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.

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.

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.

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.

Express oil has stated this is not normal and a cause for concern. There are no warning signs for this problem. Only awareness from the performance of the cars decline to run properly.

When driving at 65+ mph the "Turn off Engine - Check Hybrid System" flashing triangle warning lamp came on, causing me to pull over on a freeway putting myself in danger of collision. After turning off vehicle with no explanation of warning symbol in owners manual I turned vehicle on again after 5 minutes and warning lamp re-illuminated. After waiting 30mins while still on shoulder of major freeway, I reignited engine and warning lamp had disappeared so I drove vehicle home (less than 5miles) and took to Hyundai service dealer the next day and they determined the coolant (water) pump and thermometer needed to be replaced and it was a known issue covered under 100k warranty. My vehicle was at approximately 102,700 miles and I paid for replacement of coolant pump and thermometer out of pocket.

I purchased my car used in December 2021 it is a 2016 with 97k miles. 2 weeks after I purchased the car I called to set up service because my cars engine was making horrible sounds. with me putting less than 900 miles on the car (it took 2 weeks to get it in for service) I had a in near perfect condition car with a blown engine. The car still runs and drives fine but it is using almost a qt of oil a week. The dealer is Autonation Hyundai of North Richland Hills, Tx knows the history that these engines are junk. But rather than be stuck with this issue they told me my valve covers were leaking and that was my issue. Keep in mind I have no oil leaking from anywhere and not a drop is on my car or on the ground. This car has an oil consumption problem along with thousands of other Hyundais and neither Autonation or Hyundai are willing to do anything about it because I am the second owner even though I bought the car in this condition from the dealer. The engine is failing because it is consuming oil. The engine is making noises and could at any time while driving could lock up and cause a dangerous situation on the roadways. This is a very well known issue and even a current class action lawsuit. The dealer is refusing to inspect the vehicle because I am the second owner and have no warranty. The only sign is low oil. The car is using oil at a rapid pace and I have to check and add oil weekly. This is a 5 year old car with 100k mikes on it.

Complete engine failure engine failed in 2021, prior to recall notices (2 of them) finally had it towed to hundai. Hundai wants me to buy a new engine block for $13,000 thirteen thousand dollars. Hundai needs to buy that car back, or pay to put a new engine block in it. Had the parts not been faulty, I'd still have a car to drive.
