Over-the-air update ACM-25.3.3 Nautilus

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

SSM 521252023-12-11. Service bulletin. Some 2024 Nautilus vehicles may exhibit diagnostic trouble code (DTC) U3000:49 in the camera module-rear (CMR) when a diagnostic self-test is performed. This may be due to the system triggering a shared variable and then enters a timeout reset process. The history state DTC U3000:49 has no effect on functionality. Replacement or reprogramming of the CMR will not resolve this condition. Engineering is currently working on a solution and a software update is expected in Q2 2024. Continue to monitor OASIS for additional information.
