On a visit to the Nissan dealership to have my headlight replaced, I was informed the floor on the passenger side was rotted/rotting and needed to be replaced. I've not had it repaired as of yet B/C I'm comparison shopping based on the price quoted by the dealership. I purchased the car in 2006, had the engine replaced due to failure in 2011, the radiator replaced in 2013 and now preparing to replace the floor panels. For a 10 year old car, which has been maintained and serviced regularly and garaged, rotting seems highly unusual and shouldn't be a normal occurrence for a car. I've never had a car require this many costly repairs, and especially never an issue with the engine or rotting. Please investigate.

I took my car in for an oil change and my mechanic indicated that I had a rusty driver's side floor board. He said that he was able to stick his hand through the bottom of my floorboard and touch my driver's seat. This had me very concerned due to the potential for the driver's seat to fall out of the car while I'm driving. My mechanic indicated that he's had the same problem with at least 2 other Nissan Altima. Based upon the number of complaints, it looks like this is a known issue and that Nissan will not do anything to compensate. It cost me $550 to fix due to the extent of the rust.

Discovered rust under the driver side floor. Upon further investigation discovered the entire floor plan had rusted off and was flaking off in pieces. This is a safety concern as hazardous gases can enter the cabin area. More over if I were to step in the correct place I could push the carpet out of the car. Numerous other people online have complained about this exact issue. Nissan should fix this with a recall.

One day I was driving and I heard something scraping on the bottom of my car, I pulled over to see that the bottom of my floor board was dragging on the floor. It just completely rusted out without warning and there is a huge hole. I have no rust on any part of my vehicle, it runs great, the body is in good condition it is garage kept, and I have a whole on my passenger side floor board. The only rust spot on the whole car! and how many complaints does it take before Nissan has to recall this? I have read over 50 complaints on this..... unacceptable.

1. the floor under the front passenger has rotted out making this car very unsafe. This is the most important one. The other ones I list because I am disappointed with the life of this car and because I have heard of multiple stories of the similar complaints. 2. the door handle broke off on the front driver side and on the passenger rear side. 3. gas cap will not close/open properly 4. trunk latch will not close. 5. moon/sun roof is off its hinge and will not work properly. 5. plastic part of the key broke not allowing it to attach to a key chain.

I took my car in to midas, burlington, MA for brake assistance, and while up on the lift the technician pointed out that the front passenger floor panel was very rusted. Warned not to use that spot when jacking up the car when changing a tire, etc. (mentally add this to $$ to spend this year...) had my car at ntb in cambridge, MA to check a front end rattle and the mechanic showed me the rust again. He is also a state safety inspector and wanted to let me know since it was rusted though it would not pass state inspection (due in August). Next stop was a local body shop and the estimate was $2K. Then saw so many complaints for the same problem for the Altima. I feel this is a known defect and should be paid for by Nissan. My car is well care for and maintained and is rotting!!

Pursuant to a non-related incident, my Nissan certified insurance adjuster warned me of the unusual rust formed holes on the drivers and passengers side floor boards. According to him, this is a very unusual rust issue that he has only noticed on older (2002-2003) Nissan Altima's. I have initiated my own research and have found that this is a wide-spread problem with Altima's, irrespective of mileage, where some have reported the problem at 50,000 and others at 160,000 miles. Despite the many complaints, Nissan has refused to issue a safety recall and has done nothing to help those who have been affected by the rust problem. Many, who had the problem, continued to drive without the knowledge thereof, until a mechanic or auto dealer informed them of the issue, as was the case with my Altima. As such, I can imagine that even more Altima drivers are affected, yet Nissan refuses to take responsibility. There must be a viable alternative to reach a resolution.
