2020 Newmar London Aire

UNKNOWN I was traveling in this new to me 2020 Newmar London Aire on a trip of approx. 2,700 miles. The first issue was coming to a bridge in SC that was maybe 400 feet in length. There were lots of transition strips and dips on the bridge. When I first approached the bridge, my Motorhome bounced/propoised so violently that my wife flew up out of her sit and the front end dropped to the stops on the frame. I have been MHoming since 1999 and have never experienced this type of bouncing. I was scared and the MH continued to bounce on this bridge for another 6-8 times, although not as violent as the first bounce. We experienced this bouncing/porpoising many other times on our trip, just not quite as violent as described above. This is a major safety issue and it has to do with improper shocks/ no sway bar on the front axle. The chassis is Spartan and I talked to them about the problem but they played dumb, even though I have communicated with many other MH owners who have experienced this same problem with this K3 Spartan Chassis. Those owners have also talked to Spartan and have not gotten any satisfaction.

Incident

Sep 6, 2022

Newmar Corporation has decided that a defect, which relates to motor vehicle safety, exists in specific motorhomes built on Freightliner and Ford Chassis. On certain Newmar Class A motorhomes, the wiring under the seats may be incorrectly secured, which may lead to a pinched wire in the seat/slide adjustment mechanism.

The Shyft Group Inc. (Spartan Chassis) has decided that a defect relating to motor vehicle safety exists in specific motorhomes built on Spartan chassis (NHTSA #21V 752). In response, Newmar Corporation is issuing recall NHTSA # 21V 822 and TC # 2021-640. On certain motorhomes built on a Spartan chassis, a defect in the power steering pump could cause it to fail. If this happens, there could be a loss of power steering assist. This could increase the risk of a crash.

The Shyft Group Inc. (Spartan Chassis) has decided that a defect relating to motor vehicle safety exists in specific motorhomes built on Spartan chassis (NHTSA #21V 589). In response, Newmar Corporation is issuing recall NHTSA # 21V 700 and TC # 2021-551. On certain motorhomes, under certain conditions, the instrument cluster may intermittently go blank for a brief period of time while the vehicle is in motion. Gauge data or indicators may appear to be delayed or slow to update prior to the instrument cluster going blank. Without the instrument cluster displaying important information such as the vehicle's speed, there may be an increased risk of a crash.

Newmar Corporation has decided that a defect relating to motor vehicle safety exists in specific motorhomes. Lippert (Newmar’s window supplier) is recalling Hehr 6400 series window vents (Lippert recall 21E 047) built between 10/01/2018 and 08/13/2020, which were used on various coach models during the affected period. The adhesive that bonds the vented portion of the window may fail. Adhesive failure may cause the vent portion of the window to detach, increasing the risk of a crash or injury.

On certain motorhomes built on a Spartan chassis, the steering gear mounting fasteners may come loose and fall out or interfere with other steering components. If the steering gear mounting fasteners interfere with other steering components, such as a pitman arm, it may cause difficulty in steering or pin the steering wheel to one direction, which could increase the risk of a crash.

Riverpark discovered that a firmware update may be needed on Xite infotainment systems installed on select 2020 Newmar coaches. The affected Xite systems were shipped to Newmar prior to March 16, 2020.
