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 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!

Discovered rotted floor boards. Nissan has recalls for this issue and researched hundreds of complaints of this issue.

Vehicle exhibits serious rusting of floorboard on the passenger side front. The vehicle is in great condition otherwise (no visible rust on body panels) and the rest of the underbody is in great condition (minimal corrosion, as expected for vehicle of its age). Passenger side floorboard is noticeably soft, and rusted completely through the floor pan in one spot (you can put a finger through it if carpet is removed). This is unexpected as the floor pan is coated with a rubberized underbody protectant in this area. The floor pan must be replaced in this area, but Nissan only sells the entire floor pan for the vehicle, which is quite costly. I am disappointed because I have no evidence which indicates this issue is caused by any damage or neglect, it seems as if this is due to a coating failure or manufacturing defect.

The front floor pans have rustted away and part of the floor is missing due to rusting. Nissan is very aware of the problem and offered to install a floor fix at a cost of $700.

  • 109,000 miles
I took my car to a mechanic because I was smelling significant amounts of exhaust in the car cabin while driving and parked. The mechanic identified a rust hole in my exhaust just past the front catalytic converter, but more troubling was two huge holes in the floor boards on the driver and passenger side. Each rust hole is approximately 12 inches long X 4 inches wide and the padding an carpet can clearly be seen from underneath. Even after exhaust is fixed I am still at great risk of road debris and moisture entering the cabin from beneath the car. This car is just 10 years old and the rest of the body is in excellent condition with little to no rust. I live in a salt belt state but other cars of the same age don't seem to have this same problem. I've learned through media and web that this is a common problem with 2002 - 2006 Nissan Altima. I consider these holes to be a safety concern and manufacturer defect. I have filed a complaint with Nissan.

I have experienced many rust issues with my 2006 Nissan Altima. By far the worst is the risk of my feet going through the floormat due to rust of the floorboards. It is experienced on the driver's side, as well as a slight rust of the passengers side. I fear that I am in harm and can not afford the repair to make sure I am safe in my car. I have been using my car lightly for the last 4 years

I looked under my car today at a parking lot and found out that both passenger and driver side front floor board is rusting very heavily. I searched online and found many complaining about the same issue and same place in the car. My car has no rust anywhere else but only under the driver seat and front passenger seat. I am afraid that very soon it will develop into a hole in my car and I will be able to see the road under my feet from inside. This is very terrifying and I believe this is high risk safety issue. Since the same thing happen to many Altima owners, it is a design and manufacturing defect.

  • 130,000 miles
The part of the floor boards directly beneath where both the driver and the front seat passenger would normally place their feet has rusted through to the extent that only carpeting and insulation material prevents the feet from going through the floor to the ground. The local " carousel Nissan " dealership has taken photos and documented the damage but will assume no responsibility. The damage was noticed when a piece of the carpet or insulation was seen hanging under the car.

Drivers side floor pan rust through. It appears to be a common problem in the 2002 to 2006 Altima and maxima models. A recall should be performed. This problem is a danger, and very costly to repair.

  • 112,000 miles
Both my driver and passenger floorboards are completely rusted out. I have a 12" long hole on one of the sides. Nissan doesn't cover it because it's not a safety issue. It is not safe by any means. I can put my entire foot through the hole! my seat can become less stable, fumes can come in, who knows. The cost to fix it is more than the car is worth. No recall period, and they are aware of the problem. My sister has the same make/model/year and she was shocked to find out she has the exact same problem. Same spots, same rust. Also, both cars were garaged.
