2016 GM 3500HD Crew Cab 4x4 has intermittent violent front end shaking when braking.  I do NOT feel it in the peddle.  It starts intermittently, then progresses.

Repair history

6/8/17 - 22,890 Turned Rotors
9/25/17 - 29,752 New Rotors
12/11/17 - 36,282 Dealer says nothing wrong....it's was shaking when I brought it in but fine when I drove it home
1/11/18 - 36,833 Calipers sticking, bolt rubbing - replace rotors, shoes, calipers
7/19/18 - 48,764 Replaced rotors
8/2/18 - 49,540 Modulator valve found to be bad, turned rotors & new pads
9/13/19 - 74,560 more violent shaking. Appointment at dealer tomorrow

 

All work done under warranty using OE.

 

Each time I took it in for repair, I explained that I did not think it was a rotor issue because the issue is intermittent in the beginning.  Either there is rotor thickness variation or there isn't!  I have not towed my 5th wheel since around 10k miles although I do occasionally pull a 20' boat.  I am not a stop-go driver and don't ride my brakes.

 

I have an appointment tomorrow morning with the dealer.  Any idea what they should be inspecting?

You might want to consider contacting a rep from GM with that much service visit history and no resolution.

Are the rear brakes actually working correctly? Infrared temp gun aimed at all rotors after driving will give an indication of whats going on. Fronts normally hotter than rear, should be roughly even between both from wheels.

They have assured me on multiple occasions that the rear brakes are calibrated and working properly.  I asked about talking to a GM rep and was told that the district/area reps were eliminated several months ago....which I call BS.

 

What stumps me is the fact that the problem comes and goes then gets progressively worse.   

 

If it is not resolved, my next step will be to contact an attorney that specializes in NC Lemon Law.

      I have an unused GM Authorization code.

      By s10dragracer888 · Posted

      As the title suggests, I have an unused General Motors authorization code for a set of bed perimeter lighting lamps that I bought. My truck was built with the option for perimeter lighting, and they worked without programming… So now I just have this code. What is it good for now? Can anyone here use it?

      Some Assembly is Required

      By Grumpy Bear · Posted

      Missing pieces of the Assembly   Detergency vs Solvency   Not the same thing. Detergency is the mechanism that surrounds solid particulates preventing amalgamation. Usually accompanied by a Dispersant whose job it is to keep those encapsulated particles in Suspension. Solvency keeps things that can be dissolved in solution.    Salt is a solid that can be dissolved. Pepper is a solid that cannot be dissolved. A detergent/dispersant is effective on pepper but a solvent is more effective on salt. As long as the solids remain in either state, dissolved or dispersed then they can be be removed with the oil upon change.    How many wranglers does it take to herd cats? Depends on how many cats your herding. How much sponge does it take to soak up water? How much water is there to soak up? Point is most oil blends start with some herding ability and next to zero sponge and recently even fewer wranglers are being sent to do the same job.    So you start with a dozen cowboys and zero cows but at the drive progresses you pick up cows along the way, but not cowboys. At some point you have more cows that the wranglers can handle and some leave the herd. Deposits. And the API has an acceptable number of cows they are willing to let loose. In the ideal world zero is the right number for he rancher but to the butcher....a few lost is fine. This cow is beat to death. Let's move on....   Solvency isn't something oils on the Walmart shelf care about AT ALL. Problem is, you motor does. Fuels driven varnish sticks rings and only a solvent can keep them in check. The bet is that the solids driven portion that plug the expander rings and the oil drain backs and VVT screens and AFM screens will be an issue long before varnish is. Not that it wont be but if they market well enough the consumer can be kept ignorant enough to either believe it is "normal" (A quart in 1 or 2K is normal) OR is kept at bay longer than the first owner is likely to hang on to the unit. Solvency cost money.    Now the OEM's have John Q. Public buffaloed into the belief that the number cows accumulated along the trail is a known and predictable CONSTANT. It isn't. Nor is the rate at which they crossed paths with them. Only the number of wrangles is constant. Or was. Each new generation of oil sees fewer and fewer of them.    So what happens when the number of cowboys is lower (lower TBN) with each seasons trail but the trial is longer (OCI) and the number of cows along that trail continues increase? (Conditions that promote deposits).    For awhile the blenders were on to something. Better bases are harder to degrade (fewer cows) but that was overtaken by a longer trail (OCI) and improved breeding (More cows) while continuing to reduce the cowboy staffing levels (TBN/Aniline #).    Marketing has been successful. We've fired most of the staff, cows breed line bunnies, the trail is ten times longer and we've convinced the boss his ranch is in better shape that it ever was.    That kids is just the cleaning side. The side few pay attention to.
