Dealer wants us to take it back and wife is scared to drive it due to no fixes or repairs. …”

“While driving in approximately 10°F weather after the vehicle had been parked outside overnight during snowfall in Chicago, the vehicle displayed a warning that said “Do Not Drive — Maximum Speed 43 MPH.” At the same time, the brake pedal became extremely hard and the vehicle had significantly reduced braking ability, requiring much longer stopping distance.
