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.
TSB 479
Newmar Corporation has decided that certain coaches built on a Freightliner chassis and equipped with Equalizer leveling jacks may have air bags that do not inflate correctly during jack retraction, which could cause air depletion from the air bags. Issue: Equalizer recommends starting the coach and allowing the chassis air pressure to build before pressing the ?All Retract? button to ensure adequate air supply to the chassis air valves. Failure to start the engine and pressurize the air system may contribute to the improper inflation of the air suspension system. Do not drive the unit without the air suspension system fully inflated. If for any reason the suspension is deflated, operate the ?All Retract? function on the jack panel while the coach is parked with the air tanks at full pressure.

Mailing second notice on not corrected customer letters on NHTSA Recall9/5/2017 Newmar Corporation has decided that a defect which relates to motor vehicle safety exists in specific motor homes built on Freightliner chassis. This recall is the result of information provided to Newmar by Daimler Trucks North America. NHTSA# 16V 481 TC# 2016-324 Issue: On certain motor homes manufactured by Newmar Corporation, the windshield wiper system is not operating as designed and has the potential to produce four separate issues. 1) The wiper arm may not park in the same location every time. 2) In high torque conditions such as a dry windshield, the wiper motor can stall. 3) When the wipers are turned on for any reason other than wash, the headlights would turn off when the wipers were turned off. 4) There are conditions where the wiper controls would put the motor in high with the first press of the Hi/Lo button where it should always go to low after a key cycle. If the wiper system is not performing correctly it could potentially increase the loss of control of the vehicle resulting in a crash.
