I had my 2005 Nissan Altima at my local mechanic to have some rattling underneath my car looked at. There was a loose heat shield that the mechanic fixed and he also notified me that there were large areas of rust along both floorboards. This vehicle has been meticulously maintained and washed in the winter. The last time the car was at there mechanic, there was no rust evident. Unfortunately my car is no longer under warranty and I would like Nissan to acknowledge that this is a manufacturing defect.

My vehicle is a low mileage garaged 2005 Nissan Altima which is in perfect condition except that the driver and passenger side floor boards are rotted out so that you can step through. Vehicle has been garaged and meticulously maintained with fresh water cleaning of the undercarriage when washed and especially in the spring. This is a serious safety hazard with potential for injury stepping through and possible death from exhaust fumes causing unconsciousness while driving. This is an obvious vehicle defect and should be recalled. I have read numerous incidents of this problem both on this nhtsb site and in owner forums so it is a well known problem that needs top be addressed.

After jacking up my mother's car for an oil change, while I was placing jack stands behind the front wheels in the appropriate jacking points, I noticed that the floor panels looked swollen underneath the rust proofing material. I began to poke at it with my finger, and my finger pushed through the rust proofing and all kinds of severely rusted metal began to fall out on the garage floor. The steel floor panel, had basically turned to rusted dust. I was able to push my finger up through the floor panel until I could feel the bottom of the carpet. Noticing no other rust anywhere else near by, I figured it had to be a manufacturing defect, so I decided to check the driver's side same location, and sure enough, was able to push my finger through the rust proofing and through rotted steel like it was nothing. This is obviously a manufacturer defect as there is absolutely no rust anywhere else on the car. The car has very low mileage, and has been very well maintained, as well as garage kept. Nissan needs to acknowledge this as a manufacturing defect, and a safety issue.

Today while performing an oil change on my girlfriends 2005 Nissan Altima I noticed a large hole in the floor of the car. There is a large rusted out hole, only on one side of the vehicle that goes completely through to the inside. In exactly the same place on the opposite side of the car there is no rust at all. This car is washed regularly, and has no rust on the paintwork anywhere. Upon looking it up on the internet there appears to be many many people with this issue, and Nissan is trying to cover it up and not cover the replacement of parts that are clearly defective. Please help me hold them accountable.

My 2005 Nissan Altima 2.5S has 88,500 miles on it. It is in excellent condition, except for the floor pans under the vehicle (driver and passenger sides) that are rusting through. It is apparent that this is a known problem for these vehicles and Nissan has not issued a recall. I need this fixed, as this is a safety concern for 2 reasons: Structural integrity and fumes entering vehicle. I was informed by my local Nissan dealer that the only proper repair is to completely replace the floor pan metal. The estimate for this was around $2500. I have a 2 year old son and a daughter on the way. I cannot afford a new vehicle at this time, and Nissan needs to step up and fix this!

While jacking my 2005 Nissan Altima up upon looking underneath I noticed a 4 inch by 4 inch patch of rust. After further inspection I noticed that it was rusted all the way through to the carpet inside the car. Six months ago when I was working on my car there was not rust at all. I take care of my car and inspect the car for any problems. There are no recalls for this by Nissan and this needs to be fixed. After researching I found this is a common problem with 02 - 05 Altima and is a serious safety issue.

I have a 2005 Nissan Altima sl and took my car into conicelli Nissan back in February of this year for an order change and something else minor. Conicelli Nissan brought to my attention that the floor pan was rusted on the passenger side front. I was told to contact the body shop of conicelli which I did and they in turn told me that they can not do the repair because of the rust and they didn't want to be held accountability for it and perhaps risk a law suit further down the line. My complaint is the car is only 8 years old with 60,000 miles on it and I have taken it to two different body shops and they are amazed that the floor pan has rusted already being that the car is only 7 years old and in very good condition. This seams like a known problem with Nissan cars and it doesn't make any sense and the customers want answers now. It will cost me at least $1,000 to get this taken care of and I don't have that kind of money. I need someone to contact me to get to the bottom of this ongoing issue.

I have a 2005 Nissan Altima that I just took in for a front end check and was notified that the floorboard on the driver side is completely rusted out, I can actual touch the carpeting through this large hole. I can not believe this, the car is only 7 years old. I have searched this on the internet and it seems to be a very common complaint, why isn't Nissan do anything about this" how many complaints need to be made before something is done about this" obviously this a manufacturer defect.

I purchased my car in January of 2006 used with about 3,800 miles. I've taken my vehicle several time to Nissan dealer for my 15,000 mile service and also they replace my suspension on a recall. I discovered today that my front passenger floorboard is completely rusted out, I mean if it wasn't for the interior carpet I could put my whole arm down in the hole. I've done research and it seem to be a very common problem with model and year. Nissan has lifted my car numerous time and has not once mentioned seeing rust, which at this point is now out of warranty. This could've been fixed and still under warranty months ago. I was my car all the time and even in winter, I understand that rust is natural on a car, but when you see that this happens more than often on this particular model they should do something about it. Either extend the warranty out further or recall. My car is no even that old and this is upsetting that I going to shell out some major bucks to get this fixed properly.

What once was two decent sized rust areas on the floorboard of my Nissan Altima is now two gaping holes in which you can see and put your hand straight through and touch the ground outside if it wasn't for the carpet. I first noticed it when I was getting an oil change and my mechanic pointed out to me. The it all made sense because when ever it rained or snowed badly in my area I would always have wet floors and at first I thought something was leaking but I now know it's the two rust corrosion spot in the floorboard. And some days the odor from the wetness on the carpet is pungent. One is on the driver side and the other is right on the passenger side. I was looking through my warranty and vehicle info books that came with the vehicle and it definitely shows that rust warranty is lifetime or something to that nature I am going to look at it once again and ensure if that information is correct.
