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 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.

Ignition coil failure. Causing misfires and rough idle. Misfire initially found in cylinder 2 when check engine light illuminated and check with an OBD II reader. Swapped the cylinder 1 ignition coil with cylinder 2. Check engine light returned the next day with the same signs. Check engine light and rough idle. OND II code scanner now says misfire in cylinder 1. The rough idle makes for slow acceleration until above 20mph.

The oil level burns down to next to nothing approximately every 2 months, with no oil light warning or engine light. However, the engine light does periodically come on but shuts down itself before able to get it checked. The same issues occured with my son's 2017 hyundai which caused the engine to blow and catch fire. His was recalled and repaired. His was a different model. The oil burn on my car has occurred at least 3 times. The steering feels as though it is grinding at lower speeds an makes parking difficult as well. Both of these issues are most concerning.

The cars just stops running as you are driving. It's happened multiple times. We've changed the crankshaft sensor & cleaned the fuel system. We saw these remedies online as multiple people are having this same problem with their Hyundai.

The contact owns a 2017 Hyundai Elantra. The contact stated while driving 60 MPH, the vehicle stalled. The contact was able to veer to the side of the road. The check engine warning light was illuminated. The vehicle failed to restart and was towed to an independent mechanic, where the contact was informed that the engine pin in the crankshaft might have failed. The mechanic informed the contact that the engine needed to be taken apart for a definitive diagnostic test. The dealer was notified of the failure and informed the contact that the VIN was not under recall. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 88,000.

Was driving my car noticed that it was running a little rough and took it in for an oil change thinking maybe it was being a little weird because of that. I religious have my oil changed routinely. The gentleman changing my oil told me there was oil in the engine. Went to Hyundai and they did a diagnostics and told me that something had come off in the engine and clocked the oil gallery not allowing oil to flow through engine and power train. Was told it would be a $9000 engine replacement. I only have 93000 thousand miles on it still owe 3000 on it. Hyundai knows that their engines have been having issues. Salesman at Hyundai was trying to force me to buy a new car because of this issue. he was only going to give me 2500 on my car but told me if it had been in perfect condition then he would've 6000. This is not something I did to my engine it was something that came off in the engine and blocked the flow of oil

Hyundai claims its engines have a 100,000-mile warranty, but my Elantra 2017 engine blew up/ broke down just after 890200. Therefore, I called the Hyundai corporate office to fix my car. I also approached local Hyundai dealers at Jaining Road Hartford, Connecticut, but they refused to resolve my problem and denied replacing my car engine. I have no choice but to fix my car. I filed my complaint to Hyundai case no. [XXX], but Hyundai is not ready to resolve this issue. I have spent $4000 from my pocket to put my car on the road. I am requesting for the reimbursement. I have all the repaired bills and invoices. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The vehicle has about 136,000 miles and was driving when the engine just started knocking. There were no engine warning lights or any other indications there might be an issue. We Towed the vehicle to the dealer, and they advised that it needs a new engine. We are the original owners and maintained the vehicle with regular service and oil changes.

All four engine coils blew before 60,000 miles. The car was being used and maintained properly and there were no associated engine or spark plug defects noted. However, all four original engine coils failed and had to be replaced.

Original catastrophic engine failure in Sept. of 2022 while exiting the highway, was able to safely leave roadway. Determined that the motor had suffered symptoms shared with models related to Recall 203. Hyundai honored "goodwill" repair, but the repaired motor began suffering substantial and sustained loss of power with evidence of cylinder scoring 1 year/20,000 miles after replacement. Secondary incident occurred while merging onto highway and required evasive maneuver to avoid collision. Car is now parked and cannot be driven due to inability to operate safely on the road. Summary of events, related correspondence to repair, goodwill repair sheet, and original purchase documentation attached.

The engine failed without warning! The car stalled and could not be started again. There were no warning lights or indicators that the engine was having problems. The car had fresh oil and luckily I was just completing the safety check after an oil change. Had I been on the road, this could've been dangerous. The Hyundai dealership noted a seized engine with no further explanation without an extra $1000 charge. It will cost $10,000 to replace the engine that was well taken care of and only had 106, 748 miles on it.

Our Hyundai Elantra Se 2017, engine blown. Started with knocking sound and when we stopped on the side of the highway it powered down. We have been told that unfortunately so many of hyundai's vehicle engines have been super problematic within the last decade. We were stranded on vacation. Had to pay for towing twice and a rental car to get back to North Carolina because we had to get back to work. We also have had to pay to diagnose the vehicle twice. We had the issue diagnosed with an independent service center Tuffys Auto in St. Johns Florida and now it currently is at Hyundai in St. Augustine. We have been without our vehicle for over a month and with the trending problems with these engines we shouldnt have to come out of pocket to fix it. Hyundai corporate has not been helpful at all even though we have had a case manager for over a month and they havent given us any info.

The vehicle engine is burning oil. I found my oil pan having little to no oil and having a burnt smell to it and only 70,000 miles on the odometer. Hyundai made me pay for to have a combustion cleaning to help with the issue and would not cover it! This could have had my car blow up having no oil

I've heard that 2017 Hyundai Engines have had some recalls and looking online at others with these vehicles also experiencing same problems. Car only has 82,000 miles and now cutting off in the middle of driving under 1500 RPMs also shaking until it cuts off. Seems these cars engine warranty should cover the attached repairs as we've always done excellent service on these vehicles. I'm trying to see if there is anything I can do as we now have a $3500 repair and have to get a rental car in order to get to work.
