NHTSA Complaint #10863018 — 2010 BUICK LACROSSE

OVER THE PAST SEVERAL MONTHS, WHILE DRIVING, THE SERVICE STABILITRAK WARNING LIGHT COMES ON; THE ABS & PARK ASSIST LIGHTS FLASH ON AND OFF; MY RPM, SPEEDOMETER, & TEMPERATURE GAUGES GO HAYWIRE; AND THE ENGINE LOSES POWER CAUSING THE CAR TO JERK. I NEVER KNOW WHEN THIS WILL HAPPEN. ON 3/18/16, I WAS PUT IN A DANGEROUS SITUATION WHEN THIS HAPPENED WHILE DRIVING ACROSS THE STATE OF FLORIDA ON A 2 LANE HIGHWAY THAT HAD NO SAFE PLACE TO PULL OFF THE ROAD. THE CHECK ENGINE LIGHT ALSO CAME ON AND STAYED ON THRU THE REST OF MY DRIVE. TWO DAYS LATER, THE DRIVE HOME WAS INCIDENT FREE & THE CHECK ENGINE LIGHT WAS GONE. ON 3/22/16 I TOOK THE CAR TO A GM DEALER; SHOWED THE SERVICE TECH A VIDEO OF THE EVENTS HAPPENING AS I WAS DRIVING AND A LETTER I GOT FROM GM REGARDING A POSSIBLE THROTTLE SENSOR PROBLEM THAT CAUSES REDUCED POWER AND MALFUNCTION INDICATOR LAMPS TO APPEAR. THE GM DEALER TECH SAID MY CARS PROBLEMS HAD NOTHING TO DO WITH GM'S LETTER AND HE WAS 90% SURE MY FUEL INJECTOR NEEDED REPLACING. I TOOK THE CAR TO MY PERSONAL AUTO MECHANIC FOR 10+ YRS, WHO WORKS FOR A VERY REPUTABLE COMPANY, FOR A SECOND OPINION. SINCE THE CODES HAD BEEN CLEARED BY THE DEALERSHIP SERVICE DEPT AND THE CAR CHECKED OUT OK MY MECHANIC SAID TO DRIVE IT AND BRING IT BACK IF THE PROBLEMS OCCURRED AGAIN. IT RECENTLY STARTED HAPPENING AGAIN & MY CHECK ENGINE LIGHT CAME ON SO I TOOK THE CAR TO MY MECHANIC WHO FOUND MULTIPLE CODES FOR ECM & TCM LOST COMMUNICATION PCM MALFUNCTION & OTHER COMMUNICATION ISSUES. HE DROVE THE CAR AND EXPERIENCED WHAT I WAS EXPLAINING WAS HAPPENING. MY MECHANIC COULDN'T PINPOINT THE PROBLEM BUT SAID THERE WAS NO PROBLEM WITH THE FUEL INJECTION SYSTEM; THAT IT'S ELECTRICAL. HE SUGGESTED WE TAKE THE CAR TO ANOTHER BUICK DEALER TO HAVE IT CHECKED OUT. THIS IS A VERY DANGEROUS SITUATION & I DON'T FEEL SAFE DRIVING THE CAR SINCE I NEVER KNOW WHEN THE PROBLEMS WILL START HAPPENING.
