Sounds to me like a dealership problem. I do wonder how he managed to bend four rims so quickly.
On top of that they'd have to be really out of round as I had an out of round rim on my Cruze and Discount Tire was able to balance it properly anyway.The likelihood that this guy got 4 defective rims seems...suspect. To me, this clearly seems to be someone with an agenda. He's glomming together issues allegedly from his own experience with every other possible bad experience he's heard of.
