The National Maintenance Agreement (NMA) is a vital part of the commercial vehicle industry, particularly for companies that operate fleets of vehicles. It is an agreement between manufacturers and dealerships that establishes standardized maintenance and repair procedures for commercial vehicles.

General Motors (GM) is one of the manufacturers that participate in the NMA program. The company offers NMA solutions to its fleet customers to help them manage their vehicles effectively and efficiently, thus reducing downtime and ensuring that their fleets are always in good condition.

Let`s delve deeper into what the GM National Maintenance Agreement is all about and how it can benefit your business.

What is the GM National Maintenance Agreement?

The GM NMA is a partnership between GM and its authorized dealerships to provide maintenance and repair services for commercial vehicles, including medium-duty and heavy-duty trucks. The NMA program is designed to ensure that all GM commercial vehicles are maintained and repaired to the manufacturer`s standards.

The program requires dealerships to have trained technicians who use genuine GM parts and follow established repair procedures. The NMA program also offers businesses predictable maintenance costs, extended service hours, and emergency roadside assistance.

Benefits of the GM NMA

1. Reduced Downtime

Downtime can be costly for any business, especially those that rely on their commercial vehicles to deliver goods and services. With the GM NMA, businesses can have their vehicles serviced and repaired quickly, reducing downtime and increasing productivity.

The NMA program offers extended service hours, meaning that businesses can have their vehicles serviced outside regular business hours. This helps eliminate the need for businesses to temporarily take their vehicles off the road for maintenance or repairs, reducing downtime further.

2. Lower Maintenance Costs

The GM NMA provides predictable maintenance costs, allowing businesses to budget for maintenance expenses effectively. Having an established maintenance schedule also helps detect problems early, minimizing the chances of costly repairs that could have been prevented by regular maintenance.

3. Improved Vehicle Performance

Regular maintenance is key to maintaining the longevity of any vehicle. The GM NMA ensures that vehicles receive scheduled maintenance and inspections, which can improve vehicle performance and fuel efficiency. The NMA program also requires that only genuine GM parts be used during repairs, ensuring that vehicles perform as intended.

4. Emergency Roadside Assistance

The GM NMA program offers businesses 24/7 emergency roadside assistance for their commercial vehicles. This means that if a vehicle breaks down, GM-certified technicians will be dispatched promptly to the location and provide the necessary repairs on-site or tow the vehicle to the nearest dealership for repair.


The GM National Maintenance Agreement is an essential program for any business that operates a fleet of commercial vehicles. The NMA ensures that vehicles are maintained and repaired to manufacturer standards, reducing downtime, and improving performance. With predictable maintenance costs, extended service hours, and emergency roadside assistance, businesses can focus on their core operations while ensuring their fleets are in top condition.
