FUEL/PROPULSION SYSTEM
I have a 2020 Hyundai Sonata SEL Plus. For the past month I been dealing with my CEL regarding Fuel Tank Pressure sensor and I end up replacing one from hyundai itself. After doing that I notice my fuel tank has expanded and I’m currently dealing with Hyundai & the dealership to see if they can make a recall regarding this issue or just fix it period since it’s a big safety concern. This been happening since mid April. My back seat lifts up from time to time and my fuel pump cover is bent. Below I’ll add some pictures so you guys can see how my tank straps are actually bent which is very uncommon for it to happen. I recently took it to the dealer last week after reaching out to hyundai corporate and they took pictures and send it for prior approval to see if hyundai is willing to replace this. I can’t fill up my gas tank, I constantly have to out between $15-$25 the most due to fuel mileage issue since the tank has expanded I get fuel mileage inconsistency

ENGINE
While driving on the highway the car stopped .. it was towed to Hyundai as it is still under warranty and ultimately we were told it suffered "catastrophic engine failure" I was also told that a new engine would not be covered. When I asked why I was instructed to give maintenance records which I did. It was denied BEFORE they asked for records. I have been going back and forth with Hyundai and the reason they have given me is an exact effect of their ongoing issues with the THETA II- GDI engine. I have compiled so much research regarding the defect and Hyundai stopped responding to me when I asked them the difference between my car's engine and those that Hyundai knowing delayed recalling and the thousands of same engines that have determined as defective. This has been going on for months and I am not going to let it go and there is a growing petition for another investigation to be opened. Hyundai deliberately delayed recalling a known defect that has affected thousands of vehicles and it is shameful they are playing games. I have an enormous file of data that would indicate the 2017 Sonata Theta II is just as defective as all the others and that their own mechanics have gone on the record admitting that an oil blockage from metal shavings will ultimately cause a catastrophic failure. I have emails from Hyundai and Texts from dealer on cost. I am checking with my attorney to see if they can be shared.

SERVICE BRAKES
The car has been meticulously maintained — I am glad to provide all records of regular service upon request — and lovingly cared for. It came to us in great shape. Until, that is, I drove it for the first time and the brakes failed. I rolled into an intersection. Luckily, there was no traffic and no one was harmed. But I had a very helpless feeling, and I feel incredibly grateful no one was hurt. After taking the vehicle to two mechanics, they independently confirmed that a sensor in the ABS module was failing, leading to a sudden loss of braking. After a cursory internet search, I found that many owners of this model and year of vehicle have encountered this dangerous problem.

ENGINE, AIR BAGS
Airbag clock springs module malfunction disabling emergency deployment of the driver’s side airbag in the event of a collision. My 2012 Hyundai Sonata 2.0 Turbo with 93,336 miles on it, ending seized up going at highway speed causing instant and complete loss of power. Smoke started coming out from under the front engine compartment hood making me think the car was on fire. Trying to get the car manuvered off the highway and over to the right side of the road I was almost involved in a collision with other traffic. I was scared almost to death. Hyundai Motor America is now refusing to repair my vehicle even though it is covered under their extend warranty.

SERVICE BRAKES, ELECTRICAL SYSTEM, ENGINE
In April 2023, I purchased a 2015 Hyundai Sonata Eco from Carvana with 56,000 miles. By May 2023, the mileage was around 72,000. While driving from South Houston to North Houston on [XXX], 2023, the car loudly popped as I exited the highway around 5:00 pm CST. I noticed smoke coming from the rear and parked in a construction zone near a convenience store. Upon inspection, the vehicle stopped working, and I saw a significant fluid leak underneath. A bystander alerted me to flames from the bottom and under the hood. I called 911, and the fire department arrived to extinguish the fire. Fortunately, there were no injuries or property damage. I later discovered that specific 2011–2015 Hyundai models had been recalled due to fire risk (NHTSA ID: 23V-651000), but this did not include the Hyundai Sonata Eco. The recall was due to the anti-lock brake system (ABS) module leaking brake fluid internally, potentially causing an electrical short and leading to a fire. I have photos and videos documenting the incident. Following the incident, I filed a claim with Travelers Insurance, and on May 28th, 2023, the vehicle was declared a total loss. While I appreciate their offer of ~$13,000, it is insufficient to cover the remaining loan balance of approximately $17,300. I am worried about the financial impact and potential danger I face due to this malfunction. The lack of information highlights the need for better consumer education. I am now looking into options to cover the remaining loan balance, acquire a new vehicle, and, most importantly, advocate for improved driver education regarding this defect.

STRUCTURE:BODY
The cap on the shark fin antenna came loose in normal service and cannot be secured. If this part were to fly off at highway speeds it would pose a safety issue to following vehicles since it becomes a projectile capable of causing significant damage. This problem is similar to that documented in KIA TSB SA272 which Hyundai does not recognize, although both manufacturers share similar component designs.

SEATS, FUEL/PROPULSION SYSTEM, UNKNOWN OR OTHER
An independent service center advise us that the gas tank had expanded which could have put my family at risk if exploding or catched on fired. This happend on June 15th 2024 while driving, a sudden explosion coming from the back of the car was heard. Little after the explosion like sound we perceived as if air was coming through the back as if we had a window rolled down. When pulled to check, i notice that the back seat was popped up. No warning on the car was giving prior to the incident. Will take car to Hyundai dealership to have it inspect by them and have a solution.

ENGINE, STEERING, FUEL/PROPULSION SYSTEM
On two separate occasions, one at @9500 miles and the next at @19,000 miles the car engine started shaking and lost all power while driving. Unable to steer car. Both times towed to dealer and they say it needs new spark plugs and need to clean cylinders. They do not know root cause of problem and have not done any testing of the engine, no leak/compression testing. Dealer refuses to cover cost of repairs saying out of warranty but cannot give any assurances this won’t happen again. I’ve requested they contact Hyundai engineers to find out what’s causing this and, to date, they’ve done nothing. Vehicle is unsafe to drive and is still at dealership with no reason to underlying issue.

STEERING
Complete steering column replacement is required (COLUMN & SHAFT ASSY-STEERING 56310-C2700). When turning all the way, like to turn 90 degrees or enter a parking space, the steering wheel locks. Car must be turned off and restarted. Sometimes you have to do this a couple of times for the steering wheel to unlock. Hyundai dealer agrees that the steering column has to be replace, unsafe to drive vehicle. It is June and have been waiting six months for Hyundai to provide the part. Hyundai USA corporate says they don't know when the part will be available, they will not provide a date, could be next year according to some employees at the Hyundai dealer. Hyundai says it is not a manufacturing defect, even though there are many comments on line, and previous models have issued recalls for this same defect.
