SERVICE BRAKES
Owners of the 2020 Chevrolet Tahoe report issues with the service brakes, including difficulty pressing the brake pedal, which becomes extremely hard, and subsequent alerts for "Brake Assist" and "Antilock Braking System" advising immediate service. Another complaint highlights significant flaking of the front rotors, specifically on the inside, at around 35,500 miles, with the outer surfaces remaining smooth. Additionally, the auto/power pedal height adjustment feature is noted for creating a problematic distance between the brake and gas pedals, potentially causing difficulty in engaging the brake pedal, especially for individuals wearing certain footwear.

FUEL/PROPULSION SYSTEM
Owners of the 2020 Chevrolet Tahoe report issues with the fuel/propulsion system primarily involving fuel injectors, fuel rails, and the high-pressure fuel pump. Common symptoms include the illumination of the check engine light, stalling, rough idling, trembling, and acceleration hesitation. These problems are observed around the 52,000-mile mark, with some owners noting corrosion and snapping of components, and others identifying a malfunctioning fuel pump. Safety implications are significant, as stalling at high speeds could lead to accidents, and a fuel odor in the oil suggests a potential risk of fire. Buyers should be aware of these issues, especially since some repairs are reportedly not covered under warranty due to build date discrepancies.
