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!

2005 Nissan Altima with deceleration problems. Consumer states that the vehicle will decelerate from what ever speed to about 20 mph. He states that the dealer keeps saying bring it in while the vehicle is having the problem. The consumer stated the throttle chamber was replaced and the fuel injection serviced, however later in the month, the problem re-surfaced again. The vehicle always seemed to return to normal operation after the vehicle was turned off and turned back on again. The problem happened again on December 7th and 15th.

My 2005 Altima was failing to start normally. I took it to my local mechanic to find out why. After some searching my mechanic found the crankshaft sensor was faulty and had caused other fault codes to occur. The car has approx 56,000 miles on it and I was told this problem normally should not happen with this amount of miles. When the part was picked up by the mechanic, he was told that eight of these sensors were recently sold for this same problem. I also checked online and found some of the same complaints from consumers. One person suggested a recall should have been made for this problem. The part was $42 but after diagnostic testing and an oil change, my bill was almost $200! I have been happy with the Altima up to this point but feel there are several other Altima owners out there who have suffered this same problem. If that is the case, a recall should be issued. If a recall happens to be issued, then I feel I should be reimbursed for having to pay for fixing my vehicle.

I experienced an incident before that my car stalled but it restarted quickly. Then few weeks later my car stalled again but this time did not want to start up as quickly as before and my check engine soon light came on this time. As soon as it started up again I went straight to the dealership where I bought the car. On my way over there I was driving on the freeway and I felt my car loosing power and it jerked back. I was very afraid that my car would stall out while I was driving on the freeway. I went to the dealership and explain my situation but they were not able to help at that time because they were booked up. I left and went to auto zone and they performed a diagnostic test on my car. The reason my check engine light came on was due to malfunction of the crankshaft position sensor on my 2005 Nissan Altima. Next morning I went back to the dealership and they performed a diagnostic test too and concluded the same thing. They replaced it with a new crankshaft position sensor. The check engine light is off and the car runs smoother and has not yet stalled out.

Car stalling at in traffic, stop lights, and while driving. I was told to replace air filter and have fuel injector service. I did. Car began stalling again. I was told to have throttle body cleaned. I did. Engine light on. Hose put back on. Engine light on again. Was told there was code for idle valve but they didn't know how to address it. They reset computer. Car stalling again. Barely made it across intersection to get to dealership. Nissan replaced air filter, cleaned fuel injectors (again) and replaced crack shaft sensors. I just got car today. The car stalling while driving seems a bit dangerous.

: the contact stated the vehicle did not start on several occasions throughout the day. The electrical system was working fine, but the engine would not turn over. The vehicle was towed to a service dealer, where the dealer was unable to determine the problem, but stated that the cause was most likely due to the cold weather.

Purchased a 05 Altima in June of 2004. I have had nothing but problems. I took the car in at 19,000 and told them my car shakes and there is a ticking in the front end. Sounds like it is coming from the engine. You can feel the shaking in the seats, gear shift and steering wheel. Not to mention the shaking continues to knock my windows out of place. The shaking happens when your are sitting at a stop light and while driving. They told me that I would need to replace tires and alignment. I did the alignment. They then said that the ticking was normal and the shaking was normal. So being a young female I was took them for there word. I then was driving about 35 mph and the right front tire blew out. I was able to pull over, no one was hurt. Called Nissan said tires were not covered under warranty. So I went to an outside tire dealer to have replaced, was told rim was bent. Again called Nissan was told that was my problem. So I purchased a new set of rims. Just started to face the fact that I would have to deal with the shaking and noise. About 2 months ago returned to the dealer because along with the shaking and noise now there is a loud clunking on the right passenger side. Was told tires need to be replace, alignment and balance. Also get this right front passenger rim bent. Again! said it was the roads. Took to tire dealer. Rim was bent. He did his part, took it back to dealer. They have had my car more times in the last 2 months then I care to remind myself. But has been no fix to any of my issues. At closing of repair ticket was told ticking noise they did not know where it was coming from but they were pretty sure it was not the engine. The shaking was from a broke rack and pinion. So now that I am over my 36,000 mile warranty. I need to pay over $1300 to have repaired. I feel like this car is a lemon and I am now stuck. I am very upset with this lack of concern Nissan has with my issues. I need help getting my car repaired.

Altima 4-cyl

  • Automatic transmission

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.

Contact stated her car stopped on her while driving two-three times since mid August 2005. The car started shaking prior to stopping. The contact filed a complaint with the manufacturer. The problem has not been diagnosed. She wanted to file a complaint because she did not feel safe in the car.
