I just learned fron my dealer today that My ($62,000 sticker price) 2013 Platinum XTS with a little over 20,000 pampered miles has not 1.2.or 3 BUT all 4 20"rims should be discarded because they are bent. These rims LOOK perfect, no pits, stsins or marks. I reminded the dealer they HAVE DOCUMENTATION THAT i HAVE BEEN complaining about the ride quality and road noise, both since before 12,000 miles, but A L A S they don't seem to value a customer that has owned 3 previous Cadillac's. My Uncle and brother both want to but an XTS after seeing mine. I can't wait to tell then the dealer wants me to spend $2,900 and that's not all, they wany to scrap the Bridestones and quote "sell me a set of good Michelin's!!" ha! What a joke! They said there was nothing available GM abosulutly would NOT stand behind any warranty structal rims, tires or for any reason...WOW I am blown away by a dealer who has been terrific until today.....I guess GOODBYE Cadillac hello Lincoln, BUT, is Lincoln any better!!!
