After seeing a report on the news this morning that Nissan Altima are having systematic issues with rusting under the floorboards, I looked under my 2005 Altima, and can see visible rusting under the floorboards. It has rusted, corroded and is flaking off. If you touch it, it falls apart. It has nearly rusted through. I understand Nissan would like to take the position that this is not a design flaw or a safety hazard with these cars, but that does not make sense. If there are hundreds of these cars with the same problem, how could it just be coincidence? I am about to have a child, and do not feel safe driving a child around in this car. I also understand Nissan issued a technical service bulletin with respect to this issue years ago, so they have been aware of the issue but have done nothing to address it for years.

My Nissan Altima 2005 wouldn't pass inspection due to rust and corrosion underneath the passenger and driver side feet area. I was able to fix the passenger side but now the driver side is even worse and causing lots in damages.

After hearing on the today show this morning complaints against Nissan regarding under carriage rust I thought I would file a complaint as well. In approx. 2012 while walking towards my car I noticed something hanging from the bottom of my passenger side. Under further inspection I noticed severe rusting and it had actually rusted completely through the floor board. The only thing holding my feet in the car was the carpet. I immediately contacted Nissan and was told oh well so sad not gonna help me because the car was no longer under warranty. I had pretty much always had the car serviced regularly at uftring Nissan in peoria Illinois. This was never mentioned in the 4 years prior to me in the many trips I made for routine oil changes and several strut repairs on this car. Yes I have had strut issues with this car from day one. They have been replaced at least 6 times since I bought the car in 2008. Anyhow, I took the car to my body guy and he replaced. The floorboard for 500 bucks and said the driver side is headed in the same direction. At this time I know of no issues with rusting on the drivers side. I personally check every time the car is lifted. However if it is rusting from the inside out it is more than possible that by the time I could visually see damage it will be completely through with carpet being the only thing keeping me inside. I absolutely want Nissan to not only pay for the first replacement but fix the problem so I am not paranoid about the seat falling through when I am driving on the road. This is total negligence on Nissan part.

Excessive rust on the front driver's side floorboard. The metal floor under the carpet is completely rusted through. I first noticed the problem a little over three years ago but it has gotten progressively worse. Apparently, this is a common issue for 2002-2006 Nissan Altima.

I have a 2005 Nissan Altima 2.5. 128,000 miles on it, couple of weeks back I found out the floor boards are completed rotted out on both sides, so bad that one can stick their hands in and feel my carpet. The mechanics were so surprised how bad they were and this was the only part of the base which was rotten. Now my car is junk and I wont even take or resell my car. Nissan autobody says it will cost me 1200 per side totaling $2400 to fix the floor boards which is obviously a safety issue and should have been recalled a while ago!! I now have no vehicle to drive and im scared of driving it anymore. And do not want to invest $2400 dollars on something that is not a wear and tear issue, its a structural issue and should be recalled!!!

Following a routine service appointment I was told that the floor on the front passenger side was completely rotted out and that it was unsafe to drive. It is a one owner car and I am a 75 year old female. The car had outstanding care. It was not garaged throughout its lifetime but it did get excellent care. Floor repair is estimated to cost over $1,00 dollars. That is money that I cannot afford.

Floor pans completely rusted through on front driver and front passenger sides. You can see the carpeting from the bottom of the car and its not even ten years old.

My floorboards on my 2005 Nissan Altima are rotting through on my passenger side. The car has about 70K miles. It is in great condition. I'm worried that my passengers feet may go through the floor. I've owned a few cars and I've never seen floorboards rot like this.it is a known problem....just google it.... I have a 1991 Toyota supra that has about 130K miles, drivien I the same conditions and ive never seen this. Nissan doesn't want to help. Ive tried Nissan Consumer Affairs and they don't care.

On a recent trip for oil change I asked the dealership about a spot of rust on the rear quarter panel. They said a bracket was rusting that holds the rear quarter panel on. The real problem, they pointed out was the severe rust under the front floorboards, both passenger's and driver's side. I was hoping to get about 6,000 for the car toward the purchase of a new one. I have always had my car serviced at the dealership. The engine runs great it is very upsetting to know that it is dangerous to drive. The Nissan dealership told me there is nothing they can do. They said there is no warranty on the rust.

I saw a tv news story about a problem with 2002-2006 Nissan Altima having rusted out floorboards. I checked underneath my Nissan Altima and the floorboard is rusted out to the point where there is a hole in it. You can put your finger in it and chip away the metal in the floorboard. This is very dangerous. This hole is only going to get bigger as the metal will rust even more.

- Lees Summit, MO, USA

The contact owns a 2005 Nissan Altima. Due to corrosion on the frame of the vehicle, a hole developed on the driver side floorboard. The vehicle was taken to an independent mechanic. The technician diagnosed that the rust must be removed and a metal plate must be welded to repair the hole. The vehicle was not repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 80,000. The VIN was unavailable. Updated 3/24/15 updated 9/18/2017

Floor boards underneath passenger sides are rotting through...why??!!!!!!!!!

- Endicott, NY, USA

Had my Nissan in for a oil change and it was discovered that both the drivers and passengers side floor boards were rotted out. There is not another spec of rust on this car. Thank goodness for carpet and floor mats as that is all that is between me and the road. Called Nissan to report issue/ask for repair and was told no. They stated that my car has never been in for service and is old therefore they would not be offering me any assistance. Explained that my B/F is a mechanic and has been the one maintaining this car and would be happy to provide them with all the service records, but Nissan didn't care. Continued to tell me that because my car was old they would not be offering assistance. I let him know through my research that people were having luck getting Nissan to pay for the repairs and he said he wouldn't confirm that which is when he pointed out my service records at a certified Nissan dealership. I asked him if that is why Nissan wouldn't cover the repairs - B/C I hadn't given Nissan all my hard earned money for the past 10 years - there was silence on the other end. For a multi-million dollar company they sure need to work on their customer service and taking care of their current customers. I have done some research on this and it appears to be a fairly common problem for 2005 Nissan Altima's. I am the 17th person is the past 2 months to complain about this issue for this make/model/yr of car on this site alone. There are many other complaints on other sites. I see a pattern here!!!!!

A couple of weeks ago I noticed something hanging underneath my car. I had assumed it was a branch or something as simple. I asked a couple of co-workers if they wouldn't mind checking it out for me. Both told me it was a piece of metal hanging below the passenger side floorboard. I took my car to the auto body shop where it was put on a lift to be inspected. I also looked at the car along with the shop's owner and other mechanic. The passenger floorboard has rusted completely through to the interior, a hole large enough to put one's foot through if it weren't for the carpeting. The rest of the undercarriage was examined then the body. There is absolutely no sign of rust on this vehicle whatsoever. I have read hundreds of similar complaints against this model for the exact same type situation.

My 17 year old daughter was involved in an accident with my 2005 Nissan Altima on May 21, 2014. She was hit by another vehicle in which she received back, leg and knee injuries. My vehicle was hit hard on the front passenger side in which the airbag did not deploy when clearly it should have by the impact of the accident and the speed of the other driver. To add, my daughter was wearing her seat belt and thank god there were no fatalities. When I purchased the vehicle I had no idea that there had been recalls on the vehicle for airbag issues. I would not have purchased it if so. In doing research I am finding out about the airbag issues affecting past and current Nissan models. The car was deemed a total loss by my insurance company. The airbag system should deploy when the restraint controller detects a moderate to severe frontal collision. In my research, I have found that some airbags fail to deploy because auto manufacturers attempts to cut costs associated with their airbag systems, which in turn reduces the quality or the quantity of the airbag sensors. I would like the NHTSA to investigate this issue. I am out a car and strongly considering retaining an attorney to handle the case..,.updated 12/03/14 updated 9/7/2017
