NHTSA Complaint #11431903 — 2019 CHEVROLET TAHOE

While driving on the freeway truck had lost all power and steering and braking capacity. The screen on dash went completely black with no warning signs. Vehicle could not accelerate and or brake other than drift in lane. Vehicle was without power for a brief time until power came back was able to not crash vehicle as this happened at a high rate on speed on busy freeway. When power did engage back on the dash lights now were full brightness and no control to dim it down could have been sign of definitely Electrical issues. This had occurred several times since it had this major problem! I then urgently took my vehicle to specific Chevy dealership for service and was refused service at dealership for the major electronic black out. I had no other choice but I then had contact Chevy customer service line to bring them this major problem four months ago. To this current day I still haven’t had any support or assistance in addressing this major problem with my vehicle! Chevy support or lack there of has only delayed addressing my to get serviced to see what’s causing this problems!
