This page covers 4 recalls, 50 owner complaints and NHTSA crash-test ratings for the 2020 Chevrolet Tahoe.
4/5 Overall
NHTSA 5-Star Safety Rating
The 2020 Tahoe draws complaints spread fairly evenly across the engine, powertrain, and electrical systems. On the powertrain side, owners frequently report transmission failure, some at relatively high mileage, others describing the failure alongside unusual diagnostic codes that complicate the repair. Engine complaints include shaking and severe hesitation while driving, with the 6.2-liter engine mentioned by name in some reports. Electrical system complaints overlap with both: sudden loss of power steering is a recurring theme, with owners describing complete loss of steering control and a warning light appearing simultaneously. A separate pattern involves brake assist failure tied to the vacuum brake pump, where the pedal becomes extremely hard and braking effectiveness drops sharply. A handful of owners also describe air conditioning problems, specifically refrigerant leaks causing the system to stop cooling.

By System
The 2020 Chevrolet Tahoe has 4 recalls, the most serious including a fuel system defect where a missing pressure regulator can crack the fuel pump and cause a fuel leak that may ignite near a heat source.
On the brake and drivetrain side, certain Tahoes equipped with a 5.3-liter engine, 3.08-ratio rear axle, and four-wheel drive have a driveline-protection sensor that can activate unexpectedly, causing the brakes to pull hard to one side without warning. A separate transfer case defect on four-wheel and all-wheel drive models can cause front or rear wheels to lock up, raising the risk of losing control. There is also a tire concern: Continental tires on certain vehicles may have been over-cured during manufacturing, which can cause the sidewall to crack or the tread to separate from the belt, leading to a sudden blowout.
