While just starting to accelerate, the radio shut off, the automatic locks started to go up and down, then the engine light came on and the engine stopped running. I put the truck in park, shut of the engine and restarted without issue 5 minutes later. Two days later, the same thing happened, only this time, when we went to restart the truck, it seemed as though the battery was dead as no dome lights would come on and the fob would not work the door locks. 3 hours later when the tow truck operator showed up, the truck started right up. This has happened 5 times since April 6th. The last time, the engine shut off as I was crossing a four lane highway. Luckily, we were not hit. Seeing multiple reports of the same issue make me think it is not unique to my vehicle. "dead battery" that isn't dead... "locks going up and down", "sudden deceleration". does someone have to have an accident and be killed for anyone to take action on this issue"? why not be proactive and start investigation before someone gets killed?"

Suburban 4WD 8-cyl

  • Automatic transmission
  • 66,000 miles


Having issues with various warning lights will come on in the dash (seat belt, traction control, air bags), the radio will go dead and the headlights will flicker, and it loses power and steering for a few seconds. It seems to happen when I'm applying brakes or turning corners and just at random times. I'm very worried about this happening for extended periods of time, especially on hard curves when you lose power. The dealer is reporting that it is a ground cable issue and want us to cover the entire cost of repairs. Updated 09/15/15

Low miles owner, garage kept, after several days of non-use, ie-parked in garage, vehicle will not start due to a dead battery. Baytown (craft) dealer could find nothing wrong. Current mileage 24K, still does same thing, if vehicle is not driven almost daily, the battery will go dead for zero reason and no one a Chevy know why or what. Have had vehicle at dealer several times and nothing ever fixed.

On two recent occasions my Suburban has failed to start (battery dead). I went to an auto parts store, they tested the battery and said it was good. Why is my battery going dead? both instances are the vehicle is set on accessories and the radio was working. In both instances the battery would not turn over the engine.
