The 2020 GMC Sierra 1500 Already Has Four Recalls for Dangerous Problems

The 2020 GMC Sierra 1500 is comparable to the 2020 Chevrolet Silverado 1500. Both half-ton pickup trucks receive similar reviews and performance ratings, but the Sierra has a better overall look and feel to it. The new trailer-tow mirrors and camera system help make hauling up to 12,200 pounds a breeze. With several different engine options, this truck has a setup that fits any driver’s needs.

Where the 2020 GMC Sierra 1500 falls short is in its reliability. General Motors currently has four active recalls issued on this vehicle. Consumers are concerned – with good reason – about so many manufacturing problems on a new model truck.

Upgrades and improvements to the 2020 GMC Sierra 1500

GMC has beefed up the 2020 Sierra 1500 with improved powertrain options, and a 10-speed automatic transmission option that is now available in more of their models. The Duramax turbodiesel inline-six engine, which was introduced in late 2019, is more readily available in the 2020 GMC Sierra 1500. The carbon-fiber truck liner is also a welcome addition, along with the deeper bed.

Technology upgrades abound in the 2020 GMC Sierra 1500. The option of adaptive cruise control can be added to most trim levels. An 8-inch infotainment system, compatible with Apple CarPlay and Android Auto, now supports Sirius XM satellite radio. Rear cameras offer “see-through” towing effects that enhance the driver’s ease of operation and comfort level.

The 5.3-liter V8 engine now offers quicker acceleration and enhanced throttle response. The Dynamic Fuel Management system allows for better fuel economy with the Sierra 1500 getting 17 mpg overall, and the diesel option topping off at 23 mpg.

The interior of the 2020 GMC Sierra 1500 is basic, according to Consumer Reports, who called it “unimpressive for a $50,000 truck, with cloth seats, cheap-looking controls, and a clunky old-school column-mounted gear selector.”

Although the cab is spacious, the huge climb up is a hindrance, and running boards, that are not included, are a must. Consumer Reports gives the beefy truck a one-out-of-five predicted reliability score, mainly due to the number of recalls that have already been issued for the 2020 model.

NHTSA safety recalls 

There are four recalls currently active on the 2020 Sierra 1500 pickup truck.

According to NHTSA Recall #20V116000, the bolts used to secure the front and/or rear brake calipers may not have been properly heat treated. These bolts may break under load, reducing brake performance or interfering with proper wheel rotation.

A problem with the electrical system has affected 350,371 vehicles. NHTSA Recall #19V888000 states that there is “an intermittent electrical connection between the B+ battery cable and the alternator.” This problem could cause the vehicle to stall and may lead to electrical arcing, increasing the risk of fire. In the recall notice, GM states, “The battery positive (B+) cable rings may have been manufactured with excessive glue.”

NHTSA Recall #19V837000 states that the 2020 GMC Sierra 1500 may be missing a pressure regulator on the fuel pump. Over-pressurization of the fuel system can cause leaks, and possible cracking of the fuel pump may occur. The risk of fire is increased when an ignition source is present.

The fourth recall, NHTSA #19V814000, affects the entire GMC Sierra truck line with 556,399 vehicles potentially affected. Certain trucks with carpet floor covering are susceptible to a vehicle fire. GM states that “When the front seat belt pretensioners deploy, hot gas may vent through an opening in the pretensioner bracket, possibly igniting the carpet.”
