Strong odor of gasoline noticed after driving vehicle and smell remained present for a few hours after ending the drive. Found out that many drivers for the Hyundai Sonata and Kia Optima have had same complaints and the issue is a component of the fuel pump that is cracked. Traced it back to my vehicle, and that in fact is the problem. Since gas is combustible, this is a seriously dangerous defect.

While I was driving, my check engine light came on. It wasn-??t flashing so I was going to continue driving to a parts house (because the dealerships around me were closed) and have them check the codes that were present. Immediately after I had that thought, I noticed the car was smoking and the battery light and the traction control light had come on, so I proceeded to pull over and shut the vehicle off. I got out and noticed the hood had soot on the edges. I called 911 and watched the car go up I-??m flames. This all happened in less than a mile. I noticed a fluid of some sort had sprayed out of my vehicle onto the road and the underneath the vehicle was coated in the fluid. This is still being investigated but I know of a lot of Hyundai/Kia vehicles have caught on fire while driving. I-??m not 100% sure of the cause yet, but I want to document that this did happen to my vehicle. I would love to update as soon as we figure out what has caused the car to catch fire while I was driving.

This is yet another incident of a Sonata Hybrid hybrid flashing a warning to the driver and the the engine shutting down. This time it was Sep 7, 2022 in Morristown, TN. A brief internet search led to this: https://www.tsbsearch.com/Hyundai/17-HC-003-1 indicating that the issue is known to Hyundai. This is definitely a safety issue, this is a known problem, why was no recall issued?

Engine burns 2 quarts of oil a week. Took it in for oil consumption tests and Hyundai figures out ways to not replace these faulty GDI Engines. Also car has a strong gas smell inside car. Maybe gas leaking. Airbag warning light has been on for years. Took it to the dealer in the past they said it's ok(Hub Hyundai Katy TX) but I don't feel confident.

The vehicle is slow to accelerate and as its accelerating it often will jerk or hesitate roughly. There have also been times when accelerating, such as getting on a highway, that the whole (what I assume to be) throttle system will almost stop and it feels like the car is just going to stop right there on the highway. It's very dangerous as cars behind me are also accelerating and not expecting my vehicle to just stop. The vehicle is available for inspection. There are no warning lights, messages, or symptoms prior to the issue. It has not been inspected by anyone yet.

Vehicle suddenly lost power while in operation. Vehicle was in motion approaching an intersection. When left turn indicator was activated, all lights on the instrument panel illuminated, the engine shut off, and power steering was lost all while the Vehicle was in motion approaching a intersection with stop sign. Vehicle was able to stop before entering the intersection, but would not start again and we were stranded in the middle of the road. Electrical systems appeared to be working. Battery and alternator are functioning normally. After Vehicle sat for 20min, it then was able to start and moved out of the road to a safe location. Vehicle was towed to mechanic that confirmed Battery health and alternator functioning. Vehicle was then taken to dealership for recall 210 safety repair. Dealership service unable to determine cause for loss of power while Vehicle in operation. No explanation, offer of additional service, or remedy has been offered despite requests. I do not feel it is safe to operate this vehicle in the absence of information related to the sudden loss of power during normal operation. Had this occurred in another setting with more traffic or less room for safely coasting to a stop, serious injury or worse could have resulted. The vehicle is still eligible for the 10yr 100k mile powertrain warranty and I am the original owner. We do not feel we can safely operate this vehicle and need guidance on how to proceed with pursuing a remedy to the situation from the vehicle manufacturer.

While driving POV from work, I began smelling fuel in the air conditioning system from external intake. Upon further discovery, the high pressure fuel pump was found to be dislodged from the engine, due to a sheered bolt. This allowed fuel to spill out on the manifold and engine, also reducing power for acceleration. This issue could have caused a vehicle fire that could have engulfed the cabin if ignited.

I took my vehicle to the dealership to have recommended service completed which included the fuel tank air filter. To complete this operation, the mechanic performed an M.P.I which showed that the fuel pump was leaking. I'm not an expert on anything, but I can't imagine a time that fuel leak is good. What's really concerning is that if I hadn't had the vehicle in for routine maintenance, this problem wouldn't have been found which could have led to catastrophic issues. I find it hard to believe that it's typical that a fuel pump fail with under 60,000 miles on the vehicle- who knows how long the fuel pump had been leaking. My tech at the dealership told me that they have seen this same problem with other 2015 Sonatas so I am certainly not the only one to experience this issue. I had to return the car to the dealership a few months ago for a recall that involved a fuel leak. I wonder if all of the fuel leak issues have been dealt with, fuel leak wise, with this vehicle. The sub total for this repair was $817.66. Thank you, [XXX] INFORMATION Redacted PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).

Heavy odor of gas in backseat and truck. Noticed odor in garage while parked and when driving had to roll down windows! I took to mechanic. He found a crack in fuel tank. My Hyundai had been at the dealership that week with them changing the oil and rotating tires but they did not acknowledge it! Mechanic informed me that this could be a very dangerous situation and should not be driven. Dealership no help.

Vehicle driver received audio and visual alert while driving at high rate of speed that the "hybrid warning failed and to check hybrid system-turn engine off" and to pull over safely. However, the vehicle locked and lost all power making it impossible to safely exit the interstate almost instantly after the alarm. Upon research, I manage a large vehicle fleet, we have multiple other Sonata's with the same issue-and there is a tsb for this known safety failure (17-hc-003-1).

The car suddenly loses the ability to accelerate making it very stressful to drive as you are not certain when this will happen. At first it is intermittent but eventually it simply stays that way once the issue begins while you are driving, hence the car will have an almost impossible time retaining speed on the highway or accelerating at a light or as you merge onto highways. Changing the driver mode to sport appears to have a positive effect as it causes much more aggressive gear shifting but it then stays in the same gear for too long reaching rps that feel unsafe for the engine itself. This is now the third tie this happens and it is also the more severe manifestation of the problem, . the first time the dealer asserted they were not able to diagnose it but returned the car without the problem. The second time it happened they apologized and said that it was an issue with the engines computer algorithm, that apparently the computer learns from the way in which one drives and so is adaptive but that sometimes it can become corrupted. This third time the dealer told me it would take only a couple of hours to fix but now it has been three days and they have not called me back. They did leave a message that apparently they are ordering parts and will be fixing it. My issue now is that its a third time and it is clear that something in the car is defective and now we are going to be almost completely paranoid of it happening again at a critically dangerous intersection or merge area. We have been lucky so far but it is a family car and I do not feel safe in the car anymore given the repeating nature of this problem and the lack of information out there form the manufacturer as to what exactly is going on.
