2007 tahoe dies unexpectedly

[Javsamjor]

Alternator,starter, battery all new. Truck radio goes out, electronics goes out, lights do out, the truck does while driving literally. Now truck back in dealership bc it was completely dead after it was parked for several hours. It took awhile to jump start it. But in while waitingwith NO key in ignition, cabin lights flickering, doors clicking, gauges bouncing up/down. Dealership just called and told me nothing wrong with truck. Seriously! am unable to post the video of it but can message to anyone with ideas.. Need suggestions please... LUV my truck but it's becoming a safety hazard. Thx everyone.

Bad ground somewhere. Need to check all grounds under hood and along frame. And at firewall.

Any suggestions of where to look first? Going to pick up truck from delearship Monday. Have a friend who is willing to take a look, but we r not mechanic buffs. Thx so much for ur help. Happy Valentine's Day.

After finally calling GM directly and getting them
Involved-my negative ground cable for the battery was bad. Apparently when these vehicles have low voltage, the electronics have a tendency to go hay wire and the vehicle will not start. The vehicle can also die while the gears r in drive. Will see if this fixes the radio spontaneously turning off too while driving. Maybe getting a second battery and alternator will be a good idea. Wanted to let u all know in case someone else has this issue.

this is common with all vehicles with computer controls....computers require X voltage to operate...

Hope it fixes it. Good clean tight connections at the battery positive and ground and all other grounds under the hood and at frame and firewall are important.

Thank u guys for ur advise. a friend of mine has a 2009 tahoe and it's doing the same thing, she had changed her negative battery cable and its still doing it. Hopefully this solves the issue but I'm guarded. Again thx

Negative battery cables are a very common issue only have not yet experienced one where it actually causes vehicle to stall only once vehicle was shut off and a no crank no start symptom would occur.. another common issue is a body control module that will cause the vehicle to stall. The BCMis the power mode module that distributes power to most electral components and if those components provide class 2 serial data to modules that rely onthat data to operate properly everything will go hay wire and eventually shut the vehicle down
