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!

My gas guage read half, while turning car ran out of gas. Power steering and brakes failed when engine shut off. Fortunately I was turning into inside lane on 8 lane street because it took all 5 lines to safel roll to stop. After asking Nissan 700 to check fuel system senso 4/bolt 1 plug solid piece. Went to aaa $150 to check and determined guage not sensor. $600 to maybe repair part. Called Nissan 6 bolts 1 plug to replace guage module with 3rd party repaired used module from another state. Module has to be sent prior to 3rd party sending part. Internet horror stories. 6-60 day turn around and vehicle cannot be driven while part is out of car. Main reason: Speedometer and odometer are part of module. Module requires reprogramming to current vehicle mileage before moving. Nissan should carry parts in stock due to both dangerous safety and mileage issues related to failure of either module ar fuel sensor. I am pretty strong although 66 but youger, female or older folks in similar situations could end up in building, tree or anothe vehicle. Not knowing when car is die without warning is a dire safet issue.. recalls should be enforced by failure numbers, not %age of failures per model. 50% of a model that sold 200 is not as dangerous as 50% of 100,000 sold. The 2005 Altima ser was a very limited model of Altima but oem parts should be available until at least a majority of them are off the road when the relate to safety. Nissan seems to get away with out recalls for safety recalls, high frequency issues, service guaging and from what I hear known lemon problems. Why"??"

Rough idle. 3 years ago it did the same thing and I had the 0'2 sensors replaced and the crankshaft position sensor replaced. I drive it in town so in the 3 years I have put about 25,000 miles on it. The service engine soon light is on now and Nissan told me that I need to take it to a dealership and pay them to check out the engine and send Nissan the results and they "may" reimburse me for the cost of checking it out. I just replaced the spark plugs last week because I was told them needed replaced. It ran fine for a little while now back to same things. I have noticed that it leaks a little oil, about the size of a nickel over the course of 2-3 days. There is also oil round the crankcase. Wondering why might be. Thanks
