The contact stated while driving at 50 mph, the contact’s husband saw smoke and flames coming from underneath the front driver’s side undercarriage. The driver pulled the vehicle over to the side of the roadway and exited the vehicle and saw a fire underneath the undercarriage of the vehicle.

You have a Technical Service Bulletin 20-2370 issued 09 November 2020 for this vehicle, so no notice to consumers until the issue arises and their mechanic figures it out. The issue causes an extreme heat build up that melts spark plug wires, causes loss of power and/or misfiring, and could cause a vehicle fire which is not noted in your bulletin. This should have been a recall ceasing sales until affected Ford F-53s were repaired. I encountered this issue while on 38 in the San Bernardino National Forest. This was a major safety issue with the loss of power on mountain roads and potential for fire, which would likely have sparked a wildfire. I also have a 22yr old disabled son who does not ambulate quickly so the thought of trying to get him out in the event of a fire is troubling. To your questions below, there could have been a crash, fire, and/or injuries. Is that what it takes to do the right thing? I’ll provide invoices when my mechanic is done fixing it.

While driving on the highway at 60 MPH in a thunderstorm, the passenger windshield wiper collided with the driver's windshield wiper and became entangled with each other. I completely lost all wiper function and could no longer see the road. This was a life-threatening situation, with traffic all around us, and luckily, I was able to pull off the highway after about a quarter of a mile until the rain subsided. My wife and two grandchildren were in the RV at the time and this could have been a disaster. I called Thor this morning and they are tight-lipped about this problem happening to others, but I see in online Thor forums that even after an earlier recall, it is still happening to more recent models like mine. In my case, the splines on the passenger wiper arm are totally stripped, as are the spices on the wiper arm pivot shaft. The driver's wiper was OK after taking it off and re-aligning it, but may not hold since those splines were also partially stripped. Thor needs to take responsibility for putting in such an unreliable wiper system which is manufactured by Wexco Industries. I'm now stuck with $500 in parts (more if the driver's side also needs replacement), not including labor, to "fix" their poorly designed wiper system, not to mention the near disaster we experienced.
