Please report these issues to the NHTSA 1-800-327-4236
My 2003 Silverado 1500 Z71 5.3L 4WD, Ext cab frequently shuts down !!! The warning signal beeps 4 times (without any visual indication of what the problem is), the door locks cycle on and off and the engine quits !!! First time it happened I was on an Interstate at 75mph and after restarting (by shifting to neutral and turning key) also had to stop to change pants !! (driving a non responsive 2 1/2 ton brick at high speed is not cool !!)
Took it to a dealer and they ran diagnostics to no avail. I never know when or why it shuts down... Does not seem to matter at what ever speed. I feel it must certainly be an electrical problem somewhere but do not know where to start !!! It could be coming from the driver's door electrical connections ???? as quite often, my seat heater comes on at max temp (3 lights). Never know when that is going to occur also. I posted this previously but no responses !! still need help....

[QUOTE=moyneur;437759]I purchased a Certified Pre-Owned 2014 Siverado 4x4 last June (2019) with 19000 mile on it. I have had the vehicle completely shut off, like some one pulled the plug on it, three times, twice in one day and one more time two days later. It's at the dealership now, the system did show some issues with it shorting out but unable to find out whats wrong. They did check ground "PIT5405" and was good. They are trying to duplicate the issue so the can fix it, not realy sure what that will tell them. I'm just afraid that I purchease some ones problems and now I'm screwed.
I am having same problem , but it shuts off more as I am turning . This morning it died making a right turn with my horse trailer on the back , I lost power steering And brakes. Luckily I did not hit the car I was turning towards .
2 years of this with no solution . Anyone have suggestions ? If there aren’t any codes coming up , could it be narrowed down to wiring somewhere ?
