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

Altima 6-cyl

  • Automatic transmission
  • 31,000 miles


On June 7, 2006 my wife was driving her 2005 Nissan Altima in a road construction area of I-10 in vidor, tx. There were concrete barriers on both sides of the interstate. She ran over a piece of tire in the middle of the lane and the car died. She was left stranded on the interstate. The car would not immediately restart, but started after a few minutes. The vidor police drove it off of the interstate but it was stuck in a higher gear. Upon inspection there is a electrical connection on the bottom of the transmission that came undone. There is a heat shield around the connection, but it does not protect the connection from being struck by road debris. If this is going to kill the car engine along with the power steering and brakes, then it should be better protected.

Altima 4-cyl

Our engine seized up while we were driving, oil light came on and the brake light came on as the car died but not before the car died, while we were out of town coming home from a business trip. The Nissan dealership said that the drain plug was missing. The oil light is supposed to come on no matter what when it gets low on oil, that is an electrical problem which is covered under the warranty that they pressured us into buying for $1500. Now they are not honoring any service agreements they made. They are in breach of contract. We have been paying for hotels, car rentals, food, gas, hitchhiking, everything..... we need to be reimbursed for everything and have Nissan take over payments for our car rental, loss of work, returning car, and getting a new one. We have spent five days now screwing with everyone except someone that will help. I have literally talked to 90 people or more since our car broke down. We want help right now, or we will sue trophy Nissan immediately.
