Known Issues and Common Problems for the 2015 Chevrolet Tahoe (GMT K2UC Chassis)

The 2015 Tahoe is part of the K2XX generation, which generally boasts good reliability. However, some common issues have been observed:

Active Fuel Management (AFM) / Dynamic Fuel Management (DFM) System Issues: This system, designed to improve fuel economy by deactivating cylinders, can lead to excessive oil consumption, fouled spark plugs, and lifter failure. Symptoms include ticking noises, misfires, and reduced performance. Regular oil changes with high-quality synthetic oil are crucial. Some owners opt for AFM disablers or aftermarket solutions.
HVAC Blower Motor Resistor Failure: This is a very common and relatively inexpensive fix. Symptoms include the blower motor only working on certain speeds or not at all.
Power Steering Assist Malfunctions: Owners have reported a loss of power steering assist, sometimes intermittently. This can be due to a faulty power steering control module or other components in the electric power steering system. Check for service bulletins related to this.
Infotainment System Glitches (MyLink): Issues with the MyLink system, such as freezing, unresponsiveness, or connectivity problems, have been reported. Often, software updates from the dealership can resolve these.
Rear Hatch Liftgate Struts: Over time, the gas struts that assist in lifting the rear hatch can weaken, making the liftgate harder to open or unable to stay open on its own.
Brake System Wear: While not a "defect," the heavy nature of the Tahoe can lead to quicker wear on brake pads and rotors, especially with frequent towing or aggressive driving. Regular inspection is key.
