2017 HYUNDAI SONATA HYBRID Engine Problems

The engine shut off on the highway on two different days. Vehicle was going between 65 and 70 mph. The vehicle engine shut down and all the warning lights came on. Every one. The vehicle still moved but nothing inside worked, it ran on battery mode for the 17 miles to the dealership with a maximum speed of 60 mph. The risk was the immediate unresponsiveness of the vehicle and the sudden and immediate reduction in speed and power. It presented itself twice in about 2,000 miles. The dealership charged a 491$ diagnostic and found all the warnings and reset it, not reason for it happening and sent me on my way. Then it happened again. Brought back to the dealership and they tried to say they did another diagnostic and called the tech helpline. It took hours and they still don’t have a definitive answer, wanted to try almost 2k in repairs to see if it would fix the issue without any guarantees it would. Warning lights, all of them came on, cruise control, abs, engine light blinking, steering, literally everything and messages started running through the information center.

FAIL/MALFUNCTION 3/18/25: Internal engine failure diagnosed by local Avondale, AZ Hyundai dealership service - rod bearing failure suspected. Vehicle currently undergoing Bearing Clearance Test to affirm this or any connecting rod issues, with possible need for total engine replacement. When googling "Hyundai Sonata hybrid 2017 internal engine failure," masses of reports generate from consumers with this model, complaining of same defect, as do numerous recalls for such defects that have been mandated for the model with range of years including 2017.Yet when searching with my VIN, it says no recalls have been mandated, in spite of the undeniable, widespread identical defect. Available for inspection. SAFETY RISK: Driving on the freeway in city traffic at 70-75mph, the engine completely stopped and all dash lights lit up at once. Vehicle had to be coasted to shoulder to wait for roadside assistance. Extremely hazardous to us in vehicle and to all around us with sudden, dramatic speed change in moving, constant freeway traffic. First time: Our usual mechanics at Pep Boys did diagnostic but found nothing, the vehicle drove normally for them, yet they did our regular tune-up, oil change, etc. Two weeks later, the same event happened on freeway, identical to first time. We were very lucky that no crashes happened either time. Pep Boys advised that Hyundai investigate the issue. PRIOR SYMPTOMS: No warning lights or sounds presented until the events themselves, when the entire dash lit up. However, in the couple of months before, there were occasional, slight hesitation moments in the motion while driving at any speed. CONCERNS: 1) It seems Hyundai is on track to want to charge me for an entire engine replacement, or for whatever engine repairs they deem, e.g. connecting rods, for manufacturing defects that they are entirely responsible for, 2) no recall seems to be mandated YET for this VIN batch, and 3) too many consumers are in danger - physically and financially.

The vehicle had a recall to replace the motor for bearing failure. They replaced my motor at 101,000 miles. The second motor than failed for the exact recall of bearing failure at 65,000 miles on the new motor. They told me that since I had already have done the recall and my car was now out of warranty that I would have to pay 10% of the repair bill for another motor. This second motor should have been included in that recall.

The contact's son owns a 2017 Hyundai Sonata Hybrid. The contact stated that while her son was driving at an undisclosed speed, he smelled a burning odor on the interior of the vehicle, after which he heard an abnormal sound coming from the engine compartment. The check engine warning light was illuminated. The vehicle was taken to the dealer to be diagnosed; however, the contact was not aware of the diagnostic report. The vehicle was not repaired. After investigating the failure, the contact related the failure to NHTSA Campaign Number: 21V727000 (Engine); the VIN was included, and parts were available. The contact also stated that the vehicle had a Salvage Title. The manufacturer was not notified of the failure. The failure mileage was 66,000.

ENGINE OIL MISFIRE ALSO NOTED AS A RECALL ON THE 2016 MODEL AND REPEATEDLY MENTIONED ON LINE AS AN ERROR IN THE 2017 MODEL NOW REACHING SIMLAR MILEAGES. DEALER IS REFUSING TO ACKNOWLEDGE IT AS A PROBLEM AND SAYS THE ENGINE LIGHT SI NOT RECORDING THE ERROR AND YET AN OUTSIDE ANALYSIS SAYS ITS ERROR 0302!! THE SAME AS THE 2016 RECALL NOTICE. THE 2017'S SHOULD BE RECALLED FOR THE SAME FIX

While driving, car started to lose power. Warning lights started flashing to turn off vehicle to recharge battery. Car lost all power. Car was towed to dealership. Dealer started diagnostic testing, and first thing that was noted is that all oil had drained from car and that crank shaft may now be damaged. Prior to incident, no warning lights came on for service, engine or oil lamp. Dealer and internet searched confirm this has been happening to this model recently.

This is the seventh occurrence of complete loss of power while driving on the interstate. The hybrid system warning activated, followed by the engine shutting down, and all dashboard lights illuminated with alerts indicating "Shut Off Engine/HEV." An 18 wheeler was pulling out from the shoulder as I was losing power and barely missed getting crushed. The former problems have all been at interstate speeds with similar accident avoided. The service history clearly demonstrates that Hyundai has repeatedly attempted to address this issue by replacing numerous critical components, including the engine, transmission, knock sensor, battery (three times), integrated brake actuation system, and smart cruise control, among others. Despite these extensive repairs, the problem persists. On this latest occasion, less than 4,000 miles and four months since the last major incident, the dealership has proposed replacing the intake manifold, EGR valve, HSG belt, and spark plugs. The belt was changed less than 20K miles ago. and I believe the spark plugs were as well. Each time my vehicle experiences this issue, it is out of commission for weeks or even months at a time, causing significant inconvenience and raising serious safety concerns. I no longer trust this vehicle and I don't believe the many recalls have successfully addressed the root cause of issues with the 2017 Hybrids.

While driving on the highway, the car loss. The dashboard noted the Blindspot Detention System failed and the dash noted "Hybrid System Warning. Turn off Engine." The vehicle was towed to the dealership. They confirmed a Knock System Sensor had to be replaced. Less than a month after the repair, the same issue occurred on the highway again and the vehicle was towed to the dealership. Vehicle has been at the dealership for over 2 weeks and dealership has confirmed they haven't been able to accurately diagnosis the problem yet. Both incidents have occurred after the dealership addressed the recall campaign related to the engine.

EGR cooler leaks and slowly burns off engine coolant resulting in the car overheating while driving, forcing a quick exit from the road, or stopping in traffic not to damage the engine. Google search shows this is a very common issue with these hybrids.

Excessive oil consumption. Engine makes knocking sound. Check engine light and/or oil light come off & on. Over heat light & HEV LIGHT. Bought car brand new in Sep2017. December 2017 car was in shop for a month. Ever since that incident, car has been in & out the dealership for same issues. Car has been serviced only by Hyundai dealerships. Currently my car has been in the shop awaiting repairs since end of February 2024. I keep getting the delay in parts excuse. Hyundai claims my car does not fall under their lawsuit for engine replacement nor do they acknowledge faulty engine oil consumption.

2017 Hyundai Hybrid Sonata lost power while in the middle lane of [XXX] . Following notice appeared: Check Hybrid system. Turn off engine !HEV. We were able to coast over to side of road (car was going 70mph at time of breakdown). Car towed to McDonough Hyundai dealership. Talked to Service Dept. We explained our situation to him (out of town, spending money on a hotel). They performed an engine electric Diag. which stated: Vehicle had multiple codes for low battery voltage. Test battery and got an instant failure. Cleared codes and test drove after new battery replacement. No codes came back. Approximately 1 hr. later in Jackson, GA we were on [XXX] , middle lane & engine stalled (70mph & coasted over to side of highway). Received same code: Check Hybrid Battery System, !HEV, turn off engine. Had car towed to Kennesaw, GA. Rented car to drive home & had car towed to Alexandria, KY our home town. After 2 wks. car was put on diagnostic machine. Said they test drove car multiple times. They said could not duplicate the issue. It was suggested the next time we get code on our dashboard to take a picture of it or video. Took car to Kerry Hyundai, Florence. Test driven car 40 miles & have gotten nothing. No codes. Told them it was imperative that your mechanics find the issue. I will not drive the car as it is now. It is unsafe as it stands now. Breaking down 2x in GA. The first time after driving it 6.5 hrs. and the 2nd time after putting brand new battery in & breaking down exactly 1 hr. after driving. We have been without our car since [XXX]. Hyundai advertises a great warranty on their cars, one reason we purchased it. We wanted a SAFE, RELIABLE car since we are both retired and going to travel. We are out of $1,827.08 & afraid to drive car. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

This issue has happened twice in one month on my Hyundai sonata hybrid that I’ve had for less than 3 years. It is a 2017 model. While driving on the interstate, the car will stop accelerating and all warning lights will come on along with “Check hybrid engine. Turn off engine”. The dealership has yet to find out the problem and cannot tell me what the issue is both times I’ve brought it in (it’s had ti be towed both times). I cannot afford to keep paying for repairs on an almost new car along with the safety concerns of driving it. I am attaching pictures of both times it happened- noting that it is the same warning each time. It looks like multiple owners are having this issue and none has yet to be resolved.

The car started shaking or not running smoothly back in May and then the check engine light came on. I immediately pulled over and inspected under the hood. I saw nothing wrong and the car started fine and check engine light went away. I drove a few more days without any problems but then the same thing happened again. The next day I called the dealership (Bob King Hyundai in Winston-Salem, NC) the earliest appointment was 26 days away. I had no choice but to keep driving it even thought I was terrified every time. It happened a few more times and I took it by Auto Zone and they gave me a DTCs Secondary code of P0303 Cylinder 3 misfire detected No Code(The gentleman informed me that to get a code the light would need to stay on. I told this to the dealership when I took it in for service and diagnosis on 5/30/2023 They called me on 6/1/2023 and told me the mechanic could not find anything and that it could be a vaccum leak and they can clear themselves. About 2 days latter it happened again. I called the dealership back and ask that the Service Manager call me and He still has not called me. I also reported this to corporate Hyundai and that Gentleman stated He could not get in touch with anyone about the issue either. I went ahead and made another appointment which is now scheduled for 8/10/2023. I took it to O'Rielys and they told me the same thing that Auto Zone did Cylinder 3 misfire. I have replaced the gas cap with Hyundai but that didn't help.

My wife and I have been having an intermittent but constant problem with our steering mechanism which our dealer says they cannot replicate and therefore cannot resolve. This constant problem is one that MANY Sonata Hybrid owners have reported online. Our experience is having the steering wheel seize, flashing lights during which the red steering wheel icon with an exclamation point remains on. Our experiences have been in our mobile home park when we are turning left. The last two incidents were when we were blocking our street and vehicles could not pass. A prominent feel in the steering wheel of clicking, clunking, and play in the wheel accompanies these incidents. I had to, as others, to turn the car off and restart to carefully, amidst clicking and clunking, to return the car to our driveway where it will sit until we take frontage roads to our dealer. We recently received a notice from Hyundai that the steering wheel mechanisms' warranty has been extended 15 years from the ending date of the original warranty. The notice indicated that our Sonata Hybrid "may exhibit reduced power steering assist and/or motor driven power driven steering (MOPS)." We believe this is suggesting that MANY complaints have been sent to various authorities regarding this same issue. We now have a much delayed (due to our dealership's backed up service appointments) appointment to again address this problem which they say is not happening because they cannot replicate it. Many online comments indicate that people are scared that themselves, loved ones or others will be involved in a fatality due to this "intermittent" problem. We could not find a Hyundai Regional Manager with whom to correspond. We feel abandoned by Hyundai but hopefully not by the NHTSA.GOV. We are scared and disappointed. Is Hyundai really "committed to providing vehicles of outstanding quality and value" as its August, 2022, EXTENDED WARRANTY NOTIFICATION said. Please help. Hyundai dealers won't.

Motor issue. Took vehicle in for routine service. Hyundai Sonata Limited Hybrid year 2017. Purchased and took possession of vehicle in May 2018. Purchase New. Current miles 41,000. When doing routine service, tech discovered that head gaskets were now damp and indicating coolant fluid leak. 1) Failed component - head gaskets. 2) Safety risk - none at this time. Car is functional and operating normally at this time. 3) Dealer discovered issue. 4) Vehicle has not been inspected by someone other than dealer. Exclusive dealer service since purchased. 5) No warning lights or any other such indication of failure. No leaking or wet spots under vehicle when parked. Dealer at this time ordering parts and to schedule service repair. Have called Hyundai and filed a claim on this matter. Concern is that there is a prior recall for the motor regarding internal bearing failure. At that time, vehicle was inspected for this recall and was determined that there is no defect/problem existing or in progress. I am desiring that Hyundai replace the entire motor and not just repair due to the known other mechanical recall. As of this time, there is no determination made on my request.

After travelling on the highway for approximately 1 hour the HEV light along with several other lights came on and the engine powered down. The instructions were to turn off the engine immediately . Luckily I was in the right lane and was able to get to the shoulder of the highway and turn off the engine. Tried several times to restart, but same message came up to turn off engine. Had it towed to closest Hyundai dealer for service. They couldn't look at it immediately, but according to them it started the next day and they drove it around (local driving) for 10 miles with no issues. I took the car back and after driving it again on the highway for 1 hour the same problem occurred and I had to have towed to my local Hyundai dealer. It has been in their shop for over 3 weeks and I still have no answers as to what may have caused the problem.

ABRUPT AND TOTAL LOSS OF ACCELERATION AT FULL THROTTLE AT OR NEAR HIGH RPM SHIFT POINTS. THIS BEHAVIOR CAN BE RELIABLY REPRODUCED BY "FLOORING IT" (ALL THE WAY, INCLUDING KICKDOWN) AND NOT LETTING GO - AS IF ONE IS EXECUTING A PASSING MANEUVER. THE POWER LOSS WILL OCCUR AT THE NEXT SHIFT POINT AFTER KICK DOWN, AND WILL NOT BE CLEARED UNTIL THE ACCELERATOR PEDAL IS RELEASED AND RE-APPLIED - OR AFTER APPROXIMATELY 15 TO 20 SECONDS AFTER THE OCCURRENCE IF THE DRIVER DOES NOT RELEASE THE PEDAL. IN CASES WHERE THE PEDAL IS NOT RELEASED AFTER THE POWER LOSS, THE VEHICLE WILL SURGE SUDDENLY AFTER THE CONDITION HAS CLEARED AND REPEAT THE BEHAVIOR DESCRIBED ABOVE. THIS BEHAVIOR CAN BE REPRODUCED IN ANY DRIVE PROGRAM MODE (ECO, NORMAL, SPORT, ) AND IN BOTH AUTOMATIC AND MANUAL SHIFT SELECTION MODES, AND IS ESPECIALLY PREVALENT AT SPEEDS ABOVE 45 MPH WHERE SUDDEN FULL THROTTLE COMMAND CAUSES KICKDOWN. THE DRIVETRAIN SHOULD RESPOND RELIABLY WHEN IT IS COMMANDED FULL-THROTTLE. A SUDDEN POWER LOSS AT A SHIFT POINT DURING A FULL THROTTLE MANEUVER IS UNSAFE: (1) IT DISORIENTATES THE DRIVER AND; (2) CAUSES UN-COMMANDED, UNEXPECTED, AND RAPID CHANGES IN DRIVING FORCE, WEIGHT DISTRIBUTION, FRICTION, AND REACTION FORCES WHICH COULD LEAD TO A LOSS OF CONTROL.

WHILE DRIVING ON A 4 LANE STREET THE CAR SUDDENLY GAVE A MESSAGE 'CHECK HYBRID SYSTEM SHUT OFF ENGINE'. I WAS STOPPED AT A RED LIGHT SO I TURNED OFF THE ENGINE. WHEN I TRIED TO RESTART THE CAR IT WOULD NOT START. IT TOOK 4 TRIED TO GET THE CAR RESTARTED. LATER THAT NIGHT THE CAR WOULD NOT START AT ALL AND I HAD TO HAVE IT TOWED TO THE DEALERSHIP THE NEXT DAY. THE DEALERSHIP COULD NOT FIND A PROBLEM AND I RETURNED TO GET THE CAR. ON THE WAY HOME FROM THE DEALERSHIP I HAD SHUT OFF THE CAR TO RETRIEVE SOME ITEMS AND UPON RETURNING TO THE CAR AGAIN IT WOULD NOT START. ALL OF THE INDICATOR LIGHTS ON THE DISPLAY PANEL WERE LIT BUT THE CAR WOULD NOT DRIVE AND THE SHIFT LEVER WAS LOCKED. RETURNED THE CAR TO THE DEALERSHIP AND THEY REPLACED THE HPCU MODULE. I GOT THE CAR BACK AT THE BEGINNING OF SEPTEMBER AND TWICE IT HAS FAILED TO START. EACH TIME THE DASHBOARD INDICATOR LIGHTS WILL LIGHT UP BUT THE ENGINE WILL NOT START.
