At 60000 miles had to replace the passenger wheel bearing and ABS sensor in the vehicle. At 90000 miles a knocking sound began to come from the engine while the vehicle was stopped or in park. Mechanic advised this was due to the timing chain, which is a problem due to the plastic parts that Nissan uses to hold the tension on the chain. This is a known problem with this model vehicle as numerous complainants have been filed. Concerned that Nissan knew it had a bad component and has not fixed the problem that exist. Also, now the driver side wheel bearing is bad and needs to be replaced. Started to have problems with the brakes around 30000. Fixed the brakes with oe parts, and then began to have problems with the rotors. Technician advised these problems came from the rotors getting hot. Had the rotors turned which did not work. Now I am going to have to replace the rotors on the front of the vehicle. Window motor also has went bad in the vehicle.

2007 Nissan Quest brake/rotor issues. Brakes and rotors are wearing rapidly at very low miles. It happened at 45,000 miles and again every year since. Even after having brakes and rotors resurfaced a few times. Continuing problem. Dealer thinks may be driving habits, but device placed on car to track driving behavior by insurance company shows no hard braking. Possibility that this vehicle has similar rotor/brake problem due to weight of vehicle or improper cooling like titan truck did early on. A rear end collision my wife had in late 2009 may have been related to the this problem. Several hundreds of people have same type of problem on internet vehicle problem sites.

I was traveling down a 6% downgrade on a freeway in my 2007 Nissan Quest. At the time (Jan 2008), the vehicle had about 15,000 miles on it. I was continuously braking to keep the vehicle at a safe speed. As I was braking, the brakes began to pulsate. The pulsations got louder and more aggressive as we continued down the downgrade, to the point like if felt the brakes were about to fail. Soon after, in January 2008, I brought the vehicle to the Nissan dealership in bellevue, wa. They acknowledged the problem with the front passenger brake rotor was warped. They resurfaced the rotor. At 9 months later, and at 25,000 miles (Oct 2008), the pulsations started to reoccur. I brought the van to the same dealership, and this time they replaced the same rotor they resurfaced 9 months earlier. Again at 35,000 miles in July 2009, the pulsation problem returned again. I brought it to united Nissan in las vegas, but they refused to address the problem, citing normal wear and tear on the brakes. Finally, in October 2009, I brought the brakes to a brake specialist. The specialist stated that the front passenger brake, the same brake that had continuous rotor warping, was defective due to a faulty brake pin causing sticking between the caliper and pad, which was the root cause of all the warping and pulsations.

I bought my 2007 Nissan Quest in April 2008 with only 26 miles on it. I noticed within a couple months that when going over 30 miles an hour the brakes did not engage right away and I had to pump them once or twice to get them to work much like my 20 year old car when I was a teen. In Sept 08 I was in an accident when driving 35 miles an hour with a good 5-6 car lengths away when the car in front of me suddenly stopped and I could not stop. There was not enough time to pump the brakes and when I pushed hard on the brake it went mush all the way to the floor. I ended up hitting the car in front of me hitting my head and getting a concussion. I was out of work for 2 weeks, had over $6,000 damage to my van and over $4,000 damage to the car in front of me who then hit the van in front of it and caused $3,000 damage to it. In total 4 people were injured I was injured the worst and spent the night in the hospital. When the body shop sent my van over to the Nissan dealer to check the brakes they said they reset the ABS and they seemed fine. I talked to them and asked where they tested the brakes their answer was in their parking lot and around the block. I asked them to drive with me over 35 miles, they refused and said the brakes were fine. Since that time I have had to drive 10+ car lengths behind everyone to make sure I have time to pump the soft brakes. If I had the money to eat the cost of buying a new van when I still owe so much on this one I would be doing it now.
