We bought a new RDX two months ago and now have been hit with a $4,500 bill to repair the roof’s “complete collapse.” We mounted a bike rack on the roof, virtually identical to the one Acura sells as an RDX accessory. My son got on the roof to make sure that the bikes were placed in the rack properly – just like we’ve done on other cars we’ve owned with bike racks. This turned out to be a giant mistake, even though Acura never states anywhere that you shouldn’t do this. This time though the weak, badly- designed Acura roof “collapsed.” Acura will not cover this huge expense – so much for customer service. My advice: don’t buy this car; especially if you’re putting something on the roof.
