2005 SAAB 9-3 Exterior Lighting Problems

FREQUENTLY THE CAR STALLS SUDDENLY IN TRAFFIC, LOOSES POWER I CAN'T ACCELERATE THIS IS VERY DANGEROUS POTENTIAL TO GET HIT. THE OTHER PROBLEM IS THE CAR VIBRATES AND ALL OF SUDDEN A LOT OF SMOKE COMES OUT FROM BACK AND RICH GASOLINE SMELL COMES AND THE SPEED TURNS TO 0. I TURN IT OFF FOR FIVE MINUTES AND RESTART SOMETIMES IT STARTS OK SOMETIMES IT VIBRATES AGAIN. THIS HAPPENS VERY FREQUENTLY

ONGOING DURING ROUTINE DRIVING: THE HEADLIGHTS ON MY 2005 SAAB 9-3 BURN OUT ON APPROXIMATELY A MONTHLY BASIS REQUIRING REPLACEMENT OF THE BULB. ACCORDING TO KNOWLEDGEABLE SOURCES THIS IS DUE TO A CORROSION ISSUE WITH THE HEADLIGHT SOCKETS KNOWN TO THE MANUFACTURER AND SERVICE PROVIDERS. THIS IS A SAFETY CONCERN DUE TO THE FACT THAT WHEN ONE HEADLIGHT BULB BURNS OUT - THE OTHER HEADLIGHT BULB BURNS OUT SHORTLY THEREAFTER EXPOSING ME TO FOUR OCCURRENCES WHERE I HAVE LOST ILLUMINATION IN BOTH HEADLIGHTS WHILE DRIVING AT NIGHT. IN ADDITION, THE HEADLIGHT SOCKETS ARE OF POOR CONSTRUCTION AS I HAVE HAD TWO OCCURRENCES OF ONE OF THE THREE TABS WHICH SECURE THE HEADLIGHT SOCKET INTO THE HEADLIGHT ASSEMBLY BREAK OFF. THIS INITIALLY CREATES A SITUATION WHERE THE HEADLIGHT BULB MOVES OUT OF ALIGNMENT CAUSING IMPROPER ILLUMINATION OF THE ROADWAY AHEAD. ULTIMATELY, THE BROKEN TAB ON THE SOCKET LEADS TO BULB FAILURE...
