What this page shows
Everything below is an owner-reported complaint submitted to NHTSA about the 2018 Tiffin Phaeton, grouped by the component NHTSA recorded on the report. These are not confirmed defects, and they are not recalls. NHTSA does not verify most reports before publishing them, and a category with more reports in it is not evidence that a part is defective.
Complaints are reports submitted by owners and drivers to NHTSA. They are not verified and do not establish that a defect exists.

I SAW A POST ON THE TIFFIN RV FORUM REGARDING THE VALVE STEM STABILIZERS THAT FREIGHTLINER PROVIDED ON RECENT RV CHASSIS EQUIPPED WITH A NEW STYLE RIM. I HAVE A 2018 TIFFIN COACH AND HAD THE SAME ISSUE SOON AFTER I PURCHASED IT. I NOTICED THAT THE VALVE STEM WAS RUBBING ON THE CHROME WHEEL AND IN FACT HAD RUBBED OFF THE CHROME DOWN TO BARE METAL. I TOOK IT TO BAY DIESEL IN RED BAY, AL. AND THEY REPLACE THE VALVE STEMS. THEY SHOWED ME ON ONE WHERE IT HAD ALMOST RUBBED THROUGH AND THERE WOULD HAVE BEEN AN AIR LEAK IF I HAD DRIVEN IT MANY MORE MILES. I WAS TOLD IT WAS NOT WARRANTABLE AND I PAID FOR THE REPLACEMENT STEMS. IT HAPPENED AGAIN SOON AFTER AND WHEN I CALLED FREIGHTLINER, THE PERSON I TALKED TO SAID THEY KNOW ABOUT THE PROBLEM BUT HAVE NOT COME UP WITH A CORRECTION AS YET. MFR BUILD DATE WAS 4/1/2018.

Tires & wheels
Reports naming tires, wheels, hubs, or the tire-pressure monitoring system.
From owner reports, verbatim
tire size 275/80/22.5 Driving down highway 301, driver side steer tire’s side wall blew out with no warning. My motor home made a hard left, luckily no one was in that fast lane. I managed to recover control and started to head to the shoulder of the road. Before I could reach the shoulder the rim cut the tire and threw it off the rim and into the highway. This put my life , my wife and anyone on the highway’s life in severe danger!!! I called michelin and their rep inspected the tire and felt the tire was run low. I completely disagree. All tires were checked that day and if this steer tire was low it would have pulled to the left!!

Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers.
