I am reporting a serious and repeated safety defect involving Hehr side windows installed on my 2018 Thor Palazzo 36.1 motorhome (VIN: [XXX] ). Multiple operable side windows on this RV have experienced adhesive bond failure between the scissor arm/operator mechanism and the vent glass pane. This has caused windows to partially detach and violently flap while driving at highway speeds. One rear bathroom window completely detached and flew off the RV during highway travel in 2022. Additional adhesive failures have continued occurring from 2023 through 2025 involving: - Kitchen window - Living room window - Dinette window - Rear bathroom window (including replacement assembly) In several…

AS I was driving mr rv. down the road , the rear side window just fell off onto the roadway. I believe the window is made by lippert. On the rv forum there are a lot of people experiencing this same problem.

The contact owns a 2017 Thor Motor Coach Palazzo RV. The contact stated while operating the vehicle, the rear marker light, and the driver side(left turn) signal were inoperable. The vehicle was taken to the local dealer to be serviced under the NHTSA Campaign Number: 21V00H000 (Electrical System, Exterior Lighting) which would address the failures but after the recall remedy was performed the failure persisted. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was 26,000.

WHILE STATIONARY, FIRST LARGE WINDOW BEHIND DRIVER'S SIDE BROKE OFF, AT THE TOP HINGE, FOR NO REASON. IF THIS HAD HAPPENED WHILE DRIVING, IT COULD HAVE CAUSED SERIOUS HARM TO FELLOW MOTORISTS. AT THE TIME THIS HAPPENED, I WAS UNAWARE OF THIS WEBSITE AND THE ABILITY TO REPORT.*DT

WHEN PARKED IN A PARKING LOT AFTER A 1HR DRIVE, THE ONLY EXIT DOOR THE VEHICLE HAS DID NOT OPEN, PREVENTING US FROM EXITING THE VEHICLE. OTHER CAMPERS PARKED IN THE SAME LOT WERE UNABLE TO OPEN THE DOOR FORM THE OUTSIDE BUT ABLE TO HAND ME TOOLS TO TAKE THE LOCK APART FROM THE INSIDE AND OPEN THE DOOR USING PLIERS AND A SCREW DRIVER. THE DOOR LATCH MADE OF A ZINC OR SIMILAR DIE CASTING HAND BROKEN IN HALF PREVENTING THE RETRACTION OF THE LATCH AND KEEPING THE DOOR LATCHED.

WHILE DRIVING THE RV, THE WINDOW ABOVE THE SINK SEPARATED. THE WINDOW IS DOUBLE PANED. THE OUTER GLASS PULLED AWAY AND WAS FLAPPING, CAUSING THE INTERIOR GLASS TO ALSO START PULLING AWAY. WE WERE ON A STRETCH OF HIGHWAY THAT WAS BUSY WITH TRUCKS, APPROX 6:30PM (DARK), 2 LANES EASTBOUND I-40 IN CALIFORNIA. THERE WERE NO EXITS FOR 20-25 MILES AFTER THE INCIDENT BEGAN. THE WINDOW CONTINUED TO BANG AND PULL AWAY THE ENTIRE DRIVE. THE PULL FROM THE WIND THREATENED TO COMPLETELY SEPARATE THE WINDOW ASSEMBLY FROM THE RV. THE HIGHWAY SHOULDER WAS NARROW WITH A DROP OFF SO WE DID NOT PULL OVER AS THIS WOULD ALSO NOT BE A SAFE SOLUTION.

On November 23, 2020, the Office of Defects Investigation (ODI) opened PE20021 to investigate allegations of inoperative Trimark THP 060-1650 door lock/latches originally equipped on model years (MY) 2015-2017 Class A and Class C motorhomes.ODI received forty-six Vehicle Ownerâs Questionnaires (VOQs) describing consumers being locked in or out of their vehicles.The door latch, containing a die-cast zinc plunger, was produced by Equality during calendar years 2014-2016. The die-cast may become porous and brittle over time and can break without warning, causing the vehicle owner to be unable to open the recreational vehicle door equipped with the latch.If the motorhome does not have any other doors such as some Class A models, occupants could be trapped inside, needing to climb out using the emergency exits. If locked out, owners would be unable to easily get in and retrieve children…
