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 17-year-old daughter has a 2005 Nissan Altima. A week ago the car began shutting itself off while she is driving it. The codes said we needed to replace the crankshaft sensor and we did so. This did not stop the problem. On the way home from the auto parts store today her car stopped and she was almost rear-ended by a truck. After researching this problem on the internet it appears that Nissan Altima have a history of this sort of problem. Someone is going to get killed if this problem is not fixed.

Recently (07/10/10) my car just made a loud knocking noise blew a big smoke on the highway at 65mph--the fire men and police that showed up believe it threw a rod because it leaked oil everywhere, had the oil changed exactly 5 days prior.

2005 Altima - when moving forward after stopping, vehicle will jerk forward. I must immediately take my foot off the gas pedal. The occurs only in low gear, after a stop, and occurs 3 to 4 times a week.

The clutch pedal in my 2005 Nissan Altima is engaging but lately while driving, the clutch suddenly presses all the way to the floor while I attempt to shift gear. The pedal won't come back on its own, and shifting becomes difficult if not impossible. I almost caused an accident maneuvering my foot to unstick the pedal from the floor, while in traffic the other day. Then, it suddenly went back to its typical function and operated smoothly. I've experienced two of these occurrences within the past 3 days ; the car has been fine up to this point and has been well maintained ( 83,000 miles; one owner ).

  • 64,000 miles
The contact owns a 2005 Nissan Altima. The contact received a recall notice for NHTSA campaign id number 07V527000 (engine and engine cooling). She called the dealer and was informed that the recall repair would only involve reprogramming the computer, rather than repairing the crankshaft, which really needed to be replaced. The contact's concern was that the recall repair only stalled the failure instead of providing a remedy. On July 10, 2008, the vehicle completely shut down at a stop sign. The vehicle lost total power and no warning lights were illuminated. After waiting two minutes, the vehicle was able to be restarted. When the contact turned off the vehicle to pump gas, it would not restart. The vehicle would also surge occasionally. The current and failure mileages were approximately 64,000.

The contact owns a 2005 Nissan Altima. While driving 40mph, the driver engaged the brakes and the vehicle failed to stop. He attempted to engage the emergency brake and the vehicle continued to accelerate. The cruise control was not engaged. There were no warning indicator lights present during, before or after the crash occurred. The contact was unable to stop or gain control of the vehicle. The vehicle crashed into a tree and the vehicle was destroyed. The driver had back injuries in three places. A police report and photos are available. The police report indicated that they observed the driver attempting to stop for two hundred feet. After the vehicle was destroyed, the contact received a recall notice.

I was slowly pulling into a parking spot in front of my apartment building. As I reached the front of the spot (the end where the front of my car would be), my 2005 Nissan Altima bucked backward slightly, then suddenly accelerated. The car hit a tree, then continued forward until it stopped in the bedroom of my downstairs neighbor. My foot was on the brake the whole time. I am sure of this, as this is the second time in a year that this has happened to me. The first time, I was pulling into a parking spot in a parking garage, and the car accelerated into a concrete pole. Repairs to the auto body (only) were completed, but it seemed as though the engine was downshifting very hard. I had Nissan check it out, and was told there was nothing wrong. I am not nuts. I am not senile. I am not elderly (52). I have been driving for 34 yrs. And have had an excellent driving record (until now). The car was bought in December 2004, and in less than 18 months, I have had 2 almost identical accidents (same malfunction; same approach to the parking spot).

The owner had problems with the car since the day of purchase. In the middle of driving the check engine light comes on, the car stalls. There is no acceleration and the gas pedal does not work. The check engine light does not come on before the stalling begins. This happened three times. The first time this happened the owner thought it ran out of gas. There has never been an accident as a result. The vehicle has been into the repair shop three times, and the repair have been unsuccessful. The dealership replaced the accelerator position sensor, throttle chamber, and air volume learning procedure. The second time the accelerator position sensor was replaced again. The third time the accelerator position sensor and engine control module were replaced. Again, this did not appear to have repaired the problem, the owner is not confident with this vehicle. The dealership would not guarantee this would never happen again.

The caller's vehicle was accelerating from a stop light going 10 mph when it stalled. She could not get it started, and had to have it towed to dealer. The battery light and the brake light came on. When she called the manufacturer, she was told she could drive the vehicle. There was no other indication that this was going to happen. Dealer has vehicle now and will call her when they have check it. Manufacturer was contacted and will call her back.

Had the vehicle 3 months and transmission replaced. Noticed when driving the vehicle it accelerated, then when letting off the accelerator was pulling back like a rubber band effect. Currently, that the transmission been replaced when making a right turn it makes a clanking noise. Also, can feel every bump in the road.

Car just stops sometimes and it will not start. Consumer almost has to flood the engine before it starts. Dealer told consumer she needed to pump the gas 3 times before she started the car. She had vehicle in the repair shop because the car was idling very fast. They put a throttle chamber in it, then it started to do the same thing again. Dealer said it was unsafe because it was racing too high; they ordered a new part for the car. It is still doing the same thing. Updated 02/07/06.
