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.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety.

While using cruise control speed increased and would not respond to shutting off speed control or by hitting the brakes car could not be stopped only pushing in clutch while the engine raced uncontrollably and pulling off the interstate onto side of road turning off key stopped this. When started back up engine still racing. Same thing happened about seven years ago never used speed control again until this

problem #6

Wrangler 4WD 4-cyl

  • Automatic transmission
  • 97,061 miles
I was approaching a red light and approximately 3 car lengths away from the vehicle already stopped at the light I began braking and heard a noise under the floor board and while pushing the brake pedal all the way down and the braking system did not slow or stop the vehicle at all. I lifted the brake pedal from the floor and reapplied it and the vehicle did not slow down or stop until it ran into the back of the other vehicle. Upon impact the vehicle began to idle up really high as if it were trying to drive itself. I took my foot off the break pedal and after I placed the vehicle in park and pulled the emergency break the vehicle stopped idling up high.

: the contact stated the following components failed intermittently, the airbag light illuminated, the speedometer and the tachometer showed no reading. The vehicle does not have to be in motion for the problem to occur. The contact believes the problem may be related to the clock spring, although the vehicle has not been inspected by a local dealer. The turn siganl would not cnacel, the dealer repalced the turn signal switch. Uypdated 03/28/06.

problem #4

Wrangler 4WD 6-cyl

  • Manual transmission
  • 78,000 miles
Vehicle was experiencing an erratic instrument cluster, and air bag light operation. Intermittently while driving instrument cluster, speedometer and tachometer rolled back to zero, and the air bag warning light came on. Also, at 82,000 miles left turn signal engaged when the brake pedal was depressed, and at 78,000 miles when driver's side door was opened while the truck was still running the defroster light came on. Dealership had not been contacted. Consumer took vehicle to two Jeep dealers and said that they're aware of the problem and many customers have experienced the same problem. Also, they said that it was a defective electrical connector.

I was approaching a stop light, two cars were already at full stop, I applied the brakes and my car came to a complete stop approxametely 10 feet behind the car in front of me. All the sudden my engine started like my foot is on gas instead of the brakes, I pushed on the breaks as hard as I can without any response, I hit the car in front of me. This is the first time that it happen. I drove the car this afternoon, it is driving fine. I went to a parking lot and I applied the breaks then pushed gas at the same time, the car did not move. My breaks are fine. I don't know what happen and why it happened, but I know for a fact that my breaks ewre fully applied, and the car was at a complete stop before it moved on its own. Skid marks were visible, but the car kept moving.
