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!

Altima 6-cyl

  • 75,000 miles


Took the car to repair shop for O/C and was told I had slight rust underneath passenger door. Was told it should be alright for another inspection. When I went for inspection I was told they couldn't inspect it because the rust had gotten so bad in that same area. I paid close to $500. For repair and was also told by others that it was a common complaint for that year car and that it was a design flaw and has been since has never been run in the salt and was told it was water getting up inside the are mentioned because of the design flaw and sitting there to cause the rust. Was really upset about this considering the car is in fantastic shape.. I think Nissan should help for the repairs... I also was told I because it was a safety issue the car didn't have the 10 grace period from registration to inspection, so I did it immediately.

Altima 6-cyl

On August 18, 2014, after dropping my son off at school. I came to stop at a traffic light and when the light changed, I started to take off and noticed the car has shut down. I eventually made it home with the car going a very low speed and then speed up, but when car to a start the engine stalls. The vehicle was put on a computer to see what the diagnosis were and it was the camshaft sensors and crankshaft sensor costing $80 dollars for two and $70 for another, however these items has been changed along with a tune up and the car is doing the same. After doing some research on the computer, I noticed there were recalls on the crankshaft sensors and the ECM. I contacted Nissan dealer, an appointment was made and I was told that my VIN number is not showing so the problem had to been done, because I'm the second owner. It's funny how this problem comes about after 4 1/2 years of having this vehicle and the recall suppose to have been taking care of with the first owner. This is an inconvenience and it's frustrating. There is also rusting of the floor under the car, you can see the floor coming down from under the car on the passenger side. This is an outrage and something needs to be done at the cost of the dealers and not the owners. This is dangerous, you can be driving at a speed and the car just stop, which can cause a very bad accident.

Vehicle floor boards have rusted through. This was discovered when I brought the vehicle in for service and was advised by the mechanic not to drive the vehicle as there were 12 inch holes in the floor boards on both the driver's and passenger sides and it was not safe. I filed a complaint with Nissan customer service and was informed that they will not provide any assistance in repairing the vehicle.

Altima 4-cyl

  • 80,000 miles
2005 Nissan Altima with 80,000 miles on it. My father took his car into be inspected and they will not pass it because of the floor boards completely rusted out. After researching this online, there are millions of dissatisfied Nissan owners who are battling this very problem. Now, if my father cannot get his car to pass inspection, he cannot use it. So far, Nissan has not done anything to help with his issue. My father has called countless repair and body shops and no one will repair any rust. Not even the dealership. The customer service rep at the Nissan dealership was nothing more than rude and insensitive but did tell my dad that there have been numerous complaints and repair questions about rusting floor boards. I have seen people call Nissan corporate headquarters with the same "sorry" response. Nissan is looking at a very large class action lawsuit which I will pursue to the fullest because of their lack of respect for their customers and for their craftmanship, lack of concern, lack of solutions. I hope I am joined by anyone else who is battling this problem, leave your complaint here, and hopefully some help will be coming soon!

  • 25,000 miles
This car has very little milage only 25000 miles (42000km) and the passanger floor board is rotted out. I believe that this weakens the body integrity of the car. The rest of the car has not rust what so ever. This seems to be a design fault in the car as thier are quite a lot of complaints on floor boards rotteing out on Nissan Altima 2002 to 2006. I feel Nissan should admit to having design problems for having floor boards rotting out prematurely.

Altima 6-cyl

  • 112,737 miles
My car failed MA inspection because the driver side floor pan is rusted out. The hole is approximately 12 by 10 inches. I found many complaints on the web for the same problem. Nissan refuses to take responsibility. Nissan claims it is caused by salt in the North East, but if that was true, the entire floor pan would have rust, not just isolated to the front driver side. Let me repeat, the rest of the floor pan is flawless, no signs of rust whatsoever. Clearly this is a design or manufacturing flaw. Some customers have both front sides rusted out. My passenger side is fine as the assembly line "hole" has been properly filled in. I have to assume the driver side was left open. There are many pictures on the web showing earlier phases of this problem showing that the rust started at the assembly line hole. Basically, this small hole (1 inch diameter) allows water into the interior. The noise dampening material and carpet soak it up. The wetness goes undetected by the driver because the floor mat has rubber backing, thereby showing no signs of wetness. As with any perpetual metal wetness problem, rust eventually becomes a major problem. Please make Nissan take ownership of this problem. Thank you.

Took my car in for state safety inspection and was told the passenger side floor was rusted thru - I couldn't believe it - had to have the repair completed to pass inspection, now reading numerous complaints that it happen to others - Nissan needs to rethink the recall on this or reimburse for the repair - not cheap to have done!!!!

Altima 4-cyl

  • 85,000 miles
Dropped car off for state inspection. Was told the driver side and passenger side floor boards were rusted through. Not able to pass inspection because of this safety issue. It allows fumes to enter the car and weakens the floor for possibly putting foot or feet through floor board. Definitely a design flaw and safety issue. Nissan should pay or help pay for this defect.

Just found out the undercarriage of the car is rusted, after researching the issue, I learn that most Nissan Altima owners experience this same safety issue! this is extremely dangerous as the inside floor becomes weak and can cave in from the rust if not repaired. Repair of this issue is costly and I've read that Nissan does not consider this a craftsmanship issue but normal wear and tear. I've never heard of 20th century cars rusting out in this manner, I'm very disappointed in Nissan not backing their product!!

2005 Nissan Altima with 108K. Just noticed that both driver and passenger floor boards are gone. Rusted all the way through, the only thing there is the carpet backing material showing under the car. This is crazy to have a car with just over 100K and have the steel floor gone. Most certainly a safety issue.

I was looking at my car and notice that the floor panels for the passenger and driver are rotted away. After looking at the rest of the car its clear that its not your everyday rust. After doing research online there are hundreds of other people with Nissan Altima's that have the same problems. How is this not a recall by now.

I own a 2005 Nissan Altima 2.5S with 127,000 miles. I noticed rust particles on my driveway and inspected the bottom of my car and discovered that the floor boards on the driver and passenger sides have completely rotted/rusted out. This should not be happening on a car that has been properly maintained. This is a safety issue because of the possibility of fumes and the instability of the car's floor. Nissan should be held accountable for this defect and should pay for the necessary repairs.

  • 146,000 miles
I have a 2005 Altima 2.5S. I had the severe driver and passenger side floorboard rust problem. The rust is all the way to the floor mat. A big hole on the driver's side. I called the dealer brought the car for inspection and they send me to Nissan North America (800) Nissan-1 or 800-647-7261). They've referred me to with Nissan regional Consumer Affairs regarding the rusted out floorboards. I appreciated their "surprise" and "never heard of this before". when I told him it how bad the driver's and passenger side floor rust problem she said they are not doing anything right now with that because it's normal environmental problem. They will not help on the repair and send me to body shop. The replacement/fix of hold floorboard will cost $1700 including parts and labor. I looked my company 1998 Mazda truck, it has been driven a lot in muddy roads and snow, and no rust at all under the floorboard. I found there are a lot of complaints on the 2002-2006 Nissan Altima floorboard rust problem on google, and Nissan refused to take a recall for this most complaint problem. This is a design/manufacturing defect that Nissan refuses to acknowledge. Fyi: I served my car many times in Nissan dealership, including oil changes and whole car inspection. They never mentioned the floorboard rust problem at all to me until I found it. I do believe this is very dangerous problem for a car driven on the road, especially on the highway, and the floorboard can fall anytime. I really hope this can get an attention for everyone who has 02-06 Nissan Altima as well. Get the car repaired soon to reduce the potential fatality incident. I hope Nissan can take the responsibility for that repair. Thank you!
