About a month after purchasing my used Jeep, I was coming to a stop on a city street and my Jeep powered off completely. After taking the Jeep in to the dealership they fixed the fuel pump relay, which was recalled, and sent me on my way. Since then my Jeep has powered off 5 times (once while entering the highway, twice while exiting the highway, once while making a U-turn under the highway and once on a city street) each time while braking. I've had no power brakes or steering each time.

I experienced a loss of brakes on my Grand Cherokee. I pushed the pedal to the floor and could hear air escaping, but I had very little brake. I had to push exceedingly hard to stop the vehicle. Fortunately, I was not driving in heavy traffic and could get to my local garage. At the garage I was told the booster needed replaced as it had failed.since we had the safety recall done in December 2014 it seemed strange that the brake booster failed. After reading other complaints, it appears that Jeep is aware of the issue and that the recall did not solve the problem. Fortunately, I was not in a serious accident....updated 02/22/17

I had my Jeep in some time ago for the brake booster recall but over the last few months, I have begun to notice a sound of air when I am pressing the brake pedal. Some information that I have found seems to denote this as an issue with the brake booster failing. I need to know if this means that this was not fixed when I took it in for the recall repair as this seems to be getting worse as time goes by. The date below is an estimate based on when this started but it is not a direct day of occurrence. This has been happening for several months now.

My brakes stopped working while stopped at a stop light. The brake pedal kicked back and forced my foot upwards. I was at that point no longer able to depress the brake pedal. I started crawling forward and when the light turned green slowly accelerated to a parking lot. I had to press on the brakes as hard as I was able and slowly came to a stop. There was extreme resistance to depressing the pedal and a grinding/hissing noise coming from engine compartment. It also sounded like the brakes were grinding at the wheels. I was lucky to be at a stop light and not traveling at high speed with my children. The vehicle was towed to dealership and they are diagnosing.

While operating the vehicle on the highway during rush hour (slow traffic) we lost all braking power from the vehicle. Thankfully, we were able to get out of the situation without any harm, however at higher speeds we would have gone into a terrible accident. The vehicle was part of a recall for the brake booster in 2014, and was checked by a Jeep dealer at the time. When we lost braking, the brake pedal became extremely hard, and we weren't able to loose speed at all.

My brake booster replacement for a recent recall had failed, and I was unable to stop getting off an exit on a major highway. I had to coast through a school zone and pull in to a local parking lot, having my car stop as I ran in to a snow bank. I had to have my car towed to a local car shop to assess the situation, then fight with Chrysler to have them tow my car to the original dealer who sold me the car. I have always had my oil changed, tires purchased and all recalls on my car fixed at the original dealer, with whom I had purchased the car from in 2012.

Vehicle engine shut off during right turn in busy intersection without any warnings. Unable to turn or control vehicle. Also the brake on lights come on in the consul during normal operation. Based on other Jeep model recalls, I believe the problem may be related to the tipm-7 module. The vehicle is a Grand Cherokee overlander 4WD. Vehicle was able to be restarted and has not had another failure, however, this is an unsafe driving situation when the vehicle's engine dies while in motion in any road condition. Maybe related to recalls P54.
