2006 KENWORTH T800 Recalls (13)

Campaign:
05V543000 on 11/28/2005
Component:
Steering
Manufactured:
06/30/2004 - 11/14/2005
Affected:
241
Defect:
On certain trucks equipped with the bendix electronic stability control (esp) system, the system uses multiple sensors and an electronic control unit (ecu) to control vehicle under steer, over-steer, and rollover situations. the system relies on vehicle sensors to be functioning and aligned properly. the steering angle sensor has the potential to be misaligned with the steering column shaft, thereby providing incorrect information to the bendix ecu.
Consequence:
This condition could affect vehicle throttle control and braking, thereby leading to loss of vehicle steering control which could cause a crash without warning.
Correction:
Because of the immediate and substantial risk, kenworth and peterbilt dealers will first deactivate the yaw control feature of the bendix esp system preventing inadvertent esp activation. when parts are available, the steering column will be replaced to insure proper alignment of the steering shaft sensor and the full esp system will be reactivated. the recall began on december 7, 2005. parts to complete the remedy are estimated to be available in early 2006. owners may contact kenworth at 1-425-828-5440 or peterbilt at 1-940-591-4201.

Component:
Trailer hitches:fifth wheel assembly
Manufactured:
10/01/2006 - 10/26/2006
Affected:
86
Defect:
On certain trucks, an ra529 king pin release air valve was manufactured with the internal spool installed backwards. this results in the air option of the king pin release system being inoperable. to correct this situation, the vehicle's air lines were reversed rather than replacing the valve.
Consequence:
With the lines reversed, the king pin can be released without the driver's knowledge. when this occurs, the driver could drive away and the trailer could become disengaged, increasing the risk of a crash.
Correction:
Kenworth will inspect the king pin release system and suspect valve. if any vehicles have a nonconforming valve or incorrect plumbing, it will be replaced and re-plumbed. the recall began on november 29, 2006. owners may contact kenworth at 1-425-828-5440.
