I have a 2001 Impala 3800 that has started having problems
with the security light coming on and staying on. When the
light comes on the DRL start flashing and will not stop.
This happens after the car has warmed up and has been shut
off for a few minutes. The lights begin flashing and the
security light comes on and stays on. The only way to get the
lights to quit flashing and get the security light to shut off
is to turn the car off, raise the hood and let the engine cool
all the way down.
Has anyone got an idea on how to fix this problem and what
might be the underlying problem. The car has been to the shop
5 times for this problem, and appears to be fixed for 1 or 2
days, than it's back to the same thing. The ignition has been
replace twice (by the garage believing that's the problem) and
still no fix.
I contacted GM and they "researched it" but couldn't give me
a fix or underlying problem. I did get a nice letter back telling
me "thank you for your interest in GM" and "hope we can be
of further assistance in the future". Along with the same contact
information I've already been dealing with..
