While driving vehicle, started to rough idle and almost caused a vehicle accident because I was unable to stop the car while driving, engine shutdown while driving and lost all power and braking & steering ability, restated vehicle and got burning gas smell from vehicle exhaust pipe and check engine light on with code p0014, got vehicle serviced and had new sensor installed but now getting pinging sound from engine under load and while driving at speed and minor vibration while at idle. I feel this is a serious issue with this vehicle where almost feel unsafe driving vehicle due to running risk of engine shutdown while at speed and unable to steer or brake when engine stalls due to this condition with code p0014 in cars computer. Would really like to be contacted about this issue, gm should have a recall to inspect these systems and provide free repairs of any faulty sensors and provide a full service check on this vehicles. I felt real unsafe to drive this vehicle due to worrying about causing engine damage or having a accident because of this high end failure of this componet.
