Powertrain Coverage Explained
Powertrain protection focuses on the components that move the vehicle: engine, transmission, transfer case, drive shafts, and differentials. When a covered internal part fails due to a defect, the plan typically pays parts and labor. It’s budget-friendly coverage that targets “big-ticket” repairs.
Bumper-to-Bumper (Exclusionary) Coverage Explained
Exclusionary plans list what’s not covered, so most other components are included—electronics, infotainment, sensors, climate control, and more. Wear items and maintenance are normally excluded. Expect broader protection at a higher price than powertrain.
