2012 Jeep Grand Cherokee: ABS light or ABS activating

Filed Sep 25, 2026 · Electrical · NY

The alternator failed. It was the Safety Recall P60 (the federal safety agency 14V‑634) remedy alternator, installed by an authorized FCA dealer when the recall was completed on 08/30/2021, as FCA confirmed in writing. On 09/24/2026, at 41,275 miles, the vehicle had no electrical power and would not start. An independent New York State registered repair facility diagnosed the failure as "no power," "not starting," and "bad alternator (burning)," and replaced the alternator assembly the same day. The remedy alternator failed about 5 years after installation. The vehicle averages under 3,000 miles per year. The mileage at installation is in FCA's records and is UNKNOWN to me. Safety risk: the P60 recall states that these alternator diodes can fail rapidly with no output or a short to ground, which can disable ABS, electronic stability control, and the engine and body controllers, and can cause vehicle shutdown while driving and an underhood electrical fire, with limited or no warning to the driver. This failure is consistent with that description: total loss of power and a burning alternator. Had it failed while driving, the vehicle could have shut down in traffic. Warning lamps or symptoms before the failure: UNKNOWN. Availability of the removed alternator for inspection: UNKNOWN. FCA has not inspected the vehicle or the component. It declined to cover the repair, first stating that the recall was completed and no recall is open, then stating that completed recall repairs are covered for only 24 months. It made no finding that this failure differs from the recall condition. In its 14V‑634 report, FCA stated that the remedy alternators used the same diodes as its 180 amp alternator, which it said did not exhibit the condition. In 2017, FCA recalled 180 amp alternators (the federal safety agency 17V‑435) for diode thermal fatigue. I ask the federal safety agency to evaluate whether P60 remedy alternators are failing in service and whether the P60 remedy was adequate.

We were about an hour away from home (in the mountains) and our Jeep had been running fine. We had stopped for a while and when we got back to our Jeep and started it, just about every warning light on the dash board came on and wouldn’t go off (the brake light, check engine, airbag, ABS, etc.) The middle of the dash was also flashing different messages…”service park assist and service power steering”. We started to drive and the car was jerking really hard while it was shifting gears. We think it was getting stuck in a high gear because it would hardly drive after we stopped at a stoplights. We turned our hazards on and just tried to make it to an auto parts shop. Our windshield wipers were automatically coming on and the speedometer and RPM needle were both going up and down really quickly. We spent just shy of two long months without our Jeep while it was in the shop. The mechanic ultimately replaced the clock spring and the TPIM. Meanwhile, I joined a Jeep Grand Cherokee Facebook group and it seems like this is a pretty common issue in Jeep Grand Cherokees. It was a costly repair and was very difficult for us to go without our second car for two months. I really feel like this issue needs to be addressed by Jeep.

I have had multiple lights pop up on my dash, usually after it rains, but once for no reason. I will be driving anywhere from 20-65mph and the lights will just pop up. (ABS, brake, and traction control lights) once I turn my jeep off and back on, it disappears. But when the lights are shown, my jeep drives a little differently.

I bought a 2012 grand cherokee used three weeks ago to the day when while driving the kids to the library saturday, suddenly all the warning lights (check engine, ABS, traction control, brake, service power steering system etc.) buzzers, speedometer and transmission position started acting erratically. I pulled over and turned the car off. After a few minutes I restarted it and made it to my driveway when it did it again. I got it into my garage, disconnected the battery cable and let it sit until this morning. When I re-connected the cable and started the car only the check engine light came on. So the wife followed me to the dealer where we dropped it off. Luckily it made the 8 mile trip without any other issues. Then a few hours later the service dept. Called me to say it was the tipm, appx. $950.00, not under warranty, and about 3 to 5 days to fix.

Battery light came on after approximately 5 miles of driving after starting the car, on 10/5/14. This pattern continued for two days, and on the morning of 10/8/14 the car stopped running completely while I was pulling into the parking lot of the auto shop to have it looked at. While driving, I lost power steering and ABS before the car stalled completely a few moments later. I had to have the alternator replaced with only 50,000 miles on the vehicle. Several days later I learned of a new recall on chrysler vehicles due to alternator problems, and today I learned my vehicle was not a part of this recall because I have a 180 amp alternator, and those recalled were 160 amp. I am choosing to report this incident because I believe the failure of my alternator could have caused serious injury to myself or other drivers if I had been traveling at high speed when the battery died, and I believe the 180 amp alternators should be investigated for a possible recall.

We've had odd pedal firmness issues, then received a jeep recall, brought it in and they confirmed (after a horrible customer service experience) that our car has the flawed part, and then gave it back and said they can't do the recall now and will let us know? After contacting customer chat and the call center of jeep na we have discovered there is another recall for the ABS that is likely causing the issue. Our local dealership didn't mention this recall at all and had no problem sending us back on the road with a vehicle with brake defects. I tried addressing it at the local and manufacturer level and they won't even address my safety concerns. They just apologize I am dissatisfied.

I currently lease a 2012 jeep grand cherokee laredo and the other day my wife and son were driving the car and the brakes completely failed. They would not depress even at 5-10 MPH and if completely slammed to the floor the ABS would pump bake fighting the brake pressure. They went through a red right and luckily were not hurt. Later the brakes begin working and we dropped it off at the service center. Once there they test drove it and almost crashed as the brakes would not work. They said it needs a new brake booster, but the part is on back order and there are actually 3 other cars at that service station which needs the same part. I have read a couple posts on various websites with people having the same issue. I was wondering if others have experienced the same issue? (on another note no one has been able to help us with either a loaner car or paying for a rental as the car has 38k miles so technically out of warranty..so that's been fun). Thanks.
