It would be covered also stated if the engine light was flashing it would be covered or it isn’t the engine isn’t covered the inverter coolant is not bubbling or moving when car is on it is an inverter coolant issue that was a problem back when my first engine was repaired and should be covered I love my vehicle but I have had so many issues since getting it major things and the lighting system showing a black spot in my view as well that could not be fixed I will attach pictures of earning lights and video of coolant not circulating and the dealership filled the coolant way over the top I have to now take it back again to have it looked at.

2 Electrical System problem

Failure Date: 04/16/2024

Airbag light came on. Car is in otherwise perfect shape (red flag). Brought to Hyundai dealer. Was told it was a short somewhere on front passenger side. But it will cost $250 to figure out where. Then possibly over $1000 to fix it!! upon researching it I found many complaints on same issue on otherwise normal good condition Sonata’s. Clearly they used inferior components designed to fail. Similar to their stealable cars (with a usb cable) I’m sure you’re fermi liar with. They hid that until tic tok put out videos showing how to. They had to fix it due to owners auto insurance going up (way up). I can’t afford to repair this pressing safety issue. Hyundai should be held responsible for using knowingly faulty parts in their air bag system then charging customer large $ just to make an otherwise perfectly running car safe to operate. Oh, then they said they’d offer me a “loaner” till fixed. But their “loner” costs $50 per day!! that’s a rental not a loaner.

3 Electrical System problem

Failure Date: 03/02/2024

Everything was displayed in red on the front screen, it was automatically parked, and the steering wheel did not move. This happened late March/02/2024 last Saturday night, so I called aaa twice and had them toward to my house. March/04/2024 I called aaa on Monday and had my car toward to Hyundai service. They gave me a $199. 95 bill for finding the problem with my car. And they said they would contact me and let me know about the problem with my car in 3~4 days. I am an uber driver, but I am currently unable to work because I don't have a car.

4 Electrical System problem

Failure Date: 12/21/2023

The hybrid power system has stopped all together twice while driving once back in may 2021 and again in December 2022, the car has just under 50,000 miles. Both times this has happened the car was actively being driven, and has caused us to pull over on the side of the highway because there is no warning beforehand, everything from the power steering to the gas goes out. It’s terrifying and unsafe for anyone in the car but also near it when it happens.

5 Electrical System problem

Failure Date: 08/01/2023

Car was jerkikg yesterday and now it wont start.

6 Electrical System problem

Failure Date: 07/01/2023

Around the 70,000 to 80,000 mile range, I began to notice that I needed more frequent oil changes. Additionally, when making turns, the oil pressure light would illuminate. I reported these concerns to the service manager, steve purvis, at noblesville Hyundai, who advised that the light simply indicated the need for an oil change. Due to the ignorance of steve purvis, I took my vehicle to Hyundai of carmel, where the issue was not addressed until I reached 97,000 miles. During this time, the valve covers were replaced twice, yet there were no active leaks, and the problem persisted. Hyundai subsequently denied my request for an oil consumption test to further diagnose the issue. I then took my vehicle to a different shop, where a Mini oil consumption test revealed that my car burned over 2 quarts of oil from Friday to Monday. Additionally, my start/stop system has ceased functioning, preventing me from starting the vehicle. I have also noted that there are open recalls for Hyundai vehicles, yet my VIN is not recognized under these recalls. I have incurred significant expenses related to these ongoing issues. My safety has been put to risk because the oil can burn completely out and cause the car to break down in the middle of traffic like it has before. Hyundai dealership has confirmed the car has an oil burning issue, as well as an independent shop by the name of auto tech in indianapolis. Auto tech has also confirmed that the start/stop system is causing my car to not start. The oil pressure light is not consistent when my oil gets low. Some times it comes on, other times it does not.

7 Electrical System problem

Failure Date: 05/23/2023

The issue is unknown. On may 23,2023 I exited my car… maybe less than 10 minutes returned to car to go on with my day pressed the start button and it burst into flames.

8 Electrical System problem

Failure Date: 10/29/2022

I was traveling on a highway when a "hybrid system warning" suddenly appeared on the dashboard. Every dashboard warning light illuminated. The car began to lose power. I exited the highway immediately and the car began to have sporadic power and was "lurching. " I immediately pulled onto the shoulder and at that time another warning on the dash appeared within a minute or two of the first warning that said "shut engine off. " the computer screen began to flash on and of and the windows would not roll up smoothly. When the tow truck arrived the car wouldn't start and it didn't recognize the key fob. Hyundai now has the vehicle and claims the car needed a "software update", but they cannot tell me if it will ever happen again and cannot tell me why the car goes into critical failure when it needs a mere software update. This is the second time this has happened. The first time it was repaired under a voluntary recall campaign about a year ago. This is an extremely dangerous occurrence as the car loses power without warning. I was fortunate to be near an exit when it happened and able to safely get off the highway, but that was just luck. The manual indicates that a hybrid system warning means that the car can potentially go on fire.

9 Electrical System problem

Failure Date: 07/28/2022

My vehicle was stolen from in front of my home. The "alarm" did not sound or go off at all. The area where my key should enter was removed, vandalized, and then an iphone charger was used to start my car via a usb port that is located somewhere within that area. Apparently, this is a tictok trend that has been in the works for a while and targets Hyundais. Yet, there has been no response from Hyundai to recall Sonatas or elantras to remedy this issue. Now I am being forced to pay for repairs on a vehicle that was used for illegal activities and again have to place my family in. I do not feel safe in this situation and I am most likely privy to fall victim again until this issue is resolved.
