CarComplaints.com 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!
Ok, for a year or so, I've had chronic problems starting, about the first 2-3 starts then would not start at all but turn over. I would have to let it sit for about a hour each time and then it would finally start, so all my research said this vehicle had a unexplained phenomenon and that people had several things replaced and no improvement - then a crack in the block mixing coolant with oil. I fixed it with Therma Gasket and it has run great since, with intermittent starting problems.
