Changed tires and now "Service Stabilitrak" message
I changed all four tires on my 2014 2LT RS about two weeks ago and when driving home from work tonight, the "Service Stabilitrak" message popped up. The light blinked for maybe 2-3 minutes and then went off. However, I noticed right away that the feel of the car was different. During both acceleration and braking, there was this slight pulsating - it only lasts for a split second every time I accelerate or brake. It's kind of hard to explain, almost feels like it skips a bit. Has anyone encountered this before? I'm assuming it has to do with the tires - either weren't balanced correctly or the alignment is off?
