2020 Gmc TERRAIN problems and owner complaints

EVERY WEEK IT'S SOMETHING DIFFERENT. IN MOTION... NO CRUZE CONTROL. NO AUDIO. DON'T DRIVE OVER 50MPH BRAKE PROBLEM. PARKING BRAKE ENGAGES RANDOMLY AND WITHOUT USER ENGAGEMENT. NO AWD. NO STABILITY TRACTION. THIS HAPPENS SO FREQUENTLY THE DASH INDICATORS HAVE BEEN REDUCED TO 'IDIOT LIGHTS'. AT WHAT POINT DO I BECOME CONCERNED? THINGS APPEAR TO RESOLVE WHEN THE ENGINE IS TURNED OFF AND BACK ON, SOMETIMES....I COMPARE IT TO OTHER GLITCHY TECHNOLOGY. HOWEVER I POTENTIALLY COULD BE AT AN 80MPH CRAZING SPEED WHEN I DECIDE TO IGNORE THE IDIOT LIGHTS..…

After starting my vehicle on May 28, 2021, the infotainment screen was pink and green with lines. The radio was playing loudly, and I had not previously set it to that volume. Additionally, the volume control button did not work. I headed to the nearest GM dealer, and I did not attempt to turn off the screen. A service representative said I needed an appointment, and I could not be seen until one day during the next week. I needed the turn-by-turn navigation, and I did not know if the issue would worsen or cause other issues, so I asked for …

This 2020 GMC Terrain has a "feature" called autostop. This is not a switch to turn this off. It would not be so bad if the engine would run for 5 minutes at a stoplight before stopping the engine but it immediately shuts down the engine after a stop. This is getting annoying and dangerous due to the delay in getting the car moving. I have only had the car for a month. I understand that later gmc cars have a disable switch. This car should be recalled and either disable the auto stop permanently or be able to disable the "feature" on demand. …

I just purchased this vehicle about 2 weeks ago, and was driving through the fog/cold weather and my check engine light came on. Went to O'Reillys and had them check the code. Came up as P0299 (My car was telling me that the engine power was decreased) I had a loss of power I could feel while driving as well. The code said turbo under boost. After I got back into town and the weather was warmer and no fog was present, the turbo started working again. I brought my vehicle into the dealer where I bought it from and they took it to their mechanic …
