Since I've owned my 2012 Pilot EXL 4WD, it has exhibited a shudder when starting from a dead stop and making a turn which I believe I have fixed.
I was able to almost completely eliminate this problem after multiple drain and refills of the Honda ATF with Valvoline Max Life full synthetic ATF. I say "almost" since the fifth D&R seemed to eliminate the problem but it would creep back over time, like within a few thousand miles.
This fix never really convinced me it was the final answer since the shudder only happened in a turn from a dead stop, never on a straight away. And it never happened on any turn that wasn't made from a dead stop.
I think I found the answer, or at least one that makes some sense to me, in that if I turn off the traction control, the car no longer shudders in turns from a dead stop, or at any other time.
And as a bonus, the car accelerates faster from a stop, both in turns and straightaways.
Maybe there's something not to spec with my ABS or wheel speed sensors, but I'm not getting any codes on either system, ABS is working fine, and at this point I don't think it's worth pursuing any further. Although I'd like to find a way to turn off traction control permanently (leaving the ABS on), so I don't have to manually turn it off after each engine start.
