The 8th Generation
Got a whine on cold start last night. After 2-3 minutes of driving it didn't go away, so it's not that "normal" PS whine.
Also saw that my voltmeter was reading low, 13.6-13.7 instead of the usual 14.0-13.9
With a 3/8" extension as a stethoscope, the whine comes from the alternator.
