Yes, it is me again with more bad luck. However, this is with my 2013 CTS Coupe. Finally been having no issues with this one and its been driving great. Went to the outlets to pick some things up. I came off the highway at about 70MPH and slowed down going down the off ramp but the exit was right off the off ramp and I tried to make it. Breaks locked up and I missed the turn. Went and did the U-turn. Long story short, I noticed a semi-loud (abnormal) sound towards the front right wheel area right away. It sounded like a motorcycle is revving the engine which is what I thought it was until I noticed it was my vehicle. Not crazy loud but absolutely noticeable to know something was wrong. I was going about 10MPH in the parking lot and anytime I hit the gas peddle to accelerate slightly I heard the sound. That's the only time I hear the sound is when I push the gas peddle. It is still going on right now but seems to be slightly less noisy. Any ideas as to what this could be? Something major or nothing to worry about? Any advice would be appreciated. Really hoping its nothing major but sounds odd.
