2020 NEWMAR NEW AIRE Wheels Problems

The integrated Tire Pressure Monitoring System in this vehicle has never functioned correctly since it was purchased new in October, 2020. The system either drops connection fully, drops various tires on the coach, or randomly alarms for extreme high/low temperature and pressure. In August of 2021, the vehicle was driven 1600 miles to Newmar’s factory in Indiana for warranty repairs. The TPMS was on that list. Newmar disavowed all warranty responsibility for the system and its failures, and directed us to Freightliner. The RV has been returned to Doggett Freightliner in El Paso, TX multiple times since 2020 for recall repairs on the Tire Pressure Monitoring System. The last repair attempt was in January 2023 for Freightliner recall 9. This recall was not completed due to unavailability of repair parts. Doggett Freightliner has not responded to any of my calls since, and the repairs have yet to be completed. On...

The Valor TPMS system on the Freightliner chassis has not worked correctly for as long as I have owned the coach. I was hopeful that recent recall work performed by a Freightliner service center on the system would help but it actually made the system worse. As was prior to the recall work several of the sensors still fail to report their pressures completely, others report only sporadically. This essentially renders the system useless as the driver may not be made aware of a loss of tire pressure while driving. Additionally, since the recall work was performed, a high pressure warning now displays when the tires heat up in normal driving conditions. This warning is distracting and appears separately for each tire. When the warning appear it blocks the digital speedometer and other vital information on the dashboard from displaying until the warning is cleared manually.
