Bulldog, I have had my TLX since October-4 cyl with tech. It surges to a stop about every 4 or 5 times. Big lag from time you step on accelerator to moving, and then it jerks between the early gears from a stop. I've been in touch with Acura Client Relations and they said there is a patch out that is supposed to fix this, but this is the third time I have heard this. I'm taking it in for the third time this Friday. Wish me luck! Very disappointing as this is my 5th Acura and it is junk!
