I bought a Subaru Forester so I could feel safe in the weather, but this car has been sliding me around all season. The tires claim to be all season but they clearly are not. I spoke with the sales department and they informed me that the tires are not their responsibility. This is very sad that they will not take responsibility for the products that they sell. I was told I would have to go with snow tires in order to get the protection I wanted. My last Forester drove excellent for 10 hard snow seasons on real all season tires. I was forced to go to discount tires and have new all season tires put. These new tires perform perfectly and this means the old tires were either bad or maybe all Bridgestone Ecopia tires are bad. I'll never know since the dealership did not want to help me with this problem. I feel like I've been ripped off to tune of $750 dollars since I bought a car that I assumed would have good all weather tires on but it did not and Autonation would not stand up to the warranty.
