Warnings problems of the 2019 Chevrolet Silverado 1500

*lifter / rocker failure *there was a good jerk of the truck (safety) *confirmed independently inspected by dealer, police, ect *small stuttering right before failure.

Truck was purchased brand new. Since I first got it I've had problems with the backup camera flashing, going completely blank, and giving an error to service rear camera system. Always occurs while in reverse. Dealership has tried fixing issue several times and now states this safety issue is normal in their vehicles. 11/25/19 dealership replaced back up camera due to lines flashing through screen while backing up. Screen frequently went blank and would also give �service rear vision system� error. 01/09/20 backup camera system continues to flash, go blank, and give error message. Dealership stated camera was tested and functioning as intended. 10/22/20 same issues persist with backup camera system. Dealership verified problem and replaced camera assembly on 12/14/20. 01/27/21 same problems persist. Dealership updated system and claimed not to be able to reproduce problem. While picking up vehicle flashing occurred before I even left the lot. Dealership requested I remove amp (installed long after problems started occurring; have documentation) before further diagnostics could be performed. 02/26/21 dealership said they checked other trucks in their lot which have the same issue. Says a voltage drop in the electrical system is what's causing the issue and stated there is no fix because this is a normal operation. 03/05/21 problems persist. Dealership built a new electrical harness and replaced radio system. Problem still continues. 03/09/21 talked to gm customer care. They state the safety issue with the backup camera flashing and going blank is �operating as designed. � 03/11/21 customer care stated vehicle is performing properly and as expected even though back up camera system still having problems. Says there's nothing else they will do for me to fix the issue at this time.
