POWER TRAIN
I came to a stoplight and then tried to go forward and it got to about 20 miles an hour and this horrible knock happened and when I pushed on the gas it just whines I haven't had the money to get it somewhere to be looked at but I'm thinking it's the transmission but when it made that knocking sound it sounded like the whole engine fell out of it and I was in heavy traffic at the time.. you can drive it no problem up until you get 20 miles an hour and then it makes that horrible knocking sound

ENGINE, FUEL/PROPULSION SYSTEM, VEHICLE SPEED CONTROL
I was commuting home from work when suddenly there was smoke coming from under the hood and the vehicle completely stopped working in the middle of the road. It would not accelerate and I had to get help to move it into a parking lot. I had to get it towed to my home. The car will not start. If we turn the key to try to start it, the engine starts smoking.

ENGINE, ELECTRICAL SYSTEM, UNKNOWN OR OTHER
First off there was no lights on other than the low tire pressure symbol that shows up, so I decided to go have my tire replaced, got it done, I drove off after having a tire replaced and within a minute or 2 of being back on the road my car just shuts off. I pulls over to see or access the car, don’t know what happened. I ended up having to have the car towed home.

ENGINE
I have had the same issue 3 separate times related to the coolant system. The first time happened January 2021. I was driving on the highway and I noticed that when the car switched from electric to fuel a large plume of white smoke came out of the exhaust and then the engine overheating message started. I checked the coolant tank and it was completely empty. I managed to get some coolant in the car and get to my destination. I checked the coolant tank again and all the coolant that had been put in was gone. I immediately had the car towed to the dealer. They found the issue was a leak near the muffler and eventually replaced that and other gaskets. In May 2022, I noticed again that when I switched from battery to fuel on acceleration that there was a plume of smoke coming out of the exhaust and my coolant was very low. Brought to the dealer and they confirmed again there was a leak but this time with the EGR cooler and associated parts. In December 2022, I had just gotten an oil change from the dealer and they gave me a clean check up. The next evening I was on the highway again and I received the engine overheating message. I was able to get to the dealer the next morning after refilling the coolant twice. I provided them with the previous paperwork from the other two fixes. They confirmed again that the leak was happening with the muffler so they replaced more parts. In all I have for over 3 months fixing the same issue. I posted on Reddit to see if others have had the same issue and slowly more and more people with the same model year or the year after are reporting the same problems as seen https://www.reddit.com/r/Hyundai/comments/uhx7lf/coolant_leak_through_exhaust_on_2020_sonata_hybrid/?utm_source=share&utm_medium=web2x&context=3 Every time it's happened it's been covered under warranty but my concern is that it happens outside of the warranty and I will be on the hook for an expensive repair or forced to a new vehicle.

ENGINE
Purchased car with just under 97000 miles. Was working terrific. Time for the first oil change and 2 miles after the change the car froze and went limp. Traveling 45 miles per hour it recorded a trouble code on my monitoring device. P0605 - ROM error and the car was dead. All lights had lit up on the panel and then it was off. Luckily was able to recover to the side and turn into a parking lot. Oil was low the night before and refiled before oil change. An additional code was recorded on Feb 12 P0128 Coolant Thermostat Malfunction. The selling dealer cleared the code and said the car was fine. I think there may be an additional issue here and why the oil was low.

EXTERIOR LIGHTING, ELECTRICAL SYSTEM
The electrical system of the vehicle malfunctions regularly. When the headlights are on, the brake lights are stuck on and do not turn off, nor do they properly "activate" when braking. If the headlights are off, they work just fine. If the headlights are on, the entire dashboard lighting is prone to going haywire. On several occasions with the headlights on, the electrical system has malfunctioned and turned off all lights, inside and outside. They will not turn back on unless I turn the headlights off and back on. Turning on the high beams has made the lighting malfunction and the entire vehicle will decelerate, even when pressing on the gas. I will gladly allow my vehicle for inspection upon request. This is clearly a hazard to both myself and other vehicles on the road, especially at night. Not only is the lack of functional brake lights a hazard, but so is having rapidly flashing lights on the dashboard to myself as a driver. Moreover, the headlights randomly turning off at night is extremely dangerous, as is the random deceleration. Upon looking into it to see if I could find an answer, I learned it's a common problem with 2011-2014 Hyundai Sonatas and to see that so many have this issue but nothing has been done to correct it is shocking. My local dealership did inspect my car upon an engine seizure a few years ago, but all they reported was an issue with the passenger side brake light bracket and bulb (another common issue it seems). I have never received any sort of warning lamp or message, aside from the traction light randomly coming on from time to time for no reason.

ENGINE
The engine is consuming (burning) the engine oil at a excessive rate. Engine oil has to be added almost every 1000 miles. Talked to multiple mechanics and learnt that it is a common problem with Hyundai. Constantly checking the oil level and topping off is not what we expected when I bought the car.

FUEL/PROPULSION SYSTEM
Everytime I put fuel in my car I get a strong gas smell outside and inside my car. I’ve looked to see if there is a leak and do not see anything. Looked to see if there are recalls and shows there are 8 but when I put vin in. There is no recalls. Don’t know if the have been taken care of alright or I never had them on my car.

AIR BAGS, ELECTRICAL SYSTEM, VEHICLE SPEED CONTROL
The airbag light is on, indicating that the airbox is not operating and will not go off in case of an accident. All steering wheel controls also don't work so it's impossible to adjust settings using the steering wheel or to enter cruise control at all. Previous years of this same vehicle had clock spring recalls and this appears to be the same problem so I wonder if the other recalls should be extended to this year vehicle? thanks

EXTERIOR LIGHTING
As stated by other owners the brake lights come on and off I have had the bulb replaced several times. I wiggle the blub it comes on and off. This is a danger to cars behind me as the brakes lights are not working properly I believe there should be a recall as many owners are having and have had the same issue with this problem. My sister has a Hyundai not a Sonata had the same issue but her type of Hyundai was recalled for fault wiring. The Sonatas should be recalled also.

ENGINE, FUEL/PROPULSION SYSTEM
I have a used 2015 Hyundai Sonata that I purchased from a Hyundai dealership in December 2021 (due to the chip shortage, I had to purchase used). A few months later In June 2022 I was driving on the freeway and my car felt like it was losing acceleration. I was already planning to exit the next exit to go to my destination and as I was exiting and came to stop at the red light before I could then turn right .. my car started to violently shake. Ultimately, after going to my own car place the following day and them determining that the fuel injectors and the computer were not talking, I had it towed to Hyundai where after another 4 days they also determined it was that problem and they replaced the computer under warranty. Well today I was again on the toll road / freeway and I was in the fast lane, I suddenly felt a strong jolt and my malfunction light came on and it was blinking on the dash, I knew not to drive it based on the light and as I steered to the right shoulder to slow / stop and call AAA I could feel my car just lightly shaking again. My car is now at the same Hyundai dealership where I purchased it and I’m waiting for diagnostics on the problem. Before this all happened, the first time in 2022 I was having sporadic issues with pressing the start button and there was a bit of a delayed start at times, even after the computer was replaced I’ve still had hiccups with the start button at times but it’s been very sporadic and it has never been a starter issue (had my car place already check that). So I’m now waiting to hear if the computer indeed failed for a second time. They cannot assess my car until Monday or Tuesday at the dealership (today was a Friday, my car was towed there at about 11am today). If the computer did fail again, it lasted about 14,000 miles before it just died again. Quite frustrated at the moment. I already contacted Hyundai corporate and opened a second case today regarding all of this.
