#1 of 720 2004 CTS 3.6 Engine Failure
Dec 22, 2006 (11:35 pm)
I have a friend with a 2004 CTS 3.6 Sedan with under 30K on it. The car recently started making a lot of engine knocking and shacking a good bit. At first I thought it was maybe some bad gas, so I added some fuel system treatment along with some fuel stabilizer, that did not seem to work. Then, since it is usually driven in the city, I took it on the highway to clear it out. That seemed to do the trick, but only temporarely. Yesterday my friend started up the car in the morning and the front end and motor just shook horribly, so he shut it down and had it towed to a local Cadillac dealership. When it got to the dealership it would not start. Upon further analysis they determined that there was not any oil in the engine, they said they checked the dipstick and cylinders, nothing. Now, in all fairness, my friend did tell me that there is a possibility he has not changed the oil in the car in about 2 years, but I am not sure if the car just ran out of oil and it burned it up over 2 years or what. So, long story, the engine seized up, the codes that came up were errors concerning the camshaft and such. The only time the engine light came on or any warning for that matter was right when it was started the last time, when it was towed. In short he is looking at a new engine for about $8,000.00. Cadillac stated this is not under warranty because my friend did not maintain the car as he should have. The claim is in dispute with GM right now. Any ideas please post.

Sounds like you're the designated "car expert" in this little drama.
Did you check the oil when you were first asked about this? Was there any? If not, taking it out to "clear it out" at highway speeds probably finished off what was left of the engine.
Many automotive scenarios have an exponential piece to them. The car may have only used a half a quart of oil over 3000 miles, but toward the end of a 30,000 mile situation, when the oil gets really low, the rate of consumption is going to go up in a big way.
moron, sorry, person have the vehicle serviced at any point in those 30K miles? Were records retained?
I think I know the answer to both, but thought it best to ask anyway.

Besides new tires and state inspections the car has not been serviced. I think the highway trip certainly did not help and the oil consumption did speed up during the last 10K or so miles. Also, I just recently learned that due to GMs great wisdom, Cadillac uses an oil weight that represents almost nothing at all, ie 0w30. This is what GM puts in the car and this is also what Pennzoil put in the car about 2yrs ago. So, all this suggests that it burned up the paper thin oil, then it was toast. However, in the center of the dash there is an lcd information screen. I am very confident that the owners would have seen and taken action had their of been a LOW OIL indicator, or OIL life info displayed. I just think two bad things happened here, now we will just wait to see if GM is nice to people who have owned 4 Cadillacs or do they feel like being jerks! Any additional responses are appreciated.

As you may or may not be aware, BMW has recently begun using an oil level sensor, to the extent that they've eliminated the dipstick.
Many BMW fans are beyond upset -- they check their oil weekly/monthly. Many of the enthusiasts among them change their own oil.
So. . .we have a car with the feature you're looking for driven by people who generally check their oil regularly vs. a car without it that comes with a perfectly good dipstick.
Everything is not idiotproof. . .yet.

whatever my initial impressions were on your story, as soon as I read that your "friend" had not changed his oil in TWO YEARS, made me lose any and all sympathy for him. If this is true, then he should pay all the costs. Complete disregard and ignorance of the manufacturers recommendations for maintenance are not an excuse. If accurate, this is on him.

I understand where you are coming from. However, it is my opinion that the car should have displayed some type of low oil life or low oil indication prior to causing damage.
thanks for the reply though

My 2003 CTS, built in Feb of 2002, has an oil life indicator(OLI) that sends a message to the DIC (Driver Information Center) when the oil life or oil level is low. It also uses 10W30 oil, not 0W30 (which I don't believe exists).
Since your "friends" CTS is a 2004, it has the same sensor, which is extremely reliable. Apparently, your friend did not pay attention when the message came up.
While GM should be held responsible if the engine were defective, owners are responsible for routine maintenance and should accept the consequences for their negligence.

Have you located a website or dealer who specializes in selling cars with blown or failed engines? Many hobbyists are looking for a "project car" and I would like to start converting these to series hybrid electric cars and see how successful an Electric Used Car Lot (mark-at-serieshybrid.com) might be. For now I can only consider manual transmission vehicles, so probably the CTS doesn't fit my need. But in general, especially in the Internet age, there must be enough of these cases to make a business out of selling cars with major engine failure.
Thanks, Mark (markserieshybrid.com).

Mobil makes a synthetic (Mobil 1) which comes as a 0W30. I use the 5W30 in my SLS.
