My cars coolant is leaking and the source is unknown. My car has overheated twice and my mechanic has been unable to find what needs to be repaired. The coolant has need to to be filled twice within a 6 month period. Now my car is having other issues with the catalyst system that lead me to believe the coolant leak might be affecting these other parts. My catalytic converter was already replaced and the same code has popped up 4 months later.

The car keep getting hot due to liquid missing but I always fill the car up to 2014 it was a recall to all the chef sonics but not the 2015 but is still the same issue

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.

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.

VEHICLE FELT LIKE IT WAS VIBRATING WHILE IN IDLE AND WHEN PRESSING DOWN ON THE BRAKES. THERE WAS VERY LOW ACCELERATION AND IT FELT LIKE MY CAR WAS IN NEUTRAL. I WAS DRIVING ON A CITY STREET GOING ABOUT 20-25 MPH. THE CHECK ENGINE LIGHT TURNED ON. I TOOK MY CAR IN AND HAD TO HAVE THE IGNITION COIL AND IGNITION BOOT REPLACED AT 30,345 MILES.

THE FUEL INJECTOR IS NOT WORKING PROPERLY AFTER ONLY HAVING MY CAR FOR 6MONTH.

CAR IS LESS THAN 3 YEARS OLD AND THE RADIATOR IS RUSTED/CORRODED. THIS KIND OF CORROSION SHOULD NOT HAPPEN ON A CAR LESS THAN 3 YEARS OLD. I KEPT SMELLING SOMETHING BURNING WHEN DRIVING ON THE HIGHWAY, SO I STARTED MONITORING THE COOLANT LEVELS. I WAS ADDING MORE THAN A GALLON OF COOLANT EACH MONTH.
