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 #1

Jul 262005

Altima 4-cyl

  • Automatic transmission
  • miles


The contact stated the fuel system and cluster module had to be replaced with less than 800 miles on the vehicle. There was a pinging noise coming from under the mid section. The vehicle was taken to the dealership, and they stated this noise was normal. A local mechanic determined it was a broken catalytic converter. Based on complaints on a website she felt that a clamp nut may be loose. This has not been addressed by the dealership. After 90 minutes in the vehicle the contact became dizzy by what she felt may be related to the exhaust system. The transmission jerked, and hesitated in low gears. The dealership has not been able to diagnose the problem with the transmission. The front windshield defroster partially defrosts the driver's side, but did not work at on the passenger's side. The vehicle has not been seen by the dealership for the defroster.
