2026 Ford E-350 Chassis / Thor Four Winds 25Z motor coach; which only had about 800 miles on it! While driving north on I-81, the low tire pressure warning came on. So, I switched to the tire pressure screen and the outside left tire was dramatically loosing pressure from recommended 65 psi - dropping to around 30 psi within a few mile. We pulled of onto the shoulder, with only 3-4’ clearance of traffic. My wife and I found that the angled extension valve stem came unscrewed from straight connection on the rim and was loosing lots of air. I was able to hand tighten the angled extension, then with needle-nose pliers snug up the valve stem extension. I then was able to use a portable compressor to re-inflate the tire to spec and continue out trip. However, had we not recognized the dramatic tire pressure drop, I’m sure we would have had a blowout!
NHTSA complaint 11733842The vehicle I rented — a Thor RV based on a Ford E350 — was handed over with a missing lug nut on one wheel and a dangerously loose lug nut on the opposite rear wheel. The component that failed is part of the wheel fastener system (lugs/nuts/bolts). It is not available for inspection now, as the vehicle has since been returned to the rental company. This situation posed a serious safety risk — had the remaining nuts failed while driving, the wheel could have detached entirely, potentially leading to a crash or injury. I noticed the issue during a basic inspection many miles after the pickup. I was forced to buy and install a replacement lug nut myself to make the vehicle roadworthy and safe to drive. I have the propf that the vehicule was handed over to me with a missing lug nut as the video I took during tje check in shows the missing lug nut. The issue was confirmed independently by me, and I informed the rental company immediately. They acknowledged the problem and promised to refund the cost of the part. However, it has now been over two months, and they have neither issued the refund nor provided any follow-up. The vehicle was not inspected by police, manufacturer, or insurance, as I managed to resolve the issue myself to avoid driving in unsafe conditions. There were no warning lights or messages — only a physical inspection revealed the problem. I am filing this report because I believe the company rented out a mechanically unsafe vehicle, and others could be at risk if this is not addressed.
