CarComplaints.com 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!
Mechanic replaced crankshaft position sensor, since then engine idle 1000 rpms over normal idle speed. Also does a pulsating when decreasing speed between 50-45 mph.
The car is getting about 9.5 mpg and now the idling is fluctuating from 300-900 rpms seemingly trying to cut off. I now am having to change all of the gaskets and the oxygen sensors since the check engine light came on seemingly in unison. I am not giving up on Nissan yet though!
Its actually a Nissan Almera which is not listed on this site.
1. When I turn the key to start, nothing happens. I have to put my foot on the accelerator to start the vehicle.
2. On most occasions when the car starts the revs go up to 3500 rpm then comes down to 2000rpm and starts to automatically constantly fluctuate between 2000 and 3000 rpm. This can go on for over an hour of driving which makes driving in traffic terrible. When in neutral, it continues to do this. I was told it is a faulty MAF sensor which I replaced but the problem still persists.
Since I bought the car it's been having idling problems. Mechanics say it's the mount but I feel it's been long before that. I change the spark plugs and crank sensor and it did a big improvement but still has issues.
