EquipmentDec 15, 2017 · NHTSA campaign 17V809000 · 34,699 vehicles

Problem: Newmar Corporation (Newmar) is recalling various 1995-2018 motorhomes. A list of the affected vehicles available at: https://static.nhtsa.gov/odi/rcl/2017/RMISC-17V809-2309.pdf. These motorhomes are equipped with Kidde Plastic-Handle or Push Button 'Pindicator' Fire Extinguishers that may become clogged, preventing the extinguisher from discharging as expected or excessive force may be needed to activate the extinguisher. Additionally, in certain models, the nozzle may detach from the valve assembly with enough force that it could cause injury and also render the product inoperable. For a full list of the affected fire extinguisher models visit: https://static.nhtsa.gov/odi/rcl/2017/RMISC-17E062-5427.pdf

Risk: In the event of a fire, if the fire extinguisher does not function properly, it can increase the risk of injury.

Fix: Newmar will notify owners, and instruct them to contact Kidde for a replacement fire extinguisher, free of charge. The recall began on February 7, 2018. Owners may contact Kidde customer service toll-free at 1-855-262-3540, or online at www.kidde.com and click on "Product Safety Recall" for more information or owners may contact Newmar customer service at 1-574-773-7791.

Vehicle speed control:accelerator pedal; engine and engine cooling:engineJun 28, 2016 · NHTSA campaign 16V478000 · 1,243 vehicles

Problem: 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.

Risk: 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.

Fix: 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.

Steering:hydraulic power assist:hose, piping, and connectionsMay 10, 2016 · NHTSA campaign 16V280000 · 93 vehicles

Problem: Newmar Corporation (Newmar) recalling certain model year 2014-2015 Essex, and 2015 Mountain Aire and London Aire motorhomes manufactured from May 20, 2013, through April 09, 2015. These vehicles are built on Freightliner rear engine chassis that have 18,000lb or 20,000lb-capacity front axles. In these motorhomes, the power steering fluid temperature may exceed the power steering hose material rating, subsequently causing the hoses to fail, resulting in a sudden loss of power steering.

Risk: Loss of power steering assist would result in increased difficulty to steer the vehicle in either direction at low speeds, increasing the risk of a crash.

Fix: Newmar will notify owners, and Freightliner dealers will replace the power steering hose with a higher temperature rated one, free of charge. The recall began on June 15, 2016. Owners may contact Freightliner customer service at 1-800-547-0712 or Newmar customer service at 1-800-731-8300. Newmar's number for this recall is 16V-121.

Service brakes, hydraulic:pedals and linkagesApr 28, 2016 · NHTSA campaign 16V252000 · 1,150 vehicles

Problem: Newmar Corporation (Newmar) is recalling certain model year 2014-2016 Dutch Star, Mountain Aire, Essex, and 2015-2016 London Aire vehicles manufactured March 27, 2013, to October 16, 2015 and built on a Freightliner chassis. On certain recreational vehicles built with a heavier, adjustable foot pedal, the brake activation signal to certain towed devices may not deactivate when the service brakes are released.

Risk: If the brake activation signal to a towed device remains active when the motorhome chassis service brakes are released, the brakes on a towed device may remain engaged depending on brake configuration of the trailer. As a result, the brakes would drag and possibly overheat potentially resulting in a fire. Additionally, following drivers may be confused by the motorhome's actions, increasing the risk of a crash.

Fix: Newmar will notify owners, and Freightliner dealers will modify the affected assemblies, free of charge. The recall began on May 26, 2016. Owners may contact Freightliner/Daimler Trucks North America LLC at 1-800-547-0712 or Newmar customer service at 1-800-731-8300. Newmar's number for this recall is 16V-204.

The affected vehicles are equipped with refrigerator door latches that may inadvertently lock without the operator's knowledge.

Risk: If an individual climbed into the refrigerator and the door inadvertently latched, the person would not be able to open the door, increasing their risk of injury.

Fix: Newmar will notify owners, and dealers will install a new replacement door latch that will not automatically latch, free of charge. The recall began on January 24, 2016. Owners may contact Newmar customer service at 1-800-731-8300.
