Check engine light came on for code P0014. Car intermittently will not start. Not repaired yet, but suspecting camshaft sensor from what I've been told.
06 g6 gt shutting off while driving. Says engine disabled then after about 1 min starts up fine. Happens randomly. When it first happened it didnt do it again for about a year. Now it happens a couple times a week. Making an appt with dealership. Hope its not too expensive :(
Check engine light - P0011 after scanning. Engine idles rough intermittently and at stops.
I am so sick of this car. I have had it a year and nothing but problems. GM know of the problems and makes the consumer pay for alll repairs. Shame on you GM!!
after starting and driving about 15 minutes, all guages on dash panel go to zero and check engine light comes on. Removing battery terminals resets gauges and check engine light be recurs after about 15 minutes of driving time.
