Vehicle stalled without warning. No power whatsoever. Illuminated battery light came on. Noticed a burning odor coming from vehicle. Checked engine bay and noticed heavy smoke coming from alternator for a good 10 minutes. Vehicle would not take a jump nor could I put into gear. Battery is completely dead. Pcm also seems to be fried. Will have to be towed to dealership. Called Jeep costumer care and referenced the t36 recall but my VIN does not fall under it even though vehicle fits exact description of recall. Also noticed that many others are have same problem with Jeep and them not expanding the recall to their VIN. How terrible!! this could have easily been a fatal situation. Jeep needs to take some responsibility and action!.
A week ago my battery light came on in my car on my way home. Luckily I was able to get home before it died. We drove my car to an independent mechanic that we always go to get it diagnosed. My mechanic said I made it just in time because when they went to start my vehicle it was completely dead. They diagnosed that I had a bad battery and replaced it. They also identified that the alternator was bad and said there was a recall on it (I never received a recall notice on this part though). My car was towed to a nearby Chrysler dealership and they completed all the open recalls on it, including the alternator belt. Then my car was towed back to my independent mechanic. After my mechanic ran my car for 20 minutes the car shut off and it was found that the powertrain control module shorted. I immediately called Chrysler customer service to report the issue. It has been over a week and I have spoken to 5 different customer service agents. Every single one has told me something different and a different process I have to follow. My car has been towed back to the dealership and just sitting there. It has been over a week since I have had my car. I just heard from a customer service agent today that the car has to be diagnosed by the dealership and they have to declare that the pcm is not working. I have no idea what will happen after that. I am really trying to get them to pay for this and not go through a reimbursement process because I don't have faith I will actually get reimbursed in the end. I am so disgusted with the treatment Chrysler has given me. They obviously are trying everything to get out of paying this. Well they picked the wrong person to mess with, I will not back down.
The contact owns a 2012 Jeep Grand Cherokee. While the vehicle was parked with the air conditioner and radio still operable, the contact exited the vehicle. Upon returning to the vehicle, he noticed that the air conditioner and radio stopped working, but the windshield wiper blades were moving at slow speed. The contact shifted into drive, but the vehicle was moving slowly and the steering wheel seized. The vehicle was stopped, shifted into park, turned off, and failed to restart. The voltage warning indicator illuminated. The vehicle was towed to an independent mechanic where it was diagnosed with a faulty alternator and battery that needed replacement. The parts were replaced, but the mechanic noticed that the computer was damaged and could not be repaired. The vehicle was towed to another independent mechanic who diagnosed that the pcm needed replacement and there was an alternator recall. The vehicle was not repaired. The contact had the vehicle towed to jt Chrysler Dodge ram of lexington (located at 4838 sunset blvd, lexington, SC 29072 (803) 957-2010) for repairs. The manufacturer was notified of the failure and confirmed that the VIN was not included in NHTSA campaign number: 15v674000 (electrical system). The failure mileage was 113,002.
While driving on freeway, battery warning light lit up, followed by (incorrect) error messages on instrument cluster menu that driver seatbelt was unfastened. All electrical equipment in the vehicle ceased operation, including ac and stereo. I pulled off of freeway and opened hood to find the alternator smoking heavily. This was the exact same failure situation described in Chrysler recall p60, but because my alternator was 180amp instead of 160amp, it was not covered by the p60 recall. The alternator had to be replaced. The alternator failure also resulted in a blown-out pcm, which had to be replaced. This is an extremely dangerous failure that could have caused a car fire, or traffic accident. Chrysler recall p60 should include the 180amp alternators, as well, because they have the same fault and safety issues.
180 amp alternator experienced catastrophic failure causing total loss of all power, battery failure, pcm failure and smoking and burning smell from engine compartment. Experienced loud whinning from alternator while driving immediately prior to failure. Ultimate failure occured as car pulled into parking spot. This is the same issue experienced by 160 amp alternator under recall. It is extremely dangerous and Chrysler/Jeep should be required to fix these issues.
