Replying to: dbieganski (Apr 01, 2008 12:32 pm) I also have a CTS (2004) with a 3.6l motor. I experience the exact same symptoms as the original poster. I started the car one day and it made a strange noise, went to check the oil and it wasn't on the stick. I put 2 quarts in and took it to the dealer. The dealer says they cannot find an oil leak. It also uses coolant, well it goes somewhere. The GM Dealer claims that they searched the database and nobody has this problem. However a simple google search will show you that these 3.6l motors have problems with oil usage. So the dealer says they don't know what is wrong. I inspected the motor and found a minor leak on the rear main seal, but not enough to justify using 2-3 quarts of oil. The rear end also hums like some other people mentioned. I bought this car used with 20k miles on it and started to experience trouble within the first year. It now has 70k miles on it (long highway drives for work) and I am SOL because there was no warranty. I would not recommend buying a 3.6l first generation cts. Use a search engine and you will find a ton of results for oil usage.

My 2002 Seville used about 1 quart of synthetic oil every 2000 miles. The oil monitor requested oil changes every 10000 miles, so I added about 4 quarts in between changes. My 2007 SRX, with the RWD VVT northstar V8, has been much better on oil, needing none before the first oil change done  11,500 miles. The V6 is a different engine though.

| I want to replace the woofer on my 05 CTS. It sounds very distorted when the radio volume is turned up. I would also like to add navigation as well. I have found a factory nav unit and hopefully it is compatible and will work with my 05 CTS. | |

Replying to: sls002 (Apr 06, 2008 8:28 am) No. I would say about every 2500-3000 miles the car will be 2-3 quarts low. I am still having problems using oil and coolant and of course the dealer doesn't think anything is wrong. Now I am thinking that i have a gasket problem (intake or heads). As soon as I can get something else to drive for awhile we are going to tear into it. The rear end on the car hums pretty loud at high way speeds also. I thought it may have been the tires, but I got new tires and still humming. To be honest I think the car has a mind of it's own. Some days it doesn't want to idle right. I have to turn it off and back on and it idles (this is very rare). Also about tow weeks ago I back out of the drive way, put the car in drive and the car would not go anywhere. The screen displayed "stability system engaged" and I could only go about 4mph with the whole car vibrating. It seems like the traction/stability system was stuck on. I turn the car off and back on and it was fine since then. I give it another month and something else will decide to act up.

I have a CTS 2005 with 44,000 miles and I just had to have the rear end replaced. Has anyone had a problem like this and should I get an extended warranty for the next 3 years or should I get rid of this car now?? I can't believe this has happened with such low mileage. Any advice or info would be much appreciated. thanks Cher11

Replying to: cher11 (Aug 27, 2008 4:54 pm) an extended warranty on a 4 MY car with 44K would be expensive..if you could find an aftermarket plan...most are not worth it.....getting rid of the car for another is a financial decision.....at this point have you had any other problems with the car...did you pay for the diff or was it under warranty???

ConsumerReports, TrueDelta, and Edmunds all seem to demonstrated average to below average reliability on the CTS. What is your experience with 08 and 09 CTS? (good or bad). I know it's not very scientific - but informative non the less. |
