2012 Jeep Grand Cherokee Electrical System Problems

The contact owns a 2012 Jeep Grand Cherokee. The contact stated that while driving approximately 5 MPH, the brake pedal was depressed while slowing down; however, the RPM elevated to 5,500 RPM. The contact stated that excessive force was needed to depress the brake pedal. The vehicle was stopped, turned off, restarted, and operated normally. Additionally, the remote start feature was not operating properly. After remote starting the vehicle, the brake pedal was difficult to depress. The contact also stated that a phone call was ringing through the radio even though the phone was not in use. The contact researched online and believed that the vehicle had been hacked.

The failure mileage was approximately 94,000.

All dashboard lights came on while cherokee shut off on the parkway yet allowing me to steer to the side shoulder. Is this a symptom of total integrated power module TIPM.

I brought my vehicle to the Jeep of concord for a fuel pump relay recall and oil change on 11/12/25. Prior to 11/12 the vehicle did not experience any of the issues described below. On 11/13/25, a dealership representative sent an inspection video stating the vehicle was in immaculate condition following the recall repair. However, within less than 24 hours, the check engine light illuminated, and additional issues began occurring intermittently. After the recall work, the vehicle began experiencing intermittent warning lights, including service four wheel drive, traction control, and check engine. These warnings appear unpredictably and are sometimes accompanied by loss of vehicle functions, creating unsafe driving conditions. The vehicle has also experienced overheating since these issues began. Sometimes turning the vehicle off and then on would temporarily correct the problem if it would recrank. The failures occur intermittently, making them difficult to reproduce or diagnose, and they pose serious safety risks, including the potential for sudden loss of power, steering assistance, or drivability while the vehicle is in motion. On multiple occasions, the issues have left me stranded. I returned the vehicle to the dealership on 1/8/26. On 1/9/26, I received an inspection video from the dealership identifying a transmission issue for the first time. The rep stated they “double-checked” the recall wiring but confirmed that no manufacturer engineer inspected the vehicle, despite my request to escalate this as a STAR case due to safety concerns. The intermittent warning lights, overheating, and transmission concerns remain unresolved and Stellantis refused to escalate the issue. The dealership currently retains possession of my vehicle. I am concerned the recall repair may have been performed wrong or inadequately inspected, resulting in ongoing intermittent safety-related failures affecting multiple vehicle systems. I am requesting that NHTSA investigate & confirm

When driving the vehicle it just stalls. No warning and all power is lost including power steering which makes it VERY dangerous to all occupants of the vehicle and others on the road.

Alternator causing engine stall also electrical issues

My car apparently overheated which made my oil filter melt and explode, popping my oil filter cap off making oil go all over my engine, ground and everywhere else. I was going about 20 mph when I realized my car was feeling weak on power and it was about to overheat. I then started to smell and see smoke. So I stopped my car in the middle of the street immediately, put on my hazard lights, and turned it off instantly. As soon as I got out, oil started to pour out everywhere. I then popped the hood to see a whole lot of smoke going everywhere. I wasn’t sure what happened, I just got the car 3 and half months ago, they said the car was top of the line, why am I having issues like these now? I did get my oil changed from pit stop (superlube) on lake street in Aurora Illinois, 3 days before that happened. I had to manually push my car to chihuahua tires, where they told me it was my starter, so they fixed my starter, and then told me it’s my gasket. Now apparently my head gasket is gone, and it’s going to take thousands of dollars that I don’t have. I’m already paying off the $800 for this starter repair that I didn’t really need :/ and I’m still playing for a car note on a car I’m not even driving! I can’t get to work, I can’t make money, this is depressing! I got this car because they said at Carfect that my jeep was perfect and in great condition. At this point I had over 10+ mechanical issues wrong with it, now this happened and I cant manage this. This is too much money for me. I need help, direction, a new engine, something! I just got this car! I did nothing wrong, I don’t have thousands of dollars to fix this issue! Please help.

The car cuts off in middle of the road n won’t shut on brought a new fuel pump and it’s still shutting off the electric light pops up on dash when cutting the engine on the car gives the cranking engine power sounds but doesn’t cut on mechanic put in new fuel pump and now think it’s a electrical problem the steering is tight backing up and it has steering fluid this has been happening since 3 months ago I wanna say it comes n goes I’ve got it inspected twice and they inquired about the fuel pump which I have gotten fixed and the car still continues to shut off in the middle of traffic which can cause an accident

I have 2 issues with this vehicle issue#1 the tire pressure sensor acts up on the front driver side tire pressure goes down to the low 20s then when driving it goes up to 43 and then back down to the 20s , the other is that I was driving from Pennsylvania to New York and the car stalled in New Jersey with no warning I was at the far left side of the highway and came close to getting rear ended twice real bad (my girlfriend who was and is pregnant) was on the passenger seat was hysterically crying because of how close we came to having an accident that would’ve cost us our lives , the car took 5 minutes to start again and we were escorted to safety by tow company that saw us through the cameras they have on the bridges very thankful to them escorting us cause we surely would have died that night

2012 Jeep Grand Cherokee HEMI. As traveling whether on highway or on streets no matter the speeds the Jeep tends to just stall out out of no where especially when braking and coming to a stop it completely shuts off, no engine, no steering and then must have to engage into park or neutral to push to start up the Jeep again. It is very dangerous and scary any time it happens and even more so when happens on highway. It has been an on going issue since I bought the vehicle in NOV. 2018 but only happens every once in a while and out of the blue when it does. I did reached out several years ago to the manufacturer Mopar Jeep Chrysler but they had no solution for me. I had a case number with them but it was so long ago I cannot remember now. I did have the recall on the fuel pump relay in which I thought that would resolve my issue but unfortunately it did not and I still experience this Jeep stalling out at any point while driving, onto braking, and then to the stop. Any help? Thanks

While driving the road whether highway our town… my vehicle will stall out. I can’t safely pass because my car loses power.. check engine light starts blinking then traction control lights come on and then battery light. I have to turn the car off after turning flashers on put it in park and restart after a few seconds. This vehicle is VERY UNSAFE to DRIVE.

As I was driving my Jeep Grand Cherokee, I was in the process of braking in order to turn, when the power steering stopped working as the engine stalled. I was able to pull over to the side of the road, put it back in Park and was able to restart it like nothing had happened. According to other owners with a similar issue, all the symptoms describe an open Safety Recall for a failing Fuel Pump that may cause the engine to stall. However, when I search the VIN on the NHTSA website, it states that there are no open recalls. The symptoms are identical to what is outlined in the recall. The only warning that came on was "Check the Gas Cap" warning.

So I just bought this car from a dealer about a year now and I was driving down the fwy. Heading to work And suddenly my car turned off and my steering wheel got really hard to make any turns there was no way I could’ve stopped in the middle of the fwy. To stop and start the engine. luckily I was able to pull over and check the car I was full on gas and I looked up common issues that could turn off a running engine checked all fuses didn’t see any problems with it didn’t see any sort of corrosion in the battery cables and their was no check engine on the dash board. Theirs also been times were it randomly takes a long time cranking and won’t start right away so I literally wait for the engine to sit for a while and start the car. My guess it’s the crankshaft position or the fuel pump going out but that’s why I’m here to find out if theirs any recalls related to this issue. I’ve been told their was a recall for a relay issue

My 2012 Jeep Grand Cherokee (Jeep GC) frequently and numerously experiences sudden shutdowns while driving. Consequently, not only do I lose power to various electrical features, but the power steering assist and power brake booster also become inoperative. This issue has been acknowledged by Jeep for other model years, but regrettably, they have failed to accept responsibility for it for the 2012 model, despite its significant impact on safety. Interestingly, there is a known safety recall by the National Highway Traffic Safety Administration (NHTSA) for the 2008 Jeep GC related to a Wireless Ignition Node Module (Safety Recall P57 / NHTSA 14V-567). This raises concerns about potential similarities between the issues experienced in different model years. Numerous individuals have reported similar problems in online forums and posts. In an effort to address the issue, I have reached out to Jeep's customer service and my local dealership. However, both entities seem unwilling to acknowledge the existence of a broader systemic problem, claiming no knowledge of the root cause. It is essential for Jeep to take responsibility and promptly address this serious safety concern in all affected model years, ensuring the safety and peace of mind of their customers.
