I have a 2022 Max Stealth Performance, and it's vibrated 75 mph+ right from day 1. I've had more tire balances than I can count and three different sets of wheels and tires (two aftermarket winter tires/wheel sets and the stock 22" grabbers) with no improvement. The dealer just always says the usual. They can't test over the speed limit (which is 60mph all around the dealer) and they can't feel the issue.
It has CCD and does ride rough. I would call it "jittery" - like it's overdamped. The smallest road imperfection causes the vehicle to start jittering. I've been down freshly-paved highways that are butter smooth on every other vehicle, but mine's always jittering around.
