ON CERTAIN SPORT UTILITY VEHICLES, VIBRATION AND HEAT MAY CAUSE THE TAIL LAMP/STOP LAMP BULB TO LOOSEN IN ITS SOCKET. IF THIS OCCURS, THE BULB MAY FLICKER AND EVENTUALLY BECOME INOPERATIVE.
AN INOPERATIVE BRAKE LAMP WILL NOT CONVEY THE DRIVER'S INTENTION OF STOPPING TO DRIVERS IN FOLLOWING VEHICLES, AND AN INOPERATIVE REAR TURN SIGNAL LAMP WILL NOT CONVEY THE DRIVER'S INTENTION TO TURN TO DRIVERS IN FOLLOWING VEHICLES. BOTH OF THESE FAILURES CAN INCREASE THE RISK OF A CRASH.

SPEEDOMETER BEGAN ACTING UP A FEW MONTHS AGO AND NOW IT'S CONSTANTLY ACTING UP. SOMETIMES IT SHOWS ME GOING FASTER THAN ACTUAL AND SOMETIMES IT SHOWS ME GOING SLOWER THAN ACTUAL AND SOMETIMES IT JUST SITS BELOW ZERO AND DOESN'T MOVE AT ALL. NOW THE OIL PRESSURE GAUGE STOPPED WORKING. IT READS ALL THE WAY PAST 80 AND DOESN'T EVEN MOVE WHEN I TURN THE VEHICLE OFF. I DO NOT TRUST ANY OF MY GAUGES NOW. I CANNOT BE ASSURED THAT ANY OF THEM ARE READING CORRECTLY. *NM
SPEEDOMETER DOESN'T WORK. IT WILL JUMP AROUND AND STICK ON ANY GIVEN SPEED AND REMAIN THERE. SOMETIMES WHEN THE VEHICLE IS RESTARTED IT WILL DECREASE 5 MPH FROM THE POINT AT WHICH IT WAS LAST POSITIONED. I CANNOT REGULATE MY SPEED WITHOUT THE SPEEDOMETER AND AFRAID THAT I WILL CAUSE AN ACCIDENT. IT HAS NOT BEEN FIXED.
