How long does a GMC Yukon last?

Full-size SUVs are not the cheapest vehicles to replace, making many consumers look for models with great longevity when shopping for these models.

Replacing a vehicle of this class every four to five years simply isn't in the budget of many owners, some of whom might want an SUV to last a decade or longer. Thankfully, GMC Yukon owners will find that these vehicles are built to last.

You can expect this model to last between 250,000 and 300,000 miles. If you drive an average of 15,000 miles per year, you will get a lifespan of between roughly 16 years and 20 years.

However, getting your Yukon to these higher mileage milestones will require some work on your end. Follow the factory maintenance schedule outlined in your owner's manual.

Seemingly innocuous things like oil changes and mechanical inspections go a long way in keeping your Yukon on the road for many years.

Is the GMC Yukon reliable?

Longevity is an excellent attribute of the Yukon. Knowing that this vehicle will last on the road is essential to consumers who don't want to replace their primary vehicle every few years.

But many folks will still want a vehicle that will not only list but will also be dependable. Time spent in a repair shop or at the dealership can be costly, even if it prolongs your car's useful life.

J.D. Power and Associates has rated the Yukon 73 for overall reliability over the last two model years. This is considered average. Previous years of this SUV have scored substantially higher, however.

The 2020 and 2019 model years were rated 84 and 82, respectively. This is considered "great" by the same rating company.
