My exhaust manifolds look just like that and did so from day 1. My 2007 looked like that too. I wouldn't worry though pretty much all of the Ecotec engines look like that to some degree. It was never an issue on my 2007 and I don't expect it to be on the 2014 either.

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

Still dealing with all of the same. Truck is back at the dealer after they offered to replace the Goodyear's with Michelins. Got a call last night saying the truck still has the vibration with the new tires and GM wants them to RF balance the new tires??? Why would they have put the new ones on without doing that knowing all the issues we all have. So this morning I get a call saying that all of the new Michelins were out of round and spec and that they are ordering 4 more new ones to try. I cant understand why they have not taken one of these vibrators in to their tech teams and designers at GM to figure this out and issue a fix, makes no sense to me.

I have a 2013 so I don't have a shake issue, but, my frame and cross members is rusted much more than I would like. After seeing the pics above I was wondering if any of you guys have looked under your truck and have similar issues with rust? I did a google search and its all over the internet but I dont see it discussed here.

it slipped off the first page what with the long long list of many issues these trucks have going on with them but here is the thread for the people discussing having frame rust issues

Like Jay Leno would never, never, never turn his car over for valet parking (see Jay Leno garage Challenger hell cat review 9 mins in, funny), I would never trust a dealership tire balance efforts. Find a good tire balancing shop. I have bought many. many Michelins LTX and sports for the last 30 years and had only one tire out of spec.

Yeah no way 4 new Michelins are out of round and spec.

 

One out of round/spec, maybe and that's a HUGE maybe.

Two, I doubt it.

Three, no f*****g way do I believe that.

Four: Ok I'm on a hidden camera show right?

 

Michelins are probably the least likely tire on the market to be out of round and spec. The dealership is just stalling.

Or getting tires from a bargain basement.

For any of you with the high speed vibration - have you tried shifting into neutral well above the speed where it starts shaking, and does that change the shake at all?

 

Has anyone answered this?

Dropsix I did try the neutral thing and different gears (as others have) with no change in vibration..

Now I did just pick up the truck from the Dealer with the four new Michelin's and the vibration is gone, for now. It does ride nice and these tires should be OE on these trucks. One thing I noticed on the drive home was that they are very quiet compared to the GY's, which was a surprise to me because I thought the truck was real quiet to begin with. The only time I could really hear them was on concrete sections of the highway. I have had this vibration issue in the past and was taken care of with four new GY's about 4000 miles ago. Now it rides smoother than it ever has but I am obviously concerned that the condition may come back. Also the exhaust was replaced for the whistle condition which is now gone also. Also I did run different speeds up to 94 mph and did not feel anything or see the passenger seat vibrate at all, so fingers crossed.

Does anyone have this issue with factory 22" wheels?

I had the issue with 22" after markets. Went back to stock 18's had vibrations with the good years put on new hankook winter pike tires and I have no vibrations anymore. I consider myself lucky for the time being.

Just picked up '14 Denali with 8/14 build date and no vibration/shake after first 150 miles of driving. Want to thank you all for speeds/rpm to look for while driving. Hopefully mine stays that way and those with problems find a solution or other positive outcome.

Seems like the late build are vibration free. Have yet to see anyone with a late build complain.

. Thought I read somewhere stating some people having troubles with the 15s vibrating

      TCM Tuning 6L80E

      I did the new thermostat after doing a 'flip' for a year. Runs as cool one way as the other in the summer but in the winter there is a bit of a floor. Yellow with the new 70 C thermostat. My data over the life of the unit to date. Still need more cooler. Anyway that floor helped both winter fuel economy and shift quality in the winter. I found it a good balance.

      Evan Williams Bottled in Bond   So pouring the last of a bottle of Evan Williams Black label last night I set off the the state store for a refill only to be denied the by an empty shelf. Rats.    What the did have was a bottle of Evan Williams Bottled in Bond. 100 proof. Hum, a few bucks more but a known distiller. Lets have a swing at it. ( I have before )    Cracked it open and pour a serving over ice. Hum.... more heat, yes. More alcohol naturally. But the barreling not the proof brings the taste and this one came up short.    Oh is was familiar but the heat ran the barrel over like a Peterbilt runs over a squirrel. Could use a heavier toasting of the oak me thinks or perhaps a longer barreling. Who knows. But what I can say is ice or a water back isn't the answer. What kills one kills them both. Sad. It is a pleasant drink....if you have little to compare it to.

      Bridgestone vs Goodyear tires?

      By Grumpy Bear · Posted

      I've had exactly one set of Bridgestone. Lasted five year and 125,000 miles and had I known better 15oK would have been a cake walk. I would have bought a like set had they not tripled in price since the first set. I removed them at said mileage with 5/32" remaining in dead even wear all four. They were fuel efficient, quite, comfortable and predictable.    Early on I got a very good alignment checked at least once a year, sometimes twice; kept the tires properly inflated, balanced and rotated. And I've found that many a tire issue can be avoided with great maintenance practices. Lot's of tire dealers will do rotation and balance (simple) for free for as long as you own the tire they sold you so no excuse not to.    Bead prep, alloy integrity and stem health have a huge impact on inflation stability. There are more mountings done poorly that perfectly. Finding a good tire guy is gold and as important as finding a tire you like.    That 3X price increase now two sets of "other tires' later is starting look like a bargain.      Bad maintenance kills more tires than bad tires.

      Wow I'm in a pickle. (Broke down truck) and a story.

      Atlas, you kill me As aggravating as a project like this can be you have been unable to hide your fascination with learning and using that angst against this beast like a Ninjitsu Master. It amuses you, admit it now.      BTW, love your writing style. 😉
