2022 Newmar London Aire

The TPMS system fails to read tires while in motion. Primarily affects the rear outer drive axle, but all wheels, including front are impacted at random intervals. When standing still, the sensors will all read and display temperature and pressure. After driving for 10 minutes, a TPMS alert will display on the dash and one or more wheels will show as missing. The frequency of these alerts has caused me to ignore the TPMS system, rendering it ineffective. I have had it in for service on 5 separate occasions. The first time was Feb 2022, and the last time was 10/4/2022. During the service visits, additional antennas where added, antennas where relocated, and adjusted. This last service visit the dealership informed me that this is a wide known problem and they directed me to call Spartan Chassis. I called Spartan Chassis on 10/5/2022 and spoke with Dave. He took my vin and said it is a widely known problem and they will let me know when they have a fix. I asked how soon, and he said he has no information. I called Newmar Corp on 10/5/2022 and spoke with Mike. He referred me to Spartan, and said they would look into it. He too was aware of the many issues, but assumed they had been fixed. I called Spartanlync, the manufacturer the TPMS and left message without a response. The 2023 Newmar London Aire has a newer product delivered by Spartan & Spartanlync (companies not related) that resolves the issue, but I was denied getting this installed to resolve my problem.
