NHTSA Complaint #11448577 — 2020 TIFFIN ALLEGRO RED

This is in reference to NHTSA #21V-921. We received a recall letter from Daimler Trucks indicating that an inner rear tire support grommet and valve extension needs to be removed due to the possibility that the support grommet will fall out resulting in the potential failure of the inner tire valve extension. Daimler issued a similar recall in 2020 which was related to the same issue but the remedy was to replace and or reinstall the grommet. In our case a service center installed the grommet and used RTV to hold it in place. The recall states that if the grommet is not removed the Owner takes on the liability for a failure. The issue with the removal of the extension and grommet make it impossible to use a cap based tire monitor sensor since the chassis was not equipped with internal tire sensors. This creates another safety issue in that the inner tires cannot be monitored. Daimler has not provided an option to have internal sensors installed along with a means to monitor the pressure.
