Recalls for the 2001 Cadillac Deville: 4
This defect can affect the safe operation of the airbag system. The key fob (if applicable), should also be removed from the key ring. If the key is not in the run position, the air bags may not deploy if the vehicle is involved in a crash, increasing the risk of injury.
Certain passenger vehicles contain driver and front passenger lap and/or shoulder belt retractors that may not remain locked up as designed during a crash in which the belt pretensioners deploy. In such a crash, this could result in an increase in injury for that occupant.
Vehicle description: certain sedans, hearse, and limousine vehicles fail to comply with requirements of FMVSS no. 201, "Occupant protection in interior impact." These vehicles have sunvisor center supports with certain radii less than the 3.2MM required by the standard. Radii less than 3.2MM can increase the possibility of certain types of injuries, like lacerations, if an occupant contacts the support during a crash.
Vehicle description: passenger vehicles, hearse, and limousines. Some of these vehicles fail to comply with the requirements of FMVSS no. 209, "Seat belt assemblies." These vehicles have seat belts that may not meet the 30-POUND push button release effort requirement of the standard. High release efforts could make it more difficult for a crash victim to release the belt and exit the vehicle.
