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!

Forward is rusting underneath on the driver side and passenger side, have always had my car serviced when needed oil changes regularly washed regularly taken care of very well an all highway miles majority of the time. Keep having to repair the air conditioning system as well been spending lots of money lately I understand problems arise over time but the rust underneath the vehicle is a safety hazard considering I drive a lot of miles on the freeway. Found out this is a major problem happening with hundreds of Nissan Altima owners with these year models. I have been recommending the Nissan too many people I love this car and now I am afraid to get another one and I had planned on getting another one so if this issue isn't helped and taken care of I will look to purchase a different kind of car.
