The hazard
On certain vehicles, the bolts used to secure the housing and sprocket of the intake-side Variable-Valve Timing (VVT) gear assembly could loosen. If this occurs, the VVT gear will not control the intake valves correctly. In some instances, the VVT gear housing and sprocket could separate, causing the engine to stall. Engine stalling would result in a loss of vehicle propulsion which, in conjunction with traffic and road conditions, and the driver’s reactions, could increase the risk of a crash causing property damage and/or personal injury. Correction: Dealers will replace the VVT unit with an improved version.
