I have rust holes in the floor panel of my 2005 Altima. It will not pass inspection and while driving the hole is big enough that I can feel it under my foot through the carpet. I talked to my mechanic about a fix and he said he has done about 8-10 of these cars for the exact same problem. Looking online, this is a common flaw that many Altima owners have and it is an incredible safety concern. There should be a class action suit against Nissan based on the responses they are giving people who are asking them for help with the repair.

Went to get an oil changed and when completed the technician told me there was corrosion and rust in the floor under the passenger and driver side of the vehicle. After inspecting it, the floor board seems to be completely rotted/rusted through and you can see the inside of the car. He told me that it's wear and tear and maybe an autobody shop can fix it or I should trade in as soon as possible. This seems to be a design flaw and a very big safety issue. This is a body defect that needs to be addressed. Why doesn't Nissan realize this is not just one case.

I just noticed that floorboard are extremely rusted and rotted. I probably not noticed and this has happened long time ago since rust is that deep. Need help.

Went to get an oil change today for car and when the car was on the lift I had noticed some discoloring in the floor under the passenger and driver side of the vehicle. After inspecting it, the floor board seems to be completely rotted/rusted through and you can see the inside of the car. This seems to be a very big safety issue. Exhaust fumes can enter the car while in park or stopped. A foot can go through the floor and cause a very dangerous situation. This is a body defect that needs to be addressed.

Car was bought in Utah and used in Utah and Colorado mainly. The driver side floor pan is rusted through and needs fixing / replacement. This is a structural safety issue. Car is less than 10yrs old and shouldn't show this issue this early.

Nissan is garage kept with no rust on vehicle. Muffler on since 2006 and floorboards completely rusted through - muffler still good. Contacted Nissan Consumer Affairs and they would not cover. Paid dealer $1755 to repair since cheaper than new car and will drive until wheels fall off. Since no injuries yet, is this the reason nothing is being done. Seems to be many complaints on Altima from 2003-2006. Check out youtube - www.youtube.com/watch?V=hi7F1efhb00.

2005 Nissan Altima floor boards have rusted through which can lead to exhaust fumes entering the car, a safety issue. The floor panels should not rust completely through in 9 years. While living in new england does expose the car to salt, I would go through the car wash on a regular basis. During a routine oil change, I was informed the car would not pass inspection and that there were holes in the floorboard. I took photos documenting the issue. The rest of the undercarriage is in good shape but the area under the floor boards is completely bowed out and eaten through. This is shoddy materials and (lack of) craftmanship. I have seen many other similar issues posted to the database and wanted to lodge a complaint as part of my claim to Nissan. I have also replaced the oil pan which is also quite prone to rusting quickly.

Rust holes in driver and passenger floor boards due to design flaw.

- Ballston Spa, NY, USA

During my ri state inspection today, I was notified that my driver side floor board was completed rotted through. My car will not pass inspection without fixing that. The car is only 8 years old so having that much rot is very unusual. Will Nissan repair this damage or reimburse me for the cost of repair?

Both the drivers side and passenger side floor pans have rotted through.

Floorboards on Nissan completely rusted from outside in. Carpeting inside of car still looks like new. Numerous complaints on vehicles of this year, but Nissan consumer complaints will not cover cost of repair. Purchased the car new in May 2006 - was 2005 model. Summer 2009 put a bike hitch on car and muffler bolts were rusted but underside of car still looked great. Muffler still on the car, but floorboards completely rusted through. Almost $2000 to repair. Car was never in accident, never in flood and always cleaned and maintained. I found a piece, almost a sheet of rust on the floor of my garage. Undercoating on the piece was still there, but rust couldn't hold it together any longer. When pointed out what this actually was shocked. Feet on the pavement when driving was the next step.

I have a 2005 Altima with 49500 miles. When I recently got new tires, it was discovered that the front passenger seat floorboard was completely rusted. This is a safety issue, whether its fumes getting into the car or debris from the floorboard falling in the road. I contacted Nissan national and they sent me to a Nissan dealership to get an estimate and have it sent to Nissan national. Nissan national said my issue would go to Nissan consumer review, who decided the floorboard rusting out was environmental. Are car owners in wintry states forewarned that if they have a Nissan the floorboards might rust out? my car is clean with no other rust.

Noticed floor pan on passenger side of my 2005 Altima has rusted out. The hole is clean through to the inside of car. Approximate 8" hole.

- Cynthiana, KY, USA

Brought my vehicle in for state inspection to local Nissan dealership and was told the floor boards were too soft to pass inspection. Inspected the vehicle more closely myself and noticed the floor boards had been rotting. The vehicle only has 85K on it. Heard this is a major problems with a lot of Nissan Altima and felt I should report this since Nissan has done little or nothing to fix the problem which is a major safety hazard since I'm not one of the flintstones.

The wheel well liner on the front passenger side came loose and after flapping against the tire, road, and engine compartment; became totally disconnected and fell onto a county highway. It was replaced by a Nissan dealership's mechanics, and three months later the same thing happened on a city street!

- Vacaville, CA, USA

Owner of 2005 Nissan Altima. Two weeks ago mechanic had up on rack for oil change. Brought to my attention significant rusting of both driver and passenger side floor pans. I called Nissan and filed a claim, but vehicle is out of warranty. While they were sorry to hear I was having this problem, they would not help me. The Nissan representative I talked to said he had never heard of this problem before. I don't believe that due to the number of posts on nhtsb website and other blogs. It is a design flaw that leads to a safety issue. I think Nissan should stand behind this repair.

The VIN was not available. The failure mileage was 120,000 and the current mileage 134,000.

I have Nissan Altima 2005. I took my car to get inspected and it failed due to rust and rotting under the car. Nissan, does not repair this. In doing research I have found numerous of individuals online with the same problem with models from 02 - 06. All of Japanese cars will have this problem. I had my car from 05 brand new, I'm the only owner with no accidents. I think Nissan should do a recall on all cars with this problem and fix it. They charge you all this money for cars, they know soon will have this problem, because they don't protect the car with the under coating. Shame, shame, shame on Nissan!!!
