2019 GMC Yukon Reliability Report

Owners of the 2019 GMC Yukon frequently report issues with power steering failure, often accompanied by a "Service Power Steering" warning message. Symptoms commonly include sudden loss of power steering, especially at highway speeds, and instances where the steering wheel feels disconnected or surges during travel. These issues typically occur at varying mileages, with some reports indicating problems as early as 6,408 miles. One complaint describes a crash involving two injuries, attributed to a sharp, uncontrollable pull of the steering wheel. Buyers should be aware of potential safety implications due to these steering issues, as they can lead to loss of vehicle control.

Owners of the 2019 GMC Yukon frequently report issues with the service brakes, particularly involving unexpected automatic emergency braking activation and persistent "Service Trailer Brake System" warnings. Several complaints describe the brakes failing to operate, with one instance involving a firm brake pedal and failure to stop, leading to a vehicle coasting through an intersection. Another complaint notes brake lights ceasing to function entirely. Mileage at the time of failure varies, with one report at approximately 131,600 miles and another at around 12,000 miles. Safety implications are significant, with reports of near-collisions and loss of braking power, posing potential risks to drivers and passengers.

Owners of the 2019 GMC Yukon frequently report engine-related issues, including abnormal ticking, knocking, and banging sounds. Complaints often describe engine misfires, lifter failures, and in some cases, catastrophic engine failure requiring replacement. These problems typically emerge at varied mileages, ranging from as low as 7,000 miles to over 127,000 miles. Some reports also mention coolant intrusion and fuel pump failures, with symptoms like rough idling and the check engine light illuminating. While no crashes or fires are reported, the recurring nature of these issues may affect the vehicle's reliability and performance, which used car buyers should consider.

Owners of the 2019 GMC Yukon report several issues, with air conditioning failures being a common problem. Multiple complaints describe the air conditioning system blowing hot air or failing due to refrigerant leaks, even after repairs, with one owner noting this issue at six years of vehicle age. Another significant concern involves a vehicle fire, attributed to an electrical system failure, which occurred overnight and resulted in the vehicle being completely burned. Additionally, one owner reports transmission issues with slipping and unexpected slowdowns at approximately 132,000 miles. These issues highlight potential safety risks, particularly the reported fire, and suggest that prospective buyers should be cautious about these specific problems.

Owners of the 2019 GMC Yukon report issues with the suspension system, primarily involving seized rear shocks and leaking front strut assemblies. Symptoms frequently described include difficulty controlling the vehicle on uneven surfaces and excessive bouncing, leading to compromised handling and steering. Complaints suggest that these issues may be common, as dealers indicate a high stock of replacement struts and note a design change in 2019. No specific mileage is mentioned, but the problems are identified during routine inspections. Safety implications include potential loss of vehicle control, although no crashes are reported. This information is pertinent for used car buyers considering this model year.

Owners of the 2019 GMC Yukon report issues with airbag non-deployment during crashes. In one instance, a Yukon was struck by another vehicle at 65 MPH, resulting in severe front-end damage and three injuries, yet no airbags deployed. Another report involves a collision with an elk at 65 MPH, where airbags also failed to deploy. Both incidents suggest a potential pattern of airbag non-deployment in high-impact situations. The reported mileage at the time of the first incident was 170,000 miles, but no mileage was noted for the second. These complaints highlight safety implications, particularly in severe collisions where airbag deployment is expected to mitigate injuries.

Owners of the 2019 GMC Yukon report issues related to vehicle speed control, with two primary patterns emerging. Some describe the engine unexpectedly giving out while driving, accompanied by shaking and a sudden loss of speed, which can lead to being stranded, as one owner experienced on the interstate at night. Another common issue involves unintended surges at high RPMs shortly after starting the vehicle, occurring approximately twice a week, and almost causing accidents due to unexpected acceleration. Safety implications are significant, as these problems can lead to loss of control. These issues are reported on vehicles with the 6.2L motor and 10-speed transmission, with no specific mileage range consistently noted.
