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!

2005 Nissan Altima Owner Comments

problem #2

Nov 052005

Altima 4-cyl

  • Automatic transmission
  • 15,000 miles


The car failed to start after owning the car for 13 months. The car acted as if it was flooded, cranking but not firing. To start the car I had to hold the gas pedal down until the car fired and started. The failure occurred after recently purchasing gasoline. We only use 2-3 different gas stations with good reputations. It seemed to happen the first cold spell of November 2005. The dealer said these circumstances shouldn't cause flooding and if the check engine light didn't come on they couldn't do anything to help us. The problem has not recurred but as a precaution, I ran the gas tank almost empty and put in a bottle of gas treatment. I also plan, if possible, on buying my gas from only one source from here on out.

The car failed to start only two weeks after buying it, and the problem has recurred. The car acts as if it's flooded, cranking but not firing. Both failures occurred after recently purchasing gasoline (the same gasoline retailer is used fairly consistently) and driving the car immediately home in cold, but not severely cold, temperatures. The dealer said these circumstances shouldn't cause flooding, but has been unable to find any problems and now refuses to research it further. Nissan Consumer Affairs has advised of a recall that may be applicable, but the dealer doesn't seem to be aware of it and I'm in the process of following up on this point.
