Vehicle's electrical system will fail while driving, it may fail during ignition, and it may fail immediately after shutdown. These failures are catastrophic. All systems in the vehicle fail at once. All steering and braking assistance, all lights, HVAC, ignition, fuel delivery, all electrical systems are affected by this dysfunction. This is highly dangerous as it can and does occur while driving at highway as well as residential speeds. Associated failures include various dash modules unresponsive or off intermittently, stabilitrac service message, action needed message: Roll down then up driver window, exterior and interior lighting including headlights flickering and dimming, frozen or glitched or otherwise unresponsive radio, steering wheel forcefully jerking without input from driver or road, 'traction off' indicators. All issues are sporadic, chronic, and debilitating. Vehicle has delivered stabilitrak messages and momentarily tripped all electronics while driving as well. Not every failure is complete, some glitches in the electrical may persistently occur under normal driving conditions, this puts un due strain on the attention, mindfulness, and peace a driver is reasonably expected to achieve in any vehicle. This has also been a precursor to complete failure and great care must be taken to remove the vehicle from roadways and traffic.

Happens 3-4 a week when driving: I turn turn signal on and headlights flicker truck feels like losses power, if making a U-turn steering wheel gets hard and truck feels like stalling out. On highway going 65mph stabilitrak light flashed twice and truck felt sluggish very brief. When exiting highway and turning onto city street at 30mph very briefly the truck lost power and steering was like stuck, almost caused accident, truck felt like it turned off and on and jolted forward very hard and went back to normal. When I pulled into a parking lot the stabilitrak light came back on and truck stalled briefly again while turning at 15mph, all dash lights came on and power steering lost, truck went back to normal on its own.

This has happened several times on a 2014 Chevy Silverado I bought Apr 2020. The first time was Sep 2020 and diagnosis from the mechanic showed nothing found. Only showed error code that communication with the computer was lost. Code was cleared and it did not do it again until 2 Mar 2021. Upon initial ignition, the message window read "action needed. Roll driver window down and back up, I did this and then it went away. After driving on a flat, paved, dry road at about 35 mph. For no apparent reason, my truck displayed a message that said "stability control", the engine reved, rpms shot up to 5K and instrument cluster flicker several times, radio turned off and then returned to normal. A short time later at a light and the message appeared again, the radio and cluster completely shut off and then the truck suddenly died. I put it in park, and it restarted immediately, only to do it again (started again as well). The first two times this happened, the truck came back on without issue and I was able to safely pull over into a parking lot. It happened again within minutes of the second time and I had just pulled into a parking lot. This time, the truck completely died (no electricity, no ability to use blinkers, hazards, no power steering or brakes ect. Complete outage. After 10 minutes of it not coming on or starting, I called aaa to tow it and while on the phone (approx 30 minutes, it came back to life on its own (radio, instrument panel came on) and it started. I tried to drive it home, and at one light, it died again but restarted and I was able to get it home to make an appointment. I am writing this because of the dozens of cases of the same issues (some of which vehicles died while at driving speeds) with similar year and model GM vehicles on forums. This is a very dangerous issue which does not have a solution by GM and needs to be documented.

Truck began to idle rough and would jerk during taking off and stopping. Check engine light began flashing and stabilitrak light came on. Took it to a mechanic who reported fuel buildup. I was told that the pistons were broken as well. My truck has 88,000 miles on it and GM refuses to fix it even though there are service bulletins pertaining to the engine misfire from fuel buildup because the truck is greater than 5 years old.

While driving home, a stabilitrak warning appeared on the dash and my ac/radio began to stop but ramped back up after the dismissal. Once I got to my street, I made a left and the truck completed turned off. My steering wheel locked up, the wheel locked up, and there was no power to the vehicle. After about 3 minutes, the vehicle lights turned on and I was able to get to my driveway. I cannot imagine what would have happened if I was on the freeway.
