Many consumers view the GMC Sierra 1500 as the standard in the luxury pickup truck market, but there’s more to this pickup than you might expect. All vehicles have issues, and the Sierra steps into higher levels of driving, which could make its problems more costly than most other trucks. With that in mind, let’s examine the three most common GMC Sierra 1500 problems.

Most common GMC Sierra 1500 problems, according to RepairPal

Hundreds of real owners have reported similar problems with this GMC truck. RepairPal tells us the top three issues you might experience with the Sierra are:

  • 4WD transfer case position sensor/selector switch may fail
  • Heating and AC temperature and air delivery mode door actuator may fail
  • Fuel level sensor failure

RepairPal also ranks this GMC pickup high on the list of full-size trucks. Among them, the Sierra 1500 ranks third with a reliability rating of 3.5 out of 5.0. This rating is based on three factors, cost, frequency, and severity of maintenance and repairs.

The average annual cost for repairs and maintenance is lower than average at $727 compared to $936. The frequency of unscheduled repairs for this GMC truck is 0.2 times per year compared to the average of 0.3 times for this truck class. Finally, the severity of these unscheduled repairs is 15% for the Sierra 1500 compared to 18% for most full-size trucks.

Although the GMC Sierra 1500 has trims in the luxury truck category, this pickup truck is more affordable to repair than the average full-size truck.

Another opinion regarding the GMC Sierra’s reliability comes from US News & World Report. These experts rate all vehicles and offer a complete list of the top ten pickup trucks with their reliability ratings. The trucks for the 2022 model year, from best to worst, are:

  • Toyota Tundra
  • Ram 1500
  • Nissan Titan
  • Jeep Gladiator
  • Ford Ranger
  • GMC Sierra 1500
  • Chevrolet Silverado 1500
  • Chevrolet Colorado
  • Toyota Tacoma
  • GMC Canyon
  •  Honda Ridgeline
  • Ford F-150

As you can see, the full-size GMC pickup falls in the middle of the pack for US News, which is much different from what RepairPal tells us. Most likely, the differences in reliability ratings have to do with each organization using differing criteria.

What years of the GMC Sierra should you avoid?

Some of the most problematic model years for this GMC truck are 2014, 2015, and 2017. The 2014 version of the GMC Sierra 1500 has the most reported complaints, including issues with excessive oil consumption, which can be a serious problem. The lights could also fail on this truck, which is another major problem, as reported by Car Complaints.

How long should this GMC truck last?

With proper maintenance, the GMC Sierra 1500 should last at least 200,000 miles. Some trucks will travel much farther than that and still require only a few repairs. This is a truck you could easily drive for more than fifteen years and still enjoy many miles of worry-free driving.

Is the GMC Sierra a good truck?

This full-size GMC truck can be a great option when you want a truck that does many things well. It brings an upscale feeling to the market, giving you a truck that can be welcoming for your family and friends as much as it is for your work crew. There are several great trims, powertrains, equipment levels, and options packages offered for the GMC Sierra 1500.

If you’re searching for the most lavish truck offered, the GMC Sierra 1500 Denali Ultimate has no equal. That said, if you’re searching for the pickup with the highest towing and payload numbers, the Ford F-150 is the truck you’ll want to drive. The F-150 can carry up to 3,325 pounds of payload and has a maximum towing capacity of 14,000 pounds. These numbers beat the GMC Sierra 1500, which offers a maximum of 2,270 pounds of payload and 13,300 pounds of towing capacity.
