Tire pressure monitoring system displays fault at random intervals while vehicle is in motion, primarily associated with the rear axle but affecting all six tires on the vehicle. Tires are not damaged and no indication of rapid deflation or other defect is present. Problem is intermittent but typically appears after approx. 20-35 miles of driving and lasts for random interval, after which problem self-corrects. The process repeats without warning. Vehicle has been inspected by multiple factory authorized service providers, chassis manufacturer blames problem on coach builder, coach builder is non-responsive despite multiple attempts to contact via phone. Vehicle has been in for service on this specific problem three times, no solution. Safety is at risk due to faulty information and lack of awareness of tire pressures on all wheels, also cannot disable system. Problem first occurred with less than 2000 miles on odometer, has been present intermittently since then. Tire sensors have been replaced, issue remains. Problem confirmed via photo evidence and acknowledged as a known issue by local Ford dealer service rep Brian on 3 July 2023. Additional details are for most recent iteration of problem.
