Electrical system
31 reports3 fires1 related recall
“WAS DRIVING DOWN ROAD GOT TO MY DESTINATION PARKED IT AND WHEN I CAME OUT IT WOULD NOT START FOUND A BURNT FUEL PUMP RELAY CHANGED IT AND DROVE IT HOME. 20 MIN LATER I DROVE IT AGAIN AND MADE IT 2 MILES SAME THING HAPPENED TO RELAY ONLY WHEN I WAS DRIVING IT.”
Air bags
27 reports1 crash
“The passenger airbag light started coming on and going off intermittently. After several weeks of this, it was on every time the car is driven. Testing by an ASE certified mechanic revealed that the permanent light results in no front seat airbags. The failed part is the seat presence sensor. The part is - and hasn't been for quite a while - manufactured by GM. Aftermarket parts are costly and the installation cost is in the hundreds of dollars. Research indicates that this is a well-known and long reported issue. Why not a recall years ago? Other than brakes and steering, could there be any more unsafe components than those affecting airbags? The only remedy other than continuously replacing the faulty part, is a bypass module. If it functions correctly, the airbag will deploy regardless of passenger weight. This puts any child or underweight rider in danger. And, of course, considering the expense, many owners will do nothing with possibly grave consequences. I think you "dropped the ball" big time on this one!”
Vehicle speed control
9 reports1 crash
“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.”
Engine
5 reports1 fire
“TL* THE CONTACT OWNS A 2009 BUICK LACROSSE. WHEN THE CONTACT STARTED THE VEHICLE, THE CHECK ENGINE AND SERVICE TRAC SYSTEM WARNING INDICATORS ILLUMINATED. ALSO, THE VEHICLE WOULD NOT EXCEED 15 TO 20 MPH WHEN THE ACCELERATOR PEDAL WAS DEPRESSED. THE CONTACT TOOK THE VEHICLE TO AN INDEPENDENT MECHANIC WHERE THE ACCELERATOR PEDAL WAS REPLACED, BUT THE FAILURE RECURRED. THE DEALER WAS NOT CONTACTED. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE AND STARTED AN INVESTIGATION. THE MANUFACTURER INFORMED THE CONTACT TO CALL NHTSA TO FILE A COMPLAINT. THE FAILURE MILEAGE WAS 99,000.”
Fuel/propulsion system
5 reports
“ORIGINAL PURCHASER OF VEHICLE WITH UNDER 120,000 MILES AND HAVE A "REDUCED POWER / ACCELERATOR PEDAL POSITION SENSOR" PROBLEM AS RECALLED BY GM FOR SOME MAKE AND MODELS AS SAME, BUT NOT MINE AS IT DID NOT MANUFACTURED AT SAME PLANT AS OTHERS (AS I WAS TOLD)? I'M FINDING IT COINCIDENTAL THAT I WOULD HAVE THE SAME PROBLEM?”
