When you start driving the vehicle from a cold start it drives and shifts perfect. As soon as it reaches operating temperature it will slam when shifting gears. After 5 minutes or so it will not move. Shut the vehicle off for 15 to 20 minutes and I shifts and drives fine for a few more minutes then the same problems happen again.

Transmission failure is causing van to stall. Can happen just traveling down highway. Happens as you try to pull into traffic. So sluggish you are afraid you will not make it through an intersection. Can happen just traveling down interstate. Frightening when in that situation with eighteen wheelers in your rear view mirror. Have taken to Nissan certified technicians and they have not been able to identify the problem. This has happened 3 times. Taken to dealership each time.

The three linear solenoids in the transmission fail, causing problems with vehicle shifting. Shifting from park to drive once engine is warm will cause a clunk in transmission. Also, downshift creates transmission surge.

Rattling noise coming from engine at start up. Goes away after a few seconds. The cause is faulty timing chain shoes and tensioner. Transmission jerking while driving.

I have to replace the transmission in my 2006 Nissan Quest 3.5 SE minivan. The transmission has air-flow problems, hard shift, acceleration problems, and gear shifting problems. While driving in the city, the transmission will hard-shift while decelerating and parking. While accelerating the transmission will automatically shift to a higher gear (making a racing sound/like rapidly accelerating) then jump (making a hard jolting knocking noise - especially while accelerating to highway speeds around 50-55-60mph). During driving, the transmission makes a sound similar to a railroad locomotive that has gotten louder over the past few weeks. Also, there has been an issue of slow acceleration while approaching 20mph. Beyond 20mph the acceleration is fine. This issue was temporary but worrying because there was a distinct smell of something overheating coming not from the engine itself, but from the underside of the vehicle. I turned off the engine and let it cool down for about 2 hours, after which the acceleration issue disappeared, but I fear it will return. I took it to a mechanic during which he plugged in the diagnostic computer. It diagnosed 10 codes - all transmission related. I am forced to replace the transmission at a cost of approximately $2,500.

My vehicle jumps at 35 miles per hour and makes a loud clicking noise from the timing chain.

Coming home from church with my family I was slowing down to make a turn at an intersection and van started jerking in the middle of the intersection and would not accelerate as I was crossing intersection. Serious safety issue for my family and others on the road. If Nissan wants to hold up their name and keep their customers, they need to recall these vehicles and repair them immediately before someone dies from their malfunctioning vehicles.

This is safety concern for me and my family. My Nissan Quest 2006 SE when it down shifts does not accelerate. This problem is a serious risk for me and my family when we are on the interstate and then exit and wait at the signal the car does not move and just revs up with almost zero acceleration. I want Nissan to take this car back and provide me a replacement.

As you start off from a stop the transmission jerks in the lower gears, the speed surges then goes back down and there is an infrequent knocking noise. The transmission also starts to gear down as you go down a decline at speeds of 45-50 mph.

While driving on highway the van started to shake while applying the brake and then there was no power as the gas was pressed. The gas was to the floor and the max speed was 50 mph. The more you drove the worst it got. I am only talking driving approximately 15-20 mile. When you first start out it is not as bad, but it is absolutely not safe to drive nor am I willing to drive it anymore. I have read articles on this and it certainly seems like a common problem. Lets get it together Nissan!!!!! I really want to know if going import is worth it. I have a 2001 GMC with over 175,000 with no problems.

Transmission failed causing vehicle to drop to neutral and loose acceleration above 20 mph. No power was available until the vehicle was slowed below 15 mph. Incident happened after turning into traffic and trying to accelerate to 45 mph. Traffic behind the vehicle had to brake quickly to avoid rear end collision.

The failure occurs while driving at either local traffic speeds or highway speeds. It is an intermittent problem. The failure is that, while braking, the vehicle accelerates on its own, as if the accelerator has been depressed for passing, causing the transmission to drop to a lower gear and the vehicle to lurch forward. The brake pedal must be vigorously depressed to counteract the acceleration. Experience has shown that, if the transmission is slipped into neutral and then returned to drive, the vehicle will return to normal until the next incident. The incidents have occurred six times over the past two years, the most recent being on Sunday, November 15, while trying to brake as I approached a dangerous curve on a mountain road. Please note that the accelerator was not obstructed by the floor mat or any other object during these incidents, nor was the accelerator pedal depressed at the same time as the brake pedal. I took the vehicle to eisenhauer Nissan on at their first appointment on November 17, 2009. I also called Nissan corporate headquarters to report the issue. The dealership was unable to diagnose the problem or correct it because the intermittent problem was not occurring at that moment. On November 17 Nissan regional representative owen welch responded to my second call to Nissan hq, but told me there was nothing Nissan could do for me. At my insistence he said he would follow up. Welch called again on November 23, 2009 to inform me that Nissan couldn't help and that he was closing my file. The vehicle has approximately 52,000 miles and is still under warranty.
