FUEL/PROPULSION SYSTEM
On 3 separate occasions the vehicle decelerated, lights flickered and stated to produce a burning smell through the engine. Each time the car would not allow me to accelerate and eventually stalled out. The car would no immediately start. After a few minutes it would start but not accelerate. After about 30 minutes it would start and would drive about 5-15 mph, enough to get me to my location. On the first occasion I was coming home late in the evening after working a 12 hour shift and had to have a family member get me after being stranded by the side of the road. The second time I was taking my 4 to son to his planned surgery in a bigger city and it broke down on the way. It was not safe driving in the city barely being able to excel but we did it for my son. The third time I was in a larger time in traffic and missed an appointment as I tried to stear my decelerating vehicle out of multiple lanes of traffic to a safe location. I could not use the air conditioner while I attempted to let it rest in 100°+ heat. Each time the lights would flicker and dim. There would be a smoke from the exhaust. After the first 2 occurrences we took it to the dealership but they were not able to replicate the problem or identify a causative code. During the last occurrence we were able to get it to the dealership very slowly and they deemed it to be the fuel injector malfunctioning. This was fixed after about a week or so of being in the shop . About a week or two after the fuel injector was fixed the check engine light came on. We took it back into the service department and they "reset" the system thinking it was an error. The light came back on in less than 24 hours. The vehicle has been running a little harder, not as fast or responsive as normal. A service/evaluation date was scheduled and the code was checked indicating it was likely the catalytic converter. We scheduled another service appointment once the part was in which is 2 weeks from the evaluation appointment.

The vehicle itself shakes when accelerating and will start to fail once 60mph is hit. It will also cut out when left turns are made...I have met 4 people with the exact same issues who received recalls but I am not sure why my car is not included. I was almost rear ended on the highway by a semi with my pregnant wife and 4 year old son in the car because of the engine failure.

ELECTRICAL SYSTEM
Blower motor stopped working. Same issue has now happened on my 2021 Hyundai Sonata Limited. I have been waiting now three months to have my 2020 Sonata to be fixed. Hyundai technician said the wiring harness had a crack and it’s why my 2020 Sonata’s Blower motor stopped working. It’s now three months since they diagnosed and ordered the wiring harness but supposedly it’s still on back order and I’m left with a hot car this entire summer and possibly a cold car come this winter. Now it looks like I will have the same issue with my 2021 Hyundai Sonta Limited leaving me with two cars without A/C or Heat.

The contact owns a 2019 Hyundai Sonata. The contact stated that after the vehicle was purchased, the vehicle was taken for an oil change. The contact stated that the very next day he checked the dipstick and became aware that there was no oil on the dipstick. There was no warning light illuminated. The dealer was called, and the contact was informed that there might be an oil consumption failure with the vehicle. The vehicle was taken to the dealer for an oil consumption test; however, the contact stated that he was not able to pay for the oil consumption test to be performed. The contact stated that the vehicle was not yet diagnosed or repaired. The manufacturer was notified of the failure. The failure mileage was 118,000.

POWER TRAIN
What component or system failed or malfunctioned, and is it available for inspection upon request? Vehicle stopped accelerating and flashing check engine light went on. Vehicle reported "Check Hybrid System." Dealer believes it was loose pins in a HCULDC connector that may have caused loss of communication. How was your safety or the safety of others put at risk? Lost acceleration on a highway and was nearly hit trying to get off of the road. Has the problem been reproduced or confirmed by a dealer or independent service center? Piazza Hyundai of Pottstown, PA reproduced the issue. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? Dealer secured loose pins. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? No.

FUEL/PROPULSION SYSTEM
There is an issue with the 2020+ Hyuandai sonatas and Kia K5 models. The valves in my gas tank had failed. Causing pressure and gas vapors to be trapped inside the tank. The pressure in my tank has swollen my gas tank to the point where it’s bent the metal frame underneath my backseat, lifting my backseat off its base. My car is a literal tricking time bomb because the tank will eventually burst. There’s also a strong smell of gas coming from underneath the backseat. There’s been a new story on this issue already. Kia has acknowledged the issue and did recalls. Hyundai has not. Many owners of the Sonata are having this same exact issue according to Reddit posts. I took my vehicle to the dealer, got it diagnosed, was quoted $2900+. I was told it was an extreme safety hazard due to the pressure in the tank and the gas leak. The tank has swollen so much that it’s pressing against the exhaust. I’m out of warranty and they expect me to pay out of pocket. I have no where near $3000. I use my car for work and have no choice but to drive it. Please help.

ELECTRICAL SYSTEM
Fuse box has a defect causing the AC blower motor to intermittently not work. Appears to be the result of loose connections between the fuse box and the fuse itself. The receptacle for the fuse is clearly burnt/melting, and appears to pose as a fire hazard as a result. The car is currently in the shop for repair on this part, but won't likely be fixed for a month+. I do have photos of the damaged parts, should it be requested. The car was taken into a Hyundai dealership for repair work in November 2023, and I was told the fuse had blown but that they fixed it. I was never told about the box appearing damaged/melting at that time, or this being a common problem. It worked again till July 2024. Car was just dropped off 9/3, due to backlog of cars at dealership. The only symptom of issue was the AC blower motor would stop working at random. It would turn back on/off while driving. This seems to be due to the loose connections between fuse box and fuse.

AIR BAGS, ELECTRICAL SYSTEM
The air bag sensor located in the front passenger seat does not function. It is available for inspection upon request. Because the sensor doesn't engage, the passenger-side air bag will not deploy in the event of an accident, leaving my passenger at risk of serious injury or death. The Hyundai of Cool Springs dealership in Franklin, TN, has inspected the car and confirmed that the sensor is not functioning. The sensor, if properly working, will show a glowing red light on the dashboard that goes on when a passenger sits in the passenger seat, and goes off after a few seconds. In the case of my car, however, the dashboard light goes on when a passenger sits and stays on (glowing red) the entire time the passenger is seated. This defective dashboard light, according to the Hyundai service technician, indicates that the sensor needs to be replaced. The cost the technician quoted is prohibitive at $3,500.

AIR BAGS
2011-2013 SONATA (YF) AND AIRBAG CONTROL UNIT (RECALL CAMPAIGN 174) I did the recall at Sterling Mcall in 10/2022 and I had no airbag light before after I did the recall the airbag light came on the dashboard -The dealers scanned the car and it is visible on the baseboard however the dealer is reluctant to repair it and asked 3 weeks of diagnostic and 500 dollars only for diagnostic and nothing about the repair I showed them the recall repair failure is their responsibility and the airbag should be permanently fixed not to be worried about it from time to time The dealer's excuse is that car titles salvage however the car is being serviced at the dealer and is passing state inspection every year. I filed a complaint in BBB nad the dealer failed to respond and sent me a threatening letter for emailing their executive.

ENGINE, ELECTRICAL SYSTEM
On three separate occasions over the last two months, while driving, an alert comes on that says check hybrid system then the vehicle powers off. When this happens, you lose the ability to accelerate break steer, and I have been lucky each of those three times and that I was in a situation where there was not much traffic. I am not able to drive the vehicle at this time. I have reported the problem to Hyundai and they want me to drive the vehicle to the dealership for another check of it. They have looked at it once before and have not been able to diagnose a problem. It is unsafe to drive and they are not willing to assist in getting the vehicle to the dealership without me getting it over there.

ENGINE
To whom it may concern, I would like to inform you that I have been experiencing engine power loss and oil evaporation from my Sonata. In fact, I took the vehicle for an oil change in April 26, 2024 and by August 1, 2024, my car was not accelarating and the dashboard was completely illuminated with the engine, air bags and suspension lights. Upon inspection of engine oil dipstick, I was made aware that my oil was missing (evaporated) without any visual undercarriage drips. Therefore, I added 4 qts of synthetic oil to my car recently replaced oil and the car continued without power. Upon connecting a vehicle code reader, it was reported that a spark plug was malfunctioning and I continue with its replacement. To date the vehicle continues to have engine loss of power episodes. Can someone please help as I do not want to die in this vehicle due to a manufacturer's unannounced/undisclosed engine issue. Thank you for your time and consideration.

While driving, car started to lose power. Warning lights started flashing to turn off vehicle to recharge battery. Car lost all power. Car was towed to dealership. Dealer started diagnostic testing, and first thing that was noted is that all oil had drained from car and that crank shaft may now be damaged. Prior to incident, no warning lights came on for service, engine or oil lamp. Dealer and internet searched confirm this has been happening to this model recently.

FUEL/PROPULSION SYSTEM
My low pressure fuel hose has a leak. The amount of gasoline that is spraying on my spark plugs and engine is concerning. The gas fume smell coming in through the vent was horrible. After finding this leak I came to the conclusion that I am very lucky My car didn’t catch fire while I was driving. For some reason there is already a recall in place that includes my vehicle year but does not include my vehicle Vin. How do I get my vehicle included in this recall so that it can get repaired? The recall in question is NHTSA number 227 or 22V – 314. At this time, the car is sitting in my driveway and I am not inclined to move it until I know it can get repaired. At that time, I will have it towed to the dealership.

UNKNOWN OR OTHER
When driving (at any speed) car error message comes up that says "Hybryd system warning safely stop and do not drive" then when that light goes out a new warning comes up that says "check brake" at this time the car will slow itself down until the car stops completely - even if you have your foot all the way on the gas pedal. There's no pattern to when it happens, it can happen on any drive at any time. When this happens all I can do is turn the car off and wait to restart car to keep driving. The front brakes have replaced, the back brakes and rotors have been replaced and the brake pump was replaced but, the problem persists. Primarily this is a safety issue if I'm on the highway, or anywhere I can't really pull over. A perfect example of this is on 8/31/2024 my son received a warning citation for "Improper Stopping" the remarks on the citation say " was parked on side of roadway due to car not wanting to accelerate but, could not move outside of the roadway". Basically the car slowed down but, completely shut down in an area that wasn't safe to be parked or sitting. It's dangerous for me and any other driver on the road that's behind me or on either side of me. After researching online it seems this is a common issue that Hyundai has not figured out yet. Other consumers have spent thousands on repairs thru Hyundai and still have not resolved the issue. Please help me figure this out.
