Owners of 2022 Tundras are reporting widespread electrical system problems spanning multiple subsystems. The most serious involves roof seam corrosion and water intrusion into the A-pillar area, where airbag wiring and squib connectors are exposed to moisture every time it rains—a failure that Toyota dealers have repeatedly observed but not resolved.
Dashboard and infotainment issues are common: digital instrument clusters freeze or black out while driving, fuel gauges reset to full without refueling, and distance-to-empty readings malfunction despite Toyota issuing a technical service bulletin. Owners report these problems persist into 2024 model year trucks.
Safety-critical system failures include complete engine shutdowns while driving on highways, stalling during acceleration from stops, and a front view camera that fails and causes sudden braking. One owner reported total system failure (engine, hybrid, brakes, parking brake) simultaneously at 2,000 miles. Pre-collision system, secondary brake system, and parking brake warnings appear without clear cause.
Smaller but troublesome failures include driver door lock actuator failure, front active spoiler motor repeatedly failing days after warranty replacement, digital rearview mirror cutouts at highway speeds, hood latch sensor giving false "open" alerts with constant beeping, and passenger camera mounts falling off on highways.
Parts availability is a persistent complaint—window motors and roof components sit unavailable for weeks or months, and some recall parts have been outstanding for nearly a year.
Failure modes owners describe
Roof Seam Corrosion & Water Intrusion into Electrical/Airbag Systems
Front driver-side roof seam developed corrosion under paint and opened, allowing rainwater to enter the cabin and drip directly onto A-pillar area, curtain airbag wiring, squib connector, and dashboard electrical controls. Interior rust staining observed. Occurs every time it rains.
