A GM Severe Maintenance Schedule is a structured plan for servicing vehicles that are subjected to harsh driving conditions, such as extreme temperature changes, frequent towing, or off-roading.
It entails more frequent oil changes, tire rotations, and inspections than the standard maintenance schedule. By following this plan, drivers can enhance the longevity of their vehicles and prevent costly repairs. A key historical development in the automotive industry was the introduction of electronic engine controls in the 1980s, which allowed for more precise monitoring of engine performance and the creation of customized maintenance schedules based on driving conditions.
