Hello. I'd like to report an engine oil consumption problem. I owe Hyundai sonata 2015, 9 years and 5 months. I have been having engine oil consumption problem over 2 years. It was not that serious around 2023 and 2024, also I know this car has oil consumption problem, so I checked engine oil frequently and refilled it when level went down below the "L" level. Last week, I had an engine alarm whish was powertrain system problem " P2096". So I brought my car to Jeff's garage(180milles from my home) and fixed this problem. When I checked the amount of oil before I drove, level of oil was a little above "L" level. But, when the technician checked the car, they found that engine oil left 1 quart only. (I refilled the oil 4 times already for last 4 month, I drove around 2300 miles for last 4 month) They also showed me the stick without any engine oil. They changed new oil and made sure the level on the stick was above "F" level. However, after I drove around 180 miles, I found the level was between F and L. There is no oil leaking but oil consumption is getting worse. I think some of oil consumption is normal or expected, but this is too much. Please check the safety of this engine.

Car has been burning oil since September of 2024. It’s burning 2 quarts of oil every 500 miles. The oil is burning out spark plugs and coils every 3 months. These engines need to be recall and Hyundai needs to be held accountable.

When I bought the car from Mathews in Marion Ohio the car looked like it was already in some form of accident due to a previous owner and I was unaware what caused the accident or any other problems with the vehicle upon buying. I was not presented with a carfax. I have electrical tape at the bottom of my bumper and there’s a problem with acceleration. It accelerates by itself and veers right when I take my hand off the wheel. I’m afraid to drive my car on the highway. I have complained about this problem to Mathews twice. I am now in a loaner until they figure out what’s going on.

Car does not when temperature drops below 30 degrees (Fahrenheit) even when garaged so you cannot drive car and u have to be towed several times at night. Local dealer stated unaware of issues but there is forum of Hyundai owners who have this problem with 2018 sonata. A local mechanic studied issue and did replacement on the relay switch and starter and now car starts in cold weather. It took me four years is stress and I put in complaint to Hyundai and they did nothing to compensate me for parts. This is a very big issue to be somewhere called late at night and not have reliable transportation.

Dashboard has large cracks all over it including where the passenger air bag is located. I am concerned about the pieces of plastic flying if the air bag deploys. Also concerned that the cracks could release the air bag at any time, even during normal driving. Dealer only suggested getting a dashboard cover, but that would negate the purpose of the air bag. My research showed that there are many other cases of the happening with Hyundai Sonata's 2011-2014.

In 8-2021 the original engine locked up due to a crankshaft bearing lock up. The dealer replaced the entire engine with a rebuilt. It locked up within 10 seconds after I drove from the dealer due to a massive external oil leak from the engine front area. The dealer could not determine where the leak was coming from and prepared a report to reflect this. The dealer then replaced this first replaced engine with another rebuilt engine. I drove it and within 5 minutes of driving the radiator plastic side tank exploded open and lost coolant. The engine then misfired and began to smoke out the tailpipe. and engine areas. The dealer demanded I pay $1,100 for a replacement radiator and then they would confirm that the head gasket was leaking from the combustion chamber into the cooling system that exploded the radiator side tank due to overpressurization from exhaust gas. Another dealer saw that the combustion gas had a large leak that was coming out of the broken radiator plastic side tank and advised repalcing the engine with another engine and radiator. The engine locked up while driving it as a result of overheating and/or coolant inside the cylinder that has the head gasket leak. The dealer and factory refuses to repair the engine that is still under two different kinds of warranties. The warranties expire on 10-12-2025

ENGINE, FUEL/PROPULSION SYSTEM
I was driving a 2016 Hyundai Sonata on a mountain highway and it started to run rough and lose power dramatically when accelerating. A dangerous situation on a steep curvy highway that has many one lane sections. Shortly thereafter a dash light came on. There was no warnings or dash lights or symptoms prior to this incident. I took the vehicle to a mechanic and ran the code. It said there was a misfire in cylinder 3. Replaced the ignition coil and spark plug for cylinder 3 and it did not fix the problem. The mechanic then pulled the motor to check the valves. Valve 3 was burnt, had a hole and stuck open. The car had approximately 75,180 miles. Well within the warranty time frame of 10yrs or 100,000 miles for an original purchaser. The mechanic had the valve machined, and replaced the head gasket and reassembled the the motor. I picked the car up and drove it home. Within 3 days I noticed an oil leak under neath the car where the engine bay is. I took the car back to the mechanic and he diagnosed a hairline crack in the oil pan. After some research I came across a letter from NHTSA on a defect investigation of Hyundai/Kia oil drain pan assemblies. This is exactly what happened to my car! I have paid 3500.00 to fix a car that has less than 76,000 miles. Hyundai needs to do better.

VISIBILITY/WIPER, ELECTRICAL SYSTEM
I am experiencing an electrical malfunction with the driver-side door controls and side mirrors on my 2022 Hyundai Sonata Limited. The buttons on the driver’s door panel intermittently stop responding, and the lights on the panel flicker. At the same time, the side mirrors move up and down randomly, without any input from me. This issue occurs while the vehicle is both stationary and in motion. This malfunction affects the visibility and safe operation of the vehicle, as it can disrupt mirror adjustments while driving. I am concerned that this could be a potential safety hazard, especially at night or in high-traffic situations. I have researched online and found that other Hyundai owners have reported similar electrical issues with door controls and mirrors in recent models. I would like the NHTSA to investigate whether this is a widespread issue and determine if Hyundai needs to issue a recall or a technical service bulletin (TSB) to address this safety concern.
