2020 GMC SIERRA 1500 Complaints

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.

BACK UP CAMERA IS AWFUL AT NIGHT. THIS IS A SAFETY ISSUE BECAUSE YOU CANNOT SEE ANYTHING WHEN BACKING UP. MY TRUCK HAS 323 MILES ON IT AND I WENT TO DEALERSHIP THEY SAID I WOULD HAVE TO LIVE WITH IT. THAT IS NOT ACCEPTABLE TO HAVE A SAFETY FEATURE THAT IS FAULTY.

VEHICLE EQUIPPED WITH L87 6.2L. AT 197 MILES ENGINE SUDDENLY CEASED OPERATING AND WOULD NOT RESTART. THIS OCCURRED WHILE STOPPED ON PRIVATE ROAD. VEHICLE HAD TO BE TOWED TO DEALERSHIP WHERE THEY FOUND P0300 AND DIAGNOSED BROKEN #4 CYLINDER EXHAUST VALVE SPRING.

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.

DISPLAY IS DANGEROUSLY TOO BRIGHT WHEN BACKING UP CANNOT SEE TO BACK UP VEHICLE SAFELY

THE NIGHT TIME BACKUP CAMERA IS REALLY BRIGHT AND BLURRY AND IT MAKES IT HARD TO SEE WHEN BACKING AT NIGHT
