2018 Hyundai Elantra GT: engine knocking or ticking

Filed Oct 1, 2026 · Engine · CA

My 2018 Hyundai Elantra GT (2.0L Nu GDI engine) has completely shut off while driving on three separate occasions: approximately June 2, 2026 (first occurrence), June 23, 2026, and September 14, 2026. The stalls happened on the highway at highway speed, while pulling into a parking spot, and on a public road at a stoplight. Immediately before each stall, all dashboard warning lights illuminated, then the engine died without further warning, causing sudden loss of power steering and power brake assist and making the vehicle extremely difficult to steer and stop. The vehicle also consumes engine oil at an extreme rate: after a full oil fill, the dipstick showed no oil within about two weeks (documented on video, September 30, 2026). An independent repair shop serviced the vehicle four times in 2026 for the same unresolved problem ($1,322.48 total), documenting diagnostic codes P0017, P0341, and P0366 and noting no oil leaks; the June 23 and September 14 shop visits correspond to two of the stall dates. This engine family is covered under Hyundai's Engine II class action settlement (2014-2020 Elantra GT, Nu 2.0L GDI) for connecting rod bearing failures that cause stalling and engine seizure. The Hyundai dealer proposed a 1,000-mile oil consumption test requiring continued driving of the vehicle, which I declined as unsafe given the repeated sudden stalls with loss of steering and braking.

I've contacted Hyundai to try and do a recall repair on my Hyundai Elantra GT 2018 both through a local dealership (Planet Hyundai in Golden, CO) and Hyundai corporate. The engine is stalling and knocking very bad to the point where it's no longer drivable. It's burning oil non-stop and I am constantly adding oil to it. I'm getting pushback from Hyundai saying I never fixed the recall when I was actually not notified to begin with. I'm the 2nd owner of the car so if I was never notified, how can I be responsible for something I was never told about? Now they are saying this little sensor was supposed to help let you know there's a problem with the engine (sounds like a check engine light?). Hyundai has known about their engines being faulty for quite some time. I need this vehicle to get to and from my job as well as taking my grandson to multiple doctor's appointments each week because he has a disability (he's only [XXX] old). They need to take responsibility for this. Is there anything the federal safety agency can do? INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

When driving the car home from the store. The car started to vibrate, and no lights came on then then I got to a stop light and the car didn't want to go when i was pushing the gas pedal tried it a few times the check engine light came on and was flashing then the car went, and the engine light went off. Got back home and an hour later went to the car and the check engine light was on and it was vibrating and making a slight ticking noise. I am not sure what is going on with it. I change the sparkplugs a few months ago and get oil changes regularly never let things go past the needed time.

Engine, power train, malfunction changing my speed control. No warning lights, first ticking noise from engine then knocking loud noise from engine. Noticed ticking about 4 days ago at first, today on freeway going 60-70 mph just changed to loud knocking, immediately engine warning starts to flash on dash board then speed just drops from 60-70 mph to 35 mph almost got hit by trucker and another car . Under 90 day warranty still from dealership (27 days since purchased) no license plate yet but insured and registered. Read many complaints of the same problems from numerous of people having the exact same problem. Very dangerous when vehicle stops accelerating on a steep pass on hwy with heavy traffic, this was almost an accident report to dispatch but luckily I reacted fast enough to swerve to the side before hitting the vehicle behind me and missing 18 wheeler trying to get to the right shoulder because theirs no space on left just concrete dividers! To close for comfort I can imagine what really can happen to someone that can't react as quickly as I did. Feeling like a victim their is no way they were not aware of this problem that has happened to many others when it is coming from a Chrysler dealership after reading so many complaints and reviews. I wish I would of known before hand ✋️ I would of not even bothered but now this is what I'm dealing with instead of feeling safe and comfortable being in a reliable, gas efficient vehicle that I just purchased for $30,000 and my jeep as a down payment not happy with dealership nor product. Who do I look to, when insurance or dealership can't protect me from situations like this it's not fair to someone that's struggling day by day paycheck to paycheck and this happens and now on waiting list until December so dealership is able to take a look at it. This should be most definitely brought to attention!!!

We were driving the car and all of a sudden it would only go 30 mph and starting making a noise, pulled over and car would not go anymore. I took to a shop authorized from my carmax care program and it was diagnosed as rod bearings broken in the engine. This is a know issue with this model and Hyundia extended the warranty due to know issue. We were then advised to take to a dealer since a warranty issue, when it got there and they looked at it and the repair shop called them to tell them they broke it down to failure the dealer is now trying to charge me 8 hrs labor to look at. This is not a my issue , its a manufacture issue so I should not have to pay all this money to have same diagnostic I reported to Hyuandi headquarters and also reported the shop. Someone needs to fix this issue my case # with Hyundai is 20400619

Engine seized and turned off unexpectedly and would not restart for hours. When it did start up a few seconds later it turned off again without driving this time. The battery, gas and oil were fine. It is now very very noisy and undrivable. There was a light ticking prior, but nothing concerning or I haven't heard most cars do. Yes, available for inspection. I was very lucky I had hardly pulled out of my parking spot. If this had happened while driving in the street or freeway I could have caused an accident. It hasn't seized again, but I am not driving except to the dealer who said the engine needs to replaced and is not honoring the warranty. There was a recall on this model that stated what is doing now was the reason for the recall. They replaced some cable, but it did nothing for the issue. No warnings prior besides the light ticking which is a normal characteristic of Hyundais, and I experienced this first hand with my last Hyundai Elantra model, but it did not ever have issues.

On Thursday evening, 4/28/22, I noticed engine knocking, and engine died while driving. Checked oil, and there was no oil in the car. Added oil, drove car to work the following day. Still engine noise, and dying on freeway. I never had any "check engine" or "low oil" warning lights come on to aleart me of any issue. The car only has 57K miles on it. Took the car straight to the dealership, and they are saying I need a new engine since they found metalic pieces in the oil. I know therer are other Hyundai recalls and lawsuits for engine problems, but not for this year/model. Service center said they are filing the warranty paperwork with the AutoNation Gold Extended Warranty, and I should expect a call today 5/5/22 to find out the status. Not sure why they are not using the Hyundai Powertrain warranty. (2nd owner, should be 60K milkes)

The connecting rod bearing in cylinder 1 is bad and I noticed online alot of other models were listed with the same problem but not my model. My engine block needs to be replaced. Car has not been inspected by hyundai but just a licensed local mechanic because the dealerships said it would be months before they can look at it.
