Did this ever get solved? I'm chasing 2021 Yukon Denali electrical issues - vehicle will not enter sleep mode - we can disconnect and reconnect the battery and it will sleep - but that's likely because we powered down whatever module doesn't correctly sleep. once we start/accessory the vehicle and turn off, it will stay at 11.5 amp draw with something keeping the SDGM alive - it appears to be activity on the X2 segment, specifically CAN FD Bus 5 - but we don't know which device and we think we've already isolated all of the devices on that segment - so what keeps the BCM and/or the SDGM alive is unknown. I don't yet have a packet trace from CAN 5 (and since this Global B we might not get much info from it) - but the vehicle has been down for 8 weeks and previously GMC Dealer was unable to resolve "kills battery" issues with this particular vehicle - so I'm at a loss - it seems to be beyond local repair capabilities - and the number of "telematics keeps vehicle from sleeping" posts indicates this whole architecture has major issues - I hate to say it, but we might have to install a battery cutoff switch on the front grill - one of those red boat switches - to turn off the vehicle.;) Any pointers appreciated;) I just bought a CAN FD interface and I'm planning to try Savvycan and Peak Can SW to triage this further.
Have had this truck for 7 years and it has 135,000 km on it. Have had no issues with it. Had 70,000 km when I bought it so I average about 9300km/year. The other day I started it to leave grocery store and felt a bad miss as I was pulling out of my stall. Rolled down window and heard the clatter. Limped it home about 1 mile and investigated further. Cylinder 6 misfire, check engine light flashing and I believe traction control light on. The flattering gave it away in my mind. I did try swapping plug, coil and wire from 6 to 4 hoping the moss would move to 4 but no luck. Also compression dropped to 120lb when cylinder 1 has over 200lbs. Called tow truck to tow to local GM dealer. Failed lifter and 1 bent pushrod. Dealer changing lifters and pushrods on 2,4,6,8 and also VLOM. Think it may be time to get rid of this truck when I pick it back up from dealer. Dealer told me they do about 2 of these repairs every month.
Yes, but the disablers for '22.5 and newer weren't available for a long time after '23. And then only by Range.
This is the first I've heard of another company offering one. Just want to confirm it's a fact.
Nice!
That would take years off my life keeping them that clean up here in MA. Between the rain and road salt, besides all the potholes that stay full of water, it never stops.
