BMW of North America and the National Highway Traffic Safety Administration have announced a recall for 2019 Rolls-Royce Cullinan models in the U.S.

The report published by the NHTSA reveals that approximately 454 Cullinan models built between December 1, 2018 and July 18, 2019 may not fully confirm to FMVSS 108 (lamps, reflective devices and associated equipment) Section 7.3.13.1 and Table IX. In layman’s terms, this means the taillights may not have been manufactured according to specifications due to variations in the supplier’s production process and are not bright enough.

The NHTSA says that the dull taillights could impair road users driving behind an effected Rolls-Royce Cullinan and increase the risk of a crash.

Rolls-Royce discovered the issue in late July after testing. It then reviewed a supplier’s manufacturing process and later discovered that a few hundred Cullinan models may be affected. The British carmaker has not received any reports of accidents or injuries related to the issue.

The recall notice confirms that owners will be notified by first class mail and instructed to take their vehicle to an authorized dealership. Any repairs that need to be carried out on affected vehicles will be free of charge as they will be covered by the vehicle’s warranty.

It’s not entirely clear exactly how many vehicles are affected by the recall. One safety report from the NHTSA states that 422 units are potentially involved while also stating that approximately 454 Cullinan models may not fully conform to the aforementioned regulations. A separate report from the NHTSA says 403 units are potentially affected. We have reached out to Rolls-Royce for confirmation.
