I-CAR Collision Repair Of The 2021 General Motors (GM) Full-Frame Sport Utility Vehicles (SUV) Course
The GM full-frame SUVs have undergone a redesign for 2021. This has brought about various structural changes, as well as construction material changes.
The Collision Repair Of The 2021 General Motors (GM) Full-Frame Sport Utility Vehicles (SUV) course allows technicians to learn about the construction of these full-frame vehicles, along with many other topics, such as:
- Design changes
- Repair highlights
- Construction material
- Structural procedures
- Advanced driver assistance systems (ADAS) overview
The SUVs that have been redesigned are the:
- Yukon
- Yukon XL
- Tahoe
- Suburban
- Escalade
One of the most noticeable changes is construction materials. GM uses a combination of the following materials for the vehicle body:
- High-strength low alloy (HSLA) steel
- Ultra-high-strength steel (UHSS)
- Dual-phase (DP) steel
- Mild steel
- Aluminum
The course details the use of aluminum throughout the body. Aluminum is used for closure panels, i.e. door panels, hoods, liftgates. Steel is used for the rest of the body structure, including:
- Fenders
- Outer quarter panels
- Roof panel
- A-pillars
- B-pillars
The frame is comprised of mild steel, HSLA steel, and a few aluminum components. Repair options for the frame are explained in the course.
You will also learn of the standard ADAS packages on GM SUVs, along with optional ADAS. The course will walk you through how to navigate the GM ADAS configuration reference document.
