I recently had my car serviced and was told my floor panel had rotted through. The car is a 2004 but has less than 44,000 miles, has been serviced regularly and has been garaged part of the time.articles on the internet show it is a massive problem with these cars due to poor drainage design. The repair is over $2000. Otherwise the car is in good shape. This is just one of 1000's of reports to the NHTSA about this problem.

The passenger floorboard has rusted out leaving a 12" X 10" hole right in the area that you would step into the car. Since this is the area that is regularly inspected due to the location of the oil filter, hard to believe that this wasn't detected previously to just falling out.

Floor boards under the driver & passenger seats completely rusted out. Can see & feel the carpet from underneath the car. If you step too hard on the floor from the inside, you foot would go through and you would touch the ground.

Rust on floorboard requiring replacement of floorboard. Minor rust was observed via inspection when underneath the car; however, once the seat was removed, the shop indicated the problem was much worse, because the rust is occurring from the inside. This is not typical rust due to salt, etc.

During an annual inspection, it was discovered that both driver and passenger floor pans are rusting thru. Please note that this is a garage kept car with low miles for it's age. There is no other rust on the undercarriage of the car except in these areas. The inspector noted that this is not normal for a car of this age and mileage. After research on the ODI site, I've found numerous complaints for the exact same issue. This is a serious safety and structural issue that is known by Nissan for years, but they refuse to act upon it. The vehicle can now be considered unsafe to drive by fault of design of the manufacture. Please have an investigator open a ticket to have a recall, or at the very least, a manufacture fix since this is a safety issue...even though Nissan is stating that it isn't and they won't act...this should be a negligence case on the part of Nissan.

I own 2004 Nissan Altima 2.5S. I found a huge rusted hole on the passenger/right side floor pan/floorboard. My wife felt very unsafe while driving and I'm worried about the hole is getting bigger which can cause a possible accident. A local mechanic mentioned that he saw a couple of cars with the same issue and it estimated at least $1,500 to fix and figure out the reason of water leaking. I think Nissan has to recall the cars.

- Ames, IA, USA

There is severe rust/rot visible on at least the driver side floor board. I am the second owner of this vehicle which I purchased from a close family member and the car was well maintained. I am deeply concerned that this is a serious safety issue and why this was not detected during a recent nys dmv inspection. After doing some online research I learned that many other owners have experienced the same issue and I cannot believe that Nissan will not stand behind this issue. This is clearly a design deficiency/defect... severe rot should not occur in just 10 years. I purchased this car nearly two years ago and this repair will not likely be cost effective.

I noticed one day something hanging from under my driver side under body. Upon further investigation I notice the driver side and passenger side under body to be corroded out with about a 5 X 11 hole. I believe this to be a safety issue and think Nissan should be sending out a recall for this issue.

- Fairfield, OH, USA

I have two safety related issues with this vehicle. 1) the front subframe has holes due to rust. 2) the front passenger floor board is rusted through with a hole approximately 10" X 20". I took that car to fred martin Nissan for an inspection. They stated that these issues are not covered by warranty, recall or goodwill campaign. These issues appear to be manufacturing defects.

- Uniontown, OH, USA

Door handle broke off as I was trying to enter vehicle. About a year later, another broke off. There is sharp plastic where it was broken and it is very difficult to enter the vehicle, especially without cutting yourself. There are times when it is necessary to be able to enter the vehicle quickly and it is impossible. It is not safe.
