2013 CHEVROLET SONIC Engine Problems

Vehicle enters into catalyst monitor too early. Monitor Fales indicating that the catalyst is below efficiency threshold. A vehicle is run for a significant amount of time before being allowed to enter the driving conditions for the catalyst monitor, monitor will pass. This indicates that there is a programming failure, not an actual component failure. Theory has been tested multiple times. Catalyst had also been tested by temperature sensor as well as by taking readings with a gas analyzer before and after the catalyst. Everything indicates the catalyst is well within operating parameters. Theories, test, and confirmations have been conducted by a certified technician and mechanical engineer.

Multiple parts in my engine have malfunctioned in the past year, the most recent being a tube bursting and getting coolant everywhere. Other problems have been with valves, temperature gauges and even the radiator. It’s like something new breaks every month. I have had every issue fixed and usually I don’t get a warning lamp until I’m broken down on the side of the road.

Boniface hiers Chevrolet dealer in Melbourne Florida said they did a full inspection before selling this vehicle. 2 days later after purchase the Radiator fan stop working even tho they put a new one, missing thermostat, code 3rd gear malfunction.

MY 2013 CHEVY SONIC DEVELOPED TICKING SOUND SHORTLY AFTER I BOUGHT IT AT 60000 MILES. THE TICKING GOT WORSE OVER TIME AND THEN CHECK ENGINE LIGHT CAME ON. I SCANNED THE CODES AND MULTIPLE FOUR CODES WERE FOUND. P0171, P0496, P1101, AND P2270. AFTER DOING SOME RESEARCH IT SEEMED TO BE THAT MOST CRUZE, SONIC, AND TRAX VEHICLES ALL HAD THE SAME ISSUES. I TOOK IT TO THE DEALER FOR DIAGNOSTICS AND WAS INFORMED THE VEHICLE NEEDED A NEW INTAKE MANIFOLD, PURGE VALVE, PCV HOSE, AND VALVE COVER. THEY CALLED THE DEALERSHIP TO SEE IF THERE WERE ANY RECALLS AND THE ONLY ONE WAS THE VALVE COVER BUT WOULD HAVE TO PAY FOR DIAGNOSTICS TO SEE IF THEY WOULD COVER IT OR NOT. THE BREATHER DIAPHRAGM IN THE VALVE COVER GOES BAD DUE TO A FAULT INTAKE MANIFOLD ON THESE VEHICLE MODELS. THERE IS A LITTLE ORANGE GASKET IN THE MANIFOLD THAT GOES BAD AND CAUSES THE DIAPHRAGM TO GO OUT RESULTING IN HAVING TO REPLACE THE ENTIRE SYSTEM. THE INTAKE MANIFOLD NOT ONLY CAUSES GHAT ISSUE BUT CAUSES THE CAR TO GET JUMPY AT STOPS AND STALLING OUT. HAVE ALMOST HAD A FEW PEOPLE REAR END ME DUE TO THIS. THE PURGE VALVE GOES OUT AS WELL AND WHEN AT THE FUEL PUMP THE CAR WILL HESITATE TO CRANK OR RUN AT VERY LOW IDLE SHUTTING OFF MULTIPLE TIMES BEFORE IT STARTS UP AND THEN RUNS ROUGH UNTIL A DECENT AMOUNT OF FUEL HAS RAN THROUGH THE ENGINE. THE CAR WOULD NOT GET ENOUGH FUEL WHEN AT STOPS OR ON HIGHWAYS AND WOULD ALSO JUST LOSE FUEL AND CUT THE ENGINE OFF. THOSE COMPONENTS HAVE SINCE BEEN REPLACED BY MYSELF AND NO MORE ISSUES. CHEVY WILL NOT RECALL THE PARTS THAT ARE CAUSING THE ISSUES AND THEREFORE THERE IS A SAFETY ISSUE WHEN OUT ON THE HIGHWAYS.

THE FUEL SYSTEM IS RUNNING WEAK, FOR A CAR WITH ONLY 30000 MILES, ONE OWNER AND FULL MAINTENANCE, THE ENGINE LIGHT CAME AND GO ALL THE TIME AND EVERYTHING WAS CHECKING

THE PCV PRESSURE REG VALVE FAILS AND CAUSES DAMAGE TO THE ENGINE. GM SENT A LETTER TO CUSTOMERS BUT ONLY COVERS THE WORK UP TO 120K MILES. MINE FAILED AT 125K MILES AND COST OVER $1000 TO FIX. GM IS REFUSING TO PAY FOR THE REPAIRS.10/15/2020

I PURCHASED MY VEHICLE 3 YEARS AGO PREOWNED FROM THE DEALER AND WITHIN THESE 3 YEARS I HAVE ALREADY HAD A CATALYTIC CONVERTER RECALL, THE ISSUE RECENTLY IS MY AC SYSTEM IN MY CAR IS OUT AND AS A DID RESEARCH ON THE SPECIFIC YEAR THERE'S PEOPLE WHO HAVE ALREADY REPLACED THE AC SYSTEM UP TO 5 TIMES FOR 2013 SONICS. THIS IS A MANUFACTURING ISSUE THAT NEEDS TO BE FIXED ON CHEVROLET'S BEHALF.

LEAKING WATER PUMP

MY CAR HAS LEAKED OUT ITS ENTIRE COOLANT TWICE NOW WITHIN A SIX MONTH PERIOD. THIS TIME IT HAS LEAKED FLUID ONTO THE COMPUTER CAUSING FURTHER ISSUES THAN AFTER THE FIRST FIX. THE LACK OF A TEMPERATURE GAUGE TO PREVENT THE CAR FROM OVERHEATING IS A HUGE ISSUE. I CONSTANTLY MAKE SURE THERE IS COOLANT BEFORE DRIVING THE VEHICLE AND ALL IN THE SAME DAY IT HAS EMPTIED WITHOUT MY KNOWLEDGE CAUSING A CHECK ENGINE LIGHT AND BREAKDOWN INSTANTLY. IT HAS HAPPENED TWICE NOW WITH MY TODDLER IN THE VEHICLE, THIS SHOULD BE A RECALL BECAUSE FORTUNATELY IT HAS HAPPENED WHILE ON STREET ROADS, WHERE I COULD IMMEDIATELY AND SAFELY MOVE INTO A PARKING LOT, AND NOT THE HIGHWAY BUT THIS SITUATION PUTS MY CHILD'S HEALTH AT RISK AND THAT I AM NOT OKAY WITH.

HAVING FUEL ISSUES BIG DIFFERENCE WEEKS APART FUEL ISSUES.THEN OVER HEATING, NEXT UNABLE TO HOLD COOLANT, CAR WAS RETURNED TO DEALER FOR REPAIR. STILL UNABLE TO KEEP COOLANT FROM LEAKING, WHILE DRIVING ON INTERSTATE I 95 OUT OF NO WHERE I LOOSE THE ABILITY OF SPEED THEN SHUTTERING RUNNING HOT AGAIN BLEW HEAD GASKET LOST POWER HARD TO GAIN CONTROL AND WAS ALMOST HIT 2 TIMES BY CAR BEHIND AND ON SIDE.CAR HAD TO BE PUSHED TO SHOULDER AND PICKED UP WITH WRECKER SERVICE. MECHANIC HAD TO COME TO CAR BC IT WOULDN'T STSRT. HE SAID THE GASKET IS GONE. CAR WILL NOT DO ANYTHING NOW. WILL GET RECEIPTS FROM DEALER SERVICING, WRECKER, AUTO ZONE MULT COOLANT PURCHASES, MECHANIC

I WAS DRIVING TO WORK AND WAS COMING UP TO AN INTERSECTION I HAD TO TURN AT. I PUSHED THE BREAK PEDAL, BUT IT WAS REALLY STIFF AND DIDN'T DO MUCH. MY CAR SLID ACROSS THE ROAD INTO A WOODEN ELECTRIC POLE BECAUSE IT WOULD NOT STOP. MY CAR IS TOTALED AND NOW I HAVE TO FIGURE OUT SOME WAY TO GET A DIFFERENT VEHICLE.

CODE P0171 AND P0420. I HAVE REPLACED EVERYTHING IN THE CAR THAT THESE CODES STATE. NEW THERMOSTAT, CATALYTIC CONVERTER, BOTH 02 SENSORS, EXHAUST HOSE. FIXES FOR A FEW DAYS TO A WEEK AND THE SAME CODES KEEP COMING BACK. NOW THE BUTTON ON MY GEAR SHIFT STICKS KEEPING THE GEAR SHIFT FROM LOCKING INTO PLACE. THIS STOPS ME FROM BEING ABLE TO TURN MY CAR COMPLETELY OFF AND REMOVING KEY FROM IGNITION.

THE SONIC NOW RUNS VERY SPOTTY, POOR ACCELERATION, AND SLOW BUMPY IDLE. PRIOR BALL JOINT WAS REPLACED AND THE CV AXIL , ENTIRE ENGINE REPLACED. BELIEVE IT OR NOT, WATER PUMP REPLACED. THESE REPAIRS, WITH RECEIPTS, CONSTITUTE A LEMON LAW BREACH. I SHOULD BE ENTITLED TO A NEW CAR OR COMPENSATED. YES, THE SUSPENSION ISSUE DID HAPPEN WHILE I WAS DRIVING, AS WELL AS THE ENGINE. WILL UPLOAD DOCUMENTS SOON.OH, ONE LAST THING, VERY DIFFICULT REMOVING KEY FROM IGNITION, BEEN GOING ON 4 MONTHS.

Mileage: 90,000

WHEN THE CAR IS FIRST STARTED AND TURNED OFF, THE HORN GOES OFF EACH TIME. IF PARKED BUT STILL RUNNING, THE HORN GOES OFF EVERY 2-3 MINUTES. WHEN LOCKING THE CAR, IT DOESN'T MAKE ANY NOISE INDICATING IT HAS BEEN LOCKED. WHEN PHONE IS PLUGGED IN, THE MUSIC DOESN'T ALWAYS WORK PROPERLY. THERE IS A PIECE TO ONE OF THE HOSES THAT BROKE AND IS NOW MAKING CAR RUN LEAN. WHEN IDLING (AT A RED LIGHT OR STOP SIGN) THE ENGINE SHAKES VIGOROUSLY AND IS HARDER TO GET BACK SPEED. WHEN CAR IS RUNNING AND THE HOOD IS OPEN, THERE IS A HISSING SOUND.

Mileage: 79,000

TAKATA RECALL - THE ENGINE HAS BEEN MISFIRING THIS HAS ALSO HAPPEN TO SOMEONE ELSE I KNOW WHO HAS HAD THE SAME VEHICLE. THIS IS VERY UNSAFE AND THEY DON'T HAVE IT AS A RECALL YET BUT ALL OF THE DEALERSHIP ARE AWARE OF IT. THE VEHICLE JERKS WHEN YOUR DRIVING OR WHEN ITS PARKED. THIS IS NOT THE ALTERNATOR OR ANYTHING ELSE I HAD THAT REPLACED AND NOTHING WAS WRONG WITH IT AND THE SAME ISSUE IS STILL OCCURRING. IT A BAD PART THEY PUT IN THE ENGINE AND IT NEEEDS TO BE RECALLED. IT IS UNFAIR AND NOT SAFE FOR CUSTOMERS WITH THIS ISSUE. THE VEHICLE JERKS AND WHEN IS DOES IT IT FEELS LIKE IT HESITATES TO DRIVE WHILE IN DRIVE MODE. THIS HAS BEEN HAPPENING FOR A COUPLE OF MONTHS IT HAS JUST GOTTEN WORSE AND I AM TRULY SCARED.

Mileage: 94,000

I HAVE FOUND ONE NEW LEAK AND ONE LEAK THAT HAS BEEN THERE FOR AT LEAST A YEAR. THE NEW LEAK IS THE RADIATOR. IT IS LEAKING AT THE TOP ON THE DRIVER SIDE RIGHT WHERE THE PLASTIC AND ALUMINUM MEET. THE OTHER LEAK IS THE PLASTIC THERMOSTAT HOUSING. CURRENT MILES: 69,500

Mileage: 69,500

TL* THE CONTACT OWNS A 2013 CHEVROLET SONIC. WHILE OPERATING THE VEHICLE, A BURNING ODOR WAS PRESENT. UPON INSPECTION, IT WAS DISCOVERED THAT FLUID/WATER WAS LEAKING FROM THE ENGINE COMPARTMENT. THE VEHICLE WAS TAKEN TO 5 STAR CHEVROLET (495 WATSON BLVD, WARNER ROBIN, GA) WHERE IT WAS DIAGNOSED THAT THE WATER PUMP WAS FAULTY. THE CONTACT INDICATED THAT THE WATER PUMP WAS PREVIOUSLY REPLACED, BUT THE FAILURE RECURRED ONE YEAR LATER. THERE WERE NO WARNING INDICATORS ILLUMINATED WHEN THE ENGINE OVERHEATED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOTIFIED. THE FAILURE MILEAGE WAS 85,000.

Mileage: 85,000

I HAVE EXPERIENCED FOUR COOLING SYSTEM (RADIATOR, WATER PUMP, ENGINE BLOCK COOLANT INTAKE, COOLANT EXPANSION TANK, ENGINE/TURBO COOLANT PIPING) RELATED PROBLEMS WITH THIS VEHICLE AMOUNTING TO OVER THREE THOUSAND DOLLARS IN REPAIR COSTS. FOUR MAJOR REPAIR EXPENSES ON THE SAME SYSTEM IS QUESTIONABLE IN MY OPINION, THE TWO MOST MAJOR OCCURRING WITHIN THE SAME MONTH. THESE ALL WERE NOTED DURING NORMAL OPERATION OF THE VEHICLE.

Mileage: 131,143

AIR INTAKE SYSTEM. NOT LONG AFTER WE BOUGHT THE CAR THE CHECK ENGINE LIGHT CAME ON READING A CODE PH171. WE WERE TOLD IT WAS A KNOCK SENSOR WHICH WE REPLACED AND IT DIDN'T FIX THE PROBLEM, AFTER WE WERE TOLD IT WAS THE AIR INTAKE HOSE, CHECKED IT AND IT LOOKS LIKE IT'S A NEW HOSE NO ISSUES WITH IT. NOW WE ARE TRYING EVERYTHING WE CAN TO FIGURE OUT THE PROBLEM. WE CHECK ONLINE FORUMS AND FOUND OUT THAT THIS IS A HUGE PROBLEM WITH THIS CAR AND ALMOST NO ONE KNOWS EXACTLY WHAT IT IS TO FIX IT. WHEN THE CAR IS DRIVING IT SEEMS FINE BUT AS SOON AS YOU STOP AND IT IDLES IT SEEMS LIKE IT WANTS TO DIE AND ALMOST HAS A FEW TIMES. WAS JUST CURIOUS IF THIS IS SUCH A HUGE PROBLEM THAT SO MANY PEOPLE ARE HAVING WHY THERE HAS NOT BEEN A RECALL?

VEHICLE STALLS AND TURNS OFF ON ITS OWN WHILE DRIVING. NO WARNING. NO CODES APPEAR ON DASH. AFTER APPRX 5-10 MINUTES OF THE CAR BEING DEAD (NOT ABLE TO START) IT SEEMS TO "REBOOT" AND START BACK UP AGAIN WITHOUT A JUMP TO THE BATTERY. THE CAR HAS STALLED ON BOTH THE FREEWAY (1ST TIME) AND CITY STREETS. I'VE TAKEN THE CAR TO TWO DIFFERENT DEALERS AND BOTH ARE UNABLE TO DUPLICATE THE PROBLEM AFTER HAVING THE CAR FOR 3 WEEKS COMBINED. A CLAIM HAS BEEN SUBMITTED TO GM BUT WITH NO RESOLUTION. THE CAR JUST TURNED OFF ON ME THIS MORNING WHILE DRIVING MY DAUGHTER TO SCHOOL LOCATED APPRX 1 MILE AWAY FROM MY HOME. BOTH OF MY DAUGHTERS HAVE WITNESSED THE PROBLEMS NOW 3-4X.

Mileage: 60,000

THINGS STARTED AFTER MY VEHICLE WAS REPAIRED AFTER A CAR HIT ME AND TOOK OFF. I NOTICED THE CHECK ENGINE LIGHT CAME AND STAYED ON, AT CERTAIN TIMES THE CAR EITHER WHILE DRIVING OR WHILE STOPPED THE CAR WILL EITHER SHAKE FOR 2-3 MINUTES OR ALSO WHILE STATIONARY THE TRACTION SYSTEM LIGHT WILL COME ON THEN TURN OFF. I'VE ALSO EXPERIENCED ISSUES WITH SLOW OR NOT AS RESPONSIVE ACCELERATION OR UNPROMPTED RPG GAUGE REVVING AND SOMETIMES THATS COUPLED WITH THE SHAKING TO THE POINT THAT MY HAS SHUT OFF WHILE DRIVING DOWN A CITY STREET. I WAS NEVER AWARE OF ANY RECALLS SO IM NOT SURE IF IT HAS ANYTHING TO DO WITH A POSSIBLE RECALL THAT HASNT BEEN DIAGNOSED BUT THERES GREAT CAUSE FOR CONCERN. - SN: I WASNT ABLE TO CHOOSE EVERY AFFECTED PART.

Mileage: 16,000

THE CAR HAS BEEN HAVING INTERMITTENT REDUCED ENGINE POWER SINCE SEPTEMBER 2016. THE CAR WAS TAKEN TO THE DEALER, THE CHECK ENGINE LIGHT NEVER ILLUMINATED AND NO PROBLEM WAS DIAGNOSED. DURING A RECENT TRIP THE CAR BEGAN TO HAVE REDUCED ENGINE POWER AND SURGING. THE CHECK ENGINE LIGHT ILLUMINATED. TROUBLE CODE P0171. THE CAR WAS TAKEN TO THE DEALER WHO SET AN APPOINTMENT. CHECK ENGINE LIGHT TURNED OFF AFTER A COUPLE OF DAYS. ON THE WAY TO THE DEALER THE CAR ALMOST DIED AT A STOP LIGHT. THE PROBLEM WAS DIAGNOSED AS EVAP PURGE CONTROL SOLENOID.

Mileage: 88,000

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.

Mileage: 87,800

ACCELERATION IS BAD, AND INCONSISTEN. ALSO, WHEN SHIFTING GEARS THE SHIFTER BUTTON GETS STUCK EVERYTIME NEVER FAILS. THAT'S A REAL SAFETY ISSUE CONSIDERING I ACCIDENTLY BUMP IT, AND THE CAR WENT INTO MANUAL, WHILE DRIVING. I BARELY TOUCHED IT AND IT MOVED. THIS IS THE LAST GM CAR THAT I WILL EVER BUY ALWAYS SOMETHING WITH THEIR CARS. THE ACCELERATION FOR THIS CAR ON THE INTERSTATE IS BAD PEOPLE GO AROUND ME BECAUSE IT TAKES SO LONG TO ACCELERATE, IT ALSO HESITATES WHEN ACCELERATING. I'VE ONLY HAD THIS CAR FOR ABOUT A MONTH.

Mileage: 82,500

TL* THE CONTACT OWNS A 2013 CHEVROLET SONIC. WHILE DRIVING UNKNOWN SPEEDS, THE CONTACT SMELLED BURNING OIL AND SMOKE.

KEY STICKS IN THE IGNITION, UNABLE TO REMOVE WHEN IN PARK POSITION. I WORK A DANGEROUS JOB IN BAD AREAS AND CANNOT DEPEND ON THE KEY BEING RELEASED FROM THE SWITCH AFTER PARKING. WHATCH PUTS ME IN A AWKWARD SITUATION IN REGARDS TO SAFETY.

WHILE DRIVING MY CAR FOR THE PAST YEAR NOW I HAVE NOTICED MY RPM GAUGE STICKING AND REVVING ON ITS OWN. IT IS STARTING TO HAPPEN MORE CONSISTENTLY. WHEN I'M DRIVING DOWNHILL THE RPM GAUGE WILL REV HIGH AND STAY STUCK HIGH. THEN WHEN I PUT THE CAR IN PARK IT WILL REV HIGH ON ITS OWN AND STAY STUCK AND EVENTUALLY COME BACK DOWN. SOMETHING NEW I HAVE STARTED TO EXPERIENCE IS WHEN I'M AT A COMPLETE STOP THE RPM GAUGE WILL START REVVING UP AND DOWN ON IT'S OWN WHILE MY CAR LIGHTS BRIGHTEN AND DIM AND MY WARNING LIGHT COMES ON THAT I'M SLIDING WHICH IS IMPOSSIBLE SINCE I'M AT A COMPLETE STOP. I HAVE ALSO NOTICED THE TRANSMISSION HAS STARTED TO FEEL JERKY LATELY WITH EVERYTHING ELSE. I JUST PURCHASED THIS VEHICLE ALMOST 2 YEARS AGO AND I ONLY HAVE 58,000 MILES ON IT.

CAR SHAKES VERY BAD WHEN DRIVING AND APPROACHING A STOP.

GM PART NUMBER 95027313 OUTLET DUCT CONNECTING THE AIR BOX TO THE THROTTLE BODY HAS SHREDDED IN 30,000 MILES OF USE. THIS PROBLEM CAUSES THE ENGINE TO RUN LEAN (ODB2 ERROR CODE P0171) RESULTING IN SIGNIFICANTLY REDUCED FUEL ECONOMY, POOR ACCELERATION, ROUGH IDLE, AND POTENTIAL FAILURES TO A NUMBER OF COSTLY SENSORS AND COMPONENTS, AS WELL AS ALLOWING DIRTY, UN-FILTERED DIRECTLY INTO THE ENGINE. A QUICK GOOGLE SEARCH REVEALS 26,000 SEARCH RESULTS INCLUDING FORUMS AND MESSAGE BOARDS WHERE COUNTLESS SONIC OWNERS REPORT THE SAME ISSUE. THIS IS A WIDESPREAD PRODUCT DEFECT AND GM NEEDS TO PROVIDE A REPAIR SOLUTION FOR OWNERS OF THIS MODEL VEHICLE. THE PART HAD DETERIORATED TO THE POINT, WHERE THE CHECK ENGINE LIGHT ILLUMINATED. THE CONSUMER NOTICED THE FUEL ECONOMY OF THE VEHICLE DROPPING STEADILY FROM THE ADVERTISED 29/CITY/40 HIGHWAY TO AN AVERAGE OF ABOUT 25 MPG HIGHWAY.

I PURCHASED MY CAR FROM A DEALER, WHO SET ME UP FOR AN UPSIDE LOAN. PUTTING ME INTO ANOTHER CHEVY WITH NOW 2 CAR LOANS TO PAY OFF. THE CAR HAS STALLED ON ME AT DIFFERENT TIMES WHILE OWNING IT. THERE HAVE BEEN ISSUES SINCE SHORTLY AFTER PURCHASING IT WITH ACCELERATION. IT JOLTS AND JUMPS WHEN TRYING TO ACCELERATE. THE CHECK ENGINE LIGHT IS ONE, SOMETIMES IT GOES OFF, THEN WILL COME BACK ON. I HAVE NOT TAKEN IT TO THE SHOP YET ASSUMING IT WOULD BE A HUGE EXPENSE FOR THEM TO FIX AND FIND IT. TOOK IT TO A PRIVATE GARAGE AND THEY COULD NOT FIND THE ISSUE EITHER. THIS CAR IS CRAP, I OWE TWICE AS MUCH AS ITS WORTH AND I DO NOT KNOW WHAT TO DO WITH IT. I DRIVE AN HOUR TO WORK EVERY DAY ON THE HIGHWAY AND I AM TERRIFIED I AM GOING TO CRASH EVERY SINGLE DAY. IT HAPPENS ON THE HIGHWAY, ON THE STREET. IN THE MORNING WHEN IT START UP IT JOLTS AND SPUTTERS. IF YOU USE THE HEAT, IT SMELLS LIKE ITS BURNING AND THERE IS A HIGH SQUEALING NOISE COMING FROM THE PASSENGER SIDE.

MY CHEVY SONIC HAS HAD A CLICKING NOISE SINCE I PURCHASED IT. IT GOES DEAD WHEN GAS CAP IS REMOVED AND WILL NOT CRANK BACK. I HAD IT WORKED ON AT A DEALERSHIP $306 LATER IT IS STILL DOING THE EXACT SAME THINGS. I PURCHASED VEHICLE WITH 21 MILES ON IT. I AM ON THE ROAD FOR MY JOB. THIS VEHICLE HAS BEEN A HEADACHE SINCE PURCHASE. I CANNOT AFFORD ANOTHER PAYMENT. SURE CANT AFFORD THE BILL FROM THE SHOP WHEN IT DOESN'T FIX ANY OF THE PROBLEMS. THE VEHICLE HAS HAD TO BE JUMPED OFF TO START. I PURCHASED NEW BATTERY EVEN WHEN AUTO PARTS STORE TESTED OLD BATTERY AND STATED IT WAS GOOD AND ALTERNATOR WAS CHARGING. I AM FURIOUS. WHAT IS A HONEST PERSON TO DO?????WHEN DEALERSHIP DOESN'T HOLD UP TO CORRECTING THE PROBLEM. NOTHING TO THEM IT RUINS YOUR CREDIT, NOT THEIR NAME. I HAVE HAD TO BE TOWED DUE TO VEHICLE NOT CRANKING EVEN WHEN BEING JUMPED OFF. HELP!!! DEALERSHIP/GM SHOULD BE HONEST AND FIX THE PROBLEMS. APPARENTLY THEY DON'T VALUE REPEAT CUSTOMERS!!!
