About 4 weeks ago (mid-May) I was driving in stop and go traffic on a major highway. My car is a 2018 Hyundai Elantra, manual transmission. After about 30 minutes of this, the car started to just cut out, the engine cut out when I was changing gears. It did this about 6 times on my drive home. I noticed that when the rev meter got below 1, the engine would just stall out, so I tried to give it gas to keep the revs up. In addition, the engine was making a knocking sound. I took it to my mechanic's the next day and when he heard the sound, he said it needs a new engine. He has had a few customer's with similar issues with their Hyundais. He told me to tow it to the dealer and they would help me get the engine replaced. That same day, I had it towed to a dealer nearby. They charged me $195 for a diagnostic and said it needed new spark plugs and replaced cylinder 1 coil, which they did. ($900) I picked it up, but I could tell it still wasn't right. The mechanic assured me he fixed it. However, they also told me the "check engine" light was on (it wasn't). When I was driving it, it started to stall again when I was changing gears. I brought it back to the dealer, he told me his mechanic had trouble getting it into reverse, there was a problem with the clutch. He would need to "tear down the transmission" for $2,000 and even then, he wouldn't know what the problem was. This just didn't feel right--I got the impression they didn't know what they were doing and that this mechanic couldn't even drive stick. I took it back to my own mechanic who couldn't find the problem. He told me to drive it around and when it makes the sound/cuts off, to bring it back. I drove it home--today--and the knocking sound started after 15 minutes. I recorded it and texted it to my mechanic. He called me and said "it's the engine. the dealership mis-diagnosed your problem and overcharged you." I called a different dealer, got an appointment for next week and must play the $200 diagnostic.

May 24 2024, while driving on Interstate95 at approx 70mph, I experienced catastrophic engine failure, with metal shards and screws shooting out, oil spewing, and smoke billowing everywhere. Loss of control of vehicle and nearly hit by passersby while trying to guide vehicle to swale. There were absolutely no warning lights or signals, and vehicle had just been serviced at Hyundai dealership at 77k miles (odometer reading 81k at time of incident). Independent mechanic diagnosed engine failure, hole in block, and provided attached photos. Vehicle was towed to Wallace Hyundai, in Ft Pierce, where it awaits dealer mechanical inspection.

I was driving about 45 mph when the car just turned off the first time. I was able to put it in neutral and start it back up to get to the side of the road and it died on me again. I was about 30 feet from my destination at this point so I got it where I was going and turned it off. When I turned it back on it was making a terrible knocking/grinding noise. It didn-??t have a drop of oil in it (about a thousand miles after my last oil change mind you) so I put oil in it and started it again and the sound quit. I went to drive it and it died before I could accelerate to a decent speed, got it cranked and rolling again and it slowly got up to 40 mph, but the second I started to slow down again it would die. So I had it towed to my mechanic who at first thought it was because the timing chain had a lot of slack in it, assuming it jumped time so he changed that, but it was still dying. He ended up finding the cause to be the exhaust cam sprocket? I-??ve never heard of this before but I do know that ever since I bought the car 3 years ago it never felt like it would get up and go whenever I hit the gas. Since I picked it up from being fixed, this thing zoom zooms everywhere now! But it is still using an ungodly amount of oil between oil changes.

The contact owns a 2018 Hyundai Elantra. The contact stated that while driving at 70 MPH, the vehicle made an abnormally loud popping sound. Two other drivers alerted the contact that flames were coming from underneath the vehicle. The contact checked the rearview mirror and noticed smoke coming from the vehicle's rear end. The steering wheel then seized, and the vehicle lost motive power. The check engine and several other unknown warning lights were illuminated. The contact pulled over to the side of the road and exited the vehicle. No injuries were sustained, and no medical attention was received. The flames extinguished themselves. There were no police or fire department reports filed. The vehicle was towed to the dealer, where it was diagnosed with a seized crankshaft and determined that the engine needed to be replaced. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was 224,809.

Having issues in several instances the past few months, where my car abruptly stalled in highway traffic, again less than a month later while at a stop light, traffic built up, I became nervous an scared, finally after turning my car off an on several times I was able to get my car to stop stalling an drive away. Third instance has been the ammount of oil consumption my car is needing, I-??ve noticed an increase use of oil for my car I use as a daily driver just commuting to a from work, an a clicking/knocking sound, other instances was my car accelerated at high rates of speed on the freeway on its own. Only after smash the break button was I able to disengage the throttle. An now just recently my car is using up more an more oil an has developed a hard knock in the engine. Similar to other models that have been recalled for the same reason. Reading online has made it clear thousands an thousands of other people are having issues just like mine around the same mileage as me an other models that have had the problems

Unfortunately I bought a Hyundai Elantra sport brand new in 2018 i-??ve kept the maintenance even to this day the car currently at 147,300miles. However I started having issues at 30,000 miles check engine would go on the car with shake and stall and miss fires would occur frequently. Every time I took it to the dealer they reset the computer but never made an actual note of what was going on with the car. That dealership that I took it at the time was Universal Hyundai in Orlando, Florida. So now that I have 147,300 miles the same misfires are now catastrophic failures on the same cylinders, to add insult to injury I took it to a different dealer located in Sanford Fl so they can try to get willful engine replacement, and my claim was denied because I was out of warranty and over the mileage, the dealership new that I was both over mileage and out of warranty the second I brought the car in somehow I still get charged $213. It seems like no one can do anything about it cause Hyundai America made there decision to deny my claim. These cars are straight up trash my buddies Kia similar situation has made it to 150,000 before he had total engine failure engine seized up on him. To make things worse I-??m making payments on a car that-??s needs an engine replaced. I-??m never buying a car from Hyundai ever again they-??re straight garbage and now I have to purchase another vehicle. Thanks Hyundai America for making unreliable vehicles and then taking my $213 to just deny my claim despite having a perfect maintenance record. I hope people read this and realize what crooks you guys are. Side note Hyundai America refused to help, however when I threatened to contact the BBB to complaint about there product the customer service agent Ciani mentioned they will open up case as to why I-??m putting a complaint to the BBB, I don-??t know what the outcome of this will be but it-??s irrelevant I wouldn-??t take a free Hyundai even if it was given to me! You lost another customer for life!!!

My 2018 Hyundai Elantra went from 50 mph to 0 in seconds. I was able to coast to the side of the road. The engine shut off. The engine and oil lights came on. Car didnt turn over after that got it towed to my house and once there checkd the oil and the oil was completely empty. Received my last oil change on 1/31/2024 still had miles left over before getting another oil change. There was no warning or signal notifying of oil low or anything after speaking with service mechaninc they mentioned the engine being shot. There is not even 100,000 miles on this engine and it needs a new one. Contacted dealership they advised no recalls on this model. Hopefully adding another complaint can get the ball rolling so there can be a investigation.

I got this car like 5 months ago and after driving it for 2 months I had to get a new engine for 4500 dollars. There is no way it can go bad in 2 months. The car only had 52,000 miles on it and it went bad when it reached 54,000 miles. After fixing that it went bad again after 4 months. I was also told that Hyundai Elantras are known for their engine problems. It would be great if there is an engine recall on this car. I am not trying to sell this car but I was this car to be fixed. Thank you!

Our hyundai elantra 2018 car started with a knocking sound while we were driving and it got worse our of nowhere when we accelerated and suddenly did this throttling sound with a pop. The battery light came on, the engine light came on and suddenly our car engine turned off and we were able to go on the side of the street we were on. Fumes were coming out of the hood and oil began to leak. The car was not able to be turned on to move it. We have towed it to our home, our local mechanic told us it was the engine. It has 135,000 miles on it. We got it from the dealership about 5 years ago and had not had issues until suddenly our engine blew!

I was at work when my wife contacted me and informed me that the car has started to make a ticking noise (shared car mind you) upon acceleration and start up. This all started on 1/4/2024. Well I checked the oil level and it was a on the line of being on the low side so I changed the oil as I needed to anyways and topped it off. I went to start to the car and ticking again, well I called around as I'm not going to ignore any sort of noise and was able to get a lcoal mechinic to look at it the next day as my local Hyundai dealership didn't have any opening until Saturday (1/6/2024). The next day I'm on my way to drop the car off to see where the sound could be coming from and the car shuts off. There were no warning lights or anything of that matter until the car shut off. I had to pull off into a street off the road. We get the car towed to the mechanic and he gets back to me the next day and states the car had low oil and that is why the engine failed. Hyundai shame on you all for knowingly putting a terrible engine into your products and for also at least not giving us the time by having poor sensors.

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 repair shop in town said this was common in Hyundai's and after checking online I found out that this has been an issue for 6 years before my car was built so Hyundai KNOWINGLY put a defective motor in my car. I have 149,000 miles on it but I still had over a year left to pay on it. just to get it moving I accepted the 70% and 9/27/23 I received an email saying it was done. The same day I received another email saying that they were wrong and it needed another part but should be ready early October. 3 months later I still have no car. I had to use an old truck I have that gets half the mpg. I've been paying insurance and payments on a car I don't have and don't want back. A page on Facebook, Engine Failure Kia/Hyundai describes many people's frustration with the same issue. When most get their car back, the engine fails again. I drive 110 miles a day just for work and its freeway 95% of the drive. If I have to drive in rush hour and my engine fails again, it could be disastrous. I want the dealer to buy my car back with compensation for lost money. I should not be forced to drive something that is a proven hazard on the road. I can mail all pertaining documents if needed. I can't scan them.

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 came on detecting any issues.
