Affects Pontiac Aztek, Montana, Montana SV6 · 2001–2007 — about 49K vehicles.
The hazard
On certain Aztek (AWD), Montana (AWD), Relay (AWD), RendezVous (AWD), RendezVous (FWD), Silhouette (AWD), Terraza (AWD), Terraza (FWD), Uplander (AWD) and Venture (AWD) vehicles equipped with independent rear suspension, when operated in extreme cold temperature and on rough roads, water and salt can intrude past the ball joint seal. The combination of theses conditions may then lead to premature wear of the ball joint. If the ball joint wear progresses to the point of separation from the lower control arm, a loss of vehicle control may occur. Correction: Dealers will replace both ball joints with new ball joints which have a revised boot and ball stud to improve the seal to the ball stud shaft.
