I keep rewriting this because for some reason it keeps timing out everytime I look for the video to attach. I brought the car to taska twice for underhood fire and ignition. No head gasket got fixed no spark plugs there is several issues water keeps getting in tires are rotted electrical problems and now head gasket is messed up because the hood wasn't put on till afterwards for the recall the ignition is still not fixed. Last time I drove it back it stalled out and smelled over heated
NHTSA complaint #11730812 — an unverified report by a vehicle owner.
The cable harness in question runs from the fuse box under hood through firewall to the passenger side foot area. At this point it connects to another harness that connects to various items at the rear of the vehicle. One circuit in particular the rear window defogger is burning wiring and socket and plug of the two wiring harness. Either the wiring or connectors burned apart without the circuit fuse blowing. The circuit has a 40amp fuse. The wiring harness for this circuit is 12 Garage. I can't find any manufacturer who recommends using 12 gauge wire on a 40 Amp circuit. This isn't even close to being correct. This is so agreegessly out of specification it would appear GM knew they had an issue with the circuit and fixed it By over fusing the circuit. This same issue on multiple models over several years.

I am having issues with my engine unintentionally turning off because of my ignition key and I sent it to the shop for recall repair but they said they didn’t have the part and couldn’t find it because it’s not available.

These issues have been spotadic since I aquired the vehicle in october of 2021. Not infrequently the ABS system feels like it is trying to engage at low speeds with light braking such as in a parking lot. This also happens after coasting(no gas, no brake no cruise control))and then accelerating The radio will randomly stop playing or begin playing. The turn signal indicator chimes randomly stop chiming when the turn signal is in use though the interioir indicator light will flash normally. I have not been able to stop when this occurs with the turn signal still active to get out and verify it the turn signal is actually working At random times a loud clacking sound will come from behind the dash in the general vicinity of the radio and there will be no out put from the dash vents until the clacking stops. The use of any controls whether radio or climate does not seem to cause this nor will it stop it. Actuator doorb and/or solenoid perhaps?
