform the recall on my clutch. I didn't know until all of the same things happened again and I checked the receipt to confirm the work performed. I reached out to Jeep the same day and that was more than a week ago. I now have a new service transmission light. My vehicle is not safe to drive and they still don't even know why I called. My case number with Jeep is 98166358.

The 48-Volt Lithium-Ion eTorque Hybrid Battery Pack (Mopar Power Pack Unit/PPU) on my 2019 Jeep Wrangler Sahara Unlimited (~55K miles) failed. The failed component may be available on video by the dealership. Check engine light first appeared early XXX. Earliest dealership appointment was late August 2026. At that visit, dealer diagnosed DTCs P0A94 (recurring, including P0A94-03) and U0412, and performed a software update flashing the BPCM (Battery Pack Control Module) firmware from 05057870AN to 05057870AV per a Technical Service Bulletin. This was covered under warranty at no charge; vehicle was returned to me. Days later, the check engine light returned along with a battery warning light and additional indicators, including ABS among others I could not fully identify. The vehicle then lost power and stopped running while in the roadway, disabled in an active lane of travel — a safety hazard to myself and surrounding traffic. Vehicle was towed to the dealership XXX. On this second visit, the dealership attributed the failure to moisture exposure and corrosion at the PPU connector/harness, denied warranty coverage, and charged me $4,561.90. I received the repaired vehicle XXX. I opened a case with Stellantis Customer Care (Case #XXX) with case manager [XXX] to request a technical review of the failure and the warranty denial. [XXX] stated he contacted the dealership five times seeking information or resolution and received no response. He offered rental car reimbursement up to $50/day during the repair. Dealership diagnosed and repaired the vehicle on both occasions. No known inspection by manufacturer, police, or insurance beyond the review requested under Stellantis case #XXX.

I drove over a rough patch/bump in the road. A ton of warning messages and failure lights activated on the dash. In addition to the check engine light, there were warnings for electronic stability protection, sway bar disconnect, ABS failure, power steering failure, shift lever malfunction. In addition to these malfunctions a failures, the windshield wipers turned on un-commanded and the radiator fan went into the highest possible speed, the digital engine temperature gauge failed, and both the digital and analog speedometers failed. This happened on a arterial road, losing power steering and braking at ~30mph unexpectedly was a shock, but manageable. At highway speeds it likely would have led to an accident or collision. Unfortunately, I don't have any documentation of the failure lights and systems failing, but it had happened several times prior to this occurrence, albeit only with dash warning lights, no actual system failures. After the system failures, I stopped driving the vehicle. The problem appears to be somewhat widespread and is caused by a failing CAN-C BUS. A quick google search will reveal NUMEROUS descriptions on the same dangerous issue. This thread seems to clearly expIain the root of the issue with the CAN-C BUS: [XXX] I replaced my old CAN-C BUS (p/n 68321746AA) with a new part and it appears to have resolved the issue. I have saved the old CAN-C BUS for inspection if the federal safety agency is interested. It looks exactly like the failed BUS in the linked reddit thread above.

Driving on interstate 35 south in fifth gear. There was a loud BANG! and then we lost power. Barely made it off a tight overpass and we saw the smoke. The car was quickly on fires we got out as it started to engulf the jeep with flames. It was a total and complete loss - and very dangerous.

So driving about 50-55mph, the dash lights lite up like a christmas tree. Everything from ABS, shifter lock, sway bar, airbags, traction control, aux battery and some other things that i can't remember. Engine lost power, power steering and unable to shift out of park. I took to my local dealer, I didn't buy it from them, and they diagnsoed the issue of a faulty ABS module. This module has been in the stage of "engineering" for over a year. I spent $900 on one ABS module that was available out of 5 in the US from another dealer and to get 20 minutes down the road only to have it happen again. The vehicle was at the dealer for 5 weeks. The new part was to become available on May20th. Two days ago the service manager called to tell me that they pushed the date to Aug 20th. This will be almost 2 years in this process with this part. The manager then proceeded to tell me it will probably be longer as Jeep went to a new vendor and it is redoing the part. I know of hundreds of other owners in the same boat. Jeep star techs say they can't diagnose past this part so I am paying on a big paper weight since November 23. I have started a case with Jeep customer care only for them to say they can't do anything financially or anything other than help expedite the issue. This is a lost cause as it is still being developed 2 years later. My GM of the dealership said he has 4-5 others at his lot in the same boat and a number of other owners with vehicles like myself at the house. I feel the need for someone to put pressure on the vendor to help with getting a recall on this situation.

Loss of power on the highway, check engine light, battery light, PCM light, Service start/stop system light, stalling and shutting off when put into reverse. Code for MGU. It’s an etourqe Jeep Wrangler, no alternator and no aux battery. It’s been at a dealership since March 6th. They’ve replaced the MGU twice, which is a $15,000 part. They’ve replaced belts, belt tensioners, a crank shaft sensor and opened a star case and cannot remedy the issue. It still stalls and dies when put into reverse. Losing power and being unable to accelerate on the highway is exceedingly dangerous. The vehicle stalling and dying in any scenario is exceedingly dangerous. Not only to myself and the people in my vehicle but to others around me. The issue has been reproduced multiple times at the dealership and they cannot correct the problem.

While driving, traction control light came on. Eventually went away after shutting off vehicle, but engine light came on. Things escalated a week later when all warning lights starting coming on while I was driving and I lost power steering. I took to the dealership and they said several wires had rubbed against a condenser. The fixed the wires. Approx. 2 weeks go by with no problems. Then my Jeep was idling in a parking lot and all the lights start coming on and what I assume was the engine fan started running. It sounded like the Jeep was going to blow up the way the fan was running. I shut the Jeep off and when turned back on, the engine light was on and was able to drive it home. Took it to the dealership and as sitting in the parking lot, it again had all the warning lights going off and the fan went crazy again. It has now been at the dealership for two weeks. No answers. I’ve done research on line and there are lots of people experiencing the same problem. Needs a recall! This is absolutely dangerous to be occurring when driving.
