Just bought the vehicle used and I hear a noise coming from the rear back of the car. The key fob wasn't working correctly and drained the battery and I had to buy a new battery. I really don't know what wrong with the vehicle but its driveable for now besides the slight banging noise. It need to be checked for recalls.

The rear pinion seal on my car has failed a long time ago. It is oddly strange how the 2005-2007 Cadillac builds have this problem, yet, somehow my VIN isn't included in the safety recall. This appears to be a wider problem than the bulletin covers. This really needs to be addressed as someone is going to be driving one day and their car is going to stop abruptly and cause a major accident. This is a major problem!

Driving on the highway when there was a sudden loud bang, my car swerved, my rpms revved up, white smoke and I smelled burning. I pulled over and had it taken to the local certified Cadillac dealership, my rear differential needs to be replaced related to a rear pinion seal leak. There's a recall for that exact problem for my year and model but my VIN isn't covered. How can I get my VIN on the recall list?

My 2005 Cadillac Sts brakes locked up and caused my car to crash. After research I am showing that there was a recall regarding the brake system. In addition, when changing gears you can hear the gears changing from the outside of the car. I researched this as well and apparently there is a defect and recall on the axle. I am not happy about this vehicle that I just purchased for alittle over 7 months. There is also an electrical problem. As I am driving, the hood ajar light comes on and there is no sign of my hood being ajar. In addition, the transmission seems as thought it is going out as well. Before I consult with an attorney I wanted to first give GMC an opportunity to resolve this issues. My vehicle has less than 100,000 miles. Also, please note that due to the electrical problem, my reverse lights has never worked. The unknown other would be the axle and transmission.

Rear differential very wet and leaking in garage. Called GM was ask several questions and told to carry it to crest Cadillac, hoover, al and let them check problem. Was told not to let them fix it and GM would call me to see what I was told. I did carry it to crest Cadillac and was told it is the rear pinion seal and is very common. GM called me back and ask what they said and ask several question again then told me it is not covered under any recall and would not help with repair.

The above vehicle was recently in a shop for brake pad replacement when my mechanic discovered that there was a leak of lubricant in the rear end of the automobile. Upon further inspection he discovered that the rear axle pinion seal was leaking. The automobile has just 60,000 miles. After checking the NHTSA he found that a recall, GM recall number 07204 had been issued for this very problem. However, when I presented the vehicle for repair this morning at marion Chevrolet Cadillac they refused to cover the problem under the recall stating the VIN does not meet the recall range. I find it untenable that GM could recall nearly 300,000 vehicles for this very issue but refuse to cover an identical problem in a vehicle that does not meet the VIN range set by GM.
