“WE HAVE TO KEPT CHANGING THE BRAKE LIGHTS IN THE BACK BECAUSE THEY KEEP GOING OUT EVER FEW WEEKS. WE EVEN WENT AND BOUGHT A NEW STOP SIGNAL SWITCH BUT THAT WASN'T IT. WE WANT TO KNOW IF THERE WAS A RECALL ON THE BRAKE LIGHT AND THE WIRING AND WHY THEY KEEP GOING OUT. WE HAVE HAD ISSUES SINCE WE BOUGHT IN JUNE 2014. WE ARE JUST TIRED OF KEEP POURING MONEY INTO IT BUT I DON'T WANT AN ACCIDENT OR TO GET PULL OVER EITHER. THE ONLY LIGHT THAT NEVER HAS AN ISSUE IS THE BRAKE BAR ON TOP. *TR”
“BRAKES LIGHTS AND HEAD LIGHTS ON MY 2003 PONTIAC MONTANA HAVE BEEN GOING OUT PERIODICALLY FOR SEVERAL YEARS NOW. AFTER REPLACING LIGHT HOUSING, BULBS AND OTHER COMPONENTS, THE BRAKE LIGHTS CONTINUE TO BLOW OUT. AT ONE POINT WE THOUGHT IT WAS BECAUSE OF ALL OF THE MOISTURE BUILD UP, SO AFTER MY HUSBAND REPLACED THE HOUSING AGAIN, HE DRILLS HOLES IN THE BOTTOM OF THE HEADLIGHT COVERS TO HELP DRAIN MOISTURE. THAT HAS SEEMED TO HELP IN ONE OF THE LIGHTS. THE BRAKE LIGHTS ON THE LEFT SIDE CONTINUE TO GO OUT ABOUT A DAY AFTER EVERY REPLACEMENT. MOST OF THE INTERIOR LIGHTING HAS GONE OUT AS WELL AND THE SUSPENSION IS TERRIBLE. *TR”
“WE HAVE OWNED THE CAR SINCE OCT 2005, PURCHASED USED FROM A SATURN DEALERSHIP. CAR WAS INVOLVED IN A GAS TANK RECALL, HOWEVER WE WERE NOTIFIED NEARLY TWO YEARS AFTER WE HAD A RUPTURE THAT DROPPED AN ENTIRE TANK OF FUEL ON THE DRIVEWAY AND WERE TOLD WE WERE LUCKY TO BE ALIVE HAVING DRIVEN UNKNOWINGLY WITH THIS LEAK. TANK WAS REPLACED UNDER EXTENDED AUTO WARRANTY. MULTIPLE ELECTRICAL PROBLEMS: TAIL LIGHT GOES OUT AND IS REPLACED, THEN DRIVER HEADLIGHT GOES OUT. WATER LEAKS INSIDE DRIVERS SIDE HEADLIGHT WHEN IT RAINS. THE TAIL PLUG IN FOR TAIL LIGHT BULB HAD GOTTEN SO HOT IT HAD MELTED THE PLUG IN BOTH TAIL LIGHTS. RANDOM ELECTRICAL FAILURE WITH WINDOWS AND DOOR LOCKS OCCURRING. DASH PANEL BURNED OUT, RADIO DISPLAY BLED OUT AND RADIO THEN FAILED - WOULD NOT TURN OFF AFTER BUTTON WAS PUSHED AND HAD TO BE REMOVED FROM THE DASHBOARD IN ORDER TO AVOID DRAINING BATTERY COMPLETELY. TRACTION TIRE FAILURE WHEN ENGAGED OCCURRED IN COMBINATION WITH POWER STEERING FAILURE, CRUISE CONTROL FAILURE, AND ON ONE OCCASION COMPLETE BRAKE FAILURE. NO WARNING, NO SQUEALING, NO GRINDING, NO PULLING TO THE SIDE: JUST COMPLETE BRAKE FAILURE THAT RESULTED IN AN AUTO ACCIDENT THAT INJURED…”
