2014GMC

Found a lawyer and sent the dealership and GM a final attempt to fix letter on my 2014 Sierra. Heard back from GM and they are setting it up with the dealership that I purchased it from. They could not fix it the first three times so I doubt anything will change. Sent from my iPhone using Tapatalk

Tell us more about this! Has he fixed a truck with the vibration by changing axels? Sent from my iPhone using Tapatalk

Took mine in for a recall check today and drove a new 2014 double cab they loaned me straight off the lot. Same shake as mine and maybe a little worse. Dealership said they had a list of 15 trucks waiting for a fix. I bet it's really more. Sent from my iPhone using Tapatalk

I notice when taking off some what easy that the engine shifts really early like 2000 rpm at each shift and feels like it bogs down and has no power after each shift. I think it's a gas mileage programming that is doing this. Maybe I'm just used to the older 5 speed transmission that shifted smooth and ran thru the gears a little more.

Make sure you call GM corporate and open up a case with them. Let's get everyone's problem on record with them. I did this last week. Got a call from the dealership service manager a day later and admitted their is a problem. Said they have been instructed to not do anything else as GM engineers are working on it and when there is a fix they will do it. Said she had a list of trucks with this problem waiting on a fix. At least they admitted to the problem this time and not tell me it's operating as normal. Now fix it! Sent from my iPhone using Tapatalk

So I get the feeling this will be one of those issues that they never admit to or find a fix for. Has anyone successfully lemon lawed one of the new trucks due to just the shake and vibration? class action suite we could all start to get this taken care of? I have driven it for almost 2 months and 2000 miles and it drives me crazy on the interstate. Sent from my iPhone using Tapatalk

At least your dealership is trying something. Only thing I get is the GM engineers are working on it and when they find a fix we will fix it. Sent from my iPhone using Tapatalk

Local stealership advised to have the tires road force balanced and the tires must be below 15#. This is not the GMC dealership I bought it from but a contact at a local Chevy Dealership. Sent from my iPhone using Tapatalk

Don't waste your time with the GM help here. After not calling me twice as promised and having to hunt them down they told me that the dealership said it was normal and that they stand by the dealers! End of story nothing more they were going to do. So the help is all for show Sent from my iPhone using Tapatalk

No mine was built in 2/14 and has the shake. Sent from my iPhone using Tapatalk

Spoke with GMC chat tonight about my shake issue. They said they spoke to the dealership and that it was normal for this vehicle! I said your telling me the bad shaking like it has a bad wheel is normal? They said yes. What a freaking joke. Guess I'm back to the dealership to fix it or lemon law it. Any suggestions on how to deal with this? Sent from my iPad using Tapatalk

So what's the leading theory on the shake. Torque converter? Sent from my iPhone using Tapatalk

They have to have some idea of what this problem is and how to fix it. Stick a few engineers on the problem for a few days and let them get to it Sent from my iPhone using Tapatalk

Had 1.5 hours of highway drive time home today. Averaged 20 MPG for the last 50 miles. Or at least that's what the truck was showing. Crew Cab 4x4 with the 6.2 70-75 mph, 55 degrees, pretty much flat interstate roads on I-10. I'm pretty impressed! Sent from my iPhone using Tapatalk
