GMC Sierra Texas Edition: Review and Maintenance Tips for 91K Miles
GMC Sierra Owner Warns of Transmission Issues
Are you considering buying a GMC Sierra truck? Before you make a decision, take a moment to hear Shannon Elizabeth’s cautionary tale. She owns a 2019 GMC Sierra Texas Edition that may look stunning on the outside, but don’t be fooled—the transmission has given her nothing but trouble.
Shannon’s upscale Sierra truck, complete with all the luxurious upgrades you could dream of, has a dirty secret hidden beneath the surface. Despite its chrome wheels, premium Bose audio, power sliding rear window, LED cargo bed lighting, and dual-zone climate control, the transmission is a weak spot in these models.
It turns out that Shannon’s transmission troubles are not an isolated incident. General Motors is facing a class action lawsuit due to allegedly selling hundreds of thousands of vehicles, including the Sierra, Silverado, and Escalade, with defective transmissions. Shannon’s story sheds light on the frustrating reality that many GMC truck owners are facing.
In Shannon’s own words, “My truck might look really nice and expensive, but I’m here to tell you, it’s the biggest piece of (expletive) I’ve ever owned in my life.” Her transmission failed at 80,000 miles, beyond warranty coverage, and now, with only 10,000 miles on a new transmission, she’s facing the same issue all over again.
Unfortunately for Shannon, the reduced value of her truck leaves her unable to trade it in for something more reliable. She’s stuck with a vehicle that looks good but runs poorly, turning into more of a liability than an asset due to its transmission woes.
The transmission problems in GMC trucks are not just limited to older models; even the 2020 and 2021 Sierra and Silverado trucks have reported similar issues, highlighting ongoing challenges for GM. The lawsuit continues to gain traction, with a scheduled rehearing in March 2025.
Shannon’s advice to potential buyers is simple: steer clear of GM vehicles. Her experience serves as a cautionary tale for anyone considering a Sierra, Silverado, Yukon, Escalade, or another GM model. If you’ve faced transmission issues with your GM truck, your story might be more common than you think.
Stay informed as we await updates on the class action lawsuit and the ongoing transmission issues surrounding these popular GMC trucks.
