Mitsubishi Repair Problems? Ask a Mechanic for Answers ASAP
Once it starts it continues until you stop for awhile. Noise pitch doesn't change, just how loud it is. Thanks.
Sounds like a supercharger, a high pitched whine that you can hear when cruising and gets louder when you accelerate. In front middle, sounds like it is close to the dash. Doesn't seem to be from motor or tranny necessarily.
I was thinking alternator or a/c fan or compressor but compressor turned off doesn't stop the noise. More familiar with older cars for sure.
The whine lowers in pitch on deceleration
Once you have been driving for awhile and/or above 65mph
