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!

I took my vehicle in for an oil change and the garage informed me that the floor board on the driver side was rusted out so bad that you could touch the carpet from the bottom. Also the passenger side was rusted with a hole but not as big as the driver side. I am not sure why Nissan has not issued a recall for this being there are hundreds of complaints for this. This problem is a safety issue considering it will not pass a safety inspection.

The floor boards on both the driver and passenger have rooted out almost completely on my 2006 Nissan Altima. I have noticed this a about a year ago and it has got increasingly worse since. I can push the carpet up from under the vehicle and feel very unsafe. I am careful not to put weight on the floors while entering the vehicle for fear I am going to put my foot through the floor. This is a very common issue due to a flawed design in the drain system. The floorboards hold water which may accumulate through the door while raining and salt and water from the under side. Please issue a recall and make Nissan fix these vehicles that could stay on the road for many more years. My car has 109K miles on it and is in very good shape and runs very well. I don't want to have to do this job myself or pay 1,000 to get it fixed.

I discovered both floor pan/boards under the drivers and passengers side of the vehicle was rusted through. I had been tracking the problem for about 4 years, I finally had to purchase both new floor pans $171 each and have them replaced by a professional repair shop after oi removed the interior and reinstalled it once the repair was accomplished at a price of $799,00. The only thing holding the floor in place prior to repair was the sound proofing under the carpet. The poor relief or draining of water under the vehicle was a direct result of this vehicles problem.

Altima 6-cyl

  • 55,823 miles
Just wanted to add my complaint about my 2006 Nissan Altima which had severe rust under both sides of car under the seats. At the time it was noticed the car had 55823 miles and was serviced at the same dealership for the previous 4 years and just 3 months prior being noticed. Although I had to pay said dealership to repair after fighting with Nissan and dealership for 3 months. Just wanted to add my complaint after seeing article on tv news. Although car was 7 yrs. Old it should not have rusted with 55000 miles on it. Nissan motors would not pay cost for repair.($740). I know Nissan is big Corp. But either they or dealership should be held accountable. Big business wins again.

I took my 2006 Nissan Altima to the dealer and a private auto mechanic to have it looked over before my extended warranty expired. The private mechanic showed me underneath the vehicle while it was on the lift and the entire drivers side floor is rusted almost through. Both Nissan and the extended warranty company said this repair would not be covered, in fact in the extended warranty policy it explicitly excludes the floor of the vehicle. I don't know how long it will be until the vehicle is unsafe to drive as my feet will eventually go through the floor.

Huge rust under the driver's seat on the underside of the car. Also starting under the passenger front seat. Floorpan is rusting out so badly I fear my foot will fall through. This is not safe. Car has not other rust and well cared for. There is a problem here. I drove my last car for 21 years with not rust problems anywhere and I still live in the same area. This cannot be because of age or snow and salt. This appears to be a defect in the metal or design.

Severe rusting & rotting of the driver and passenger front floor boards. Vehicle is otherwise in excellent condition and well-maintained. This body section appears to be defective and could be a safety issue if debris were to impact the weakened section at speed. Please take this complaint, and all the others like it, and have Nissan issue a recall!

On or about the above date, we took the above vehicle in for routine scheduled maintenance. The dealer contacted us stating that they noticed that the driver and passenger side floor boards had rusted through. This was rather a surprise, they had not noticed it before...we have taken it to the same dealer for maintenance since we purchased it from them. The technician advised that they had seen this on this year and type vehicle before, "they have been known to rust out". he also stated that we should get it repaired as soon as possible. Due to our concern for safety, we had an autobody shop repair it.

There is rust and holes that have developed under the drivers side of the car. I understand that this is happening to alot of Nissan all over the us. I also heard that because there aren't any injuries or fatalities that they haven't put a recall on this defect of the car. Is that what it will take?

I found out today at a routine oil change that I have significant rust damage to the floor board under my car. At this time it is my understanding that Nissan is doing nothing in regards to the many complaints of the same issue. It appears that the first layer has eroded away and the second layer is already rusted and peeling. It is unknown how long it will take to erode through the to the interior of the vehicle. I have two young children and no longer feel safe in this car.
