Sounds like my 2014 Sierra Denali 6.2. Mine rattles at like 30mph. On mine it’s the two fuel lines from the charcoal canister going towards the engine. Have some one rev to the RPM and grab those lines and pull on them. Sent from my iPhone using Tapatalk Pro

I don’t use the tow haul when empty or small trailers. It’s shifts too much on small inclines or braking. When loaded the I definitely use tow haul. Sent from my iPhone using Tapatalk Pro

I installed the gen 2 in my 2017 Suburban and it only works when it wants to. I cut up my 2014 Sierra console lid and installed my own and it still works. Sent from my iPhone using Tapatalk Pro

I’ve been down this road also with no luck. At one point my cousin found a match but it was stupid expensive. Let us know if you find something. Sent from my iPhone using Tapatalk Pro

Does the cigarette lighter work? For some reason I remember someone telling me that the OBD2 and 12v socket are the same fuse. Sent from my iPhone using Tapatalk Pro

1.5 front with factory rear. 33/12.50/22. I am thinking I want to paint the fender trim. It hasn’t bothered me much until lately and I am thinking it’s time to get rid of the textured plastic. Next to my old truck at work. Sent from my iPhone using Tapatalk Pro

The dealer just called and said my truck was ready. This is the second trip. The first visit was a new torque converter and basically a trans rebuild. Dealer said it was fixed. Drove it for 2k miles and still the same. Second set of tires and also new brakes. This time I told them I have a third set of factory 20s with 11k miles on them if they want to try another set of wheels and tires. I’m not letting them off the hook so easy. If I can’t get any action from GM my next stop will be a driveline shop also. All I can say is good luck! Lol On the plus side the did give me a 2019 to drive as a loaner.

My 14 Denali is the same way. Sometimes it’s great sometimes it shakes really bad. Same roads. I just got my truck back from the dealership. I replaced the tires, pad, rotors and CV joints before taking it into the dealer. From my experience they will place blame anywhere they can. Perfect example they told me my new tires were the problem. I told them no it’s the exact same vibration as before new tires. They replaced quite a few parts in the trans and it still does the same thing. I just noticed they said my tires were starting to cup. The new tires didn’t even have 300 miles when I took it to the dealership. My old tires didn’t wear uneven or have cupping. Frustrating..... Sent from my iPhone using Tapatalk Pro

I came to ask the same question. Kinda funny it was the last post. I have tried to keep up with this thread and all the attempted fixes. I’ve thought about keeping weight in the back but I would drive me crazy knowing it’s not fixed. 2014 Sierra 6.2 4x4
