The fuel tank assembly became pressurized with compressed air due top worn purge control system check valve. This caused the tank to deform and the deformation of the tank led to the fuel pump being pushed out and the back seat of the car was completely unattached and no longer secured. There was a strong presence of gas smell in the car as well. The check engine light came on and the car began to drive poorly. It was taken directly to a Hyundai dealership where it remains as of today. This could have resulted in the car catching on fire and potentially killing everyone in the car. My [XXX] daughter and 2 friends was driving the car from Louisiana to Mississippi when this occurred. The dealership in MS told her she needed to call and find someone to come and get her because the car was not safe to drive. My daughter was stranded in another state and had a college friend come and get them since I did not have a car and I was in Louisiana. After several hours her friend was able to pick them up which she remained stranded in MS for an additional 4 days. I had to get a friend to meet them halfway and bring her home because the dealership said there was nothing they could do to assist with transportation. This occurred on [XXX]. My car remains at this dealership in MS with only the testing to say the gas tank test failed and the car could not be driven. I was told Hyundai would offer a buyback on my vehicle because the repair was costly and time consuming. I have not been reimbursed for my transportation expenses through Uber as of today. I was told I could rent a car and they would reimburse my expense after I submitted a receipt and waited several weeks to process and then at least 2 weeks for the payment to clear. Either way I have received nothing. There was not any warning and the dash lights and poor engine running all happened at once. She drove straight to the dealership on [XXX]. We have not been treated fairly with this situation. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S

2022 Hyundai Sonata N Line, VIN [XXX] , purchased August 15, 2025 with low mileage under original manufacturer warranty. Within 3 months, recurring transmission and drivability failures began. Six repair visits since November 2025; 71+ cumulative days out of service within 8 months. Visit 1 (11/24/25, 14,748 mi): Hesitation/failure to accelerate from stop. Could not duplicate. Visit 2 (12/4/25, 14,800 mi): Same concern. Fault codes found; auxiliary pump and relay replaced. Visit 3 (1/19/26, 15,982 mi): Check engine light, jerking. External oil pump leaking; replacement required. Visit 4 (1/30/26, 16,025 mi): Check engine light. TCU update, DCT learning performed; declared resolved. Visit 5 (2/19/26, 16,119 mi): Check engine light returned. Transmission oil pump failed; replaced. Visit 6 (4/14/26, 16,945 mi — OPEN 44+ days): Post-repair lurching, infotainment failure, ongoing jerking. On 5/28/26, the service manager at McDonough Hyundai (McDonough, GA) stated the vehicle likely requires a complete transmission replacement and disclosed approximately 4 additional vehicles at the same dealership with identical unresolved issues. Hyundai Motor America refuses to authorize repairs or Techline escalation unless the dealership confirms the intermittent concern — a structural barrier that prevents warranty resolution. Safety concern: repeated failure to accelerate normally from a stop creates direct risk of rear-end collision or inability to clear intersections.

In November of 2024, I had a Check Engine Light for a Cylinder 2 misfire and a fuel to air mixture ratio. Had it towed to a Hyundai Dealership. Got a call the next day saying it was fixed. Picked the car up and 50 miles later it popped back up. Had it towed back again. They said my fuel injector was cracked. They had to order the fuel injector directly from Korea. Took 5 days to get the part and it installed. Fast forward to September 2025, Cylinder 2 misfire showed up again(same cylinder the fuel injector was replaced) and now the car shakes violently when accelerating and stalled at a stop light. Massive safety concern due to risk of an accident. Car to be towed to another dealership for the same issue less than a year apart.

Fuel Lines and Connections / Fuel Tank Band / Fuel Tank Vapor Vent System Hoses [XXX]: My check engine light illuminated. I immediately returned to Hyundai Riverdale. They advised me it could be the fuel tank and stated they needed to keep the car for 5-7 business days. May 1, 2025: I dropped off my car for inspection, having made arrangements for a personal rental car. May 7, 2025: I received a text message (no phone call) indicating the inspection was complete and was presented with a $3500 bill to replace the entire fuel tank. May 9 or 12, 2025: Marilyn from Hyundai Riverdale called me regarding my vehicle. She explicitly suggested I "contact your insurance company, advise them you hit something on the road, pay the deductible, and they will pay for the repairs." She then stated, "I know you hit something after April 9th because your fuel tank is now damaged." I denied hitting anything. During this call, she mentioned a "RECALL" related to fuel tanks on all Hyundai Sonatas, which I was never previously made aware of. I questioned why I was being charged if there was a recall for the exact issue I was experiencing. She claimed my car was previously checked and the fuel tank was fine, therefore the cost fell to me. May 14, 2025: Merilyn called to inquire if my insurance would cover the repairs. I informed her I was picking up my vehicle as another Hyundai dealership in Newnan was willing to perform the recall repairs for free. Upon arrival at Riverdale, I faced resistance but demanded my car be released. I was then charged a $200 inspection fee, which I refused to pay. Marilyn then provided my keys and, upon learning I planned to drive to Newnan, stated, "I wouldn't feel right letting you drive this car off the lot and something happening to you. Your vehicle at any moment can blow up due to the fuel tank. It's very dangerous to drive and suggest you get a tow truck." April 11-May 1st I drove that vehicle w/no idea it had the potential to blow up. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATI

Driving on the highway ih35N at 75 mph, my car's engine randomly started violently jerking and then shut off and wouldn't start back up. Had it towed to Hyundai (2022 Hyundai Sonata ~33k miles) took a few days but they repaired it under warranty saying it was bad fuel injectors and they replaced all 4. My car just dying on the highway could of caused a bad accident at that speed. Moving to present day (June 28th, 2025) car is at 56,400 miles and its starting to jerk at low speeds and is getting terrible gas mileage again. I'm taking it back in as I am still under warranty but everything points to fuel injectors again. Only warning lights I get was when the car died on the highway. Just a check engine light.

In February 2024, on a day with snow on the ground no less, my husband was driving over the Verrazano Bridge from Brooklyn, NY to Staten Island, NY, when the car suddenly started shaking and the speed dropped from 50 to 20 in about 10-30seconds. The car started smoking and filling up with fuel fumes. Cars were beeping at him, almost crashing into the back of the car. He was able to make it to safety and had the car towed to the nearest Hyundai Dealership/service. The issue was an injector. On Saturday, [XXX], I got into the car with my two children (age [XXX] and [XXX] old). The car started shaking, all of the check engine lights flew on, the car quickly filled up with fumes, the exhaust was smoking, and the RPM Dial was dancing. I have never been so terrified. The car was towed and again the issue was diagnosed as an injector. Not the same one, a different one. I have been told by my local Hyundai that this is an ongoing issue and that Hyundai only changes 1 at a time, knowing that the others may be faulty. This is unacceptable. These cars need to be recalled immediately. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

****Answers to questions above**** The dealership determined the fuel injector of cylinder 2 to be malfunctioning and replaced it. My safety was put at risk because my car lost all drive power and I could not get out of other people's way.(I was only going 40 but imagine if it happened at 80 mph on an interstate) The dealership reproduced the issue and fixed it. The dealership also stated that several models of Hyundai using the same fuel injectors had come in with the same failures.(10+ cars) Not all on the same cyclinder either. My vehicle has only been inspected by the dealership at this time. There were no warnings leading up to the failure. ****Full Story**** I was driving at about 40 mph through town and experienced total loss of drive power. The vehicle had electric, but little to no response from the gas pedal. I manged to limp the vehicle about 200 yards to a stop light. The rpms dropped to under 300 and the engine began to idle very rough. I shut the car off while at the red light to save it from any potential internal damage. When the light turned green, I almost could not get the car to start and stay running. There was a very strong gas smell at this point, which I had assumed was coming from the engine. I had to put the gas pedal to the floor to keep it running and ride the brakes through the intersection to not hit the vehicle in front of me. After getting through the intersection, I limped it into the parking lot on the other side. This is when I noticed the check engine light had come on. There was no leaking fluids under the hood or the car. I had the vehicle towed to the nearest Hyundai dealership.
