03 CTS engine problems at 40K by lora1985

I loved my '03 CTS when I first bought it a little over a year ago. I bought it from a certified dealer and it still had a warranty, only for about 2,000 miles, but I'll take what I can get.
This past weekend I had gone away with a rental and on Monday when I went to take my car to work the engine was making a strange clicking sound and idling higher than normal. I had to take my more reliable 1993 Ford Explorer to work that morning. I had my mechanic come over and look at it, since I did not want to move it and he is saying the it is in the top of the engine. Now, I drive my car less than 12,000 miles per year, to work 15 minutes away 3 days a week and store it in the winter (it was to go in storage this weekend). I have done all my oil changes on time, get tune ups and have the entire vehicle checked over every few months. I cannot believe that there is an engine problem. Now I have to worry about whether this is even covered under the 8 yr powertrain warranty that is still on the car. Anyone else ever have this problem? You'd think when you pay so much for a vehicle, it would last a little longer than 40,000 miles....needless to say, after it is fixed, it will be gone. Cadillac is no longer on my list of reliable vehicles.

My Mother has a 02-03? CTS and when you turn the key over all you get is a small clicking sound....no starter clicking, dimming lights or anything. All of the electical seems to still work. I just want to save my Mom some cash and time if it is something I could take care of myself...any help would be great.

oil consumption by fscarano

A dealer told me, that using synthetic oil in my 04 cts is the cause of my oil consumption. They recommended I switch to conventional. Is this crazy?
 
I consuming about 1/2 quart every 3200mi
 2004 cts with 84.345 miles.

If the CTS owners manual reads like the DTS, it says to follow the oil life monitor but REGARDLESS of what it says, change the oil once year. Sounds like negligence plain and simple.

2008 CTS Engine OIl Consumption by jgaffney1

Just a blurb to watch your oil consumption. I have a 1 month old 2008 CTS DI with 2300 miles. Bought it November 19th, 2008. I've been watching the oil consumption.
 
The first two weeks it was exactly where it should be on the stick from the factory. Never moved.....I checked it several times in my garage in early December it was still very much on the stick in the center. I haven't checked it again until last night (almost 30 days later) and found the stick to be dry. It took almost 2 quarts to bring it back onto the stick in the center of the stick.
 
I'll attribute that to "breaking in"...but for those of you who choose to wait to check your oil until the change oil light comes on..........I wouldn't do that!!
 
One characteristic of the 2008 Oil gauge is that it always seems to peg out on 80 PSI when under load....it still did that even being 2 quarts low....kinda misleading. You would think pressure would go down as oil level went down. It didn't. I'd recommend you watch the oil in this new car as it breaks in.

Hi, I am planning on buying a 2008 CTS, can you give me an update on your oil issue?

You may have a leak on the engine. It happened to my 3.5 liter, they put a flourescent dye into the oil and after 900 km later pinpointed the leak.
   If the worst happens ,the engine expires while under warranty , you will get a new ,latest version of DI 3.6. Don't worry just keep an eye on the oil level and keep GM notified.
