I am writing to report a concerning issue with my Hyundai Sonata 2016 regarding excessive oil consumption. Every 1000 miles, the vehicle requires approximately 1.5 quarts of oil, if not more. This rapid depletion of oil presents a significant safety risk for driving the car. Upon contacting the dealership regarding this matter, I was informed that they have no knowledge of such issues, which contradicts the numerous complaints I have read and heard from fellow Hyundai owners experiencing similar oil consumption problems. The dealership has suggested conducting an oil consumption test, which they advise will cost us a minimum of $280. However, it seems unfair to incur this expense for what appears to be a common manufacturing defect, particularly since our vehicle is no longer under warranty due to its mileage of 110,000 miles. I firmly believe that Hyundai should take responsibility for any related repair expenses arising from this issue. I urge you to address this matter promptly to ensure the safety and satisfaction of Hyundai customers. Thank you for your attention to this concern. I look forward to your prompt response and resolution.

The 2016 Hyundai Sonata 2.4L engine have an abnormal oil consumption, every 1,000 miles consume 1 quart of oil. After the discover of the issue, the car was took to Hyundai dealership for service and confirmed the car have an excessive oil consumption. They performed engine flush with additives to clean up the engine and see if the oil consumption diminished. An oil consumption test is currently in process to see if there are positive results. I read multiple articles about oil consumption issues and most of the cases Hyundai decide to replace the engine.

I was driving on the highway yesterday at 85mph when the engine light started flashing and the rpms went haywire. Then within 2 minutes of this taking place the car began to slow down and not want to go any further. I managed to get over to the shoulder of the road when the engine just shut off and would not restart. The engine drinks oil like crazy. We put oil in it every week and get frequent oil changes. On the day that it broke down on, I had been to the oil lube center that we do business with and had them top off all of my fluids. After looking into this problem online, it appears that there are many other people suffering with the same lemon of a car. Hyundai knows that there is a real problem with the 2016 Sonata, and they are not doing anything about it. We have spoken to the dealerships, and they say there's nothing they can do about the problem because it is out of warranty. We're still making payments on this vehicle and can't even drive it now. The mechanics said that the vehicle needs a new engine. Hyundai needs to issue a recall and help their customers instead of turning a blind eye to the problem. Driving at high speeds with absolutely no indication that there is a problem is a real danger. No indication lights had come on other that the flashing engine light and then within two minutes, dead on the side of the road.

Engine light appeared on my dashboard in late Feb 2024. At the same time, there was a noted fluid leak on my parking skirt so I immediately stopped driving it. On [xxx] I had car towed to mike's automative service station in South milwaukee, Wisconsin. He remedied the engine issue with 'leak stop'. on [xxx], I was traveling an [xxx] from milwaukee to oshkosh. Around half way, the engine light began flashing, the oil light was on and the car lost ability to accelerate. I engaged my hazard lights given I was in high traffic at that time and 'limped' car to the nearst gas station, to avoid being stranded on the highway. It was towed to a nearby location, richfield service center-richfield wi. Both the tow truck driver and the service station rep, sean, advised this oil-leaking engine business was a widespread and well-known manufacturer defect for this vehicle's make/model/year. They performed a brief diagnostic review and advised the engine would need full replacement to continue driving. I reported this incident to Hyundai's customer service online portal this day, too and have requested they replace the engine, given the mileage has not even reached 77,000 miles. I found no active recall or warranty on this vehicle but can prove I am the second owner, having inherited it from the original purchaser, the late [xxx] in 2016/2017 (unsure exact date). The vehicle is available for inspection at this time. I felt traumatized by this event, praying not to be run over on the highway while the car moved at a snail's pace and feeling terribly unsafe in pushing the car to the closest gas station. I felt everyone around me was in danger of not seeing me in time to stop or avoid collision with me. No official inspection has been completed by manufacturer, police, insurance or anyone besides the mechanics at the richfield service center locatio in richfield Wisconsin, on [xxx]. more detail not afforded in text space here.

I have a 2016 Hyundai Sonata that I purchased in 2021. The engine began "knocking" at 142,000 miles so I took it to dealership as it looked to be the same issue many of the Hyundais have been experiencing. I was then informed my claim was denied because a Service Campain from 2018 had not been performed. This is a known issue with these vehicles but my claim was denied over something outside of my control.

Background Info : On November 28th, 2023 I filed a case with Hyundai Consumer Affairs due to smoke and sparks coming from my 2016 HYUNDAI SONATA engine. I was assigned to a Case Coordinator Carla who did not provide her last name at telephone 714-694-4963. She was my contact person for the repair. I signed a tow authorization on November 28th, 2023 authorizing HMA to tow the vehicle to the nearest Hyundai dealership due to some delays in coordination on behalf on my contact Carla and the dealership Pohanka Hyundai received my vehicle on approximately December 4th, 2023. Per correspondence from Carla she had contacted the dealership with no response until the 18th of December 2023; approximately two weeks after the dealership received my vehicle. She informed me that she had made countless attempts to reach a service team member for follow up on an inspection. On December 18th 2023 I got in contact with Joseph to inquire as to what his inspection found. He stated -??That he did not see an oil leak and the car hand no oil.-?? I explained to him that was my car had been recently serviced at Jiffy Lube on August 1st 2023 at 44,664 miles for an oil change. Per Hyundai the oil should be changed every 3,000 to 5000 miles which I had not exceeded as my car had 46863 miles at the initial time of the service inspection that he performed. He then said -??Jiffy lube did not put any oil in the car then-?? which was impossible. I made contact with the Jiffy Lube location who performed the oil change to get the record of my last oil change as Joseph had a differing opinion. I was informed that in fact the oil was changed and they could provide video proof if necessary. I then communicated this information to Joseph as well as provided a copy of the last oil change. I then was told that I needed a CVVT replacement, transmission flush and oil change. I attempted to address his initial diagnose of -??no oil in the car-?? as I had proof that it had been changed and that they should do furthe

My vehicle has been consuming oil very often. I have done regular maintenance on it since I purchased the vehicle. I first noticed the issue in August of last year. My remaining oil in my engine before an oil change would be little to none. I brought it to a Hyundai Dealership and they told me they can do nothing. They told me if my check engine light came on and my engine seized, to call them. I had a check engine light of O2 sensors being out. I replaced those. My engine continued to consume oil. I had another check engine light come on last week and it was my timing sensors. They went out. I replaced those and my technician looked inside my engine, and it is filled with metal shavings. My timing chains will go off if I drive my vehicle and my engine will no longer function. Hyundai in Sioux Falls, South Dakota told me numerous times they did not see why my engine was consuming oil. They also told me they would have a tow truck come get my car to repair if it was seized or damaged. They refused to last week. They told me the only way to fix my engine is if the code of P1326 was present. My code now is P001000. I am stuck without a car because i cannot drive mine.

While driving the car a noise came from the engine and I lost acceleration and then the car just died in the middle of busy traffic. The car was stuck in busy traffic till it could be towed since it wouldn't restart. After doing research it is a known problem with Hyundai and Kia engines and there are thousands of people like me and Hyundai refuses to take responsibility and puts the blame on the consumer stating they didn't maintain the vehicle. I could of been seriously injured by this and a lot of others are in jeopardy with these faulty engines.

My car was burning through oil fairly quickly. I had to refill my oil in between oil changes. I was also getting oil changes about every 2k miles until I realized it was not normal. I contacted Hyundai about an oil consumption test on December 19th. I did not hear back until almost 2 weeks. The email did not ask me what I needed but basically said-?? you-??ve talked to someone if you need something let us know-?? I had called in to check the status. Not sure why they thought this was resolved. About a week later my engine failed. Hyundai will not fix my engine because it does not fall under warranty. From what the mechanic told me, my car has carbon build up due to the burning oil which caused my cylinders to crack. I don-??t know much about cars but oil is not suppose to burn that fast.

On the way home after I purchasing my son his 2016 Hyundai sonata limited, he noticed his oil light come on and he stopped to check his oil and it was almost empty. He got an oil change and called the dealer and they told us that it was probably the oil change place that didn-??t tighten the drain cap. We took it to them and they said no issues with the cap. Went back to Hyundai and when you open the hood the engine is shiny and coated in oil. They would not do anything for us, the car was at 117k and they told us to drive it till it knocks and fill it and maybe Hyundai would replace engine. Hyundai did not warranty this cars engine. He has had his car now for 5 months and puts over a gallon of oil in it a month. It started misfiring, so we replace his spark plugs and noticed oil all over the spark plug number 2. This was a one owner car, that showed she took good care of it, and that is why we purchased it. We are stuck with this car and it is not safe and my son is 19.

Engine began misfiring, spark plug coated in oil which indicates piston ring defect. I get regular scheduled maintenance, often needing oil far before maintenance would be due. This is a KNOWN issue and Hyundai is NOT TAKING RESPONSIBILITY.
