  1. Filed Jan 5, 2026Failure Oct 1, 2025Leeds, ALUnknown or other

    The instrument panel located on the dash is a digital display. There are cracks forming making the view difficult to see air in the tanks or speed. This is built on a Freightliner chassis. I have seen other RV forums where this is a common problem. This cracking will continue to get worse making it difficult to see any instruments on the panel.

    Built in TPMS system failing by year 3. Know Freightliner problem. Batteries also dead in TPMS by year 3. “Out of warranty”. Safety issue as tire related incidents one of the largest causes for accidents and death. Freightliner knows they have a bad system but refuses to provide customer service. Well known issue if you look at forums.

  3. Filed Apr 14, 2025Failure Apr 14, 2025Lady Lake, FLInstrument cluster/panel, Unknown or other

    The Freightliner optiview instrument cluster dash display delamination is starting. All the vital information in order to be able to operate my Rv safely on the road is a concern. From knowing my speed to all the vital engine and tire conditions is a road hazard. I would hate to cause an accident due to this serious flaw with this part. Freightliner claims they are not going to replace the dash under warranty. I believe that a safety recall is justified.

    The TPMS system has never worked consistently and is not reliable. Sometimes it will detect 2 or 3 wheels and sometimes only 1 or none. Freightliner should recall this Gen1 sensor as I've heard of this happening with numerous RV'ers

    This is reference to the recall for the TPMS system (tire pressure measurement system) under recall campaign SF644A-C. According to the freightliner people they have preformed the necessary recall work and have closed the recall notice as being complete. However, the TPMS still does not work. Now it shows a tire communication error. It is still the same system that is not working!!!
