Beginning in 2006 I started to experience a hesitation and a hissing sound in my 2005 Acura Mdx at hwy and local rd speed for the past three years I have taken the vehicle to the dealership only to get the same response of unable to duplicate. I recently took the vehicle to the dealership again on 11/09 and this time they were able to duplicate the problem which was a bad torque converter which required the replacement of the transmission. The dealer claimed the issue started at 58,000 mile and therefore out of warranty. The dealer wants $4000. 00 to replace transmission. Still contemplating offer. I have discovered blogs that states an ongoing torque converter and transmission problem with the Acura Mdx from 2001--2005 including a recall for 2001-2002.
