2011 Buick Lacrosse Driver assistance Problems

When going around town or on the highway the steering wheel will start shaking badly and when going to break even after the breaks have been changed the parking break will not stay on and the steering wheel will start shaking horribly to the point where your might crash your car I have had the car looked at multiple times by different manufacturers dealerships and auto shops and they all say to Change the breaks I tell them that I had them changed by Buick and Chevrolet of Dan Cummins where I had got the car and they done the same thing over again as when I bought the car

I noticed today as I was stopped at a red light with my foot on brake the vehicle was kinda jumping like it was trying to go while foot was on brake. I drove a little further and the service stabilitrak light came on followed by the reduced engine power. The car proceeded to die in the middle of a busy street. After a few minutes it did restart and I was able to get it home. This seems to be a common problem with 2011 buick lacrosse. Ihave seen several complaints about this same issue.

JULY 23, 2019 -I WAS ON THE HWY FOR APPROX. FOUR HOURS WITH MY NIECE WHEN SUDDENLY MY CAR CREATED A LOUD SOUND AND I LOST POWER AND CONTROL OF MY CAR INCLUDING MY BRAKES. I WAS TRAVELING AT 70 MILE PER HOUR. LUCKILY, TWO CARS HAD JUST PASSED ME WHEN THIS OCCURRED OTHERWISE I COULD HAVE HAD A VERY SERIOUS ACCIDENT. I WAS ON THE LEFT LANE AND WAS ABLE TO COAST TO THE SHOULDER. THE HWY. WAS FLAT AND I WAS ABLE TO COAST TO A STOP. THE ENGINE WOULDN'T START, BUT AFTER APPROX. FIVE MINUTES IT STARTED BUT I WASN'T ABLE TO MOVE. THE CAR IDLED EXTREMELY ROUGH. THE ELECTRONIC STABILITY CONTROL (ESC) LIGHT AND THE CHECK ENGINE LIGHTS WERE ON. I WAITED FOR A TOW TRUCK IN 96 DEGREE WEATHER FOR TWO HOURS BEFORE I WAS ABLE TO GET A TOW TO A GARAGE 40 MILES AWAY. THIS HAPPEND ON TUESDAY. I LEFT MY CAR AT THE BUICK DEALER AND LEFT THE KEY IN THE DROP BOX. I WAS TOLD WEDNESDAY MORNING THAT THEY WOULDN'T BE ABLE TO LOOK AT IT UNTIL TODAY (THURSDAY), SO I HAVE NO IDEA AS YET WHAT DAMAGE HAS OCCURRED TO THE ENGINE. I HAVE ONLY 53,000 MILES ON THE VEHICLE AND IT IS A 2011 MODEL. HOW COULD SOMETHING LIKE THIS HAPPEN?

DRIVING 60 MPH ON THE HIGHWAY. SUDDENLY THE INFORMATION PANEL FLASHED STABILITRAK SERVICE REQUIRED (OR SIMILAR) THEN LOW POWER MODE. CAR WENT FROM 60 TO 30 MPH ON THE HIGHWAY. UNABLE TO SPEED UP. NEEDED TO PULL OVER TO THE SIDE OF THE ROAD. TURNED CAR OFF. TRIED TO RESTART AND IT WOULDN'T RESTART FOR SEVERAL TRIES. RESTARTED AND STILL SAID LOW POWER AND WAS IDLING LOW. TRIED AGAIN AND WAS NORMAL. THIS HAS HAPPENED SEVERAL MORE TIMES AND ALWAYS IS SIMILAR. SOMETIMES IT DOESN'T HAPPEN AT ALL IN A 30 MILE TRIP, SOMETIMES IT HAPPENS 3 TIMES. VERY DANGEROUS! COULD BE REAR ENDED! I HAVE READ MANY OTHER ACCOUNTS OF THIS HAPPENING IN THE 2011 BUICK LACROSSE. AFTER THIS THE CHECK ENGINE LIGHT STAYED ON. WHEN I HAD THE AUTO PARTS STORE RUN DIAGNOSTICS IT FLAGGED MULTIPLE MISFIRES, THROTTLE POSITION SENSOR 3 TIMES, POWER CONTROL MODULE INDICATOR, TRACTION CONTROL. IT SEEMS THIS IS A FLAW IN THIS CAR. I ATTEMPTED TO GET A PICTURE OF THE SATBILITRAK SENSOR INDICATOR LIGHT, BUT IT FLASHES ON AND OFF PRETTY QUICKLY AND YOU NEVER KNOW WHEN IT WILL HAPPEN.

MY CAR STATED THAT MY TRAKSTABILTY SYSTEM NEEDED TO BE SERVICED THEN REDUCED ENGINE POWER LITE UP. CAR WOULD NOT SHIFT AND WOULD NOT INCREASE IN SPEED OVER TWENTY MILES PER HOUR. I HAD TO PULL OVER AND TURN MY CAR OFF LEAVE IT PARKED UNTIL I COULD GET IT TO THE DEALERSHIP. THE THROTTLE BODY WAS DEFECTIVE. THIS HAS HAPPENED ON OTHER 2011 LACROSSES AND THEIR IS A SPECIAL SERVICE BULLETIN WITH FREE REPAIR BUT FOR SOME REASON NOT IN MINE. I HAD TO PAY 500 DOLLAR TO REPLACE THIS. MY CAR ONLY HAS 74000 MILES ON IT AND I COULD HAVE BEEN INJURED IF I WASN'T IN A PLACE WHERE I COULD TURN MY VEHICLE OFF SAFELY.
