“After purchasing a used 2006 STS awd from Cadillac nj in december 2009, wife noticed while making right hand turns on smooth pavement, car seems to stall temporarily not allowing me to accelerate for a few seconds and message traction active is displayed. January 18, 2010,I brought the car back to dealership to complain. They said prob bad gas in lines. Put new gas in and gas treatment for water in tank. Did that, didn't help. February 1, 2010 I returned to dealership to complain it was still doing it on occasion. I asked if there were any complaints on this vehicle. Got a no response. …”
NHTSA complaint #10459155, filed 2012-05, 53,393 miles“Front passenger door does not always open from the outside while stationary, and/or in park, or whether the engine is running or off. If this car is ever in an accident, emergency workers would have to take extra steps, and valuable time, to try to successfully extract any victim from the passenger side. I see it has been reported before!”
NHTSA complaint #10966558, filed 2017-03, 112,445 miles“A high pitch fire alarm noise intermittent going off inside vehicle sometimes deafening, causing the driver to loose all attention and covering ears from sound. The sound seems to be radiating from the 15.1 bose sound system. This problem may present itself at different times weather car is stationary or moving at freeway speeds. This problem has been found in other models ie: cts, STS, srx, and other Cadillac models with this sound system. It seems to be present in model years 2002-2010.”
