The display for the backup camera and infotainment system became blank. Other owners have the same complaint. This is a serious safety issue because I was backing up when it went blank.

Told that the vehicle history shows records of past "loss of communication to dic" but as they can't immediately reproduce no action was taken.

On December 14, 2020 my Sierra with 2339 miles displayed, at startup, the power steering was out, to drive with care. Also displayed service ESC and traction control failures. I drove with much difficulty, without power steering, ten miles to the nearest GMC dealership, lafontaine in highland, mi. I picked up the vehicle on December 29, 2020 with an additional 60 miles. The service personnel said they were unable to duplicate the problem, therefore no repairs were made. Lafontaine had contacted General Motors tech center who offered no solutions other than checking the battery and wiring harness connections. The problem has not reappeared in the fifteen days since I picked up my vehicle.

On two separate occasions, the truck has been dead when attempting to crank. There were no lights or devices left on after the previous time the truck had been used. Something is drawing power from the battery causing it to be dead. After recharging the battery, the check engine codes read that there is a problem with 'brake light illumination.' Help in determining wha T is causing the battery to die on such a new vehicle would greatly appreciated! I'm uncertain at this time as to whether or not the brake light illumination is causing a safety hazard.

After having all sorts of warnings over time like "service ESC, " "service parking brake, " and more, I now see "brake system failure: 62 mph top speed" flash across my dash. I am reading and hearing that this is a very dangerous problem. New truck. Brand new. Had it less than a year. Brake message always on start up.

There is no way to permanently disable the auto start stop on the vehicle. Several others have complained about this, no response from GM. There needs to be a firmware upgrade to the ECM to allow the owner make the decision on if that is enabled or disabled. On mine, I have to push a button each time I start the engine to disable that. Some GM vehicles don't have that option.

Keep getting "service safety restraint system " alerts. Vehicle only has 550 miles. Alerts are intermitent when driving. Contacted the dealer and was advised that unless it remains on they could not trace the issue.

Everything was fine for about 6 months after having purchased vehicle as new. Then I got warning lights asking me to both service the parking break and service ESC with a warning that driving would be compromised just over 60mph. I notified dealer who says they fixed the glitch but it happened again. The last time, most recently, I tried to start the truck the next day and all the warning lights came on. This was followed by a complete shut down. No engine, no lights - not even lock/unlock with key fob. It had to be towed. This is a 2020 vehicle and seems like it will strand me some place at the very least. Awful, expensive, and perhaps deadly dynamics here. GMC, get your act together. You owe us immediately. Provide the fix immediately or give me money back with no contest.

At 550 miles had to tow to dealer. They said needed to reprogram transmission. Now at 4000 miles, went to start and vehicle will not do anything. No power. It is being towed to dealer again. Pretty much bought a lemon as it looks now.

Battery was dead in the garage. Called road side assistance who jump-started car. Car would not go into gear. We rolled it out into driveway where it sat for 24 hours. When it was loaded for travel to dealership, it cranked and was driven up on wrecker trailer like it had no apparent problems. Was carried to dealership where they recharged and checked the battery and reset 14 different codes which were lost with the low voltage.

Review camera is extremely bright when backing. It's so bright that a glare is thrown onto rear window making it next to impossible to see out rear window or use side view mirrors. I often revert to to open drivers door and looking backwards that way. Someone is going to get run over as you cannot see where you are backing. Very dangerous!
