Driving along and the door locks click off then the dash goes through showing all its symbols , then the engine symbol show , check Powertrain ? what does this mean ?

The yellow car and lock symbol that appears on the dashboard of your Pontiac G6 indicates that the vehicle's security system has detected a problem. This symbol may appear if there is a malfunction with the system or if the system has been triggered by an event such as a collision or attempted break-in.
If the security system is functioning properly and the yellow car and lock symbol is still displayed, it is possible that there is a problem with the security system sensor or wiring. It is recommended to take the vehicle to a mechanic or a Pontiac dealership for further diagnosis and repair.
In the meantime, you can try pressing the unlock button on the remote or using the key to unlock the doors and see if the symbol disappears. If the symbol remains displayed, it is possible that the security system will need to be reset by a professional.

If it's an exclamation point inside a triangle, it's called a master warning symbol. This is the Master Warning Light symbol. If this light is on, there will likely be text displayed as well on the instrument panel, or another warning light. Look for text in particular. It could very well point out something as serious as low oil pressure. If the engine is not running, you can't very well check your gauges, but you may have lost all oil pressure or overheated the engine. Recommend you consult a mechanic familiar with your model.

Power steering has nothing to do with doors.Check door switchs!
They might be bad!Hope this helps

lost the operators guide, its in the book in the glove box.
all dash symbols stated in English or (others)
goggle will find it fast. or any dealer (oops chapter 11)

Check the fluids, oil, antifreeze maybe a low sensor? Unhook the battery to reboot the computer. Just a diagnostic start of elimination.

door is partially open or switch on a door is out of position.
takes 2 people but goes fast. open each door and manually
push the switch open to break contact and stop the circuit from
working.

you can look in your glove box and find the manual book.
you will be able to find the symbol and what it means. It could be serious or just a minor oxygen sensor. Can you show what the symbol looks like?

I don't have any pictures but if it's flashing it's probably the check engine light (some vehicles show this as a symbol instead of the words). If it is and it's flashing, that indicates the engine is missfiring and could potentially damage the catalytic converters. A diagram of all the warning lights is shown in the owners manual with a nice description

the lock is anti theft, This sounds like an electrical mess, Possibly poor connection at a wire harness

The negative number means the car should have had it's oil changed that many miles ago. Oil life starts at 100% for new oil & counts down every 10%. At 15% the display will always show, which means it's near time to change the oil.

usersteve83, your oil may have been changed but the timer not reset. Reset the timer as shown...
1. Turn ignition to the "ON" position. (do not start engine)
2. Press SEL/RESET repeatedly until the oil life indicator is displayed.
3. Press & hold the SEL/RESET for about 10 seconds until it blinks then let go of the button.
4. Press the SEL/RESET again for about 5 seconds or until the oil life indicator resets to 100%.
