Antone having any issues with the 6.2. Im close to getting mine bought back, Im not willing to drop another 15k on a 2500 so looks like Im gambling with another 1500. Maybe a more recent build date and a different engine will eliminate some possible issues.

Well folks, I did it. After all the failed attempts at the Chevy dealer I traded it in for a 2015 Ram 1500 Larame. I have to agree with the other folks on here that have done the same thing, it was th

Apparently you and the other customer reps don't care. If you or GM would care y'all would put more effort in the matter. Just coming on the forum and stating the same repetitive posts and being a 3

Well I have some good news and bad news about my truck vibrations. Good news is that my truck has a significantly less vibration at speed. The bad news is my truck has significantly less vibration. Fo

Bolt the flapper open on the exhaust and see if that helps, it took my v4 drone/vib away, and then go and have the dealer order you the updated exhaust if your truck was built before December 8 2013

 

 

My truck was built 03/14 and had vibration and squeaky between v4/v8. It also sounded like a turbo with as much as it whistled. No update IMO & its just crap their feeding us. I clamped mine and solved my problem myself.

Ok quick question, well two. One, where can I find this flap exactly some can do it and two would a aftermarket exhaust work better/ take care of the problem?

The adaptive valve is right behind the muffler and yes an aftermarket would eliminate the dumb @$$ valve. Truck sounds better as well with it open

a few pages back someone posted a link to the fix so I printed it off and took it to the dealer and asked if they seen this and they said no but then they popped the service bulletin right up on there computer. We went out and got all the info of my truck like the build date and the number that is stamped on the muffler and mine fit in the bulletin so they ordered me the new one

Just got mine back from the dealer after four days. They balanced the tires and said I need to break in my suspension and the vibration would go away.

That's a joke!

Take it back! Tell them to road force the tires or replace them, and then drive another new one on the lot and prove that your truck doesn't need "braking in"!

A friend of mine has a 2014 LTZ Z71 with over 17,000 miles on it and his vibrates at speeds over 70+ mph. I think it's the tires. But it's definitely not in need of "breaking in" at that many miles so I'm calling BS on that response from the dealer.

They road forced them and said it was only 10 pounds off. I drove another while they were working on mine and it was smooth as silk on the interstate. I bet I will be stuck with it

      OCI, not when but why?

      By KARNUT · Posted

      I’ve own several successful businesses. I’ve bought homes and lived in different states. I’d witness several generations buy homes and survive in different economic circumstances. You get awful sippy when people have different experiences than you do. You live a life. I’ve lived a life. It seems our experience has been different. You can point out generalized statistics. Some people learn how to thrive when the odds are against them. Living in different states does make a difference in a persons quality of life and economic outcomes and opportunities. That’s a fact Jack. It’s my truth, my life. Hard work and long hours the right environment made my families life easier. And yes moving to a different state increased the odds of that happening. Stats are generalized. People who thrive don’t make excuses. They beat the odds. Others get mad and point to those statistics. I guess that’s you. My post pointed out how you helped people beat the odds. Somehow your panties got in a wad. Go figure.

      By Grumpy Bear · Posted

      Point of the post sir was that while both wages and cost are rising EVERYWHERE; the cost is rising faster EVERYWHERE than the ability to buy EVERYWHERE. We're not going down the location rabbit hole. I'm aware of what economic migration is. I've lived in four states including Texas.   It's what "Purchasing Power" means.   I'm not telling you what I think. I'm telling what the government, your government, data shows.   It wasn't an argument. It wasn't a suggestion. It was a statement of FACT. You are absolutely entitled to your own opinion. Your not entitled to your own facts. If you and I were, they wouldn't be facts.    fact /făkt/   noun Knowledge or information based on real occurrences. "an account based on fact; a blur of fact and fancy." Something demonstrated to exist or known to have existed. "Genetic engineering is now a fact. That Chaucer was a real person is an undisputed fact." A real occurrence; an event. "had to prove the facts of the case."

      Transmission jumping out of gear while driving.

      By JimCost2014 · Posted

      Probably a one and done post, but do you have a CEL on the dash? Was having issues with my transmission, fortunately only a week, and it turned out to be the transmission harness. Valve body was in good shape, so new harness with all the sensors attached, new fluid, and filter. Seems to have worked so far?

      Missing thrust bearing? And oil selection

      By Atlas · Posted

      Two interesting tidbits of information which are NOT related were just released.   One, regarding the possible thrust bearing issues / engine failures with the 3.0. Demonworks just did a segment in which they believe they may have found "a" or "the" cause of thrust bearing failures: A missing thrust bearing. If the engine doesn't have all its thrust bearings from the factory, the missing bearing can cause extra play which ends up destroying a nearby thrust bearing which then sends metal through the engine.       Of other importance, Lake Speed Jr released some interest information regarding oil weight selection for the 3.0. Comparisons of:   AcDelco 0w20 Dexos D Mobil 1 ESP x2 0w20 Dexos D Mobil 1 ESP x2 0w30 Mobil 1 ESP x4 0w40. Mobil Delvac 5w40   Spoiler alert: The Mobils are PAO Ester -base and the ACDelco is a Group III base. Mobil shows lower wear in their tests for similar weights. Additive packages between 20-30-40 weight ESP's appear to be the same, but only 0w20 is Dexos D licensed. Wear is even more reduced with 30 and 40 weight ESP although all perform very well and resist shear and provide very similar viscosities within temperature operating ranges in the 3.0.   There are even more surprises, so just go watch it.
