Notes: The 2006 Nissan Altima has a trend of engine problems, both in our data & definitely in the NHTSA's complaint data as well.

Excessive oil consumption is the main problem reported by owners. Nissan did a recall back in 2006 for oil consumption due to bad piston rings, but many owners report to us that the recall didn't fix the problem.

The dealer only had to check the oil consumption rate. Typically 1 qt per 1,000 miles is "acceptable" per OEM standards ... that's a lot of oil!

problem #157

  • miles


Extreme rust and corrosion of the driver's side floor panel and frame. Rusted area is about 3' X 1'. rust has exposed the insulation under the carpet; there is no metal remaining in a 4" X 6" area. Metal around this is very thin. I am concerned that too much pressure from my foot will cause larger area to collapse. Estimate to repair at a body shop is about $1,400. I have driven many cars longer than this and have never had a frame or underside rust like this. It is surely a defect in manufacturing and a possible safety issue if my feet go through the hole or a piece of road debris penetrates the carpet.

It has recently come to my attention that the floor pans of my car have rusted through to the point where my foot could go through the floor pan. After taking my car to get a safety inspection in the commonwealth of Virginia, my car has failed inspection and cannot pass until these hazardous holes are fixed on both driver and passenger side. This is a manufacturing issue due to the number of complaints that have been filed in regards to this matter. Owners of these vehicles should not be held responsible of this issue. Again, this is a reoccurring issue among Nissan Altima, specifically the years 2002-2006. I am now required to pay at least $500 to repair an issue that is out of my control. There is no way that I can stop rust from occurring. These cars should not be allowed to be driven because exhaust fumes can enter the vehicle as well as a foot going through the holes. It is unethical of Nissan to allow these vehicles to still be driven knowing that this is a reoccurring issue.

The floorboards are rusted out below the front driver and front passenger feet. My mechanic told me it won't be long before I'll have two large holes. Surface rust or wheel arch rust is one thing, but structural rotting for a car that's 10 years old is excessive.

The floor boards under the front driver and passenger seats are prematurely rotting. Each side has a huge hole approximately 5 inches across and 8-12 inches long and the holes continues to enlarge. This particular complaint has been made by hundreds of times by others. It is a safety issue and Nissan should do something to repair the vehicles! date listed below is when I first discovered it after a mechanic brought it to my attention while the car was up on a lift.

During a recent oil change, my mechanic brought to my attention that the front seat floor boards were rusting on both the drivers and passenger sides. The rusting areas look almost identical. I researched this on the internet to find that this is a common problem with 2002-2006 Nissan Altima. There apparently have been a few class action lawsuits filed and several television reports on the matter. I have called Nissan; however, they claim it is not a defect. I discussed with a neighbor recently who also owns a Nissan Altima built in that timeframe and found out that he too recently discovered the rusting floor board issue. Nissan told me that I lived in a salt state and did not know how I maintained my vehicle; however, given the hundreds and probably thousands of complaints filed, it is nearly impossible for this issue to be due to owner negligence. My hope was that my 15 year old daughter would be able to have this car once she gets her license, but now I'm faced with spending thousands to either fix the issue (which may not be fixable given that rust areas grow) or to buy another vehicle. There is currently a hole through my floor board and it is a safety concern to me, especially if my daughter is behind the wheel.

Both floor panels rusted out. Major safety issue. Cost more to fix than what the car is worth. I still owe $4000 on the car and it's now worth nothing. Nissan doing nothing about it.

The floorboards have rusted right through to the outside. This should not happen with normal wear. We have just been alerted to this by the mechanic and it is so advanced he advises we don't use the car! repairing it is probably more than the car is worth!

I have owned a 2006 Nissan Altima for the last 6 years that has 126,000 miles on it. During a recent inspection the mechanic found severe rusting and a significant hole in the driver's side floor pan; you could see the interior carpet from underneath the car. It looks like the floor has been eroding for quite some time. After searching for this issue online, I learned that this is a common problem with Nissan Altima from 2002 to 2006 relating to a faulty design in a drain (those were a Nissan reps own words). I¿M frustrated that there were no recalls or communications regarding this known issue. I¿D hope that Nissan can be compelled to be transparent and forthcoming with known issues which may be a risk to customers¿ safety.

It seems like this is a widespread problem with older Altima. Apparently the driver and passenger side forms a rust problem which can cause one to feel unsafe driving the car. The image I attached shows the floorboard not only rusting but coming off, and I can push on the bottom of the carpet from the bottom of my car. Nissan knew of this problem since 2008 and has not offered any obvious statements nor recalls. This is potentially dangerous and is an expensive repair (for both side floorboard replacement, it can cost 3000)
