My 2004 Nissan Quest SE would loose power when slowing down to 30 mpr. I was told that 2nd or 3rd gears are lock engaged. It would then make a load crushing sound like the transmission was knocking against the gears. This is very hard to drive early in the morning. I took the vehicle to aamco. They told me that I can have a rebuilt transmission for about $2300. I don't know about you but I can not afford this on my income and out of work. Do anyone have a solution to this problem?

Had this van towed to nearest repair shop 25 miles and had the throttle body replace. There was no check engine light on prior to this repair. Parts that was defective was the throttle body, ignition coil and was told by repair shop a possible defective fuel injector.

1). transmission - 29,889 mi. To present. Serviced 6 times. Constantly shifts up and down at school zone speed, loud clunk when decelerating at 40 mph, loud clunk when decelerating in highway exit curve. Dealer says everything is working to specs...nothing fixed. 2). brakes - 46,363 & 55,204 mi. New front and rear brakes installed. At 73,014 miles van needs new brakes and rotors. 26,651 highway miles. Wallace Nissan service said Nissan used undersized rotors for vehicle weight and tire size, hence need for frequent replacements. 3). electrical - 04/05/2010, 64,194 mi. The vdc and ck engine lights came on, van speed very erratic...5 to 40mph all by itself, stalled several times. Dealer computer diagnosis...faulty sensors in crankshaft and camshaft $209.07. 10/03/2011, 72,547 mi. Same vdc and erratic speed. Dealer's initial diagnosis, faulty throttle sensor, installed new sensor...same problem, upon further investigation dealer found the ECM unit was totally corroded and had to be replaced. $962.16. Nissan mechanics say it was a faulty design location of the ECM right under the windshield wiper cowling which allowed water to enter the ECM, corrode it and cause its eventual failure. In subsequent year models of the Quest, Nissan moved the ECM to a more protected area. 4). electrical - sliding rear door sensors continue to fail as the door shuts to prevent injury to a person with a hand in the way. Sliding doors continue to rattle even after 6 service visits to fix it. 5). electrical. Rear hatch motor and lock mechanisms continue to break down even after 6 service visits and $1,164.94 in repair costs. 6). other problems involve: Faulty backup sensors, serviced 4 times $285.88. Same drive belts replaced twice within 26,651 miles and $250, leaking sunroof and skylights, Nissan had to replace the entire roof because of severe rust. Overall, van is crap!

Timing chain rattling.

- Round Rock, TX, USA

I went to my local Nissan dealership for an oil change and was very surprised to have them to tell me I needed a timing chain replacement. I was so surprised because I have had this van at the dealer for repair at least four times over the past two months and was told there were no problems with the van. I feel that Nissan knows there is a problem with this timing chain due to the comments the service techs were making.this is a $3800 repair that is due to poor design by Nissan, I was told they put the metal timing chain on a plastic guide. I feel that Nissan should have to make this right with its customers asap!

In December of 2006 we purchased a 2004 Nissan Quest SE. The first year was not entirely trouble free, the drivers seat would self adjust while driving. The dealer fixed it no charge. The in December of 07 the trans went out, again the dealer covered it at no charge, gave us a loaner and were done within a week. Except for the inconvenience of not having our van we were fine until now!!! in June of 08 we were going for a Sunday drive and the van just died in the middle of the street. Nothing would work nothing, no power anywhere. We called road side and all they could do was tow us to al piemonte Nissan in melrose park, il. The following Monday, the dealer calls and tells us the ECU is burnt out, and has some corrosion. It's covered under warranty so no need to far right!!! a week later we finally get a loaner, ok not too bad. Two months go by and we finally have word that we have a date when the part will arrive!!!!! the part gets installed but the van runs like crap "omg you mean they actually tested it"!!!! they now are replacing a cracked distributor, god only knows how that happened!!!! the dealr does not charge us for that, but the van still runs like crap so now they have to replace three of the 6 coils and well we had to pay over $800 bucks for that. Totally not expecting that we had to charge it, putting us in the hole even deeper. You know we haven't spent alot of $ on this car but for a 4 year old car it sure has had alot of major components replaced. The the freaking dealer doesn't test the car, so we leave and the remotes, doors, sunroof, windows don't work. The center counsil is falling apart and they didn't even clean the '!@#$% car. I take it back, rip the manager a new one, he gives me a loaner again and I'm back the next day to pick up my van, now they clean it. It's been a few weeks now and the van is fine but I often think what would have happened if it broke down in the middle of the interstate!!!!!

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.

Caller has had van for a little over a year and in November 2004 the brakes started making a noise and van would not respond to giving it gas. Caller stated the rpms revved, but the van would not accelerate. The caller said her husband hit the brake and the steering wheel shook. The brake rotors warped and the axle needed to be rebuilt. The transmission shift unit also needed to be replaced. Dealer replaced the rotors and they were rebuilding the axle and replaced transmission shift unit. Manufacturer has been contacted. The caller was waiting for them to call her back.
