2020 1500 RST 5.3L 1700 miles

So after a few errands this morning, I hit the highway.  Merged on the the Atlantic City Expressway and checked the mirror.  Lots of smoke.  Other driver pulled up and said I was dumping fluid.  Pulled off to the shoulder and the fluid was POURING out of the front.  Looked like somewhere up by the radiator.  I wasn't looking forward to crawling around the truck on a 75+MPH highway.  Towed it back and waiting to hear from the dealer.  So much junk up there that I couldn't tell where is was coming from and didn't know how much I lost to start it up and find out.  I'll report back in a few days when I hear what happened.  Just wanted to get a little warning out there

Trans cooler line maybe? Certainly not unheard of but very unfortunate on a new truck.

Almost certainly that.  Just don't know if it was a loose fitting, split hose, no clamp, etc.  PIssed that it is all over the engine bay and underside of the truck.  Anyone want to put some action down on whether it gets properly cleaned?  Not to mention they said that warranty people don't always cover 100% of the tow bill.  That's gonna be a fun argument if it happens.

Add towing to your auto insurance.

Probably one of those new snap fit connectors. Great development for fast robot assisted assembly; not so great for owners if one of those nylon connectors or neoprene "O" rings give out. Even use them on gas lines and the high pressure A/C lines.

It seems to be a growing trend these days, never had issues like we see now with remote lines either trans or engine coming undone like this. Leak yes, but completely blow out and dump everything out , not that i can remember.

GM covers the tow under warranty as long as you called them to get it towed idk about calling the dealership or another tow service though, I wouldn’t pay a dime on towing. Sorry to hear about that hopefully gets fixed properly.

Yeah GM roadside assistance is free as long as you are within your warranty.

      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.

      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?
