I have a 2004 Acura Mdx. Before christmas this year I had the timing belt and water pump replaced . WE had heavy rains for a few days and I noticed a musty smell and the carpets were soaked along the front edges of both the driver and passenger side. Took it back to the dealership and they said to take it to a collison repair and have them dry it out and then check for leaks. They also asked if we had windshield replaced recently - no we havent - any one else have ideas - I read forum on 2002 that talked about seams under fender wells ???

This is likely the infamous MDX leak that is a result of poor manufacturing quality. There is a place where the inner fenderwell (same as the inside front footwell) meets the A-pillar sheetmetal frame (this A pillar sits behind engine, holds windshiels..etc). The sealant used where these two sheetmetal panels are welded was not applied sufficiently in many cases and it dries and falls out
after a few years. Worse yet - there is a 'pocket' formed where the sealant goes bad that can collect water in heavy rains. The result can be a trickle of water through the seams and into the carpet of the driver / passenger side footwells. Our MDX (Many Defective eXchanges) became a soggy mess last winter with the heavy rains in California. After much research on ' mdxers.org '- I
found out that this problem was common. After listening to owners
description on what the dealer or customer finallly did to fix this - I took what I learned and headed down to a body shop and instrcucted them in what to do to dissasemble, seal, and reassemble my MDX to fix this.$400 later - done! no more problem! Dealers will not acknowedge the issue and will charge $$$$$$ to diagnose and supposedly fix problem. Tracy at Los Gatos Acura is a good guy that can diagnose and fix this - but he is an Acura Dealership body shop - so a bit pricey - although he takes care of all my fender benders and is very good. I just opted to go a lower cost route as I new what was wrong and what needed to be done.

I live in San Jose as well. Where did you end up taking the Acura to have it fixed?

I have the same problem (seam sealer issue) causing wet floor mats. $1280 to fix, but I don't want the expense of a new car, so I have. Agreed to suck it up. My MDX is a 2004 with 126,000 miles. I sure hope I can get 200,000 miles out of it.

I have a small Body Shop in the Northwest. Customer had this problem with his MDX and Dealer could not fix it after replacing windshield twice. We ended up taking the front sheet metal off but found it was in the factory seam seals at the front footwell to firewall areas. Once a shop knows where to look they can fix it by lifting the car, removing the front wheels and the front fender slash shields. From there the seams can be resealed and undercoated. This can be done without removing the front outer sheet metal and without a huge investment; maybe 4 hours of work which here would be around $200, but probably twice that much in the cities with higher hourly body shop rates.
