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!


definitely annoying

2005 Nissan Altima has defective crank sensor. The throttle stops working not allowing fuel to the engine therefore stalling the car even in motion. Nissan has redesigned replacements but are incorrectly redesigned. Even with warranty Nissan refuses to remedy leaving people without cars.

Altima 4-cyl

  • Automatic transmission
  • 2,950 miles
I purchased my vehicle 3 months ago. At approxiamately 2950 miles, my service engine soon light came on. Immediatly after that my car became sluggish and is having acceleration problems and feels like it is dragging. Brought to dealer service and they said the problem is with the throttle body and they have to order a replacement part. They released the car to me. I asked them if it were okay to drive, and if doing so would it make the problem worse, they advised no, it is okay to drive. I called in 3 days later to see if the part was recieved, they stated it was not, they claim the part is on back order.
