Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety. 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!

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?

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.

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!

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 contact owns a 2005 Nissan Altima. The contact stated that the driver's side floorboard would become wet whenever it would rain. The contact ran water down the windshield and opened the hood to see if water was entering through the dashboard area, but to no avail. The vehicle was not taken to the dealer for inspection. 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!!!

Went to get my first inspection after purchasing the car and it failed and I could not get sticker. It failed because I have large rust holes on both the drivers and passengers side floor pans. On the driver side, the carpet is exposed to the underside of the vehicle which presents a safety risk as my foot could go through it while driving.

Vehicle was in for repair at local automotive repair shop for crankshaft position sensor replacement. During repair, mechanic had vehicle up on lift and noted severe rust to the floorboard area of both driver and passenger side. Rust damage is so severe it is rusted all the way completely through. Upon my personal investigation via the internet, I found numerous complaints from other individuals noting the same severe rust damage to the same location (floorboard) of their Nissan Altima as well. It is my opinion that this is a safety issue and should be addressed immediately by Nissan.

I just discovered that the floor boards of both passenger and driver side in the bottom is fully rusted. It seems after looking on line that I am not the only owner of the 2005 Altima with the same issue in which could lead to a safety problem with the structural integrity of the vehicle.

I had discovered the floor on the passenger side of my Altima rusting through from the inside. When originally purchased new the auto was discover to have a water leak soaking the carpeting on the drivers side and the passenger side of the car. Nissan (dealer) had indicated that they found the source of the leak but evidently had not with the floor rusting through from the inside of the vehicle as stated. It seems after looking on line that I am not the only owner of the 2005 Altima with the same issue in which could lead to a safety problem with the structural integrity of the vehicle.

My 2005 Nissan Altima floor board is badly rusted. I cannot pass the state inspection and it will cost me so much money to fix my car just to pass the inspection. I did some research on line and I see that most 2005 model has this issue. I feel that the dealer needs to do a recall and fix this problem immediately. I will most definitely not recommend this make and model to anyone else.

The contact owns a 2005 Nissan Altima. The contact stated that after exiting the vehicle, she noticed that her pants had become wet. After inspecting the vehicle she noticed that there were holes in the frame under the vehicle. The vehicle was taken to an independent mechanic for diagnosis where the contact was informed that the frame was corroded. The corrosion was so severe that the vehicle was deemed as unsafe to drive. The dealer was notified but offered no assistance. The manufacturer was notified and advised that the corrosion failure was to be expected because she resided in the new england area. The vehicle was not repaired. The failure and current mileage was 64,000.

I took my vehicle for an oil change and the technician showed me that my floor boards under my driver and passenger side seats were rusted out and forming holes into the cabin of my car. He was able to poke all the way through and push up my carpet on my driver side floor. I was issued a factory recall around 2008 from Nissan about living in a road salted state (NJ) and the undercarriage needed to be replace. I brought my car in for the recall in Nov 2009. It seems they did not replace all the affected areas. I contacted Nissan today via their 1-800 # and was told there was no longer a warranty or recall out for my vehicle concerning this issue. I drive the Nissan as my main transportation for my children and I can not afford to fix this issue out of my own pocket. It is unsafe and unexpected from a 7 year old car purchase brand new.

Fully rusted driver and passenger floor boards. Can see interior rug underneath vehicle. Have done a lot of research and this appears to be a known issue with Nissan from 2002 and 2005 related to cars in salt states. Have seen many comments that defective steel was used. We have been advised that the structural integrity of our car is compromised. Dealer wants $1200 to cut out rotted floor boards and weld in new floor panels. Have contacted Nissan customer care and opened case. Regional manager called and refuses to offer any coverage for this issue. Also, Nissan as a corporation has decided that they are not going to offer any assistance to owners with this widespread problem.
