I have a 05 Yukon SLT. I noticed that sometimes when I turn my truck on I get a weird noise. It's not the autoride air compressor, I get that every other time I turn my truck on. I turn it on and it'll idle for 2 seconds and then it makes this cranking noise for just a second, and then it's gone and it's like nothing ever happened. I was just wondering if anyone's experienced this noise. Hopefully it's not something big that might cause big problems down the road?? I only have 70,000 miles on it..
