I'm watching this as well. I am disappointed with this issue, but suspect it is cosmetic, but I hate to wait and do nothing to be wrong.

Ok, I am new to this site but as a GM tech who has been pushed too far, its time the truth came out! I know for a fact in the northeast, there is a service bulletin #PI056E: and its titled wax coating

That's not acceptable! Looks like it was done by a blind man. I'd be back there demanding to know why they had the truck for 3 days and that's all they accomplished. I sincerely doubt it's GM's fault,

Well, now you see the GM manufacturing trend for these trucks. The idea is to produce a comfortable vehicle with a car like ride, silent interior, and loaded with gadgets. This is bound to impress t

I brought my 2014 Sierra in for service in January because of frame rust. I knew it was a joke when they said it would only be an hour before it was ready. Now two months later all of the rust is showing through again. I called GMC's complaint number, and they just connected me back to the dealership who said I could bring it back in to have it re-coated. My dealership is certainly not removing and treating the rust areas before applying the seal coat, just spraying it black and giving it back to the customer.

AND THAT'S THE WHOLE IDEA. DO A SHODDY JOB SO YOU DO NOT COME BACK.

I wonder if you can spray the rust spots with Iron X to remove it and save the hastle of using a wire brush to get rid of it: http://www.amazon.com/Carpro-Iron-Remover-500-Ml/dp/B004UM6DLE

 

Then just spray the 3M rubberized coating over these areas after washing the Ironx X off. I used Iron X to get rid of rail dust on the body of my truck but I also sprayed it on a rust spot on a steel door on my house and it removed all of the rust from that spot.

 

EDIT: The product description does say:

 

  • Iron X should not be used on chrome, bare metal parts, brake calipers, wheel balancing weights, or SMART paint repairs

So I dunno.......

Started to notice rust on my frame lately as its spring and I'm starting to wash and clean my truck more often. It seems to be mostly on areas where it was welded. I don't even know if its worth the hassle of trying to get the dealership to fix it. They will likely just say it's because of the salt from the winter.

 

Just another thought, I don't really care so much if the rust is only cosmetic and won't cause issues in the future. That being said, where I can see my frame in the rear wheel well is rusted, has anyone considered using a bedliner materials to cover just that area?

Mine is getting worse and it’s very frustrating – especially when you see Sierras and Silverados without this problem. Whenever I see someone’s 2014 or 2015 the first thing I do is check out the frame in the rear wheel well. I’ve contemplated taking it up with the dealer and bringing up the bulletin, but do I really want them taking off the box etc? I thought about giving the problem areas a shot of black Rustoleum or something, but this might make what’s left of the coating come off even faster. Hopefully this is just cosmetic. Regardless, it’s not a good feeling paying 50,000 for a vehicle and experiencing this issue on something that’s not even a year old. I guess it doesn’t hurt to try the dealer route and see what they say. In the meantime, have you thought about trying the plastic GM Wheel House Liners? I’m not sure if they go that far down to cover the frame but it might be worth it to look into..

That is 5 attempts to cover the rust and making it worse every time, I have rustproof over spray from running boards, to paint, tailgate, back chrome bumper, wheels, exhaust tip etc... and is falling off really bad.

mrp, that rusted bolt on a '14 does not look good! That is fast rusting. I live in south, so we don't have so much of a rust issue, but we still have rust. I hate rust on my trucks. I bought a used '93 Dakota in '97 with 47,000 miles from Ohio. It was treated by previous owner with that Ziebart stuff - WOW - it works!! I still have that Dakota with not a bit of rust! Love it.

I have been using fluid film to protect against rust and so far so good. I had a 5x5" spot where the wax didnt seem to be bonded to the metal. Painted with flat black paint and reapplied FF. I've been reapplying every 6 months or so. Not for everybody but works for me.

Is the fluid film softening the wax on your truck or not?? I would like to know because this is why I haven't put it on the wax. I have only been putting it bolts and nuts that need to be removed for maintenance, brake line ends/connections/bleeders, forged steel parts, tie rods, etc.

It made it slightly softer but never lost adhesion. Just one spot in the rear wheel well that looed suspicious before I even started putting FF on it. I'm not concerned about the wax. Every GM truck I have seen in person with this wax is begins to harden and crack, exposing the steel. Or water finds a bad spot in the wax that isn't visible and rust spreads under the wax. Last summer, while putting on my exhaust, I noticed that the sharp edges of all the drain holes on the bottom of the frame had wax that was peeling back and rust had started to spread underneath.

 

 

To be honest I wish the wax wasn't there at all because I would have been painting it with POR 15 and would never have to worry about it again.

Hi Guys, I just picked up one of the last 2014 Chevy Silverado's at my local dealer. The build date was Jan of 2014 and I noticed rust on the frame exactly like everyone in this post. After complaining to the dealer and sending info over regarding the TSB you all referenced GM will be completely removing the frame and re-coating it. I'm a little nervous that they will never get it back together properly, Has anyone else had this done? How long did it take? Any issues?

 

Thanks

      Some Assembly is Required

      By Grumpy Bear · Posted

      Can it still be Assembled I?    Stribeck says that we need a certain amount of viscosity under conditions of load and velocity to prevent two surfaces of a know roughness from tearing each other asunder. And we have marketing trying to tell the masses that those two surfaced require less of that commodity due to more exact limits being placed on the same old clearances. We also know that there are limits to how hard something can before it becomes to brittle to be viable and to smooth to 'wet' the surface and that both of those conditions have been known and met since about the Second World War.    That viscosity value shook out at 10 centistokes at 212 F just under a hundred years ago.  Give this a look: [Anton Parr]     What is advertised is the Kinematic viscosity (mm2/s) or that which has been density adjusted but the value we are after is the dynamic viscosity (mPa.s) or true viscosity. You can see that this number is dependent on density thus base stock and temperature. You can also see that an SAE 30 doesn't reach that value in this example. However an SAE 30 that is at the upper end of the SAE 30 range; 12.5 cSt (mm2/s), might. 12.5 * .83 = 10.375 (mm2/s). If you could find an SAE 30 at the upper end these days.   Then there is the complication of viscosity modifiers or VII or VM, whatever you wish to call them. Polymers added to very thin base oils, perhaps 3 to 6 cP oils, that will meet the SAE *W30 spec at 'tested' shear rates and 100 C/212F  target temperature. So a polymer fortified base that is a fraction of the 10 cP requirement Stribeck insist upon.   This could be all well and good if those polymers didn't have two very problematic 'features'. They shear or loose viscosity both 1.) permanently and 2.) temporality. And they do both omitted in the advertised data with the distinct  purpose of deceiving the consumer of the actual operating state of the fluid. I've shown the example of Warren Oils COSTCO 10.91 cSt 5W30 formuation several times where the 100 C HTHS value is 6.9 cP!! That's the temporary shear down and with and SSI or shear stability index of 9.4 cSt. Note the intentional deception in using mixed units?    After a short while that 9.4 cSt oil has a viscosity corrected dynamic value of 7.8 cP. But as the SSI is still within the range of an SAE *W30 whose lower value is 9.3 cSt.    This allows them to continue to call this SAE 16 weight oil a 30 weight, the cake, and still meet the API requirements for fuel efficiency IMPROVEMENT mandated by the EPA. The eating of the cake. By the time you've worn out your motor doing the responsible thing by adhering to the warranty requirements, (the stick), you get deprived of the carrot, wear control. So sad, to bad.   So what can be done? Do I need actually say? [Anton Parr]       Even this must be monitored if the oil is on the low side and the VII an organic or you opt for a 0W40 with an even lighter base oil and more / higher MW VII. (Note the lower density of the 40 weight versus the SAE 30 mono-weight?)    There is another workaround. Temperature. An SAE *W30 run at a bulk temperature of between 180 and 195 F.    Being the belt and suspenders sort I am I do both. Run it cook and run it heavy.    In Part II I'll work the AW package.

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

      By Atlas · Posted

      So, do I go elbow-deep on this thing or list it for sale and play dumb? Seems to "runs good."   I'm about $1200 away from having: -a rebuilt injector ($300) -a new cat ($250) -a new cat back exhaust (OE style) ($300) -a new AC compressor ($200) -AC refrigerant charge ($150)   In theory, this should rectify the obvious detracting issues from its value and operability. Cold AC with a non-squeaking AC pulley both sounds and feels good. An exhaust that isn't cut/hacked in 17 different places and doesn't vibrate on a crossmember would make it sound and feel less janky. A working cat would help the stink, and will save the earth, but *if and only if* the fuel system is working properly, which would also address the intermittent "rich" CEL.   Heard a good one... CEL for "Rich condition" means you haven't spent enough money on the truck lately, and it's letting you know.   Rebuilding the injector would seem to be the most important part. Replacing the cat would be secondary. I don't think mine is plugged or overly restricted, but it might be a little restricted? I have no good way to tell other than seat of the pants feel. I hate the smell.   The current theory is I have a rich idle problem: A bad fuel pressure regulator, or a leaking injector(s) being the highest probabilities. I already replaced the FPR but that doesn't mean its replacement isn't also bad. It was a new part from Dorman, but the packaging looked like it had been sitting on a shelf for 20 years.   This is the (single) upstream O2 sensor shown at idle. I'm getting a lot of "rich" it seems. Sometimes it stays high like that and doesn't drop down. That makes me think it's processing injector leaks or a partially stuck open injector.     Other times it looks like this. Nice oscillations between rich and lean, which is what I think it should be. Under load and at speed, the oscillations are nice and tight and uniform looking, high and low.     Fuel trims suggest the PCM is compensating pretty hard at idle to pull fuel out. But it's not enough to trip a CEL. Something about slowing to a stop: brake vaccum booster, EGR, or the EVAP purge is delayed, or there's pooled fuel in the intake again that's draining into a cylinder is enough to set the CEL. Of course, in two days of driving, it hasn't set. I was hoping to actually look at the freeze-frame data when it sets. IAT is high because it's idling on an 83 degree day here.

      Gasser Subforum Has Been Quiet - - So, Regenerative Braking and Using L10

      Common failure.  You need to replace the fuel door housing.   The painted cover transfers over to the new housing.  To remove the old one there is 4 spots where you poke the plastic to release it.

      Gasser Subforum Has Been Quiet - - So, Regenerative Braking and Using L10

      By newdude · Posted

      No such thing as regenerative braking on a pure ICE vehicle.     Regenerative braking is the re-capture of energy from electric motors and stores it in the battery pack.  So hybrids, PHEV and EVs have regenerative braking.     What you are seeing is the charging system changing modes is all.  Its likely entering charge mode for some sort of reason is all.  All of the charging modes will be listed below.   As for L10 vs D.  L10 turns off automatic grade braking.  L10 puts you in control of grade downshifts where in D it will automatically do it based on brake pedal position and other factors.  Otherwise L10 and D drive exactly the same aside from that one aspect.    Battery Sulfation Mode The BCM will enter this mode when the interpreted Generator output voltage is less than 13.2 V for 45 minutes. When this condition exists the BCM will enter Charge Mode for 2–3 minutes. The BCM will then determine which mode to enter depending on voltage requirements.   Charge Mode The BCM will enter Charge Mode when ever one of the following conditions are met:   Windshield wipers are ON for more than 3 s. Climate Control Voltage Boost Mode Request is true, as sensed by the HVAC control module via serial data. High speed cooling fan, rear defogger, and HVAC high speed blower operation can cause the BCM to enter the Charge Mode. The estimated battery temperature is less than 0°C (32°F). Battery State of Charge is less than 80%. Vehicle speed is greater than 145 km/h (90 mph) A current sensor malfunction exists. System voltage is determined to be below 12.56 V When any one of these conditions is met, the system will set targeted generator output voltage to a charging voltage between 13.9–15.5 V, depending on the battery state of charge and estimated battery temperature.   Fuel Economy Mode The BCM will enter Fuel Economy Mode when the estimated battery temperature is at least 0°C (32°F) but less than or equal to 80°C (176°F), the calculated battery current is less than 15 A and greater than −8 A, and the battery state-of-charge is greater than or equal to 80%. Its targeted generator output voltage is the open circuit voltage of the battery and can be between 12.5–13.1 V. When fuel economy mode is active, the generator is not charging, only maintaining open circuit battery voltage. The BCM will exit this mode and enter Charge Mode when any of the conditions described above are present.   Headlamp Mode The BCM will enter Headlamp Mode when ever the head lamps are ON (high or low beams). Voltage will be regulated between 13.9–14.5 V.   Start Up Mode When the engine is started the BCM sets a targeted generator output voltage of 14.5 V for 30 s.   Tow/Haul Mode (if applicable) Pressing the Tow/Haul Mode button located on the center stack, the vehicle system voltage is raised and the remote (non-vehicle) battery will be charged. Having the headlamps on will raise the system voltage and if the Tow/Haul button is applied it will not serve any purpose. The voltage is regulated between 13.9-14.5 V.
