The 48V eTorque Power Pack Unit (PPU), BPCM, and associated cables failed on my 2019 Jeep Wrangler, causing the vehicle to stall and lose all acceleration while driving on the highway. All components are available for inspection upon request. In June 2025, a non-Jeep service center identified stored diagnostic code P0A9C-00 (48V hybrid battery temperature sensor circuit performance failure) along with multiple low voltage codes in the power steering system. The technician noted the issue needed to be addressed by an authorized Jeep dealer, as there was insufficient information to perform a repair on the 48V hybrid system. In September 2025, while driving on the highway, the engine stalled and the vehicle completely lost acceleration and would not restart. The vehicle required towing to an authorized Jeep dealer. A sudden and unexpected loss of acceleration and engine stall on a highway creates an extreme risk of rear-end collision and potential serious injury or fatality to the driver and other motorists. The problem was confirmed by an authorized FCA/Jeep dealer who found the same diagnostic code P0A9C-00, along with corrosion buildup on the 48V connector pins and BPCM pins. Two separate FCA STAR cases were opened by the dealer. The Power Pack Unit Battery was identified as the failed component. The dealer confirmed that the 48V cables required for repair are currently unavailable through Chrysler under any parts specifier, meaning FCA cannot supply the necessary parts to remedy this known defect. The vehicle has been inspected by an authorized FCA dealer on two separate occasions nine months apart, with the defect remaining unresolved on both visits due to FCA parts unavailability. Warning symptoms including low voltage codes and the P0A9C-00 fault code were first identified in June 2025, approximately three months before the highway stall event, indicating this was a progressive and worsening defect. The issue was first reported in June 2025 and remains unrepair

Shortly after starting the vehicle and entering roadway, the power steering failed and shortly following an error came on regarding the ABS system. I was able to pull the vehicle over safely, restart and the issue seemed resolved in that use. Next day, shortly after starting vehicle, same errors occurred, but self corrected. The day after that, shortly after starting the vehicle, all systems on the front panel cycled through several error codes, when attempting to shut the vehicle off to restart it, the vehicle would not shut off. Using the standard transmission, I was able to create a stall situation, but the vehicle's electrical would not shut off. After removing the key fab, the electrical system kept activating power systems, even turning on the windshield wipers when the control was in the off position. After 20 minutes and several attempts I was finally able to get the system to completely shut off.

My Jeep Wrangler's instrument cluster randomly shut down while driving. This means I couldn't see the electronic speedometer, odometer, or any other information on the dashboard. There weren't any warning lights before it failed. I had the dealer fix it, but Jeep wouldn't cover the entire cost of the repair, even though the dealer confirmed there was no water damage or external cause. It seems like the instrument cluster just malfunctioned and fried. This appears to be a recurring issue with Jeep Wranglers, and it's concerning that Jeep isn't taking responsibility for a problem that could be a safety hazard, especially when using features like adaptive cruise control that relies on the digital screen. Attached is the repair order and invoice detailing the problem. I also have a video of it mid-failure if you need it. This shouldn't happen with a vehicle at 46K miles, major safety concern.

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.

After coming to a complete stop every time, the Auto Start/Stop kicks in and when it is time to accelerate the Jeep stalls, takes itself out of drive, lights start flashing, radio goes off, and windshield wipers start going. After getting through the disorientation of everything happening and cars honking at you or jamming on breaks to not hit you; one will need to re-step on the break, put the vehicle in park, restart the Jeep (if it starts, sometimes it takes 3 times pushing the start button or it may need a jump started. This is such a dangerous situation. I bought the Jeep in Oct of 2019. Had Batteries (both) replaced in Jan 2021. Still under warranty i took back to them this past Saturday, they said the main battery needed a 117 minute charge and the smaller battery was fine. they let it sit for 45 minutes and it started right up for them. The next morning same thing, struggling to turn over. I am again going to take to dealership as much as i do not want to as this is an on going issue not getting resolved.

About 2-2.5 months ago, our 2019 Jeep Wrangler completely stalled out at a stop light. At the time it stalled, the dash started flashing and gave me many warning lights. I was unable to put the transmission in park in order to try to start the vehicle again. After many attempts, I was finally able to place in park and start the vehicle. I then went thru a drive thru and it did the same thing and left me stranded in the drive thru lane without being able to start it for about 10 minutes. The next day, I was on my way to work and while traveling on the highway at 75 miles per hour, the vehicle stalled out, the dash wigged out and I lost all control of the vehicle including steering. The engine revved up to a higher RPM and I was unable to put it in neutral to try to slow it down and control the vehicle to a safe stop on the side of the highway. There were a couple of close calls with other vehicles due to the inability to control the steering or the engine speed. The next day, I took the Jeep to the dealership and when scanned for codes, there was over 150 codes including losing communication with the Body Control Module. Dealership test drove and the tech had the vehicle replicate the issues and leave him stranded 7 times in one day from and back to the shop. At this time, my concern is the safety of my family. For now it appears that the issue has been resolved, but there have been many similar instances reported with the same danger of crashing. Paperwork obtained from my dealership reflects there was a module that was replaced when the vehicle had less than 8,000 miles that was supposed to fix this issue, however it occurred to our jeep that had less than 25,000 miles on it. The paperwork also states "!!Attention!! This vehicle may have had 7 visits, 69 days down and 8 repeat repairs, service personnel should notify dealership service management and engage FCA service and parts resources." Doesn't this fall under the Lemon Law?

The dash glitches and lights up all of the warning lights, speed and fuel goes up and down then the engine idles high despite not shifting/touching anything. Then it it completely locked up and cannot shift out of park. If it sits for a while occasionally it will start and only have check engine light on and allow you to shift to drive however while driving I have had the entire dash light up and speedometer/rpms going up and down causing it to run higher. It has been back to the dealer twice now for same issue that was supposedly fixed. It says service shifter, my abs are not working and electronic stability control needs service amongst other things. It is very scary when this has happened while driving on the highway with my children in the car and the fact I never know if I will be able to make it to or from work/picking up kids or if I will be stuck in drive/have engine shut off while driving. This has happened more than once in my 3 weeks of purchasing this vehicle and I am scared for our safety. I have had the codes read prior to going to the dealership and it says multiple things are malfuntioning

Vehicle only had 21421 miles on it. We were having issues with the Jeep reveling at highest RPM when turned on. This happened a handful of times and then it began to seem like it was not going to stay started and was going to stall. We took it into dealer for oil change and reported the issue said they couldn’t find anything. Issue persisted took it back and they ran diagnostic said they couldn’t find anything. Still had the issue occurring so took it back and they said it needed a new starter so they replaced that. Then issue got worse and was stalling out and shaking. Took it back again and they are now replacing the engine. This was really shocking. This is the 4th Jeep wrangler I’ve owned in my life and so have NEVER had major issues with any of them before only normal wear and tear type repairs and upkeep.
