2017 GMC Sierra
The 2017 GMC Sierra, a full-size pickup truck, offers robust capability but comes with notable reliability concerns for used-car shoppers. Its 6.2L V8 engine paired with an 8-speed automatic transmission provides strong performance, achieving an EPA-estimated 17 MPG combined. However, the vehicle's Achilles' heel lies in its power train and service brakes, which are the subjects of the most frequent and severe complaints. Despite a lack of official recalls, the sheer volume of owner complaints and a high TSB count suggest a complex ownership experience. Buyers should prioritize thorough inspections of these critical systems.
Critical Failure Risk
Complaints frequently cite harsh shifting, shuddering, hesitation, and transmission fluid leaks. These issues can arise at relatively low mileage, impacting drivability and potentially leading to more significant failures if unaddressed.
Early detection can help you avoid a $1,500-$4,000 repair.
