Hello,     I purchased a 2006 Sts V8 last January. Since then I have had to replace all four tires immediately, a starter, and the brakes and then replace front brake pads again.  I recently went to auto shop and was told catalytic converter and suspension need to be replaced.      after investigation I realized there was recalls on the 2005 Sts V8 model for the  brakes, suspension and the catalytic converter has an extended warranty of 12 years and 200000 miles.   the fact is that further investigation showed my car was built in 2005 and the actual manufacture date on vehical was 6/20/2005 which was last date of production for the 05 model.  the 2006 manufacture or build date began on 6/23/05.  it seems odd all the recalls for the 05 model are all the year old vehicle are faced with.  I called Cadillac and they said although the build date of vehicle is valid the VIN number is what is followed.  however, further research shows they actually found the same recall on the 05 catalytic converter on a 2007 Cadillac.      everything points to the fact that the  my 2006 model was actually either a late model of a 2005 by the build date of 6/20/05 and or the same parts have been used as the 2005 recall.  lastly the VIN number when I pulled up on a site showed it was actually a cts model.   I have spent a lot of time and have a great deal of data I could share that would back that my 2006 Sts V8 actually is part of the recall cars.    I understand the VIN number is what is looked at but when model year cars are being made and sold as different years than when they are produced and recalls effect the year of actual build this becomes very concerning.  as in the past year I will be spending over 3000$ plus dollars to fix this car.    I.hope you can look into.  as  they wont even investigate or give me the serial numbers for the parts being recalled

STS 6-cyl

  • Automatic transmission
  • 35,000 miles
I lease a 2006 Cadillac Sts with 35,000 miles driven. For the past 6,000 miles, an increasing thumping noise has been emanating from the front wheels. I brought it to the Cadillac dealer I got it from (country Cadillac GMC Buick, huntington, NY) and their brief synopsis indicated that the tires were worn out, because there are flat spots on them causing the thumping. The problem is, Cadillac explicitly warranty?S the tires from defects for full replacement during the bumper to bumper coverage of 5 year/50,000 miles. I contacted Michelin to discuss warranty coverage and they instructed me to bring the car into a service center to analyze for warranty. Their analysis indicates that any wear of this type is mechanical in nature, and it is a root cause within the front end of the car. I contacted Cadillac customer service specifically (and adamantly) requested that a regional representative from Cadillac come to the dealership to review the car with me & the dealers service manager. After fully disclosing all the information about the tread life (which Michelin clearly claims that there is a minimum of 3/32" active life left before the low level indicator bands are breached) and that the "flat spots" are not normal tread wear, and that I require a meeting to review the situation. I received a call back from the customer service representative informing me that this is also not a warranty issue. This is the problem. I know that my car has an inherent problem. This wear irregularity is currently a serious safety issue, and I need new tires before an incident happens. My contention is this; Cadillac is ignoring the underlying problem, blaming it on "worn out" tires, when in fact there is a major problem. I will replace these tires, but the point is Cadillac really should, and also should actively be reviewing the car front end for defects; one which deteriorates critical safety components on my car.
