2000 Cadillac DeVille Problems

TCC Inop Due to Internal Transmission Fault

The torque converter clutch (TTC) may stop working due to an internal transmission failure. The Check Engine Light will illuminate if this occurs. Our technicians tell us the transmission will require dis-assembly to correct this concern.

Misfire Due to Failed Ignition Coil

An ignition coil may fail causing one of the cylinders to misfire. Each of the two banks of cylinders has its own coil assembly. If one ignition coil fails the coil assembly for the corresponding cylinder bank must be replaced.

Heating and AC Temperature and Air Delivery Mode Door Actuators May Fail

One or more heater & AC (HVAC) air delivery and/or temperature mode door actuator may fail. This can result in incorrect air delivery or temperature. If this occurs, fault code(s) stored in the HVAC control module should be available to assist with diagnoses.

2000 Cadillac DeVille 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.

Cadillac Recalls 2000-2002 DeVilles Due to Seat Belt Retractor Lock Up Failure

Cadillac has recalled 2000-2002 DeVille vehicles because the seat belt retractors may not lock as required when in an accident. This increases the risk of injury to vehicle occupants. Dealers will install a retainer kit to the safety belt pretensioners.

Cadillac Recalls 2000-2001 DeVilles Due to Effort Level Required to Release Seat Belts

Cadillac has recalled 2000-2001 DeVille vehicles because the seat belt buckles may require too much effort to release. This may delay exiting the vehicle in the event of a crash. Dealers will inspect the belts, modify latch plates, and replace the affected retractor if necessary. Dealers will also add "snap on" latch clips to ensure proper insertion of the buckles.
