Known issues on the 2020 Tahoe. Three recalls sit on the record. One involves a fuel pump built without its pressure regulator, so the fuel system can over-pressurize until the pump cracks and leaks near a possible ignition source. Another covers tires cured too long, which can break in the sidewall and lose air suddenly or shed a belt and its tread. The third is the wheel-speed sensor fault that turns the driveline protection system into unintended braking on the opposite wheel. Complaints are light at 55, with the power train at 13 and the engine and electrical system at 9 each.
