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.

Hello,     I purchased a 2006 Sts V8 last January. Since then I have had to replace all four tires immediately, a starter, and the brakes and then replace front brake pads again.  I recently went to auto shop and was told catalytic converter and suspension need to be replaced.      after investigation I realized there was recalls on the 2005 Sts V8 model for the  brakes, suspension and the catalytic converter has an extended warranty of 12 years and 200000 miles.   the fact is that further investigation showed my car was built in 2005 and the actual manufacture date on vehical was 6/20/2005 which was last date of production for the 05 model.  the 2006 manufacture or build date began on 6/23/05.  it seems odd all the recalls for the 05 model are all the year old vehicle are faced with.  I called Cadillac and they said although the build date of vehicle is valid the VIN number is what is followed.  however, further research shows they actually found the same recall on the 05 catalytic converter on a 2007 Cadillac.      everything points to the fact that the  my 2006 model was actually either a late model of a 2005 by the build date of 6/20/05 and or the same parts have been used as the 2005 recall.  lastly the VIN number when I pulled up on a site showed it was actually a cts model.   I have spent a lot of time and have a great deal of data I could share that would back that my 2006 Sts V8 actually is part of the recall cars.    I understand the VIN number is what is looked at but when model year cars are being made and sold as different years than when they are produced and recalls effect the year of actual build this becomes very concerning.  as in the past year I will be spending over 3000$ plus dollars to fix this car.    I.hope you can look into.  as  they wont even investigate or give me the serial numbers for the parts being recalled

This problem started over a year ago and I have had it to the dealer twice and they can no find the problem because there are no codes in the car. While driving the car it shuts down and you lose everthing lights, turn singles, hazards, the dash goes totaly out and the engine stops the best you can do it to pull it over to the side of the road and hope you don't get hit. I have had this happen it town driving and on the highway so it has nothing to do with speed. I have loaned my car to other people and it has happened to them so it is not the driver. I will happen and you pull over put the car in park and it starts right up and you can continue driving and it may happen a mile up the road or it may not happen for a week or a month later and still no codes.

I was traveling through the countryside on my way home from work. My car suddenly stalled, I lost control of the vehicle and slammed into an on coming car in the other lane. This caused permanent traumatic brain injury as our airbags never deployed causing us to slam our heads off windshield and side door window.

The fuel delivery system has been failing in the same manner that I have seen many other Cadillac owners have gotten repaired through a recall already in place. Every single time I put gas in the tank the car refuses to turn on with the first attempt. The only way to get the car to turn on is after multiple attempts and finally enough fuel gets delivered to the system. Similarly, the car will hesitate or feel like no gas is being delivered to the engine while driving on the highway. Often, it will cause a dramatic drop in speed causing a dangerous situation. GM definitely needs to take this into consideration because it is faults equipment rather than wear and tear. Also, there seems to be a some major issue with the oil system in the car. One week after a synthetic oil change, there is over 1 quart of oil missing in the reserve. There has been over 4 quarts missing at a time.

1) on interstate I-495 long island expwy, car moving slow came from on ramp straight across to middle lane. Went to accelerate to pass in left lane and engine stopped. Putted on emergency flashers and was able to pull into hov shoulder and restart engine. 2) on northern state pkwy (2 lanes only) on long island, NY and was in right lane- saw oncoming traffic merging ahead and went to give gas to move over to left lane and engine stopped. Again- moved to shoulder, restarted engine. 3) was doing 65 on njtpke I-95N in left lane between cars and trucks on right. Engine stopped (no acceleration- just straight driving). I was between vehicles and no place to pull over- put car into N and restarted and back to drive. This happened again- did same thing. When it was clear- pulled over to right shoulder- turned car off and restarted and continued trip. ** could this be part of the recent recall on caddys 2005-11 but did not include Sts's"??" just for the record- have new air filter and sprayed both the maf and throttle body valve with correct cleaners- recently- after seeing a video on caddy complaint forum.

The engine shut off when I was driving on a side street at 20 mph, and also shut off 5 times as I was driving on the highway at 65 mph. The cluster panel turned off, but the radio stayed on. The odometer showed a message engine control module (ECM). I pulled over, put the car in park, and restarted the vehicle each time. The Cadillac dealership said that rear axle pinion seal was the only recall for my Sts, but I am experiencing NHTSA campaign number: 06V020000, and NHTSA campaign number: 06V007000 also.
