5/5 Overall
NHTSA 5-Star Safety Rating
Complaints about the 2020 GMC Acadia cluster most heavily around the powertrain, engine, and electrical system. On the engine and powertrain side, owners frequently report a thermostat stuck open, which causes the engine to run cold and triggers a cascade of related symptoms, fans running at high speed, air conditioning that won't engage properly, reduced electric power steering assist, traction control dropping out, and the check engine light coming on. Several owners describe these issues occurring together rather than in isolation. On the electrical side, infotainment screen failures are a recurring complaint, with owners reporting the display going dark or showing only lines, which also disables the backup camera. A separate pattern involves the backup camera cutting out in reverse and causing the radio to cycle on and off, suggesting a possible wiring issue in that circuit.

By System
The 2020 GMC Acadia has 7 recalls, the most serious involving a fuel pump defect that can cut fuel supply to the engine and cause a sudden stall, a transmission component with missing bolts that can leak oil and result in loss of propulsion, and Continental tires that can develop a sidewall break or shed tread without warning.
On the safety equipment side, the curtain airbag inflator's diffuser component may not be properly secured and can separate during deployment, reducing the protection the airbag provides in a crash. There is also a separate fuel system concern where partially blocked fuel flow can cause the engine to stall, particularly at low fuel levels. On the visibility side, vehicles equipped with the optional Surround Vision feature may have a rearview camera with a poorly crimped cable connector, causing the camera to fail or cut out intermittently while backing up.
