I'm having a high pitch whine coming especially from the passenger side. The pitch gets louder with RPM changes. It's constantly there, as soon as the car is on, whether the car is idling, accelerating or decelerating. This whine comes from the speakers, because when I disconnected the oem bose amplifier, the noise was gone. I believe this is known as the "alternator whine" so I changed a new alternator told by the dealer, and changed to another oem bose amplifier, but the "whine" still remains. The high pitch noise is very annoying and causes migraines.

My new 2007 Nissan Maxima was "bucking" at 40 mph & 60 mph. The service engine soon came on. Later that day, the vehicle stalled out on me 3 times. The next day I was able to drive the vehicle to the dealership. They indicated that it was the cam shaft. The next day I was able to pick up my vehicle. However, I couldn't get it out of the dealership parking lot after stalling 3 times each time I put it into drive. The mechanic was authorized to take my vehicle over night to drive it after being able to test drive it. I was informed the next day that the mechanic couldn't get it out of the dealership parking lot either. They have been in touch with the manufacturer, but they can't seem to locate any error.
