Service engine soon light comes on frequently.....I had vehicle checked a several auto shops and received the diagnosis that my torque converter was possibly slipping. I was quoted between $900 to $ 2100 to repair. I stated for this price I could really just buy a remanufactered transmission. This is ridiculous, there has to be a recall message out there to help fellow owners. I have seen this happening to many other owners who in turn refuse to get this service as it can be very costly.

2003 Cadillac Deville with approx. 65,900 miles on 07/11/07. The "service engine soon" warning light appeared on vehicle control panel & took vehicle to dealership same date 07/11/07. Dealer performed oil change & informed that entire transmission is about to fail & quoted $4,027 for repairs. Dealer refused to honor warranty past 50,000 miles & informed entire cost was the responsibility of the customer. GM was contacted & refused to provide any financial or repair assistance for defect and repeatedly delayed any decision until approximately 08/02/07 (after repeated attempts by customer to contact/resolve problem), other than a $1,000 customer loyalty certificate to buy a new car on approx 8/02/07. GM representative called & recorded phone conversation with customer without customer advance knowledge or consent on 8/01/07 & 8/02/07. Customer had gone to dealership (2nd time) & dealer service mgr. Refused to assist in any way (in person) & stated he will not help & stated his displeasure that GM was contacted. Cadillac was therefore taken to aamco at Cadillac owner's expense for complete transmission replacement. Another issue, "check coolant level light" had been brought to dealership attention (while previously under warranty) & told us to disregard/not worry about it approximately last three times car was in to dealership for oil changes (over approximately six months). Customer was told this is not any safety issue & to disregard "check coolant level light". issue remains unresolved due to assurance of safety from dealership.

Multiple failures with 2003 Cadillac. The check engine light illuminated, cruise control ceased and the transmission had to be repaired.. the consumer was traveling in a heavy rain storm when the head lights and dash board lights went out. The head lights eventually came back on until another heavy rain and they went out again. Consumer was told the water pump was leaking and that was the reason the check coolant level reading was being displayed.
