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.

- [B120626](/bulletins/11034450.md), 2026-07-03, Service campaign: ELECTRICAL SYSTEM. In these vehicles with an S68 engine, an incorrect diagnosis of the Valvetronic \(VVT\) may occur. Undercertain operating conditions, the software may detect a short\-circuit in the valve control system even thoughthere is no fault. When the above\-mentioned fault occurs, the red Check Control warning light ‘Drive system fault’ illuminates.This can result in the intake valves closing gradually, which may lead to misfires while the engine is running.
