One problem related to brake grinding noise has been reported for the 1999 Nissan Quest. The most recently reported issues are listed below.
I started having problems with the brakes and the air conditioner around the same time frame give or take a few weeks. The brakes started making a grinding noise when it was about two months old. I took it to the dealer the said they did a complete brake job on it. Since then it has been back to the dealer 5 other times due to brake noises that are still not repaired. My van also vibrates at speedso f 60 miles or faster, also it has had 3 front end alignments in less then six months. Then with my air conditioner they say the noise was normal that it was suppose to sound like it was going to fall out in the driveway when I turned it on, and when Nissan came out with a fix they would contact me. To this day they have not even looked at the air conditioner other then to check the belts on it. Both my brake and my air conditioner are still making noises. I have two friends that own Nissan vans and there vans do not have these problems.
