This thread is very interesting. I bought a 3.6L 2005 CTS brand new off the lot. I kept the oil changed in it at the dealer when the OLM system said until the dealer went out of business and the after that I did the oil changes at a local mechanic using Mobil 1 as suggested in the manual. I started to notice that the car was using about 1 quart of oil every 4 - 5000 miles. I spoke with a Cadillac dealer and they said this was not unusual. Then at around 75000 miles in 2008, and out of warranty it began misfiring on the way home from work and by the time I had made it home the engine was misfiring really bad and knocking really bad but no trouble light. When I was pulling into the driveway the check engine light finally came on and the oil level low warning came up. When checked the oil it was empty. Ihad checked it the previous day and it was full. I had my mechanic tow it to his shop and he found that the timing belt had jumped and bent 11 valves. I contacted Cadillac and they told me that because of the age of the vehicle and the mileage there was noting they would do. Still owing money on the car I spent the $5000 and had the valve train replaced.
The care ran fine for about 1 year until late last it developed a knock in the lower part of the motor. I was right back to where I started from except this time it needed a new motor and still being in debt up to my eyeballs from the last repair I called around and found a mechanic that put a used motor in it for $3000.
The bottom line is that my dream car became a nightmare. I will never get my money back on this car. A car that was $32K new has now cost me over $40k. DO NOT BY A CADILLAC!
#105 of 721 '05 CTS oil problems
Jun 09, 2010 (4:06 pm)
84K miles, changed oil and filter every 6K miles, used mobile 1, never had oil consumption problem between oil changes (yes I checked oil level approximately once a month) oil or engine light never came on, oil life 72%. Never any sign of oil leak or fluid on garage floor. Heard slight knock, had recently changed from Chevron to Costco gas, assumed I had water in gas, talked to mechanic said to get additive and run gas tank to near empty. Did this, knock went away. 2 days later car started knocking very loud, had car towed to mechanic, mechanic said there was no oil in car. Engine blown, replacement $8K to $10K. Seems like I am not alone?

I had an '05 CTS that I bought new and that I sold to a friend of mine. Then I bought a new '09 last January. My first CTS has 49,000 miles so I can't verify what will happen with the engine. When I bought the '05, the dealer told me to follow the OLM. I would change the oil 7 to 8,000 miles. The dealer now tells me that I need to change the oil every 6,000 miles in the '09, which I am doing. He said that they had found that the actuators in the engine were going bad at around 50,000 from going too far between oil changes. One of my friends bought an '05 CTS which was used. He did not have it one year until the engine went out and had to be replaced. Luckily, he had bought one that was certified and Cadillac paid for it. The '09 is a dream to drive, but I only have 11,000 miles and I can't know what kind of service I will get. I am so sorry for the two of you and what you have had to spend. What I wish I knew, was how widespread this problem is.

According to Consumer Reports, the CTS engine reliability has been better than average to much better than average except for the first model year (2003), which was worse than average. 2003-05 models have had problems with the cooling system (thrmostate, water pump), but the engine overall appears to be quite sound.
So, these problems appear to be anomalies.

It is interesting about the cooling system. My '05 had to have a water pump at 48,000.
#110 of 721 28k mile timing chain break - really!
Jun 12, 2010 (6:09 pm)
Sat., June 5, 2010 our bought new 2007 CTS 3.2 with 28,000 (28k) miles shut off while approaching an intersection here in Ft. Lauderdale. No restart, very loud grinding when the key was turned. With help, pushed it into a gas station. The Cadillac service suv arrived and Israel did exactly what I did - checked the oil then turned the key. Loud grinding. Called a tow truck, driver turned the key again - same thing. Tuesday Bayview Cadillac told us the timing chain had let go, and they were going to replace it. Checked the internet and saw it was an interference engine. Told service writer I did not want a repair, I wanted a new engine.He referred me to the service manager who said if there is other damage we'll fix it, like replacing the heads. I said no, you won't, I did not buy a used car and do not want a rebuilt engine in a 28k mile car. We want a new engine. He said it had to go through the general manager to GM, so he was to call me. I never spoke with him. A day or so later called the service writer, who told me the valve train had indeed been damaged. I repeated to him do not repair that engine, I want a new one. Stopped into Bayview Cadillac Friday afternoon, to find the engine had been repaired and the set of heads and a pile of parts on the floor. Danny the service manager lied to my face and said you never told me not to fix the car. I repeated our previous conversation and he did not deny this. Now the general manager is there and I told him I did not authorize this repair, in fact we have signed nothing since the car was brought in. His reply was you start paying for the rental car tomorrow. I left the car there and called the GM 800 number to begin a case. HEY CADILLAC, I DO NOT WANT A REBUILT MOTOR IN A 28K CAR, ARE YOU DUCKING A RECALL? And to you, Mariah, how can you deny and GM deny these CTS engines are defective? Come to Ft. Lauderdale, to Bayview, and I will show you a 28,000 mile car with a rebuilt engine I am not accepting. Anyone who considers buying a GM car after reading these horror stories is loco.

One of the things that interests me is how gm has customer service people intercepting solvable problems but ignoring this pink elephant . One of them said they would look into my engine problem but never got back to me . Now I am willing to spend some money to do a couple of commercials with a toll-free number to see how many people had this problem . I had this exact problem and will soon see how many people the gm service advisors manipulated the warranties for to stop the number of complaints from rising . This seems to fit deceptive trade practices in my opinion . I put my car in storage and am willing to follow this to the end as gmac still expects me to make the $600.00 monthly payment.

It's pretty obvious there is a problem here, but it appears they are just going to sweep it under the rug. When my motor went they said they would not do anything for me "based on the age and mileage of the car." So apparently their cars are only design to last 75,000 miles or so. Granted the car was 25,000 miles out of warranty but back in the early 90's I had a Dodge that had 210,000 miles on it when I traded it in and it still ran great and never burned oil.

After parking my car in the driveway (my driveway is slighly inclined) for about 24 hours my car has a lot of trouble starting. My car will start after about 5-10 minutes of cranking it over but then it runs very rough at first. The only time I have this problem is when I park my car in the driveway. 99% of the time, my car is parked in the garage on a level surface and I have no issues starting the car. In the colder months, I can park my car ouside in the driveway 2 days before it has the "no start" issue but when the temp is mild, the problem happens within 24 hours. Yes, my gas tank was full of gas. Any clues why this is happening? My car has 58K but it has been happening for over a year now. To avoid the issue I park my car in the garage.
