2020 Tiffin Allegro Red

The contact owns a 2020 Tiffin Allegro Red attached to a 2020 Freightliner XC-M. The contact initially received notification of NHTSA Campaign Number: 21V921000 (Tires). The vehicle was taken to an RV dealer to be serviced under recall. Upon return of the motorhome, the contact discovered that the valve stem located on both the rear driver’s and passenger’s tires could not be accessed. The contact noted that the failure could lead to a failure since both rear tires could no longer be checked or inflated to monitor the tire pressure as needed. The manufacturer was notified about the issue and informed the contact that the recall repair was performed correctly; and offered no further assistance. The vehicle was not repaired. The contact had not experienced the failure. Parts distribution disconnect.

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.
