The Limited Lifetime Parts Warranty is just another example of your kind of luxury that comes with the Buick experience. The Limited Lifetime Parts Warranty is an advantage of bringing your vehicle to the Buick Certified Service experts for repair and replacement parts. This warranty is available at your Buick dealer.

Our dealers stand behind their GM Original Equipment products, and many auto parts are backed by our Limited Lifetime Parts Warranty. If any of the auto parts listed below are replaced by a Buick, GMC, Chevrolet, or Cadillac dealer in a customer-paid transaction, the part is covered by our Limited Lifetime Parts Warranty. If the eligible auto part ever needs to be replaced, the Limited Lifetime Parts Warranty will cover the cost of the new auto part. Warranty is not transferable. Installation is extra.

Eligible Auto Parts Include (applies to GM Original Equipment Parts only):


The Limited Lifetime Parts Warranty covers only parts that meet all of the following criteria:

  • Must be an eligible GM auto part listed above that was replaced after 1/1/13
  • Must be on customer-paid repair order
  • Must be originally installed by a Buick, GMC, Chevrolet, or Cadillac dealership

If an eligible auto part needs to be replaced, any Buick, GMC, Chevrolet, or Cadillac dealership will repair or replace it free of charge to the original purchaser. Installation is extra.

The following GM passenger cars and light-duty trucks (Series 10-30) are eligible for this Limited Lifetime Parts Warranty:

This auto part warranty remains in effect for as long as the original purchaser owns the eligible vehicle on which the part(s) was originally installed. The original purchaser seeking a repair must return the vehicle to a Buick, GMC, Chevrolet, or Cadillac dealership. The original purchaser must provide a copy of the original auto repair order showing that a Buick, GMC, Chevrolet, or Cadillac dealership had earlier replaced the warranty eligible part.
