NHTSA Complaint #11015939 — 2013 CHEVROLET SONIC

WHEN THE CAR CAME TO A COMPLETE STOP AT A STOP LIGHT THE ENGINE WAS SURGING WITHOUT APPLICATION OF THE ACCELERATOR PEDAL. THE CHECK ENGINE LIGHT CAME ILLUMINATED. WE CONTINUED DRIVING UNTIL ABOUT AN HOUR LATER WHEN THE CAR WAS PUT IN PARK IN THE DRIVEWAY THE ENGINE SURGED UNTIL I SHUT IT OFF. THE CHECK ENGINE LIGHT REMAINED ILLUMINATED AND WAS TAKEN TO THE LOCAL DEALER THE NEXT DAY. THE SERVICE ADVISOR REQUESTED WE BRING IT BACK THE FOLLOWING MONDAY. THE CHECK ENGINE LIGHT TURNED OFF WHILE DRIVING SATURDAY. DURING THE DRIVE BACK TO THE DEALER FOR THE MONDAY APPOINTMENT AND STOPPED AT A STOP LIGHT THE ENGINE RPM'S DROPPED IN HALF AND RAN ROUGH FOR A FEW SECONDS. THE RPM DECREASE AND ROUGH RUNNING HAS BEEN A LONGER TERM ISSUE THAT HAS BEEN PREVIOUSLY DIAGNOSED WITH NO RESOLUTION. I WAS ADVISED BASED ON CURRENT DIAGNOSIS THAT THE EVAP PURGE CONTROL SOLENOID NEEDS TO BE REPLACED.
