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!

My complaints I have with this car. My first is the floor board is staying soaked with water and molding, which is not good for people with allergies to mold as in this case, and the rusted floorboard problem. The second is with the oxygen sensor and catalytic converters.

Altima 4-cyl

  • 80,000 miles


There is no specific incident, but last summer (August 2014) I had new tires put on and the mechanic noticed that my floor board was beginning to rust out. I now know, through recent news, that it is not just my car, but most Nissan Altima models. I actually complained to them about it last summer and of course they did nothing. This should be a recall if mechanics and professionals are noticing that something is not right. I get regular car washes to prevent rust, as I live in northern Indiana and salt is the way we fight our snow problem. It is not safe for the floor board to rust out. If I were driving an older car I would expect this. However, this should not be happening to a 2006 model car.

I have a 2006 Nissan Altima that I took in for any inspection and the floor board on both the drive and passenger sides are rusting through to the point you can see carpet underneath. Looking around on the internet it became very obvious that I'm not the only one with this problem and a very big safety concern if the floor is just rusting out. I called Nissan and they basically told me too bad there is nothing they can do. They don't want to acknowledge the fact that this is a serious problem and a safety issue if the floor of the car is exposed to the ground. The car has spent the majority of its life in a garage so it must be from driving that they problem has occurred.

While my mechanic was checking my brakes and other things he noticed that the floor under the driver side and passenger side are fully rusted. When I got the call this morning I immediately went online to search for this. It seems like this is an ongoing issue and there is no recall for this (which im not surprise). I have spoken to a body shop since I work for an insurance company and they said this has been a problem with these cars. I also spoke to someone who works for Nissan and they confirmed that this is an ongoing issue.. I have never had any major issues with my car until this. It wont pass inspection which I have to do in a couple of months. I also have a friend who had the same car different year with the same issues and he just ended up getting rid of it. Im hoping to get this fix as soon as possible. Nissan seems to charge roughly $700 a side to get this problem taken care of. This is not fair to the consumer since its a flaw in their design. We should not be paying a dime to get this fix!!!

After a series of hard rains and wet driving conditions, I noticed a wet, musty smell in the cabin interior. After inspecting all door and window seals without finding any leaks, I inspected underneath the car and noticed that the floorpan area beneath both the driver and passenger seats were rusting through with open holes in both areas. This immediately struck me as a defect as the vehicle is otherwise rust-free. Upon researching, I discovered that this appears to be a common issue with 01-06 Nissan Altima. I contacted the dealer who acknowledged the issue. However, they noted that Nissan has not taken action to address this defect. They provided a rough estimate for repairs as they have referred other customers to body shops for repair (~$500-600 per side). Not only is this likely to damage the interior, but it would seem to be a likely safety hazard with the weakened floorpan. I have had my car at a Nissan dealership for routine inspections, and this issue was never noted on the inspection.

  • 100,360 miles
2006 Nissan Altima - car has been kept in very good condition - exterior is in flawless condition with no rust visible. Do not be fooled - the floor boards under the drivers side and passengers side are extremely rusted out. Took in car to Nissan dealership for service to replace water pump and was informed about rotted out floor boards. Despite multiple services at same location this was the first time this was mentioned to me. Conveniently after my 7 year / 100,000 warranty has expired. Something does not seem right - the outside of the car is in exceptional shape yet the underbody is completely corroded?

I am writing a complaint about rusted floor pans that seems to be a common problem amongst a lot of other "06" Nissan Altima owners. I found out about this issue after I recently had my oil changed and an employee at the body shop pointed out how bad my floor pans looked. There are literally huge holes in the flooring and if the carpet were ripped out, I would be able to see through them. In addition, I was told that the rust causes mold to form and it's dangerous to breathe that air in. I think Nissan should take responsibility and do a re-call since this seems to be happening to every owner who owns this vehicle.

The floorboards of the driver side have rusted through. This is a common complaint posted about numerous times online, with no response from Nissan. It seems that Altima from atleast 2003-2006 were effected. No recall has been placed that I have found, although many, many complaints and discussions about manufacturing defect.

Upon taking the car to the dealer for an oil change, the dealer informed me that the floorboards under the driver and front passenger seats are eaten away by rust and each side will cost $1000 to repair by welding a plate to it. It is so severe that the car will not pass inspection and be rejected for safety reasons, according to the dealer...
