2014 Enclave - Purchased new tires, Goodyear Eagle, at 45,000 miles. Wife hit a curb at very slow speed so we had a frontend alignment checked and it was a little out. Tires were rotated and balanced. There was a vibration at highway speeds being felt in the pedal and steering. Took it in to the dealer again and they performed road force balancing on all tires...I was told that 3 of the tires had to be turned on the wheel to achieve the best balance. I am feeling some vibration in the passenger seat and floorboard and there is a very slight steering wheel vibration at highway speeds. The cost of these tests is at $290 so far. I am wondering if I am too critical...I think the Enclave should have a smooth ride.
