2011 HYUNDAI SONATA Complaints

I was driving down the road going the speed limit and all of a sudden it felt like I hit a brick wall my car staked out and I was stuck in the middle of the road for about 20 minutes and finally I got it to start and drove home it did it again 2 months later

I had taken my Sonata to Mike Miller Hyndia in Peoria,I'll and they agreed to do the recall although they had my vehicle for two weeks. They did not service it and when I picked it up they said I had to drive it till the service engine light come on. I was driving it five days later and heard a loud noise and car started malfunctioning I was stuck in a middle of a intersection and I had to push vehicle off road. I broke my right hand in this process and I have also lost my job I am very concerned why they did not service it after they agreed too and sent me off in it in that condition ..The car is currently parked and unsure what to do with it ..

The contact owns a 2011 Hyundai Sonata Hybrid. The contact stated that while driving at an undisclosed speed, there was an abnormally loud sound coming from the vehicle. The contact turned off the vehicle, and while inspecting the vehicle, the contact became aware that there was a puddle of oil on the ground underneath the vehicle. No warning lights were illuminated. The vehicle was taken to a nearby Ford dealer, where it was diagnosed with camshaft and engine failure. The contact was informed that the camshaft and the engine needed to be replaced. The vehicle was not repaired. The contact was informed of Technical Service Bulletin: 22-EM-006H-2. The contact was advised to tow the vehicle to a Hyundai dealer for assistance. The vehicle was towed to an alternate dealer where the failure was confirmed. The vehicle was not repaired. The manufacturer was made aware of the failure, and a case was filed. In addition, the contact was informed that the repair was not covered under warranty. The contact was informed that the repair was denied because of the previous owner's negligence with maintenance of the vehicle. The failure mileage was approximately 120,744.

The vehicle suffered an internal connecting rod bearing failure, a known manufacturing defect affecting the Theta II GDI engine. The failure was explicitly diagnosed via the manufacturer - specific OBD-II fault code p1326 Knock Sensor Detector System. This defect causes sudden engine stalling poses an immediate risk of catastrophic engine failure or fire while driving. Hyundai Motor America has denied financial reimbursement for the required engine repair because the work was completed by an independent shop and third-party arbitration deadline (BBB Auto Line) communicated to me. The manufacturer is actively refusing to remedy an acknowledged safety defect.

On the freeway at night when headlights and back lights quit working. Got off freeway and were able to temporarily fix it. A few months later while parked in driveway and not in use for a couple of days, lights came on without our knowledge and drained our battery. Neighbor alerted us to the situation.

Intermittent and sudden loss of power steering nearly caused an accident for both of sons when each one was driving on two separate occasions this past week. "EPS" and traction control warning lights both illuminate on the dash when steering goes out. Sometimes the codes will clear themselves out after restarting the vehicle, but not always. Had it inspected by an independent service center and they cleared out the codes with their scanner. Steering worked fine for a few days afterwards, but then suddenly lost power steering again yesterday. It is very dangerous to drive and it is very unpredictable. I see that there was a recall for this issue for certain manufacture dates for 2011 Hyundai Sonata, but mine was not part of the recall. I believe that it should be part of that recall before someone dies or is injured.

I test drove the vehicle at an auction, watched several other people test drive the vehicle. Before the auction I test drove it one more time and put my obd scan tool on it to make sure there were no hidden codes or problems. I won the bid,and picked up the vehicle. I drove it approximately 6 miles from the auction and the falshing engine light popped on. I immediately pulled over in heavy freeway traffic. Put my scan tool on it and found out the knock sensor had triggered. The vehicle was shaking and making a terrible racket. It was inoperable in the worst possible spot on Highway 51 during rush hour traffic. I managed to slowing coast down the offramp and roll into a parking lot. I then called Purdy Hyundai and spoke with a service advisor and provided the VIN#. He (Vue Kue) informed me that the vehicle qualified for the recall and warranty work based on exactly that issue. I had the vehicle towed to the Purdy dealership on July 8th 2026. I was told today that it was unlikely that Hyundai would honor the recall because I did not have service records of a vehicle I had owned for 6 miles of driving. I filed a complaint with Hyundai corporate. Claim#43010067 and awaiting the reconciliation of this situation. Of which they appear to to be avoiding.

I purchased fgis car from a used car dealership, for over $6,000.00 , which is not a ton of money, but plenty enough to not have instant issues. Since my purchase in june 30, 2026, i have already had all of these issues occur. There is white smoke coming from the left tail pipe, it is sluggish when you push on the gas, there is black soot constantly on my rims that is extreamly hard to remove, the high pressure fuel pump jas failed, I can tell because the oil is higher then it was when o had the oil freshly changed, and it smells of gasoline.inside the oil. The exhaust has stron smell of gasoline. My steering wheel has a loud clinking noise everytime I go over a speed bump on pull into my driveway. Just so many items consistently needing repair or replacement, even though I just had the fuel system cleaned, the oil changed, and filters, and.oil filter too. I checked to see if any of my issues are covered by a recall warranty, because they all are recalled items for my car year, make, and model, but apparently Hyunfai is only covering these dangerous recall items for ul to 10 years. These items shkuld be covered longer, because my carfax states that at least one of these recalled items had already been changed in 2018, and is already broken again!! Hyundai should have covered these extreamly high wear out car parts for a longer period of time, or for the life of the vehicle, if every 5 years your replacing a $1000.00 part, not including labor, like the (HPFP) I was quoted by auto zone for over that price point!! "Ridiculous"! Another item is the air bag cover on the driver side windows area, of the body frame it is loose and keeps un-clipping, i am afraid that it is going to possibly just go off and kill me or something!! Very disappointed right now, that i cannot get any of these recalled items replaced by the manufacturer!!

I was heading to work when suddenly smoke started pouring from the air conditioning vents, and the ABS and traction control warning lights came on. I hit the brakes to pull over, only to realize I had lost braking power. I managed to steer to the side of the road as carefully as possible and bring the car to a stop—despite having no brakes and a fire burning under the hood. I tried downshifting to slow the vehicle, but the transmission didn't respond, and the cabin began filling with smoke. Once I stopped, there was nothing I could do to extinguish the fire, as the car was completely consumed within seconds. It was a fire in the engine bay; I lost the brakes, and the ABS and traction control lights lit up. I assume it was a critical failure in the braking system, most likely involving the ABS module.

Rod bearing issue due to particles in engine causing engine to not accelerate as normal and jerk when goes over 10 MPH can’t exceed 50 miles causing safety issues and knocking/clicking noise took it to Hyundai and was informed it is apart of the recall but wont replace engine my vehicle has ALL the same issues as the Hyundai recall but my VIN isn’t registered on the site for recall on carfax it shows a pattern of the previous owners being car in for maintenance and engine issues but engine never being replace under recall
