#45 of 64 Re: HESITATION OR SLIGHT STALLING WHILE DRIVING [150mphclub] by mrvr2u Oct 21, 2008 (6:31 pm)
Replying to: 150mphclub (Mar 24, 2008 3:58 pm) I have been taking it to the dealer since March and they still can't "duplicate" my concerns. I have even had them in the car the service advisor noticed the problem; however, the service manager couldn't "duplicate" my issue. It is with GM Headquarters as well as the Better Business Bureau.

Tell me something, if my 2006 cts has platinum plugs and they do not need to be changed until 120,000 miles and I am doing my oil changes on a regualar basis, what is the 30,000 miles maintenance check for?   Can anybody answer that one? Replies to this message: pao (Jan 09, 2009 12:38 pm)

I have an 09 CTS with the 3.6 direct injection engine and 1900 miles. At idle the engine has a flutter regardless if in park or in gear, that actually rocks the car. Is this common? Anyone else have this same issue or heard of it before? Replies to this message: phil83 (Aug 07, 2009 11:22 am)

Replying to: mrvr2u (Oct 21, 2008 6:33 pm) owners manual should state exactly what is checked during this check

Replying to: panzer (Jan 18, 2007 12:10 pm) My wife bought a 2005 CTS last year with only 28K on it and found out that it uses a quart of oil in 1000 -1200 miles and we where told that's normal usage. I've never owned a newish vehicle in which any usage was normal let alone noticable. We found this out when the low oil sensor wouldn't allow us to start it up once, it was down too low and we had the car towed. I was also under the belief that with synthetic oil we could go 5000 miles between oil changes , now if I'm wrong I'd like to know, but everyone I've talked to outside the dealership I bought the car from says between 5000 and 7000 miles using the recommended Mobil 10W30, we have the major extended service plan on this car for another 45K miles and the dealer will not even entertain seeing what could be done to stop it from useing the oil up so fast . Another ASME certified master mechanic friend of mine said there's been problems with these engine forever and it needs to be replaced. What do you think Replies to this message: pao (Mar 03, 2009 10:47 am) jenton (Mar 14, 2009 7:19 am)

Replying to: bwestz71 (Mar 02, 2009 10:06 am) unfortunately the early model 3.6 engines in the 04-06 MY CTS have the oil consumption issue as a common problem....not to all of them..but you obviously got one of them...   your assumption for synthetic oil change intervals is also good.....all my cars run it and use that range..to include my 09 CTS.....however if you are using oil you will unfortunately have to replace it....   try another dealer as well.....its a documented issue but I dont know if there is a fix....you might want to do more research on other cadillac forums Replies to this message: jenton (Mar 14, 2009 7:19 am)

#53 of 64 Engine Shut Down by unsettled Mar 29, 2009 (8:17 am)
We purchased a new 2009 CTS less than three weeks ago and and are at around 800 miles. Twice while driving on the highway the car completely shut down/off. This happened while driving on a busy highway. I was able to pull over and restart the car. Has anyone ever heard of this and have any idea why? The dealer did put us in a loaner until tommorow when the service dept reopens. Replies to this message: pao (Mar 30, 2009 6:05 am)

Replying to: unsettled (Mar 29, 2009 8:17 am) is yours a DI or non-DI engine, AWD or RWD?.....there has been one or two other instances of this mentioned on another cadillac forum....not sure what the solution was as I will have to look it up
