Shake or Vibration Issues

[Vic15]

Are the Denali's super adjusting 1,000 times a second shocks quelling any of the vibration issues or are the Denali trucks experiencing the vibrations as well?

There's not a single automaker out there that doesn't look at it this very same way.

GM looked the same way at the ignition switches and over twenty people died as a result. Does that make it acceptable?

No. If anything the Denali magneride is worse.

 

Every vibration has and equal and opposite vibration?

Quick update. Truck number 2 (my 2014 was BBB'd and MSRP traded for 2015).

 

After final repair and no fix, my GM business resource contact called within a week offering me basically anything I asked for. I could pick between full MSRP trade or repurchase. I chose repurchase...done with this mess. I'm not saying other trucks are perfect...but I cannot continue this cycle of dealing with trucks that are proven to be built with faulty parts, vibrate on the highway, etc...I have to move on and give another OEM a shot.

 

All in all I drove 2 new trucks for a total of 25,000 miles, and will be losing around $2k total after lemon law usage fees, for mileage before first service visit on the 2015. That's about $80 a month on a 2 year lease, pretty sweet. Mix in the frustration, and we can call it even.

 

This may be my last post here, so I would just like to say...for those still dealing with this issue, and want out, the BBB works. It has worked twice now for me. Keep all service records, be calm and cool with your dealership, as well as with any GM reps you have to speak with. The squeaky wheel gets the grease...post YouTube videos under an account with your real name...GM monitors these things and will make note of who is keeping quiet, and who is driving business away from them via social media. The more noise you make, the easier it will be for GM to give you what you want, especially if you want your money back (my theory).

 

GM was very difficult the first time around. They made multiple terrible offers before finally (the day before our arbitration date) giving in and offering full MSRP replacement. The second time around, I made as much noise as possible on Facebook, Twitter, YouTube, etc...and within a few days of my final repair they were already offering me full MSRP or a repurchase.

luck to all, I am moving on.

Well come back and post up what you purchased as replacement.

Glad it's settled for you.

Just out of curiosity I did a little Googling to see if the new F-150 might be having similar problems. And, it appears that indeed it does. (Open below url) So, do your homework before you trade for another brand. Just saying.....

Boy the Ford site sounds familiar!

"Boy the Ford site sounds familiar!"

 

Sure does. I'm wondering, all the truck manufacturers are in competition to try to build ever more rigid, rattle free frames and bodies. Because these bodies are now so tight, wonder if that may be the cause of this new vibration phenomenon? I haven't researched Ram but Ford and GM both appear to have similar problems.

I was talking to a buddy who own a body shop, he ran on for a ford dealer for 14 years... he says don't buy a ford, they dont stand behind their work.... sounds familiar huh? he says get a Toyota if we want something that wont have any problems.... or get a Ram

It's when the motor switches to v4 mode. Watch the display on the dash. Mine has the slightest shudder or vibration when cruising, low rpm. I manually lock the Trans in 5th gear around town, which keeps engine in v8 mode and problem is solved. Still does it in 6th gear around 50 or 60 mph

It appears not as bad as GM. Only 119 replies and 17544 views.

Umm, appears that the GM replies are about the same ole 100 people who've posted about 175 times On a serious note though, it's obvious that there's a very vocal small minority that's trying very hard to elevate this issue. I'm not convinced their motives are pure. Just saying....

Well I've now had 2 vibrators, and others have also had more than one. Vocal, yes, $50K+ trucks you can't drive would make you vocal also. It's also now been 3 YEARS and no fix on the horizon.

There will be a quick fix on the horizon if you quit buying these vehicles.

A few days (weeks?) back I tried some rear spring clamps to help alleviate the issue. It helped, but only temporarily. The shake came back once the springs settled (30 miles?)

 

Today I tried a large clamp (Autozone - 6 inch? $3) about 5 inches from the front of the driveshaft. I put the screw clamp opposite the large counterweight on drive shaft.

 

Could be in my head but seems to have helped significantly.

 

Going to continue down this path to see where it leads.
