Check engine light continues to illuminate even though I have changed both o2 sensors twice. Dealer keeps telling me I need another o2 sensor. Aldata shows a software upgrade is neede to correct the problem.
I was at a complete stop. I started going up the driveway, I felt the car lurch foreward. I thought I was slamming on the brake, but hit the gas instead. The car crashed into the house moving the concrete block. The airbags did not deploy. I broke my neck at c4 and c5. I have seen 3 reports on this site detailing the same. All these cars were 2007 cadillac sts. With all the problems with gm and airbags, could this be related? *Tr
This cadillac make & model does not have an american engine, a fact that was not disclosed to me upon purchase. The engine light has came on several times in the past and dealership would mess with wires under seat and somehow get the light to go off and tell me it was the airbags that would make the sensor go off. Then when I pay my last note and get to 100,000 they decide to reveal to me that the same engine light defect means real engine problems.

the problem I was told by both that this was not an american engine but a very cheap german engine and that they had a large number of people having the same problem, with some having to sell their car for scrap metal.

Timing chain failures under 30,000 miles are prevalent on many gm 3.6L motors and they have sent out a letter explaining that "under certain driving conditions and with extended oil change intervals, the timing chain can wear prematurely causing the service engine light to come on"... There are hundreds if not thousands of these failures documented on the auto blogs/forums.. And this is a blatant attempt by gm to change the engine performance and cause more frequent oil changes in and effort to get engines to last...

outside of warranty (all most all are failing within warranty. I received a letter on march 14th, 2011 from mr. [[redacted]], general director of customer service, asking me to bring the car in to have the ecm modified to prevent failure of a known design problem... This is totally unacceptable solution to a design flaw... Causing me to take the risk of future failure and thel limit future liability by downgrading my 2007 cadillac sts's performance and making me change the oil sooner that their engineered oil change computerized program recommends... To prevent a failure that is almost guaranteed to happen! Information redacted pursuant to the freedom of information act (foia), 5 u.S.C. 552(B)(6).*Tr
