2012 Jeep Grand Cherokee transmission problems

Filed Sep 10, 2026 · Electrical, Transmission · AZ

My 2012 Jeep Grand Cherokee suddenly was stalling, and would not re-start, especially when turning the steering. AAA Tech diagnosed as High Diode Ripple Voltage in the Alternator, damaging the Battery. Needed to Replace both Alternator and Battery at a cost of $1068. Car was recalled under T36, and the repair has a repeat failure again. Jeep Declined to repair or re-imburse the repair costs. More importantly its still a major safety issue, and Jeep is failing their legal obligation to provide a permanent fix, not a temporary fix.

Year: 2012 Make/Model: Jeep Grand Cherokee 5.7 L V8, 4WD Mileage: ~140,000 miles Date of Incident: [Insert date] Location: McKinney, Texas (near U.S. 75 exit) Description of the Safety Issue: While driving normally, the Service 4WD System warning illuminated. Seconds later, the lightning-bolt symbol (Electronic Throttle Control) appeared, and the engine stalled abruptly without warning. All power steering and power-brake assist were lost while the transmission was still in Drive. The vehicle rolled backward on a slight grade as if in neutral. Attempts to restart the vehicle failed. Even CarMax technicians, at whose lot the vehicle came to rest, were unable to start it. A strong hot/burning electrical odor was present immediately after shutdown. This indicates a possible overheating or shorting event in the electrical or fuel-relay system (TIPM or throttle-body circuit). Had this failure occurred on U.S. 75 at highway speed (80–85 mph), I would have lost steering assist and braking ability in heavy traffic — a situation that could have led to a severe collision or injury. I respectfully request that the federal safety agency review this case as a potential recurrence or expansion of the existing recall group. The combination of a sudden stall, complete loss of control systems, no-restart condition, and electrical-burn odor constitutes a serious and ongoing safety defect that endangers vehicle occupants and others on the roadway. Supporting Information: – CarMax technicians confirmed the vehicle would not restart. – Recent maintenance included new fuel pump, injectors, hoses, and cooling-system components (~$10 K). – Warning lights: “Service 4WD System” and “Electronic Throttle Control (lightning-bolt)” appeared immediately before stall.

Re: AQ14-003-FCA-Consent-Order-7-24-2015 & 2019 Safety Recall [Manufacturer Recall Number V62 & the federal safety agency Recall Number 19V‑813]. FCA hasn't been in compliance with either of them regarding 'my' vehicle. 2015 Consent Decree implies should have been notifying car owners of any type of recall. 2017 recall was cancelled & 2019 safety recall was issued 4 years after the decree, 1 year after I bought the car, a safety recall was issued. Wasn't notified. 2 years later "I" contacted FCA (now Stellantis) to get my vehicle remedied by repair or replacement. Parts were shipped to a dealership but they used it on one of their customers. I asked for another set of parts. After that, absolutely nothing has happened up to now. Keep in mind FCA had my information (email, phone & address) either from me emailing or speaking with a customer rep. It's been over 3 years since last heard from FCA. On my side I no longer have ability to contact them directly since they became Stellantis. 49 U.S.C. § 30166(f); 49 C.F.R. §§ 573.6(c)(10); 577.5(a), 577.7(c)(1), & 49 U.S.C. § 30165(a)(1); 49 C.F.R. § 578.6(a) the federal safety agency fined FCA/Stellantis > $100 million for 'not' making an effort to send recall notifications of any type of recalls directly to owners of their vehicles within a reasonable amount of time also to remedy the issue. If they don't comply $7,000 per violation & only remedy is replacing the vehicle in question. It's exact issue! Been over 7 years waiting within a reasonable remedy, it never happened. This is a safety issue. I was assured it'd be fixed, never was. I'm putting my life at risk & others driving. Unbelievably the part sent to me the dealership without my consent & knowledge gave it to one of their customers. I called to complain & expected another part to be sent out to another dealership. It never happened. I never spoke to anyone at FCA since then 3 years ago. There doesn't need to be a lengthy investigation. It shows my recall status as open. Proof of noncompliance.

This Jeep has had 2 recalls and repairs related to the fuel pump relay. The first recallrepair did not fix the issue, Jeep then replaced the relay again, which did not fix the issue. Then there was a NEW recall and repair, which also did not fix the issue. The car still has the exact same issues, the car will randomly stall soon after being started. I’m not sure what to do at this point bc I feel unsafe driving this car and it is my only vehicle.

While driving through the intersection after slowing down at light, vehicle completely stalled, turned off in the middle of the intersection and wouldn't start back up. I had to have it towed to dealership. I have had it in dealer prior to this incident for stalling issues just out of nowhere. They simply said they cannot find a cause. This is dangerous to me because vehicles behind me don't know that I am stalled out and almost hit me. Prior to this last time, I have been able to restart vehicle by putting in neutral and getting it to move on it's way, but still scary while vehicles behind me don't know that I was going to stall out. This last incident, I had to be pushed off of the road and then towed to dealer. Hoping they can find the cause and fix.

The transmission shifts strangely, and it seems like it cannot decide which gear it needs to be in for normal operations. It also causes the vehicle to stall while driving. Also, at times it stays in only one gear, and you cannot even shift gears manually. Intermittently, the vehicle starts out in a higher gear, and it doesn’t correct itself, so acceleration is way below what it needs to be. I have been fortunate to avoid a few crashes due to the stalling.
