2015 Hyundai Sonata fuel system complaints
Page 3 of 4: complaints 41 to 70 of 87, newest first, as owners wrote them.
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 top of the low pressure fuel pump in the fuel tank was cracked. A strong fuel smell was present near the rear of the vehicle. When the vehicle was placed on jack stands, leaking fuel was visible on the sides of the fuel tank. The rear seat was removed, fuel pump access cover was removed, ignition was turned on and fuel was observed leaking from cracks on the top of the low pressure fuel pump. This is a huge safety concern due to fuel leaking from the fuel tank. I know for a fact this is not an isolated incident, you can watch YouTube videos of others with the exact same problem. The dealers want $1K+ to repair. I was an ASE Certified mechanic for 20+ years experience, I purchased an OEM fuel pump through an online retailer for ~$600 and replaced it myself. Problem solved, but for how long? There were no warning lamps or messages, the only sign was the strong smell of fuel.
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.
Anytime the car needs a repair on something (fuel pump, inhibitor switch, etc.) in the middle of driving the car will flash "hybrid system warning safely stop and do not drive" and then either slow to 40mph then die, or just die completely. This has happened 3 times before I took it in to be fixed. A few months later, it happens again. It doesn't matter what is wrong with the car, the car just senses an issue and dies in the middle of driving. Very unsafe!

The vehicle has a very strong smell of gasoline and has been taken to the repair shop after spark plug flooding. Vehicle still smells like gas after repair but runs now.
At low idle (stopping) car stalls out when stepping on gas. The RPMs run extremely high and very low at idle causing panic. The vehicle also stalled at full speed on highway but all electrical was still working. Car tends to sputter and jump while shifting.
The contact owns a 2015 Hyundai Sonata. The contact stated that while driving at 20 MPH, the vehicle inadvertently stalled. The check engine warning light illuminated. The contact was able to veer to the side of the road. The contact stated that the vehicle restarted independently after a few minutes and she continued to drive. The dealer was notified of the failure and informed the contact that the vehicle was not included in any open recalls. The vehicle was taken to a local Pep Boys who diagnosed that the fuel system and fuel pump had failed. The contact stated that the failure reoccurred while driving on the highway at an undisclosed speed. The contact was able to push the vehicle to the side of the road with assistance. The vehicle was towed to the contact's residence. The manufacturer was not notified of the failure. The vehicle was not repaired. The failure mileage was approximately 137,438.
The car caught fire. I only had the car for 3 weeks. I had just started the car for work. There were no warning lights on. If some unknown guy have not told me to get out my car i would had died.
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).
Was driving on sunrise highway doing about 55 MPH when all of a sudden my car start losing all power acceleration and would not go pass 20/30 MPH. Was able to get to side of highway. But now car has issues picking up acceleration. Could have caused a major accident.

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.

Parked or windows up gasoline vapor is inside vehicle. Source is a cracking fuel pump. Located under rear seat underneath an access cover. Youtube has videos. I'm not on youtube that is another party. I live in arizona and I park my vehicle on driveway, it gets really hot. I do not believe the plastic that cracker can take the heat!
When excelerationhe care makes a noise, sounds like shavings of metal in engine some days are worse then others. I've taken it to two different hyundai dealers and one heard it and said they have no idea what it is and have others with same problem and the other dealer said they didn't hear anything. My husband has bad hearing but one day he drove it to work and said he finally heard it as well. I do notice that the pick up is hesitant making it hard to stay in flow with the traffic at times. My gas per milage performance has decreased some what as well which
Applying the brakes at a stop requires the brake pedal to be firmly held to the floor otherwise the engine will start reviving up and move out fast if the brake is released. Also appears that the transmission when moving the shifter to park does not mean the car is in park. I did this once in a store parking lot. The shift handle was in park. But as soon as I took my foot off the brake and opened the door car took off. Caused $ 6,700 to fix all the damage. Engine does not come off fast idle. When I first got the car. Idle RPM was between 500 and 750. Now the idle never goes below 1200-1300 RPM. I tried various brands and grades of gas including ethanol free unleaded but nothing helped.
While driving the vehicle I smelt and seen smoke and then a pop coming from the car and within seconds flames coming up from outside of the driver door. Pulled over and within 3 minutes the car was fully involved in flames. Was driving down a city street going approximately 35 MPH.
The gas tank lever goes down as if I were sipping on the gasoline. This has been going on since I purchased the used vehicle around june or july 2018
My fuel filler door opener is not working. Hyundai has this recall for other vehicles but not for my model and year, this is clearly something wrong with their product and the want me to pay up to $500 in parts and labor?
Vehicle stalls. Randomly. Acceleration stalls randomly. Engine dies parked randomly. Seems so decelerate/brake/. Drag while driving. Recall o comport n program only. Warranty for original owner only. Recalled made in. 2011-2014 sonata my 2015 sonata sport has the same engine
Whenever I accelerate on the highway my engine would rev to a high RPM with a delayed reaction in order to get the car accelerated. Also, whenever I slow down my car for a stop light or stop sign, my engine would rev to a high RPM to slow down my car. I asked the hyundai dealerships, they said the everything is okay, however I can tell right away there's a difference with my 2015 hyundai sonata vs my girlfriends 2015 hyundai sonata, exactly the same year and model and trim, but the drive is totally different. Also, I can also tell because the mpg on my car is far lower than my girlfriends. And she has a heavy foot on the gas petal. It doesn't make sense. The hyundai dealership also reset the computer of the car, but no difference.
1) gas tank never takes more than 15 gallons of gas when the gas tank was supposed to hold 18 gallons. One day the fuel computer showed the range as 15 miles and the gas tank still took only 15 gallons from the pump even when the car gets a mileage of more than 30 mpg. Also, the pump abruptly stops in between and I have to restart pumping the fuel. This is either a fuel guage problem showing the gas tank is nearly empty when its really not or a gas tank problem. Online research indicates that multiple people have this problem. 2) the adaptive cruise control is really jerky and slams the breaks suddenly and accelerates abruptly resulting in a very jerky ride.
