Driver's side seatbelt strap always wet when raining or washing.

Your car will need to be water tested to find out where the leak is coming from. Time will need to be taken to remove the interior trim from the affected area. Water can then be sprayed onto the exterior, the technician inside can then see exactly where the water is coming in. Depending on the mileage on your Honda once you know the exact cause of your water leak I would suggest you contact Honda customer service to see if they will help with the cost of the repairs. Unfortunately the musty smell may be difficult to get rid of. Once the leak is corrected and the interior is dried then spraying a disinfectant such as Lysol under the carpets may help with the smell.

Uniside trim needs to be removed. You need to seal along the uniside seam & roof. It's a mojaor issue with many Honda's not just the Odyssey!!! Honda should be made to recall as it poses threats to airbags & seatbelt functions!!!!
