Vehicles with a 6speed automatic transmission may develop one or more of the following faults related to a broken 35R clutch wave plate inside the transmission: Illumination of the Check Engine Light with code P0716, P0776, P0717, P0777, P2714, P2715, and/or P02723, loss of reverse gear, slipping or harsh 3rd or 5th gear shift. Removal and dis-assembly of the transmission will be required to replace the broken 35R wave plate. It is also extremely important that all debris from the failed part be cleaned from the transmission while it is disassembled in order to try and prevent future problems.

These are sometimes the result of low brake fluid, but no obvious leaks are noted. Due to the design of the master cylinder and brake booster, the master cylinder can leak from the rear seal and collect inside the booster, leaving no drops on the ground or obvious signs.

A Loose or worn gas cap may cause Check Engine Light to illuminate.

Increased resistance in the front seat mounted side impact air bag (SIAB) wiring harness can result in the SIAB and seat belt pretensioners not deploying as expected in the event of a crash, increasing the risk of personal injury. Dealers will replace the affected harness connections with soldered connections to correct this concern.

The heated washer module under the hood could overheat due to excessive current draw. Under certain conditions, this could result in an under hood fire.

This recall is expected to begin on June 20, 2010.
