New here. I have a 2017 Yukon with 118,000 miles. About a month ago, the electronics have been going crazy. The Stabilitrak light comes on, the vehicle hard shifts, the tach, speedo, and other gauges other than fuel and battery just bounce up and down like crazy. When put in reverse, the camera shows but says “rear vision system unavailable.” I lose power steering briefly. Check engine light comes on and throws code U0073 - control module communication bus off. This always happens until the engine is warm. Then it runs fine. The lane assist has quit working all together.
I took it to my mechanic, who seems to know what he’s doing, can’t figure it out. He said since it’s all electronic, he thinks it’s a power issue. He replaced the battery but it has done nothing. ANY help is appreciated before I have to take this to GM.
