I'm on my 4th MDX with the current one a 2015 model. I had a 2014 MDX that would fill all the front and back floors with water. The 2014 was not repairable and was replaced by my Acura dealer! They put us into a 2015. Well, it's happening Again!! My 2015 is back at Acura who has removed the interior and sent it to their body shop to repair seams that weren't properly sealed. Per our discussion with them today, the problem is much worse then originally thought. I'm very happy that this vehicle is leased! Unfortunately if they can't fix this one I do not want another MDX, especially the new 2017 one with the button transmission. Apparently the transmission has been a nightmare for Acura. Has anyone else experience the water issue? If so, what was the cause?
