NHTSA Complaint #10304172 — 2002 CHEVROLET IMPALA

I HAVE A 2002 CHEVY IMPALA. ABOUT A YEAR AGO THE TURN SIGNALS INTERMITTENTLY STOPPED WORKING. I WAS TOLD THE MULTIFUNCTIONAL WAND WOULD COST $500.00 (NOT INCLUD.LABOR) AND THERE IS NO AFTER MARKET PART. MY MECHANIC COULD NOT CONFIRM THE PROBLEM THOUGH. ALL ELSE ON THE WAND WORKS. I FEEL THIS PROBLEM IS CONNECTED WITH MY AIR/HEAT RUNNING AND/OR LOSS OF POWER. THIS IS VERY DANGEROUS AND ALMOST CAUSED SEVERAL NEAR REAR-END INCIDENCES. I AM AFRAID TO HAVE MY DAUGHTER IN THE BACK SEAT. IS THERE A RECALL FOR THIS ITEM? *TR
