What 63 owners told NHTSA about the 2026 Ram Ram 1500 Crew Cab Rho

The auto leveling air suspension in my 2026 RAM 1500 does not operate as designed. The vehicle is designed to lower from normal ride height to aero ride height at speeds above 63mph. However, it is not supposed to raise or lower at any speed automatically with a trailer with an integrated trailer brake controller attached to it. In January 2026, I was merging onto the highway with my 7x16 enclosed trailer and the rear end of the truck because unstable the stability control activated and when I looked at the dash it stated aero ride height achieved. I have video of this happening more than once. I took it to the dealer on January 16th was told to bring my trailer in and they woulf perform a comparison test with a truck that is equally equipped. It took from January to June to perform the comparison test. Stellantis has confirmed they are aware of the issue but they do not have a solution for it at this time.

I was merging onto Interstate 20 with my 7x16 enclosed trailer properly hitched to my 2026 RAM 1500 with factory four corner air suspension. Upon reaching 63MPH the truck lowered from normal ride height to aerodynamic ride height. This caused a sudden and significant shift in ride stability and introduced sway that normally would not exist. The owners manual states that when in tow/haul mode and with a trailer connected to the truck with an integrated trailer brake controller module the truck will remain at normal ride height regardless of speed. Local dealership is clueless on remedy and this ride height shift continued throughout my towing experience that weekend. This is completely unsafe and will endanger not only the operator of trucks doing this but other drivers on the road. As it shifts the load of the trailer, increases hitch weight, and ultimately impacts the payload of the vehicle as well.
