2008 Buick LaCrosse Speed Control & Cruise Problems

ONCE IN A WHILE IT ACTS UP WHERE IT STATES THAT IT'S GOT LOW OIL PRESSURE EVEN THO IT'S GOT PLENTY OF OIL,ALSO IT HAS MISFIRED DURING WHEN THIS HAPPENS. IT'S LIKE THIS: I'M DRIVING. EVERYTHING IS FINE UNTIL ALL OF THE SUDDEN I NOTICE ENGINE LIGHT IS ON ALSO THE T/C LIGHT COMES ON AND IT ALSO STATES THE LOW OIL PRESSURE AND THE ACCELERATION PEDAL IT ACTS UP. FOR EXAMPLE, I'M GIVING GAS AND IT ISN'T ACCELERATING AS MUCH AS IT SHOULD BE AND IT TOTALLY FLUCTUATES. I'VE ALSO HAD THE CAR MISFIRE AND SHUT OFF DURING ONE OF THESE EPISODES AS WELL. THESE EPISODES OF WHAT I HAD JUST DESCRIBED COMES AND GOES AND ACTUALLY IT STAYED GONE FOR A GOOD WHILE NOW UNTIL JUST A FEW MINUTES AGO. THE GUY WHO SOLD ME THIS CAR TOLD ME THAT THERE'SA RECALL ON WHATEVER ISSUE I'M HAVING WITH THE ACCELERATOR PEDAL (I PLUGGED IN FIXD TOOL WHICH TELLS ME WHAT IS WRONG WITH MY CAR AND GIVES ME TWO CODES THE CODES BEING: P: 2138 AND CODES P: 1125.

TL* THE CONTACT OWNS A 2008 BUICK LACROSSE. WHILE DRIVING APPROXIMATELY 50 MPH, THE ACCELERATOR PEDAL DEPRESSED INDEPENDENTLY AND THE VEHICLE ACCELERATED WITHOUT WARNING. THE BRAKE PEDAL HAD TO BE DEPRESSED WITH EXTREME FORCE IN ORDER FOR THE VEHICLE TO STOP. THE VEHICLE WAS TAKEN TO A DEALER WHERE IT WAS DIAGNOSED THAT THE THROTTLE BODY FAILED AND NEEDED TO BE REPLACED AND THE ECU NEEDED TO BE REPROGRAMMED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE. THE FAILURE MILEAGE WAS UNKNOWN.

WHILE DRIVING AT 35 MPH OR 50 MPH CAR SLOW DOWN TO 10 MPHSTOPS AND WON'T ACCELERATE(GAS PEDAL IS HARD WON'T GIVE GAS) . ENGINE LIGHT COMES ON AND CHIMES SAYING REDUCE ENGINE POWER AND TRACTION IS OFF (SERVICE TRACTION). WHEN TRY TO STEER OF THE ROAD STEERING WHEEL IS HARD TO TURN. I HAVE HAD THE THROTTLE BODY CLEAN AND IT'S STILL DOING THE SAME THING. VERY DANGEROUS WHEN DRIVING AT NIGHT. GM NEEDS TO FIX ALL PROBLEM WON'T DRIVE TO DANGEROUS. CAN YOU PLEASE HELP ME PURCHASE CAR MARCH 2012. *TR

WHILE DRIVING, THE ENGINE LIGHT CAME ON, FOLLOWED SHORTLY THEREAFTER BY THE TRACTION CONTROL LIGHT.THEN THE ENGINE BEGAN TO LOSE POWER AND THE ACCELERATOR PEDAL DID NOT WORK. A NOTICE APPEARED ON THE DASH CONTROL: "ENGINE POWER REDUCED" AND "SERVICE TRACTION CONTROL". IF I HELD THE ACCELERATOR PEDAL DOWN ALL THE WAY TO THE FLOOR, AFTER ABOUT 5 SECONDS THE CAR BEGAN TO ACCELERATE QUICKLY. I COULD THEN MAINTAIN SPEED BY ALTERNATELY STEPPING ON AND RELEASING THE ACCELERATOR PEDAL QUICKLY. ACCELERATING FROM A STOPLIGHT IS A VERY SLOW AND DISRUPTIVE (TO TRAFFIC) PROCESS. THIS HAS HAPPENED MULTIPLE TIMES AND HAS FAILED SEVERAL ATTEMPTS AT REPAIR. ON SOME OCCASIONS, THE CAR HAS BEGUN TO ACCELERATE ON ITS OWN DURING THIS PERIOD OF MALFUNCTION, SUCH THAT I HAVE HAD TO RIDE THE BRAKE PEDAL. ON SOME OCCASIONS THIS PROBLEM HAS REMEDIED ITSELF AFTER A COUPLE OF DAYS, WITH TURNING THE ENGINE ON AND OFF TO REBOOT. THE PROBLEM CAN LAST FOR DAYS AT A TIME. I HAVE REPLACED THE THROTTLE BODY SENSOR TO NO AVAIL. INTERESTINGLY, I ALSO OWNED (UNTIL LAST WEEK) A 2007 LACROSSE WHICH DOES THE EXACT SAME THING, AND HAS ALSO HAD THE THROTTLE BODY SENSOR REPLACED WITH NO LUCK. I HAVE SEEN MULTIPLE DESCRIPTIONS OF THIS BY PEOPLE ONLINE, DESCRIBING EXACTLY THE SAME CONDITIONS AND WARNINGS. THIS IS A SIGNIFICANT SAFETY ISSUE WHEN IT HAPPENS, AS I CANNOT SAFELY ACCELERATE IN BUSY TRAFFIC, AND THE CAR SLOWS DOWN TO SPEEDS UNSAFE FOR THE CONDITIONS. I FIND IT DIFFICULT TO BELIEVE GM DOES NOT KNOW ABOUT THIS, IN THAT I HAVE HAD THE SAME PROBLEM WITH 2 LACROSSES. THANK YOU. *TR

WHILE TRAVELING AT APPROX 20 MPH, THE CRUISE CONTROL ACTIVATED AUTOMATICALLY WHILE TURNING INTO A PARKING LOT. THE VEHICLE SPEED UP IN A MATTER OF 2 SECONDS AND WAS AT MUCH HIGHER SPEED WHEN SHE VEERED OFF INTO A BUSH. THE QUICK SPEED ACCELERATION OF THE VEHICLE WITHOUT OUT ANY ACTIVATION BY DRIVER IS OF GREAT CONCERN. DRIVER WAS STARTLED BY SUDDEN SPEED UP OF VEHICLE. FEELS THE CRUISE CONTROL ACTIVATED ON ITS OWN. SHE DID NOT TOUCH THE CRUISE CONTROL BUTTONS ON STEERING WHEEL AT ANY TIME. OWNERS DO NOT FEEL THE LOCATION OF THE CRUISE CONTROL BUTTONS ARE LOCATED IN GOOD SPOT. THE CRUISE CONTROL HAS ACTIVATED ON ITS OWN SEVERAL TIMES OVER THE PAST 4 YRS. OWNERS HAVE HAD DEALERSHIPS LOOK AT ISSUES. THEY HAVE BEEN UNSUCCESSFUL IN DUPLICATING OR RESOLVING THIS ISSUE. COMPLAINT HAS ALSO BEEN FILED WITH GENERAL MOTORS IN 2011 CASE # [XXX]. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6). *TR
