Car had check engine come on with No significant symptom. Mechanic said this code leads them to either timing chain, phasers, or piston valve all located in the engine. The car does not have much time at this point. It-??s very costly after just having changed all the oil gaskets from a leaky engine. Mechanic said it will suddenly get bad if left unpaired and could be dangerous for me while driving.

My car has been stalling and shaking for months on acceleration. This has put me in unsafe situations where vehicles are going very fast on the highway and I am going 20 miles under the speed limit, or I am accelerating to merge and my car fails to accelerate, or I'm on the regular road and my car slows to a crawl while people are coming in fast behind me. The Error Code is: Cylinder 3 misfire. Took it to the dealer, they said they couldn't find anything wrong with it because the light was not on, they updated the software, as soon as I drove home the problem came back. They still charged me $200 for service, even thought the vehicle is under powertrain warranty which covers the cylinder block head and all internal parts. Online research shows this is a common problem in 2017 Hyundai Elantras. Many tried replacing coils and spark plugs only for the problem to return again a few months later. One successful fix found the computer needed to be replaced with a new one.

November 1st, 2024 My husband and I were northbound on I71/75 at mile marker 160 while traveling in the high speed lane, doing 65 mph, when the car suddenly lost power, the check engine light immediately came on (NO prior) warnings. The car would not respond, had to coast to the side of road while traffic is whizzing past us at 65+ mph. The car at that point was DOA, lights would come on but motor would not respond. After many discussions with Hyundai corporate and sending them proof of eligibility for remaining factory warranty (window sticker information) that I was told in detail by the dealership representative. I was told emphatically that with it being a lease turn in that I was still eligible for all remaining warranties. Hyundai corporate says that even though I only have 88,000 ( odometer reading at purchase was 24,147) of a 10year/100,000 warranty on the engine. Hyundai corporate says that because I wasn't the original purchased that the warranty is null and void. I feel like there is something very wrong here when these warranties can be voided at the whim of the manufacturer. I have since had to purchase another vehicle in order to make it to the VA medical center for my husband and make it to the hospital for my cancer treatments.

The vehicle has been randomly shaking at idle since around 100,000 miles. There have now been a few instances where the engine will shake when decelerating. There are no warning lights, codes, or diagnostic readings that have given a solution for this. Around 145,000 miles the engine began to shake aggressively while driving, as I stopped and put the car in park the engine light, oil light, and battery light came on and then the entire system failed and the car shut off and could not be turned back on. This happened on a -??highway-?? CA-108. I was stranded in the middle of the road, during school traffic hours. I towed the car to the dealership where they said they couldn-??t replicate the concern but replaced the oil control valve. It has been 2 months since the repair, the vehicle is again starting to shake when decelerating. I now pull over when this happens though it typically stops within 45 seconds. I have seen the other Elantra engine recalls and feel as though mine fits the description.

Issue with engine burning oil after I passed 104000 miles. I had my oil changed just after 100000 with no issues and just before the 104000 mile mark my Elantra began to make a clicking noise and my oil light came on. I took it to get the oil changed and I was told I was completely out of oil. I began monitoring the issue every few days and after traveling about 300 miles in a day I rechecked the oil level and noticed a definite drop in level. I contacted the dealer and was told nothing could be done due to the fact it was over 60000 miles and there were no active recalls. There is an TSB posted for the issue already. As well as there are recalls for the 2014-2016 hyandai Elantras burning oil after 100000 miles.

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.

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
