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 driving down the road there was an oil leak and vehicle lost about 7 quarts of oil. This got all over the motor, muffler, and the road. There was a strong burning smell, but did not catch on fire. Mechanic told consumer that was the oil pressure sensor. Has not yet been repaired, but the whole engine will need replacement. For new engine and clean up it would cost $8,400.

The ABS traction control was not working and the dealer was unable to resolve the problem. The vehicle has been in and out of this dealer repair shop for this problem since Aug. 2002 and the intermittent problem with brake failures and extended braking distance keep recurring. Anntena stuck up. Power antenna assembly replaced. Oil level low and oil light is on. There was no reading on the dipstick. Had to add two quarts of oil after driving 1500 miles. Oil life indicator was reset. Piston, rod and oil rings replaced. Drivers side headlight cover fell off with bulb burnt out. Headlamp housing assembly replaced. Consumer went to start vehicle and it wouldn't start. Battery replaced. Catalytic converter rattling. Drivers side heated seat/switch inoperative. While giving gas hesitates; struggles up a hill. Spark plug wire replaced. Notification by postcard. Ordered parts. Drivers side window won't go up. Replaced left door window switch. Ses light on. Exhaust recirculation valve (egr) replaced. Transmission makes a grinding noise on fast acceleration. Dealer found the exhaust pipe at the rear of the converter shifting a cross brace when accelerating. Rearview mirror broke off base.

In 2001, the right headlight lens on my 1998 Cadillac Deville fell off. The dealer, heritage Cadillac, replaced the headlight assembly at no cost, since the car was still under warranty. On 11/6/04, the left headlight assembly fell off. I have not yet discussed the problem with the dealer.

When the traction light flickered on/off. The cruise control and brake lights failed. Which almost caused an accident.

DeVille 8-cyl

  • Automatic transmission
  • 53,300 miles
In April 2001, at 37,000 miles, air condition/heat fan motor failed and was replaced (under warranty) by a dealer. Again in April, 2003, at 53,300 miles, local dealer says motor is defective and needs to replaced at cost of $420. Attitude of dealer and Cadillac customer service is that "stuff happens". my belief is this failure rate indicates problem with quality of fan motor or problem with motor electrical circuit.
