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.
