A D V E R T I S E M E N T S

Traveling at 70 mph on cruise control, tapped breaks to turn off, multiple warning lights flashed, vehicle lost power, and breaks with multiple messages including -??Break system failure, top speed 62 mph-??. I lost all breaking control on the highway and nearly crashed into other vehicles due to inability to stop. Was able to pull over, turn off vehicle, and turn back on, when the breaks were working again but the vehicles acceleration was very slow. Currently at authorized repair shop. When dropped off, there were 8-9 active codes.
