Warning lights "slip", "tcs off" and "service engine soon" would intermittently remain on well past ignition -- usually after the engine had struggled to start. Dashboard "tcs on" switch did nothing to remedy this. Sometimes, even when the van was being driven at 25 to 55mph, these lights would suddenly pop on and the engine would stall out, depriving me of most of my steering and braking capabilities with traffic right behind me. In my area, the main highway is heavily traveled, full of curves and often narrows to 2 lanes with very limited shoulders. The engine dying unexpectedly on this road is a safety hazard not only to everyone in my vehicle but to oncoming traffic as well. I am frequently followed by fully-loaded logging trucks and semis, whose drivers would find it extremely difficult (if not impossible) to avoid hitting me, especially if I were in a spot where I could not coast all the way off the road. After reading numerous online complaints of others having the same engine problem, I wrote to Nissan reporting the danger, suggesting a recall. (file #7197243) they refused to cover repair because my warranty had expired. Told me to take my Quest to a dealership, who wanted $104 just to hook up their diagnostic equipment, plus the actual repair costs. The problem -- a faulty camshaft sensor -- was subsequently fixed by a local shop. The mechanic there told me that the mechanics' "crystal ball" hotline was reporting frequent failures of this component -- in addition to a tsb Nissan put out on the problem. (so, they are aware!) given the importance of this sensor for safe operation of their engines, shouldn't the company address the high failure rate of the ones installed in their vehicles, regardless of mileage? I hope you will look into this before lives are lost as a result of Nissan's refusal to acknowledge and deal with this safety issue.

There are major problems with the shifter/transmission on my 2004 Nissan Quest van. The problems started a few years ago when parked on a slight incline and the van wouldn't shift into reverse. I called the dealership and they advised me to pull forcefully on the shifter to make it shift. It did shift but this has continued to be a common problem. After about a year of dealing with this, the shifter started to not engage in the correct position indicated on the dash and I would have to play around with it to get it to engage in the correct gear (it looked like it was in drive according to the base of the shifter, but was actually still in neutral). There were other symptoms such as having to push the shifter firmly in to park to remove the key. Fast forward to today and I finally discovered what has been happening. I went to shift in reverse on an incline and had to very forcefully pull the shifter into reverse. After doing so, the dash and the base of the shifter are mismatched by a whole gear.

Transmission held car to 20mhp then after shifting back and fort it goes back to normal. Engine dies here and there, when break pedal is pressed car steering wheel shakes. This almost cause an accident. Dealer took this car many time and they tell me. That they can't duplicate the noise. Researching online I found many complaints about this car and most of them says that the transmission brain is faulty.

- Fall River , MA, USA

The contact owns a 2004 Nissan Quest. While driving approximately 45 mph on normal road conditions, the contact depressed the accelerator pedal followed by an extremely low power response. The RPM's suddenly increased. The contact experienced erratic shifting between gears and hesitation. The failure recurred several times and the vehicle was taken to the dealer; however, they could not duplicate the failure.

The failure mileage was 28,000 and current mileage was 31,000.

I currently lease a 2004 Nissan Quest. My lease is up in August 2008 and my transmission broken down on me in January 2008 @ 63,700 miles. The warranty on the vehicle covers 5 years or 60,000 miles. As you can see, I am over the miles by 3,700 but the product should not have broken down at only 4 years of age. Emma lancaster (customer service rep. North american) and the Nissan corporation were not helpful in solving this problem of replacing the transmission at no cost to me. After waiting 2 weeks for emma to return my call with a status of the situation, she informed me that I must supply proof that I had all necessary maintenance done on my vehicle. I then submitted receipts from independent station owners indicating that all necessary maintenance was performed. After waiting yet another week for an answer from emma and Nissan, emma informed me that Nissan would not pay to replace my vehicle because I did not have my vehicle serviced at a Nissan dealership. However, two weeks prior emma lancaster admitted to me that the transmission should not have broken down at this point in time. End result: I paid $3,600 to fix a transmission (which took one month to replace and repair) and paid $1,200 to lease a rental car (another $ amount that Nissan will not reimburse me for) until the transmission on my Quest was installed. According to Nissan all parts of the 2004 Quest are discontinued and they had to send out to have a new transmission built. I will never lease or purchase another Nissan product and will spread the word to other consumers not to purchase any Nissan vehicle. The products are unreliable and the customer service is horrid.

We have been complaining about transmission problems since about 23000 miles. The most recent incident occurred on 15-17 Mar 2007. On arch 15 my wife was driving at highway speeds and she turned from one road on to another and heard a clung. As she drove on she felt the engine was working hard and heard loud unusual noises. Looking down, she saw that the automatic transmission gear shift had moved from drive to low without human help. Over the next two days the transmission was sluggish, and was reported in person to the dealer that Saturday on March 17. I asked a representative to come and drive the van on the spot to experience the sluggishness, the representative declined. The transmission remained sluggish throughout the weekend, until I took it in for inspection on March 19. During March 19 & 20 the technicians could not find anything wrong.

- Fayetteville, GA, USA

On three incidents, the engine will rev however the vehicle failed to accelerate as though it was in the wrong gear. If the engine is restarted then the problem clears itself however that may not be possible when driving on a highway. Took the van to the dealer with several copies of complaints filed by others, however they are not able to replicate the problem therefore nothing was done. Nissan should seriously look into this problem and not address the problem because they cannot replicate the problem.

- Hilo, HI, USA

My 2004 Nissan Quest SE with 20,000 miles failed to move when in (D) gear and accelerator applied. While in a traffic jam, the engine revved but vehicle experienced no forward motion as if in neutral. About 5 seconds later the vehicle lurched forward, and we almost hit the vehicle ahead of us. Minutes in the same traffic jam, the vehicle went into this "neutral" mode again. I put it in park and back into drive, to avoid an accident, and the vehicle moved sluggishly forward, then proceeded normally. This happened once more that day.

Grinding noise upon initial start of day and several failures upon initial start; sluggish and feels like it'll cut off on incline and acceleration. Upon several complaints when auto was a few months old regarding not going into gear and slowing, Nissan put in some computer chip relating to the transmission. They claimed they could not duplicate problem and slowing probllem continues. Also problems with defective interior equipment such as middle row side lights falling out recessed housing, no tension in arm rests, skirts on middle seats don't stay attached, middle pass side door hard to open, rubber on door pulling apart, middle door, drivers side, looks off track, etc.

: the contact stated there are multiple problems associated with the vehicle. First being, the brakes made a noise when applied. Second, while attempting to accelerate, the transmission remained in third gear. This would not allow the vehicle to accelerate properly, at any speed. Thirdly, the sliding door on the passenger's side opened while driving. The contact was able to close the door, although it took much force to do so. Lastly, the driver and passenger side vents had hot air flowing through them. The temperature gauges were adjusted; however the hot air still flowed. As a result, the air conditioner was turned on in order to maintain a comfortable temperature. The vehicle was taken to the dealer numerous times for inspection and solutions to these problems; however the problems could not be duplicated.
