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 DeVille Reviews

I put a Cadillac converter on here but the car is acting like it don't want to moveI put a water pumpthermostat radiatorsome more stuff just cant think right now
think its a wonderful car,yes like any other mode of transportation it will require maintenance. I would say if one doesn't want to do repairs,buy new and trade early. These cars represent a time when this country made great products, the ride the comfort ,the extra horsepower when you need it all within your reach. Personally, I own two Devilles, and wouldn't trade them . I actually enjoy...
