The current issue is a tone (probably around 800 to 1k hz) while driving around 40-60 mph. It gets louder if accelerating and softer if letting of the gas, but is present even at holding speed. Turned off the audio system to make sure it wasn't coming from it. Sounded like it was coming from the rear of the vehicle. It started doing this right before my trip above, but I decided to wait until I got back home and take it to my local service dept. They had 4 different people from the dept test drive it trying to figure it out. Also discussions with people at corporate. The diagnosis was something in the rear differential. They opened and inspected it. I was told after they removed the ABS sensors, they found metal shavings inside. End result is that I'm getting a new differential.
Feeling a bit depressed about this purchase....2 significant issues in the first 2700 miles. 1st was a blown AC hose while I was on a business trip in Virginia. Wouldn't have been a big deal, but it was in the high 80s with 90+% humidity that week with periods of rain. Very uncomfortable in such heat when the rain forces you to close your windows! Had to take it to a dealer to have them fix it. I'm starting to think I may have a potential lemon on my hands. I haven't bought new in over 25 years and my last 3 purchases have been with Chevy. I didn't expect to have issues so soon with a brand new truck. I had to pay for my rental on the A/C repair and will need to file a claim with corporate for reimbursement. Yes, everything is under warranty, but it's a hassle to have to deal with.
But, I digress....anyone else heard of such a problem causing a tone like that? The service rep couldn't explain how, but they are telling me I'm getting a new differential by Monday.
