ok i have a 04 grand prix gt non supercharged. and all of a sudden today it started doing some crazy shit.. while driving the display that tells you if your tire pressure is low and stuff like that. it starts dinging and starts saying that check charging system, abs, temp, and so on and it dings the whole time. then it shuts off and comes back on.. while that is going on all the gauges in the dash stop working and fall to 0.. and they wont work again until you shut the car off and turn it back on.. and went to the parts house and had them test the battery and alternator and they say that its reading just fine.. anyone have any ideas or had the same problem????

Possibly a loose electrical connection at the main CPU plug? Has any work been done recently on the car?

Check battery voltage, alternator, grounds etc these are sensitive cars when it comes to electrical. My car did the same thing turned out to be a correded hid ballast i put oem light bulbs back in an it went away. Hope that helps.
