On [xxx] at approximately [xxx], my [xxx] daughter was using my car to go to work. When she called us and informed my husband that the car did not start. At that point he asked to video call him so that he can visually see what was going on. She was directed to turn on the car again at and that point, the car started then smoke was noticed from coming out of the hood. My daughter managed to open the hood where flames emerged from the center of the engine. She then ran in the house to get a fire extinguisher and managed to put it out and it reignited. She then made a second attempt with another fire extinguisher where it briefly subsided and then grew larger. At that point the fire dept arrived and successfully extinguished the fire and deemed the car totaled after the fire marshall carefully inspected the car. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).
Unknown cought fire under the hood was engulfed within minutes.
When driving. Slow down to turn or to use round about car goes into ev. When I go to accelerate the gas motor will not re engage and the hybrid alarm system will go off. I lose all power to go any where. I have to pull over shut my car off give it a min then restart so the motor will come back on so I can drive again. I have to do this mulitple time in a 20 mile drive.
I own a 2012 Hyundai Sonata with 114000 miles on it. I have had it since 62000 miles and have replaced a lot of parts to keep it running well. My current issue is the hybrid charging system warning light comes on and the hybrid system will stop working when it does this. It has already left me stuck on the side of the road once. When it did this the car stoped running at a stop sign. Luckily I was able to get car off the road. It shows the pull over hybrid charging system error. So I have tried replacing the battery , replacing the main battery fuse on the 12 volt battery and replacing the orange hybrid battery main fuse. The car still does not function properly and have had it diagnosed with a professional shop and they could not resolve the problem.
On July 8th 2024 I was driving my already troubled 2012 Hyundai Sonata when I started to smell strong odor of unburnt gasoline which immediately had my red flags go up, I safely pulled off the roadway and opened the hood and the fumes got stronger and stronger, I removed the plastic top engine cover to discover the foam on the underside of the plastic cover was sopping wet with gasoline, and witnessed what appears to be some sort of line or horse carrying fuel to the high pressure fuel pump squirting out gasoline right on to the hot manifold which immediately panicked me and I put tue plastic engine cover back over the top of the squirting fuel line. It comes directly off of the front of the fuel pump with a quick connect plastic hose that seems to have become brittle from the constant heat cool cycles of the engine compartment. I immediately unplugged the car battery negative and was able to gather some disposable towels I had handy in the trunk and was able to place them atop the squirting fuel line and below it as well. But the entire area that houses the spark plugs was full of gasoline and far too much fuel for me to mop up with the towels I had on hand. This is very concerning to me that a plastic hose and connector would be used in such a scenario seeing as how common sense would tell you that over time plastic will become brittle especially with a heating cooling cycle, and I find it even more disturbing that upon contacting the dealership that I was informed that my vehicle was not included in the said faulty fuel line which has led to dangerous thermal events ending in complete loss of vehicle and potential for life loss. So in addition to the now faulty replacement engine that is in my vehicle, along with the non functioning turbo system, and the melted tail light housings, I now have to pay out of pocket to correct a mistake of Hyundai, I have lost total faith in the brand and in my particular vehicle. I do not feel safe driving it and it will sit.
The hybrid warning system came on. The ready light is blinking and beeping. The car is jerking.
I’ve been having issues with my gas gauge not recognizing how much gas I have in my car. I can fill my tank up, and the gas light constantly stays on. I’ve been looking online and came across other Hyundai owners having the same problem. I also have been having what seems to be an electrical issue where my passenger door, does not open and it’s intermittent which also seems to be connected to why my car ceiling light won’t turn on all the time. Lastly, I have to constantly change the head light bulbs and the break light bulb. I’ve owned my car for 3 1/2 years now, and I shouldn’t have to keep having to put money into it when it seems to be a known issue.
On the morning of April 15, 2024, at around 6 a. M. , our 2012 Hyundai Sonata hybrid unexpectedly caught fire and exploded in front of our house. This incident occurred shortly after I started the car and left it to warm up. Smoke and flames emerged from under the hood, quickly escalating until the front of the vehicle exploded, shattering the windows and extensively damaging the driver and passenger sides. Previously, we had noticed a fuel odor emanating from the hood, which we suspected was related to a known fuel recall issue. We brought the vehicle to the manufacturer's attention, hoping for a resolution under the recall. Unfortunately, the manufacturer did not address the fuel smell as part of the recall services and instead billed us for unrelated repairs. This oversight on their part raises serious concerns about the safety and reliability of the recall process and the manufacturer's accountability in ensuring the safety of their vehicles.
My Sonata 2012 the engine was replaced it seized up on the highway. Since then ive had multiple issues; 1. My brake pedal seems to get pulled to the floor all the way at random times I have to pump the brake for it to release itself. 2. Ive replaced the purge valve 3 going on 4 times as well as the cadilac converter due to it being clogged. 3. My car is so loud it makes a hissing noise and a winding sound people say its my transmission going out but no one can pinpoint the problem. 4. My brake lights and head lights go out all the time been replaced bout 100 times. Lights on the dash r on; airbag, check engine tire pressure . Please I need my vehicle looked over by a professional and or help replacing these issues ASAP.
Approx one year post engine replacement, and 2 weeks prior turbo system replacement, I am having major issues with my Sonatait struggles to stay started, it always hesitates and doesn't want to move when I press accelerator, shakes jolts and shudders, the smell of burning oil comes thru the vents and even smoke comes out from under the vehicle. The engine is leaking masses amounts of oil that seem to be leaking from all over the under carriage and half way to the back underneath the car, oil is in the wheel wells, and even splashed on the rims, the spark plugs are covered in oil, huge plums of white and dark smoke come out of the tailpipes, literally blinding anyone behind me, press the accelerator to the floor and it just shudders and smokes even more, check engine light is on and states malfunctioning turbo system, boost pressure sensor malfunction, sluggish will not gain speed, oil within the turbo blow by hose and in intake hose area, now I have coolant pouring out and the reservoir the coolant will be literally boiling. This is not good at all especially after a year post engine replacement and turbo replacement. When the car is started I push start and car struggles to start the starter keeps screeching and car shudders for a good 45 seconds before it either dies out or finally starts. This vehicle should be a lemon and bought back regardless of age condition etc. A vehicle after engine replacement of only one year should not be pouring oil out of the engine, failed head gaskets,misfiring and leaking coolant. I keep receiving recall notice after recall notice in the mail stating I have recalls that need to be addressed but when checking using my VIN it says there are no recalls needing fixing, that makes me uneasy and I don't feel safe driving the vehicle I lost faith in it all together.
There was a complaint on your site that is exactly what happened to my car. While driving with foot on accelerator, acceleration/ current speed will randomly just stop. 1-1- once I fully release the accelerator and then reengage the accelerator problem goes away. This is very random as to when it happens, and will happen multiple times in a row some times. . . And other times happens once and doesn't the rest of the trip. Safety is put at risk. There's only 38,000 miles on this vehicle. My mechanic can't find it because it's not doing it. The engine light doesn't come on and neither does a code. It does this on a freeway and the streets. This is extremely scary and dangerous.
When decelerating, the vehicle will have a hard down shift or it feels like it accelerates with your foot on the brake after a hard downshift. Once you have come to a complete stop and you accelerate into traffic, it bogs down and does not move forward. It is dangerous to merge into traffic on a city street or in the highway. Our mechanic and the dealer cannot find anything. It is not predictable but it is dangerous to drive.
Daughter was driving her car on interstate, doing 75, in the middle of traffic when the car would jerk and then loose power. The gas petal stopped working and the check engine light would come on. She had to make her way over to the shoulder, without causing an accident. Once car gets shut off and you wait a few minutes, you can start it and drive it home. This has happened about 4 times now. We are lucky that this hasn't caused an accident! this last time (yesterday), the check engine light stayed on and we were able to hook up the dianostic reader and it read the code for the crankshaft positioning sensor a circut. It says online that this is a common problem with that car and is very dangerous. How is this not up for a recall? my daughter is scared to drive her car.

I recently purchased a Hyundai Sonata hybrid with 132k miles on it and it has been driving fine for at least two weeks until a few days back the car has been displaying a recurring alarm on the dashboard telling " hybrid system warming! safely stop and do not drive " now as soon as I turn on the vehicle the alarm comes on immediately. It's been a week since the car is technically inoperable because if I attempt to drive the car it makes this horrible grinding sound which is terrifying considering if I drive like this it would probably cause more damage to the car, and I have look for information on this issue and have found many of these cases over the years that I can relate to but unfortunately there's no a recall of this problem. I'm taking the car to the dealership soon but I don't have any hopes that they will find a permanent fix for this since nobody has apparently. I'm just trying find some help with this issue. So far I just have lots of regrets about this purchase and just hoping I can find some help with this matter.
When I start the vehicle in the morning I leave the neighborhood going around 15mph and the car loses power. I have to let off the gas completely then reapply but it still continues to studder. I applied the slapstick sift mode and noticed it does this in first and fourth gear. In automatic you can’t see it.
Illumination of the malfunction indicator lamp and/or abs (anti-lock brake system) light. My 2012 Sonata hybrid has been towed twice to key Hyundai dealer in jacksonville, FL. They charged me several thousand dollars and the vehicle abs lamp remains illuminated. The dealership did not offer me alternative transportation and I feel unsafe driving the vehicle. On Friday November 12th they blamed the brake lamp illumination on the hybrid main battery and gave me an estimate of $12,900. 00 to replace the battery. The first time I took the vehicle in for this problem my vehicle was still under 10 year/100,000 mile warranty. My car has approximately only 35,000 miles driven. They did not honor the warranty. This is a brake issue not a battery issue.
I purchased the car 9/1/21. 4 months ago I repaired an issue with the fuel pump and fuel rail. Now it's doing the same thing. Code p0087. I looked up to see if there were any recalls and there aren't any open recalls; however the recall #180 is the issue I am having with my car. Would this be covered under the #180 recall?.
Vehicle caught on fire.
The contact owns a 2012 Hyundai Sonata hybrid. The contact stated that once car has warmed up, while driving at low speed or starting to move after a stop, she vehicle hesitated and stalled while depressing the accelerator pedal. This is a serious risk hazard as the car barely moves at intersections where it is a risk of getting hit by incoming cars. There was no warning light illuminated. The contact had taken the vehicle to multiple independent mechanics as well as Hyundai dealerships who were all unable to diagnose the failure due to no warning lights illuminating on the instrument panel and no codes getting registered in the ecu. The contact then got the car evaluated by another Hyundai dealership in order to exchange it for a new vehicle and mentioned this problem. This time the dealership mechanics claimed to have seen this same problem at several occasion and that the cause was failing electric motor (when warming up) which needs to be replaced along with transmission. They also said this failure would eventually lead to the car no longer being usable at all (catastrophic failure of drivetrain) the car was no longer under warranty and total repair cost around $11 000 can. This far exceeded the value of the car so the car could not be repaired nor re-sold. The failure pattern started to happen when mileage was approximately 110,000 miles.
The vehicle had the engine replaced under Hyundai recall. What a fiasco. Within 6 months the fuel gauge starts intermittently work. Then the vehicle completely dies, diagnosis calls to have fuel pump replaced. Next 3 months the vehicle while driving losses power having to pull over to the side of the road. Thank god vehicle started and able to drive home, while the vehicle would loose power, then regaining it once took foot off gas pedal and applying pressure to again. That night find the rear brake light illuminated, went out stepped on brake pedal and went off. Another time console light would illuminate while driving no reasoning. The vehicle lastly killed the battery in the driveway. Had aaa tow to mechanic who now states the alternator needs to be replaced. After a few day not hearing back from mechanic, I call. He stating now the vehicle has electrical problems and it takes time. I will keep you posted. Hyundai has many major issues and should be held accountable, its a safety issue to the driver and general public.
Original report: 1/28/22 to Hyundaiusa problem with car started day after alignment. First noticed (while going up driveway) pressing accelerator did nothing - press again then ok. Got out to open gate, noticed brake lights on. Later (after dark), came out and brake lights on. Driving home noticed esc light on - esc off button had no effect. I found this exact description on "carcomplaints. Com" from 2019 and it references recall #136. Next day I cranked the car, and the "esc off" indicator came on. I was then able to turn off with the esc off button. Update: 1/29/22 next day same issue with brake light. Able to reset esc light but it came back on after driving about 15 miles. I noticed that the issue with the sudden deceleration occurred while going 55 mph. It happened about 3 times in the 5 mile return trip. Releasing the accelerator pedal then pressing again provided acceleration. When I got out of the car, the brake light remained on. Update 1/30/22 the esc light reset itself automatically when I cranked the car. While warming up the car in the garage, the brake light came on and I tapped the brake to turn off. This happened 4 times. I was pulling out of a side road onto a busy road with limited sight of oncoming traffic. As I started out, the acceleration died, and a car came around the curve/hill. I managed to release the accelerator and re-apply and got out of the driver’s way – he was able to slow down enough to avoid an accident. Issue happened several times while driving to my destination. A few minutes after going inside, the car security horn started sounding. I used the remote to turn off. I went back in, and it started blowing again. I pulled the fuse for the horn from under the hood. The esc light did not come back on during this trip but the brake light did numerous times. My research found that the brake light switch has been blamed for some of these issues. But a faulty brake light switch would prevent engaging gear shift.
About 1 month after I bought this vehicle, late December 2021, a warning light came on the hybrid screen, it read "hybrid system warning! safely stop and do not drive!" the accelerator was not working I pulled over and turned the vehicle off. I waited a couple minutes and restarted it up again and went on my merry way. About a month later it happened again!! it's happened about every 5 weeks until June 16th at about 5pm, it now permanently chimes and beeps with the hybrid screen warning me of the same, my foot brake goes to the bottom and makes a grinding noise. I am not able to drive it more than 100 yards or so then the accelerator fails again. I owned a mechanic shop and I know my brakes are fine, there has to be something wrong with the brake pumps/master cylinder, the brake fluid reservoir is full and the brakes electrical components make a horrible noise when I depress the foot pedal, I've read on Hyundai forum on-line, that this has happened to various others, its happened on the freeway while I was going about 70mph!! it's happened on busy city streets with 45mph speed limits. Hyundai doesn't want to take any responsibility for it! what can I do? the dealer wants $200 to have it checked with no guarantee that they'll find the problem. Thank you armando lopez 415-424-5831.
The cars engine burn oil very quickly and runs improperly. The car jerks when attempting to accelerate normally and deaccelerates when driving at normal speeds which can cause an accident with ongoing traffic.
The VIN number for this car is 5npec4ac1ch313689. "check engine" light was on and the car could not pass the inspection. We took the car to the mechanics and they found out " leak from fuel pump module" (please refer to the mechanics report for details) . Due to the safety concern, we have to fix it right away out of our own pocket. This particular VIN number is not included in the mhtsa 18v934000. We are requesting this VIN number to be added in the recall id 18v934000.
I started the car and immediately got a chiming sound with an error message "hybrid system warning! safety stop and do not drive" brake light also came on. I put the in drive and car would not accelerate past 15 mph and the brakes did not engage. I turned the car off and the message reset. Same issue occured about a month ago but the dealership could not replicate the problem.
The car hesitates when excelerating. The car has had this problem since I purchased the vehicle. I have reported to the hyuandai dealership within in a few days of purchasing it. They told me it was normal. It has been in and out of the dealership many times and they finally told me ithey installed the knock sensor device which helped for a short time but it’s gotten worse. It hesitates so bad at times I almost got struck from the side because my car got stuck in the middle of the road because it wouldn’t go.
I was in motion on the interstate and service engine light popped on and it was told it ended up being the camshaft. On my way to shop the next day my car cut off on the interstate and everything worked but car would not crank. Was told it was engine. I had no warning and yes my oil had been changed.
I took the affected vehicle to the dealer and they advised they did not have the tool to check the engine connecting rod. The vehicle had a dead battery and the dealer did some other work on the vehicle including a tune up and fuel induction and replaced a leaking valve cover gasket . The cost was $1009. 01 the repairs were done under the name of [xxx] ,the original owner. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).
2012 Hyundai Sonata on may 8,2020 Hyundai replaced my engine due to a recall . On August 18,2020 I had complained about the smell of gas that I smelled in my car . They inspected my vehicle and said it was fine . But every so often I kept smelling gas inside my car but no engine light or any light turned on and plus I thought it was fine since Hyundai inspected my car but February 4, 2021 I was parked with my vehicle running and the fuel smell started getting worse , entering my vehicle through the air vent. My vehicle would smell like gas even when it was turned off . So I turned my car off and I heard loud boiling bubble noises inside my car which is strange. I waited a few minutes turned my car on and then my thermostat maxed out all the way to hot so I shut my car off . I callled Hyundai & took my car to the palm springs dealership and they inspected it and told me that it's the high pressure fuel pipe . My vehicle is still at the dealership because I can't afford $1000. 00 to pay for something that's a recall. Especially since I complained about the gas smell on August 2020 . Also my right tail light is completely out . I replaced the bulbs multiple times but it ended up burning out . The wires are burnt and melted. This is car is nothing but problems .
As I was pulling out into traffic, the throttle went unresponsive. I pumped the accelerator three or four times and the vehicle lurched forward then begin driving normally. There was no "check engine " or other warning. I took the car into the dealer and they hooked it to a obd and drove it, to no avail. Has therein a any report of this problem by other oweners???.
I had a very scary incident Friday night, 12/18/20 about 8:30pm. I was about to merge onto the 5 fwy north to go home, and as I am coming out of the turn, and accelerating to anticipate the flow of traffic, I see a big rig in my rear view mirror in the distance. Naturally, I step on the gas to punch it, to give myself and the rig plenty of distance as to not collide. My car revved up and decelerates to about 2mph . I panicked and managed to coast the car to the shoulder as far right as I could and the rig barrels down past me. I was afraid to completely stop on the shoulder of the fwy, and the car lasted long enough to coast to the next exit. I am able to continue steering my car close to the shoulder at a crawling pace, and turned on my hazard lights. I had people mad behind me, but I could not speed up. I managed to coast to the nearest exit, come down the ramp, and stop briefly with just enough momentum to steer left onto telegraph in commerce, and my car completely dies in the first lane. This is the second time my car just dies on me while I am driving! first time was three years ago in December 2017 . The car had initially died while making a left turn. However, after turning the car off and waiting a few minutes, I was able to turn the car on and drive no more than 30 mph to the same downey Hyundai. The issue was under full warranty and repaired, but now a second time? worse yet, this happened while excelerating onto the freeway. I don't want to drive around in a car that has repeated recalls for various issues. I also don't want to worry of my car dying on me a third time. My Sonata is currently at downey Hyundai and they have started diagnostics and will have a better reading as to what happened. I have lost all confidence in this vehicle and worried for my safety and that of any passengers I may have with me.
The catalyst conversion is not working right I have change it and it still have gas smells come into the car.
Fuel is leaking from vehicles fuel rail on line going to injectors. Unsafe to drive. ## #vpic# 1 - check digit (9th position) does not calculate properly; 2 - VIN corrected, error in one position; 14 - unable to provide information for all the characters in the VIN. #vpic#.
I had a recall done on my Hyundai Sonata 2012 for the fuel pipe. I took it in to the Hyundai dealership in richland hills about a year ago, before covid19 I believe because I don't recall wearing a mask. They were extremely rude to me at the Hyundai dealership so I left there without knowing if there was a problem or not with my car. Now a few months ago I received another recall for the same issue an they said my fuel pipe needs to be replaced but aren't honoring the recall and are saying I must pay for the fuel pipe myself. ## #vpic# 1 - check digit (9th position) does not calculate properly #vpic#.
