Hello, I have a 2009 Pontiac Torrent with 25000 miles on it. I was traveling at 65 miles an hour when it started making somewhat of a growling noise or what sounded like excessive road noise. I let off the gas pedal and it went away immediately and when I pushed down again it continued making this noise. I did this a few times to make sure it wasn't just road noise and I pulled over and when at about 30 miles an hour I tried to accelerate and it made the same noise. I crossed the highway and pulled over to do a quick inspection and found nothing. I then traveled for the next half an hour home and it was completely normal. There was no problem accelerating or anything other than a real rough noise when depressing the gas pedal and only made this noise for a short time. I had filled up with gas about 10 minutes earlier and other than that just normal driving. Does anyone have any ideas what might have caused this. thanks in advance.
