2012 Chevrolet Sonic Electrical System Problems

Reviving the p2138 code for throttle/accelerator sensor. Still getting code after replacing 3 accelerator peddles. Possible manufacture issue with wiring that water gets into connectors shorting out that system

We have had to deal with severe overheating issues and failing parts our entire ownership of this vehicle, both of which then cause other parts to fail, as the parts are so poorly made and heat sensitive. We have replaced the turbocharger (twice), intake manifold + valve cover (twice), catalytic converter, the radiator (THREE TIMES), the cooling fan (twice), the MAF sensor (twice), and much more. All of this has been done over the course of 18months. This has easily been the most expensive car we have ever owned due to the constant repairs, all of which has been because of Failing Parts and overheating.

After original P0011 engine code dealer bought from replaced VVT actuators, oil control solenoid, VCG, timing belt, water pump, antifreeze, idler and tensioner on 10/27 -11/21. Vehicle ran for one week and all thru Dec 2021 intermittently kept running rough and stalling and throwing P0011 code Camsgaft Position Sensor intake and P0301 cylinder 1 misfire. Smelled burning oil too. Replaced all separate throughout month -Camshaft position sensor intake, changed oil, spark plugs and now the ignition coil. Each time ran one day and code P0011 kept coming back. Running rough, poor gas mileage and stalls. Have extended warranty going back to dealer bought from.

Vehicle keeps throwing P0011 codes with engine running rough and stalling when moving from stopped or slowing down

TL* THE CONTACT OWNS A 2012 CHEVROLET SONIC. THE CONTACT STATED THAT WHILE DRIVING AT AN UNDISCLOSED SPEED, THE BATTERY WARNING LIGHT ILLUMINATED ON THE INSTRUMENT PANEL. THE CONTACT ATTEMPTED TO RESTART THE VEHICLE HOWEVER, THE VEHICLE FAILED TO RESTART. THE CONTACT PURCHASED A NEW BATTERY HOWEVER, THE FAILURE PERSISTED. THE VEHICLE WAS TOWED TO AN INDEPENDENT MECHANIC WHERE THE STARTER WAS REPLACED. DESPITE THE REPAIR, THE FAILURE PERSISTED. THE VEHICLE REMAINED IN THE POSSESSION OF THE MECHANIC. NEITHER THE DEALER NOR THE MANUFACTURER WERE NOTIFIED OF THE FAILURE. THE VEHICLE WAS NOT REPAIRED. THE FAILURE MILEAGE WAS UNKNOWN.

RADIO IS NOT WORKING. THEREFORE, I AM UNABLE TO HEAR ANY ALARMS (DOOR, BLINKER). I AM ALSO UNABLE TO USE HAND FREE CALLING OR ON STAR. ALSO, THE CAR WILL RANDOMLY ATTEMPT TO START IF THE KEY IS LEFT IN THE IGNITION.

CHECKED CAR WHILE STATIONED, WHEN RUNNING ALWAYS NEEDS MORE COOLING MAYBE ELECTRICAL BURNOUT OF A PART THAT CONNECTS TO THE RADIATOR FAN. WHEN PUT THE DIAGNOSE CODE, NONE IS GIVEN, AND TEMPERATURE GOES UP TO 225, ITS A HAZARD IF A PERSON DOES NOT KNOW THAT FAN IS NOT WORKING, PUTTING REFRIGERANT ALL THE TIME. READ THAT THERE IS A NEW RE-DESIGN COOLING FAN ASSEMBLY.

MY CAR KEEPS SHUTTING COMPLETELY OFF EVEN WHILE DRIVING, THE RADIO COME ON AND OFF BY ITSELF AND NO ONE CAN TELL ME WHY, THIS IS VERY DANGEROUS I BE DRIVING WITH MY CHILDREN IN THE VEHICLE AND THE CAR SHUTS OFF WHILE DRIVING IN TRAFFIC

HORN FAILURE. SOUNDED MY HORN AT ANOTHER VEHICLE AND THE HORN CONTINUED TO SOUND EVEN AFTER I TOOK MY HAD OFF OF IT. THIS CONTINUED ON FOR ABOUT 10 TO 15 MINUTES, INCLUDING TURNING CAR ON AND OFF, UNTIL THE POINT THE HORN COMPLETELY DIED ON IT. HORN HAS INTERMITTENTLY WORKED ON AND OFF FOR ABOUT 2 YEARS NOW. I WAS DRIVING ON A HIGHWAY ON I-55 SOUTHBOUND BETWEEN CALIFORNIA AVE AND PULASKI ROAD IN CHICAGO. THIS IS A MAJOR FAILURE AS IT IS A SMALL CAR AND LARGER VEHICLES (SUVS/SEMI-TRUCKS/ETC.) DO NOT ALWAYS SEE ME. MAKES VEHICLE VERY UNSAFE TO DRIVE.

ATTEMPTED TO START VEHICLE WITH KEY IN IGNITION AND ALSO USING THE FACTORY INSTALLED WIRELESS REMOTE STARTER WHILE CAR WAS STATIONARY HOWEVER THE CAR WOULD NOT START INITIALLY. AFTER ANOTHER ATTEMPT OR TWO THE CAR DID START. ALSO, ON OCCASION AFTER CAR DOES FINALLY START, IT IMMEDIATELY TURNS BACK OFF. HAD CAR BATTERY TESTED WHICH THAT WAS NOT THE ISSUE. TOOK THE VEHICLE TO LOCAL MECHANIC AND HE FOUND NOTHING WRONG HOWEVER WHILE THE CAR WAS SITTING IDLE WITH THE KEY IN THE IGNITION AND TURNED OFF WITH NO HUMAN INTERACTION, THE CAR ATTEMPTED TO START ITSELF 3 DIFFERENT OCCASIONS. HE RECOMMENDED TAKING CAR TO THE CHEVY DEALERSHIP AND HAVING THEM REPROGRAM AND INSPECT THE REMOTE STARTER CONNECTION/PROGRAMMING. NOW THE CHECK ENGINE LIGHT IS ON AS A NOTIFICATION AND THE ISSUE CONTINUES AFTER MUTIPLE DAYS OF REPEAT FAILED ATTEMPTS TO START WHETHER FROM ACTUAL KEY OR WIRELESS REMOTE START ATTEMPTS. WHETHER VEHICLE WAS LEFT INSIDE GARAGE OR OUTSIDE THE ISSUE IS STILL THE SAME, REGARDLESS OF TEMPERATURE.

VEHICLE WAS PARKED ON CHRISTMAS EVE 2018 AND DRAINED BATTERY. RADIO WOULD TURN OFF BUT TURN BACK ON IT'S SELF. CAUSES BATTERY REPLACEMENT. TO TO GM THEY TOOK FUSE 15 OUT NOW HAVE NO SPEAKERS ONSTAR RADIO INCOMING CALLS CRASH RESPONSE

WE HAVE 11000 MILES ON THE CAR SO WE'VE NOT EXPERIENCE MANY OF THE MECHANICAL PROBLEMS MANY HAVE, BUT OURS IS NONE LESS DANGEROUS. THE RADIO STARTED COMING ON AND OFF BY ITSELF. YOU CUT IT OFF WHEN YOU GET OUT OF CAR, THE RADIO COMES BACK ON .TURN IT OFF AND IT COMES BACK ON AND OVERNIGHT THE BATTERY GOES DEAD. STUMBLED ON THE DEAD BATTERY ISSUE AFTER I REPLACED THE BATTERY AND THE SAME THING HAPPENED AGAIN. ONCE AGAIN, THE LAST MECHANIC DIED AT THE LOCAL CHEVY PLACE.THEY SAID THEY HAVE ONE SOLUTION,REPLACE THE RADIO. THEY HAVE NO BULLETONS FROM THE FACTORY ON IT SO JUST UNDO THE AUDIO FUSE TO SAVE THE BATTERY, SO WE DID AND IT DID SAVE THE BATTERY BUT NO SOUNDS IN THE CAR NOW.AT ALL. WITH JUST 11,000 MILES WE'VE NOT YET EXPERIENCED THE HORROR STORIES ABOUT THE MOTOR AND TRANSMISSIONS BUT HAVE NOTICED, EVEN WITH LOW MILEAGE, I NEED TO ADD SOME OIL. GM CAN'T AND HAS NO DESIRE TO FIX CHEVY PROBLEMS. I THINK THIS HAS ADDED TREMENDOUSLY TO PEOPLE STOP BUYING THEIR SEDANS AND SMALL TRUCKS. IT'S NOT THERE SERVICE DEPARTMENT FAULT. IT'S A FAULTY DESIGNS AND ENGINEERING. I'VE HAD 4 UNFIXABLE MAJOR ENGINEERING PROBLEMS IN THE PAST 20 YEARS WITH THEIR VEHICLES AND THIS IS THE LAST CHEVY I'LL EVER BUY.THEY NEED TO BLAME THEIR SALES PROBLEMS ALL ON THEIR PRODUCT DESIGNS. IT'S NOT A DEALER OR SERVICE DEPARTMENT ISSUE. IT'S THE DESIGN AND ENGINEERING OF THESE DANG CARS THEY BUILD. SOME TIMES IT'S A DOG IN YOUR OWN KENNEL THAT BITES YOU. IT'S A ENGINEER IN THEIR OWN KENNEL THAT IS NOT THE SHARPEST PENCIL IN THE BOX THEY'RE HIRING TO DESIGN SYSTEMS AND ENGINEERING THEIR SYSTEMS. THEY HAVE IDLING PROBLEMS WITH THEIR COLORADO TRUCKS AND STICKING THIS 4 CYCLINDER 2.7 CU.IN MOTOR IN THEIR BIG TRUCKS, WHICH ALREADY HAS COOLING SYSTEMS DESIGN PROBLEMS, BORDERS ON LUNACY. I'M DONE WITH CHEVY.

WITH THE KEY INSIDE THE IGNITION TURNED TO THE OFF POSITION THE CAR TRIES TO CRANK ITSELF BUT WON'T ACTUALLY START OR STAY RUNNING. MY LIGHTS, RADIO ETC HAVE TURNED THEMSELVES ON AND OFF FOR NO REASON. THE CAR HAS NEVER TRIED TO CRANK WHILE DRIVING BUT THE RADIO WHILE DRIVING WILL SHUT OFF COMPLETELY. NO RADIO LIGHTS WON'T DISPLAY TIME OR ANYTHING. NOW I AM TO THE POINT WHERE I HAVE REPLACED THE BATTERY AND THE PROBLEM WAS RESOLVED, FOR A COUPLE OF WEEKS NOW I'M BACK TO THE SAME PROBLEM. UNWANTED CRANKING OF THE STARTER. THE KEY DINGING WHILE PLACED INSIDE THE IGNITION IS OBSOLETE UNLESS I WIGGLE THE KEY AROUND. SOUNDS LIKE A FAULTY IGNITION SWITCH. CAR HAS BEEN STATIONARY AND IN PARK WHILE TRYING TO CRANK ITSELF. NEVER IN NEUTRAL OR MOVING. CAR IS A 2012 CHEVY SONIC. 1.8L ECOTECH MOTOR.

THE LIGHT MY ENGINE SHOWS AND IT ALWAYS SMELL LABOR KE OIL

TL* THE CONTACT OWNS A 2012 CHEVROLET SONIC. AFTER THE VEHICLE WAS DRIVEN FOR APPROXIMATELY TEN MINUTES IN THE MORNING, THE CONTACT REMOVED THE KEY FROM THE IGNITION. THE CONTACT STATED THAT THE VEHICLE ATTEMPTED TO CRANK ON ITS OWN. THE CONTACT STATED THAT THE FAILURE ONLY OCCURRED IN THE MORNING AFTER THE KEY WAS REMOVED FROM THE IGNITION. THE FAILURE OCCURRED FOR APPROXIMATELY SIX MONTHS. THE VEHICLE WAS TAKEN TO THE DEALER (CENTENNIAL CHEVROLET IN UNIONTOWN, PENNSYLVANIA), BUT WAS UNABLE TO REPLICATE THE FAILURE. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE VEHICLE WAS NOT REPAIRED. THE APPROXIMATE FAILURE MILEAGE WAS 43,642.

THE VEHICLE'S ELECTRICAL SYSTEM IS MALFUNCTIONING, CAUSING THE SPEEDOMETER DISPLAY NOT TO SHOW UP WHEN THE CAR TURNS ON. IT'S ALSO CAUSED THE VEHICLE TO REV UP AND DOWN WHILE THE CAR IS IDLE.

TL* THE CONTACT OWNS A 2012 CHEVROLET SONIC. WHILE THE VEHICLE WAS STATIONARY WITH THE KEY IN THE IGNITION, THE VEHICLE STARTED UP WITHOUT WARNING. THE VEHICLE BEGAN TO SHAKE AND THE CONTACT STATED THAT THE AUTO-START FEATURE MAY HAVE MALFUNCTIONED. ON ANOTHER OCCASION, WHILE DRIVING 50 MPH, THE VEHICLE BEGAN TO SHAKE AGAIN AND SEEMED AS IF IT WOULD STALL. BELL PIERRE CHEVROLET IN SEATTLE, WASHINGTON WAS MADE AWARE OF THE FAILURES BY PHONE. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS MADE AWARE OF THE ISSUE AND REFERRED THE CONTACT TO THE DEALER. THE FAILURE MILEAGE WAS APPROXIMATELY 27,500.

WHEN PUTTING MY CAR INTO PARK THE GEAR SHIFT BUTTON IS NOT RELEASING THEREFORE THE CAR CAN NOT BE TURNED OFF! THE SERVICE PLACE IS CHANGING ME $315 TO REPLACE THE WHOLE GEAR SHIFT! ALSO GEAR SHIFT IS STICKING NOT WANTING TO GO INTO PARK!!!

VEHICLE STARTED TO RANDOMLY SHOW CHECK ENGINE LIGHT ON, SMELL OF GASOLINE FROM TIME TO TIME. EVERY TIME I WOULD TAKE IT IN THE LIGHT WOULD NOT BE ON SO THEY COULDN'T HELP. FINALLY LIGHT STAYED ON AND VEHICLE WOULD SHUT OFF WHILE I WOULD DRIVE, ESPECIALLY IF I HIT A STOP LIGHT. I HAD TO IMMEDIATELY TAKE VEHICLE IN AND I HAD TO RENT A RENTAL CAR SO I CAN GET TO WORK THAT MORNING. DEALERSHIP CALLED AND SAID THAT IT WAS A VACUUM ISSUE CAUSING ALL THE STALLING AND ALL THE ISSUES WITH THE MULTIPLE LIGHTS ON THE DASH. IT TURNED OUT TO BE THE AIR DUCT FOR THE AIR INTAKE BOX. THIS VEHICLE WAS VERY DANGEROUS TO DRIVE AND I HAVE SEEN SEVERAL COMPLAINTS WITH SAME ISSUE, VEHICLE IS BARELY OUT OF WARRANTY AND AT 36000 MILES BUT VEHICLE HAS LESS THAN 50K MILES. I HAD TO PAY $350.00 FOR THIS INCIDENT AND CHEVROLET WILL NOT COVER IT.
