2014 GMC ACADIA Vehicle Speed Control Problems

Got onto the interstate and suddenly my car stopped but didn’t kill. My traction control light said off and then it said reduced engine power and my fuel went down to E. I couldn’t go but my car was still running. I killed it then waited a minute and started it again and it started moving slowly. Then it said service stabliltrak and traction system but since the light have went off. Around the same time I started hearing popping and crackling sounds from my speaker and now I have no interior sound at all just popping sounds no matter if my car is started or not. I’m scared it’s going to catch on fire or something

8/28/18 - VEHICLE UNEXPECTEDLY HAD JERKING/SHAKING AT AROUND 40MPH WITH VARIOUS SERVICE MESSAGES - STABILITRAK, TRACTION ON, TRACTION OFF, AND ALL WHEEL DRIVE. TRACTION SKID LIGHT ILLUMINATED. ONCE ABOVE 40 MPH, NO MORE JERKING. SPEEDOMETER WAS FLYING UP AND DOWN INTERMITTENTLY AS WELL. ONCE PARKED AND SHUT OFF FOR AN HOUR, I STARTED VEHICLE AND NO ISSUES. DROVE IT TO REPAIR SHOP AND THEY WERE UNABLE TO REPLICATE THE ISSUE. IT DEFINITELY FELT LIKE THE VEHICLE WANTED TO STALL. NOW I'M NERVOUS TO DRIVE IT BECAUSE I'M SURE IT WILL HAPPEN AGAIN UNEXPECTEDLY. THIS OCCURRED ON LOCAL STREETS WITH 45 MPH SPEED LIMITS.

CAR ONLY HAS 52,000 MILES ON IT AND THE ABS, BRAKE AND TRACTION LIGHTS HAVE REPEATEDLY COME ON. THE ISSUES HAS CAUSED THE LOST OF CRUISE CONTROL AND HIGH RISE OF MY ABS SYSTEM NOT WORKING DUE TO A WHEEL SPEED SENSOR FAILING. THE CAR SHOULDN'T HAVE THIS ISSUE WHEN THIS LITTLE OF MILEAGE ON IT. THE CAR STARTED THIS ALL OF SUDDEN AS I WAS DRIVING ONE DAY WHEN I WAS DRIVING IT ON THE STREET AND ONCE THE CAR IS IN GEAR ON ANY STREET SURFACE. THE RISK OF LOSING MY ABS HAS CAUSED MY NOT TO WANT TO DRIVE IT. I AM NOT THE ONLY PERSON WITH THIS ISSUE. MANY HAVE REPORTED ON DIFFERENT FORUMS OF THIS ISSUE AT A LOW MILEAGE. NO CAR SHOULD HAVE THIS SENSOR ISSUE "IF THAT IS WHAT IT TRULY IS" AT THIS YEARLY OF ITS LIVE SPAN AND LOW OF MILEAGE.

THROTTLE BODY REPLACEMENT: CHECK ENGINE LIGHT COMES ON WHILE DRIVING THE VEHICLE, THEN A MESSAGE DISPLAYING "ENGINE POWER REDUCED, SERVICE STABILITRAK." THEN VEHICLE IMMEDIATELY SLOWS DOWN AND CANNOT TRAVEL ABOVE 30 MILES PER HOUR. TOOK IT IN TO THE LOCAL GMC DEALER SERVICE DEPARTMENT, WHO PULLED THE CODE INDICATING IT WAS A THROTTLE BODY ISSUE. CHARGED US $120 TO CLEAN THE THROTTLE BODY, ONLY TO HAVE THE PROBLEM RESURFACE HOURS LATER. NOW WAITING FOR REPLACEMENT THROTTLE BODY PART TO ARRIVE, WHICH THEY INSIST WILL SOLVE THE PROBLEM FOR ROUGHLY $350 PARTS AND LABOR. SHOP ALSO INFORMED US PROBLEM CAN BE TEMPORARILY CIRCUMVENTED BY TURNING OFF THE VEHICLE, THEN TURN IT BACK ON. OFTEN THE ENGINE WILL NO LONGER BE IN REDUCED POWER MODE FOR ANYWHERE FROM 5 TO 20 MINUTES, THEN WILL THROW THE MESSAGE AND REPEAT THE ISSUE. *TR

WHILE I WAS DRIVING MY CAR IN TRAFFIC, THE GREEN CAR INDICATOR LIGHT CAME ON AND SLOWED DOWN MY SPEED TO A COMPLETE STOP. I PULLED OVER AND ALLOWED CARS TO GO AROUND ME AS I TRIED TO RESTART THE VEHICLE, 3 TIMES, AND IT WOULD NOT START. I CALLED ONSTAR TO SEE IF THEY COULD DO A CAR CHECK AND TOLD ME NOTHING WAS WRONG. AFTER AN HOUR OF BEING STUCK ON THE SIDE OF THE ROAD WITH A CAR THAT WOULD NOT START, ONSTAR GOT ME A TOW TRUCK AND TOWED ME TO THE DEALER SHIP. THE DEALER SHIP AT FIRST COULD NOT FIGURE OUT WHAT WAS WRONG WITH THE CAR AND TRIED TO SEE IF IT WAS THE INDICATOR LIGHT, AFTER 3 DAYS THE CALLED ME AND INFORMED ME THAT THE BATTERY HAD A BAD CELL WHICH HAD CAUSED THE CARS SYSTEM TO SHUT DOWN IMMEDIATELY WHILE...
