Leased vehicle has stopped for no reason 3 times in traffic. No indication of problems, no dashboard lights lit before vehicle stopped. The vehicle just stopped dead cold with no warning. Consumer has been in contact with dealer 3 times and taken the car in for service, the dealer could not fix the vehicle, and the vehicle has a vehicle data recorder on board. That still has not helped and problem still has not been fixed. Made a complaint to the BBB. GM customer service and they denied the consumer's complaint. The consumer has every printout from the dealer that states the problems. The car has a pattern of problems.
