I purchased my 2019 Sierra LT 4x4 in Decmber 2019. The infotainment system started going blank 2 weeks after driving the vehicle. Since December, I have taking it in to the dealership for the problem to be resolved at least 15 times where the problem has not been resolved. The dealership even requested an engineer to help solve the issue, which the engineer AND the technicians expressed no resolution to the problem. Based on the federal lemon law, the dealership should have either bought my truck back or put me in a comparable truck because my truck only has only 6700 miles on it. However, GM and the dealership are unwilling to agree to either terms of the federal regulatory laws. I am shocked and appalled by subpar customer service of GM. Ther service manager has done everything he could do, which I appreciate. The true problems are related to authorities above him. Can someone please assist me with remediation of the problem?
