I had the exact same issue than another user who reported the following:

''Upon starting the car we have no working gauges. The temperature and gas level don't work. And the following error messages show up on the dash. Service air bag, tire monitoring system, front camera, parking assist, side detection system, and theft deterrent system. The car it basically undriveable. The blinkers do not work, heated seats (though that is minor) radio stops working. We don't know what the temperature of the engine is, how much fuel we have and how fast we are going. There is only 68,800 miles on it. When I call the dealership (they're the only ones with the technology to look at this and troubleshoot) they tell me it's a few hundred dollars just to run diagnostics. This is ridiculous that the car is this unsafe to drive but I have to pay to diagnose it. Then I find out just to replace the side detection system will cost me like $700. I can't imagine what it would take to fix this bigger issue. I'm forced to pay to have diagnostics run at this point because I can't have my wife and daughter driving around in this vehicle when it's this unsafe. ''

I went to GM and they took out the 2 blind spot boxes underneath the car, they said they were broken, pretty much fixed the problem entirely (except that now I don't have these blind spot lights anymore). GM told me i had to spend 1500$ to replace them and that my car wouldn't work without them (because it was supposedly the main port for my car cpu) but it works just fine. I only paid 50$ for the diagnosis and the removal of the 2 defective pieces (they told me it was normal defect after 5 years...) Seriously guys, make cars more strong than this.

all engine light alerts while driving the gauges bounce to

The car started acting up while driving it. The whole dashboard lit up and the side mirrors with the side alert were blinking. My gauges for the my speed, battery, water level and gas were bouncing up and down. The heater would turn off and on the entire drive. The radio and information screen was warning me of all kinds of issues. My poor wife totally freaked out and called me in a panic. The mechanic said all of the codes were listed on the computer report when they check the system. Now I have to go to the dealer. I hope they can figure it out. The warranty better cover this.
