NHTSA's recall notice
As NHTSA's recall record states it for campaign 16V478000.
Defect description
Newmar Corporation (Newmar) is recalling certain model year 2014-2016 Dutch Star and Mountain Aire and 2015-2016 London Aire and Essex motorhomes manufactured January 28, 2013, to December 14, 2015 and built on a Daimler Trucks North America (DTNA) chassis. The throttle pedal position sensor on the affected vehicles may not return to zero, causing the engine brake to suddenly not activate as expected, reducing the vehicle's deceleration ability.
Safety consequence
A sudden loss of an engine brake without warning on a motorhome may lead to a reduced brake capacity, potentially increasing the risk of a crash.
Manufacturer remedy
Newmar will notify owners, and DTNA dealers will replace the throttle pedal, free of charge. The recall began on August 5, 2016. Owners may contact Newmar Customer Service Department at 1-800-731-8300 or Daimler Trucks North America LLC at 1-800-547-0712, or by e-mail at [email protected]. Newmar's number for this recall is 16V 321.
Notes
Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.safercar.gov.
