Seat belt on drivers side does not sound any type of warning that seat belt is not on until i am sometimes 5 miles or 2 miles or just 3 blocks away before any sound comes on to let me know i do not have seat belt on. its a extremely light sound whereas the passenger side starts making loud beeping sound if no seat belt is put on before i even get out of the driveway. the drivers side does show at some point on instrument panel the small red seat belt warning. my other cars immediately make noise before you can even back out of the driveway if no seat belt is detected unfastened. the gas tank gage never sends any warning signals that the gas if past the empty mark as i discovered when on a 3 mile bridge and discovered that my gas tank was completely on empty when i looked at instrument panel. it gave me no warning at all of this problem. i was lucky to be within a mile of a gas station as i was going off the bridge to add gas. i took car to cadillac dealer where it was purchased and they found no problems but i have had many issues when car was purchased that they did not want to fix such as tire problems going flat over and over. they finally replaced one of the wheels.
