2017 Hyundai Elantra

Drove my car yesterday when it stalled. I was able to start it again and pulled to the side of the highway. The engine was knocking loudly. I turned off the car and called a tow truck. When hyundai received my car they told me it was the rod bearings.they initially told me id be covered regardless of warranty as its a known issue. They called me late that day and told me they won't cover it since I'm 18,000 over the powertrain warrenty. This very problem has been recalled from 2013 upto 2019. However my car isn't listed. They told me ill need a new engine which costs $6000 for parts and labor. After researching im not the first this has happened to.

I noticed the car losing power (2017 Elantra) took it to my local mechanic and got a misfire code on coil 3. Replaced it and the next day took a long trip to New Jersey, the car stalled at low speed with the CEL on pulled to the side restarted the car and proceeded to drive the rest of the way. I felt unsafe as the engine felt like it was struggling. On the way back I decided to tow it back to NY. I drove it the next day to my mechanic and he said there were no stored codes, he drove it and said he could do nothing. I drove it the next day and the same problem happened, luckily on a side street. Took it back to him and made him drive it around for a 4 day period nothing happened. My son drove it and the same issue happened luckily on a side street. I then took it to the Hyundai dealer and they said they got a misfire code. They replaced the remaining coils, changed the engine coolant and cleaned the fuel injection system. Maybe me wait practically 2 weeks with no loaner. Drove the car and the same issue occurred. Again luckily on a side street. I called my mechanic and he said drive locally and if it happens to call him so he will hook up a scanner to get a code. Right in my neighborhood the same thing happened so I called him and he was unable to get a code, he thought it could be either cam or crankshaft sensor, he tried both and the stall occurred when he was driving, he then changed the MAP sensor and drove it for 30 minutes without an issue. I went away for 5 days and came back and drove the car which seemed fine, but the same problem happened. This is a dangerous problem and feel unsafe driving this car. It has only 46.000 miles on it. I have a case opened with corporate and waiting for them to contact me.

I bought the car 3 years ago and during the first year I had to replace an engine coil, a few months later Inhad to replace the other 5. On July 3rd I was driving on the highway with my family and while I was stopped in traffic I heard a slight whine and then a knocking sound coming from the engine. I then started driving again and felt the steering wheel lock up and the gas tighten up and I realized the car had shut off. I had to immediately veer off the highway to avoid hitting somebody and noticed that the electronics were working. I then restarted the car and drove home through local backroads where the car kept shutting off intermittantly. I then took my car to a mechanic who notified me there was sludge in the engine and he had 3 to 4 other customers he recently has seen this happen to in regards to Hyundai Elantra’s. I tried to contact the dealership who accused me of not taking care of my vehicle. I currently have an ope case with Hyundai corporate. From what I’ve seen online Hyundai is aware of these engine issues about piston knock and wngine sludge due to piston issues yet has not offered a recall or any type of customer assistance. The engine failure could have not only grievously injured my family but any other drivers I may have hit or been hit by due to this known engine issue.

On 6/22/21 I took my vehicle in to the dealer for a warranty repair. There was a misfire on the Number 3 engine coil. My vehicle was returned and one day later I had the same warning light go off on my car. I returned to the dealer on 6/30/21 and there they replaced the Number 2 engine coil. The dealership told me that previously Hyundai would replace all 4 coils because it is a known issue, however because of cost they began only replacing them as they went bad. He said "they will all go bad, it's just a matter of if they will still be under warranty" In my opinion, Hyundai should still be replacing all coils if it is a known issue. My car was nut running correctly and would not fully accelerate. This could definitely be a safety hazard.

Engine make a lot of noise when I started, I have a situation where the engine stall and have to come to an stop, I bought the car about 2 years ago I took to the mechanic and I been told that engine has a problem and needs to be replaced staying that he has seen this problems on several vehicles same as mine with the same kind of engine, I took to the dealer and they told me the same thing but they said they can do anything about it. I don't know what to do with something like this its practically a brand new car, I also contact manufacturer with no luck.

The contact owns a 2017 Hyundai Elantra. The contact stated while starting the vehicle, there was an abnormal sound coming from the engine compartment. The contact stated that there was no warning light illuminated. The vehicle was towed and diagnosed but not repaired. The manufacturer was informed of the failure but offered no assistance. The failure mileage was approximately 42,803.

Driving with no signs or dash lights came on to warning me of any issues. Car started acting like it was stalling out one morning parking it at work. Went to leave work had a very slight almost not noticeable knock sound went I started up. Car was acting like it was running harder then usually. Continued home and my car started seizing up and caused my car to stall completely out while driving on the interstate. I was a mile from home, started my car back up and continued to get somewhere safely and out of danger of the interstate. It stalled out multiple times before reaching my driveway. By then my car seized up and was making a loud knocking sound. I push the car into the garage and check the oil and there was no indication of any oil on my dip stick. Went ahead gave my car an oil change earlier then scheduled. 1.5 quarts of oil only came out and was low almost 4 quarts. No signs of leaking or using oil. No indication dash lights came on to warning me of this issue. With in 3000 mileage of my last oil change, I lost almost 4 quart of oil, no signs or lights and now I have a blown motor in my 5 year old car. This is a huge saftey concern of my, with no indication I had an issue and was stalling out on the interstate/while driving to reach a safe place to look at my car.

So my car has been randomly started doing this sputtering like I'm getting ready to run out of gas and feels like the car is going to shut off. Well I had a full tank of gas so I thought maybe the sparks plugs. Had them changed along with my oil. That does not seem to be the problem so once I get where I'm going and turn the car off it seems to not do it. But it will randomly happen. About every week or two and I don't know what the problem is. When I'm driving on the interstate and it happens I freak out thinking my car is going to shut off and I start to lose speed and everything and the OBD reader states that it is a misfire but that's not the case when I have brand new spark plugs in
