Known issues on the 2021 Escalade. Nine recalls are on federal record for this model year. The fuel pump control module can interrupt fuel flow and cause an unexpected engine stall. Rear driveshaft components that weren't properly heat-treated can fail, cutting drive power without warning. A communications gateway fault can keep the air bag malfunction lamp from lighting when it should. Third-row seat belts may have been entrapped or misrouted behind the seat-folding mechanism, and a deformed rivet in the third-row buckle assembly may not properly restrain an occupant in a crash. A lighting control module software error can leave the daytime running lights on with the headlights, creating glare for oncoming traffic. On diesel-equipped trucks, a transmission control valve fault can lock the rear wheels, and an incorrect fuel tank can leak in a rollover. On 6.2L V8 trucks, connecting rod or crankshaft defects can lead to engine failure. Owners have filed 82 complaints for the year. The factory diagnostic and repair procedures behind each of those systems are here.
From a fuel pump or driveshaft diagnosis to a third-row seat belt inspection or a diesel transmission control valve check, it keeps you on the OEM procedure and the correct specification for your specific 2021 Escalade.
