2006 Nissan Altima in excellent condition with the exception a significant structural defect. The floor panels on both the driver and passenger sides are severely corroded. This came to my attention while the car was at an independent auto shop for routine maintenance. The car has been well maintained and cared for. With the exception of the rust problem, the car is in excellent condition. It is incredible that the floor pan of a fastidiously maintained, modern unibody automobile would rust out almost completely within eight years. After a little research, it became apparent that this is a common problem for the 2006 Altima. Nissan is aware of this dangerous issue but they have no intention of rectifying it. Representative at Nissan usa with whom I spoke informed me to bring my car to a Nissan dealership for an estimate of the necessary repair. I brought the vehicle to decormier Nissan in manchester, ct and received an estimate of $1,700 plus tax. I again called Nissan North America and my case was transferred to the Nissan regional office. The representative informed me that my car was out of warranty and that the rust was due to salt applied to the roadways in ct, therefore Nissan would not be offering financial assistance in the repair of my car. She suggested that I pay for the repair out of pocket and wash the undercarriage regularly. The car is washed often. By hand during the temperate months and during the winter months at a car wash where the undercarriage is also washed. I have owned, driven and cared for a number of imported and domestic vehicles within the state of Connecticut for many years and have never experienced this type of issue. After research, it became evident that this is a common problem for this particular vehicle that has recently surfaced. Nissans response and lack of culpability pertaining to this issue is absolutely unacceptable.

My 2006 Nissan Altima's floorboard is rusting through on the drivers side. This is a known defect that Nissan takes no responsibility for and my local dealership admitted as much. There is an engineering defect that causes this particular spot to be vulnerable to rust. This could become a safety issue.

I was coming off 295 and hit a patch of black ice lost control of my car and hit a guardrail. The air bags never went off and everyone at the scene was trying to figure how or why they did not go off. My car is totaled.. updated 02/19/15 updated 3/30/2016 updated 9/20/2017

- Taunton, MA, USA

I checked the underside of my vehicle only to find that the floor board was rusting out heavily on the driver side. I checked online and saw that there has been many complaints about this and that Nissan refuses to address the problem. Very upset about having to fix this.

- Piscataway, NJ, USA

Floor boards rusted totally thru on drivers side and passengers side. Only thing stopping feet from going thru the floor is carpet.seems to be a ongoing problem with the floors on Nissan, I believe this is a very dangerous problem that should be corrected by Nissan as a recall safety issue.

There is rust under the driver and passenger floorboards.

- Farmington Hills, MI, USA

The contact owns a 2006 Nissan Altima. The contact stated that the floor boards were completely corroded. The vehicle was taken to the dealer. The technician verified the failure and stated that the floor boards needed to be replaced. The manufacturer was made aware of the issue. The failure mileage was unknown.

- Chillicothe, IL, USA

Took vehicle in for state inspection and didn't pass. Vehicle driver side and passenger side floors were completely rusted out. Not safe!!!! dealer said it is not covered (of coarse). Quoted $800 to repair. Dealer acknowledged that this is not the first time they saw this. This is the only rust on the car. I see multiple other complaints about this problem with this year (and other years) Nissan Altima. Dealer should of warned me about this since I take the car there every year for inspection. This did not just happened this year. There should be a recall.

In 2006 we purchased a new 2006 Nissan Altima 2.5, VIN#[xxx] was kept in the garages ever since it was purchased. The car has 70,000 miles and looks like new. On October 26, 2014 my husband was rotating tires when he noticed that floor boards on both sides were corroded & rotting. We were horrified since this car is only 7 years old, well maintained, and garage kept! this did not make any sense so we searched the internet & found out that other people reported the same issue. www.carcomplaints.com/Nissan/Altima/2005/body_paint/floor_pan_rusted_through.shtml 2006 Altima 2.5 had issues with the metal that was used for the floor boards & this was a known issue. The holes in the floor create danger for the car occupants! on October 27, 2014 I contacted Nissan N America at 1-800-646-7261 "? case 16414850. They asked me to take the car to the Nissan authorized dealer?"S body shop & get an estimate to replace rotten floor boards. The estimate was $3,334.66. I called Nissan N America rep. [xxx] and gave him the estimate. He said that Nissan would cover up to 50% of the repair cost. I told him that is not fair since the problem did not result from our fault. The fault is with Nissan, because they used poor material for the floor boards and that is well documented on the internet. He said that there is nothing more that he can do. I'm writing to you and asking you for help. We want Nissan to cover the whole repair cost because the fault is with Nissan product, not our maintenance.

Driver lost control of the vehicle and went into ongoing traffic and was T-boned by another vehicle. Both vehicles were going 45 miles per hour. No air bags deployed. The front airbags, nor the side airbags deployed. The passenger door came all the way over to the gear shift.

Reported to Nissan in early Sept 2014. Case number [xxx]. found while I was doing a brake job where car was elevated with car jack and I noticed the undercoating of the car "bubbling" downward and started knocking the loose material driver side floor board section approximately 8" X 12" completely rusted through where the underside of the floor mat was visible. Passenger side was ok. Seems water can work into some under-car seams, get trapped, lay, and begin to rust over time. Despite argument that a rusted through floorboard constitutes a safety issue, Nissan declined to participate in $480 repair citing rust warranty limited to 5 years, 60,000 miles. It was noted that local Nissan dealer was well familiar with the repair (their quote $637.81). Repair down at an infiniti car dealer body shop for $480.03. Found approximately half of body shops contacted respectfully declined to quote a "rust" issue. Information redacted pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6).

Floor boards rusted out.

- Lower Burrell, PA, USA

The driver and passanger floor boards are rusted. Like many other 2005 Nissan Altima's. the heat in the car also only runs warm when the vehicle is moving. If the vehicle is at a stop the heat blows cold.

- Peekskill, NY, USA

Passenger floor board is rotted through, noticed it today when my passenger was in the car and his foot dipped down the hole that was created. Looked under the car and the only thing keeping the passengers foot from hitting the pavement is the carpet, this is unacceptable on a car, it is a safety hazard physically and it could lead to fatalities due to exhaust fumes entering the vehicle. I have researched this issue online and it seems to be a fairy common issue with 2002-2006 Nissan Altima. Took my car to the local mechanic and he said that this issue needs to be fixed soon as there is a chance that the carpet can catch on fire burning the enitre car.

- Lombard, IL, USA

While getting the brakes repaired, we noticed a huge area of rust/rot under the passenger side of the car. The rot area is approx 22 inches in length and about 10 inches across. Other then the high mileage, the car is in perfect condition. This issue makes me concerned for my safety and the safety of my passenger. In researching online, it looks like this is a known problem with Nissan Altima.

- Marlboro, NJ, USA

The contact owns a 2006 Nissan Altima. While the vehicle was being inspected, it was discovered that the front driver and passenger side floorboards were severely corroded. The vehicle was not diagnosed or repaired. The manufacturer was made aware of the failure. The failure mileage was 100,000.

- Millbury , MA, USA

During a routine brake inspection, my mechanic found that sections of my vehicle's floor approximately under the driver and passenger's feet are severely rusted. It is bad enough that the underside of the carpet/insulation is exposed in spots. I was shocked to discover this issue as the car has less than 100K miles and has no other rust or corrosion problems. After some searching on the internet, it is apparent that this is a very common problem with this particular make and model of vehicle and to my knowledge the manufacturer has not initiated a recall. At this point I am faced with an expensive repair on what is absolutely a safety hazard due to a poorly engineered and manufactured design.

- Rock Island, IL, USA

As I was finding a spot, to place my floor jack, to replace the front brakes, I noticed a rust spot. So I went under the car and noticed the floor pans under the front seats are almost completely rotted out. The car isn't 10 years old yet and barely has over 100,000 miles on it. Within the next year or so it more than likely wont pass inspection. This is completely unacceptable.

- Fairview, NJ, USA

Vehicle in for annual inspection - it did not pass secondary to extensive rust on driver and passenger side floor boards. Car is garage kept year round and not driven in winter (end of Oct - beginning of April). Car has never been in an accident and has been excellently maintained. No other issues whatsoever with vehicle. Quick search on internet and immediately saw many identical reports including video documentation. This is very upsetting and inexcusable for a car of this age driven in fair weather conditions. Nissan really needs to cover this defect.

- Sarver, PA, USA

I have a 2006 Nissan Altima - great condition, garage kept car - floor boards are rotted out on the driver and passenger side where a "plug" is suppose to be. Nissan dealership said that some of the cars got sealed and have no issues where other cars were not sealed and those ones are rusting away like mine. I have no other rust on this vehicle.
