: Light whining noise

11-02-10, 10:55 PM
Have a 2006 STS V8 and I have noticed a slight high pitched whining noise when I start the car and when the car is accelerating and warming up. It seems to go away after awhile. Any ideas? 40,000 miles on the car

Under light acceleration & stops when you step harder or let off. There's a TCM reflash available. If it's only when cold, you may want to knoe the reflash is not reversable.

check fan belt,power steering pump, water pump, ac pulley and/or clutch, idler pulley or tensioner if so equipped

ALSO.....Power steering fluid, is a major contributor for whining noises.:cool::cool:
