We bought a new RDX two months ago and now have been hit with a $4,500 bill to repair the roofs 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 weve done on other cars weve owned with bike racks. This turned out to be a giant mistake, even though Acura never states anywhere that you shouldnt 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: dont buy this car; especially if youre putting something on the roof.
