Paccar is recalling more than 5,000 model year 2014 Kenworth T170, T270, T370, T440, T470, T660, T680, T700, T800, T880, C500 and W900 trucks, manufactured July 1, 2013 through Sept. 17, 2013.

In the affected vehicles, the plastic housing of the stop/tail/turn lamp can shrink, allowing the light bulb to fall out of the mounted retention ring, causing it not be illuminated.

In addition to this failing to meet Federal Motor Vehicle Safety Standard No. 108 "Lamps, Reflective Devices, and Associated Equipment,” this could also increase the risk of a crash.

Kenworth will notify owners, and dealers will replace the defective STT lamps with new lamps. The recall is expected to begin sometime this month.

Customers may contact Paccar at 1-425-468-7400. Kenworth's number for this recall is 13KWM.

Daimler Trucks North America is recalling 379 model year 2013-2014 Freightliner Cascadia trucks, manufactured Dec.11, 2012, through Nov. 27, 2013 that are equipped with Meritor Wabco’s electronically controlled air suspension system.

In the affected vehicles, the wiring harnesses for the ECAS may have been reversed. If the wiring harnesses are connected in reverse, it may adjust the suspension axle height incorrectly, reducing driving traction and parking brake effectiveness. Either result increases the risk of a crash.

DTNA will notify the owners, and dealers will inspect the ECAS wiring, correcting it as necessary, free of charge. The recall is expected to begin Feb. 16.

Owners may contact Daimler at 1-800-547-0712. DTNA's number for this recall is FL-656.
