Engine leaks/burns oil too frequently. Every other week I-??m continuously having to put oil to refill levels. Also electrical system for turn signals is always going in and out. Sometimes it works and sometimes it doesn-??t. Safety hazard because other vehicles can-??t tell that I-??m turning.

We bought this used car for my daughter, then I found out there was issues with the engine. We had it for 6 months and the engine seized as she was driving it on the highway. She got to pull off to the side of highway. We had it towed to our mechanic, hoping it was the battery or something simple. He told us it was a blown engine and there was PLENTY OF OIL AND ANTIFREEZE IN IT. HE THEN TOLD US THE HE LOOKED AT IT AND COULD NOT BELIEVE IT WAS BLOWN, WITH THE OIL STILL IN IT. WE had to buy a new rebuilt engine and pay for the mechanics time. There has been issues with this engine-??s. How do we get the engine payed for, with the problem they have. This wasn-??t a neglect part on us. I would like to get REIMBURSE FOR THE NEW ENGINE ( rebuilt ) not our neglect, but the way they built the engine / oil pan

My 2011 Hyundai sonata Engine failed in April 2023. Was towed and the engine was replaced due to the recall. Got car back November 4th 2023. Fuel gauge never went out and after driving about 3 miles the engine light came on. Dec 13th was driving on highway and felt like the car was going to fall apart. Able to get off highway only for the car to die. Every light including some I have never seen came on. Was stuck on the side of the road with my ESA dog in 28?. Temp. For over an hour with no power and hazards starting to dim. I'm disabled and had no help. Local PD towed vehicle and drove me home. Car sat at tow yard collecting fees as I was waiting for the dealership to call me back. Finally got help with paying the tow yard company only to be stuck once again for over an hour in the cold and then denied a tow to the dealership since they decided to cancel my appointment by text while I was on with Hyundai roadside assistance. They denied any help. Luckily the tow yard felt bad and made a call for me and a friend came and paid the $160 tow truck to get the car back to my house. They have now not returned my calls and the case manager has not responded as well. This is unacceptable. I don't have any money and I have no idea how they can get away with treating a disabled person in the winter days before Christmas by letting me be stranded twice on the side of the road with an engine that has less than 10 miles on it.

I have a problem that Hyundai is known for Hyundai oil consumption. I bought my car into a nearby shop for service because my car shut down while driving on the highway. The shop advised me the engine was full of oil.

I was driving in the middle lane of the NJ parkway going 50mph and the car stalled. I was able to coast to the shoulder and have the car towed to my mechanic. Today I was information the engine is dead and I should contact the dealer. This a replacement engine as the first engine died while driving when the car had 70,000 miles. Hyundai replaced the engine but at 90,000 miles the replacement engine died. I'm wondering if you have reports of this happening. unfortunately the class action suit will not cover my 2011 Hyundai Sonata with 160,000 as it is over the years and mileage of the warranty. The warranty did not start at the time and mileage of the replacement engine but at the time of orginal purchase.

I started to get engine knocking noises about 6 months after the purchase of the used car. This knocking noise began to increase in frequency as I pressed my foot on the accelerator and the car would not accelerate when I pressed my foot on the gas pedal. Then the car would shut down in the middle of traffic. After waiting about 30 -45 mins, I would try to start the car again and would start and initially run as long as I drove less than 20 miles/hour the knocking noise level would decrease but if I went above 15 - 20 mph the car would shut down. The check engine light and engine oil light would come on. So I would check the engine oil level oil using the dip stick and it showed oil levels were ok. On October 10 2023 while driving to Walmart the engine turned off and would not start after waiting over 1 hour and I was stuck in the mall entrance road. A concerned driver with his passengers pushed the car to a Walmart parking spot where it is currently at. In addition, the traction light kept coming on and I paid the Hyundai dealership $2,800 to repair to keep the car from drifting to the left and to get the light off.

My car had engine seized while driving on the road with no warning light prior nor other mechanical issues. When the engine seized, all mechanical powers are have lost power including brakes and power steering in which have almost caused a near accident at an early morning rushed hours. The vehicle's odometer reading at 120,836 and was up to date on all normal tune up performances. Other issues that have arise after purchasing the car are: warning light came on for airbag, real loud clunking sound on roof when hitting a bump on the road and engine will not start because of fuel line system issues. Cruise control had also stopped working after a year of purchased.

We bought this 2011 Hyundai Sonata from a local dealer in August 2021. The engine failed in March of 2022 (smoking and then died while my daughter was driving the car). We paid a local mechanic to replace the engine with another used engine, not knowing the engine issues associated with Hyundai Sonata models, specifically the 2011 year. The replaced engine died in July 2023, about 5 months later. The warranty we had on the replaced engine was denied to due to a heat tab melting. The first engine (to us, we do not know if was replaced during the 2016 recall) and now the replaced GDI engine have both died. The engine should not be on the market and we contacted the local Hyundai dealer to see if they could help us out. They denied service because we replaced the engine ourselves with another mechanic. This is a critical safety issue and Hyundai should be held responsible to get these engines off the market and reimburse customers for all expenses related to the repair or replacement of the engines regardless of where it was fixed. Now there is a new recall related to these engines https://apnews.com/article/hyundai-kia-engine-fire-recall-park-outside-93d012a52e7b884889cdaf2e6c22a458, where customers are being told to not park in structures due to fire hazard/risk. And I read recently that Hyundai has been slow to recall cars and fined by NHTSA for this very reason. Our model is not currently in an open recall, but it doesn't make sense that both engines failed...both GDI engines. This should be addressed by Hyundai and we should be reimbursed for the expenses paid by us to fix their poor engine design and the safety issues associated with this make/model/year.
