I purchased a CPO 2013 Model S85 in Feb of this year. Love the car, but the car seemed to have a wheel out of balance or something that caused the car to vibrate and shudder a bit at 80mph... 19 inch wheels switched out the brand new tires for winter tires, seemed better but still shuddered. Winter tires were on for about 4000 miles, had really uneven wear, then put the regular tires back on and had an alignment done, car still shudders, had wheels balanced again, no real improvement. finally got the car looked at today for the shudder, and squeaky suspension. Here is what i got in an email... "The technicians are working on your car. The car is need of all 4 wheels. They are significantly bent and a couple of them in more than one spot on the same wheel. The technician also noticed all 4 caliper pistons are seized and the sway bar link has excessive play." So somehow all four wheels bent? and "not covered" by warranty. they want $1600 to replace these crappy rims. I have had a multitude of cars over time, and have NEVER bent a wheel, much less all four. I’m not a stunt man, nor is this the General Lee, so i haven’t jumped any rivers! How do I escalate this?
