Overview

2021 Rolls-Royce Cullinan

The 2021 Rolls-Royce Cullinan offers unparalleled luxury and presence, but as a used purchase, its mechanicals and potential issues warrant careful consideration. While consumer complaints are absent, three recalls, primarily concerning the passenger seat belt Automatic Locking Retractor (ALR), highlight a specific component concern. This defect could compromise occupant restraint in certain scenarios. Beyond this, the 12-cylinder, 6.7-liter engine and its automatic transmission are expected to perform reliably, provided the vehicle has been maintained to Rolls-Royce standards. Fuel economy is predictably low, with a combined rating of 14 MPG.

Critical Failure Risk

The passenger seat belt's Automatic Locking Retractor (ALR) may deactivate prematurely, failing to provide proper restraint in certain situations. This is a safety-critical component.

Early detection can help you avoid a $300-$700 repair.
