Nissan 2004 Quest, while driving and making left in intersection van dies. Take it in to nssan dealership and unable to run diagnostic test due to engine not running. They believe its a timing chain problem and need to open engine.other consumer reports with problems with timing belts. We're a family of seven, if it would have happened while on freeway most likely would have had fatalities involved. Nissan refuses to practice any goodwill financial assistance.

The timing chain guides (teflon based material) in the VQ35 engines were prematurely causing audible rubbing and banging upon start up and early warm up idle conditions. This premature wear of the tension guides is a safety hazard due to the fact that the timing chain has undo slack from early degradation of tension guides which may cause the timing chain to wear/break prematurely and without warning while driving at highway speeds. This would cause the engine to shut down unexpectedly and put the lives of the vehicles occupants in danger of possibly being struck my oncoming vehicles.

My van had the red key warning light go on and smelled like electrical burning. I had it towed immediately to a Nissan dealer kelly Nissan lynnfield MA. They did check the bulletins until after test driving it twice and burning out the ignition coils they just replaced and burned out my catalytic converter (they put a new one on without reporting it) they were advised in writing not to do any work except replace the coils they said they burned out and only then at no cost to me. They replaced more than what was originally written, charged me and when they test drove it and ruined the converter it sucked up debris into the engine and destroyed my engine. Called corporate Nissan who said they could not help ( after they gave a $300 coupon because of the deception prior to finding out about the damaged engine). It all started from a loose ground wire that caused the coils to overwork and burned out. I ended up paying about $900 for repairs because the misdiagnosed and damaged parts, now the engine is estimated at 6800. To replace. I M disabled and barely able to afford the roof over my head and food. This is unacceptable behavior, niss says the dealers are independantly owned, yet they L have the same maker. I kept the coils they put in however they removed a box with the first replaced ones and did to put them all back for me as instructed. I have two technicians one a Nissan tech who says it is directly due to kelly Nissan's misdiagnosis and driving of the car to the point of burning up the parts. What does a consumer need to do to protect themselves? the car is out of warranty. All parts except the converter they also kept and the initial coils I have. The van was towed to the shop I used and engine light came on immediately from first time driven still in dealer lot, they could to find problem although heard sound from engine and read the misfire codes until second look after it started pouring smoke out the exhaust and sound became so bad and car was deemed unsafe to drive.

Was told on 6/28/08 that my Quest needed a new "brain" for the computer and this is what was causing the vehicle to not go out of second gear. We are still waiting on the part and Nissan usa has no answers for when the part will be in. They have refused us a rental because it is not their policy because the 5/60 warranty is out, but the part to the engine is under warranty. The car is unsafe to drive - the transmission often slips as well as provides no acceleration most of the time.

I have a 2004 Nissan Quest S. in November 2007 I called the dealership to complain that every time I start my van it blows out white smoke. I had about 58,000 miles. I bought the van used from a Nissan dealership. I was never informed that the warranty was extended to 60,000 miles. The mechanics advised me to put in some no smoke/ no leak into the oil and I should be fine. So, because these are professionals, I listen. The problem persisted so I called Nissan Consumer Affairs department. They advised me to take it to the dealership to be diagnosed. I now had 61,000 miles. I took in my van and they kept it all day. They called to say they needed every receipt of oil changes, to prove I kept up the maintenance. They said I have a sludged motor and need a new engine. Nissan will not help me because there is no record of me calling before my warranty was up and they said it was lack of maintenance, not covered. Even though I gave a years worth of oil change receipts. Also, they never actually ran a diagnosis test on my van. They just used their expertise, and experience to come up with a sludged motor. Later my van starts vibrating quite badly when brakes are applied, so I take it to a mechanic who says I have a misfire, and a blown head gasket. (they also say this could have caused the sludged motor). I replace the spark plug $250 later. I call Nissan again and say what I have been old only to be told it still would not be covered, that I need a new engine. That it isn't their responsibility to make sure the van was kept up before I bought it. I feel that if I buy a certified preowned vehicle I should not have to worry about putting in a new engine. They said if I didn't like their service I should contact the BBB. I feel this is unethical, and poor customer service. They will not help with anything and meanwhile, I am still making payment on this van. They quoted me $5,000 foe a used motor and it would only have a 90 day warranty.
