The vehicle was delivered from the factory with a severe size mismatch between its primary rolling stock and its emergency spare tire. The truck features factory-installed 20-inch wheels and tires but was manufactured and shipped with an undersized 18-inch spare tire assembly secured underneath the bed. On a heavy-duty 3500-series truck built for heavy towing and hauling, utilizing a drastically different tire diameter during an emergency road event forces the rear differential and transfer case to spin at mismatched speeds. This creates an immediate risk of sudden mechanical drivetrain failure, loss of vehicle control, or compromised braking stability while operating under load on public hi

Have been driving it on four separate occasions and the engine will start running rough and shut off leaving me with no power brakes or power steering.
