Insuring the Vehicle
Protect your investment in the GM vehicle with comprehensive and collision insurance coverage.
There are significant differences in the quality of coverage afforded by various insurance policy terms.
Many insurance policies provide reduced protection to the GM vehicle by limiting compensation for damage repairs through the use of aftermarket collision parts.
Some insurance companies will not specify aftermarket collision parts.
When purchasing insurance, we recommend that you ensure that the vehicle will be repaired with GM original equipment collision parts.
If such insurance coverage is not available from your current insurance carrier, consider switching to another insurance carrier.
If the vehicle is leased, the leasing company may require you to have insurance that ensures repairs with Genuine GM Original Equipment Manufacturer (OEM) parts or Genuine Manufacturer replacement parts. Read the lease carefully, as you may be charged at the end of the lease for poor quality repairs.
