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 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!

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

  • 88,250 miles
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

  • 150,000 miles
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....

We are the second owner of the car, a family member was the first and bought it new from a Nissan dealership. One day in October 2014 my husband got in the passenger side and said it felt squishy. He stuck his hand under and could feel rot. We drove the 2.1 miles home and then he looked. That is when he discovered a hole at least 9 inches in the floor. I asked the previous owner if anything ever happened that would cause that and he said so it was never in an accident and the dealer who did all the maintenance work never mentioned seeing a rust spot. Now the hole is huge and is going fast. We have to use this vehicle because we can't afford a new one. Nissan says it is because it is an old car. My 1993 Honda civic (over 210,000 Wisconsin miles on it) and my husband's 2002 Nissan Sentra ser are older and they do not have rust underneath. We have to drive with a window open because the exhaust smell at a stop sign or when the wind is blowing against the passenger side of the car. We have 2 young kids that have to ride in this car as we no longer have the civic and the ser is small. Wish Nissan would own their mistake/design flaw and fix this for everyone. It would look good for them to take responsibility and set a "lead by example" initiative to all car manufacturers.

I already paid for rusted out passenger side floor pans and under. Almost $500. They told me it was a design flaw in certain models because of two holes you can visibly see under the car on both sides. Don't know why they designed it like that because what's happening is moisture goes up in there and flows over to the sides of the car under the doors and rusts. My car as not been run in the salt at all and I was told it wasn't necessarily salt but just water that settles and sits because of the design flaw, which has since been changed. I think they knew about this and are waiting for people to get rid of their cars so if they are ordered to do a recall, the numbers would be lower. I want reimbursement for this and the drivers side floor plan checked as well. My car is in excellent shape and had about 76,00 on it when I had the first side done. Thanks and I was denied inspection because of this, stating it was a safety issue! also we just moved back to nh and have been living in southern states because of my husbands job.

Altima 6-cyl

  • 126,000 miles
I recently purchased a 2005 Nissan Altima for my son who is going away to college. When seeing on the news about the rust issues with the Altima's I immediately went and checked underneath the car to discover that both the driver and passenger side floorboards are rusted through to the inside of the vehicle. The car has been properly maintained and in excellent condition otherwise. Due to the multiple issue in the 2002-2006 Nissan Altima I believe this needs to be a safety recall due to the possibility of exhaust fumes entering the vehicle. At the very least Nissan should provide a goodwill recall and stop trying to push the blame on other issues.

The bottom of my driver's side floor panel is rusted through to the ground. Underneath the carpet, just behind the gas pedal and brake pedal, the floor metal is completely rusted through. Nothing happened that immediately caused this issue. It seems to be a real problem. It could be very dangerous if my feet were to touch the street while driving and rip my foot off.
