GM COURTESY TRANSPORTATION PROGRAM
Program Coverage and Eligibility
“Courtesy Transportation” is defined as any form of transportation permitted within the guidelines of the GM
Courtesy Transportation Program. This includes shuttle, reimbursement of fuel or for use of public transportation
(ride-hailing/carshare apps), and loaner vehicles (including loaners obtained through third party rental agencies).

/EV specific (8 year/
100,000) and Federal Emissions coverage of the New Vehicle Limited Warranty (excluding Low Cab Forward MD

• May be used in conjunction with repairs covered by a GM Certified Pre-Owned Warranty and used vehicles
purchased under the CarBravo program

• Use of a loaner vehicle beyond completion of the warranty repair is the customer’s responsibility.
• During services provided to vehicles in daily and long-term loaner service, demonstrator service, and dealerowned vehicles
• Dealer-owned vehicles not enrolled in the CTP program are not eligible for loaner reimbursement rates.
• Loaner (including third party rental) vehicle insurance, fuel, taxes, levies, or any sort of vehicle licensing fee(s)
Other Related Policies
• To qualify for loaner reimbursement, loaner units must be no more than two model years old.
Note: CTP loaners are restricted to vehicles that are no more than two model years old as of the end of June every
year. For example, on June 30, 2024, only 2023 and 2024 model year CTP loaners qualify for GM Courtesy Transportation reimbursement. See CTP guidelines for additional details.
• Loaners must be directly aligned to brand (and segment within the brand) which is being serviced (e.g.
Chevrolet
to Chevrolet
). Every attempt should be made to provide the same make/model of vehicle that the
customer owns or leases. If this is not possible, upgrades to higher class GM brands should be utilized for
customer satisfaction. When providing a loaner obtained through a third Party rental agency, non-GM vehicles
should only be provided as a last resort.
• For Chevrolet
Medium Duty Silverado 4500/5500/6500 vehicles, it may not be possible to provide customers a
like vehicle. Light duty loaner vehicles should be considered for alternate transportation.

also being applied to the job card.
• A maximum of five calendar days loaner is allowed when express parts shipping (CSO-3) charges are also
being applied to the job card. Please note, dealers are expected to utilize express shipping as needed when a
customer is in a loaner vehicle to minimize both vehicle downtime for the customer and Courtesy Transportation
expenses for GM.
• As of job cards dated Oct. 1, 2024, loaners of 7 or more calendar days must be routed for “GM Authorization” in
Global Warranty Management
• Vehicle loaner periods prolonged by the dealer personnel, processes, shop scheduling and/or practices are
considered the responsibility of the dealership
Field Action Courtesy Transportation Policy
For Vehicles under the New Vehicle Limited Warranty, Courtesy Transportation is available to be reimbursed by GM
if:
1. The vehicle is within the Bumper-to-Bumper coverage, or
2. The involved component is currently covered under the terms of the Powertrain coverage
For vehicles beyond the New Vehicle Limited Warranty Bumper-to-Bumper or Powertrain Coverage, Courtesy Transportation is available to be reimbursed by GM if:
1. The Field Action Bulletin specifically includes provisions for Courtesy Transportation beyond the Warranty
Coverage period (in this situation, the procedure in the applicable bulletin should be followed), or
2. GM pre-approval is granted via the Dealer Aftersales Empowerment Portal. Consideration will be provided on a
case-by-case basis under qualifying extenuating circumstances. Submit requests by selecting "Non-Covered

form of Courtesy Transportation expense (shuttle, one or more days loaner, etc.)
Courtesy Transportation Options

dealer does not operate a shuttle service, then the customer may utilize public transportation (taxi, bus, train,
Ride-hailing and Carsharing such as Lyft/Uber etc.) and submit original receipt(s) for reimbursement consideration up to $7.50 each way. Shuttle of the customer’s vehicle to/from the dealership is a covered service

GM bulletins are intended for use by professional technicians, NOT a "do-it-yourselfer". They are written to inform these
technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper
service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions, and know-how to do a job
properly and safely. If a condition is described, DO NOT assume that the bulletin applies to your vehicle, or that your
vehicle will have that condition. See your GM dealer for information on whether your vehicle may benefit from the
