1ST AT 20K MILES (2019) MY CAR WOULDN'T START, STUCK LATE NIGHT. CALLED AAA, BATTERY HAD DEAD CELL SO I PURCHASED ONE FOR $200. MONTHS LATER FOUND OUT IT WAS COVERED UNDER THE WARRANTY. I STARTED SMELLING COOLANT (2019). DEALER SAID IT WAS THE WATER PUMP. IT WAS COVERED UNDER WARRANTY. STARTED SMELLING COOLANT AGAIN (2019), IT WAS A VALVE, WASN'T COVERED. THE CAR WOULDN'T START, DEAD CELL IN THE BATTERY AGAIN (2020) STARTED SMELLING COOLANT (2020), NEEDED A NEW RADIATOR, WASN'T COVERED UNDER WARRANTY. STARTED SMELLING FUMES & HAD A LEAK. IT WAS THE PURGE SOLENOID NEEDED REPLACING, ANOTHER $500. TWO MONTHS AGO (NOV 2020) THE AMBIENT SENSOR WENT OUT $450. NOW TODAY (JAN 5, 2021) THE AIRBAG LIGHT IS ON AND I'M TOLD IT'S THE INTERNAL SDM FAULT AND WILL BE CLOSE TO A $900 REPAIR.

WHILE DRIVING MY CAR "GLICHES" THE LIGHTS GO ON AND OFF, THE POWER STEERING STOPS THE LOCKS GO UP AND DOWN AND ALL ELECTRONICS IN THE DASHBOARD GO ON AND OFF. LAST WEEK, IT SHUT DOWN IN THE MIDDLE OF THE ROAD AND I COULD NOT START IT FOR ABOUT 5 MINUTES OR SO. GOT IT HOME AND IT DID IT AGAIN THE NEXT DAY WHILE IT WAS PARKED. THIS STARTED YEARS AGO. BROUGHT IT TO DEALER THEY SAID "WELL IT'S NOT DOING IT NOW". I WAS NOT EDUCATED AT THE TIME TO PUSH FOR ANYTHING TO BE DONE. THE STOPPING COMPLETELY WHILE DRIVING THAT HAPPENED LAST WEEK.

I HAVE HAD MY VEHICLE IN THE SHOP MULTIPLE TIMES SINCE I HAD IT. FIRST THERE WAS A SMELL OF COOLANT IN THE CABIN. ALTHOUGH MISDIAGNOSED INITIALLY, THE MEACHANIC LATER FOUND THAT THERE WAS TRULY AN ISSUE WITH THE CAR. BUT IN THE LAST YEAR I HAVE HAD TO HAVE THE THERMOSTAT REPLACED, THE HOUSING OF SOMETHING WAS REPLACED A MONTH LATER (I DO NOT REMEMBER THE NAME OF THE PART). AND A THIRD REPAIR WAS ALSO DONE. ALL FOR THECOOLANT THAT CONTINUES TO FIND A WAY TOLEAK OUT. NOW I AM BEING TOLD AGAIN, BY THE DEALER, THAT THE COOLANT IS LEAKING AGAIN, THIS TIME FROM THE WATER PUMP. I HAVE PAID A NICE CHUNK OF CHANGE TO AND BEING TOLD I NEED TO SPEND YET ANOTHER $400+. I HAVE OWNED MANY CARS AND NEVER HAD THIS ISSUE. I WAS ALSO TOLD BY THE DEALER THAT MANY PEOPLE WITH SONICS ARE HAVING THE ISSUES WITH THE COOLING SYSTEM. I ASKED ABOUT A RECALL AND HE TOLD ME TO MAKE A COMPLAINT. WHENEVER THE ISSUE ARISES AGAIN THERE IS ALWAYS A STRONG SMELL OF COOLANT IN THE CABIN OF THE CAR. THEN THE CAR STOPS BLOWING HEAT AND AIR, OR BLOWS IT INTERMITTENTLY.

IF YOU ARE DRIVING IN THE RAIN AND YOU HAVE YOUR HIGH BEAMS ON THE DOORS WILL UNLOCK. THE WIPERS WILL TURN OFF, THE RPM'S RACE HIGH ACCELERATING THE CAR INTO ALMOST A SPIN IF YOU DO NOT COUNTER CORRECT THE STEERING. THE ENGINE AND RADIO SHUTS OFF AT RANDOM TIMES AS WELL. HAD A DIAGNOSTIC CHECK DONE, NOTHING WRONG WITH THE ENGINE, ELECTRICAL SYSTEMS, BATTERY OR ALTERNATOR. WAS TOLD IT IS A MANUFACTURER IS WITH THE COMPUTER SYSTEM, BUT NHTSA WILL NOT ADDRESS THE ISSUE UNTIL SOMEONE GET'S KILLED, SO GENERAL MOTORS WILL NOT FIX IT, UNTIL THEY ARE IN PROBATE COURT. AS A LEO THIS IS UNACCEPTABLE BEHAVIOR, ESPECIALLY AFTER OUR GOVERNMENT JUST BAILED THEM OUT AGAIN WITH OUR TAX MONEY. *TR

PASSENGER SIDE AIRBAG SENSOR LIGHT IS INCONSISTENT. WITH ANY PASSENGER SEATED THE "ON" LIGHT DOES NOT STAY ON. IT WILL SOMETIMES COME ON TEMPORARILY THEN OFF AGAIN. THIS HAPPENS WHETHER OR NOT THE CAR IS IN MOTION. I HAVE NOTICED NUMEROUS SIMILAR CONCERNS FROM OTHERS ON LINE AND EVEN ON THIS SITE.

I PURCHASED MY CAR ABOUT A YEAR A HALF AGO AND IT HAS BEEN GIVING ME NON STOP ENGINE AND LEAK ISSUES. I HAVE A 2015 CHEVY SONIC TURBO AND SO FAR I HAVE TAKEN IT TO THE MECHANIC 8 TIMES TO FIX COOLANT LEAKS, FIX MY FUEL THERMOSTAT AS WELL AS REPLACE A HEAD GASKET AFTER HAVING IT BLOW.

THE PASSENGER SIDE (OCCUPANT SENSOR) AIR BAG SWITCH IS INCONSISTENT. IT WILL NOT ALWAYS TURN ON WHEN A PASSENGER IS IN THE SEAT. SOMETIMES IT DOES SOMETIMES IS DOES NOT.

NHTSA ODI 11291833

THERE IS A PROBLEM WITH THE PASSENGER PRESENCE MODULE ACCORDING TO OUR MECHANIC. WHEN AN ADULT IS SEATED IN THE PASSENGER SEAT WITH THE CAR TURNED ON AND STATIONARY, SOMETIMES, THE AIRBAG SYSTEM DOES NOT TURN ON AS IF IT DOES NOT RECOGNIZE A PERSON THERE. IF THE CAR IS THEN PUT INTO DRIVE, THE AIRBAG SYSTEM STILL REMAINS OFF. OTHER TIMES, THE AIR BAG SYSTEM WILL TURN ON AT THE BEGINNING OF THE DRIVE AND THEN TURN OFF RANDOMLY DURING THE DRIVE WHILE SOMEONE IS STILL SITTING IN THE PASSENGER SEAT. THIS SEEMS TO BE AN OBVIOUS ISSUE AS THE AIRBAG MAY NOT ACTIVATE IN AN ACCIDENT WHEN THERE IS INDEED SOMEONE IN THE PASSENGER SEAT.
