Oil Consumption Test Failed, I was originally told if I could prove it was burning oil and not leaking then I would receive a new engine. New engine rejected saying Hyundai no longer warranty engines for that reason. Was told that when motor seized to have it reevaluated for bearing or rod failure. No way to determine bearing or rod was cause of oil consumption without tearing the motor apart. Knocking noise from engine and experienced Engine Failure, resulted in being stranded in middle of highway with my kids 1 yr after oil consumption test. Hyundai rejecting engine replacement due to low compression from cylinders. Not willing to honor their warranty after an obvious lemon of a motor.

My 2016 Hyundai sonata is burning a lot of oil. I have to constantly put more oil in it. I went to the dealership and they said there is an engine recall to replace the engine but I have to wait until it fails. I don't want to be on the road and my engine seize up and an accident to happen. They said they can't do anything until something happens. That sounds extremely dangerous

The 2016 hyundai sonata keeps losing oil within about 500-800 miles after changing the oil the dipstick shows that the oil needs filled. I have never had to refill the oil so quick after changing on any car I have had. I ended up adding an additive to seal whatever leak or malfunction that the sonata has. I have looked it up and my car does not seam to be the only one with this issue. I never know when its gonna be too low and hurt my engine.

My vehicle first went into limp mode and stalled while driving December 2021. Vehicle was taken to Dealership in Alpharetta, GA. I was advised the knock sensor needed an update. The update was completed but the vehicle continued to go in limp mode and stall again March 2022 after driving less than 1000 miles since previous repair. The vehicle was taken to dealership in Wake Forest, NC. This time there was no update for the knock sensor so I was advised they would need to replace knock sensor but it was on backorder until end of May 2022. The knock senor was replaced picked up vehicle and engine light came on by the time I had drove 50 miles and vehicle started to go in limp mode and stall again and car started shaking an bad vibration. Drove the car next morning and it put me down again going into limp mode, stalling, whole dash board lit up every warning light on and dinging, car shaking and made loud noise had to have towed back to dealership. This time dealership claim it came from misfire on cylinder 3 but that doesn't explain all the issues. I was called to pick up car again June 2022 car had bad vibration, knocking, still going into limp and stall mode, hybrid system warning light came on again, gear sticking not changing like it's supposed to had towed back to dealership. This time dealership replaced other 3 cylinders picked up car July 2022. Did a test drive advised car is still stalling, gear still sticking, vibration still, air not cooling and hybrid indicator needle bouncing back and forth from power to 80 never stabilized. Dealership claims can't find anything wrong. I have almost been hit 10 times since December 2021 because of vehicle going into limp mode while driving this is very dangerous to be going 55 to 70 and vehicle drops speed back to 10 all of a sudden in traffic

I tried numerous times last year to get my car into the Beaverton Hyundai dealership to address the engine recall each time the service date they would call and cancel due to lack of proper equipment to diagnose. July 19th the vehicle was at the Nampa Hyundai dealership service department for the open recalls. I informed the service department of the loss of power I was experiencing and that no warning lights had come on. Upon completion they stated the engine passed and the smartbox was replaced and car passed the 32 point inspection. On July 22nd the car suffered complete engine failure and had to be towed to the dealership on July 23rd the car was then transferred to the Boise dealership on the 28th on the 29th I was informed they couldn-??t diagnose in Nampa that-??s why Boise was going to try. On Monday August 1st the service department notified me that there was not enough amps in the battery to diagnose and wants me to pay $275 plus tax for a new battery to diagnose. I have been stranded over 400 miles from my home for one because of engine failure they never offered a loaner they have had the car for over a week with no answers! The car suffered complete engine failure on July 22nd so why are they asking me to pay for a new battery on August 1st to diagnose? I truly feel they are avoiding replacing the engine and trying to charge me for something I never had an issue with until the engine failure. I am out a lot of time and money over this issue and I-??m disabled this has completely devastated my well being as well as my health due to being 400 miles away from home and needing additional medical care. I want Hyundai to be held accountable for the recall repairs and provide temporary transportation while it-??s being addressed.

The car requires a quart of oil every 1 to two weeks. Brought it to multiple dealerships and was never given a reason why. Car was making knocking noises anytime driven at 45 or below and sometimes higher. We believe it had to be about the recall Hyundai has advised us about multiple times. We brought it to them on Friday July 22nd. They updated the Hybrid system and we left. Driving the car to work July 27th and the car went into -??limp-?? mode and stated that there was a issue with the hybrid engine and to shut the car off immediately. I was able to pull the car off the road and turn it off. The engine light constantly blinked when the error happened. When I shut the car off and turned it back on, it the same hybrid error shows up on the screen again. We had to have it towed to the same dealership we went to the previous day. They have to diagnose the issue but it might take weeks because they have one hybrid tech.

On Thursday June 30th my 2016 Hyundai Sonata started jerking and stopped on me. The check engine light or any of the warning lights did not come on to warn me of any issues on any of the previous days. Since i was at Wal Mart I was able to get it pushed into the service center. The service techs there said that there was no oil in the car and only sludge came out. They changed the oil and I was able to get the car home. The car shook violently as I drove it but I was still able to get it home. Once I was home I lifted the hood to check the engine and noticed the engine covered in oil.I immediately called the dealership and they asked me to call Hyundai Consumer Affairs as oil consumption was a known issue with the Hyundai Sonata. The consumer affairs agent gave me a case number. I had the car towed to Vandegriff Hyundai in Arlington, TX on that same day and waited for a phone call. On 7/18/2022 I was contacted by Hyundai Consumer Affairs and told that the car has two issues. The first issue was that the car was misfiring and the second issue is that the car was burning oil. They told me that I would have to pay out of pocket for new spark plugs and a new coil and that the issue with the car misfiring would be fixed after that. They also told me that I would still have the issue with the car consuming oil and that I would have to pay out of pocket to get the carburetor flushed and cleaned. They also stated that it was not a guarantee that whole motor would be an issue after that. This is a safety issue because the car could have stopped in an unsafe area, on a train track or in heavy traffic where other cars could have slammed into my car as there was no warning or check engine light that told me that the motor would stop abruptly like it did that day.

July 16 2022 I was driving with my family (wife and kid) about 65 MPH on 91 Fwy around 9:00 A.M. lane #2 - my 2016 Hyundai Sonata started to shake and ultimately engine shut down middle freeway - many cars driving behind me was trying to dodge my car to my left and to my right - avoiding hitting my stall car -it was scaring things ever happen to me and family. Subsequently doing researching about my vehicle - I found out the car had problems with the engine and many recall items related engine problems. I never received any information (email, letters & text) about any recalls or issue regarding my 2016 Hyundai Sonata since I bought the vehicle used from the Hyundai dealership in 1307 Kettering Dr. Ontario CA 91761. My vehicle now is in another Hyundai dealership sevice shop being evaluated for engine problems. Getting alot run around from this Hyundai dealership (9898 Trask Ave. Garden Grove CA). Waiting around for two hours No one seem to care or wants to take any responsibility. Service reps already asking me money to do vehicle inspection ($500) and service for new engine. Everything is about financial gain. If I knew what Hyundai Corporation is doing - I should never buy a Hyundai Hyundai is risking my life for financial gain. I email Hyundai Corporation about my car and concerns. Currently waiting for response.
