Base Warranty coverage limited warranty covers the systems and components of the vehicle, from the front bumper to the rear bumper, for repairs — including parts and labour — to correct any defect in materials or workmanship for the duration of the warranty. There are exceptions for items that wear out such as wiper blades, key fob batteries, brake pads and more; see your Warranty Manual for details.

The Base Warranty coverage limited warranty also includes:

  • Warranty coverage on tires against defects in material or workmanship (note: wear-out is not considered a defect)
  • Towing to the nearest authorized dealership for warranty repairs

A powertrain warranty is a limited warranty for the systems and components of the powertrain such as the engine, transmission and drive systems. The warranty covers specified components for repairs, including parts and labour, due to defects in materials and/or workmanship for the duration of the warranty. Like the Base Warranty coverage warranty, there are exceptions; see your Warranty Manual for details.

Neither warranty covers routine maintenance.


Roadside Assistance comes standard with a new GM vehicle purchase for a set number of months and mileage. It’s also included with select OnStar® subscriptions.

With Roadside Assistance, a specially trained OnStar Advisor is available 24 hours a day, 365 days a year to help you out when the unexpected happens on the road. Emergency services include towing, flat-tire service, battery jump-start and more.  

Refer to your vehicle Owner’s Manual or go here for more details.


My warranty is expired. Can I purchase additional warranty coverage?

Several extended warranty plans are available that can help fill the void of an expired warranty. Contact your dealer for details.

Is it OK to apply a rust-proofing application to my vehicle?

Chevrolet, Buick, GMC and Cadillac cars and light-duty trucks are designed and built to resist corrosion.

Application of additional rust-inhibiting materials is neither necessary nor required under the sheet metal coverage. Chevrolet, Buick, GMC and Cadillac make no recommendations concerning the usefulness or value of such products. Application of after-manufacture rustproofing products may create an environment that reduces the corrosion resistance built into your vehicle. Repairs to correct damage caused by such applications are not covered under your New Vehicle Limited Warranty. See your Chevrolet, Buick, GMC or Cadillac dealer for terms of this limited warranty.

Can I take my Chevrolet, Buick, GMC or Cadillac vehicle to any General Motors dealership for warranty repairs or included maintenance?

Chevrolet, Buick and GMC owners may take their vehicle to any General Motors dealership (excluding Cadillac) of their choice. It’s advisable, however, to take your vehicle to a dealership that matches its brand, as they will be the most familiar with your vehicle’s specific needs.

For included maintenance, Chevrolet, Buick and GMC customers can go to any dealership; Cadillac customers must return to a Cadillac dealership.
