NEWMAR NEW AIRE

STEERING:CRITICAL FASTENERS

Newmar Corporation (Newmar) is recalling certain 2021-2022 New Aire, Essex, King Aire, Ventana, Kountry Star, London Aire, Dutch Star and Mountain Aire motorhomes. The upper bolt connecting the steering column may not have been properly tightened, causing the nut to loosen off the bolt, potentially resulting in loss of steering control.

Risk: Loss of steering control increases the risk of a crash.

SEATS

Newmar Corporation (Newmar) is recalling certain 2019-2022 Bay Star, Bay Star Sport, Ventana, Dutch Star, New Aire, Canyon Star, 2019 Ventana LE, 2020-2022 Kountry Star, 2019-2020 Mountain Aire, London Aire, Essex, and 2021 Super Star vehicles. The wiring under the seats may be incorrectly secured, which can lead to a pinched wire in the seat adjustment mechanism and cause an electrical short circuit.

Risk: A short circuit increases the risk of a fire.

FUEL SYSTEM, DIESEL:FUEL INJECTION SYSTEM:FUEL RAIL

Newmar Corporation (Newmar) is recalling certain 2017-2022 Dutch Star, 2017-2019 Mountain Aire, 2019-2021 Ventana and 2021 New Aire motorhomes. The sealing washer may not seat correctly in the pilot bore holes, allowing the high pressure fuel rail assembly to leak.

Risk: A fuel leak in the presence of an ignition source increases the risk of a fire.

ELECTRICAL SYSTEM: INSTRUMENT CLUSTER/PANEL

Newmar Corporation (Newmar) is recalling certain 2019-2021 London Aire, Dutch Star, Essex, King Aire, Mountain Aire, 2020-2021 Ventana, and 2021 New Aire recreational vehicles. The instrument cluster may intermittently go blank while the vehicle is in motion.

Risk: A blank instrument cluster display may be missing critical information such as the vehicle's speed and warning lights, which can increase the risk of a crash.

SERVICE BRAKES, AIR:ANTILOCK

Newmar Corporation (Newmar) is recalling certain 2021 Dutch Star, New Aire, and Ventana motorhomes. The adjustable brake pedal assembly may be missing a return spring. This may cause the brake lights to stay illuminated after the brake pedal is released. Also, in certain towed vehicles, the brakes may stay engaged after the brake pedal is released.

Risk: Malfunctioning brake lights can fail to alert other motorists of the driver's intention, increasing the risk of a crash. Additionally, brakes remaining unintentionally engaged on a towed vehicle can increase the risk of a crash.

The adhesive that bonds the vented portion of the window may fail.

Risk: Adhesive failure may cause the vent portion of the window to detach, increasing the risk of a crash or injury.

STEERING:COLUMN

Newmar Corporation (Newmar) is recalling certain 2021 London Aire, Dutch Star, New Aire, Ventana, and Mountain Aire vehicles. The steering output shaft may be too short and could disengage from the steering input shaft.

Risk: Disengagement of the steering output shaft may result in a loss of steering, increasing the risk of a crash.

FUEL SYSTEM, DIESEL:DELIVERY:HOSES, LINES/PIPING, AND FITTINGS

Newmar Corporation (Newmar) is recalling certain 2021-2022 Dutch Star, New Aire, and Ventana vehicles equipped with Cummins L9 diesel engines. A fuel leak may occur from the fuel hose between the fuel pump and the remote fuel filter head.

Risk: A fuel leak in the presence of an ignition source increases the risk of a fire.

STRUCTURE:BODY

Hinge failure on bay door. It is a common problem and has failed 3 times so far. The "C" clamp on the hing fails which causes the bolt to fall out and door to fall off. Newmar employees have stated that this is a poor design. Door falls off and the motorhome cannot be driven until fixed. It opens while driving going down the road, which could cause a serious accident. We are paying for yet another mobile rv repair to come out today and fix if possible.

VISIBILITY:GLASS, SIDE/REAR

During recent operation of the vehicle, the passenger-side front vent window failed to remain secure due to an apparent adhesive failure. The latch mechanism detached from the glass or frame, causing the window to become loose and unable to latch properly. This defect created a risk of the window fully detaching while driving, which could have led to a hazardous situation for vehicle occupants or other road users. No injuries or accidents occurred, but the issue significantly compromises vehicle safety. I am aware of NHTSA Recall 21V-571, issued in 2021, which addresses adhesive failure in Hehr 6400 series vent windows on 2019-2021 Newmar New Aire models, produced between October 1, 2018, and October 21, 2021. The symptoms observed in my 2018 model closely match those described in the recall, indicating that the same defect may affect earlier model years not currently included. To assist NHTSA’s investigation, I am prepared to provide additional documentation, such as photographs of the defective window, or facilitate an inspection of the vehicle if required. I respectfully request that NHTSA evaluate this complaint, collect reports from other 2018 Newmar New Aire owners who may have encountered similar issues, and expand Recall 21V-571 to cover the 2018 model year to mitigate potential safety risks. Thank you for your attention to this matter. Please contact me at the provided contact information for any further details or clarification.

VISIBILITY:GLASS, SIDE/REAR

On June15, 2025, the passenger’s side vent window glass partially delaminated from the actuator assembly while driving, damaging the actuator and window glass. The front passenger window has never sealed properly since we purchased the RV new. Newmar was notified of this in August 2021, when the coach was returned to Nappanee, IN for warranty repairs. After the window failure, I discovered that Lippert/Newmar issued an NHTSA Recall for these windows on September 8, 2021. The recall notes the issue as being: “the adhesive that bonds the vented portion of the window may fail. Adhesive failure may cause the vent portion of the window to detach…”. We did not receive this recall notice from Newmar. This window, part number 757205, is covered under Lippert HEHR6400 Series Window Vent Recall, NHTSA recall number: 21E047. I contacted Lippert immediately following the window failure on June 16, 2025. After being provided photographic documentation of the window failure, as well as confirmation of the defective part number, Lippert issued case number: 5952303. On June 18, 2025, Lippert instructed me to contact the OEM (Newmar) to arrange inspection and repair of the recalled window with an authorized dealer. On June 18, 2025, I contacted Newmar, who denied responsibility for the recall defect claiming the window had been inspected in August of 2021. When I informed Newmar that I would be filing a complaint with the NHTSA, I was issued a Newmar case number: 00989760. Since June 18, 2025, I have contacted every authorized Newmar Dealer within a 250 mile radius, providing them with: the recall information, Lippert and Newmar case numbers, and the part number for the recalled defective window. To date, no dealership has responded or even contacted Newmar for authorization. On July 9, 2025 I again attempted to contact Newmar to progress the matter and have yet to receive any form of reply. My experience with Newmar is that this recalcitrance is the norm.

The contact owns a 2021 Newmar New Aire RV. The contact stated while driving at an undisclosed speed, the instrument cluster failed to function as intended. The contact stated that the instrument cluster was distorted with moving bubbles inside. The contact stated that due to the failure it was difficult to read the screen. The dealer was made aware of the failure. The RV was not diagnosed or repaired by an independent mechanic or the dealer. The manufacturer was made aware of the failure but provided no assistance. The failure mileage was approximately 15,000.
