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!

My 2005 failed safety inspection because the floor boards are rusted through. There have been several complaints on the issue. Every mechanic I brought it to for a quote said there should be a recall. Nissan is not willing to help it customers with the repairs. When are you guys going to step in and force Nissan to address this safety issue?

Altima 4-cyl

  • 192,000 miles
While changing my oil I inspected the underbody of my car and noticed a rusted out area of floorboard on the drivers side. I checked further saw that an area the size of a large grapefruit is completely rusted out. I looked at the passenger side and see the start of the same damage due to rust. There appears to be a drain hole where the rust starts. On the passenger side you can see the original drain hole and the rust starting around it. On the driver's side, the rust is extensive enough that the drain hole is simply gone. In talking with repairs shops and checking the internet I can see this is a common issue with Nissan Altima's of my design - 2002- 2006. Since this is a safety issue (allows fumes in the car if carpet wasn't there and could be structural in case of an accident) caused by a design issue (open drain hole in the floor trapping salt/water), I'd like to see Nissan issue a recall to repair. Thanks

My 2005 Altima was in the driveway when my son noticed a large piece of rust under the passenger front floor. I pulled up the carpet and found a 6" by 16" hole in the floor. I contacted Nissan for goodwill which was declined. I was a Nissan certified master technician for 21 years and a service manager for the last 2. my wife and I have personally owned 10 Nissan's and my immediate family owns 3 more. Nissan said its an environmental issue. My car is in a garage and in otherwise great shape. During my tenure with Nissan I've seen multiple Altima with this issue. I believe its not environmental but actually because of the sunroof drains draining directly into that area of the floor to drip out of a seep hole. This is a very dangerous condition. If something comes up off the road the only thing protecting you is the carpet, not to mention the fact your feet can go through to the ground below.

  • 121,000 miles
I own a 2005 Nissan Altima with 121,000 miles on it. I am the original owner, this car has been well taken care of and garaged most of its life. I was shocked to find out last week, that while a oil change was being done, that both the drivers side and passenger side floor pans are rusted out. After doing some research, it appears this is a huge problem and Nissan is not accepting responsibility for a manufacturing defect. I have had most of the maintenance of this vehicle done at the Nissan dealership. Never once did they point out this problem, which has been evident for many years based on the damage. I could have made arrangements to fix this sooner. It is a huge safety problem in my opinion. I do not feel it is safe for my family members to drive due to fumes and the instability of the floor. I am in disbelief Nissan has not been held accountable. I do have pictures if anyone would be interested in seeing them.

Altima 6-cyl

  • 130,000 miles


When performing maintenance on my Nissan Altima, noticed two large rust areas originating from drain holes located underneath front driver and passenger side floorboards. The rusting is severe, with large flakes breaking away when touched. The vehicle has no rust anywhere unusual on the body or the chassis, and where there is rust (along weld points of chassis) it is not comparable to the degree of corrosion. Contacted Nissan usa, they instructed me to seek dealer review. Dealership service manager reviewed and photographed, then denied assistance by citing the age of the car. I forward the decision to Nissan usa, and they contact me by phone to politely inform me that they are rejecting due to the car being out of warranty. I informed that this is a very common issue and that the vehicle is otherwise structurally sound, but she repeated that regardless if the rust originated from a defect from Nissan, the fact that it is out of warranty leaves her unable to assist. The vehicle is owned and driven in the mid-atlantic region where there is surface snow in the winter, but the undercarriage is sprayed down regularly to remove corrosive salt spray. This rusting was not visually present as of 6 months ago, but is now rapidly eating away at the metal at the surface.

Altima 4-cyl

  • 105,000 miles
I contacted Nissan usa to try and get them to open an investigation for the floor boards rotting away in my car. Did some research online and found out that I am not alone in my problem with the floor boards. Numerous people online with 2002-2006 Nissan Altima have the same problem where there is a snow covered winter. The women that answered the phone from Nissan usa was very polite took my information and looked into what I would have to do next to start things off. She told me that I would need to have the vehicle diagnosed by my local dealer. So I made the appointment. A few days later had my estimate for repairs which is one thousand dollars plus tax. I called Nissan usa back and she politely filled in the details of the repair and instructed me I will be getting a call from a regional specialist. A few days later get a call from said specialist only to find out that they will not help me because my car no longer has warranty coverage. I explained that I want to have this investigated as the floor boards of a car that is built in 2005 no matter what should not resemble a 1960 Chevy floor boards. Again was just told there is nothing Nissan is able to do I have no warranty. This is a safety issue as the floor boards that are rotting away are directly where you feet are in the front seats. Please look into this as it is an issue for I am sure thousands of Nissan owners.

Front passenger side floor board is rusting out badly with a big hole in the floor.I am worried that either someone's feet will fall through floor or there could be a case of carbon monoxide poison. I contacted Nissan headquarters and mastria Nissan dealer on 5-30-14 and was told, " there is no recall on this, so they will not fix this issue".the dealer did say, " they have heard about this issue on many Altima and have fixed it in the past for a cost of $755 per floor panel".I told them, " if you know about this issue, why should I pay to fix it."

After hearing a suspicious noise on the driver's floor, I checked underneath. The driver's side appeared to be ok, but pushing down on the carpeting you can feel the damaged metal. Underside the front passenger side there is a 24" long badly rusted through area that will have to be repaired. I'm guessing the noise on the drivers side is from rusted flooring as well. This car has been owned since new, well-maintained and garaged nightly. But it has been driven for 9 winters in the snow belt. Still, the rest of the vehicle is in excellent condition with no rust other than in those two frequently complained of areas.

I took my Nissan Altima for inspection. The mechanic found the driver side floorboard to be rusted out. I am the original owner of the car and it was purchased with the dealer undercoating included. I am glad it was found before my foot went through the floor while I was driving. I checked with the Nissan dealer I bought the car from and he was familiar with the problem. He informed me that Nissan has not issued a recall for this problem.

I own a 2005 Nissan Altima SE-R the car has a clean carfax and I purchased this vehicle used form the local Nissan dealer with 15,000 miles. I am a automotive technician and noticed about 8 months ago while performing a routine oil change vehicle had around 101,000 miles that there was 2 rusted spots underneath the front of the vehicle where the front passengers floor boards are the floor board was cracked slightly. I took note of it and continued on my way. Well I just performed my routine oil change now have 105,000 miles on the vehicle and again noticed those same 2 rust spots are now rotted with a hole about the size of a soda can, there is nothing I can do to prevent this from happening also note that the part of the undercarriage that is rotting was treated from the dealer with a coating to prevent this from occurring. Obviously this should be a defect from the dealer and should be recalled as it will continue to rot the passenger floor out of the vehicle. Anyone with a 2002-2006 Altima should have there vehicle checked for this as there have been numerous complaints about this over the internet. Contact the Nissan cooperation and complain we together should be able to get this recalled.

Altima 4-cyl

  • 140,000 miles
We were told last year there was a hole the size of a grapefruit in the underbody, under where the passenger's feet would rest. I looked into getting it repaired and noticed a lot of similar complaints online, with others asking why it was not recalled due to the volume of such defects. Today I brought my car in to check on a noise, and was told the hole has increased to the size of a breadbox and that the brake calipers are therefore rubbing on it. The first estimate I received to repair the hole is $2500, as the body shop will have to cut out the affected area and solder in a new piece. While I live in the midwest, we wash the underbody in winter, and I don't think this should be happening on a 9 year old car.

I took my Nissan Altima to my Nissan dealer to have an "check engine light" repaired. They told me that my floorboards had rusted out and would not pass state inspection. The car shows no visible sign of rust anywhere on the body. This must be a design defect because cars do not rust out anymore. How can you help me? thanks.

The floor pan for my Nissan Altima have rusted out making it dangerous. After spending 5 mins on the internet, I learned this is very common, affecting 1,000's of 2005 Altima. It is always in the same spot and Nissan refusing to acknowledge poor craftsmanship and defective product. Holes allow exhaust fumes into my car, making dangerous for my children to ride in car. Totally unacceptable.

We noticed rust colored stains on the garage floor where my car is parked, so my husband jacked up the car and saw a huge rusted area in the front passenger side floorboard. It was so badly corroded that he easily put his foot through it! we bought our 2005 Altima new in 12/2004 and it only has 81K miles on it. The car has always been garaged and washed and detailed regularly. Apparently we are not alone based on what we've read online. A nine year old car should not have rusted out like that!
