I know this is somewhat of an aged thread, but I'm wondering if anyone has had success getting the STL files for this design? It seems perfect for what I'm trying to do on my headliner. I DM'd the OP but haven't received any feedback. Thanks to anyone who can help me out!

I had similar issues come up when I first bought my 2020 1500 LT LM2. Initially the dealer replaced a set of my brake pads and reset the monitor. After that I noticed significant reduction in breaking performance, almost like the brake booster is dying. Took it back in immediately and they tried to sell me new rotors, pads, and calipers, which wouldn't be covered under warranty even though the truck only had ~28k miles on it. I basically told them to pound sand and took my truck back. After about another 2,000 miles the other set of brake pads went from 88% down to 10%. Took the truck back to the dealer and they told me there wasn't an issue and they just disabled the brake wear indicator system. Definitely not satisfying answers across the board. Thoroughly disappointed in GM at this point.

I had this issue with my 2020 LM2, took it to the dealer several times. They performed some sort of TSB(software update I believe), that didn't seem to really do much initially. They then read me another TSB description which basically said that there are tank level ranges that seem to have this issue and the level will fluctuate for a short period of time until the tank level moves out of that problematic range. I didn't really think that was a good answer, but the issue seemed to correct itself after about 1,000 miles. I'm currently at ~40k miles, but the issue started to creep up around 30k. I would go back and press them regarding a possible software update to address the issue.

This happens to my 2020 1500 LT LM2, but seems to only happen when I remote start the truck. I've talked with Onstar on several occasions, but they don't seem to have a permanent fix asside from turning off the truck, open/close the door, lock the truck using the key fob and wait for 2 minutes to restart. Comes back on every time. Crazy that this bug still exists...
