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!

So besides the fact that my floor board on my drivers side has a huge hole in it, the crankshaft position sensor has cause me enough problems to where I believe Nissan should be responsible for fixing this issue. The vehicle idles rough, when accelerating it feels like the car is about to shut off, and the check engine light will not go off no matter how many times you change the sensor. I've had mine changed four times. I am actually sick of this vehicle now and will never buy another Nissan. To make it worse I can't take the car out of town because it will get hot then the clutch sticks to the floor. I have to lift it with my foot and it still won't engage, it loses all pressure. So driving long distance is out of the question. Someone needs to fix this before there is an accident. I almost got hit because I couldn't get my car to go into third gear. When I do get in an accident I will sue Nissan and anybody else who knew about these problems with this car and sat back and did nothing.

I am driving a 2005 Nissan Altima SE-R with approximately 140,000 miles on it. I was driving on a busy road and coming to a stop for a traffic light, probably at 5 to 10 mph. The engine shut off for no reason. I went to autozone and got the engine code and it is for can shaft position sensor. I browsed internet and this seems a common problem

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.

I brought my car to my personal mechanic for an oil change and a yearly inspection. While doing the inspection the mechanic took notice of the severe rusting of the front driver and front passenger floor boards. He said that it passed inspection and that something will have to be done about the rust damage soon before it gets worse and I end up putting my foot through it. I immediately called Nissan and they told me I live in a 4 season state and that it is normal do to salt erosion. I have had a garage kept vehicle and I am constantly cleaning the car during the winter because I know salt eats cars. Here I am 2 months later and I see the out cry of other Nissan Altima owners on the today show. How can they be getting away with this. I plan to get a new car within the next year so in order to sell this one I will have to spend the money to fix it because no used car buyer would want to buy it in this state. Why is Nissan not standing behind their vehicles? I will never buy another Nissan.

The vehicle would overheat causes the radiator to leak, while driving vehicle would stall for few minutes, vehicle would hard turn the starter and the engine light check would flash off and on while driving. Nissan dealership tends to try erase the code but has not fix the crankshaft position of the vehicle in June 2012.

Altima 4-cyl

I took my 2005 Nissan Altima into my local mechanic for an oil change and he informed me that my floor boards (on both sides)were so badly rusted out that he could see and feel my carpet from underneath. He also informed me that this was a safety issue and my car would not pass inspection. There is no rust on the body of my car so its disturbing to me that in a 2005 vehicle it can be that badly rusted underneath.

Recently while getting new tires installed at a tire shop, I was informed by the service technician that there was floor pan rust on both the driver and passenger side of my car. This rust couldn't of happened overnight since the rust is about to break through the carpet as if it were a 15-20 yr. Old car. The rust is located in the same spot on each side by the driver and passenger floor mats. On a shop lift you can see that the rust initially formed on each side where the drain holes were installed. At Nissan's request, I took my car (bought new) to the nearest Nissan for inspection. My complaint with Nissan corporate was that there should be a recall on floor pan rust as it is a safety concern I.e the seat can malfunction and also carbon dioxide could get inside the car. I also mentioned that I was aware any kind of rust was out of warranty and that the reason for the rust has nothing to do with living in high salt state. After extensive research, it became apparent that this has to be a design flaw by Nissan and that there are thousands of complaints on mainly 2nd gen. Altima having this adv. Floor pan rust in the exact same areas!! if the rust was sporadic, then salt would most likely be a cause, and if wet snowy shoes was the problem then there would be rust under the rear floor pans. As a result, as noted on the Nissan forum website, a more valid cause is design flaw, drain holes were improperly installed allowing water to congregate and rust to form. After Nissan investigated my file, they stated that there was nothing they could do to help. Not even partial reimbursement. I find this unbelievable and unacceptable.this 2nd generation Altima floor pan rust is so common that even my neighbor's 05 Altima has the same rust spots as well. What also disappoints me is that I have had all of my oil changes done by Nissan and rust was never mentioned once.

While driving the clutch pedal will loose all pressure and will fall to the floor. The vehicle must be shut off and left prior the pressure building back up in the clutch. This is extremely dangerous as the driver is unable to shift gears or put the vehicle in neutral. This is a notorious problem with all Nissan Altima SE-R with manual gear boxes. This problem will cause an accident and get someone killed.

While driving on the I-95 I began to approach slower traffic. As I proceeded to slow down, all the dash lights came on, my steering got stiff, and the car was completely off. When I pulled over and attempted to start the car again it hesitated but eventually it started. However, the most recent incident that has occur, the car no longer starts at all and only cranks but won't turn over.

The Nissan dealership performed a recall on our vehicle on 06/10/2008 for the R0712 ECM program recall and the P5216 recall. Since that work, the service engine soon light has been on in the vehicle which reported a valve problem. Prior to this work being done, the light did not go on. We have had the car serviced 4 times for the the repair of the valve, and now a full diagnosis needs to be done to figure out why the valve keeps shorting out. It appears it is going to be something electrical or with the computer.

I was driving my 2005 Nissan Altima SE-R 6 speed manual when the clutch just sank to the floor I was in rush hour traffic and head could not go at the light. After a couple of times the clutch went back to normal pressure. About 30 minutes later it happened again, but the clutch never went back to pressure I have been reading forums online, and this happens to be a problem for most 02-06 Nissan Altima owners with manuals. Nissan needs to own up to the problem and fix this safety hazard.

I received a notice from you guys after the fact. My car dealership(service guy). I went to the repair shop for something else and that's how I found out of the recall. Something could've happen to me or someone else while driving this car without warning. They did reprogram the car module. But I don't think that's the issue the car is still driving as it did before and I hope I did not purchase one of your many cars I've heard of as a lemon. I really need to know my next steps in looking into getting a upgrade on this vehicle because I really love these Altima. I don't want to have to go to a dealership and go through the whole process again. Please let me know if I can take this car to a Nissan dealership to switch it out I only have 34,399 miles on this car. This was the second recall on this car and I only had this car a year I traded in my galant 01 and that only had 59,732 miles on it so I'm not hard on cars I take care of things. My safety is very important to me I don't want to hurt no one and I don't want no one to hurt me or get killed. I'm bringing this matter to your attention first asking you to also don't put my safety or nobody else in jeopardy. Please respond back to me so this matter can be resolved quickly. Thank you, alfreda thomas

I purchased a 2005 Nissan Altima in 2006, and in 2007 I started having trouble with the car just stopping when I was driving, this has happened several times, thank god I have not had any serious injuries because of this. My mechanic stated that this was a problem with something dealing with my engine computer resulting in circuit malfunction with my crankshaft, and engine speed sensor, the problem with the crankshaft resulted from me having to restart my car after just stopping on me. I don't feel like I should have to be responsible for repairs if there has been a recall on the very part of this vechicle that has resulted and lead up to the problem that I am having at this time. I have mentioned this to Nissan and explained the problem that I am having, and seems to me that the company is just trying to get out of their responsibility of the mistake that was made when building this vehicle. The recall letter clearly states that if the dealer fails, or is unable to make the necessary repairs free of charge, I may contact the national consumeraffairs department. Thank you for you time in this matter, and hope that it can be resolved in a timely matter.
