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 was driving down the road and all of a sudden all the lights on the dash lit up and then the vehicle completely shut down, with no power. This happened while I was driving, so thank god it happen late when there was no traffic. I immediately smelled electrical burning and there was absolutely no power to the vehicle. I had to have the vehicle towed to the dealership. The dealership determined that the alternator burned up and damaged the battery. This exact issue is recall t36 but jeep states that that recall does not apply to my vehicle because I have a 220amp alternator. Obviously, if my vehicle experienced the exact same symptom that the t36 recall is for, the 220amp alternator is also affected. The initial repair cost me $1500. A month later I had to have another repair for $3000, due to electrical issues, where the parking assist and blind spot assist modules went out, along with a headlamp motor assembly. It has been 3 months since that repair and now I have more electrical issues. The check engine light has come on again and I get a service 4wd system, the heat is intermittent, and my temp gauge doesn't move. I have been emailing back and forth with jeep customer care but they just keep saying that the t36 alternator issue doesn't apply to my vehicle.

My 2012jeep grand cherokee will stall as I'm coming to a stop. It doesn't alert with any codes when this happens. It is now doing this on a daily basis. The body shop informed me that a part is still not available for this issue. It stalled trining onto a on-ramp, while I was in a roundabout, as I approached a stop sign. It is happening at deceleration. No code is sent any time it stalls. The music is till playing, all lights are still on. I know it has stalled because the power steering is out and engine is off. I put the car in neutral press the break and started button to make it go again. Totally not safe while in a roundabout let alone anytime.

My alternator burnt up and ruined my computer in my jeep as well. I was driving my car and many of the lights on the dash board went out. My power steering also went out. The alternator was so hot, it crumbled and melted the casing. Chrysler will not admit to the alternator being faulty or needing to be replaced in the recall for the vehicle, stating it was not one of the alternators affected.

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.

Engine shuts off while driving, I was getting off the highway slowing down from a high rate of speed and my engine just shut off. I d id not even know the engine was off until I tried to turn and had no power steering or brakes. There was no warning lights no check engine light. All the lights and radio was still on. I had to put my jeep in park then start it again and it started right up. It has happened twice in one week. I am terrified while driving now that it is going to happen again.

Starting issues, starts up and quickly cuts off. All lights and power are on. Plenty of fuel in tank but not overfilled. I think it is the fuel injection area. I worry it will just cut off due to that while driving. This has happened at least 3 times in the past 3 weeks, it is becoming more frequent.

4 times in the last 3 weeks, the last time just today, as I was decelerating and turning right while getting off highways onto exit ramps, the steering wheel felt like it locked - the power steering turned off, as did the power brakes - I had to coast, and the rpms showed 0, although all the lights were still on. I was forced to put the car in park - while still on the exit ramp - turn off the car and turn it on again to get it to drive normally. Which it did, as if nothing had happened. But it's unnerving and certainly unsafe, and a quick search on the internet reveals it seems to happen quite frequently to other jeep grand cherokee 2012 drivers.

While driving home from work during rush hour traffic on the highway, the red battery light came for the first time since I owned the vehicle. Within minutes of the light appearing, the jeep's air conditioning went off, all warning lights appeared on the dashboard and the windshield wipers turned on (without prompting them). All three of these things happened within seconds of each other so I tried to pull over to the side of the highway but the jeep lost all power and stalled in the right lane of the highway. There was absolutely zero power so I was unable to turn my hazard lights on or put the car in neutral to roll to the breakdown lane (see attached picture). I then had to exit the jeep into oncoming rush hour traffic in the left lane and luckily made it safety to the shoulder where I called 911 and triple a for a tow. The jeep was towed to my local mechanic who said the alternator failed and that he had to unplug it from the battery since it was still producing excessive heat hours after it arrived there. I then called the fca customer service and referenced recall t36, since the exact same thing happened as the description provided (although I did not have any recalls on my VIN). They put me in touch with the local jeep dealership to set up an appt so I paid for another tow there. The next day I receive a call from the service dept that my alternator failed, which drained my battery, which broke my module powertrain control computer totaling $2,134 in repairs. They cannot confirm nor deny that my jeep is part of recall t36, but regardless since my VIN does not have any recalls on it, that I have to pay in full and that if down the road there is a recall that I will get reimbursed. I then call the fca customer service back and they check their internal system and confirm that I am not part of recall t36 and there are no outstanding recalls for my jeep.
