WE WERE STOPPED AT A GAS STATION TO FILL UP..WE HAD STEPPED OUT OF THE MOTORHOME TO BEGIN FILLING...MY HUSBAND DECIDED WE NEEDED TO PULL FORWARD...WHEN I ATTEMPTED TO ENTER THE MOTORHOME...THE DOOR WOULD NOT OPEN. FORTUNATELY, WE, SENIOR CITIZENS, CLIMBED THROUGH AN UNLOCKED WINDOW NEAR THE DRIVERS SEAT AND WITH THE HELP OF A KIND PERSON ON THE OUTSIDE, WE WERE ABLE TO OPEN THE DOOR AFTER ABOUT AN HOUR OF WORKING ON IT. THE ENTRY DOOR LOCKSET FAILED LOCKING US OUR OF OUR MOTORHOME. THE PLUNGER WAS MADE OF POT METAL AND FAILED/BROKE IN HALF, CAUSING THE PIECE IN THE DOOR STRIKER PLATE TO REMAIN STUCK IN THE CLOSED POSITION...CAUSING THE DOOR TO BE CLOSED IN A LOCKED POSITION. TRIMARK/DEXTER LOCKSET FOR RV #29412 38H THOR AND TRIMARK ARE AWARE OF THIS ISSUE ..TRIMARK HAS MADE A STEEL PLUNGER TO 'FIX' ISSUE BUT MAKES NO EFFORT TO ALLEVIATE THE COST OF REPLACEMENT...THOR IGNORES THE ISSUE.

I HAVE COMPLIED WITH SAFETY RECALL 15V-530, SAFETY ADVISORY RC000103. THE PROBLEM REMAINS, NO CHANGE, I CANNOT DEFROST THE WINDSHIELD. THE ONLY SIGNIFICANT AIR FLOW IS TO THE FLOOR REGARDLESS OF THE AIR FLOW CONTROL SETTING. AS STATED IN THE RECALL, THE VEHICLE WAS EQUIPPED WITH A DEFECTIVE AIR FLOW CONTROL UNIT WHICH DOES NOT PERMIT AIR FLOW TO THE WINDSHIELD DEFROSTER VENTS. TMC'S "FIX" IS TO PREVENT THE SPIKE WHICH DISABLES THE DEFECTIVE CONTROL UNIT, HOWEVER, THE DEFECTIVE UNIT REMAINS. IN MY CASE, THE UNIT IS ALREADY LOCKED AND I CANNOT DEFROST THE WINDSHIELD. THE RECALL SHOULD INCLUDE REPLACING THE DEFECTIVE PART. THE CURRENT REMEDY HAS NO IMPACT ON VEHICLES WHOSE DEFECTIVE AIR FLOW UNIT IS ALREADY LOCKED. THE CURRENT REMEDY LEAVES THE DEFECTIVE UNIT IN THE VEHICLE AND IN MY CASE DOES NOT REMEDY THE SITUATION BY WHICH THE RECALL WAS ISSUED FOR.

Thor Motor Coach (Thor) is recalling various 2003-2018 recreational vehicles, equipped with Kidde Plastic-Handle or Push Button 'Pindicator' Fire Extinguishers. See a list of the affected trailer models at: https://static.nhtsa.gov/odi/rcl/2017/RMISC-17V758-5764.pdf. These extinguishers may become clogged, preventing the extinguisher from discharging as expected or excessive force may be needed to activate the extinguisher. Additionally, in certain models, the nozzle may detach from the valve assembly with enough force that it could cause injury and also render the product inoperable. For a full list of the affected fire extinguisher models visit: https://static.nhtsa.gov/odi/rcl/2017/RMISC-17E062-5427.pdf
Consequence & remedy
Consequence: In the event of a fire, if the fire extinguisher does not function properly, it can increase the risk of injury.
Remedy: Thor will notify owners, instructing them to contact Kidde for a replacement fire extinguisher, free of charge. The recall began on January 15, 2018. Owners may contact Thor customer service at 1-877-500-1020, or Kidde customer service toll-free at 1-855-262-3540, or online at www.kidde.com and click on "Product Safety Recall" for more information.
Thor Motor Coach (TMC) is recalling certain model year 2016 Axis and Vegas recreational vehicles manufactured March 26, 2015, to July 6, 2015. In the affected vehicles, the heating, ventilation and air conditioning control may lock on one setting, preventing the operator from changing the air flow, thereby eliminating the ability to defrost the windshield.
Consequence & remedy
Consequence: If the windshield cannot be defrosted, the driver's visibility may be affected, increasing the risk of a crash.
Remedy: TMC has notified owners, and dealers will install a jumper harness to prevent the condition, free of charge. The recall began on September 1, 2015. Owners may contact TMC customer service at 1-877-500-1020. TMC's number for this recall is RC000103.

PE20021 · Trimark 060-1650 Door Latch Failures
Opened Nov 23, 2020 · Closed Dec 13, 2024
Status: closed (inferred from source dates) · Equipment
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 Owner’s 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 and pets. ODI analyzed the data provided by Trimark in response to its January 27, 2021 information request letter.Although an elevated failure rate was evident on a specific combination of plunger bolt, door lock/latch assembly and door, the data showed that most failures occurred within the first two years of service on the affected 2015-2017 vehicles.This data suggests that component failures generally would have already occurred.Further, ODI data reflects a downward trend in complaints after calendar year 2018 and for post- MY 2016 vehicles.This downward trend may be attributed Trimark's actions in 2016 such as changes in the manufacturing process of its zinc plunger component for the relevant population and its 2016 decision to switch to a steel plunger. In view of the nature of early-life failure, and failure rate trending downward for model years 2017 and newer, this Preliminary Evaluation (PE) is closed. The closing of this investigation does not constitute a finding by NHTSA that a safety-related defect does not exist.The Agency reserves the right to take additional action if warranted by future circumstances.
