    I'm going to have to double check but I could swear my 2012 Silverado has a light. ...it also has a censor that knows when the hood is open and will shut the truck off if you open it while running on remote start. (found that out. lol)

    Haha, now I know why we no longer hear of engines dying when UFOs are around.

After a few more tows back to the dealer and always dieing in the same spot one of the techs rode with her to see if she was doing something wrong. Sure enough the engine stalled in the same spot. The tech looked around and found nothing wrong under the hood but then noticed the hood ground strap was not connected from the factory so while waiting for the tow he took care of it. The truck arrives and they go to load it on the rollback but it starts up. Baffled they do more test drives with no more problems.

    Random things like ground straps and weights bolted to exhausts are there for a reason, be it obvious or not

    A friend a long time ago had a VW that did the same thing...they finally figured out it was interference from the local Doplar Radar deal...he would pass it and the car would die in the same spot every day.

    The switch for the hood to detect the latch position is in the locking mechanism. It prevents the remote start from working should the hood be open. My 2012 (LT) has no light.

    So as noted upthread the bonding strap is there mainly to provide better RF shielding.

    It works both ways. It reduces the amount of AM radio interference from the ignition, fuel injection, and ABS system, and it reduces the effect of strong RF fields on the engine controls.
