Asked by May 03, 2017 at 07:14 PM about the 2007 Chevrolet Tahoe LT 2WD

Question type: Maintenance & Repair

After turning car off battery dies in
sometimes less than an hour.
Several trips tip dealership with no
resolution. They said it needed a
gold battery bought that no fix
next trip it needed a battery
current sensor replaced that still
same problem. Sitting in the car
with it off no key in ignition there
is a clicking noise sounds like
door lock not sure but the
speedometer is jumping from
behind the zero to the zero mark!?!   
Help please! I've looked on some
other forums people with similar
problems said they had bcm
reprogrammed and it fixed
problem. Just need some advice
before i waste any more money

BCM's are very voltage sensitive, if there was a power loss the programming can be messed up, it just seems odd that the dealer didn't catch this the first time it was in as it is a know problem.
