#55 of 64 Re: 2004 CTS 3.6 Engine Failure [jfdcustom] by unhappycanuck Mar 31, 2009 (10:12 pm)
Replying to: jfdcustom (Dec 22, 2006 11:35 pm) I have a very similiar problem. I have a 2006 CTS 2.8L with 44k KM's on it. The car was last in for an oil change in Aug of 08, since then I put on 6000 KM's. The middle of February as I was driving the car to work I started to hear a faint clicking noise coming from the engine, at first I thought maybe the air dam had fallen down again. After work I was driving home and about 3 blocks from the house (this is only a 33km trip each way) the clicking got louder and the car stalled so I took it to the dealership right around the corner from the house. No warning lights on the dash lit up, no engine light, nothing. I got a call from the service tech saying that the engine had no oil and that GM hadn't ruled out warranty coverage but they weren't going to cover it out of hand, and that I would have to pay a diagnostic charge to find out what was wrong with the engine, so I agreed, they tore the engine apart and my service tech told me that there was a defect and the engine had significant oil blow by, but GM refused to cover it. Meanwhile No oil low light came on, no engine light came on, and that was the first day that the engine had made any noise. They refused to cover it saying that the car should have been in distress for days prior to me bringing it, and that I obviously wasn't checking the oil each and every fill up. I started dealing with their customer care centre and now the story is changing again, they aren't covering it because there is apparently no defect, and that the engine was out of oil and it was my responsiblity to check it each time I filled up the tank. My service tech also told me they had another 2006 CTS in a couple months earlier with the same problem but GM covered that one. I don't know where to go from here, they want $15,000 to replace the engine. The car isn't even worth that! I'll never own another GM again, maybe they need to go into bankruptcy to come out a better company. Replies to this message: natalia3 (Sep 24, 2009 12:43 pm)

Replying to: ctsguy2 (Jan 08, 2009 10:34 am) I have an 09 CTS direct injection AWD that flutters everytime the engine is stated after sitting for a few hours. It is most apparent in gear and goes away about the time the engine comes off high idle, or within 10-15 seconds. The dealer has witnessed the problem and added a can of injection cleaner which has had no affect so far. That was about 400 miles ago.
#57 of 64 2007 CTS Oil Consumption by prettypackage2 Aug 07, 2009 (12:42 pm)
I have a 2007 CTS with 31,000 miles, and, I did not see oil usage until my 4th oil change, my sensor light never came on and my car felt like transmission problems. I had to make a appointment with the dealer and the mechanic called me and was upset with me like I am a dumb girl, I grew up with mechanics. Told me I had no oil in the car, exp I had an oil change and was not due for another, also asked why the oil sensor did not come on, he stated there was not one. I told him if this new car uses oil like this why would the company not put an oil sensor on the vehicle. He acted like this was an isolated incident. Of course, I had to have my spouse call, I can't deal with Mechanics that think all women are dumb when it comes to cars, especially when he stated oil changes are to be done every 3000 miles and I told him that is not what the manual states. He did an oil change and now I am within a 1000 miles due for another oil change and my oil is low again. He wants me to come in once a month for a consumption oil test, I told them they are nuts some of us work real jobs and everyone who owns a Cadillac is not always available during their work schedule, My dealers hours our 8-5 M-F. This is my first Cadillac and american car, I ask myself many times when I have have a problem with this car why did I get one now!

#61 of 64 06 cts by mymymy Oct 12, 2009 (11:21 pm)
Has anyone had problem with '06 cts over heating--coolant was in the car? Without warning the car over heated, causing problem to the radiator and the transmission. Dealer estimated will costs over $6,000 to replace both.

Replying to: angelmarie415 (Mar 05, 2008 9:19 am) Same thing happened to me today. Exactly. Can you tell me what the diagnosis and repair was? Replies to this message: mymymy (Oct 25, 2009 2:42 pm)

Replying to: wilsoncts (Oct 23, 2009 8:15 pm) wilsoncts: Turns out the over heating caused major damage to the radiator, which caused a crack to the "wall" (my word) between the transmission and radiator. Thus coolant fluids got into the tranmission fluid which caused the car to almost literally stop moving.   Part of the repair was to replace the radiator and drain the tranmission of the contaminated fluids, which looked like thin mud). A solvant was used in the transmission to help clean out contaminated fluids. Fluids were put in the transmission and the new radiator.   The recommended mechanic didn't find exactly what caused the car to overheat,
#64 of 64 Timing Chain by stu8me Nov 06, 2009 (7:18 pm)
Just recently bought an 05 CTS. After a month of owning the car I had to take it to the dealership for engine issues, it was the timing chain. After a month, fixed, I continued on my routine. 2 months later same problem, timing chain. Brought it back even more upset, fixed in a month and now I have it back again. Issues are arising in it again. My guess is an issue with cam shaft or the main berring. The only way this would have been an issue is if the car was flooded prior to me buying, which dealer provided me with clean carfax.....can anyone help me out on this?   thanks
