2007 KENWORTH T800 Recalls (21)

Campaign:
06V446000 on 11/26/2006
Component:
Vehicle speed control:cruise control
Manufactured:
10/10/2006 - 10/16/2006
Affected:
116
Defect:
An incorrect switch was installed in the cruise control system on certain model t300 trucks.
Consequence:
A light application of the brakes will not deactivate the cruise control and the system will have to be shut off by the dash switch. this could lead to unintended acceleration and a crash without warning.
Correction:
Kenworth will install the correct sensor switch. the recall began on january 10, 2007. owners may contact kenworth at 1-425-828-5440.
Notes:
Kenworth recall no. 06kw4.customers may also contact the national highway traffic safety administration's vehicle safety hotline at 1-888-327-4236 (tty 1-800-424-9153), or go to http://www.safercar.gov.

Component:
Steering:column
Manufactured:
06/05/2006 - 11/08/2006
Affected:
443
Defect:
On certain trucks equipped with a trw tilt/telescoping steering column, the tilt locking mechanism on the steering column may disengage. this could prevent the steering column from locking in to predetermined positions.
Consequence:
Should the locking mechanism disengage, the tilting travel of the column would be unrestricted. this unrestricted travel allows the steering wheel to impact the dash and could limit the movement of the steering wheel potentially resulting in difficulty maneuvering the vehicle, increasing the risk of a crash.
Correction:
Dealers will replace the tilt locking mechanism with a revised design that incorporates a new bracket for restraining the tilting mechanism. the recall began on december 22, 2006. owners may contact kenworth at 1-425-828-5440.
