Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Grand Cherokee

  • 60,000 miles


The contact owns a 2004 Jeep Grand Cherokee. While driving at various speeds, whenever the accelerator pedal was depressed, the vehicle failed to accelerate. While at a stop sign, the contact attempted to accelerate forward, but the vehicle was unable to move. As a result, another vehicle crashed into the driver side of the contact's vehicle. The air bags did not deploy. There were no injuries. A police report was filed. The vehicle was taken to the dealer where it was diagnosed that the front hood, driver's door, the front frame and panel, the fuel injector, and transmission needed to be replaced. The vehicle was repaired; however, the vehicle was inoperable. The manufacturer was made aware of the failure. The VIN was unknown. The failure mileage was approximately 60,000.

Jeep accelerated without stepping on gas. Accelerator cable did not seem to operate smoothly, when applying, felt somewhat "rough/nothy" owner agreed to change as suggested. Cable changed total $477.39 in 5/2010.this time car was towed to Jeep dealer. C. stated Jeep accelerated on its own, towed in. Jan. 13,11 Jeep towed in to Jeep dealer for bucking and accelerating on its own, no issue was found. May 13,11 towed into Jeep dealer, changed several components and $1,074.68, never had a definite answer, and after each incident took its toll on my nerves, scared to death to drive my Jeep, which I purchased to make our family safe. Fast forward, 11/23/2015 this Jeep once again started accelerating and racing in park and with the hand brake up. My Jeep has 64, K and is taken care of, looks great. But, once again I cannot risk putting my family or myself in it to drive. I have found numerous stories like this and some a lot worse. My instincts were to just shut the engine off and I did all4 times over the years. I am now on a fixed income and would love to be happy and keep this Jeep grand cheroee but, I can no longer take this chance. I would love to know how many people must die or how many accidents have to happen before Chrysler wakes up and recalls, I'm guessing they don't really know what to fix. I also had problems with my tail lights and had repairs several time, when I got a ticket after it was already fixed a few times I had to pay. Failed NJ inspection 1 time due to what they called a wig wag, which Jeep are know for, who out there is on the consumers side, no one it appears. No recalls on this this but, they will get back to me on a passenger restraint module, maybe next year 2016, if we are lucky. All 4 times the vehicle was being driven and the only thing that worked was shutting off the engine using the key. My vehicle must be safe for grandchild.

While driving the vehicle experienced a power loss except for the electrical system. I was unable to control my speed and lost power steering. After 5 seconds, while coasting to a stop, the vehicle resumed full power. Since the first occurrence, it has become more frequent (up to twice a week). In addition, the vehicle will not start randomly and requires a few minutes wait time before a successful start.

Grand Cherokee 6-cyl

  • 234,200 miles
(relating to the driver-side seat only) my daughter and I was waiting at a traffic stop, (I was driving) when the light turn green I pressed on the accelerator and my entire seat including myself swung back. Because of the backward momentum, it causes me to abruptly press further on the accelerator. I was able to regain control of the vehicle and pull on the side to inspect the seat. I found that the two front brackets under the seat had broken off. Since I had adjustable power seat, I lower the seat to align the broken brackets to wedge under the bar causing the seat to stabilize or at least hold in a semi-solid position. I called Chrysler and they said they could not do anything about it since the vehicle was out of warranty. I argued that this is an unusual incident where I have never heard that the driver-side seat brackets would break off and possibly cause an accident. Especially for a Jeep, this vehicle is meant to be driven on and off road. Again, they said that there was nothing that they could do. This is a design flaw and should be address before someone gets seriously injured.

This is horrible and I was scared. But I was driving slowly up my street and it started to race, I was trying to brake as I turned in my parking space my car was still racing and wouldn't brake and I ended up driving into my property, it seemed to accelerate as I kept braking and up the steps the car went and the car then stopped inches from my door. It was racing as I was braking and it would stop not until it hit the porch step. It was horrible, this car has never launched like a rocket. It was like it magically accelerated. I have had this car for years and keep it maintained. I see there have been recalls about this, why did I not get a card. I am glad I or anybody did not get hurt. Jeep is in shop.

Grand Cherokee

  • 98,000 miles
There are two issues, one being the issue with the engine dying once the vehicle is put into a forward or reverse position from either reverse or drive position. Second is the issue of the vehicle surging forward just prior to stopping. The engine will rev up just prior to stopping and start a hard but load rumbling due to the brakes being held and the vehicle wanting to drive forward. I have an appointment with my repair shop to diagnose the issue, and it is very wearing of the possibility of this issue causing an accident.

Grand Cherokee

While parallel parking, with my right foot on the brake pedal, I shifted the automatic transmission out of reverse. Immediately the engine rapidly revved up and lurched forward. I pressed more firmly on the brake, causing the car (a 2004 Jeep Grand Cherokee) and motor to pause, then the motor rapidly revved up again, overcoming braking. Horrified, and unable to stop the car, I watched as the car raced into the vehicle ahead of me. Immediately after the impact, the engine returned to normal idle. I then checked the car: Cruise control was off, my hands were still gripping the steering wheel in order to provide additional leverage for my foot on the brake pedal, my right foot was still firmly in the middle of the brake pedal and not near the accelerator pedal, and the gear shift lever was in neutral. The vehicle ahead of me sustained damage to its bumper and tailgate. This is the 4th time this has happened with this vehicle, the first two of which were reported to you earlier. In all three earlier cases, I was able to barely avoid an accident, but not this time. As noted earlier, the Jeep mechanic was not able to find any causative problem.
