Hunting and Off-Road Season Prep: GMC Sierra 2500HD Edition

Skid plates, lighting, liners and recovery points. Applied to a 2015-2019 Sierra 2500HD, here is what that looks like.

Heating and Air Conditioning

Watch for vents that will not switch from defrost to floor. Cabin air filter every 12,000 to 15,000 miles, or annually. In North Texas with construction dust and cedar season, annually is the honest number.

Electrical and Charging

Watch for the auto stop-start feature quietly deactivating itself. Batteries in Texas heat routinely give up between three and five years. Test annually after year three, before the first cold snap.

Body and Exterior

Watch for a door handle that pulls with no resistance. Not a scheduled item. These are damage and failure replacements.

Sensors, Cameras and Driver Assistance

Watch for a park assist system that disables itself in cold weather and comes back warm. TPMS sensor batteries typically last seven to ten years and are commonly replaced as a set during a tire change.

The Short Version

Cabin air filters: Rear climate content, heated and cooled seats, and tri-zone systems all change the parts list.
Batteries: Vehicles with stop-start often use two batteries. Confirm which one you are replacing before ordering.
Mirrors: Trim level changes almost every exterior part. Take a photo of the connector on the part you are replacing before you order.
Park assist sensors: Painted park assist sensors are ordered in primer and painted to your code. Confirm your paint code before ordering.
