“Noise coming from 2009 Acura tax rearend driverside. Piping noise can be heard when stopping and accelerating. There is a frame flaw. I am told Acura has a design flaw. They have to fuse two metal pieces to get the noise to quit and the dealer had to order a special tool from torance ca. What else is wrong with this horrible honda product. Oh yeah and the engine pings a lot. What are we to do?”
