ScottyP: the cross bar pictured has been torqued & now uneven for reason you described. this has happened to me a few times when one side is unlocked, the other locked under load, twisting the tube. to correct depends on how bad it is. i made some adjustments & was able to correct the problem. Dealer gave me a quote of 1k to cut & replace the tube.
sounds like it happened @ dealership or factory, so it needs to be addressed @ dealership under warranty. if it is corrected w/o replacement, be aware the tube is slightly weakened & prone to the same problem again if one attachment lever is not locked down under load.
suggest securing both levers w/bungee cord once locked down,
another fix would be to cut the tube, reposition on level surface, & weld up. Personally, i'd let a professional welder do it. best of luck
