Thank these things I feel cadilac should consider fixing due to milage before and after I purchased the cadilac due to the miles before and after purchase. Due to being 100% disabled since 2009, air bag & safety belt system light comes on when I have onstar diagnose the problem they said it has something to do with my seat belt system on passenger side which mind you isnt used often at all and cadilac will not help with the cost and was told by onstar it needs repairs ASAP because it could cause air bags to pop out while driving or not come out during a crash. Im afraid some times driving it. In the 7yrs of owning this I maybe put around 40,000 miles on the car its in good condition. Which lead me to the other problem due to miles. When I purchased the cadilac a few days later the check engine light came on it was the catalytic converter it was almost $800 it has two of them the dealer repaired it. Here the other day I had onstar do a complete system scan and the report showed the converter was in the process of going out again but just hasnt triggered my check engine lite. I was shocked because of the miles I drivewhich is under 6000 miles a yr and I use top grade fuel there isnt any way these converters should be going out they should have lasted for the rest of my life and the cars life I take very good care of it changing the oils on a regular bases and other cares are met but when talk to cadilac they didnt even consider my care and miles driven at all or find out why tne converter is needed twice since I owned the car when most cars never need converter replacement. Im 62 yrs old, these are concerns I have but mostly the treatment by cadilac (gm) the safety part being on passenger side that seat never hardly get used but could cause air bags to open while driving and two convertersin 6-7 years of ownership when most cars never need one and othhers just once. Which tells me theres a problem some where else causing it to not work properly, but it didnt matter.

This vehicle has had thousands of complaints about ecm related problems. Every complaint is the same. The computer causes the temp gauge, fuel gauge to stop working, the tc light & antitheft lights to come on, and the key being stuck in the ignition. It renders the car undriveable because the temp & fuel gauges stop working. I have researched this and there has been the exact same issue with thousands of cars!!! when I contacted Cadillac about this they said I would have to pay hundreds of dollars for a diagnoses fee. I told them that this is obviously a defect with poor design and/or bad parts. I have included just one of many links that owners have had with this model of car. . Read more...

I was at a stop sign when I tried to press down on the gas the car started tug and it would only do that on the first gear one mechanic said that it has to do with the fuel system and I kept testing the car out and I kept pressing on the gas to see if there was a difference but it kept doing the same thing as the first time.

On 07/26/2015 went to start car. It started ok, but then there was no power to dash non on my indicators came on, when I went to put the car in drive the gear shift would not move. So I went to turn the car off, at this point the key would not turn all the way to full off position and is stuck in the ignition, all night. This of course means the alarm would not go on. So key stuck in ignition, no alarm, no dash power. This of course by morning had killed a new battery of only 5 days old.

Driving on the freeway and the car just died on me in the middle of the highway. Had to get it towed to the shop found out it was the timing chain.

Timing making a chatter noise.

I had timing chain done on my car in oct. Of 2011 at jack wolf in belvedire, IL at the time the car was fixed under a extended warranty. I then had the same problem happen again Jan. 2013. I called gm I was told that then would not fix it even though it had only been a year and 6 months since the problem happen before.

I was driving the vehicle and was hit from behind and went into a curb. My airbags did not deploy and the car would not restart. The engine completely shut off. The car continue to have problems with the engine and smoking after it was repaired by a gm dealer. We had to turn the car in and file bankruptcy after it stopped working.

Had used 1 qt oil in 5,000 miles on previus oil change and now has used 2. 5 qts in 4,000 miles.
