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 4-cyl

Now, when I picked it up from that dealer, my car would not start. I cranked it 4 times and it would not turn over. Nissan tech who worked on my car, raised his hands up and said "I just fixed the molding". and walked away. My car never had that issue before. Just when I picked it up that from the dealer. Another more helpful tech came and immediately told me he needed to reprogram my keys"!"! he did it and said bring in all the rest next week and I'll reprogram. I went home and none of my keys worked. I had to tow it into my local dealer "my Nissan" in salinas ca and they told me they could reprogram all my keys for only $50. 2 hours later they said they couldn't figure the program as my car wasn't recognizing any codes they were using. So 5 days later, its' still at the dealers and they had to order a new eom and internal antennae. First they wanted me to pay for it. I have extended warranty and have followed all maintenance requirements so I refused. After 3 days, they agreed to cover the unit but not the antennae and finally approved for a rental car. I have yet to hear from them on my car. They offer no explanation on how or why it happened.
