Volvo Trucks North America is recalling certain 23,000 2007-2014 VAH, VHD, 
VNL, VNM, and VT models because of an omission that could lengthen stopping 
distances. The affected vehicles were manufactured from December 20, 2006 
through May 22, 2013.

A National Highway Traffic Safety Administration bulletin says the affected 
vehicles were built without a redundant clutch disengagement switch.

Without a redundant switch, a loss of signal from the brake air pressure 
switch can prevent the clutch from automatically disengaging when the brake 
is applied. Without a signal to disengage the clutch when the brakes are 
applied, the distance required to stop the truck may lengthen, increasing 
the risk of a crash.

NHTSA's Office of Defects Investigation says it is aware of 134 of these 
vehicles with one or more complaints or field reports related to this 
condition and is aware of 164 with one or more warranty claims related to 
this condition.

All suspect trucks were originally equipped with automated manual 
transmissions. According to Volvo, reports of the subject transmission 
clutch mechanism failing to automatically disengage as intended are 
associated with the removal of a brake pedal micro switch that provided a 
redundant signal to the transmission control module indicating the brakes 
had been applied. Previously, Volvo had removed this brake pedal micro 
switch from new vehicle production and from certain vehicles already 
in-service via two field service campaigns because it decided the switch was 
unnecessary and/or a maintenance issue.

in the absence of this redundant brake pedal micro switch, the clutch 
mechanism may fail to disengage the transmission from the engine at low 
vehicle speed should the stop lamp switch fail to send and/or the 
transmission control module fail to receive the primary signal.
