Recalls, owner-reported complaints, investigations and safety data

Data refreshed

Owner complaintsComplaints are reports submitted to NHTSA by owners and drivers. NHTSA does not verify most reports before publishing them, and a complaint does not establish that a defect exists. Volume is influenced by how many of a vehicle were sold, how long it has been on the road, and how much attention an issue has received.

Safety recallsA safety recall is issued when a manufacturer or NHTSA determines that a vehicle has a safety-related defect or does not comply with a federal motor vehicle safety standard. Recall repairs are free. Whether a specific vehicle is covered depends on its VIN — a recall listed for a model year does not necessarily apply to every vehicle of that year.

Latest Dec 15, 2017
InvestigationsNHTSA opens an investigation to examine whether a safety defect may exist. An open investigation is not a determination that a defect exists, and many investigations close without a recall. Investigations can, however, lead to one.

34,699 units potentially affected
The defect: 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
The risk: In the event of a fire, if the fire extinguisher does not function properly, it can increase the risk of injury.
The remedy: 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. Newmar's number for this recall is 17E-062.

1,243 units potentially affected
The defect: 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.
The 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.
The 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.

May 10, 2016
93 units potentially affected
The defect: 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.
The 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.
The remedy: 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.

I PURCHASED THE UNIT WITH 25,000 MILES. THE DEF SYSTEM FAILED ENROUTE TO THE DEALER I PURCHASED IT FROM AND FAILED AGAIN AFTER APPROXIMATELY 3,000 MILES AFTER REPAIR. THE ENTIRE DEF HEADER WAS REPLACED. THIS IS AN EXTREMELY DANGEROUS SITUATION WHEN THE VEHICLE GOES IN TO DERATE. MY MOTORHOME IS 53,000 LBS AND 45'. ADD A TOW VEHICLE AND IT IS VERY DANGEROUS WHEN THIS HAPPENS. I WAS HEADING TO LAS VEGAS NV FROM QUARTZITE, AZ WHEN THIS HAPPEND ON A TWO LANE HIGHWAY. NO PLACE TO PULL OVER TO EVEN CHECK ANYTHING. THESE DEF SYSTEMS CONTINUE TO BE EXTREMELY PROBLEMATIC. THERE NEEDS TO BE INVESTIGATION IN TO HOW TO KEEP THESE SYSTEMS OPERATING PROPERLY.

EQUIPMENT:MECHANICAL

Check for proper torque of all mounting bolts on all electric slideout motors. If any bolt is under- torqued, remove the bolt, and add blue LOCTITE® thread sealant to the bolt threads. If there is no washer on the nut side of the bolt, add a flat washer. Reinstall and torque all 5/16” bolts to 19 ft. lbs. and all 3/8” bolts to 33 ft. lbs.

ELECTRICAL SYSTEM; EQUIPMENT ADAPTIVE/MOBILITY

Newmar has made a change to the water pump circuit fuse on certain coaches to improve customer experience. In most cases, the 10 amp fuse installed by the factory is sufficient. However, some coaches equipped with a ShurFlo water pump (Newmar part # 127488) blow the 10 amp water pump fuse.

FUEL SYSTEM, GASOLINE; FUEL SYSTEM, GASOLINE:STORAGE:AUXILLARY TANK; STEERING; WHEELS

Daimler Trucks North America LLC, on behalf of its wholly-owned subsidiary, Freightliner Custom Chassis Corporation, has issued field service campaign SF546AB. In response, Newmar is publishing PIB 495. Issue: On certain coaches, a check valve is missing on the auxiliary air tank, causing the tag axle steer tires to remain in a turned position when stopping the vehicle during a turn and shifting into reverse. In addition, some of these vehicles also require an air line retrofit.

PIB 494

EQUIPMENT

If the coach's HWH leveling system has intermittent issues when operating, check for corrosion or loose mounting bolts. Torque the mounting bolts (if needed) to 30 ft. pounds. A ground cable may also be installed to improve the overall grounding of the HWH pump assembly.

TSB 493

ELECTRICAL SYSTEM; ELECTRICAL SYSTEM: INSTRUMENT CLUSTER/PANEL; ENGINE

Daimler Trucks North America has issued field service campaign SF543A. In response, Newmar is publishing TSB 493. Issue: On specific vehicles equipped with Stoneridge light bar control units (LBCU), the instrument panel odometer value may reset and no longer match the engine ECU odometer value.

Manufacturers file copies of the bulletins they send to dealers with NHTSA. These often describe diagnostic or repair procedures for a known condition. They are not recalls: repairs described in a bulletin are usually only free if the vehicle is still under warranty or the manufacturer has extended coverage.
