My Nissan Altima VIN # included separately, has about 90,000 miles on it. It was bought February 2007 and has been owned by me since then (first and only owner). I performed my 90,000 mile servicing today and was notified by my mechanic that the floor boards on passenger side and driver side (undercarriage) are rusting and I can see a hole opening up there. He showed me while I was waiting for my car to get fixed at the shop. The rest of the undercarriage seemed fine. This indicates a manufacturing defect to me. I also would like to point out that this is a clear safety issue with the vehicle: Modern vehicles ought not to rot like so, and such a rot exposes the passenger and driver at great risk while operating the vehicle. I am getting extremely uncomfortable now operating this vehicle. It has served me well, and the engine/drivetrain has itself been trouble free. However, if the floor boards rot like this, I am unsure about the vehicle's overall structural integrity.

I took my car to get inspected and was told by my mechanic that both the drivers side and passenger side floor boards are rusting out. Because I know some people that can do the repair work for me I'm looking at about $1200 for the repair. Now that I've seen what some other people are being quoted I guess that price is fair. I already have exhaust coming through my floor and am concerned for my health at this point. Other then this issue my car is in perfect condition. My concern is if I don't fix this, my car in not safe.....so I do not want to drive it and I could not sell it to anyone in good consciousness because I would knowingly be putting someone else in harms way. Nissan needs to take care of this huge engineering flaw and safety hazard.

Driver and passenger front floor boards are rotted. Car is in excellent condition and has had all required maintenance completed since purchased new. Nissan North America Consumer Affairs refused to repair stating the car is out of warranty. Failure is due to manufacturing defect, improper rust protection of sheet metal, and water drainage issues.

Took my car for its yearly state inspection and it was rejected due to the fact that the floor had rusted through and now needs to go to a body shop to have the drivers floor replaced.

My 2006 Altima has been meticulously maintained, serviced and driven with no issues until recently while repairing a leaking radiator hose, I noticed that both the front passenger and drivers floor had a rusted thru hole in the same location, right where the feet would rest. No other part of the floor pan or undercarriage has any rust. I brought car to a body shop and as told this is a common problem with Altima in this year range. From what I have found in my research, Nissan is not addressing this issue.

Inspection on August 5, 2013 revealed rusted holes in 2006 Nissan Altima driver and passenger side floor boards. This is extremely unacceptable for a 7 year old vehicle. I have been a Nissan brand family since 1989 and have taken extra maintenance measures to get my vehicles past 200,000. After researching the web, many forums show Nissan is refusing to address this major common problem. I will consider repairing my vehicle and trading in to another manufacturer.

The vehicle has been very well maintained and I noticed today that the floorboards on both sides in the front are rusted right through. By searching the internet, I see that this seems to be a recurring issue for other consumers.

Found that the passenger side floorboard is rusting out on my wife's 2006 Nissan Altima. There was a musty smell buildup in her car. On inspection, found that the passenger side carpeting was damp. The floorboard had 2 large spots were it was starting to rust away. We have always kept the car washed and cleaned throughout our ownership of this vehicle. We are the original and sole owners of this vehicles.

This is about the 15th newer Altima that has no floorboard in it and I dont see how the cars will fare well in a crash. I decided to complain because of she sheer volume of people saying their cars are affected the same way. You have to do something about this !

- Indianapolis, IN, USA

Took my Nissan Altima to the dealership for some work. The service dept. Called to tell me there was an issue with the floorboards. And the car would pass inspection. I called Nissan and they said there is nothing they can do. I bought the car three years ago as a certified Nissan with a 100000 mile warranty. The car had about 35000 miles on it when I bought it.
