2006 Cadillac DTS Problems

Oil Leak From Lower Engine Area

The engine may develop an oil leak from the lower crankcase portion of the engine block. Our technicians tell us that the engine must be removed from the vehicle to properly repair this oil leak.

Engine Overheating Due to Leaking Headgasket

Overheating of the engine may cause the cylinder head to expand, severely straining the head bolts and damaging the threads in the engine block. This commonly results in a blown head gasket. Our technicians tell us the engine block threads must be repaired before the cylinder head is reinstalled.

Coolant Leaks From Water Pump and Radiator

The water pump and/or the plastic side tanks on the radiator may leak causing a loss of coolant. The engine may overheat due to coolant loss. Continued coolant loss after external leaks have been repaired could indicate a blown head gasket.

2006 Cadillac DTS Recalls

Ignition Lock Cylinder Concern

Excess weight on the key ring can cause the ignition switch to move out of the run position without warning, turning off the engine. This defect can also affect the safe operation of the airbag system. Until this recall is performed, customers should remove all items from their key rings, leaving only the ignition key. The key fob (if applicable), should also be removed from the key ring. Dealers will install two 13mm key rings and key insert into the vehicle's ignition keys to correct this concern.

Possible Under Hood Electrical Fire

The heated washer module under the hood could overheat due to excessive current draw. Under certain conditions, this could result in an under hood fire. This previous recall attempt in 2008 to repair this concern did not have the expected success. Dealers will now permanently disable and remove the heated washer module to correct this concern. This recall is expected to begin on June 20, 2010.

Possible Under Hood Electrical Fire

The wiring to the washer system heater may overheat due to a failure in the heater module. This could cause other electrical features to malfunction, smoke to develop, and an electrical fire could result. Dealers will install a wire harness with an inline fuse to protect the washer heater module. This recall is expected to begin on September 12, 2008. The General Motors recall number is 08048.

2006 Cadillac DTS Reviews

the seat motor burned out, only had car 6 months. took auto to repair shop. put the new motor in, but still not working because there is a computer that controls the motor to make the seats move back and forth. Having to take car to the Cadillac dealership because they are the only ones that can repair it
I liked my dts just too many problems that all cost to much. I got mine given to me. I decided I was not putting any more money into it. So I took it to the dunes.. one awesome day. We jumped it twice then it caught on fire. Sorry no video.. don't ever get a Cadillac dts or any Cadillac for that matter..
