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!

Driver lost control of the vehicle and went into ongoing traffic and was T-boned by another vehicle. Both vehicles were going 45 miles per hour. No air bags deployed. The front airbags, nor the side airbags deployed. The passenger door came all the way over to the gear shift.

Reported to Nissan in early Sept 2014. Case number [xxx]. found while I was doing a brake job where car was elevated with car jack and I noticed the undercoating of the car "bubbling" downward and started knocking the loose material driver side floor board section approximately 8" X 12" completely rusted through where the underside of the floor mat was visible. Passenger side was ok. Seems water can work into some under-car seams, get trapped, lay, and begin to rust over time. Despite argument that a rusted through floorboard constitutes a safety issue, Nissan declined to participate in $480 repair citing rust warranty limited to 5 years, 60,000 miles. It was noted that local Nissan dealer was well familiar with the repair (their quote $637.81). Repair down at an infiniti car dealer body shop for $480.03. Found approximately half of body shops contacted respectfully declined to quote a "rust" issue. Information redacted pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6).

The driver and passanger floor boards are rusted. Like many other 2005 Nissan Altima's. the heat in the car also only runs warm when the vehicle is moving. If the vehicle is at a stop the heat blows cold.

Passenger floor board is rotted through, noticed it today when my passenger was in the car and his foot dipped down the hole that was created. Looked under the car and the only thing keeping the passengers foot from hitting the pavement is the carpet, this is unacceptable on a car, it is a safety hazard physically and it could lead to fatalities due to exhaust fumes entering the vehicle. I have researched this issue online and it seems to be a fairy common issue with 2002-2006 Nissan Altima. Took my car to the local mechanic and he said that this issue needs to be fixed soon as there is a chance that the carpet can catch on fire burning the enitre car.

While getting the brakes repaired, we noticed a huge area of rust/rot under the passenger side of the car. The rot area is approx 22 inches in length and about 10 inches across. Other then the high mileage, the car is in perfect condition. This issue makes me concerned for my safety and the safety of my passenger. In researching online, it looks like this is a known problem with Nissan Altima.

The contact owns a 2006 Nissan Altima. While the vehicle was being inspected, it was discovered that the front driver and passenger side floorboards were severely corroded. The vehicle was not diagnosed or repaired. The manufacturer was made aware of the failure. The failure mileage was 100,000.

Altima 4-cyl

  • 94,000 miles
During a routine brake inspection, my mechanic found that sections of my vehicle's floor approximately under the driver and passenger's feet are severely rusted. It is bad enough that the underside of the carpet/insulation is exposed in spots. I was shocked to discover this issue as the car has less than 100K miles and has no other rust or corrosion problems. After some searching on the internet, it is apparent that this is a very common problem with this particular make and model of vehicle and to my knowledge the manufacturer has not initiated a recall. At this point I am faced with an expensive repair on what is absolutely a safety hazard due to a poorly engineered and manufactured design.

Altima 4-cyl

  • 108,000 miles
As I was finding a spot, to place my floor jack, to replace the front brakes, I noticed a rust spot. So I went under the car and noticed the floor pans under the front seats are almost completely rotted out. The car isn't 10 years old yet and barely has over 100,000 miles on it. Within the next year or so it more than likely wont pass inspection. This is completely unacceptable.

Altima 6-cyl

Vehicle in for annual inspection - it did not pass secondary to extensive rust on driver and passenger side floor boards. Car is garage kept year round and not driven in winter (end of Oct - beginning of April). Car has never been in an accident and has been excellently maintained. No other issues whatsoever with vehicle. Quick search on internet and immediately saw many identical reports including video documentation. This is very upsetting and inexcusable for a car of this age driven in fair weather conditions. Nissan really needs to cover this defect.

I have a 2006 Nissan Altima - great condition, garage kept car - floor boards are rotted out on the driver and passenger side where a "plug" is suppose to be. Nissan dealership said that some of the cars got sealed and have no issues where other cars were not sealed and those ones are rusting away like mine. I have no other rust on this vehicle.

I will say I am a pa state inspection mechanic and this is not from neglect, I take great pride in my cars. And this is definitely a safety issue.. and should be recalled!!! General Motors is being held accountable for there issue! so should Nissan. Lets not let this get to where ppl are getting sick from carbon monoxide and falling asleep at the wheels.

Altima 4-cyl

  • 90,000 miles
My Nissan Altima VIN # included separately, has about 90,000 miles on it. It was bought February 2007 and has been owned by me since then (first and only owner). I performed my 90,000 mile servicing today and was notified by my mechanic that the floor boards on passenger side and driver side (undercarriage) are rusting and I can see a hole opening up there. He showed me while I was waiting for my car to get fixed at the shop. The rest of the undercarriage seemed fine. This indicates a manufacturing defect to me. I also would like to point out that this is a clear safety issue with the vehicle: Modern vehicles ought not to rot like so, and such a rot exposes the passenger and driver at great risk while operating the vehicle. I am getting extremely uncomfortable now operating this vehicle. It has served me well, and the engine/drivetrain has itself been trouble free. However, if the floor boards rot like this, I am unsure about the vehicle's overall structural integrity.

I took my car to get inspected and was told by my mechanic that both the drivers side and passenger side floor boards are rusting out. Because I know some people that can do the repair work for me I'm looking at about $1200 for the repair. Now that I've seen what some other people are being quoted I guess that price is fair. I already have exhaust coming through my floor and am concerned for my health at this point. Other then this issue my car is in perfect condition. My concern is if I don't fix this, my car in not I do not want to drive it and I could not sell it to anyone in good consciousness because I would knowingly be putting someone else in harms way. Nissan needs to take care of this huge engineering flaw and safety hazard.
