2018 HYUNDAI ELANTRA Engine Problems

I was driving on the highway early in the morning and my car would not accelerate and slowed down until stopped running. Then the check engine, check oil, and battery light came on after. I tried to restart the car and it would not do anything. I popped the hood to check the oil and there was no oil in the engine. My car was not due for any oil change until another 1000 miles. No notification for low oil. No sounds , no smoke, nothing I had to tow it to my house.

I noticed around 100,000 miles that my car was going through oil when I heard a ticking in the engine. I pulled over and checked and there was no oil on the dipstick. No warning lights or nothing. I just kept adding oil after that and thinking that I will never buy another Hyundai again but never thinking my engine would fail full of oil. In June of 2023 my car lost power just as I got off the freeway. Thankfully it happened just as I got out of rush hour traffic otherwise it could have caused an accident. I had it towed home and the repair shop said my engine failed. I had it towed to a dealer and they confirmed that the engine failed. After many email and phone discussions with the dealership and Hyundai, they said they would cover 50% and then 70% of the repairs. The...

WHILE DRIVING, HEARD A LOUD POP THEN SMOKE CAME FROM THE ENGINE. THE ELECTRICAL SYSTEM FLASHED THEN WENT OUT. A PASSER BY COMING FROM THE OPPOSITE DIRECTION STOPPED AND TOLD ME THAT MY CAR WAS ON FIRE. I GOT OUT AND THERE WAS A SMALL FIRE ON THE GROUNG UNDERNEITH MY CAR. THEN OPENED THE HOOD WHERE THERE WAS A SMALL FIRE BEHIND THE ENGINE. ANOTHER TRUCK PASSING BY HAD A FIRE ESTINGUISHER AND PUT THE FIRE OUT. THERE WAS OIL ALL OVER THE ROAD. CALLED A WRECKER SERVICE TO COME AND PICK IT UP. UPON DELIVERY OF MY VEHICLE, THERE WAS OIL ALL OVER THE WRECKER. I'M VERY LUCKY TO HAVE HAD SOMEONE COME BY TO PUT THE FIRE OUT. I COULD OF BEEN IN THE CAR AND BEEN BURNED. THE INSURANCE COMPANY HAS BEEN OUT AND DONE A FULL REPORT ON IT. THERE WERE NO WARNING LIGHT THAT...

MY 2018 HYUNDAI ELANTRA SHUTS OFF WHILE DRIVING. THE ENGINE AND OIL LIGHTS COME ON AND THE CAR WILL SHUT OFF ANYWHERE WHILE I AM DRIVING AS OF APRIL 02, 2023. I HAD TAKEN MY 2018 HYUNDAI ELANTRA TO THE DEALER TO HAVE THE CRANK SENSOR REPLACED AND THEY COMPLETED THE REPLACEMEMT TODAY, WEDNESDAY, AUGUST 09, 2023. NOW MY 2018 HYUNDAI SHUTS OFF MORE OFTEN THAN BEFORE. I WAS TOLD BY THE HYUNDAI CORPORATION OFFICE TO TAKE MY VEHICLE BACK TO THE DEALER AND INFORM THEM THAT MY 2018 HYUNDAI ELANTRA IS SHUTTING OFF MORE FEQUENTLY THAN BEFORE....AS OF TODAY, WEDNESDAY, AUGUST 09, 2023.

UNKNOWN- intermittently - multiple times a day for the last month the car starts making clicking noises like a card in the spokes of a bicycle. Mechanic could not find the cause. UNKNOWN- two times in 2 weeks- while making a turn my car stalled in the middle of an intersection, all the lights on the dash went on, and wouldn't start up again for a couple minutes. Then car starts and runs fine besides the intermittent clicking

Knocking coming from the engine, OIL in the engine, Oil pressure light came on. Was looked at by two private mechanics and the dealership and was told the engine was faulty and not to drive it. The engine needed to be replaced. Was denied replacement by corporate since it just passed the warranty and was told to go to the BBB if I didn’t like it.

First, the plastic around wheel wells began to come out, then other parts of underneath near the skid area at the front of car begin to drag. Eventually a lot of the plastic pulled away underneath the car taking some of the front bumper. Then the car ran hot and had zero fluid in the radiator even though I regularly have oil changed and fluids topped off. Now the air conditioner throws out hot air when it on. I’ve regularly had oil changed. After only 3500 miles of having oil changed my oil light would come and car stalls when I’m turning. This could get me hit and killed. I bought car from car max and took it back as I have Extended Warranty that I’m paying for. They told me I had to have an appointment nearly a month out. I told them car needed to be seen now,...

I noticed around 97k miles that car just died as I turned left out of a parking lot at low speed. Thought nothing of it at first maybe I hit the keys with my knee. Then it happened again at 101k and recurred consistantly always within 1000 miles of an oil change at the scheduled interval in the manual. Then at 117k it did it again but when I started the car it developed a loud knock. I got the car home and took it to my mechanic and they said that the engine would need replaced. This is incredibly dangerous as it happens while traveling at speed and you lose control of power steering and acceleration.

I purchased this car as a used car at CarMax in July 2022 and it drove fine for about 10,000 miles, but starting in February 2023, my engine started to misfire. The first misfire happened when I started my car. I was told by my local mechanic that I needed a new engine after a compression test was run. My engine misfired a 2nd time while I was merging on the highway and a third time while I was starting my car. I only have 68,975 original miles on my car. The first 2 misfires illuminated the check engine light and the third misfire illuminated the check engine light, the battery light and oil pressure light, however my mechanic didn't find any codes with my third misfire. My car regularly rough idles and has a delay when I accelerate as well.

ENGINE SHUT DOWN AND INOPERABLE. POSSESSION OF CAR LESS THAN 2 YEARS, DRIVEN TO COLLEGE, WORK, ETC.

The contact owns a 2018 Hyundai Elantra. The contact stated that while operating the vehicle, smoke and an oil leak coming from the engine compartment. The vehicle was towed to the local mechanic who diagnosed that the engine was faulty and needed to be replaced. The vehicle was not yet repaired. The manufacturer and local dealer were notified of the failure, but no assistance was provided. The failure mileage was 93,000.

I just started my drive and my car seems to have rebooted while I was driving. The whole ordeal only lasted a few seconds. Things I noticed: 1) The steering locked (Guessing the electronic controls were down) 2) A few telltales were triggered and then the instrument cluster went blank 3) A the same time, the infotainment system went blank. Both the instrument cluster and the Infotainment came back after a few seconds 4) The engine revved up a bit at some point This has never happened to me before. I suspect it may be because of a new build software that was flashed to fix a security issue with Hyundai cars but I'm not sure.

Engine internal parts failure causing the car the to become a danger to the occupants of the vehicle and to others on the road the 1.6 litter gdi Engine is known for having Engine problems but little is said about the 2018 tgdi 1.6 litter in the hyundai elantra sport having the same issues. I thought I was getting a safe car for my wife and my children I guess I was wrong. We are second owners of the car we bought it from carmax and we got the max care extended warranty they knew hyundai had engine problems sold us the car without revealing any information about the problems and the when the engine problems accrued they along with another actual hyundai dealer have done everything in their power not to help so I'm stuck paying $16,000 for a car that does not run. I am extremely disappointed in...

Engine seizes or stalls shutting off the car completely and randomly. This puts myself and passengers and other on the road at serious risk of injury or death due to not being able to maintain speed or control of vehicle. It is available for inspection upon request. It has been an ongoing issue since 2020 and the dealership has “fixed the issue” twice. It is not fixed as it keeps happening. They deny any further issues and claim they cannot replicate the issue. I drove it from the lot again today after they “fixed” it and had it shut off on my way home. There has not been a check engine light that comes on in the past however this time it did making today the first time the check engine light came on. The check engine light came on before the car shut off while driving home from dealership....

Engine is defective and using excessive amounts of oil and will eventually fail or seize resulting in catastrophic failure or leaving customer with a lemon that they still own on. Hyundai hasn't issued a recall for this make and model but should have. As a result, been forced to constantly check the oil levels, and oil must be added to the engine more frequently than even the owner’s manuals recommend. MALFUNCTION INDICATOR LAMP (ENGINE LIGHT) suddenly came on at 123K miles. When engine light appeared, customer checked oil level which revealed low/no oil. Engine oil pressure warning light fails to come on dashboard display. Oil change had been scheduled months in advance but not due until about another 770 miles. Customers must suffer through extremely long wait times often 3-4 months later for service appointment at dealership even just for an oil change. The customer also expected to leave vehicle...

I fill up my oil at regular service intervals. When i drive my car after 3500 miles if i turn the engine stalls. This is dangerous due to loss of power. This has happened multiple times.

ENGINE COMPLETLY STALLED WHILE DRIVING, WAS PARKING IN A PARKING GARAGE, AND WAS DRIVING UP ON AN INCLINE TO PARK AND MY CAR JUST STALLED AND ALL WARNING LIGHTS CAME ON. NO WARNING LIGHTS WERE PRESENT PRIOR TO, AND ALL POWER WAS STILL ON. I WAS STUCK IN THE MIDDLE OF THE LANE, BLOCKING CARS IN. I WAS ABLE TO TURN THE CAR OFF AND RESTART IT AND IT STARTED UP WITH NO WARNING LIGHTS AND AS IF NOTHING JUST HAPPENED. I DO NOT FEEL SAFE DRIVING THIS CAR AND WILL BE HAVING IT INSPECTED IMMEDIATELY

Without any warning, the vehicle suddenly shut off while driving in a very busy intersection. It was able to be started two times as we tried to get out of the way of other moving vehicles but it eventually had to be towed. There were no warning lights that appeared on the vehicle to give us any indication something was wrong. It was towed to the dealership and we were told that there was engine damage, the engine needed to be replace and that it would not be covered.

My daughter is in college in Tallahassee. About 4 months ago, she told me that when she presses the accelerator, the car doesn’t go as fast as it should. In July 2022, the car was serviced in Tallahassee at the dealership; however, none of this is reflected on the receipt. In November she came home to Palm Beach County, on her way back, she told me that she was having the same issue when she pressed the accelerator. She made it to Tallahassee and I had her take it to the dealership. The Service Manager called me and said she had gone over the recommended miles for an oil change and this may have caused damage to the engine; however, he decided to change her oil and spark plug which coated about $318. She drove the car for a few days and noticed a loud tapping noise; also, the car...

The engine suddenly started stalling at stop sign or red lights at random times and the engine immobilizer light came on along with check engine and oil light. This was dangerous when turning left at an intersection. Car would be fine after restarting the car. Other times the ESC malfunction light would show while driving and the engine would not accelerate properly on the highway and the engine would also start jerking at times. Dealer said they could not fix it as this was an intermittent issues and they could not reproduce the issue when given for repair. Dealer and company did not agree to do a complete check and replace sensors, etc.

My Elantra was taken by theft. Rear driver side door broken. Ignition harness torn apart and the car was driven away from my senior living home parking lot on July 23rd at 3 P.M. Police were called but car was taken off the lot before they arrived. I received call from police on July 27th that the car was in an impound lot in St. Paul. Drivers side front tire blown out, wheel severly damaged. Some body scratched in left rear. Front passenger seat badly stained. Other damage unknown.

The contact owns a 2018 Hyundai Elantra. The contact stated that while her son was driving at an undisclosed speed, there was a loud sound coming from underneath the vehicle with the check engine warning light illuminated. Additionally, there was smoke coming from the front end of the vehicle. Another driver alerted her son that there was a flash of flame coming from underneath the vehicle. The vehicle was towed to the dealer where it was determined that the engine needed to be replaced. The vehicle was not repaired and remained at the dealer. The manufacturer was made aware of the failure and a case was opened. The manufacturer informed her that the vehicle was out of warranty and offered to cover 60% of the repair cost. The failure mileage was approximately 70,000.

The car has a security vulnerability where the car is able to start without the key being present. Also, the engine will shutter randomly (car will shake) when in idle. This happens especially the first few minutes from a cold start.

My car will shut off as I’m driving it. I was going thru a busy intersection and my car turned off, I was in my car with my 3 babies traffic backed up and almost got slammed into. I had to get out and push my car to the side of the road. The check engine light started flashing then the whole dashboard started flicking

While driving lost acceleration, car stalled multiple times. No dash light on at all when this happens. Having to add oil to my engine between oil changes.

The contact owns a 2018 Hyundai Elantra. The contact stated while driving 35 MPH, she depressed the accelerator pedal and the vehicle began to jerk and shake from the front end. The vehicle also hesitated prior to responding to the accelerator pedal being depressed. The contact stated no warning light was illuminated. The failure had become a recurring failure. The contact had taken the vehicle to a local dealer however, the vehicle was not diagnosed or repaired. The manufacturer had been informed of the failure. The failure mileage was approximately 38,000.

While driving, the acceleration stopped working and loud clanging noises were heard in the engine. There were no warning lights, nothing. I was driving on a busy road and the lack of acceleration created a major safety hazard for me and the vehicles around me. I eventually pulled over and restarted the car. It happened three more times on the way home. I got the car to my local mechanic and he said that it was the engine and it needed to be replaced. He saw this many times before on this model and told me to bring it to the dealer. I had the car towed to the Hyundai dealer/service center in Milford, Connecticut. I am waiting for them to look at it. I know that this has happened to many others with a 2018 Elantra and I am very upset that the car failed.

Engine stalls while driving. No warning, intermitted full shut down of the engine. Can happen multiple times in a row, only making it a few hundred feet before stalling again. The only remedy is to put the car in park and start the engine again, however, that is not always easy to do when on the road, and the car can only drift and brake. It is not safe when the car stalls, especially in traffic -- can be dangerous to myself and others on the road if I am unable to pull the car over or get it to start up again on the interstate. I have been to a mechanic, and 2 dealerships who claim they cannot replicate the problem, and even when it stalled in the parking lot when I was leaving, there were no error codes on the computer. This being said, without a code or...

My husband was driving the car when all of a sudden it stalled during morning rush hour traffic. As traffic zipped by us he quickly put the car in neutral and started the car. When it turned back on the car made a loud knocking noise. He proceeded to drive back home where it stalled one more time. When he was getting close to the house the knocking noise got louder. He then called our local Hyundai dealership and they stated that they would not inspect the car for well over a week. We then had a mechanic come over the house to take a look at it. The mechanic stated that we didn’t have any oil left in the engine. Even though we had an oil change three months, the engine had burned through all of the oil. We bought oil to fill the engine but chose not to...

UNKNOWN - for the past several months, since my car hit the 70,000 mileage mark, my check engine light has come on while experiencing hard idling, delayed acceleration/power while driving - particularly on gradual inclines and hilly roads. I would suspect it has something to do with the power or fuel system. I have changed oil twice and had a diagnostic test done and mechanic is unable to pinpoint issue since it is not consistent.

Multiple events of engine shutoff while driving. This results in loss of power braking, power steering and any acceleration. This occurs both at highway and non-highway speeds. This is obviously a safety concern, as, until the engine is restarted, there is difficulty in safely manuevering the vehicle. The engine may or may not be immediately able to restart. This occurs with the vehicle in gear during normal driving conditions (IE, driving at a steady speed on flat road) This is accompanied by multiple CEL faults relating to CCV timing, engine misfire, etc. This was a known issue in prior engine revision (Theta 2.0L), and appears to be subject to a recall of the same engine (Nu 2.0L) in other models. This vehicle was taken to the local dealer and confirmed to need an engine replacement with a similar failure mechanism as the Theta 2.0L (failed lubrication of pistons resulting in...

I just purchased this car on may 10 2022 after only having it a week engine light came on.startes to loose power and shake really bad. Took to shop replaced spark plugs and some other .think that was just a week ago .now while driving to day car just cuts of now don't wants to start.no waring lights just died .wondering do I have a lemon.

At slow speeds car just shuts off engine. Starts back up but does it constantly. Also the engine lifters are starting to make noises like a clacking someone said it was a defective motor.

I've had several issues over the years with this vehicle but nothing too major but more so a nuisance. Such as the car hesitating when accelerating, light bulbs constantly burning out on the vehicle within less than a year of being replaced by myself , etc. It is now April 2022 and vehicle problems begin arising, I heard a weird noise coming from the engine (after much personal research learned this is a knocking sound). Which also happens to be the same issue from the prior year models. One day while out running errands the car just completely dies and goes into limp mode while I was turning onto a busy street (very dangerous). I drove it a very short distance back & forth to work a couple of times because thats as far as I felt going safety wise. The engine jerked forward one day but still continued to...

The vehicle was taken to the dealer, and the dealer replaced several unknown sensors; however, the failure recurred.

The manufacturer was not made aware of the failure. The failure mileage was 64,644.

Engine would randomly idle mild to very rough when started and would sometimes correct and sometimes not correct while driving. This would turn on the check engine light for a misfire on cylinder 4. All ignition coils were replaced, and same code would happen. Hyundai was aware of this being a widespread issue and did a software update (Tech Bulletin 90C042R1). The problem continued, but seemed the check engine light would not come on as soon as before the software upgrade. Took back to dealership and they said the ignition coils would need to be Hyundai brand, change cylinder 4 to OEM and still having the issue. Engine also burns about 1 quart of oil every 7000 miles and often has a rough idle, with very rough idle periodically. I feel this would put myself and others on the road in danger if the engine were to fail while driving...
