Hi just wondering if anyone would be able to help. My truck makes this rattling noice when being accelerated. When it started it wasn't that bad but has progressively got worse. It's worse when it's cold then goes away for the most part once the engine is warmed up. Sounds like it's coming from the front end. Thank you! 20220307_163644.mp4
I just bought a pre-owned 2015 Yukon Denali and I Love it! I've been waiting for the feel of a big V8 engine with 4 wheel drive so this girl can dirty on any road.. It's beautiful and I'm SO happy to own a sexy Denali. I've only had it for two weeks so I'm learning every thing about it with each drive. So far the engine purrs and all gauges read level. It's got 98k mi on it so I'm expecting it to have some wear and tear. So just yesterday morning I pulled away from a stop sign and gave a good rev got up to 50mph in a few sec... and as I approached a slow zone I took my foot off the gas.. lowered speed to about 25 then gave it a little more gas while going up a slight hill in the road and I hear what sounded like a knocking noise. I took my foot off the gas and the sound went away. So on the drive home where I have to ascend up to about 2200 ft elevation it did it again as I was coasting and had to accelerate from 25 to around 30 mph I kept my foot on the gas this time (engine sounding smooth as silk) and continued uphill about 45mph and the sound went away. It's always a short knocking/rattling sound. Not in the engine but below me, definitely upfront. I've got an appt at GMC next week but until then I'd love to figure it out. Not sure what other details you need but any one got any idea? Thanks everyone! -Dia
I can't seem to pin point this rattling, but I know it's under the steering wheel area, near where the OBD connector is. On smooth roads it doesn't rattle but will on rougher roads. If I tap on the bottom part of the dash I can hear it rattle too. Anyone had this issue and was able to pinpoint/fix it?
