Cadillac issued a tsb in April 2012 (tsb #pit-3749D), which is also noted as NHTSA id #10037570 regarding rust and frame corrosion. My 2005 Cadillac Srx is experiencing this issue, and I was just quoted $5700 to repair the manufacturing defect. Why isn't the NHTSA requiring a recall if the structural frame of the car is eroding away? I can send you all my correspondence with Cadillac corporate over the past two weeks.

The contact owns a 2005 Cadillac Srx. After purchasing the vehicle from an independent dealer, the contact took the vehicle to a certified Ford dealer. The technician diagnosed that the engine light was illuminated and the drive shaft couplers, power steering, front wheel bearing, and motor mounts were all defective and needed to be replaced. The vehicle was returned to the independent dealer who refused to repair the vehicle. The manufacturer was not notified of the failures. The failure mileage was approximately 109,916.

Driver door latch stays in the open position, preventing the door from latching closed. After sitting for a while, over night or a few days, door will latch closed again. This is a interment problem. Concerned will occur while driving as it appears to be effected by the electric lock system. Checked on web several others have had this problem also.

Right and left turn singles have gone out 6 to 7 times since I have owned the car. When they are replaced they only last a few weeks. My dealers sates that the plugs need replaced. I have heard that this affects 2004 through 20009. With large number I think it should be recalled. 30% of all accidents are caused by not using or faulty turn singles. The dealer charges $200 to replace the bulbs per side.
