REDUCED POWER/TRACTION CONTROL LIGHT CAME ON SUDDENLY AND REDUCED CAR POWER IMMEDIATELY. THIS MADE FOR A VERY DANGEROUS SITUATION WHILE PASSING A TRUCK AND ENTERING THE HIGHWAY. THE CAR DROPPED SPEED VERY QUICKLY MAKING FOR A POTENTIALLY DEADLY SITUATION. THIS PROBLEM COMES AND GOES WITH NO WARNING UNTIL IT HAPPENS. RESEARCH SHOWS THIS IS A BIG PROBLEM FOR GM VEHICLES ESPECIALLY THE 2009 BUICK LACROSS MODELS. IT'S A DISASTER WAITING TO HAPPEN IF IT HASN'T HAPPENED ALREADY. THIS NEEDS TO BE RECALLED ASAP.

THIS HAS HAPPENED NUMEROUS TIMES. THE FIRST TIME THE CHECK ENGINE LIGHT CAME ON, I DON'T RECALL THE MESSAGE I ACTUALLY GOT; BUT I TOOK IT TO A DEALERSHIP AND THEY REPLACED AN EMISSION CONTROL ITEM WHICH SEEMED TO DO THE TRICK FOR AWHILE. EVENTUALLY, AS I WAS DRIVING ALONG SOME TIME LATER, THE MESSAGE "REDUCED ENGINE POWER" CAME UP; AND I COULD FEEL THE ENGINE IMMEDIATELY START TO DRAG. IN ABOUT 30 SECONDS TO A MINUTE, "TRACTION CONTROL OFF" OR SOMETHING SIMILAR COMES UP. I STOPPED TO LOOK AT THE MANUAL WHICH SAID TO SHUT THE ENGINE OFF, WAIT A FEW MINUTES, THEN START THE CAR AND THIS WOULD CLEAR THE CODE SO THAT THE CAR WOULD RUN NORMALLY. I DID THIS, AND I SAW THAT THE CAR WAS OPERATING MORE NORMALLY BUT THE "CHECK ENGINE LIGHT" STAYED ON. AFTER SEVERAL STOPS AND STARTS, THE LIGHT WENT OFF. THIS HAS HAPPENED MORE TIMES THAN I CAN COUNT. ON 6/3, I TOOK IT TO A DEALERSHIP BECAUSE IT SEEMED TO BE HAPPENING MORE FREQUENTLY. THE ONLY THING THEY COULD FIND THAT MIGHT BE CAUSING IT DID NOT SEEM TO BE THE PROBLEM, BUT THEY WORKED ON THE X101 CONNECTOR AND TEST DROVE IT 16 MILES W/O A PROBLEM. TWO DAYS LATER WHILE DRIVING TO WORK (AFTER DRIVING ABOUT 20 MIN.), THE SAME THING HAPPENED AGAIN. ANOTHER GARAGE WHERE I HAD MY OIL CHANGED RAN THE CODES AND FOUND THAT P1125 - FUEL & AIR METERING AND P2138 THROTTLE/PEDAL POSITION WERE LISTED. I GAVE THIS INFO TO THE BUICK DEALER TO SEE IF THE PROBLEM COULD BE FIXED. THE CAR IS NO LONGER UNDER WARRANTY EXCEPT FOR EMISSION CONTROLS, SO I PAID FOR THE WORK. THEY WERE NOT SURE THAT THE PROBLEM WAS REPAIRED. IT TURNED OUT THAT IT WASN'T. NOW, WHAT? DO I JUST KEEP TAKING IT BACK AND PAYING FOR THINGS TO BE TRIED? *TR

Official recalls

15V519000 · Exterior Lighting:headlights

Aug 14, 2015

General Motors LLC (GM) is recalling certain model year 2007 Pontiac Grand Prix, 2006-2009 Buick LaCrosse, 2006-2007 Buick Rainier, Chevrolet Trailblazer, GMC Envoy, 2006 Chevrolet Trailblazer EXT, GMC Envoy XL, 2006-2008 Isuzu Ascender, and Saab 9-7x vehicles. In the affected vehicles, the headlamp driver module (HDM) may overheat and fail, causing the headlamps and daytime running lights to not illuminate.

Consequence & remedy

Consequence: Headlamps that do not illuminate reduce the driver's ability to see the roadway and reduce the vehicle's visibility to oncoming vehicles, both of which increase the risk of a vehicle crash.

Remedy: GM will notify owners, and dealers will replace the HDM, free of charge. The recall began on May 17, 2016. Owners may contact Buick customer service at 1-800-521-7300 or Pontiac customer service at 1-800-762-2737. GM's number for this recall is 14291.

14V355000 · Electrical System:ignition

Jun 23, 2014

This defect can affect the safe operation of the airbag system. Until this recall is performed, customers should remove all items from their key rings, leaving only the ignition key. The key fob (if applicable), should also be removed from the key ring. General Motors LLC (GM) is recalling certain model year 2005-2009 Buick LaCrosse, 2006-2011 Buick Lucerne, 2000-2005 Cadillac DeVille, 2006-2011 Cadillac DTS, 2006-2014 Chevrolet Impala, and 2006-2007 Chevrolet Monte Carlo vehicles. In the affected vehicles, the weight on the key ring and road conditions or some other jarring event may cause the ignition switch to move out of the run position, turning off the engine.

Consequence & remedy

Consequence: If the key is not in the run position, the air bags may not deploy if the vehicle is involved in a crash, increasing the risk of injury. Additionally, a key knocked out of the run position will cause loss of engine power, power steering, and power braking, increasing the risk of a vehicle crash.

Remedy: GM will notify owners, and dealers will install two key rings and an insert in the key slot or a cover over the key head on all ignition keys, free of charge. The recall began on September 23, 2014. Owners may contact General Motors customer service at 1-800-521-7300 (Buick), 1-800-458-8006 (Cadillac), and 1-800-222-1020 (Chevrolet). GM's number for this recall is 14299.
