New engine placed in vehicle because loss of power. Since then vehicle looses all power in the midst of driving. Alarm also goes off without notice. New battery, then new alternator, and now new engine battery cables. Was told no power to engine then too much power. About $1,500. 00 out of pocket to get fixed. Truck continues to shut off and loose all power when driving in the city.
Vehicle, which I had just bought used from a dealership, died while in motion repeatedly on both a highway and on a street after being driven for a period of time. Did not occur during test drives or during inspection. Instrument panel lights, gauges and door locks operated erratically before vehicle suddenly stopped. Would not promptly restart. Took several attempts before it started. Chevrolet dealership had vehicle for over a day and could not duplicate the electrical problem. My search on google and youtube indicates that there is a common problem with corrosion of the battery cables, - just "google" 2007 silverado electrical problems and you will see what I mean. Why the chevy dealership could not or would not diagnose this I don't know. I replaced all the necessary battery cables and the problem has not reoccurred. In my opinion, this is a known and common fault that chevy should be well aware of and the fix readily available.
