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!

2005 Nissan Altima with entire under carriage rusting and rusted through certain areas. I change my own oil so it was not discovered until I brought it into a Nissan dealership for a timing belt repair in may '10 while on the lift the Nissan tech pointed out the problem. He even admitted that this has been a problem/defect in this particular model/year. We took our complaint to Nissan and filed a claim (claim #[xxx]). they informed us that since our warranty was expired there was nothing that they were going to do. Even though the rust was not discovered until '10 it was there all along during the warranty time. This is a garage kept car and is in very good condition. There are no other rust problems except for the under carriage. I have read numerous complaints about this problem and hope to have support from outside Agency to make Nissan make good on it's quality of car. We did not spend our hard earned $33,000 on a fred flinstone car!!! we are willing to summit pictures and continue our mission until justice is done. This is a huge safety concern that Nissan should address. Without the knowledge of this problem one could be injured severely.

The paint on my 2005 Nissan Altima which is pearl white is peeling off on each side of the hood. My car is still under warranty 89,000 miles and Nissan will not do anything to help me with this defect. I was told that the NHTSA are great people and maybe they could help me.

Took my car in to be inspected (pa inspection). Floor pan on my 2005 Altima is completely rusted through on the passenger side of the vehicle. Needs to have floor pan replaced. This car has very low mileage, is clean and garage kept. Checked the internet, and noticed quite a few complaints about rust on the passenger and drive side. Nothing else is showing rust. How can one part completely rust out and the remaining part of the car has none at all?? apparently there is a defect that is holding water/moisture and causing the rust. The car does not have any mechanical issue - basically like new. However, totally rusted out in one spot.

The trunk of the vehicle, which in my opinion is designed poorly and does not have a secure way to stay upright, has fallen down and hit me on the head while I was leaning over the trunk to collect packages or bags, on more than one occasion due to wind.

I would like to report a situation I had with my leased 2005 Altima that could be a serious problem for drivers and I think you should look into for a possible call back. Seven (7) of the clips ( part 01553-09321) came off the car while driving, causing the lower engine cover to fall down and hanging by the remaining clips. Not knowing the problem, I was startled and had to quickly pull over to see what the problem was. I had to tape the lower engine cover with duct tape in order to be able to drive the car. The cover is being held on by clips rather than bolts. If bolts or screws were in it, it would not have happened. I have been told that the service department that they replaces a lot of these clips. It seems to me that if you are replacing a lot of clips, they are not doing the job. If lower engine cover falls down, it could cause a major accident if the car is going at a high speed. I think it is incumbent on you to look into this matter, before there is a major accident. I am now very nervous about using the car, because if it happened once, it could happen again. The dealer is staten island Nissan 222 parkinson ave, staten island, New York 10305 (718) 447-3878. I spoke to Nissan and they claim that there was a scrape on the bottom and that it was my fault that it happened. If clips can pop that easy, there is definitely something wrong. It could not happen if they used bolts.

Where do I begin. First test drive, we stopped to put gas in vehicle. Then on start up it would not start. Had to call dealer for a jump start, twice. Then 2nd week my driver side exterior roof molding kept popping off. After the 3rd time, it was warped. Took to cardinale Nissan in seaside ca, and they ordered the wrong part. Then after driving around with some bright blue tape all the way down my car, they then suggested that they had to follow a bulletin from Nissan where they just placed new clips and lots of glue. They didn't replace the molding. A few months later it kept popping off again. Took car back and then they wanted to charge me to fix the problem they never did! after arguing they agreed to replace with new molding. I waited 2 weeks for part to come in, took car back 4th time. When I picked it up, they had once again, just put new clips and even more glue. They didn't replace molding again. Was told to wait 48 hours for glue to dry, so now I got to drive around with neon green tape on my car. Two days later, took it back and it was still lifting. They finally agreed to replace the molding. I have to wait another 48 hours with a new strip of green tape.

An update to a previously reported problem, which may help other car owners in determining a suspected problem. I have a 2005 Nissan Altima 3.5 sl. Last summer I was having problems with the car's handling at highway speeds. I had the car aligned, replaced all 4 tires, one by one and was still having with the car-which was shaking at speeds over 60 mph. I took it to the dealer again and they determined that the shaking was like a turbulence effect. The spoiler under the car was not allowing the wind to flow through properly, which was causing the shaking effect at highway speeds. The dealer replaced the spoiler with the 2.5 model's spoiler. This seems to have solved the problem. This car is a lighter car and the wind does have an effect on it when driving at higher speeds. The tires which are a Continental brand are probably not the correct tires for the car due to road force issues and not the proper speed rating for this model either. I will probably replace those with a better model and high speed rating once they start to wear down.
