Other Fuel System Problems of Hyundai Elantra - part 1

This has happened twice. I brought it to Hyundai in syracuse and they said they could not find a problem. The problem: while driving the car loses power, when pressing the gas pedal the car stops propelling forward. Safety: the car randomly loses power while driving. This could happen when pulling out onto a highway or railroad tracks etc. Problem been reproduced: it has not been reproduced by a dealer. It's happened twice randomly in the 2 years I've had the car. I did bring it to Hyundai in syracuse NY but they said they didn't find an issue. Inspection: Hyundai in syracuse NY checked the car for an issue. No police or insurance. Warning/messages: there were no messages or warnings before it lost power.

I have a 2018 Hyundai Elantra with about 155k miles. It has been consuming oil excessively and has developed serious drivability issues. If I try to accelerate even slightly harder than normal—especially above 2,000 rpm—it makes a metallic, chain-type rattling noise, loses power, and produces heavy smoke from the exhaust. The smoke sometimes continues even after shutting the engine off and restarting. Because of this, I’ve been avoiding rapid acceleration and slowly working up to highway speeds. The car also periodically shakes at idle, idles higher than normal at times, and the rpms will occasionally rise on their own. In the past it has stalled randomly, and sometimes it feels like the transmission is “stuck” and won’t shift properly. Despite all this, there are currently no check-engine codes. This is terrible and clearly there’s been lawsuits and other recalls regarding the same issue and same engine but nothing for mine? I am out of warranty and had no clue the amount of issues the car was going to have until last year and I’m screwed now, insurance doesn’t cover issues with the engine or transmission. Neither will Hyundai?! last year Hyundai performed a cvvt repair that cost about $6,000, which temporarily improved things, but the symptoms returned shortly afterward. When I brought it back, they said they couldn’t recreate the issue. The car is now out of warranty. Separately, the car was stolen two months ago due to the immobilization fault and tik toks videos and the police said it has been hundreds of these Elantras stolen and destroyd and the ignition and wiper control switch/harness were damaged, which still hasn’t been repaired.

My fuel pump comes up and my check engine light saying that it needs to be replaced when I fill up my car it automatically resets my mileage for aaa and trippy and it will tell me that I have no gas even though I just filled up or it will say I’m full when I know I’m empty so it’s not reliable. It comes and goes. And then for an electrical issue my car will randomly stop working and then like come back up and it was underneath the positive plug. There is a clip that someone had to extend because it was too short and causing electrical surges so it’s still a problem if I go over a bump it gets loose so that clip under the positive terminal I believe is loose and makes my car shut off in the middle of driving at once and then it came right back on.

I am reporting a recurring issue with my 2023 Hyundai Elantra where the low oil pressure warning light illuminates consistently during strong acceleration. This is accompanied by a distinct smoky odor from the vehicle. Based on my research into recall 23v-859, which addresses fire risks from a faulty electronic controller for the oil pump in the idle stop & go system, I believe my vehicle is experiencing a related or identical failure. The symptoms strongly suggest that the defective oil pump controller is malfunctioning under load, potentially leading to dangerous overheating and a short circuit.

The car keeps lagging on acceleration I had the throttle body checked and cleaned and they said it was fine I have been doing all maintenance required by manufacturer, but sometimes is lacking on the power loses acceleration, I see these model has a recall but when I entered my VIN number doesn't show up so I am concerned why is not covered as it could lead to my car been stalled in the middle of the highway, dealer wants 300 dollars just to take it in and usually they can't reproduce the issue , what should I do in this case, I dont want to wait until I have an accident for this to be checked thank you.

Vehicle issue description for NHTSA complaint: component/system failure: the engine of my 2013 Hyundai Elantra (VIN: [insert VIN]) completely failed at 51,000 miles. The alternator also failed and had to be replaced. There was a persistent smell of gasoline inside and outside the vehicle, creating a fire hazard. All components are available for inspection upon request. Safety risk: the engine failure left the vehicle completely inoperable. The gas smell created a serious fire hazard and caused me to experience health issues, requiring an er visit. The combination of engine malfunction, electrical issues, and fuel leaks posed a risk to my safety and the safety of others while driving. Confirmation by dealer / mechanic: independent mechanics inspected the vehicle and confirmed the engine failure and alternator issues. Multiple mechanics advised not to drive the car due to the fire hazard. The original selling dealer (larry h. Miller Toyota) inspected the car and acknowledged engine problems in writing on a business card. Inspection by manufacturer / others: Hyundai corporate has been notified, but they declined warranty coverage as the vehicle is a second-owner car and beyond the original warranty. The dealer has also been made aware of the engine failure. Warning lamps / symptoms: no warning lamps indicated imminent engine failure prior to the engine dying. The first symptoms were mechanical issues, gas smell, and eventual total engine failure. Alternator failure and repeated maintenance issues occurred within 8 months of purchase. Additional notes: vehicle purchased at 34,000 miles; engine failed at 51,000 miles. Independent repair receipts, er paperwork, are available to support the case.

When you accelerate & let off the gas pedal, the vehicle still accelerated for 2 seconds after you release the gas pedal. It is like there is a delay with drive by wire signal. This situation can cause rear end collisions & hard panic braking. Please recall this situation to prevent higher insurance cost & increased accidents!.

While driving on the freeway at normal highway speed, the vehicle experienced a sudden and catastrophic engine failure. The engine immediately lost power, and the vehicle shut down within seconds. There was no prior warning or opportunity to take corrective action. The vehicle became completely disabled and could not be driven. This occurred late at night with limited traffic, and I was lucky to be near a freeway exit. I was able to coast toward the exit, but the engine seized fully, resulting in total loss of propulsion and blocking the freeway exit ramp. Law enforcement had to assist due to the disabled vehicle creating a traffic obstruction and safety hazard. A tow truck was required to remove the vehicle because it could not be restarted or moved. Under normal traffic conditions, this sudden loss of engine power at freeway speed could have resulted in a serious, potentially fatal collision. The outcome depended on luck, timing, and location rather than any safety system functioning as intended. The engine was later diagnosed by an authorized Hyundai dealership as seized due to internal failure. Hyundai denied warranty coverage because a software safety campaign had not been completed prior to the failure, even though the failure occurred suddenly and without warning, leaving no opportunity to complete the campaign. However, at the time of the failure, the NHTSA recall lookup tool showed zero unrepaired recalls associated with this vehicle’s VIN. The campaign referenced by Hyundai is intended only to detect certain engine conditions and does not repair engine defects. In this case, the engine failed before any detection or warning could occur. The vehicle had just been refueled and was equipped with four brand-new tires, confirming it was being operated normally. This incident involved an unexpected and complete loss of engine power at freeway speed due to an apparent engine defect, presenting a serious safety risk to the driver and other motorists.

Has not yet been officially diagnosed by a dealer or independent service center, but while turning into a neighborhood at around 15-25 mph the car jerked and the engine suddenly stalled while I was still in the middle of the road. Thankfully I rolled into the neighborhood before an oncoming car made its way over, but it was close. The gas pedal no longer worked, and I had to restart the car. It only drove once more before shutting down and the engine will no longer turn over.

When driving at low speeds(20mph and under) vehicle stalls. It appears to happen at random. It makes driving pretty dangerous for other vehicles that would not be able to tell the vehicle has stalled and hit me at low speeds. All electrics stay on, there is no check engine light. The problem first appeared after ignition lock was broken, even before replaced it started stalls at low speeds, seems to possibly happen more after engine is warmed up.

During driving, vehicle displayed a system error indicating an issue with the hybrid system. The vehicle then immediately, and without warning, completely shut off and caused the driver to have to manually guide the vehicle to the side of the road without power assistance. The vehicle is available for inspection upon request, however we have taken it to the dealership who have inspected the vehicle but told us they could not find an issue, even though we clearly experienced on. The incident can easily be verified by our insurance company, who had to tow the vehicle. This incident put our safety at risk as it not only caused a sudden vehicle failure which could have further risked accident, but the driver also suffered heat stroke waiting for the tow truck. As stated earlier, the service center at the dealership could not reproduce or confirm the issue and have simply stated that the vehicle should just be driven as is. The vehicle has not been inspected by the manufacturer, police, or insurance representatives. I'd like to further note that this service station and dealership is called horne Hyundai and is located in apache junction, arizona. They have ignored this issue, gaslighted us, and left us with no option but to report them and this vehicle.

Fuel injectors failed at 43,000 miles and 66,000 miles with no warning. Car misfired and left me stranded.

Initial fault code: p0303 replaced all 4 spark plugs and all 4 ignition coils. The check engine light extinguished momentarily but returned, logging p0303 and a new p0301 replaced all 4 fuel injectors. Cel extinguished momentarily and then returned, logging p0303. Replaced the entire engine electrical harness. Concurrently, all related electrical components and connectors were meticulously cleaned with professional contact cleaner. Cel extinguished for significantly longer period of time, and then returned, re-logging p0303 and p0301. Thid suggested the ecu was "handshaking" with new components but re-logging the fault upon detecting the persistent core issue. A full compression test was performed. All cylinders reported results within specification. Using a borescope I inspected cylinder walls in piston tops. There was significant carbon residue buildup but nothing out of the ordinary for similar gdi engines. I still performed a pea gdi specific chemical cleaning. It was a a little smoother afterwards, but the misfire persisted and cel remained on. I also removed, cleaned, and tested common sensor faults, with no result. Also p0128 code and no start / electrical drain, and engine light started flashing numerous occasions had to stop the vehicle. I tried swapping the coils, but all that proved was that the coil was good, I did a power and ground test, it passed the connector had 12 plus volt power and a perfect resistance to static ground. The signal wire from the coil connector had perfect continuity to the ecu but had ol to chassis ground showing there was no short. A test light was used to see if anything was coming from the signal wire to the ignition coil and that test failed, there was no signal pulse. The diagnostic process has definitively proven a component-level failure inside the engine control unit. See attached file for more detailed information.

Bought a 2016 Elantra in 2020 with 44,000 miles on it and a clean repair/ maintenance history. Let me preface the rest of this by saying I am an ase certified mechanic of 15 years who has been in the industry even longer. The first major issues I incurred with the vehicle happened approximately one year after purchase. The lifters started tapping and not long afterwards (about a week) I had a total engine failure on my hands. I was almost killed by a passing semi truck that was merging on to the interstate but was luckily able to avoid it and get the car on the side of the interstate where I had it towed to ralph sellers Hyundai in baton rouge louisiana. Long story short , even though the second owner is entitled to a 5 year, 60,000 mile warranty, they made me pay for a new engine. Here we are only 19,000 miles later and the same issue is occurring; except this time due to the stress the failing engine is putting on the torque converter the transmission is now failing to do its job properly. I have been back to the dealership but they offered no help except lies (they told me my high pressure fuel pump was bad, this model doesn't even have one!!!!!) I fully intend to sue Hyundai of America unless some appeasement can be made. Do not ever buy a Hyundai, they are trash cars made to look nicer than they are. Additional details will reflect most recent incident with engine/transmission.

Drove my 2015 Hyundai Elantra on the coldest day of the year to an appointment. Car was fully warmed up. Pulled into a gas station to park and was going less than 3 mph, making a left hand turn into the space. Elantra suddenly accelerated hard and the car hit a cement pole, causing extensive front end damage. If car had full insurance coverage, it would have been a write off. Hood crumpled, radiator damaged, front grill broken, bent the engine bar in half. Significant damage but the air bag did not deploy. Had to have it towed home 35 miles. Damage was in the middle of the front of the car, so I was already in the parking space. No warning lights of any sort before this happened. Very dangerous and I would never buy another Hyundai. I bought this car brand new in 2015 and have had recalls taken care of (anti theft software one). Over the course of owning this car, other odd things have occurred as well, such as white smoke coming out of the engine upon acceleration, accelerated wear on the tires due to the back end, and engine will suddenly stop for no reason while driving (this happened twice) inferior product!.

Had to do 3 oil changes in a month had to change ignition coil that had been changed a month ago spark plugs were completely covered in oil was driving and it literally just stopped every time the oil would be checked it wouldn't be any on the dipstick.

My 2017 Elantra with 107,000 miles (it has a 100,000 mile powertrain warranty) on it has just experienced the same issue as all of the other Hyundais that have been recalled. I was driving on xmas evening 2024 and started hearing my engine making noises I had not heard before when excellerating but then they would go away. On my way home the check engine light went on for a couple of minutes but then went off and I was able to get home although the car did not seem to be riding well. The next day, the check engine light went on again and so I brought it in to my mechanic. He said that there were metal fragments/shavings in my oil that were clogging my engine, etc. He said that I need a new engine and said he had several other Elantras with the same issue and that I should take it to a Hyundai dealer because of all of their recalls/class action lawsuits which extend warrantees, etc. For the same exact issue. I was able to drive the car there but it was not a safe drive. Their assessment was basically that I need most of my powertrain replaced to the tune of $4100. 00 but once they get in there, it might be more extensive and end up having to be replaced. However, they did not say anything about the metal fragments and when I brought it up to them, they acted like they didn't see them. However, my mechanic (with no skin in the game) said they were all over the place in my car's oil. So, I am a little wary that they decided to skate that issue, since it is the basis for all of their class actions, etc. I'm kind of stuck, Hyundai has my car and it really isn't drivable. I've checked many Elantra forums and have seen that this is happening to many other 2017 hyundi Elantra se even though they have not yet been added to the recalls/class actions, etc. I really think that the Hyundai engine issue is more widespread than just the cars on the current list and I hope that this is looked into as it is extremely dangerous and comes on very quickly without warning.

Car keeps turning off every time I start it and won’t stay on.

The warning lamp (engine light) illuminated blinking on and off. Engine code p1327 read on the diagnostic check, riding on the expressway was a little uncomfortable, engine was losing power which is unsafe at high speeds. I’ve contacted the nearest Hyundai dealer and scheduled an appointment for the car repair. I take care of the car and any repairs for maintenance and I never have any problems whatsoever until day. After doing research Hyundai had or has a recall for my vehicle with the VIN number starting with kmh, for engine replacement and I want to know if Hyundai can fix this issue.

While driving vehicle the black nylon fuel line started spraying fuel over the top of the hot engine. At highway speed the passenger compartment filled up with gasoline fumes. Pulled over to open the hood and saw fuel streaming from the fuel line on top of engine. Vehicle was shut down, and aaa towing called to tow vehicle 85 miles from staugustine FL, to gainesville florida to Hyundai dealership of gainesville. The vehicle has been in the shop on [xxx], for repairs. This vehicle only has 44000 miles on it. Hyundai states that they don’t have the fuel line in the USA and had to order the part from korea. I was stranded 352 miles from my home. I called Hyundai corporate to notify them of this issue with the defective fuel line. They said there is no recall on this part, and not covered under the 10 year 100,000 mile warranty. They told me it’s going to cost me $1124. 26 for the repair. I almost lost my life potentially being barbecued in this vehicle, not to mention other innocent people getting hurt. I have owned many cars in my lifetime and this is the most dangerous vehicle I ever had. Potential to explode and catch fire while driving on expressway. I think NHTSA should look into this vehicles safety before other innocent people get killed. An extremely dangerous road hazard. Note this vehicle only has 44,000 miles and is maintained properly. Hyundai doesn’t care about safety, and their customers. When I purchased this vehicle they told me how safe it was and the best auto warranty in the world. Please look into this fuel line defect before someone gets severely injured or killed by fire. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

Fuel line on top of engine cracked spraying fuel on top of hot file:///var/mobile/library/sms/attachments/1f/15/4dc59d25-4f9e-41e5-a17e-a14f53b29de4/img_6793. Mov.

The soldering of the end cap in the engine fuel rail failed and allowed gas under pressure to leak out. Fuel sprayed out in the engine compartment and the smell was evident inside and outside of the vehicle while in operation. Not sure how it did not start an engine fire. Repairing was a simple task that I handled as this is the only vehicle available to me. Ordered a new fuel rail which was only available from a dealer without issue and completing the repair went without issue. Did not have anyone else look at the problem as once I figured out the problem, did not want to drive the car anywhere. I have the old fuel rail for anyone who needs to inspect it.

Have a raw fuel smell every time I park my car.

This has happened a couple of times where in the middle of driving, my car automatically shuts off, I can not turn my steering wheel I can not push the brakes, everything stops working. I have to wait till my car comes to a complete stop on its own, put the car in park, turn off the ignition, turn my keys and start my car again. Then it sometimes acts like there is no power to accelerate when I'm at a full stop. Rpms go crazy, but acceleration doesn't occur. No warnings have ever come up. I received an notice about a recall, but it's for 2019 Elantra and up. Mine is a 2018, but the issues for that recall is the same thing that is happening with my car. This is dangerous and can lead to serious repercussions or even death. Something needs to be done to fix this. I don't not have thousands of dollars to pay for an issue with the manufacturer.

I experienced an issue where I was driving the vehicle, and then a "hybrid system fault" message appeared on the driver information display followed by the complete loss of power. This made me have to pull over to the side of the road with no ability to accelerate out of the way of traffic to come to a stop. Once I was stopped I tuned off the vehicle and tried to turn it back on, but the vehicle would not respond so I attempted pressing the 12 volt battery reset button to the left of the steering wheel to see if this would allow me to turn the vehicle on and the car came back to life with no warning lights or messages and drove normally. This happened three more times over the course of ~1. 5 hrs on my way home on the highway. I understand that things happen, I just wish there was more warning before all power was cut and the vehicle went into limp mode as this left me in a dangerous situation. The vehicle has been dropped off at the dealer and is awaiting a new hybrid battery replacement under warranty.

Since January 2024 I have had issues with my car starting due to low oil. I just had an oil change so I knew something was wrong. The repair shop stated there were no leaks and put more oil in and said that sometimes the car will not start if there is not enough oil. February 2024 and the car wont start again. Filled it with oil and took it to the shop again. They stated that the engine is eating the oil and to take it to the dealer for a test. Since then the car has turned off multiple time both while idling and while on the freeway. When you hit the gas it will not accelerate either. In the past I was able to turn the car off and back on again and it would work just fine but now it seems more frequent. Also, while driving when experiencing these issues I have had the stereo screen shut off and restarted by itself. At times the slippery when wet alert will also show on the dashboard which has been a sign for me that they car is going to act up so I turn it off right away and back on then it runs.

Loss of engine power, car shuts abruptly off while driving. Increases the risk of a crash and death. Less than a year after I purchased my car from the dealer. My check engine light would turn on and off frequently. Secondary mechanics couldn’t diagnosis problem engine check would show unnecessary/ different codes. Car burns oil at a very fast rate. Shut of three times while driving yesterday on the lie. I am scared for myself and my families safety. I can’t afford a new engine or car. Please help the 2017 electra se has many recalls for make and model. My VIN isn’t under recall.

Having trouble with fuel pump. Have had many appts. With my mechanic. Has lost power while driving and had to have it towed in. Engine light stays on no matter sensors.

When gas is pressed (even to floor) in drive, vehicle stalls, does not accelerate. Then vehicle jerks into propulsion after revving. Other instances, at deceleration the car will jerk and shake to a stop. I have mentioned the problem at every scheduled maintenance.

Car will lose power and quit suddenly on the highway with no warning lights. It has happened twice in the last month on a trip both times. Light’s low beam randomly won’t turn on either but high beams work. Had it into the Hyundai dealership and another mechanic shop but cannot find the problem.

The positive battery terminal melted from an electrical issue and cannot be fixed due to the model and year of my car. The whole car has fully died and is not functional. My car is available for inspection. The car has only been inspected by a mechanic. The car would have trouble starting and staying on for the last 2 months or so and right before it died it was showing the steering wheel light for 2 days and then all the lights were blinking.

On December 28th I was parking in my parking spot outside my house, went to pull up 3 more inches in my parking spot when the vehicle accelerated at an extremely rapid speed, went over the high curb, up my front lawn into the tree in my front yard. It was a battle between the brake and the gas acceleration event. Then I put it gently in reverse, my car fled rapidly down into the parking lot at such a high rate of speed, I turned the wheel, my car hit 3 cars across the parking lot, shot across the parking lot, popped over that curb, went down an extremely steep hill, hit the cross street, went still in reverse over an island, wiped out two signs and crashed into a car in the middle of the 4 way stop and stopped. My insurance is blaming it on driver error like they are blaming thousands of drivers over the same experience, stating that I mistook the gas pedal instead of the brake and also stating that I did not attempt to brake, that is so far from the truth, you can look at the track marks on the ground and tell I was standing on the brake. What is being done about these awful scenerios. My car is currently in copart being assessed. My car was serviced at the Hyundai dealership ever since I purchased it, all the records are there and in my possession, I had low mileage, less than 48,000 miles and planned on holding onto the vehicle for at least 6 more years. Now my car is sabotaged, being blamed like 1,000 of other drivers over the car malfunctioning. There is a sensor for the throttle, a sensor for the gas accelerator that the computer control unit brain waits for the analytical data from both sensors and adds additional throttle to the situation. Once the car is turned off the entire system resets itself, so there is no evidence of high throttle, gas accelerators sticking and the driver is blamed. Since the insurance companies have insured these vehicles there is a lot at stake for these cases to be proven and for the Hyundai manufacturer as well.

I had to replace my Cadillac converter twice and it keeps messing up on my car and I have to keep replacing my headlight bulbs on my vehicle. They keep going bad and the vehicle tells me when the headlight bulbs is out, but I don’t replace the headlight bulbs, four times and the catalytic converter three times and my blindspot detection system and rear across traffic alert system keeps going out on my car and I done replaced it and recalibrated it six times already and there should be recalls for all this on the vehicle and my license plate lights keep blowing out on my car and placed those seven times all this need to be recalled for 2018 Hyundai Elantra and there is loud clicking noises from the steering wheel when I turn left to right on 2018 Hyundai Elantra that also needs to be recalled that’s a safety issue and I replaced my brakes six times and the rotors on my 2018 Hyundai Elantra and this is a big safety issue that needs to be recalled so they can get fixed so the customer owner, don’t have to keep pay for it.

For the past two weeks, the car has intermittently stalled out and the engine, oil, and battery lights come on. The dashboard electronics and radio stay on. When this happens, I have to put the car in park and turn it off, then turn it back on. It has restarted immediately each time and drives normally. It has stalled out multiple times in a day, but not everyday. I took it to my mechanic twice to pull an error code from the warning lights, but he could not. My safety and the safety of others were put at risk when it stalled out while I was deaccelerating on an exit ramp that merges with three other lanes. I could have been hit from behind by others exiting the interstate highway or hit on either side of my car from drivers switching lanes at that junction. It stalled out the same day in the middle of a roundabout, where drivers yield and merge at 30 mph. I've noticed that when it stalls out, I'm usually braking or the vehicle is turning. The car is currently at the mechanic, who has not yet been able to reproduce the stalling and warning lights, but he did pull a diagnostic trouble code: p010600; description: manifold absolute pressure/barometric pressure circuit range/performance. He's not sure if it's a faulty sensor or if something is causing the trouble code since the warning lights weren't on with the code. The car has not yet been inspected by the dealership or others.
