Yes, It has happened to me. I put a sunshield in my windshield, left car running while getting items out of trunk, then turned off car and locked it immediately. I had taken vehicle into pontiac dealer and everything checked out okay. Then they received a bulletin, not a recall, but a bulletin. I have a copy of it. Here is what is states:
7/19/06 2004- 2006 model gtos
Pic3483c was created to remove the information tht a fix was being worked on. No updated calibration will be available. If the vehicle were to ever lose power at night while still rolling, the current would allow the headlamps to stay on. Please discard PIC3483B
With headlamp switch in auto mode, headlamps may remain on with ignition switched off and driver's door opened. headlamps will remain on, potentially discharging the vehicle battery.
The BCM does not recognize that speed has dropped below 6mph if the ignition is turned off prior to or as the vehicle comes to a stop. Due to lag in updating vehicle speed, depending on the rate at which the vehicle is stopped, the BCM may continue to register some vehicle speed momentarily after the vehicle has actually come to a stop. To activate the headlamp off condition, BCM must register a vehicle speed of zero, as well as driver's door switch cycled. If the ignition is switched off while the BCM is registering 6mph or greater, the headlamps wil remain on even following cycling of the drivers door switch.
As the vehicle condition cannot be rectified, customers experiencing this condition must be advised to ensure that vehicle is brought to a complete stop, and perhaps delay switching off the ignition momentarily after stopping the vehicle.
No other action should be attempted in order to overcome this condition.
Note for the 2004 GTO Only:
If the BCM does not recieve the door open input from the drivers door jamb switch, due to corrosion or a poor connection, the BCM will not turn off the headlamps. The BCM uses the jamb switch to see the door open as opposed to using the switch to latch. you can see the latch switch on the BCM data stream, but not the jam switch.
Remove the door jamb switch to inspect for corrosion or a poor connection at the switch. the door jam switch is held in place by a screw and is easliy removed for inspection. On the 2004 GTO, the door jamb switch is located just below the a pilliar. if corrosion is found, replace the door jamb switch and verify proper operation of headlamps..
"No" re-calibration or retuning of the vehicle computer is going to be done by GM. The dealership said GM has not plans of correcting the problem.
Having this information I asked the dealership if i should keep the lights on the off position instead of Auto. They highly recommended against that. So other words, dont come to a fast stop, shut your car off, and run off.
Hope this helps. this bulletin came from gm and was given to me at my dealership.
