Sometimes when I slow down from higher speeds, then go to accelerate, my 2011 TL hesitates for a split second as if the brake was applied. For example, this morning I was driving about 55mph, slowed down to about 15mph to make a turn, then went to accelerate again and it was like someone tapped the brake pedal causing me to lunge forward a bit, then the vehicle accelerated as normal. Anyone else experience this? I'm wondering if it's just a software issue or if it is TC related.
