Notes: The 2005 Nissan Altima has two fairly significant problems with the floor pan rusting through & motor mounts breaking.

Altima owners report that up to a basketball-size hole develops under the floor mats where the floor pan metal rusts through. Average repair cost is over $1,000.

The broken motor mounts are less of a problem - they break at ~75,000 miles average & it's $400 to fix. Still, motor mounts should not break!

Vehicle has extensive rust under floorboards under driver's seat. I read about other Altima from this year having this problem and found the damage to my car by taking pictures with my cell phone under the car. The car was inspected at a Nissan dealer service center about six months ago for an unrelated issue, but I believe the car would have been up on a lift, and the Nissan service people did not advise me there was rust on the underside.

After performing an oil change I noticed the bottom of the floor pans were rusted on both the driver and passenger side. Upon further investigation there is a hole through the floor pan into the interior of the car. I asked Nissan to fix it outside of warranty due to this being a common issue among several other Nissan Altima between 2002 - 2007. Nissan of America said they would not pay to fix it. I am hoping you (NHTSA) can help in this matter.

Altima 4-cyl

  • 73,000 miles


I am the original owner of this vehicle. I found out on line, that there is an inferior design flaw which is extremely dangerous, that involves water accumulation and severe rusting clear thru both the inner and lower floor boards, on most 2002 to 2006 Nissan's. I checked my vehicle and found on the front passenger side, I have a 6 to 8 inch hole clear thru both the inner and lower floor boards. This condition is extremely hazardous in that in addition to someone possibly falling thru the hole, engine exhaust carbon monoxide fumes as well as water can enter the vehicle. There is also the possibility of an electrical short in the wiring that can cause a fire and result in death. In reading about this defect on line it stats that repairing this problem can cost thousands of dollars and Nissan knew of this rust problem, poor water drainage condition and will not issue a recall since this condition happened after the warranty period. The inter net articles stated that hundreds of complaints have already been filed and advised persons affected by this problem to contact the National Highway Traffic Safety Administration. I thank you and appreciate your prompt attention, in looking into this matter and await your response.

I am placing a complaint against Nissan motor company for faulty flooring in their Altima models. I tried to have our car a 2005 Nissan Altima inspected today but it failed do to rusting floors under the front passenger and driver feet section. This is a well known issue now that nbc news has broke the story about this problem in one of the broad cast. Nissan should not be let off the hook with this issue so I'm writing to you in hopes that will not happen. This company screwed up now people such as my family are left wondering how to pay for something that is no fault of their own. Please do something !!!

Car was in shop for front end suspension and technician pointed out rust holes under both the passenger and driver seats. This seems to be a defect in the manufacturing of the body, and was looking to see if there is a recall. Could cause potential dangerous situation if object in road is hit and comes up under the undercarriage.

While entering the vehicle my husband felt the passenger side floor collapses at which time he inspected the undercarriage of the vehicle and observed a large rusted through area under the passengers side. Due to the advance rust and rot of the passenger side floorboard of the vehicle I believe it is a safety concern due to possible personal injury as well as vapors could enter the passengers compartment through the compromised passengers side floorboard.

Altima 6-cyl

Passenger-side floorboard is experiencing the same pre-mature rust as many other similar Altima. Rust area is approximately 8 inches by 12 inches, and has already began crumbling away. Vehicle is otherwise in excellent condition and is well-maintained. This is clearly a manufacturing design flaw, and should be recalled by Nissan.

Altima 4-cyl

Excessive underbody rust in the passenger side footwell area. No sheetmetal remains in some areas, allowing for direct access to the passenger compartment and causing a safety concern for anyone seated there. This is a one-owner vehicle, which had auto armor underbody protectant applied at the time of purchase and is washed regularly, especially during salt months.

Friend in front passenger side of my Altima, cut her ankle when her foot went thru my passenger floor board..this is a rott issue that Nissan has ignored for years now... and its not a salt issue its a manufacture defect in the floor because of not being sealed good at factory...someone will eventually get hurt or killed, , as this rott will eventuality speed into frame and suspension.. Nissan is tryin to get out of a fix, just like the early pathfinder frame/shock tower rust issue.. where they now buy back the veh if it needs the recall... as always someone has to be killed before action is taken...Nissan says veh age, will eventually rust, , but this issue has been known for years now.... look on Nissan forums. Complaints for years now....
