On [XXX] my 2011 Hyundai Sonata seized and all lights illuminated on the dash while accelerating on to a busy street. I was able to pull to the side of the road but unable to restart the vehicle. I had it towed to Wesley Chapel Hyundai (27000 Wesley Chapel Blvd., Wesley Chapel, FL 33544) who notified me that there was an oil pan leak which was the possible cause of the engine failing. They corrected that issue and completed an oil change on 3/14/2025. I picked up the vehicle and there were no issues on the drive home which was approximately 11 miles. Then on [XXX] after driving approximately 24 miles to my place of employment, the engine started knocking but I was able to arrive and park with no issues. I immediately turned the vehicle off and contacted the closest dealership to have it towed there which was Courtesy Hyundai (3810 W Hillsborough Ave, Tampa, FL 33614). I informed them that the vehicle was on it's way there and to notify me when it arrived. It wasn't until I called several hours later that they advised me the vehicle was received and that they would be submitting a claim to Hyundai Motors of America for the Engine. I had to continuously call to get updates as no one would contact me. I then was told that HMA was requesting service records. I emailed those records to the service advisor on 3/20/2025. I had not heard anything for about a week so I contacted the Service Manager who stated HMA is requesting additional service records. I asked why I was not informed sooner but was unable to get a real answer. I then forwarded those documents directly to the manager on 3/28/25. I was then notified on 4/1/25 that HMA had denied the claim due to negligence of the motor despite providing the requested documents as well as confirming via Hyundai's website that my vehicle was affected by the Sonata Engine Connecting Rod Bearing Inspection Recall Campaign. I am now being quoted $4059.89 + tax to replace the engine. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The contact owns a 2013 Hyundai Sonata. The contact had received an undisclosed NHTSA recall campaign, and the vehicle was repaired under the recall. The contact stated that the check engine warning light had been illuminated since the vehicle was picked up from the dealer after the recall repair. The contact stated that on a separate occasion, the vehicle failed to start. The vehicle was towed to an independent mechanic where the vehicle was diagnosed and determined that the engine had seized. The vehicle was not repaired. The contact then towed the vehicle to the dealer. The vehicle was not diagnosed or repaired. The manufacturer was notified of the failure. The vehicle remained at the dealer and had not been driven since. The approximate failure mileage was 150,000.

SERVICE BRAKES, STEERING
I am reporting multiple serious issues with my 2016 Hyundai Sonata Sport 2.0, which has only 30,000 miles. Despite the low mileage, the vehicle is experiencing major safety and quality problems. The Electronic Stability Control (ESC) light stays on constantly, indicating a system failure. On startup, the car sometimes applies the brakes by itself, and there’s a loud noise like something is stuck or grinding. The traction control light also comes on during this. While driving, the car will suddenly slow down on its own, even when I’m not braking. When I press the gas pedal, it barely responds or takes too long to accelerate. Sometimes, this happens at the same time as the ESC warning, which feels extremely unsafe — especially on highways or in traffic. The push-to-start button often delays before the engine turns over, which is abnormal. The A/C system only blows warm air, regardless of temperature settings, and no cold air comes out. I also have a serious issue with the paint peeling off in large chunks from the body of the car. It’s happening despite proper care, and I’ve seen other Hyundai Sonatas of the same year with the same issue, which suggests a widespread paint defect. These issues have not yet been diagnosed by a dealership, but given the low mileage and frequency, I believe this model may have serious defects in safety systems and paint quality. I’m very concerned for my safety and request a full investigation.

This is the third time after 3 “repairs” that I have had my car at the dealer in less than a year. Car went into “limp” mode while driving down the highway causing car to stall and not go over 20 mph. First time they said it was a technical update needing done. Second time said low battery power causing issue so I purchased $300 battery from dealer and now showing cylinder 4 misfire and recommend replacing spark plugs and oil combustion testing due to having to add 3 quarts of oil every 230 miles due to excessive oil consumption. Dealer said this will not fix the issue however so why would I pay to have it done if it won’t fix the issue. Luckily these three incidents of engine power loss hasn’t caused me to have an accident but what If in 3 months and my engine loses power without warning for the 4th time in a year it dies cause an accident. I have a case open with Hyundai but am getting nowhere. I feel like a measly engine replacement would cost less than it will cost if this causes a major accident soon.

POWER TRAIN, FUEL/PROPULSION SYSTEM, VEHICLE SPEED CONTROL
On or about November 13, 2024 our Hyundai Sonata 2020 gas tank almost exploded. We drove our vehicle to a dealership so that it could be checked because we kept hearing something that sounded like a loud pop / thumb underneath our vehicle. We had already been receiving notifications of a powertrain issue with the vehicle for years (without the dealership resolving the issue). So we were taking the vehicle in for numerous reasons when, the minute we drove our vehicle into the service bay (of a new and unrelated dealership) we were told that Hyundai's Corporate branch has ordered our vehicle grounded and told us we COULD NOT LEAVE with our vehicle or drive our vehicle off the dealership's lot. We were advised that our vehicle had almost exploded and that we were lucky to have brought the vehicle in. We were told that our vehicle should have never left the lot the day we purchased it brand new. We were told that our vehicle's backseats had detached and separated away from the frame of the vehicle. Our vehicle has been at the dealership since the day of the incident (e.g., on or about November 13, 2024). Our vehicle is still under factory warranty and powertrain warranty and Hyundai was not given us an end in sight or advised the public of the issue with their vehicles. WE were told that the vehicles needs repairs such as: 1. The vehicle needs the fuel tank assy and all of the parts for the tank, check valve, and campaign sticker: Please see TSB: 24-01-02OH

While driving under normal highway conditions, the sunroof detached from the vehicle while still in the closed position. This caused extreme danger to other drivers and property and could have caused a fatality if it would have hit a motorcyclist or other unprotected person. There was a recall for this (Recall Campaign 152: 2015-2016 Sonata Panoramic Sunroof) and the vehicle was delivered to the dealer during the recall period for inspection and presumed fix. There was no warning that anything was wrong previous to the incident.

ENGINE
Due to a recall Hyundai promised a lifetime extended warranty on the engine of my 2014 Hyundai Sonata concerning a defect in the engine manufacturing. We're as metal shavings can cause rod bearings to wear out causing what is known as engine knocking noise. Well my engine is knocking, and I was told by a license certified mechanic that it's my rod bearings & that the engine is fixing to throw a rod. This is covered under the extended lifetime warranty. When I called Hyundai they said we aren't going to fix the issue because the vehicle has a salvaged title. I had a consumer rear ended me years ago, there insurance company totaled out my car which was not totaled. Only minor rear damage. I ended up keeping the car and it drove fine, no engine damage due to the wreck on rear end damage. This shouldn't stop my rights to a new engine which Hyundai promised during a lifetime extension of the engine. This is considered unfair Deceptive Trade Practice Act violation.

FUEL/PROPULSION SYSTEM
The fuel pump where the fuel line connects to it is cracked and squirting fuel all over that area. Some time ago I started smelling fuel when getting close to the vehicle or when opening windows. Took it to a shop to have it checked out and the technician couldn’t find the problem, since there is no check engine light on or any type of warning. A few days ago I decided to check the bottom part of the fuel tank and noticed that there were traces of leaking fluid. Reached to it and checked it closely and certainly was fuel dripping. Checked the top of the tank where the fuel pump is and found out that the problem was there. Did some research online and found out that that’s a very common fail. I Would like to have it investigated and recall all those failing cars for my safety, my family’s safety and everyone else that trusted this company and is letting us down. First time I noticed this was back in 2022 and is when I took it to the shop.

ENGINE, POWER TRAIN, FUEL/PROPULSION SYSTEM
My 2018 Hyundai Sonata (approx. 60,000 miles) began consuming excessive oil, and the engine started smoking while driving. My wife barely made it to the dealership — the car was unsafe, struggled to stay running, and visibly smoked from under the hood. Hyundai acknowledged the oil issue but refused to cover engine replacement. Instead, they approved a one-time combustion chamber cleaning and requested we drive the car 1,000 miles to "see if it gets better." This is a major safety concern. The vehicle is part of a group of Hyundai models known to have defective Theta II engines that have led to engine failure, fire risk, and recalls. This issue is widespread, and Hyundai is not taking proper responsibility for defective engines in cars like mine.

The engine is burning through oil at a rapid rate. I probably get 2,000 - 2,500 miles before it needs a complete refill and the problem is getting worse. I was not due for an oil change recently around 2,500 miles and my engine started shaking, took it to the shop and the oil was gone without the oil light going off. This resulted in me needing to replace spark plugs and all engine coils. The repair shop recommended I sell my car because of the amount of Hyundai's he sees with this issue.
