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 safety and durability of liquid filled engine mounts needs to be examined. They are a total and utter failure. The manufacturers know this, but are making the consumer pay for replacement for premature failures and related damages. This is why you have engine run always. The electronics aren't meant for this much vibrations. With a solid, or even semi-solid mount, the frame absorbs some of this energy. Best replacement mounts should be a semi-solid, honey comb neoprene core, with cable reinforcement.

My wife's 2005 Nissan Altima was in for a routine oil change when we discovered the passenger side floor pan is rusted through to the interior carpeting. There's not a mark on the car otherwise and my wife loves her car. She purchased it new from the dealership. I called the original dealer. He has never heard of it and wants to see it for himself. I find that hard to believe with so much noise on the internet regarding this safety defect.
