The hazard

On certain vehicles, a defect in manufacturing could result in a loss of oil supply to the vacuum pump. If this were to occur, the vacuum pump could fail, causing a loss of power assist to the braking system. This could cause increased stopping distances, possibly resulting in a crash causing injury and/or damage to property. Correction: Dealers will install a camshaft seal disk locking ring.
