The car was cruising along for 15 minutes on the journey home, without any hint of a problem. All of a sudden, every warning light in the car came on and it began slowing down. The speedometer dropped to zero, even though we were going 65 MPH. The transmission shifting felt clunky, too. The coolant, ABS, airbag, DSC dynamic stability control, brake, service engine soon, yellow gear of death, and others, came on and cycled through like a …
