My buddy has a 90 Cadillac Seville that we have put a lot of time into. She sounds better than my F-150. Anywho...

For about 6 months the digital instrument cluster didn't work, and niether did the information center display down in front of the shifter.

It worked at one time, but the car was posessed when it did work. Like the lights would turn on by themselves, turn signals would flash for no reason. So my buddy took a ballbat and smacked the top of the dash and EVERYTHING went dead.

So for about 6 months or more, he drove not knowing how much gas he had, how warm the car was, how fast he was going, nothing. He got pulled over a time or two and they never said anything about it.
