Took my 2003 Mdx to orland park, IL Acura dealership for oil change and noise under vehicle. The service tech checked the noise and suggested the transmission need to be at $120,000. The vheicle has been properly cared for. As I read thru many blogs I see that Acura/Honda is totally aware of this issue however when I called Honda they would not offer any assistance other than $500 off for an issue that is known by Acura that is affecting every 2003 Mdx out there. Justice need to service and its time for Honda to be held accountable for this product they have out on the streets. This is unsafe and can cause death not only to Acura customers but customers from other vehicles.
I just bought a 2003 Acura Mdx with 110,000 miles. I drove the car less than 15 miles and noticed a scraping noise coming from the rear. A little further down the road the vehicle bucked and then the d5 light started flashing. There was hesitation in between the gears. The vehicle is now in the shop getting a new transmission - I had it less than 20 minutes before it started having problems.
