Reading through this thread is making me sick to my stomach.

 

I just purchased a 2016 Silverado 4x4 (4.3L) and with only 700 miles on it it is now shaking on the highway from 65-80 mph. I took it in the other day and they replaced the front right tire and said the downforce and psi something or other was wrong/bad. Well, a day without my truck and a new tire and now the thing shakes more than it did before!

 

I haven't even made my first payment on it yet!!

Contact the manufacture by phone and send a registered letter! Ask them to contact your dealer, and that your new truck is there awaiting a solution as it shakes bad! Do not except it back until it is fixed. Do not go home with it, they will tell you to drive it for a while while they work with you....don't.

 

This is a known problem gm is aware of.

Know your rights.

Ok guys, i finally got the problem fixed after several visits to the dealership. The vibration problem is the ring gear and pinion gear which i suspected in the beginning . Chevrolet had an issue with

Had my truck in for the 2nd time today and they tightened up body bolts, checked complete front end, box and exhaust system. They test drove it and still vibrates steering wheel starting at about 50 M

So got my truck back yesterday. Diagnosis: there weren't any wheel weights on any of the tires. Guess they forgot to balance the tires at the factory. So for now, vibration and shaking is unnotice

Well, day four with my truck still in the shop. They changes tires (just three), changed the driveshaft and it's still has a vibration 60-80mph. They said they have GM's engineers involved now. I'm getting pissed to say the least. Haven't even made my first payment yet!

 

I did call GM directly and they sent my case to the district manager who denied my request for a buy back. He said they're working with the dealership to get this vibration issue resolved.

 

What a huge pain in my a$$!

Have them provide a Truck loaner to replace your truck, do not sign off on the repair until completely satisfied.

 

Use the Lemon Law if available. I did not follow my advice and regret it every day.

They gave me a Malibu as a loaner.

 

They just called me and told me that the "GM Engineer" is there today looking at it.

 

I'm not even sure what to do about the lemon law. I've called a couple attorneys and haven't even received a call back :-/

Well now they called back and said that their "Engineer' has requested to try some steering bushing as that has been a fix in the past...but they won't have the parts this week and I more than likely won't have my truck back until weds or thurs of next week. In the meantime they've been driving it and putting miles on it.

I'm at a loss. He insists that I have to give them an opportunity to fix it but at the same time they're wrenching on a brand new truck annnnd racking up miles on it. I'm calm on the phone but my patience is running out.

Had the steering bushings replaced on my truck about a month ago. I wish I could instill confidence but it didn't work. My steering wheel center console and seats still shakes at 73-77 MPH. Try and and get a buy back or vehicle swap, better yet and go buy a Toyota(they never die) or (I hate to say it) ford....

GM doesn't care, they actually admitted that I have drive line vibration and said they wouldn't do anything. I told them that I researched it, and know it's a big problem they are having, and if they didn't continue trying to fix my truck that I would file complaints and if necessary a suit.... they refused to work on my truck, so I have spoken with a law firm and we are starting a class action lawsuit. PM me your name, email, and phone if you want to be added to the list of contacts I send to the attorneys

What's the status of this?

Guess I will add my truck to the list, sadly. Picked up a new 2017 crew cab, short bed LT Z71 last Saturday, could only test drive to 60mph and that was pushing it bad in that area. I hit interstate yesterday and the shakes start around 65 mph and by 70-72 it's BAD. I called the dealer, largest volume dealer in TN and the guy said to bring it in after I got 500 miles on it but he's never seen one truck with my problem, hard to believe. I go this Sat and already requested a loaner until mine is fixed, my dealer is an hour away so it's a pain.

I know what dealer you are talking about and they have seen the problem because my truck was in there for the same problem. They re-balanced and rotated the tires and sent me on my way. You also don't have to go to your dealer to get it worked on, you can take it any place you want. The selling dealer or any other dealer don't give a crap where you bought your vehicle. Don't know where you are at in SWVA but there are a 4 or 5 others you can go to that is closer.

I'm in the Abingdon, Va area. Did you get a resolution to your problem? Is there a dealer you recommend in my area over Champion? Thanks for the info.

I bought mine in Castlewood VA but had both the Johnson City dealer and Bristol dealer look at it. The re-balancing of the tires cured alot of my shakes (not all of them) so I left it at that, didn't want the dealership to start throwing parts at it without knowing what they were doing. This was 2.5 years ago for me.

Update on my truck:

 

As I mentioned above, they had it for a few weeks. I got it back and to my surprise it does not vibrate/shake anymore on the highway (65-80 mph). They replaced the tires, some body mounts, driveshaft, U joints, and steering bushings. However, I've been driving it now for a few days and now it shakes at 45 mph! I haven't even called them to tell them yet because I want to keep my cool.

 

They did treat me well (only after I told them I researched this vibration problem online and called GM directly). For my inconvenience they installed a bed liner, a tonneau cover, and paid one months payment for me. Now I have to make the dreaded call and tell them that it's still vibrating. I've been driving loaner cars more than my new truck. I wish they would just buy it back at this point. Now it's always going to be in the back of my head. Every little vibration will be magnified 1,000 times because I'm almost expecting it. The bed liner, cover and payment was a nice gesture...I'll give them that. :-/

A small vibration may be experienced through sweeping turns at highway speeds on some 2015 Colorado and Canyon models. The vibration goes away once the roadway straightens out.

 

This condition is called Smooth Road Shake. The Power Steering Control Module (PSCM) has a calibration to lessen the effects of Smooth Road Shake. However, the calibration is inhibited when the steering wheel is turned beyond a certain degree, at which point the vibration may be felt in the vehicle.

 

Do not replace any parts for this condition. A revised calibration is available that increases the amount of degrees from center that the steering wheel can be turned before inhibiting the Smooth Road Shake correction. Program the Power Steering Control Module with the latest calibration available in TIS2Web and verify the repair.

 

If a vibration still exists after the Power Steering Control Module calibration has been updated, continue with the appropriate vibration diagnostics in the Service Information

ALL OF YOU ARE BEING LIED TO ! 
2015 multiple dealers visits - unresolved 

2016 same - no fix

2017 same - no fix

2018 same- no fix

2019 same - no fix ( same poor excuses I have been hearing and reading on these forums since purchased)

2020 same - no fix

2021 so much worse and no fix and no clue, still the same crap on forums and GM will deny until you switch to a different product, very disappointed to want a quality GM product that has haunted me for so many years, good luck but FYI they will not fix if it comes out of their pocket and can’t anyway

      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.

      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. 😉

      I gotta say, I'm enjoying your narration. The troubles you've been having are amusing as you describe them. It's good to see that you're finally getting some satisfaction out the old beast though.

      Declaring victory would upset the demons that possess this Blazer, so I won't. But I did make progress today--after it put up a fight. Always a fight.   I had the day off so I spent the morning cleaning up the shop and I thought I'd get ahead of things by filling the cooling system in prep for the final part I needed to arrive: the driver's side knock sensor. Glug, glug, glug....and then the unmistakable sound of liquid hitting the shop floor. It induces the same chagrin when the sonar and targeting laser temporarily malfunction during a late night bladder evacuation over the toilet with the bathroom light off. D'OH!!! That made a mess...   Oh, hey, that knock sensor I removed? It threads into a wet port. Who knew?! Learn something new every day. Put a pin in that chore, I'll fill it the rest of the way later.   The knock sensor arrived at about 1pm. I threaded it in, connected the wire, filled up the coolant, checked for leaks, and... drumroll.... fingers crossed for a perfect start, excellent timing, model fuel trims, and ...no squeaks... Here goes.....   No, it didn't start. At all. I cranked it a few times and it wasn't sounding good. Furthermore, I heard leaking again. Jesus H Tapdancing Christ, stop leaking all over the dang floor. This time I had accidentally overfilled the coolant reservoir and the churn of the water pump via cranking caused a bit to burp out. Ok, just, breathe... Put the flamethrower down. Dang thing wouldn't burn anyway, leaks too much...   Did you know the rotation of a round crank sensor in a round hole, matters? I do now. Took me about half hour to retrace steps and realize what I had done. Then it started right up.   No squeaks. The squeak was the old balancer.   Once it entered closed loop, fuel trims are dead on, hovering right around zero at idle. No more -30%. I'll credit the injector rebuild on that one.   Timing? I think there's an OBD 1.5 translation error with my Actron scanner. It's anywhere from -20 to -30 at idle, sometimes as high as -40 cruising. Sorry, the engine just isn't running that smoothly at -40 degrees ignition advance. It's just not. It's smooth all through the rev range and has decent power. I'm going to have to trust the seat of my pants on this one.   The new exhaust is very quiet. The old catalytic converter? Not melted, but definitely not healthy. Rains glitter when you turn it on its end...all the precious metal is flaking out. Once the new exhaust system burned in/smoked off a bit, the engine's exhaust smell is normal again. Not that I'd recommend going around huffing car exhaust, but, you know what I mean?   One problem to correct. The new exhaust has the opposite problem of the old spliced up exhaust. It wants to hit the floor where the old one wanted to rest on the cross member. Happy medium, please? Still noodling on that one, need to look at how I can adjust some hangers.   I don't know what's next. On one hand I want to run away from this thing as far and as fast as I can -- there have been a lot of NOT fun moments. On the other, now that it kinda drives nice, maybe drive it around for a little bit?   Shhh... it's not currently dripping oil all over the floor. I can see just a little wet at the bottom of the timing cover where it meets the oil pan seal. It's not dripping multiple drops with every ignition cycle, in fact, after some driving this evening it has yet to even form a drop that could drip off yet. But the weekend is young... I fully expect this could turn into Exxon Valdez by Sunday. Because this Blazer hates me. LOL.

      About that:   Once upon a time in a land far far away lived a car company that was shy about taking your money and wanted to be sure that they gave you more that you asked for so that you'd come back. No really, not a fairytale. 😱   But after the field got thinned out enough to limit the competition it seemed good enough to give you only what you asked for. Fair enough I say but in such a market you have to give something the others are not or they go to the one who does. Gimmicks or glitz. Oh, fins and chrome. Yea, shinny crow like cars. Yum.    Field narrows a bit more and 'brand loyalty' becomes a thing and the minute it does they start thinking to themselves, "Could we make more money if we gave them less than they expect and they will hang in there for brand and comfort with the known?" They gave it a try and da*n, it worked!!    Well, what if we teach them, groom them into believing that less is "Normal" and cut some more corners. Will that work? Oh heck yea!    🤔 I wonder, can we give then WAY less than they expect and make them mad enough to spit nails and STILL get them to pay up? Sure, if we get everyone else to do the same so that the choice is less or nothing at all. How would be do that? Platform sharing.  What a concept, right?  Steal like there is no tomorrow and it's legal too!    Truth is no one is going to give up driving, not for very long. The Gen Z crowd is fine with it and will be as long as someone not Gen Z will haul them around. At some point we all die.    Economic voting only works if you cast a NO vote now and again and enough of them to get dumb and dumber to wise up. Well, that's how I was taught anyway. And it should have worked. Would have worked. But the Bail out!!   Look, you have another choice if  you take that bag off your head. If the dumb it down to some predetermined expectation of how John Q Public will use it the, that is under design it to failure they you use it to a lower stress mode. D'ho!    A 1950 Royal Enfield Bullet 500 will go anywhere a Suzuki Hayabusa will and for just as long. But you will have to treat it for what it is and not for what you wish it was.
