Had a brake fluid flush and software update last week. Engine noise for some reason is much louder at 50-80 mph - sounds like a growl/whir noise. Prior to update drove car about 550 each way and car was much quieter. Wife even commented that car sounds louder.

Anyone else experience this? What could they have done wrong. Car has about 7700 miles. Its a 08 leftover that I leased in Jan 09.
