That's definitely not normal, and sounds like a recipe for disaster! You're basically asking for those handles to get ripped off by the brushes. It's probably a sensor glitch or some weird interaction with the car wash's water jets confusing the system. I'd definitely be pulling the manual and checking for any "car wash mode" or a setting to disable those handles, and if you can't find anything, I'd seriously consider hand washing it or finding a touchless wash. You don't want to risk damaging your car!
