I hear you. Let me know what they say. I hate to lose work time and have mine back at the dealer less than a week after I bought it but it’s getting to that point. After I posted, it must have did it another 20 times when I went to lunch and I’m just annoyed as can be. I messaged the dealer to see if they have any inside knowledge on the problem. I’d be more encouraged to take it in if everyone on this thread who brought there’s in didn’t continue to have the issue.

Same issue here. Less than 600 miles on 2019 1500. It's at the dealer for the second time in less than three weeks (2 of those weeks it wasn't driven). Took it out in the snow five blocks to grab a bi

Add me to the list of those with these errors codes.  Extreme cold is causing it.  I am in MD and this is the first time it has been below 15 degrees since I bought the vehicle.

This is my second time in to dealership for it first time I think they just checked for error codes etc and said they reset some things but didn’t find anything glaring.  I’ll keep you posted what they say tomorrow.  Also just ran out to do some errands and it’s 15 out it did the errors for first 5-10 minutes in the car then stopped for a bit but then came back again.  Pretty inconsistent and the truck is clean so no sensor imparement.

I'll be taking mine in for the second time at the end of the week. They did the same with mine the first time, and they found no errors.

We will see how it goes this time.

Let's all keep posting in here with updates if we can. Any info helps that we can pass along to each other.

Thanks

Just got a call from the service advisor. He said the GM engineers are still trying to figure out if this is a hardware issue, software issue or both. He said it could be weeks to months before a solution is identified but that it is a known issue and they are working on it.

I filled out an online safety complaint with the NHTSA after the distraction almost caused me to read end someone. I hope if others do the same GM won’t be able to just ignore this thing for a few months. 

 

On the clean/dirty sensor thing...

 

Today I drove over Teton pass... heavy wet snow. Incredibly bad conditions. Some of the worst I have driven through in a couple years. 

 

The truck was fantastic, the tranny did exactly the same ‘holding gears and soft up shifting’ to hold downhill speed as I would have done with a manual. I haven’t had a trans that doesn’t slam gears with a manual up shift when the rpms are high during grade holding before this one. Truly impressive.

 

Front wheel drive cars in the uphill lane headed towards Jackson couldn’t even get up the grade due to ice. (I hope they like their ticket for ignoring the 4x4/chains conditions in effect signs). The trucks was totally composed through it all mostly around 20-30mph. 

 

Anyways, back on topic. After 200 miles in heavy freezing slush my truck was encased in tons of ice. The running boards were full to the bottom of the doors (might be a design issue there— at least something to watch for). The sensors front and rear had at least a half inch of ice. Putting the truck in gear made it pretty unhappy for a bit with the buzzing seat until I got moving. 

 

All that time though the trailer thing did not go off. To me this means the issue is strictly the trailer connection system and not the parking sensors. The alerts about disabled parking sensors and rear traffic are probably just what it does when it thinks there is a trailer connected.

Yup, I think you’re right on the money and I will also fill out a complaint. I’ve noticed similar things...I had my truck out in a blizzard a few days ago, parking sensors covered in snow and ice, did not have the issue. Today the truck was pretty clean, but it was much colder, and the error was happening non stop. I wiped the sensors off and it still persisted until it got above 20 degrees outside. Almost everyone on here talks about the issue at below 20 degrees. There is something to it, and it’s temperature related, not snow or dirt on sensors.

I am thinking the same.

That being said, I've had lane keep assist and lane change alerts cycle on and off as well. Both would not be affected by a trailer being hooked up.

So the stuff at the back of the truck, I do think you are correct.

“LCA is disabled when the trailer connection status is displayed. A DIC message may display. The SBZA system still operates.”

 

I’ve haven’t had the lane keep assist fail yet, but the LCA and the trailering features are definitely connected, and I think the trailer problem is taking out the LCA and causing the two errors, one after another.

Same issue here. Less than 600 miles on 2019 1500. It's at the dealer for the second time in less than three weeks (2 of those weeks it wasn't driven). Took it out in the snow five blocks to grab a bite and on the way back home constant trailer disconnected messages on the dash. Dealer told me today it was water/moisture in the sensor again and I would just have to deal with it until GM has a fix. Calmly told them that was unacceptable and I would pick the truck up when it was resolved or they can take it back.

like the truck but man this is just bad for a brand new model. And to say it’s moisture and temps is so typical dealership bs all they care about is selling the car.  They need to be our advocate here and get it fixed and communicate it to the owners.

They contacted GM and are waiting for them to respond. Hopefull will have an update tomorrow sometime. After reading these posts I am not real optimistic

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

      By jake111 · Posted

      Thanks newdude!  By the time manual selection is needed, I'm probably too much of a control-freak to depend on the transmission sensing braking to activate automatic downshifting.  I would be anticipating the situation and already be manually downshifting.   This truck replaced a 2004.5 LLY diesel with the Allison 5-speed.  Putting it in T/H made noticeable differences (when the torque converter locked, upshift points, downshift behavior).  On this 2024 gasser with the 10L1000 I haven't been able to detect much, if any, difference.  Ok, I can never tell now when the torque converter locks up.  But I also don't notice differences in shifting.  For downhills, I've probably already manually downshifted by then anyway.  Since it's also more awkward (than the 2004.5) to engage/disengage I don't even bother.  Or maybe it doesn't really matter with just a 3k lb. camper in the bed?   Thanks also for the list of reasons the charging system might select various voltages.  However, what I am seeing doesn't fall into any of those categories.  It very definitely, and very consistently, rises after coasting/braking.  Maybe not immediately, but not very long after coasting/braking.  Very consistently drops voltage when no longer coasting/braking.  It might also be interacting with the camper battery charging (I might disconnect the camper and see if it changes the charging behavior).  I also need to recheck turning on headlights for when I want to force it to charge the camper.   Another JR, in June I converted the camper to LiFePO4.  Since it's not a good idea to try to charge lithiums directly using truck, I installed a Victron Orion XS DC-DC charger (which BTW is AMAZING!!).  Being cheap, I only had to buy that one item (besides the battery, of course) to do the conversion.  The camper OEM 120v battery charger (only 19 years old and works perfectly) and the truck feed the input to the DC-DC charger (not at the same time).  But I didn't want the camper charger feeding back to the truck so I kept the old separator.  I considered replacing the separator with a 30amp diode but that means more work and might add another 1/2 volt drop.  One thing that surprised me was the voltage drop over the long 10awg wire run, so I can only charge smoothly at 8 amps (because the DC-DC charger is completely configurable).  Another reason I don't want an added voltage drop with the diode.  I might also be a little lazy but all this work is being done under the sink with a small cabinet opening.

      cam upgrade in CA

      By davester · Posted

      apparently CA smog is (or at least was)  checking that the vehicle is using the oem and/or a ca smog approved tune, so I expect you'll fail inspection doing it.

      yes, leaking exhaust will mess up o2 sensor readings, which in turn messes up fuel trims.

      286,740 Mile Services   8/6/2026   New AC Compressor. Refrigerant oil and dye, evacuate and charge system.  New exhaust system from cat back.  New Iridium plugs plus replace #3 coil Repair/rewire headlamp wiring (passenger side) and replace all forward bulbs. Polish lenses of both assemblies.  Pull rear rotors, clean and adjust parking assembly. Inspect, clean and grease front calipers. Check pads and shoes.  4 wheel power bleed of brake system. Dot 4 Reset idle speed 50 rpm higher New Serpentine belt.    Will need new pads in the rear in about 5K more miles.    Tax Title and License out the door just short of a grand.    AC clutch had bitten the dust. 1 year warranty on the pick and save replacement. Thing will make a Polar Bear cry Uncle.  He spent quite some time on the wiring. It was in the harness and he does nothing half. I got off cheap. I have considerable more light down the road. Sylvania Silver Star replacements.  Gas seal between the porcelain and shell of plug #3 was blown, cooked the coil. That was the cold miss.  Love the new exhaust. I can sneak into the neighborhood again.  Nice to have a working parking brake again. Belle Tire never got it done. That was disappointing.    This was one of her bigger bills and still way cheaper than a payment even given the oil consumption. This thing cost me under a hundred a month in repairs and normal routine costs. What is my incentive to replace it? 🤔
