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 6-cyl

  • 114,000 miles
While stopped at a traffic light my Jeep started to accelerate and, even with the brake pedal fully depressed, surged forward. This has happened numerous times in the past week both at traffic lights and at stop signs, always while stopped. The rpms have increased to between 1,500 and 4,500. The Jeep dealer attempted to fix it on Tuesday, however the problem re-occurred on my way home and again with a mechanic in the vehicle when I brought it back. To date, the car is still at the dealer and has not been fixed.

2003 Jeep Grand Cherokee stalls when idling at stop lights, it also nears stalling and then lunges forward when idling. I was stuck in the center lane during rush hour traffic last evening with my 2yo in the back seat when my Jeep stalled. This is not an uncommon occurrence, it has happened every day for the last month. This is a very serious and dangerous situation; it makes you feel as if you have no control over your vehicle! I am taking it to the dealership on sat, but from complaints I have read on comsumeraffiars.com I am not expecting them to be able to do anything. I have already contacted Jeep and even though there are recalls for certain models for the exact same problem my VIN doesn't match up to be able to do anything about it.

  • 88,442 miles
The contact owns a 2003 Jeep Grand Cherokee. The contact stated that the vehicle stalls and the RPM's begin to rise suddenly. The vehicle does not backfire, jerk, or make noises. The failure occurs while driving at any speed. The contact must activate the hazard lights and restart the engine. Usually, the vehicle restarts, but sometimes it takes 3 or 4 attempts to restart. The dealer replaced the crankshaft position sensor, which remedied the issue for a few hours. The failure recurred the same day she retrieved the vehicle from the dealer. The contact is scheduled to take the vehicle back to the dealer, but just wants the defect to be corrected properly. She researched the failure and found numerous complaints for the issue. She believes a recall should be issued for the defect. The current and failure mileages were 88,442.

Car stalls while running. This happens mostly on low gear but also has happened while on the highway. This is a serious hazard to the extent I do not want my children in this vehicle. Do not know what to do as I see on the web many complaints of this nature.

Consumer states: Vehicle cuts off while going down the highway, no warning, doing almost 70 mph. Nothing worked, and there were no brakes. The only thing working was the 4-way flashers. Tried to turn steering wheel and lost power steering. Another time went to turn in the position the wheels were and in that was the way the vehicle went. The repair shop mechanic said it needed a crank sensor. Previously, before they put in a fuse and it blew out.

  • Automatic transmission
  • 4,000 miles
I took my vehicle in for the routine oil change at the dealership I purchase the vehicle. After that day, the vehicle vibrates to the point you cannot play a cd. They are telling me this is how the vehicle performs. I have been to the dealership many times with the same response. I also have taken it to other Chrysler dealership with the same answer, it seems that the answer is the same after they look at the repair history. I also have met with the Chrysler marketing rep twice, and the dealership told me that the Chrysler technical rep drove the vehicle. Yet when I requested a encounter with him they declaim and said there is no technical rep. I also met with the general manager from the dealership twice, sales manager many times, I need this to be look into because I think my vehicle was tampered with, because if it was running like this when I bought it I would have not bought it. The vibration is getting worst. I do have a extended warranty, that I cannot use because they refuse to even look at the vehicle. Their solution was to sell me another vehicle, which I declined because they wanted more money down. Why should I buy another vehicle when I have a new one that they destroyed.
