What this page shows
Everything below is an owner-reported complaint submitted to NHTSA about the 2018 Thor Motor Coach Miramar, 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.

EVERY TIME I DRIVE THE RV AND A CHANGE IN TEMPERATURE AND HUMIDITY OCCURS THE WINDSHIELD AND BOTH SIDE WINDOWS FOG VERY BAD, THEY WILL NOT DEFROST AND YOU CANNOT SEE WHILE DRIVING DOWN THE ROAD, YOU CANNOT SEE THROUGH THE MIRRORS ON EITHER SIDE BECAUSE OF THIS, IT DOES NOT MATTER WHAT ROAD YOU ARE ON. NOT ENOUGH AIRFLOW FROM THE DEFROSTER AND NOT ENOUGH VENTS ON THE FRONT WINDSHIELD, IT HAS NO SIDE VENTS AT ALL. I HAVE REPORTED TO THE MANUFACTURE BEFORE AND THEY SAY IT MEETS THE INDUSTRY STANDARDS. *TR
