Owner complaintsComplaints are reports submitted to NHTSA by owners and drivers. NHTSA does not verify most reports before publishing them, and a complaint does not establish that a defect exists. Volume is influenced by how many of a vehicle were sold, how long it has been on the road, and how much attention an issue has received.

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.

NHTSA ID 11678081 · filed Aug 3, 2025

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

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.
