Heat and Battery Life for Your 2015-2020 GMC Yukon

Why Texas heat, not Texas cold, is what kills batteries. Applied to a 2015-2020 Yukon, here is what that looks like.

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.

Ignition and Engine Management

Watch for fuel economy that drifts down a mile or two per gallon over a few months. Iridium plugs on most modern GM engines are a 90,000 to 100,000 mile item. Coils are replaced on failure, not on a schedule.

Filters and Fluids

Watch for a diesel that derates or throws a fuel pressure code on a neglected filter. Follow the oil life monitor rather than a fixed mileage. Engine air filter every 30,000 to 45,000 miles. Transmission service intervals vary widely by transmission and by whether you tow.

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.

The Short Version

Park assist sensors: Painted park assist sensors are ordered in primer and painted to your code. Confirm your paint code before ordering.
Spark plugs: The same nameplate can have three different engines in one model year. VIN is the only reliable way to get the right plug.
Oil filters: Engine size and emissions equipment change the filter, and diesel filter kits in particular are not interchangeable across model years.
Batteries: Vehicles with stop-start often use two batteries. Confirm which one you are replacing before ordering.

Ordering is easiest if you have the VIN in front of you. Head to our GMC OEM parts catalog to shop by vehicle, or search for Yukon parts to go straight to a part.
