I first started having issues on 7/28/18 at night. I was driving and all of a sudden my whole instrument panel lights up as bright as possible. It showed every warning light possible. It said my trucks temp was as at zero, speedometer at zero while driving, battery was at zero, rpm's also at zero. I got to a safe pull off spot and tried to find the issue. After a couple minutes, it went away, but while driving home...it came back on. I took it home and didn't drive it anymore for the night.

The next day I did some research on possible issues. I check all possible fuses with no issues. Truck turned on fine, no warning lights. After some frustration and back pain from trying to get to the fuse panel I took a break and did some more research then came back to it. This time, no power, no ignition, no ticking from trying to start. Power lift gate would not work, power locks would not work with remote. I tried to lift the gate with the handle...nothing. After going through fuses I checked earlier to make sure none had blown, no problem with the fuses. Again, I walked away so I wouldn't get even more frustrated. I made a quick stop to the truck to see if it progressed any. It started up right away and I let it run for a bit after which it did it again but went back to normal quickly. My radio is not working and hasn't been since 7/12/18. It shut off all of a sudden while driving home from PA. The whole radio power went out, then popped back on. To this day, I have no radio volume but am able to change stations. Cannot hear phone calls from Bluetooth or OnStar. Music going through the auxiliary cable also have no sound through the speakers.

I own a 2011 GMC Acadia. Started in the last 6 weeks getting dash lights about stabili-trac problems and or brake issues or check engine. Car would stall and give warning lights, also shut down engine power to about 20 %. Would hardly pull itself into the driveway. After shutting down the engine, things would appear normal. Took the vehicle to a GMC dealership and was told nothing was wrong but normally they change the throttle body when a complaint like this comes in. I did not have the $300 repair made and had no trouble for about a month.

Now, in the last 5 days it has happened 3 times. I plan to have the throttle body replaced since this is the only repair that I know of. I had the same problem with my 2003 GMC 4x4 about 5 years ago and it fixed the problem. My thoughts are--GM has a problem they won't own up too. They will have a recall for Safety Issues after enough people have been in accidents. I plan to keep all my repair costs and turn them in after the recall that will happen some day.
