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.

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.

Air bag light constantly stays on, along with the check engine light. Seat belt chime constantly rings with the seat belt connected. Gas low notification light does not come on until on empty. No heated seats. I think the ECM needs to be reset.sun roof goes up but not slides open. Passenger side door won't open.automatic car starter doesn't work. 2 years ago, my son in law, started this car in below zero temp and it started on fire. He put it out and restarted it and it was ok. Something makes noise occasionally for no apparent reason.

4/14 - car was shutting off intermittently, pulled over in hotel parking lot and a gentlemen came up to car to tell me that it was smoking, got out and there was a fire at the rear of the car. Ran into hotel and got fire extinguisher to put it out, had towed to repair shop. There determined that the terminal on the top of the fuel pump over heated and melted a hole in the top of the pump, causing fuel to leak out and catch fire -$6000 worth of damage, only used parts available to fix car. 8/14 recall was released about fuel module and harness. 6/15 - called dealer about unrelated issue (door lock), VIN# was ran and was told parts were available to fix recall. I mentioned I did not receive the letter that parts were available and was told dealer had to order them, 4 days later parts came in and work was scheduled. Car was there for 10 days "having trouble getting parts". when car was picked up the fuel gauge was now off only reading 3/4 when full and check engine light on. Told harness is not available to finish recall and it will take care of both problems. This safety recall is beyond a reasonable amount of time for repair. The dealer should not have torn into car if all parts were not available. Car is due for inspection 9/15 and as it currently stands it will not pass inspection due to the check engine light being on and now the gas gauge does not read at all. This has been a huge inconvenience and am very displeased with the lack of support from Cadillac and the dealership. I now have a vehicle that I can not get parts to fix recall, will not pass inspection, and I can not sell it or trade it in.

I am a mechanic and have worked on numerous vehicles recently that are model 2006 Cadillac Sts. Safer car.gov needs to make engineers aware that this car is a death trap. GM should have this vehicle added to the ignition recall list. It makes no sense to me a mechanic that GM has models cts and dts but not the Sts on the recall list, especially since they are all the same car. It's not like the cars have a different ignition, they all come ofd the same assembly line and stamped a different model name for various pricing points and target markets. Please don't ignore my message as this is a very vital topic.

Traveling 81 North in northeast Pennsylvania, rounding turn car stalled. I lost complete control of the vehicle which caused me to slam into a guard rail and the car went down an embankment and into a boulder. Air bags never deployed. Passenger and I were severely injured and had to be pulled out of the vehicle. Although we were both buckled in, the seatbelts flew off upon impact. This car should be recalled, it is very dangerous and should not be on the road (its a death trap).

2006 Cadillac Sts. Consumer writes in regards to vehicle ignition problem. The consumer stated as he neared the highest elevation of the highway, other vehicles were going about 58-60 mph, and the crest flattened, the speed increased almost automatically, as the resistance deceased. After a few hundred yards, the consumer realized he had no power under his foot, the dash lights went out with no engine condition indicators displaying, the only light on the dash was a lighted "D" indicating the transmission was in drive. Despite the vehicle being in gear, the vehicle was coasting at 70 mph. Upon inspection, the start button and ignition switch failed. A few weeks earlier, the vehicle stalled while at a stop light. He immediately re-stared the vehicle. On a separate occasion, the consumer experienced a lapse of power.

  • 48,888 miles
After car had been immobile for a week, attempted to start and engine just clicked and car would not start. I placed the battery on charger without disconnecting from terminals, charge battery for approximately 10 hours. Tried to start vehicle again the next day. It started and I drove directly to an auto parts store (auto zone) and had them test my battery and alternator my system tested good, so I drove for a couple more days, this time I kept a close watch on the battery volts and they kept fluctuating up an down. I parked the car for another couple of days and the problem came back again. So I charged the battery again and then took it to a GM dealership and requested they troubleshoot it. They charged me $45 and told me everything was good. Now I have the car at home again with a dead battery.I need to find a solution to this un safe problem. The car can shut off at anytime and I won't E able to restart w/O a jump..has there been other complaints similar to mine ? help help!

Car stalled on busy street and would not restart. After later investigation it turns out that the electrical connector in fuel module assembly shorted out and melted the plastic connector. It also melted part of the bottom side of the top of module. GM has recalled earlier models of vehicles for the same situation. I believe this to be very dangerous for multiple reasons:stalling on busy street and not being able to restart, fuel leaks due to hole melting in module top, and its a fire hazard.

  • 72,000 miles
At approximately 72,000 miles my Cadillac's passenger seat light began to act up and would go on and off when someone would sit in the front passenger seat. I am single and rarely ever have a passenger in the front seat. Approximately two times per month someone rides in this seat. The last time someone sat in the front passenger seat, I traveled 10 miles round trip on 1/19/2012, the "service air bag" and air bag red light indicator came on the dash and since then will not go off. I take extraordinary care of my vehicle. I took it to a dealer only to be told that the entire passenger presence system (pps) needs to be replaced and that it was going to cost me $629. I understand that the same problem occurred in the Cadillac cts model of the same year. My question and complaint are: Did the modules come from the same place and/or are they the same module and passenger presence system. Why wouldn't my Cadillac Sts be included in that recall when I see that this has happened to so many other Cadillac Sts models of the same year.

  • 90,000 miles
Keyless door entry unlock fails. The outer handle has faulty wiring with many cars sent in for replacement and no recall performed yet. In this instance, the door lock failing can lock the driver in the car during an accident or fire and, if the person is unresponsive due to the accident, someone on the exterior of the car cannot enter through the drivers door. This poses a significant safety risk that has yet to be addressed. Through my research, it commonly affects 2005 & 2006 Cadillac Sts model cars with the keyless entry & keyless ignition.
