AutoNation Chevrolet North Corpus Christi

I was out of town so I sent my fiancé to get my tires rotated and balanced because a shake in the truck, but was mainly there to get the back part of my seat put back on. They repaired my seat in February on account of the recline not working and not to long ago I noticed the back plastic part of the seat was never properly attached when seat was replaced. I noticed this late because I never really sit in the back. The truck had a bad shake so I asked her to see about getting tires rotated and balanced. After all was said and done she called and said the truck still continued to shake. I got back into town later that week and noticed the tires were never rotated. I know this because I had two different brand tires, I asked the service desk if that would be a problem being there two different brands, therefore two different tread types yet the same size. He informed me it wouldn't be a problem. After seeing that I made sure the balance was even done. The stick on weights looked new and weren't the same weight that I previously had on the tires. I asked service why the tires weren't rotated and was told "all we do is balance, you don't always have to rotate." Any knowledgeable service department will know that when you balance, you rotate. You wouldn't change the oil and leave the oil filter. Was charged 59.99 for the balance which I was told included rotation [obviously not] and no charge for repairs to my seat because it was under warranty. What really sent me over the edge was when I took it to the tire tech's I work with [ I do not work in tire's we have a service dept. with our construction company. We can not do personal vehicles] said they couldn't believe someone would balance a tire this bad. I stood with them and looked it over, they showed me tread separation, high spots, and pieces of rubber chipping off the tire. I believe any tire tech, or person with some knowledge about tires should have seen how bad a shape these two tires were in. No one at AutoNation spoke with me or my fiancé about the condition of the tires. It was a quick here you go, pay your bill and next. As of right now the truck is not road worthy until new tires are purchased, so for safety sake and to save a world of questions I would not recommend AutoNation Service technicians that worked on my vehicle.
