I have a 2004 Acura Mdx. There are about 77,000 miles on it. Vsa, vtm-4, abs, and airbag lights keep flashing. So I took it to my Acura dealearship and they told me that after diagnostic that the rear differential failed. I believe there is something wrong with the wiring of all Mdx in or around 2004. There has been numerous repoertings of rear differential failures in 2003 and 2004 Mdxs. Acura should take a look into this and maybe do a recall. This is very dangerous because the transmission makes a loud noise and slows down when you are driving almost as if the transmission was about to go out.
