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!

Noticed metal hanging off bottom of car on the passenger side while it was parked in a parking lot. Got home and discovered that the coating underneath the car is peeling off and that the floor board is rusting through. At 10 years old, this should not be happening. I have a 16 year old car and it is fine. This car was recalled and treated not long after I bought it because I live in a salt state. This is a safety issue as a passenger could fall through the bottom of the car. I will be contacting Nissan on Monday but I doubt they will do anything about it. (Altima 3.5 sl-V6)

As you well know by now, the numerous documented issues with 2002-2006 Nissan Altima has alas reached my Nissan Altima. Floorboard is rusting intensely but I am not do rich so can't afford the thousands of dollars that every mechanic (I paid to inspect by the way) is quoting me. Nothing much to add to this description because no one is going to do anything about this anyway. Issue has been on local newscasts so my insignificant contribution of filing complaint is strictly to join the cause in mind and spirit. By no means trying to sound insensitive instead truthful; it's clear someone will have to die before things change, just hope isn't is me.

In 2013 I took my car to an auto body shop to have them fix my bumper and they realized a hole underneath my passenger floor. They told me it was completely rotted through and I had the problem fixed at the cost 700 dollars. Now its 2015 and I'm having the same problem all over again. I don't really want to put this money back into this car if it's just going to happen again 2 years. Nissan really needs to figure out what they're going to do with this problem. I see a lot of other people having the same problem and they're doing nothing about it this is a safety concern someone could possibly fall through the floor.

When I was working on the brakes on my 2005 Nissan Altima, I placed my floor jack underneath the car I realized the drivers side floor board is starting to rust through to the inside of the car. When I went to passenger side the floor board was starting to do the same thing. Both sides are starting to rot all the way through to the inside of the car. I find this unbelievable that a car that is so well kept could have this problem. This is something Nissan needs to recognize as a design flaw. I have had other vehicles that never had floor boards rust away so prematurely. If Nissan does not recognize this as a design flaw this will be my last Nissan bought from the car company. I have been very loyal to the brand. I can't even imagine what the repair cost would be.

  • 90,000 miles
The entire floor in front of the front seats is completely rusted through to the point that you can see the road underneath the car. Ever since I purchased the vehicle the floor had holes in it (found right after I had already bought the vehicle). This is a hazard for the passengers, very common amongst Nissan Altima and should be addressed by the manufacturer. This issue makes the car unsellable since it will never pass inspection unless a major repair is done to its body. It is unacceptable that a car would have structural issues like severe rust and Nissan not do anything about it and the NHTSA not make Nissan buy the affected vehicles back.

I brought my car to Firestone to have numerous repairs done on my car 6/27/15-6/30/15. While they had the car up on the lift, the tech noticed and told me that my floor boards are rusting out and he could see clear through to my carpeting. My windows have been repeatedly getting dirty from the inside and I could never figure out why. I have asthma and I am very concerned about the fumes that are entering my vehicle. This now explains why I feel the need to use my inhaler more frequently when I'm in my car or getting out of my car on shorter trips. For instance, I have a 1.5 mile ride to the train for my commute to work. By the time I get to the train, I'll need to use my inhaler again already. My car is paid off. I had planned to keep this car as long as I possibly could so I can pay down debt. Also, I had just this past weekend spent around $700 in repairs on my car. I've taken very good care of my car (I.e., regular oil changes, tire rotation, etc.). I just want Nissan to fix the problem so I can keep my car. Other than this issue, I love my car. I've had very few minor problems with it over the years and I'm overall very happy with it, except for this issue. I hope you can get them to help everyone similarly situated...updated 09/03/15

This past week I had my car to the dealer for an oil change and battery. Then I took my car in for brakes. When I happened to look at the bottom of my car, I found that the floor on both the driver and passenger sides was rotting out. The dealer is always looking for problems when you take it in, but nobody mentioned the rust problem. Now I have the unexpected expense of repairing the floor. After doing research, I found out that Nissan has known of the problem for a long time now, but refuses to reimbursement or do a recall. It may not be a safety hazard, unless your foot goes through the floor, but something is not right.

I had been aware there there was some rust on the driver's side floor pan. My Altima was recently taken to my mechanic and put on the lift for some maintenance and my mechanic took pictures to show me how extensive the rust had become. A significant portion of the floor under the driver's feet is missing and a large piece of metal is hanging down. The mechanic also noticed that the passenger side now has a small patch of rust.

Just found out my car's floor boards are rusted through. I did some research and saw this is a common problem with Altima's from 2002-2006. It was not caught by my oil change people, and only came up today as I was getting it approved for a sale. This repair totals the car, which obviously put a financial hardship on me.
