2019 Gmc Sierra Limited Safety Report

The 2019 GMC Sierra Limited presents a concerning safety profile, primarily due to a high volume of mechanical complaints, despite having no official NHTSA safety ratings or recalls. With 407 total complaints, including 10 crashes, 3 fires, and 9 injuries, the vehicle exhibits significant issues that impact operational safety. A dominant pattern revolves around engine and power train failures, accounting for 88 and 57 complaints respectively. These often manifest as sudden engine stalls, loss of power, violent shaking, and transmission issues like jerking or complete failure, some occurring at highway speeds. Several complaints specifically mention lifter failures in both 5.3L and 6.2L engines, with some owners noting that the 6.2L engine was subject to a recall in later models but not for the 2019 Sierra, despite exhibiting similar problems. Beyond the powertrain, service brakes (40 complaints) and steering (11 complaints) also show notable issues, including instances of power steering failure while driving, making turns nearly impossible. The lack of NHTSA crash test ratings (Overall, Frontal, Side, Rollover are all N/A) means there's no independent assessment of its crashworthiness, leaving consumers to rely solely on the complaint data for safety insights. The absence of recalls for a vehicle with such a high number of critical component failures, especially engine and transmission issues that can lead to sudden loss of propulsion, is a significant red flag. The overall safety picture is one of mechanical unreliability that directly translates into safety risks. The reported incidents of vehicles suddenly shutting off, losing power steering, or experiencing drivetrain lock-ups at various speeds highlight a potential for serious accidents. While the number of reported crashes (10) and injuries (9) is relatively low compared to the total complaints, the nature of the failures suggests a higher inherent risk than the numbers might immediately convey, particularly given the vehicle's heavy-duty nature and common usage scenarios.

Our recommendation: Given the high volume of severe engine and transmission complaints, and the absence of safety ratings or recalls, exercise extreme caution; a pre-purchase inspection by a trusted mechanic, specifically focusing on the powertrain, is essential.
