I recently got a 2015 C-Max Hybrid with a bit over 14,000. I soon noticed an intermittent pull to the right. I drive the same route to/from work, so I have a feel for the road grade.
At first I only noticed the pull (always to the right) during low speed braking. I'm still not sure 100% sure if it's only during regenerative braking. When it pulls, the steering wheel can move as much as 10 - 20 degrees!
Then I also started to notice that if I'm coasting (at any speed) and go over a bump I'll frequently get a small pull. I have not yet noticed it pulling during acceleration.
I took the car to the dealer for a Check Engine Light and asked them to look at it. Their response was that hybrid braking causes a pull. That doesn't sound right to me.
So, does your call pull during regenerative braking? If so, how much?
