2022 Chevrolet Tahoe Reliability Report

Water leaks and OnStar failures dominate. After rain, water sloshes in the headliner and pours from seat belt slots, roof vents, dome lights, and the overhead console, soaking seats and carpet. Dealers have found clogged sunroof drains, and leaks return after repair. OnStar modules fail early and stay back-ordered, with some owners asked to pay once warranty lapses. Other reports include a passenger grab handle that snapped and caused an injury, a sunroof that shattered while driving, a no-power condition with a stuck start button, and a faulty backup camera.

Stalling without warning is the main risk, often traced to a failed fuel pump control or driver module. The engine quits while driving or idling and will not restart, sometimes leaving the truck stuck in traffic without steering assist. One report notes the 2021 model had a recall for the same module. Other complaints describe sudden power loss on a freeway ramp, injector misfires on the L87 engine even after a recall engine replacement, and a broken plastic diesel filler neck that spills fuel.

Brake squeal accounts for most reports, a noise issue rather than a stopping failure. Two reports are far more serious. At startup, the dash shows a brake system failure message along with ABS, stability, and traction warnings, and the pedal either sinks to the floor or stays firm without stopping the truck. Both happened at low speed in a parking situation. Dealers could not duplicate the fault once the warnings cleared.

Most reports tie back to federal recall campaign 25V274000. Symptoms include loss of power, violent shuddering, stalling at lights and turns, metal-on-metal rattling, and metal shavings in the oil pan that lead to engine replacement. Oil consumption also appears, with a quart added monthly in one case and inconsistent oil-level test results in another. Several owners say recall parts were not yet available. Others were told their VIN was not covered despite matching symptoms. One failure came at 100,000 miles.

Roof and windshield leaks are the whole story here. Rainwater collects in the headliner and pours from the overhead console, seat belt slots, and rear vents onto the dash, phone charger, and driver's feet. Leaks start as early as 2 months after purchase. Dealers have removed windshields and headliners and found defective factory welds, yet several leaks return after the next rain. Repeated soaking raises concerns about corrosion and damage to overhead electronics.

Headrests that will not lock upright are the main complaint. Second-row captain's chair headrests fail to latch after the seat is folded and returned, and a third-row headrest bends forward so the seat cannot be used. In one case a dealer found a part needing replacement but did not repair it. A separate report describes the sliding front center console failing to lock when extended and shifting under light elbow pressure while driving.

Failure to deploy in a crash is the serious report here. In a high-speed collision with front and side impacts, the air bags did not deploy and the driver suffered a permanent shoulder injury. Another complaint describes a service safety restraint system warning that keeps appearing while driving. With only 2 complaints on file, the pattern is thin, but a non-deploying air bag is the most severe outcome in this category.
