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!

The contact stated vehicle stalled while driving on the interstate. There were no indicator lights on before the engine stalled. The engine made a metal grinding noise when it lost all power. He was able to get off the road without incident. The vehicle had to be towed to the dealership. They stated the cam shaft broke due to a material defect. The cam shaft will be replaced under warranty.

Car just stops sometimes and it will not start. Consumer almost has to flood the engine before it starts. Dealer told consumer she needed to pump the gas 3 times before she started the car. She had vehicle in the repair shop because the car was idling very fast. They put a throttle chamber in it, then it started to do the same thing again. Dealer said it was unsafe because it was racing too high; they ordered a new part for the car. It is still doing the same thing. Updated 02/07/06.

I bought the car on 9/20/04. On 10/3/04 I noticed that, the engine was leaking oil. Dipstick showed oil level was below low mark. Dealer inspection traced oil leak to the galley plug.
