2023 Chevrolet Equinox Wheels Problems

When flat towing behind a motorhome, per manual instructions, going on or off a highway ramp....cloverleaf, the tires will squeal like they are dragging. This does not occur every time, however 75% of the time it does. A very loud screeching, dragging or braking, pulling the motorhome down from 35mph or 40mph to 10mph. This is also noticed occasionally on turns from one street to another, however short lived by comparison. The dragging/slowing is unnerving and dangerous to suddenly slow down with no brake action by the motorhome. This has occurred on several trips this summer (2023). ****Several times this summer, most recent of 10/12/23. This car was purchased primarily because it states in the manual, it could be flat towed behind a motorhome. We are concerned that this may be damaging the vehicle and putting us and others at risk.
