Rear end pulsating on 40-50 mph turns

[xjaywalker]

Hey guys.....OK this is weird. Two weeks ago I was exiting the freeway on a long right sweeping curved offramp and all of a sudden it felt like the brakes pulsated twice. Once the car slowed done and I straightened out it went away. I thought it was maybe something to do with the road condition and ignored it. Then it happened again last week and I thought I better get it looked at. Then it happened again today. Now I am concerned.

Things to note: My G has rear active steering and 43,000 miles on her and I just replaced the rear tires. Hankook EVO, 245/40/19's. As usual the tires wear out fast in the middle tread area.

Anybody ever hear of this happening.

Correction: This car does NOT have rear active steering (RAS).
