Ok, problem found!!! So it turns out one of the back tires has gone bad and it was just weird timing that it to happen when the front tires were replaced. What sucks is that the back tires still had plenty of tread on them but because its an AWD the tire shop said not to just replace that bad one. They said Michelin would give a credit for the bad tire but not the other. I guess Michelin in one of the hardest companies to deal with when this sort of thing happens. What I also learned was Michelin Diamaris are only rated for 20,000 miles -
