So show it to the dealer not us , it's under warranty !!! Jessshhhh !!

 

Always road test with a shop foreman or service mangler for the intermittent concerns !!!!

Trying to be in the middle here but, govtech (can be uh...rough...like 60 grit rough) but he makes valid points, and the internet and this forum are not GM technicians, so don't expect much. That said, if the dealer has seen this, then they should have an understanding that something is wrong. If you have the ability, let them keep it and get it to act up, or if it acts up long enough, take it to them while its doing it.

 

I would imagine there is some sort of fault code being stored. Loss of communication or something. Could take a reprogram to fix, maybe a module replacement, heck, could be an intermittent ground issue. Got to let the dealer play with it. If you don't like the dealer you are with, try another or get in touch with one of the GM reps on this forum.

 

Good luck.

2015 Silverado we have spent more time and miles taking it to and from the dealer. This is the third time they can't find anything wrong.

Hi Awells32,

 

We are truly sorry to hear that you've had to multiple trips to the dealership for trouble with your new Silverado. I can certainly understand how disheartening this must be for you. We'd be glad to touch base with your dealership to ensure all resources have been utilized toward a resolution. Feel free to send me a PM here on the site with your VIN and contact info if we can be of any assistance!

The dealer said they would give us a new truck. Sounds good to me. Just wondering if that's legal for them to do or is it a way to stick me with two truck payments? I love the truck but never get to drive it.

We're sorry to hear this Awells32. If you would like for us to reach out to them for additional information, let us know. All we would need is for you to send us the requested info and the name of the dealership. I look forward to working with you.

Thank you GM representative. We want a new truck! We've been paying for this one and never get to drive it! I've bought 4 brand new Chevy trucks and never had these problems. Ive taken days off work and my wife has also. Our time is invaluable! Just to take this truck to the dealer! We paid for a brand new perfect truck, what happened was we took the truck in for this problem twice. Then the dealer put a dent in the front fender on the second time. Now this is the 4th time and no results. Now we have a borrowed truck for almost 3 weeks that we gotta drive. I'm pissed!

Awells - Educate your self and review the lemon laws for your state. Also contact the dealer zone rep. Be courteous and firm- clearly state your case. You catch more flys with honey than vinegar.

 

Good Luck

I am having the same issue! At the shop now they have no resolution and say they cannot duplicate. I took it to them with the issue happening. I have noticed it happens to me when it is night time or low light situations after about 20 minutes of driving. I thought it might be something with the ambient light sensor or a system that that is activated by it. I have a video as well I will try to get it uploaded.

 

I bought my truck 3 months ago it was used but with only 5900 miles on it. 2014 GMC 2500HD Duramax. it was certified pre-owned and retained the factory warranty.

 

Let me know what your current situation is and I will do so with mine. Obviously there is an issue.

Here is the video of mine I had to chop it down it was 17 mins long.

 

It began after driving approx. 20 mins.

      Gas fill door

      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.

      Active Grille Delete

      Hello from Australia Just sharing that there is now a way to delete the active shutters entirely with just a plug in module. Opens up tons of room to light bars etc.

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

      By jake111 · Posted

      I have an observation and a question... 1) I watch the voltage closely because I have had to dial in the cut-in/cut-out voltages of the battery separator to my camper.  The "smart" charging drives me nuts.  Anyway, I noticed that when coasting for a while, and especially if lightly using the brakes (though not necessary), the voltage goes up from mid/high-13 volts to mid/high-14 volts.  Then it drops back down after stopping or going again.  Consistently!   The only explanation I can come up with is REGENERATIVE BRAKING!  Well, maybe that's a little bit of an exaggeration, but it's certainly free extra battery charging.   2) Driving on mountain roads I will use L and vary the max gear.  Things straighten out and I end up in L10.  Sometimes I leave it there for a while.  Is there any difference between L10 and D?
