2005 Cadillac CTS Owner Comments

CTS 6-cyl

  • 63,000 miles


I have a 2005 Cadillac Cts with 67,000 miles. Since about 65,000 miles car has been making a rattling sound under the hood during acceleration. I have given the car a tune up, oil change and the car has other fluids are at level. Once my car has accelerated and the gears have changed (I.e, second gear) the rattling sounds stops..the noise is continuous and only happens at acceleration, not while idling. In addition every now and again when a front seat passenger gets in the car the airbag sensor/light comes on the dashboard. This problem doesn't happen often but it happens every once in a while. Upon doing my research for both these issues I find that I am not the only one having this problem...hopefully something will be done so that GM can address these serious issues without having the consumer/owners having to pay an arm and a leg.

: the contact stated there are several things wrong with the vehicle. The check coolant light and the check engine light illuminated on the dashboard. The dealership determined the radiator was damage and attempted to repair the radiator four times. The first three repairs performed by the dealer in an attempt to repair the radiator were unavailable. The fourth time, the dealership determined the problem was with the water pump and the water pump was replaced. The fuel pump was also found to be defective and was replaced. The check engine light illuminated on the dashboard prior to the fuel pump problems. The drive shaft was defective causing the vehicle to become inoperative. The crs light illuminated in the vehicle. There was an unknown part replaced to repair the crs light. The driver's power window worked intermittently making a grinding noise and the dealer repaired the window. The wiring was in backwards on the passenger seat causing only half of the seat to move. The dealership corrected the wiring to repair the seat.
