Active Curve System Oil Reservoir Leaks Oil Creating Fire Hazard

Recall Details

Oil may foam and leak out of the vent holes of the reservoir for the Active Curve System, creating a fire hazard. Dealers will correct the oil level as necessary and replace the reservoir sealing cap to prevent oil foam from leaking out free of charge to resolve the concern.

Our Quick Take

For vehicles equipped with the Active Curve System (ACS), oil may foam and leak out of the vent holes of the reservoir cap. This creates a fire hazard.
