The airbag light keeps coming on and dinging every few minutes.

Check the ground cable at the battery. They could have left it loose.

It is saying your trunk lid/trunk sensor is open, unlatched or the sensor is not functioning properly. Check the wiring going to your trunk lid sensor, make sure it is clean and not corroded. Sometimes a good cleaning will do the job.

When you turn the key on the airbag light should come on for the bulb test. If the bulb doesn't work, it will beep to let you know the bulb is out. The only way to stop it from beeping is to replace the bulb.

it sounds like the oil pressure sending unit. it located a few inches from the oil filter. only takes a few minutes. the part is cheap, like 10 0r 20 dollars. maybe less.

1. Turn off the overhead over-ride switch. Drive again. Do the chimes stop? If yes, the door is not closing properly due to the door contacts. Clean them yourself or have them serviced.
2. If the chimes did not stop in step 1. above, it's not likely the door but rather something else.
3. Chimes occur for many reasons. Suggest checking - a. are the rear back-up warning sensors blocked/dirty? b. any other lights on the dash like oil, abs, airbag, etc? c. passenger side airbag disabled - something heavy placed in passenger seat?

In my experience, it's the automatic door contacts. We have a long history of problems with these auto doors, that are still not resolved. problems all throughout the warranty period, and now into the extended warranty period. We must unite and get GM to resolve the quality of these doors. My next step (next incident) is going to be to have the dealership inspect the entire wiring system.

TAKE VECHICLE TO GARAGE OR DEALERSHIP.YOU HAVE A LOOSE WIRE OR SHORT.NOT SAFE TO DO YOUR SELF.AIRBAG COULD EMPLOY WHILE YOU WORKING ON IT.

to keep yourself from getting a broken nose. you need to take the car to a service center. theres a problem with your airbag

is your vehicle equipped with a passenger side airbag off switch you turn w/ the key?turn it on

the Body Control Module is bad. If your security light goes off later then most likely.
