Let me know how long it takes for you to get it fixed... mine is still at the dealer as it as been for 5 months

 

And your dealer is waiting for the new oil line and taking 5 months?

I've spoken to a good friend who is a 30 + year tech at a North Jersey Chevrolet dealer. So far he has seen two '19 Silverados with blown oil cooler hoses. He said to look for a yellow witness stripe

Jesus Christ man. What is going on with Chevy? Failing oil lines, water leaks, software issues? You'd think they were BMW, and not good old reliable Chevy. I'm a BMW tech btw, and our quality has gon

sounds like the best thing to do is run it until the engine seizes up.

I heard that they're re engineering the part and don't know when it will be fixed

Ya , very well could be. id  Be asking again. I was the orginator iof this thread and after mine first blew I thought it would be fine with a replacement part. About 8-9 months after the replacement line was installed I got a recall

letter saying they would replace the defective line again.  I asked service manager and they replaced it with the same line that was from the faulty place to begin with so it could of  happened again.you assume the new peice they put on wont be defective again.  Always been a gm guy but these new 19-20 trucks are something special. At least my dealership was good with the constant breakdowns and giving me a loaner.

How long did it take you to get the part? 5 months is way too long

Craziest thing I have heard on these forms yet, you've been waiting for 5 months this is where a lawyer gets involved and you get your money back

5 months to get an oil cooler line? Something doesn't add up here. You can go online and get one sent to you in a couple of days.

Is this an issue with the 6.2 or just the 5.3L oil cooler lines?

I had one go on a 6.2. Luckily I shut the truck down immediately before I ran it out of oil

Well, add me to the list of guys who have had the engine oil cooler line fail.  2019 AT4 5.3 with 6200 miles. I had just pulled onto major roadway and got up to speed when my alarms sounded and dash read "low oil pressure, shut off engine immediately". As soon as I saw that it was an instant pull over and shut down.

 

25 minutes for G.M. roadside tow to arrive. Truck now at dealer to be repaired. Whole line came out of crimp! W.T.F.

Worst part with this is it has been happening for decades now, GM has always had issues with crimped oil lines coming undone and they seem to do not very much about it either.

Truck back. Dealer had line in stock. Service dept told me it still had approx: 3 qts of oil in the pan.  I think I got lucky being able to shut it down fast.

      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?
