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.

While returning from a trip, the engine shut off and all the power in the car was gone, while driving (in motion). We had been driving approximately 1.5hrs. We were going about 65mph, when the radio and ac went off. There was a message that said something about "battery reserve" ("???") I turned the radio and air back on. Immediately after, "service brake assist" message, then entire dashboard (including speedometer) goes dead. Car shuts off and immediately decelerates. Fortunately, we were in the slow lane already and could get out of quickly moving traffic (and the cars behind us could swerve into the other lane to avoid hitting us). On the side of the road, all power was still lost and could not remove the key from ignition. Attempted to "jump off", which restored power to remove the key. But vehicle would not start and ultimately had it towed. Dealer said motor was locked but didn't know (or immediately care) why. After I prodded the service manager, the technician called to say it was the alternator belt that was locked, causing the motor to be locked. With all of the ignition switch issues that I have read about the last 2 days, I am concerned that neither of those are the cause, but a result. My key "fix" lasted about 2 days. Although mentioned, the key was not "fixed" on the next visit.

During the winter February 2015 I walked out of my residence, went to start my vehicle & it would not turn over. I accounted the issue as to the weather being below zero temperature. A few days later, when the temperatures were higher the vehicle still would not start. The day before the Cts like not start, I noticed it was driving a little sluggish that evening when I drove to the bank. I just had a tune up done on the vehicle two months prior and never had any problems prior. I arranged for the vehicle to be towed to the holman Cadillac dealer in my area and received the diagnostics report. Upon tear down, they found all four cam shafts okay but crank gear is off 5 teeth due to primary chain tensioner wear which caused slack in chain and allowed gear to jump time. I enclosed the document from them in the complaint.

I was driving the vehicle and was hit from behind and went into a curb. My airbags did not deploy and the car would not restart. The engine completely shut off. The car continue to have problems with the engine and smoking after it was repaired by a GM dealer. We had to turn the car in and file bankruptcy after it stopped working.

On 07/26/2015 went to start car. It started ok, but then there was no power to dash non on my indicators came on, when I went to put the car in drive the gear shift would not move. So I went to turn the car off, at this point the key would not turn all the way to full off position and is stuck in the ignition, all night. This of course means the alarm would not go on. So key stuck in ignition, no alarm, no dash power. This of course by morning had killed a new battery of only 5 days old.

2006 Cadillac dts. Consumer writes in regards to vehicle engine issues. The consumer was informed there were two pans under the engine that were leaking oil and the gaskets needed to be replaced. Only the small pan was replaced. Two weeks ago, the consumer noticed oil spots on the garage floor. The dealer informed the consumer it would cost $3,000 to repair the vehicle.

I am the owner of a 2006 Cadillac Cts 3.6L V6 with a broken timing chain which is a $1,500 repair. I was traveling 70 mph down the highway when the timing chain went out and almost had an accident trying to pull onto the side of the road. I contacted GM and was told that even though my vehicle has the same engine as the 2007 model, it was not covered by the extended warranty. Upon researching this is a known issue with the Cadillac Cts from the very beginning of its appearance in 2003. The number of complaints from 2003 to 2006 for the timing chain on the nhtfs website was the same as the number of complaints in the years covered by GM¿'s special extended warranty (GM subject 10287 concerning timing chain issue) for the 2007-2009 Cts. GM realized the timing belts were an issue and found a way to only cover those 3 years by blaming the need to reprogram engine control module. By doing this they managed to prevent investigations by the nhtfs regarding the timing chain issue. While the engine control module may have contributed to the timing chain issue in the 2007 ¿¿ 2009 years, it is not the cause of the issue since the problem existed in the 4 years prior to the addition of the faulty engine control module. The years following the extended warranty there have been zero complaints related to timing chain issues. This indicates that perhaps the timing chains being used previously were likely replaced, but I do not have the resources to investigate that. The nhtfs has never investigated the timing chain problem in the 7 years it was occurring. Part of the problem is that most people filing a complaint about a timing chain don¿¿T know how to categorize it (I found instances under airbags, electrical, etc.) these are only the cases that have been reported to the nhtfs, but the internet is filled with people complaining about the problem.

Check engine light came on and the Cadillac dealer as well as two independent shops gave the same diagnosis -- the timing chains [3] had evidently 'stretched' -- no recall, no warranty -- only $1,500 out of my pocket -- who ever heard of such a dumb thing, this is not a Toyota with timing belts -- I am truly disgusted, that's the end of Cadillac for me --
