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.

Purchased 2012 Chevy Sonic for my son so that he can drive around as he is a student driver. Purchased on July 27th and pickup on the 29th on 30th Morning driving the car on the highway the car stopped while in drive mode and luckily no accident. reached out to the dealer i towed the car to dealership. First they told me is ready nothing wrong and said there is a problem with the key they didn't program it i picked up the car on august 2nd and while driving 5 miles it was doing stalled on the Highway near Natick Mall the Natick police came and tried to move the car to safe spot. since 12 day the car is with them on 10 August they told me that they are taking to Chevy dealership on the 11th and received a call from Dealership on 14th that they...

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

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.

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.

FIRST PROBLEM STARTED WHEN RADIO REMAINED ON AFTER KEY REMOVED FROM IGNITION. RADIO WOULD TURN ON AND OFF WHEN CAR WAS OFF AND DRAINED NEWLY REPLACED BATTERY. ADVISED TO REMOVE FUSE AS TEMPORARY FIX. CAR WAS ALSO LOSING POWER WHEN HIGHWAY DRIVING (UP TO 70 MPH). I DON'T SPEED, BUT CAR STRUGGLED TO GO ABOVE 70 MPH. THOUGHT I SMELLED SOMETHING BURNING, HAD RADIATOR CHECKED, OIL CHANGED, FLUIDS ADDED AT BEGINNING OF OCTOBER. THREE WEEKS LATER ON CITY STREET, SLOWING FOR TRAFFIC WHEN CAR LOST POWER. WHEN TRAFFIC STARTED MOVING, CAR CONTINUED TO SLOW TO COMPLETE STOP IN THE STREET DESPITE STEPPING ON GAS. WAITED 25 MINUTES FOR TOW, BUT WHEN TOW DRIVER CAME, CAR WAS ABLE TO START AND MOVE. LESS THAN AN HOUR LATER, THE PROBLEM HAPPENED AGAIN AND CAR WAS TOWED. AT MECHANIC, COMPUTER CODES INDICATED LOW/NO TRANSMISSION FLUID (EVEN THOUGH FLUID WAS ADDED AT OIL CHANGE...

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.

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

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

THE SHIFT LEVER BUTTON WILL NOT RELEASE WHEN IN PARK, SO THE VEHICLE DOESNT NOT READ THAT ITS FIRMLY IN PARK; THE KEY WONT RELEASE AND I CANNOT TURN OFF THE VEHICLE UNTIL THE BUTTON UNJAMS ITSELF OR I LUBRICATE IT TO DO SO. THIS HAS BEEN HAPPENING FREQUENTLY. THE ONLY FIX IS REPLACING THE ENTIRE SHIFT LEVER, WHICH IS UPWARDS OF $300

WHILE DRIVING MY CAR, THE CAR LOOSES POWER AND BEGAN TO STALL. I'VE WENT TO TWO CHEVY DEALERSHIPS AND TWO REPAIR AND NO ONE IS ABLE TO TELL ME WHAT'S THE PROBLEM

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....

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...

FIRST ISSUE WAS ELECTRICAL ISSUES (BAD LIGHTS, UNFUNCTIONING CONTROLS, AC ADAPTER WOULD NOT GIVE POWER, OUTSIDE LIGHTBULBS DO NOT LAST, HEADLAMP CONTROLS FELL APART, MIRROR CONRTROLS FELL OFF, VENT CONTROLS FELL APART. WHEN ELECTRIC WINDOW CONTROL STOPPS WORKING AND HISSES AND SMOKES WHEN ENGINE IS TURNED ON. I ALSO HAVE BEEN SHOCKED PAINFULLY WHEN TRYING TO GET THE AC ADAPTER TO WORK. NEXT CAME REPAIR OF THE IGNITION SWITCH.. I COULD NOT PASS STATE INSPECTION BECAUSE MY "CHECK ENGINE" LIGHT WAS ON. IN AUGUST 2017, CAR HAD ENGINE MISFIRE, WHICH COST ME REPAIR ON THE FUEL PUMP. A FEW DAYS AFTER THAT, THE BATTERY DIED AND I REPLACED IT. ONE WEEK LATER,, IT STARTED TO SMOKE UNDER THE HOOD AND THE CAR WAS OVERHEATING. THEN A FEW HOURS LATER, ELECTRIC WAS ON AND OFF BUT POWER TO VECHICLE STOPPED.. THIS ENDED UP BEING THE SERP. MAIN BELT. NEXT CAME THE...

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

WE DO CONSTANTLY ARE REPLACING PARTS WE REPLACED THE WINDOW REGULATOR AND NOT EVEN A FEW MONTHS WE HA FT TO REPLACE AGAIN THE COOLING LINES ARE CONSTANTLY GOING OUT THERMOSTAT HAS BEEN REPLACED TWICE NOW WITHIN 2 YRS THE SEAT WARMERS NO LONGER WORK BEEN LIKE THAT THE KEY GETS STUCK IN THE IGNITION HAD TO REPLACE HOSES TWICE CONSTANT GRINDING SOUNDS AND NO BODY CAN FIGURE OUT WHY THE CAR IS A TOY CAR EVERYTHING BREAKS DOWN AND NOT JUST ONCE

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.

MY WIFE AND I W'ER HIT BY A PERSON THAT RAN A RED LIGHT THE CAR WAS TOTTLED OUT WITH MAJOR FRONT END DAMAGE NO AIR BAGS DEPLOYED AT ALL WHEN THE SIDE AIR BAGS SHOULD HAVE DEPLOYED BUT DIDNT CAUSING MY WHOLE SIDE AND HEAD SMASHING INTO THE SIDE DRIVER DOOR

THERE IS NO HEAT IN MY 2012 SONIC, THE HEAT IS TURN TO THE HIGHEST POSITION BUT ONLY BLOWS COLD AIR. OCCATIONALLY THE HEAT WILL START BUT WHEN THE CAR IS NOT IN MOTION THERE IS NO HEAT AND ONLY COLD AIR.

CAR WILL START BY ITSELF AFTER KEY IS PARTIALLY INSERTED INTO IGNITION AND CAR WILL TRY TO START OVER AND OVER IF LEFT IN IGNITION WHEN TURNING OFF. TOOK TO DEALER THEY BLAMED ON AFTERMARKET RADIO. HOWEVER, I AM PRETTY SURE HAS DONE ALMOST FROM THE POINT PURCHASE. DISCONNECTED RADIO STUFF AND STILL DOES SAME THING. CAR IS STATIONARY IN PARK. NO SAFETY ISSUE OTHER THAN WHAT IS STATED.

POWER STEERING WAS NOT WORKING AS I WAS LEAVING THE HOUSE, SO I HAD THE CAR TOWED TO THE DEALER. MECHANIC SAID THE VOLTAGE FROM THE BATTERY WAS SPORADIC AND PRONE TO SPIKING. THIS SPIKING CAUSED THE POWER STEERING TO FAIL, AS THIS VEHICLE HAS NO SURGE PROTECTOR TO PROTECT ELECTRONIC CHIPS. BATTER ACID HAD ALSO SPILLED OUT OF BOTH HEAD MOUNTS CAUSING MINOR DAMAGE TO OTHER PARTS UNDER THE HOOD.

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...

AIR BAG LIGHT ON DASHBOARD CAME ON, INTERMITTENTLY AT FIRST, NOW PERMANENTLY. THERE ARE THREE (3) AIR BAG RELATED RECALLS FOR 2012 CHEVROLET SONICS WHICH DETAIL THE SAME SYMPTOMS. NEAREST CHEVROLET DEALER SAID THIS SONIC IS NOT PART OF ANY OF THOSE RECALLS BUT THE PROBLEM SEEMS TO BE THE SAME. IS THERE ANY RECOURSE TO HAVE THE CAR CHECKED AT NO COST TO OWNER? THANK YOU.

MY RADIO STAYS ON IN MY 2012 SONIC EVEN AFTER THE CAR IS TURNED OFF. THE FIRST TIME IT HAPPENED I WENT OUT TO START MY CAR IN THE MORNING AND IT WAS COMPLETELY DEAD. THE CAR WAS JUMPED AND STARTED UP FINE. I DROVE THE CAR FOR A FEW DAYS WITHOUT INCIDENT THEN I NOTICED THE RADIO WAS COMING ON AND OFF AS I WAS DRIVING. EVEN AFTER IT WAS TURNED OFF, IT WOULD JUST START PLAYING. I CONTACTED THE DEALER WHERE I PURCHASED MY CAR AND SCHEDULED AN APPOINTMENT. TWO DAYS BEFORE MY APPOINTMENT THE CAR BATTERY WAS COMPLETELY DRAINED AGAIN IN THE MORNING. ( AN EXTREME INCONVENIENCE AND ANNOYANCE IF YOU NEED TO BE TO WORK ON TIME). AGAIN THE CAR WAS JUMPED AND STARTED RIGHT UP. THE DAY BEFORE THE APPOINTMENT THE RADIO WAS COMING ON AND OFF WITHOUT ME TOUCHING IT. I WAS SO ANNOYED...

1. CAR LOSES POWER WHEN ACCELERATING/HESITATION - SOMETIMES ALMOST FEELING LIKE THE CAR WILL SHUT DOWN. IT'S RANDOM BUT HAPPENING MORE OFTEN. CAR WAS REPAIRED ONCE ALREADY FOR THIS, WAS BETTER FOR ABOUT 3-4 MONTHS AND NOW IS DOING IT AGAIN. EXTREMELY DANGEROUS WHEN MERGING ONTO HIGHWAYS OR MAKING RIGHT TURNS ON RED OR SWITCHING LANES. 2. WIPER FLUID WAS NOT WORKING, RECALL ISSUE, BUT NOT ON MY CAR. REPAIRED ONCE AND NOW NOT WORKING AGAIN! 3. SOMETHING'S WRONG WITH ELECTRICAL SYSTEM, STEREO CHANGING STATIONS, TURNING ITSELF ON AND OFF, VERY LOUD SCREECHING SOUNDS OCCASIONALLY, REPAIRED WITH AN UPDATE BUT STILL HAPPENING. 4. VERY STRANGE SOUNDS COMING FROM SUSPENSION, IT STARTED WHEN BACKING UP I WAS TOLD THEY COULD NOT FIND A PROBLEM 2 TIMES, HOWEVER, NOW IT'S HAPPENING WHILE DRIVING, IN REVERSE AND IT'S GETTING WORSE! 5. STEERING IS VERY DIFFICULT ON A WINDY DAY WHEN ON THE HIGHWAY....

TL* THE CONTACT OWNS A 2012 CHEVROLET SONIC. THE CONTACT STATED THAT AFTER THE VEHICLE WAS PARKED AND THE KEYS REMOVED FROM THE IGNITION, THE VEHICLE ATTEMPTED TO RESTART INDEPENDENTLY AND THE CHECK ENGINE LIGHT ILLUMINATED. THE FAILURE RECURRED ONCE. THE VEHICLE WAS NOT TAKEN TO A DEALER OR REPAIRED. THE MANUFACTURER WAS NOTIFIED OF THE ISSUE. THE FAILURE MILEAGE WAS UNKNOWN. THE VIN WAS NOT AVAILABLE.

MY RADIO WILL TURN ITSELF ON HOURS AFTER MY CAR HAS BEEN TURNED OFF. I'VE HAD TO TAKE OUT THE FUSE EVERYTIME I EXIT THE CAR SO THE BATTERY WON'T DRAIN. I DON'T KNOW WHERE TO BEGIN WITH FIXING THIS PROBLEM. IT'S BEEN GOING ON FOR A FEW WEEKS NOW. I'VE CALLED TO THE DEALERSHIP WHERE THE CAR WAS PURCHASED AND THEY SAID IT WAS A MANUFACTURING PROBLEM. PLEASE DON'T TELL ME I HAVE TO PAY FOR THIS OUT OF POCKET. FROM WHAT I'VE SEEN THERE'S A LOT OF THESE CASES ON THE INTERNET. SO IT'S NOT JUST A RANDOM PROBLEM.

I AM OWNER OF 2012 CHEVY SONIC, YESTERDAY AGAIN - WHEN I SHUT OFF MY CAR ...IT STARTED BACK UP AGAIN JUST AFTER I SHUT THE KEY OFF CAR WAS IN PARK. PLZE DO H E L P - M E !!!

THE BUTTON TO RELEASE THE CAR OUT OF GEAR, AND ONCE IN PARK THAT RELEASES THE KEY CAME APART. IT HAS BEEN STICKING FOR AWHILE THEN ALL OF A SUDDEN, SOMETHING SHARP STARTED POKING OUT OF THE BOTTOM OF THE BUTTON, AND IT HAS CUT MY HUSBAND'S HAND. NOW THE BUTTON BARELY PUSHES IN AND THE CAR IS VERY HARD TO GET OUT OF PARK. *TR

FIRST OF ALL THE WINDSHIELD WIPER LINE KEEPS POPPING OF MY CAR NOT ALLOWING ME TO USE MY WINDSHIELD WIPER FLUID SO THE TANK IS ALWAYS EMPTY. SECOND WHILE DRIVING MY CAR RADIO FLICKERS ON AND OFF AND SOMETIMES COMPLETELY GOES BLACK NOT ONLY THAT MY CAR SPEEDOMETER IS ELECTRICAL AND AFTER 30 MIN OF DRIVING SAYS IM GOING 20/34/WHATEVER MPH IT WANTS TO READ WHEN IM REALLY GOING THE HWY SPEED LIMIT AND I HAVE OFTEN HAD TO MESS WITH THE WIRES THAT RUN TO MY BATTERY TO TURN MY CAR BACK ON SINCE ITS THE WIRES(ELECTRICAL WORK AND NOT THE BATTERY) MY BATTERY HAS BEEN TESTED MANY TIMES. FINALLY THIRD THE LITTLE SHIFT BUTTON ON MY CAR KEEPS STICKING AND WONT ALLOW FOR MY CAR TO PROPERLY SHIFT CAUSING MY CAR TO OVER REV AND NOT WANT TO DRIVE. IM NOW AT 115,000 MILES AND EVERY TIME I...

TL* THE CONTACT OWNS A 2012 CHEVROLET SONIC. THE CONTACT STATED THAT WHILE DRIVING AT VARIOUS SPEEDS, THE VEHICLE WOULD SUDDENLY SHUT OFF. THE VEHICLE WAS TAKEN TO THE DEALER. THE TECHNICIAN DIAGNOSED THAT THE BATTERY CONNECTION WAS FAULTY. THE VEHICLE WAS REPAIRED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS 13,500. UPDATED 10/14/14*LJ UPDATED 3/31/2015 *JS

THE SHIFTER BUTTON/KNOB ALWAYS GETS STUCK. THIS VEHICLE HAS AN AUTOMATIC TRANSMISSION SO IT WASN'T INCLUDED IN THE PRIOR RECALL REGARDING THE SHIFTER. THE CAR RADIO TURNS ON BY ITSELF AFTER I HAVE REMOVED BY CAR KEY AND LOCKED THE DOORS. THIS HAS CAUSED THE BATTERY TO DRAIN AND NOW IT NEEDS TO BE REPLACED. CHEVY DEALER SAID THAT REPLACING THE SHIFTER "MAY" CORRECT THE ISSUE WITH THE RADIO. I WOULD LIKE TO KNOW WHY THE SHIFTER NEEDS TO BE REPLACED AFTER ONLY 2 YEARS OF USE. I HAVE HAD MUCH OLDER CARS WITH FAR LESS ISSUES AND NEVER NEEDED TO HAVE A SHIFTER REPLACED. IT APPEARS TO BE A DEFECT THAT THEY HAVE NOT RECALLED YET. *TR

AUTOMATIC SHIFTER BUTTON STICKS WHICH DOESN'T LET THE KEY TO COME OUT. IT'S VERY DANGEROUS DRIVING WHILE THE BUTTON IS STUCK IN. YOU CAN BUMP THE SHIFTER N IT'LL TAKE IT OUT OF GEAR DUE TO THE SHIFTER BUTTON STICKING N NOT POPPING OUT. *TR

MY VEHICLE HAS BEEN A NIGHTMARE. IN JANUARY I VISITED THE DEALERSHIP BECAUSE MY HEATER WAS NOT WORKING. AT THAT TIME I WAS TOLD I WOULD NEED TO REPLACE MY BATTERY SOON THAT IT HAD SOME LEAKING ACID. THREE WEEKS LATER I REPLACE THE BATTERY. AT THAT TIME THE DEALERSHIP INSTALLED A NEW BATTERY AND SENT ME ON MY WAY. IVE SPENT THOUSANDS SINCE THEN REPAIRING WHAT THE DEALERSHIP DESCRIBED AS A ELECTRICAL NIGHTMARE. I ALSO HAVE TOLD THE DEALERSHIP SEVERAL TIMES THAT THERE ARE TRANSMISSION PROBLEMS WITH MY VEHICLE. I INSISTED THEY DRIVE WITH ME AND ALTHOUGH THE TRANSMISSION ISSUES HAVE BEEN ACKNOWLEDGED, THE DEALERSHIP HAS BEEN BUSY REPAIRING THE ELECTRICAL DAMAGE OF THE BATTERY, THE HAVE NEVER TOUCHED MY TRANSMISSION. I STILL HAVE TRANSMISSION PROBLEMS. MY CAR HESITATES AND DOESN'T ACCELERATE CAUSING ME TO ALMOST WRECK SEVERAL TIMES. I ALSO HAVE HAD SEVERAL IGNITION PROBLEMS WITH MY VEHICLE....

THE BATTERY GO'S DEAD WHEN NOT STARTED FOR MORE THEN2 DAYS. *TR

FOR ABOUT A MONTH NOW EVERYTIME I GO TO PARK MY CAR MY SHIFTER GET STUCK AND I AM UNABLE TO PUT MY CAR IN PARK OR TAKE THE KEY OUT. I WENT TO THE DEALER SHIP AND I WAS TOLD I COULD SPEND $150 TO GET IT LOOKED AT & THEN SPEND HOW EVERY MUCH MONEY IT WOULD BE TO FIX IT. I DON'T HAVE THAT KIND OF MONEY FOR THAT AT THE MOMENT BUT NOW ITS TO THE POINT WHERE I CANT EVEN DRIVE MY CAR AT ALL BECAUSE THE SHIFTER ALWAYS GETS STUCK AND I CANT GET MY KEY OUT TO PARK OR PUT IT IN PARK DRIVE REVERSE ETC...... ! ! ! I HAVE SEEN THAT A COUPLE PEOPLE ARE HAVING THIS PROBLEM SO ITS NOT JUST MY CAR. BUT SINCE IT GETS SUCK I CAN BE DRIVING DOWN THE ROAD AND HIT THE SHIFTER BY...

A BAD SMELL LIKE ROTTEN EGGS, KEEPS COMING OUT OF THE AC/C VENTS AND THE ENGINE OF THE CAR. I CHANGED THE AIR FILTER AND EVERYTHING BUT NOTHING HAPPEN THE SMELL DOES NOT GO AWAY. *TR

TL* THE CONTACT OWNS A 2012 CHEVROLET SONIC. THE CONTACT STATED WHILE MAKING A TURN AT APPROXIMATELY 10 MPH, THE VEHICLE STALLED WITHOUT WARNING. THE FAILURE CAUSED THE CONTACT TO CRASH INTO A TELEPHONE POLE. THERE WERE NO INJURIES. A POLICE REPORT WAS NOT FILED. THE VEHICLE WAS NOT DESTROYED. THE VEHICLE WAS NOT TAKEN TO A DEALER. THE MANUFACTURER WAS NOT NOTIFIED OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 8,500.

ON OR AROUND DECEMBER, 2014, THE SHIFT COVER WOULD NOT ATTACH PERMANENTLY. ON OR AROUND MARCH 10, 2014, THE ELECTRICAL ACCESS PLUG DID NOT OPERATE. ON OR AROUND MARCH 6, 2014, MY MOTHER WAS DRIVING AROUND 45MPH, AND WE HIT AN ELK. NO AIRBAGS DEPLOYED. *TR

TL* THE CONTACT OWNS A 2012 CHEVROLET SONIC. THE CONTACT STATED THAT WHILE DRIVING AT VARIOUS SPEEDS, A CHIME SOUNDED WITH THE ILLUMINATION OF THE ENGINE OIL PRESSURE WARNING INDICATOR. THE FAILURE ALSO RECURRED UPON STARTING THE IGNITION. THE VEHICLE WAS TAKEN TO AN AUTHORIZED DEALER FOR DIAGNOSIS. THE TECHNICIAN INFORMED THAT THE OIL PRESSURE INDICATOR SWITCH WOULD NEED TO BE REPLACED. THE VEHICLE WAS CURRENTLY BEING REPAIRED. THE MANUFACTURER WAS NOTIFIED OF THE PROBLEM. THE APPROXIMATE FAILURE MILEAGE WAS 44,500.

AFTER MANUALLY TURNING OFF THE RADIO, TURNING OFF THE CAR, REMOVING THE KEY FROM THE IGNITION, EXITING THE CAR, LOCKING AND ARMING THE CAR'S ALARM, THE RADIO WILL TURN ITSELF BACK ON. IN SOME CASES IT HAS DONE THIS BEFORE WE HAVE EVEN WALKED 20 FEET FROM THE CAR, IN OTHER CASES IT HAPPENS UP TO 2 HOURS AFTER EXITING (AND LOCKING) THE CAR. IT HAPPENS MORE THAN 75% OF THE TIME. SHORTLY AFTER THE FIRST TIME WE OBSERVED THE SYMPTOM, THE CHECK ENGINE LIGHT CAME ON AND STAYED ON, BUT THE DEALERSHIP CLAIMED IT WAS NO LONGER ON AFTER I DROPPED THE CAR OFF (AND IT WAS DEFINITELY ON WHEN I EXITED THE STILL RUNNING CAR FOR THEM TO DRIVE INSIDE) AND THAT THERE ARE NO ERROR CODES IN THE HISTORY. THEY CLAIM THEY CANNOT REPRODUCE THE RADIO ISSUE. *TR

I PURCHASED MY SONIC IN APRIL OF THIS YEAR. I WAS INITIALLY WOWED BY THE AVG MPG I WAS ATTAINING BASED ON THE AVG REPORTED BY THE CAR'S COMPUTER. AFTER A FEW FILL UPS I REALIZED I WAS ADDING MORE GAS THAN THE MPG WOULD INDICATE. SINCE 6/21 I BEGAN RECORDING THE DIFFERENCE REPORTED BY THE COMPUTER AT EACH FILL UP & MY MANUAL CALCULATIONS. THE DIFFERENCE THRU 10/17 AVERAGED 5.6MPG (A LOW OF 2.3 & A HIGH OF 8.4 MPG) ALWAYS HIGHER. I TOOK IT TO THE DEALER & WAS TOLD THERE WAS NOTHING THEY COULD DO & THAT THE SVC MGR'S CADILLAC HAD THE SAME PROBLEM. IN FACT, I WAS TOLD BY HIM THAT THE COMPUTER'S FIGURE WAS THE "MPG THE CAR WAS GETTING AT THE MOMENT, NOT THE AVG SINCE LAST FILL UP. I'VE CALLED CHEVROLET, TOLD NUMEROUS PEOPLE ABOUT THE PROBLEM. I WAS PROMISED CALLBACKS &...
