2014 Jeep Grand Cherokee: brake failure

Filed Apr 18, 2026 · Electrical, Transmission · WI

While driving home from work on March 13, 2026, the alternator in my 2014 Jeep Grand Cherokee (3.0L EcoDiesel) failed, resulting in a progressive loss of electrical power. As battery voltage dropped, the vehicle entered “limp mode.” When I was aproximatly 1 mile from my home when I was forced to stop at a railroad crossing while a freight train was passing. At that time, due to low voltage, the electronic shifter and ignition system became completely unresponsive. I was unable to shift the vehicle into Park or Neutral and was also unable to shut off the engine. The vehicle remained in Drive, requiring constant brake pressure to prevent forward movement. This created an immediate and dangerous situation, as I was stopped very close to a moving train with no functional means of securing or disabling the vehicle. Any loss of braking force or control could have caused the vehicle to enter the path of the train, creating a high likelihood of serious injury or death. After reaching my residence, the condition persisted. I remained unable to shift or shut down the vehicle and was forced to manually disconnect the negative battery cable, which is located under the passenger seat, in order to stop the engine. I am very lucky that I had a small metric socket set in the vehice, that I am somewhat mechanically enclined, and that I have long arms & legs, as this process was extremely difficult. I had to disconect te battery cable while maintaining my foot on the brake to avoid crashing into my garage. The vehicle appears to be designed such that engine shutdown is not permitted unless the vehicle is in Park, while the electronic shifter becomes inoperative during low-voltage conditions. This combination creates a hazardous failure mode in which the driver cannot place the vehicle in Park or turn off the engine during an electrical failure. This incident appears consistent with hazards identified in the federal safety agency Campaign Number 16V240000 (Recall S27). Despite records indicating that rec

While on highway, wipers, lights and horn began on their own. Then car shifted to neutral and brakes failed. I was going 70 miles per hour. I was able to get off the highway and have the car inspected by a licensed mechanic. It is the electrical computer or TIPM. The car is unable to start. This issue is a very dangerous safety issue.

My 2014 jeep grand cherokee ,shut down while I was driving in the issaquah fall city road . Steering wheels locked and brakes failed and everything shut down. I barely made it to the walgreens parking lot where the vehicle completely died to the point where even the keys wouldn't work . I barely made it alive . I am glad I didn't crash into anyone . I had to tow the vehicle later in the day to the dealership . They asked me to drop it off at their garage . Today they got back to me saying , there was an open recall on the vehicle and that caused the alternator to fail and shut down everything . They said because it's an open recall they would fix it themselves as it's covered under some warranty . But they also told me that there is an issue with some oil pressure sensor and the awd system is stuck in awd and they will have to fix it and have me a parts and labor charge of 2000 usd which I have to bear . Is this normal practice . I don't know how the awd system suddenly got into this state . If it's a result of the alternator issue caused by the open recall , wouldn't they manufacturer/dealer have to bear it . . Thanks !!

1 week after the dealership added the water shield to the brakes as required by the recall the brakes stopped working the first time you used them after starting the vehicle. We took it back and we're told it had nothing to do with the recall and the ebt pump needed replacing for $750. We took it to a different mechanic and found that the brake boosters were corroded and the ebt pump was fine. Corroded brake boosters is exactly what the recall was intended to prevent and we should not have had to pay for the work. *tt

On august 4, 2017 after starting my jeep and driving away from parking space I had no brakes at all when trying to stop - fortunately I wasn't going more than 25 MPH when I noticed the problem - I was able to coast into a curb and stop. There was no prior warning and no warning lights and the brakes seemed ok the night before when I parked the car. I had to have the car towed to a dealer where they charged me $718.54 to install a new power brake booster which they said was no longer under warranty. The jeep had 42834 miles at the time. If this had happened on I-25 which is where I was heading I would not have been able to stop at all.
