OUT OF THE BLUE, THE FOLLOWING WARNINGS APPEARED: ENGINE POWER IS REDUCED, SERVICE STABILITRAK, SERVICE TRACTION CONTROL. IMMEDIATELY MY CAR STARTED RUNNING HORRIBLY (IT DIDN'T WANT TO GO, WAS CHUGGING, AND ALMOST FELT LIKE THE TRANSMISSION WAS SLIPPING). I PARKED IT. LATER I STARTED IT AND ALL WARNINGS WERE GONE, BUT THE ENGINE LIGHT WAS ON. . THE NEXT DAY I STARTED IT AND JUST THE ENGINE LIGHT WAS ON. 3RD DAY I STARTED IT, ENGINE LIGHT STILL ON. DROVE IT TO A SHOP,.RIGHT BEFORE I PULLED IN, THE LIGHT TURNED OFF! THEY SCANNED IT ANYWAY & SAID THAT NOTHING CAME UP. THE CAR HAS DRIVEN JUST FINE, NO WARNINGS OR LIGHTS UNTIL 11/25/2020. I WAS DRIVING ABOUT 20MPH, TURNED RIGHT ON A SIDE STREET AND ALL OF A SUDDEN ALL OF THE EXACT MESSAGES AS BEFORE CAME ON. VEHICLE IMMEDIATELY STARTED RUNNING SLOW AND "CHUGGING"AGAIN. I PARKED IT. WHEN I STARTED IT AGAIN LATER, ALL THE SAME MESSAGES WERE STILL THERE. IT'S DEFINITELY SCARY WHEN THIS HAPPENS & SINCE THE 1ST TIME IT HAPPENED, I WAS NERVOUS TO DRIVE IT FAR…”
