2014 Chevrolet Sonic Problems

Electric My coolant And leaking issues My car door look when keys are inside ignition

Vehicle keeps throwing error code P2138 there is a current known issue that GM is aware of see notice 070604019F. Water gets in the electrical connections of sensors and is an issue as it causes check engine light and can decrease power of the acceleration of the vehicle which is a safety hazard. My vehicle has been with the dealer now for a third time for same issue. They’ve had it for 3 weeks and 2 days total. Still an issue.

"off" remains illuminated on my passenger airbag light whether or not someone is sitting in the passenger seat. It's actually somewhat rare to see "on" illuminated. There was a recall on this model for airbag issues but my vehicle specifically was not recalled. My vehicle was recalled for catalytic converter but I'm still getting codes. Most of the problems the Sonic has been recalled for, my vehicle has symptoms of but I get cannot afford to pay repair cost up front and I cannot find a mechanic who would be willing to take the steps to report my vehicle should've been apart of the recall.

Passenger airbag not active even though an average sized (160 pound) adult is sitting there.This is very very dangerous.Apparently a pressure sensitive monitor in the passenger seat is not working correctly.I have read many many complaints about this on the Chevrolet Sonic on this website.This started out as a sporadic problem,but now is constant.

My auto started out with a Check Engine Light. I noticed the engine smelled of overheated radiator and coolant smell. Parts were replaced for fix (Hose)...but check engine light continued as well as the overheated coolant smell. The auto was placed for checking on machine for codes for check engine light, but none of codes made sense to Mechanic. Told to bring back for further testing/looks. Brought back several times. No idea what was wrong but last time I was told I needed to leave for extended testing and test driving as gears were not shifting in D struggled engine for me, no acceleration and RPMs raced at times. (Dangerous and unpredictable on highway and in town). Now I turned in for testing to Chev Mechanic, and now am facing a part that was replaced in control of electrical (over $500) and after they repaired that and tested I am told that I have a TOTAL TRANSMISSION REPAIR over $5200 - for a 2014 auto!!! It was in with dealership mechanics a total of 6-7 times. I was informed the electrical controls were confusing the engine reactions. Auto a dealers for $5200 + $500 repairs now 20230702 and problems seen & looked at since March for smell of overheating radiator, fix if hose (wonder if really needed), continued check engine light, refill of radiator fluid, codes checked and did not give correct evaluation. Eventually the transmission needs replaced out, at time that there is RPM revs, no acceleration while driving and gears heard to struggle in engine. Mileage now over 97000. Estimate on mileage, i do not have all documentation before me. Extended Powertrain warranty from dealership started at year 2015!!! Anything older not allowed, so I am told I have to pay the entire bill.

Traction contorl light and check engine light comes on and its throwing my car into limp mode. we have changed out the throttle body and the pedal sensor and still having the same problem.

Power steering light came on while Driving and lost power steering assist control. Almost crashed while turning down the street.

The contact owns a 2014 Chevrolet Sonic. The contact stated that while driving at an undisclosed speed, the steering wheel seized and the vehicle then stalled. The contact pulled over at a gas station and parked the vehicle. The vehicle was not diagnosed nor repaired by an independent mechanic or dealer. The manufacturer was not made aware of the failure. The failure mileage was approximately 67,000.

Since January I’ve consistently had issues with my 2014 Chevy Sonic Hatchback, in particular, Codes 84, P2138, check engine light and traction control lights. (my job has us all working from home since March of 2020, so I only do local shopping, no long distance). Due to the codes mentioned above, my car was “repaired” at dealership on January 4, 2012. In the end of March I was constantly getting the same codes over a period of two days. I called GM (1 800 462 8782) on March 29, spoke with a woman by the name of Michelle and I explained what has been happening with the vehicle codes, along with other issues over the past year. She opened a case file # 9-6627321866 and she called the dealership to discuss my issue. I was told to drop the car off and it will be repair at no cost to me. The car was brought to dealership on April 7, 2021 and when the diagnostic was preformed, it showed no codes in the history. They did no repair at that time and gave me back the car. While running local errand on April 17, all the same codes appeared and once again I had reduced engine power. I was near the dealership and dropped off the vehicle, even though the service department was closed at that time. Once again, a new pedal and sensor was installed. I told them to please keep the vehicle for a few days, test drive it once in a while to ensure it is truly repaired. They test drove it several times during the 4 days they had it and since there were no issues, I picked the vehicle up on April 22, 2021.On June 5, while driving to a store a nearby store, I was stopped at a light to make a left turn and all the codes suddenly came on. I had very little acceleration making the left turn. The vehicle approaching me which was a block and a half away was now very closely approaching me and luckily realized I had an issue and stopped. I immediately headed back home. AutoZone ran a diagnostic and it's the same issue.

THISNVEHICLE WAS PURCHASE ON THE YEAR 2016 OF APRIL. SO HAPPY AT FIRST BUT IN A COUPLE OF WEEKS HAVE PROBLEM WITH LIGHTS AND ONE OF TTHE COVER OF THE FRONT MIRRORS ARE MISSING . CALLED AND WENT BACK TO THE DEALER (TOYOTA OF NORTH HOLLYWOOD ) AND SAID BRING IT TO THE CHEVY BRANCH WHERE THEY CANNCHECK AND FIX IT . IT WAS STRESSING AND DEPRESSING CAUSE EVRYWEEK PASSED YOU'LL EXPERIENCED ANOTHER PROBLEM SUCH AS AIRDCONDITION AND HEATER NOT WORKING . I'VE BEEN BACK AND FORTH TO CHEVY IN VAN NUYS , CALIFORNIA BUT THEY ARE SAYING THAT THERE'S NO WARRANTY ON THE VEHICLE . I TRIED TO RETURN THE VEHICLE TO THAT DEALER BUT THEY SAID THAT MY CREDIT SCORE STILL LOW OF COURSE IT WILL SHOW THAT CAUSE I JUST BOUGHT IT AND MY CREDIT HASN'T BEEN SMESTABLISH YET , WHEN I BOUGHT IT THEY ASKED A LARGE AMOUNT $3500 OF DOWN PAYMENT DUE TO HAVING LOW SCORE. IT DOESN'T MAKE SENSE CAUSE I WILL USE A VEHICLE THAT HAS ELECTRICAL DISFUNCTIONAL. I HAVEN'T EVEN USE THE HEATER AND THE AIRCON ON THIS CAR EVER SINCE I BOUGHT IT CAUSE IT'S NOT WORKING . YOU CAN ASK THE DEALER HOW MANY TIMES I WENT THERE AND TRIED TO BEG TO GIVE ME A DIFFERENT CAR BUT NO LUCK INSTEAD I FOUND OUT THE SALES PERSON SOLD THE CAR TO ME WASN'T WORKING THERE ANYMORE . AND I WALKED OUT WITHOUT ANY HELP FROM THEM . YOU CAN EVEN ASK CHEVY IN VAN NUYS HOW MANY TIME I'VE BEEN THERE TO ASK HELP CAUSE THE DEALER ALWAYS POINTING ME BACK TO THEM . IT'S HARD TO USE A FINANCE CAR PAYING $396 SOMETHING A MONTH AND THE CAR IS NOT FUNCTIONING RIGHT . THEY HAVE ADDED A GAP INSURANCE ON MY CONTRACT AND EVEN THAT COMPANY WASN'T HELPING ME AT ALL . SO I END UP USING THIS CAR WITHOUT ACCESS ON AIRCONDITION AND HEATER . SUFFER 4 YEARS WITHOUT THESE BENEFITS . I COULDN'T AFFORD FIXING THAT EVER SINCE CAUSE IT'S TOO EXPENSIVE . YOU CAN SEE THAT I HAVEN'T PUT A LOT OF MILEAGE ON THIS CAR CAUSE I DON'T REALLY USE IT THAT MUCH. STILL PAYING THIS .

THE ROAD I WAS DRIVING ON IS 55 MPH ON BEAR IN. AS I BEGAN TO BREAK NOTHING HAPPENED. A 90 CORNER WAS IN FRONT OF ME. 55TH AVE. I PUSHED AS HARD AS I COULD ON THE BREAKS. IT WAS SMOOTH.. TRACTION CONTROL WAS ON. NO BREAKING UNIT WENT INTO AFFECT. IT WAS SMOOTH ALL THE WAY INTO A TREE HEAD ON. ZERO SKID MARKS! I WAS CONSCIOUS THE ENTIRE TIME CLOSED ON EYES RIGHT BEFORE IMPACT. AIR BAGS DID WORK. THE ENGINE STARTED ON FIRE 3X. THEY HAD TO USE THE JAWS OF LIFE TO REMOVE THE VEHICLE FROM THE TREE. I PUSHED SO HARD ON THE BREAK THAT IT BROKE MY ANKLE, SPLIT MY KNEE OPEN AND SPRAINED MY KNEE. I WAS TAKEN TO THE HOSPITAL. MILEAGE ON THE VEHICLE WAS ABOUT 56K. THIS SHOULD HAVE KILLED ME. THE BREAKS HAD WORKED FINE BEFORE THIS.. NO SQUEALING, SHAKING ETC. IN GOOD WORKING ORDER. CONDITIONS WERE DARK, DRY ROADS, NO WIND. I DO HAVE REPORTS BUT CAN NOT SCAN THEM. I LOADED 5 IMAGES! PLEASE LOOK INTO THIS MATTER IMMEDIATELY. LIVES ARE AT STAKE.

BRAKE PEDAL FEELS TOO SOFT AND CAUSES THE CAR TO HAVE PROBLEMS WITH MAKING SMOOTH STOPS. I NOTICED THIS CHANGE IN OCTOBER 2016. THIS PROBLEM IS PARTICULARLY DANGEROUS WHEN YOU ARE REQUIRED TO MAKE SUDDEN STOPS AT INTERSECTIONS OR IN HEAVY TRAFFIC. THIS HAPPENS WHEN DRIVING ON CITY STREETS, NEIGHBORHOOD STREETS AND ON HIGHWAYS. I AM CONCERNED THAT THIS COULD RESULT IN ANOTHER VEHICLE FROM STRIKING MINE IN THE REAR OR A CHILD BEING HURT OR KILLED WHEN I DRIVE THROUGH MY NEIGHBORHOOD STREETS. IT IS VERY UNPREDICTABLE. I TOOK IT TO MY CHEVROLET DEALER AND THEY SAID THEY WERE UNABLE TO DUPLICATE THE PROBLEM AT THAT TIME. I AM INCLUDING AN IMAGE OF THE DEALER'S SERVICE REPORT FROM 11/09/2016. THE PROBLEM STILL CONTINUES TO THIS DATE, 8/8/17. SINCE THE PROBLEM IS ONGOING, I CANNOT REPORT AN ACTUAL DATE, MILEAGE, OR DRIVING SPEED.

TEMP 45-50 DEGREES, DRIVING IN MODERATE RAIN FOR 20-25 MINUTES, CRUISE CONTROL ON. ACTIVATE HIGH BEAMS, CAR SHIFTS TO 1ST GEAR AT 65 MPH, RPMS JUMP ABOVE 6000, TURN OFF HIGH BEAMS RETURNS TO NORMAL OPERATION. REPEATED 2 MORE TIMES IN NEXT 4 MILES, EVEN AT 25 MPH. WHEN END OF TRIP, SHUT OFF CAR AND COMPLETELY DEAD, NO LIGHTS, NO CRANKING. FOLLOWING MORNING (TODAY) CAR STARTS NORMALLY. WILL REPORT ANY FURTHER FROM MY COMMUTE TODAY, IF WARRANTED

CANNOT TAKE THE KEY OUT WHEN CAR IS IN PARK.

THE BUTTON ON MY GEAR SHIFTER WAS STUCK FOR A FEW MONTHS AND THEN IT BROKE RESULTING IN ME CRASHING INTO A PARKED CAR BECAUSE I LOST CONTROL.

THE GEAR BUTTON BROKE AND STICKS/IS STUCK

The contact owns a 2014 Chevrolet Sonic. The contact stated that while driving at various speeds, the A/C failed to function as intended. The contact stated that there was hot air blowing from the vents at all time. In addition, the contact stated there was an abnormal sound coming from the engine, with an abnormal fuel burning odor on the interior and exterior of the vehicle. No warning lights were illuminated. The vehicle was taken to an independent mechanic; however, no cause for the failure was found. The vehicle was not repaired. The manufacturer was not notified of the failure. The contact related the failure to NHTSA Campaign Number: 14V417000 (EQUIPMENT). The failure mileage was unknown. The VIN was not available.

DEALER SOLD ME CAR WITH BALD TIRES LESS THAN 2/32. DEALER SOLD CAR WITH FILTHY RUSTY AND LOOSE PARTS ON MANIFOLD. VALVES. STRUTS. AND TRANS MOUNT. SUSPENSION PIECES WERE BROKEN AND OLD. THE THERMOSTAT WAS PUT IN WRONG AND CAUSED DIVID IN MANIFOLD. BATTERY AND ELECTRICAL SYSTEM ALSO HAD ISSUES. ALL ISSUES WERE FROM MILE 1 TO 200 OF OWNING CAR.

I HAVE A CONCERN THAT NEEDS TO BE ADDRESS. MY PASSENGER SEAT LIGHT COMES ON AND GOES OFF ON ITS OWN. I HAD MY CAR LOOKED SOMETIME AGO AT A DEALERSHIP ALONG WITH PROBLEMS WITH THE WINDOW ON THE FRONT PASSENGER SIDE. NOW THE BACK PASSENGER RIGHT SIDE WINDOW JUST WENT OUT WITHOUT A WARNING. I AM NOW STUCK WITH A WINDOW. THAT I CANNOT ROLL UP OR EVEN MANUALLY. I AM STARTING TO BELIEVE MY CAR I PURCHASED BRAND NEW WITH 9 MILES ON IT. HAVE ELECTRICAL ISSUE, THAT HAVE NOT BEEN ADDRESS. THIS CAR IS NOT OLD ENOUGH TO HAVE THIS TYPES OF PROBLEMS. I AM JUST BAFFLED OF HOWEVER EVERYTHING IS OUT OF POCKET. LAST YEAR I SPENT OVER $200 GETTING MY CAR FIXED SOMETHING ABOUT FUEL LINE OR SOMETHING WAS CLOGGED. I AM LIKE HOW IS THAT POSSIBLE WHEN I TAKE MY CAR IN FOR OIL CHANGES ON THE REGULAR. THIS IS NOT A 7 YEAR OLD OR PLUS CAR. I SHOULDN'T BE HAVING THESE PROBLEMS ALREADY IN MY 1ST YEAR - 4TH YEAR. I HAD TO CHANGE BATTERIES TWICES AS WELL. CAN YOU PLEASE ASSIST. MULTIPLE CAR PROBLEMS FOR A 2014 I BROUGHT NEW ARE CAUSING ME A HARDSHIP.

I UNDERSTAND THAT NHTSA HAS MANDATED FORWARD-LEANING HEAD RESTRAINTS ON ALL LATE-MODEL VEHICLES. THE HEAD RESTRAINT IN MY 2014 SONIC IS TERRIBLE; IT SHOVES MY HEAD FORWARD, FORCING ME TO EITHER STARE AT THE INSTRUMENT CLUSTER OR RAISE MY EYES IN A KUBRICK STARE TO SEE THE ROAD. IT WASN'T IMMEDIATELY APPARENT DURING THE TEST DRIVE, BUT AFTER 200+ MILES OF DRIVING IN LESS THAN A WEEK, MY NECK IS STIFF AND SHOULDERS FEEL LIKE ROCKS. ALL THIS PAIN AGAINST THE STATISTICALLY UNLIKELY OCCURRENCE OF BEING REAR-ENDED (TWICE IN 30 YEARS OF DRIVING)? FAIL. ABSOLUTE, 100%, TOTAL FAIL. MY 2012 CRUZE HAD STRAIGHT HEAD RESTRAINTS THAT DIDN'T CAUSE ME PAIN AND WERE STILL AVAILABLE WHEN I NEEDED TO BRACE (SEEING SOMEONE RACING UP BEHIND ME, FOR INSTANCE). PLEASE, FOR THE LOVE OF G-D, RECONSIDER THIS IDIOTIC AND OVERBEARING REGULATION. *TR

The pretensioner cable that secures the end of the seatbelt to the seat frame had severed. I am told the pretensioner has a small explosive inside its barrel that I assume releases some sort of spring internally upon impact of a collision. The release of this spring is supposed to pull the pretensioner cable downwards and by extension pull the seatbelt end tighter. This in conjunction with the seatbelt retractor would then keep the driver or passenger tight to the seat in the event of an accident. I notice the cable for the driver side pretensioner over the last few months had strands of steel breaking until it had finally completely severed. I have kept both halves of the severed cable if inspection is requested. This is an extremely unsafe situation to occur. Had I gotten into an accident with the cable partially or completely broken it would have rendered the seatbelt essentially useless. There were no warning lights or associated codes ever displayed from the vehicle’s computer. There were no inspections done by insurance, police, manufacturer, dealership or any others. I ended up ordering the part online to fix myself. I used all manufacturers torque specs and procedures to replace. I fixed it myself because it was my daily driver vehicle and I needed to have it working safely as soon as possible. When I noticed the cable had completely broken I drove my vehicle home and did not drive it again until I had the new part and it was replaced which was about two weeks later. I had asked the dealer and searched for recalls for my vehicle and neither the dealer nor the nhtsa recall search showed anything regarding issues with the pretensioner cable. I did end up seeing GM had issued a recall for a similar pretensioner cable (about 2500 vehicles) for a few of their full sized trucks and SUVs. The claim was based on where the cable was in the vehicle it had abnormal amounts of metal fatigue from drivers exiting and entering. I believe the same issue happened to me.

Overall and to the best of my knowledge, the malfunctioning and failures on my vehicle were the suspension and engine. They are the culprits and it’s honestly very scary and traumatizing to have them completely fail, especially since no one is ever prepared for accidents and/or potential death to happen. Otherwise it wouldn’t be called an accident. With the suspension overall, it’s just awful. CV Axel, control arms, everything with the suspension just failed. With driving over the tiniest bump on the road you feel your is about to literally fall apart at any minute because of the clunking and metal in metal noises it produces. The engine is faulty as well and I am pretty sure the faulty engine happens due to the faulty suspension. When I look under my car there’s something leaking. I don’t know what it is, but it’s poses a safety risk not only for the driver and the passengers, but also to the rest of the world. I know that there was a recall early on about fuel tank breakage or something that could lead to fire ignition. But my vehicle according to my VIN wasn’t on this recall. I have contacted the dealership and a certified service center to inspect these issues. It’s been roughly 4 weeks now and they have been extremely negligent and apathetic. With these issues, everyone’s safety is at risk. My suspension went out and could’ve caused a more catastrophic accident. A fire could’ve broken out with other vehicles surrounding me cause major injuries and death. I’ve seen and read many posts and testimonials and threads online from various independent resources that state very very closely the same issues. Almost verbatim. I’ve been trying to get these issues inspected by the dealership, but they all give me the runaround and don’t want to fix not find a solution. The check engine light has always been on since I’ve Owen the vehicle and the dealership where I purchased this vehicle said having the check engine light on is okay. I need help getting repairs done!

THE DRIVER BACKED OUT ONTO THE RESIDENTIAL STREET. THE DRIVE ALIGNED THE WHEELS TO POINT STRAIGHT DOWN THE STREET. THE DRIVER SHIFTED INTO DRIVE AND PRESSED PRESSED THE ACCELERATOR. THE CAR RAPIDLY ACCELERATED AND SWERVED TO THE LEFT. IT GRAZED THE BUMPER OF A PACKED CAR AND CAME TO REST ON A TREE. UPON LEAVING THE FRONT LEFT TIRE WAS DEFLATED. THE REPAIR SHOP REPORTED LEFT SUSPENSION DAMAGE. *TR

I WENT TO ADJUST THE TEMPERATURE GAUGE TO DEFOG MY FRONT WINDOWS AND I COULDN'T MOVE THE KNOB. I ALSO TESTED THE VENTS TO FIND OUT WHERE THE AIR WAS COMING OUT OF AND THERE WAS PRACTICALLY NOTHING COMING OUT OF THE VENTS. IT TOOK A WHILE FOR MY WINDOWS TO GET CLEAR WHILE I WAS DRIVING ON THE HIGHWAY. *TR

NEW HANKOOK OPTIMO H428 TIRE ON MY 2014 SONIC DEVELOPED A BULGE ON THE FRONT DRIVER TIRE. DEALER CLAIMS IT WAS DUE TO ROAD HAZARD. RESEARCH SHOWING THAT THIS IS A COMMON COMPLAINT FOR THIS COMPANY'S TIRE. NO KNOW HAZARD WAS HIT TO CAUSE THIS. TIRE WILL HAVE TO BE REPLACED BEFORE A BLOW-OUT OCCURS, POSSIBLY CAUSING AN ACCIDENT. *JS
