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.

The contact owns a 1998 Cadillac Deville. The contact stated that while driving approximately 65 mph, the cruise control would not disengage. The brake pedal was then engaged, but the vehicle hesitated and would not stop. After approximately two miles, the cruise control eventually disengaged and the vehicle came to a stop. There was a recall under NHTSA campaign id number 97V183000 (vehicle speed control) that may be related to the failure, but the manufacturer stated that the VIN was not included. The vehicle was not repaired. The approximate failure mileage was 170,000.

Problems with 1998 Cadillac Deville cruise control system. When consumer applied while vehicle was in cruise control, it didn't disengage. Consumer switched cruise control off, but it still failed to disengage. Thus turning off the engine. Consumer then restarted the vehicle and without warning accelerated on its own.

problem #2

Feb 031999

DeVille

  • miles
When engine is started, both when cold and hot, in all gear selector positions, and an attempt is made to depress the accelerator pedal, the pedal will nor depress normally. To depress the pedal, a moderate force is required. When this is done, the pedal linkage then makes a "snapping sound" and the pedal then advances suddenly, causing the engine RPM to race. If the car is in any gear when this is done (drive or reverse), the vehicle will then either lurch forward or in reverse. The dealer serviced this problem for the first time on Feb 6, 1999, at which time they diagnosed the cause as foreign material and replaced the J5490 body unit, throttle. This solved the problem for approximately one month. In March 1999, the condition reappeared, and the dealer replaced the J5330 cable, accelerator control. This repair solved the problem for six weeks. During the week of 19 April 1999, the condition reappeared. I believe this is a serious safety issue. I talked to the dealer's service department to schedule follow-on maintenance on April 29. I asked themif this was a common problem, and they confirmed that it appeared to be, based on the numbers of 1996-1998 cars they were seeing with similar conditions.
