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.

There is a rust/corrosion hole in the floorboard below the drivers feet. I'm sure it has been there for a while but I just noticed it recently because I saw a piece of the floor dangling below the car.

2005 Nissan Altima with 60,000 miles on it needed drivers side floor replaced, dealer tried to tell me this was from snow and salt. Vehicle is located in philadelphia and not driven in this type of weather. Nissan manufactures a replacement set of floor pans but does not recognize the defect. I had to buy the set so I have the passenger side for when that rust out. This was not a cheap fix and based on age, condition and mileage, this should never have happened.

Cpsc: Many complaints are on the web from owners of Nissan Altima regarding floor boards rusting away. My 2005 Nissan Altima has such a problem even though it is garage kept. I am afraid that I will fall through the rusted out floor boards or my seat will fall through while I or any other driver is driving the vehicle. I first noticed how flimsy the floor boards were made after a week of having the car. This is a dangerous situation that the manufacturer should recall this car to fix. Please see the following web site: Https://consumerist.com/2015/04/06/nhsta-complaints-show-rusted-floorboards-in-older-Nissan-Altima-create-fred-flintstone-cars/ my friend spent over $1000 to have the floor boards repaired and I know more.

From the auto body shop's diagnostic & estimate report: "rf interior foot space sunk in more" & "floor board rusted out on both front driver & passenger sides". in other words, the metal floor panels in front of both front seats have prematurely corroded to failure, in which the floor is no longer safely supports the occupants & the barrier between inside & outside the vehicle has been breached. Upon investigation this problem is a common with vehicles of this make, model, & year. The metal floor panel & its corrosion resistance are the manufacturer's error & are a safety risk to the users. I am worried about the possibility of a foot or item falling through the floor, exhaust or other fumes entering the interior, & the car's performance in an accident.

Front floor boards rusted out both sides. Set a battery on floor board and it made floor cave in. I looked under car and half of the rusty floor board pieces fell on my driveway. No rust anywhere else on vehicle. This not safe and needs to be fixed.

The carpet on the driver side was wet after some heavy snow & rain involved this year. Upon looking underneath, the floor pan was rusting out. The driver side and passenger side both have big holes underneath. Right now, there is nothing protecting my feet from the concrete ground expect for a flimsy carpet since the rust has taken all of the structural support.

Floorboards are rotting out. The vehicle has 120,000 miles on it. Very dangerous to have a foot push through and even undermine body integrity of the vehicle.

2005 Nissan Altima at recent annual safety inspection my mechanic informed me that the underside of my Altima had severe rust/corrosion eating away at the frame and floorboards. It was bad enough that he had to call his service manager to understand what to do or was the car deemed safe to continue to drive. Eventually the floorboards will fail, anyone know if this is normal for 2005 Nissan Altima?

My car has a severe floor rust problem. Specifically passenger side floor has big whole and mechanic suggested you may have your feet on road while driving. I just had a baby and I am really scared about this car. Nissan sucks big time. I will never buy Nissan again until and unless they own up the problem.

Multiple owners have complained about a rusting floorboard. This is a Nissan defect. I learned today from the mechanic who did the cars oil change that I have the same problem on my Nissan with both passenger and driver floorboards rusted and have hole in them. I have never seen this in a 10 year old modern car. Just came from an oil change and the mechanic happened to see it. Any help from you would be appreciated. The repair runs into the thousands with the car not even worth that much any more.

The driver and passenger floors are seriously rusted with holes. I found the condition when I noticed something hanging under the car. It was some sort of plastic material that lined the metal floor inside the car.

As the original owner of this Altima, we were alarmed when our son said he could see the carpeting hanging through the bottom of the vehicle. We contacted our Nissan dealer who said the repairs wouldn't be covered and to pursue it with Nissan corporate. We paid out of pocket for the repairs (safety concerns) and formally requested reimbursement. I received a call and was told it was declined due to vehicle's age and due to the fact we're in the "North-East salt states". I asked why 2005 Honda's, Chevy's and Buick's from the same locale aren't experiencing the same issue?? when I asked for a detailed denial of my claim (one citing the reasons I was being given verbally) I was told absolutely not and that Nissan would only supply a "general" letter of denial. Seriously"? does anyone else think this sounds like an unethical practice? all of these similar stories and yet Nissan hasn't been called onto the carpet"
