severe NHTSA 07E066000 August 28, 2007

Certain cequent 90 degree 7-way right angle adaptors sold by distributors in tow packages for aftermarket sales to tow 5th wheel rv travel trailers

severe NHTSA 06V417000 October 31, 2006

Certain vehicles originally built with cloth seats that were equipped with an automatic air bag passenger sensing system and later reupholstered with aftermarket leather seat cover kits are involved

If the passenger sensing system malfunctions, the front air bag on the passenger side may be disabled when it should be enabled, or enabled when it should be disabled. In either case, in the event of a crash that requires air bag deployment, a front passenger's level of injury may be increased.

Fix: Because a replacement leather seat cover that is compatible with the passenger sensing system is not available, general motors (gm) will repurchase these vehicles in accordance with the terms stated in gm's letter to owners. The recall began on november 6, 2006. Owners should contact gm at 1-877-477-1022 to begin the process of repurchasing their vehicle.
