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!

Altima 4-cyl Diesel

  • 77,000 miles


Upon a routine oil change my mechanic noticed the huge amount of rust under my driver and passenger floorboards. The carpet inside can be seen. Upon researching this problem I found numerous complaints with this same problem where Nissan is doing nothing about it. This is a low mileage well maintained vehicle. Im shocked at the amount of rust in these areas. Normal wear and tear would not cause this. Nissan should be recalling these cars.

Discovered rust under the driver's side, sheet metal is rusted out. Will need replaced. Unacceptable for a garage kept and well maintained vehicle that is only 7 years old!

Floor boards rusted through under driver and from passenger seats (foot rest area) because of poor metal coating and poor drainage design. Rest of the car is perfectly fine. Car has very low mileage and no accidents. Having hole by the floor rest area is a safety hazard. When rust started car was still under warranty but dealer refused to check, now floor panels must be completely replaced. Reading other similar complains all over the web and personally knowing 3 other Altima owners with exact same issue, I am very surprised that no action take so far.

Altima 4-cyl

The floor pan on my 2006 Nissan Altima 2.5 sl is rusting and corroded underneath the passenger seat and could present a safety issue. I contacted my local Nissan dealership and they were unable to assist me because the car is out of factory warranty. I find it hard to believe that a car 6+ years old would be rusting that bad especially given that the car has been kept in my garage and well maintained. I have searched on the internet and found numerous 2002-2006 Nissan Altima owners that have the same issue. I believe this is a defect and Nissan should issue a recall and repair these vehicles.

Altima 4-cyl

  • 130,000 miles
I took my car in for routine maintenance and my mechanic noticed the floor board on the passenger side was rotted. The rotting is approximately 12' X 6' the front seat will eventually fall out of the car if it's not repaired soon and/or mold will start developing soon posing a serious health issue. Upon research of this issue, I found this is a common defect on Altima's from 2002-2006.

The driver's side floor board has rusted through, which is very unusual for a vehicle of this age. According to various data online, the metal was not properly treated to prevent rust before installation. We are requesting that Nissan repair the rust at no charge to us.

Altima 4-cyl

  • 84,000 miles
My Nissan had extensive rust damage to the left and right front floor pans. It was taken to a Nissan dealer. Nissan will not repair because car is over 80,000 miles. This damage did not happen in the last 4,000 miles. Filed a claim with Nissan, again they will not repair. I was told to send a letter to Nissan North America Consumer Affairs. I was told by a body shop that it looks like the car was not sealed properly right from the manufacturer and water entered through the floor pan seams and the plug under the car.

The contact owns a 2006 Nissan Altima. The contact stated that the floor boards on both sides of the vehicle were completely corroded. The manufacturer was made aware of the failure who did not offer any assistance since the vehicle had surpassed the warranty mileage and the contact was the second owner. The vehicle was taken to several independent mechanics who stated a patch and repair with welding of a new floor board would be required. The vehicle was not repaired. The failure and current mileage was 142,000.

  • 60,000 miles
Front passenger floorboard rusted through, with a hole approximately 4"X8" in size. I bought the car when it was a year old and it has been meticulously maintained and still looks new inside and out. It is undercoated, and has no other corresponding corrosion. The rust is not coming from underneath, nor from a leak in the interior (the carpets are dry), but from between the two sheet metal parts that make up the floor. As a mechanic, I know there is no form of maintenance that could have prevented this rust from occurring. As a safety issue, my state will fail this car for inspection because exhaust fumes can enter the interior of the car without the occupants knowledge, and the floor could continue rusting, compromising the integrity of the front passenger seat mountings.

Around 6 months after the lease of my vehicle I noticed a hole on the floor, and any time I contacted the dealership and told them about the problem nothing was ever done. I was told that it was my car. Therefore, my problem. It has been almost a year and a half and the hole has gotten bigger. I may one day die in that car due to the heel of my shoe getting stuck in that hole, because I may not be able to get my foot out from it in time to brake, or my foot may get caught in there.
