Last year in March 2021 I have a problem with the oil and the engine. The oil is burning internal and the engine wouldn't go pass 60 miles. This was reported the McGrath City Hyundai in chicago. A whole year they had me to bring my car in to them saying that hyundai need pictures and other stuff. I was told to keep driving my car 1000 miles and that did no good at all. Every since then my oil light been coming on and off. Now my engine light has pop on on today April 17, 2022. I was told by the Manger at McGrath City Hyundai that I was decline for a engine. I have been getting my oil change with them for the longest. I feel discriminated against because I am a female and they had me bring my car back and forward up there to keep topping off the oil in the car and know there is a problem with the engine, they kept my car for two weeks and didntgive me a rental and the car is still doing the same thing loosing oil there was a recall on Hyundai Engine it's been all in the papers and on the news they also sent out recall letters and they are refusing to replace my engine

I have a 2.4L 4 cylinder enginr.lI noticed that I would get my oil change and a few weeks later my oil light would come on and I would have to add oil. This had been going on for the past year with no one able to provide an explanation. About a month or so ago, my car began to violently shake, , loss acceleration and my check engine light came on. A mechanic looked at my vehicle advised he saw oil on all my spark plugs and said the 3rd chamber was losing compression. Doing some research I found out that the engine in my car has a recall for defective connecting rod bearing issues. The dealership is telling me that is not the issue even though the have not broken down the engine as the issue could be due to the recall....I need help I am without a car and my warranty has expired.

Vehicle-??s engine began to emit a knocking sound that would increase in volume and speed as engine progressed in speed. Engine suddenly lost power, check engine light began to flash and traction control disabled itself. Vehicle was pulled over and turned off when it immediately began to rapidly self immolate over the course of minutes while the power to the engine was completely disabled.

The vehicle is available upon requested inspection. Since I bought the car in 2019 it has made a rattling sound like the engine is knocking. Not a severe knocking, however, it does make a clicking/rattling sound in idle, occurs more rapidly while accelerating, then sounds like a muffled diesel while the engine-??s torque is dropping when shifted into neutral coasting on the road. Oil has been changed in its due time. Between 3k - 7k as scheduled. Independent service provider didn-??t think it was normal and recommend I check for recalls. I asked Hyundai dealership representative and said it-??s a normal sound. Other vehicles I-??ve driven don-??t sound like this. Even an older -??96 Buick sounded smoother running. Nothing has failed, caused an injury or accident. Engine light has recently come on. Temperature is hotter, according to the gage, than we-??re it has typically sat for the past couple years. The potential risks increased, not knowing what can happen, when the temp rose and engine light comes........... This, aside from previously stated concern, alarm activates (mostly during the rainy cloudy weather) when manually unlocking the car. Having to relook and unlock to silence alarm.

The oil burns way to fast in these cars because of the engine there should definitely be a recall to asses this situation as I-??m not the only one with this problem. This is a problem for Hyundai owners as you have to replace your oil even when the car states you have about 3K MILES left before a refill.

The engine started knocking on the freeway and all the lights in the car went off. The engine failed and I barely made it off the freeway. I was almost hit by two cars trying to get to a safe place. The engine has the same issue as the other morsels that have recalled the engine for the same rod failure issue but Hyundai has not extended the recall to the plug in hybrid. This model also bends to be recalled because it is a danger to all owners and other drivers. Hyundai declined to repair the defective engine.

My car was driving just fine then it wasn-??t accelerating right and it went into limp mode. I was about 12 miles from home. I made it but the next day on the way to the dealership the engine just died about a mile from my house. Engine light came on. I always get my oil changes on time. Dealership says engine oil is sludged due to negligence. No negligence I believe faulty engine caused containments and have very bad oil consumption. My theta engine was left out of the campaign and my warranty was denied.

In May 2021, the car began using excessive oil powered down with engine knocking, ticking, and missing when acceleration was tried. We regularly change the oil and it was using a quart of oil every 2,000 miles. We took it to Hyundai and they reset the chip. In February of 22, the engine began knocking and ticking. It powered down and the engine light came on. We had put oil in it over the weekend as we have to do now weekly as it is using excessive oil. After only 500 miles, it powered down in safety mode and began knocking and ticking with no acceleration. We had the oil changed early, but it did not help. I was in safety mode for 76 miles on my way home from work. It has 163,000 miles on it and is only 6 months from pay off.

On January 8, 2022, I called McGrath City Hyundai and Genesis of Oak Park to ask about any recent recalls on my vehicle due to my engine leaking out oil after putting in new oil. Prior to that, I had a mechanic look at it in case the oil change place made a mistake on their end and found they were not at fault. So after the Hyundai dealership told me there was 2 recalls that she can see from her end based on my VIN, 1 for the engine and the other for the trunk, we set up an appointment to try and repair the vehicle because at this point the vehicle was not drivable and we had to get it towed. We also had no prior knowledge that there was any recall due to the fact we bought the vehicle in May of 2020 from a dealership called Toyota of Lincoln Park. After bringing in paperwork to Hyundai in person for proof we have been maintaining the car and after waiting weeks for our car to be fixed, we are being told they cannot fix the engine due to the fact that the recall was from 2018 and the previous owners did nothing to resolve the issue. We were also told that the dealership that sold us the vehicle cannot look up recalls from other vehicles and only can do it with Toyota. The car had already almost failed on the expressway and could have caused an accident had we not pulled off to the exit. And we were fortunate enough to get it to our home. The engine wasn't locked up and we feel now it might be while in the hands of Hyundai. Hyundai has denied the claim to have it serviced due to it being a 2018 recall and all we want is the car running again. We cannot afford to get another car and it is our only means of transportation.

Purchased this car brand new in 2017 from a Hyundai dealership. Started having issues with it 2 years later and up to now. The engine light is consistently illuminated, the oil light comes on within about a few weeks of having the oil changed with just local neighborhood driving and I have to have my oil changed every 4-6 weeks when even just driving no more than 20-30 miles a week, the mechanic who does my oil changes stated there is no oil leak but the oil stick keeps coming up BONE DRY which results in costly oil changes on a extremely regular basis. The engine has been and continues to do a very hard almost violent knocking that is so strong it can be seen from the outside of the vehicle and has affected the way i have to drive the car. The engine hesitates to take off and according to several mechanics who have looked at the vehicle it keeps misfiring because of oil pooling in the spark plugs that has been changed on a regular monthly basis now. There is a large amount of smoke that pours from the exhaust when accelerating. This vehicle is a hazard to drive and contacting Hyundai although this model and year is included in the engine recall, yields nothing but a pain as they have informed me, that my -??Vin-?? out of all of the other 2017 Hyundai Sonata-??s isn-??t included in the nationwide recall of my particular vehicle-??. Just my luck? I think not, Hyundai needs to acknowledge the multitude of hazards that they have manufactured and have out on road and properly offer assistance to these vehicle's owners to rectify this issue.

On cold mornings, during the first start of the day, and while going downhill, the internal combustion engine comes on while running on electrical power from the battery. This is understandably to heat up the engine to ideal temperatures. But within a minute, the car gives a hybrid battery error, fully loses power requiring to be stopped immediately. This is obviously dangerous anywhere but particularly downhill. The car requires to be restarted after pulling over 1-3 times until the engine / battery reach ideal temperatures. Then the car runs as expected. The dealership has been unable to diagnose the issue and chalked it up to an unrelated recall - which has been fixed, but the issue still occurs risking the safety of the people inside the car and around.

The engine lost power as driver was getting ready to go onto a major toll way, then when was able to regain a little power, was unable to go over 30mph. When was able to get to an independent repair shop to check it, engine knock code appeared, the check engine light only came on once the engine lost power, not prior to. The shop checked oil and the dipstick came out dry! They did not see any obvious leaks, and suggested it be towed to dealership. When towed to nearest dealership the car has been sitting for a week and a half and still not be looked at. The oil had been changed a few months prior and was not close to the miles needed for next change. This could have caused a fire for the car, it could have caused an accident if was not able to get to side of road. This is similar If not exactly the same that has happened to other Hyundai Sonata owners and is causing a lot of hardship for our family to be without this car or a loaner! This appears to be the recall on Hyundai engines that-??s happening to similar models.

While driving on surface streets (10-15 MPH) about 5 minutes out from our house, the accelerator stopped working properly and a warning popped up along the lines of "Hybrid HEV warning: Please shut off engine and restart." Since there were no other cars behind us, we were able to thankfully pull over without too much trouble. However, if we had been on a highway this would have been incredibly dangerous, as we would have lost speed quickly and had no safe way to pull over. There were no warnings prior to this happening on that day. The car just sudden stopped working and then lights popped on. Using an OBD reader, the issue code was P0DE7: Hybrid/EV Battery - Cell Voltage High. We are going to the dealer at the earliest appointment to have it looked at, and the car is clearly not safe for anything but surface roads with easy pull-offs. Related Items: A week or so ago, we had an incident where the car was a bit sluggish to accelerate after a right hand turn (e.g., needed to take foot off the gas, then put it back on after a moment to accelerate). However, no check engine light came on and the car ran fine after. A second potential related item was that the expected mileage on battery-only had reduced from about 27 to 23 miles on a full charge. This occurred within the last two months before this issue.

Bought the car in June -??21 and in Oct it started having engine problems (very low oil, shaky idle and hard transitioning gears) When I took to Hyundai Suntrup, 1 spark plug had bust and was covered in oil and dealership couldnt tell why. They replaced spark plug ran air induction service and sent me on my way. Come end of december and car was still having issues w low oil and shakey gear transitions so they gave me a upper engine cleaning service as well as an oil change. Now my oil pressure light keeps going off and I steadily burn through oil. At almost 2x the normal rate because when I last got the oil changed was only 1.5k miles ago.

I have a failing engine that excessively consumes oil at the rate of approximately 1qt per 500 miles. The notorious theta2 2.4ltr sonata engine has spewed so much oil into the top half of engine that it had infact so severely damaged the catalytic converter that it became a plug in the exhaust system. The oil consumption issue has destroyed the entire cars engine system and it was infact a ticking time bomb that Hyundai has denied multiple times to repair. After the catalytic converters reached 1700' and Hyundai indicated that it was fine nothing to worry about, we had to physically remove the catalytic converter packing and alow for the engine fumes to exit the car properly, they previously had mainly entering the passenger cabin or they were pushed back into the engine. I according to Hyundai have no warranty on the car, I owe money to my bank Hyundai and the dealership have been paid they have no problem letting me get stuck with a lemon. It's been to the dealership multiple times, campaign 953 engine knock sensor was done on 10/08/21 it has mysteriously found its way out of my car records. Tampering editing, falsifying documents are all illegal and wrong. Since the papers showed that it was done it should have extended the warranty to 10 yes/ 120,000 and I should be reimbursed for my rental fees for being unable to drive my car any distance thousandths of dollars into oil, not being able to get a safety inspection. missing multiple days of work, depreciation ( the dealership that sold me this car 18mo ago valued it at $17,000 09/20, and on 10/08 gave me a $6,000 trade in value) lastly a car in good running condition that is safe for us to use. HYUNDAI IS SELLING DEFECTIVE PRODUCTS AND GETTING AWAY WITH IT EVEN AFTER BEING TAKEN TO COURT AND HAVING MILLIONS OF DOLLARS IN FINES AND PAYOUTS. They are stealing from hard working family's that are already struggling to get by.
