Selected complaints filed with NHTSA by 2006 Nissan Altima owners, lightly cleaned up (personal details are redacted by NHTSA).
I have replaced the water pump, the belt, the thermostats, the rotors, the brakes, the fuel pump, the evap vent valve solenoid, the spark plugs, and fuel injectors and my car is STILL throwing the codes P-0462 and P-447. I've checked the wires and they are good. My car keeps misfiring and stalling now and my fuel pump doesn't have a fuel level sensor. The float bar is brand new as well as the fuel pump. And my dashboard speedometer is 10 miles off. I've tried everything and it's still throwing the same codes.
The fuel gauge stopped working. Fuel gauge shows full all the time. Error code is P0462. Mechanic replaced fuel pump module assembly and this did not fix the problem. Check engine light is on and will not go off and the code will not clear.
Vehicle is experiencing excessive oil consumption. I had to replace rack and pinion steering and vehicle is using excessive amounts of power steering fluid. I purchased both headlight assemblies due to not being able to align properly.
My dte said 180 miles, with almost a half tank of gas, car stopped on me on freeway, no warning light of low fuel. Car stopped and an accident occurred because of this problem. The dte or gas gauge does not read accurately. Please I need help
Tl* the contact owns a 2006 Nissan Altima. While driving various speeds, the engine suddenly vibrated, the check engine indicator illuminated, and the vehicle stalled. The vehicle was taken to an independent mechanic who diagnosed that the fuel pump was faulty. The fuel pump was replaced and the failure was remedied. Also, the fuel gauge would display inaccurate readings and was inoperable past the half fuel mark. The contact stated that the engine shook and vibrated due to low oil levels. The cause of the failures was not diagnosed. The manufacturer and local dealer were not notified. The failure mileage was 136,000.
On 5/23/19 my son was driving this car on the interstate when the car began to decelerate and completely stopped/shutdown on the highway. It's a blessing he was not injured/killed when this happened. The diagnostic check revealed a sensor that the fuel pump needed to be replaced, so after an expensive repair on 5/24/19.then on 5/25/19 while driving to work, the car began to do the exact same thing again and stopped on the highway. Nissan needs to address the issue with this car asap before someone gets seriously injured or killed!!!
Tl* the contact owns a 2006 Nissan Altima. The contact stated that the vehicle would not start without warning. The vehicle was towed to an independent mechanic where it was diagnosed that the fuel pump failed and needed to be replaced. The vehicle was repaired; however, the failure recurred 4,000 miles later. The vehicle was towed to an independent mechanic. The vehicle was repaired. The manufacturer was not made aware of the failure. The VIN was unknown. The approximate failure mileage was 86,000.
The car suddenly died in traffic and I couldn't get it to start. I had to put the car in neutral and push it out of the road. The gas gauge was reading that it had over a quarter tank of gas when it was actually empty. It caused my vehicle to run out of gas in traffic. This is extremely dangerous and could have caused me to get into a serious accident. No damage or injuries occurred in this particular incident, so I did not contact police.
My drivers seat is stuck reclined and it won't move anymore (parked).my drivers door won't unlock (parked). My engine continuously rattles and the car stalls (driving normal street or highway).the fuel gauge doesn't work accurately (parked driving on street highway or idiling). The brakes and rotors are constantly getting replaced and squeaked since the day I got the car ( stopping).
The gas gauge said half full but stalled out going down the highway. The car would not start had to call for someone to bring me gasoline I almost got hit by other cars behind me, this has happened several times. This car is vary unsafe I have two young ones I need to drive around.
