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!

I purchased a new 2005 2.5S in May 04'...I've been having ignition/sensor problems for quite some time. The problem: When I try to crank the engine using the keys provided (at purchase) the car will hesitate (sounds like the engine is not getting enough fuel) I even thought it was a battery related issue and changed the battery...on several occasions I had to crank it nearly 5 times before it would start. I addressed my issues with the Nissan service department on many occasions but they will only attempt to fix the problem if/when it happens there. Recently, I was informed that a similar recall had taken place on the 2003-2004 models but that the 2005-2006 did not have the same issue...not!...I'm extremely disappointed in Nissan's approach to this problem. In fact, after an attempt to find out when the problem would be fixed I was informed that it would be several more weeks (December 10,2007).

The contact owned a 2005 Nissan Altima. The car intermittently happened on the freeway driving at 65 mph. This incident happened twice, once was in los angeles, and once in las vegas. The engine restarted after the incident about 45 minutes to 1 hour later. After it restartd it will drive for a couple of minutes and shut down again. According to the dealership, they repaired it twice. Already the first time they repaired vehicle it was a key problem, but he knew that it was not. The second time changed the electronic control module ( ECM). The vehicle is now ready to be taking back to the dealer the third time. The manufacturer said that he could not turn in the car, and they did not care.
