Notes: The 2005 Nissan Altima has two fairly significant problems with the floor pan rusting through & motor mounts breaking.

Altima owners report that up to a basketball-size hole develops under the floor mats where the floor pan metal rusts through. Average repair cost is over $1,000.

The broken motor mounts are less of a problem - they break at ~75,000 miles average & it's $400 to fix. Still, motor mounts should not break!

I started leasing my Altima in 2008 and purchased the car about 4 years later. I took it to have my muffler checked, because I heard noise, and it was found that the floorboard on the front, passenger side, is completely rusted out. The only thing between my passengers and the street is the carpet. Nissan said there is no recall. The car is only 11 years old!

My 2005 Nissan Altima has major rusting on the passenger side of the vehicle. This was found after the carpet on the inside of the car started falling through the floorboard. This issue almost had my wife's foot through the floor, without her knowing. This has been reported (via research and reports on the news) to both Nissan and NHTSA and both state it is not a safety issue. How is this not a safety issue if you don't know about it and you could put your foot through the floor?

The floorboards on my 2005 Nissan Altima are corroding and rusting out. You can touch the floor carper from the bottom! this is happening on both sides of the car the driver and passenger side. This is supposedly a known issue with this car make/model and this has happened to a lot of people. I am not sure but the repair costs are very expensive for this type of work.

Brought my 2005 Nissan Altima to mechanic for service. He noticed both driver side and passenger side floorboards rotted out. Each side has a 6" - 8" wide X ~18" long rectangular hole in the floorboard underneath the carpet. You are able to push up on the carpet from underneath the vehicle on both sides. The only thing separating the driver or passenger's feet from the road in these areas is the carpeting.

My Altima is well maintained car bought all new from Nissan dealership. State of Pennsylvania needs state inspection done every year and this year my Altima failed safety inspection. Meaning, my car is deemed not safe to drive on the street because of Nissan Altima's design flaw making floor-board behind front wheels go rusted. I use the car to commute everyday to work, unknowingly exposing myself to unforeseen danger. Nissan should have addressed this common issue happening to many other consumers before any life threatening incident occur to their so called "customers".

My 2005 Nissan Altima passenger side floorboard has rusted through. After speaking with a local welding shop I discovered that this is a "typical" issue with older Nissan's. they informed me they have seen this on about 6 Nissan's in my area. I feel even if a recall has not been called, I should have been informed somehow of the potential issue. There seems to be a design flaw as this is not just a rare occurrence. My vehicle has just under 107,000 miles and I am baffled how the other body areas show no signs of rust with the exception of one area of floorboard. I am not providing a photo as this has been reported nationally for some time now and it doesn't appear anything will be done about it. You can google "Nissan floorboard rust" if you need a visual.

Rust through of undercarriage under passenger and driver seats. Widely known problem that Nissan is aware of but refuses to issue a recall on. The rust occurs from the inside out due to inadequate drainage of water. Found out about it just today while getting an oil change.

I purchased a used 2005 Nissan Altima - only to find my passenger floor near the door is rotted/rusted out!! I do not have money to spend thousands to repair this. Why isn't there a recall? I have seen many many posts on the matter but unfortunately only after I bought the car!

We noticed something hanging down from under passenger side and found that both sides of the floorboard are comepletely rusted out with big holes in the floor!! we have a 2005 Nissan Altima. We called a body shop and they said it would cost over $2000 to fix. How is this not a recall and safety issue"? Nissan do you not care about your customers safety?" we were gonna buy another Nissan maybe a Nissan rogue but if this is how they(Nissan) take care of their owners then im not so sure!! step up Nissan and do the right thing!!!!!

I noticed something hanging down under the vehicle directly under the drivers side. I had a neighbor who is a mechanic look under the car. He told me that the under carriage floor board was completely rusted through and was so bad it would be dangerous to continue driving it. I can't afford the repair. What can I do?

Floor panels rusting completely through. Tire mechanic noted that "driver foot well has rusted through and carpet is visible on underside of vehicle". internet search strongly suggests that this is a design flaw in the water drainage system of Altima made during this time frame (as you are aware). Car runs beautifully otherwise, but I have to believe that having the carpet visible from underneath is a safety issue that should be addressed by Nissan.

The floor boards on both the driver side and passenger side have rotted out. We discovered this problem when my wife accidentally pushed her foot through the floor while driving 70 miles per hour on the highway. Fortunately she wasn't hurt. Judging by the extent of the rust, this has likely been an unknown issue since before I bought it 3 years ago. I would guess that it was significantly rusted well before 100K miles.
