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.

Oil consumption. The engine eats oil and is now becoming a concern because timing is off. not to mention the numerous bills for other things going wrong now due to the oil consumption.

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.

The engine of my vehicle malfunctioned. It is available for inspection upon request, it will have to be towed. The problem put myself and others in danger as the car stopped as I was driving in the middle of a 3-lane highway in the far left lane. Others were put in danger as they had to swerve to avoid hitting me. That itself could have caused a chain collision as other vehicles in the middle lane were put in danger. I was also at risk to get rear ended as one might not notice that my speed has stopped increasing. I have already had it towed to a local Hyundai dealership and auto shop; both said it needs a new engine. Towing receipt is shown below. I had no warning lights on my dash prior to the engine failure. A battery light and check engine light appeared after I was able to safely pull to the side of the road and try to start the car again.

I'm having issues with my car and I don't feel safe riding in it. While driving it start to coast. If I make a turn it shuts down. I am having some of the same issues some elantra having but because the VIN# doesn't show a recall I'm penalize for having this car.

My 2017 Hyundai Elentra Sport engine failed with 127,000 miles on it. Hyundai had a class action lawsuit for many models that guaranteed engine replacement and extended the life of the warranty to 15 years/150,000 miles. Unfortunately, it is the same issue with my model. Oil consumption issues resulting in a Blown piston. Oil was changed a week prior. Preston Hyundai confirmed that it was a Rod failure in the second piston. Paid the diagnostic fee and they put in a “Good Will claim and it was denied within 30 minutes. Preston Hyundai still has not sent me a receipt detailing their diagnostic or a copy of the goodwill claim after multiple requests. I want the record of this because the class action lawsuit that ended up protecting owners many years later

Without any warning lamps coming on, the vehicle car stalled while driving on the highway. It randomly stalls constantly when turning corners, especially on left turns (odd?). The scariest thing that happened was it got stuck on the speed limit of 55-60 miles per hour and I couldn't brake or accelerate. This put my kids, other drivers, and my life at risk. On Father’s Day, while my husband was out with the kids the vehicle tried to accelerate on its own when he was at a stop. It happened multiple times as he tried to make it home. Then when he was in stop and go traffic, it got difficult for him to brake. The brakes started failing. What more can I say?

I bought my used Hyundai Elantra 20017 in July of 2022. It's at the shop again for the same thing. While driving, it will just shut off. In traffic. My son was with me a few times when this happened, almost causing accidents. It's in the shop, second time, for engine failure! This car is crap and needs a recall on the engine before someone/ people get hurt while they are driving it.

Loss of engine power, car shuts abruptly off while driving. increases the risk of a crash and death. Less than a year after I purchased my car from the dealer. My check engine light would turn on and off frequently. Secondary mechanics couldn’t diagnosis problem engine check would show unnecessary/ different codes. Car burns oil at a very fast rate. Shut of three times while driving yesterday on the LIE. I am scared for myself and my families safety. I can’t afford a new engine or car. Please help The 2017 Electra SE has many recalls for make and model. My vin isn’t under recall.

Since January 2024 I have had issues with my car starting due to low oil. I just had an oil change so I knew something was wrong. The repair shop stated there were no leaks and put more oil in and said that sometimes the car will not start if there is not enough oil. February 2024 and the car wont start again. Filled it with oil and took it to the shop again. They stated that the engine is eating the oil and to take it to the dealer for a test. Since then the car has turned off multiple time both while idling and while on the freeway. When you hit the gas it will not accelerate either. In the past I was able to turn the car off and back on again and it would work just fine but now it seems more frequent. Also, while driving when experiencing these issues I have had the stereo screen shut off and restarted by itself. At times the slippery when wet alert will also show on the dashboard which has been a sign for me that they car is going to act up so I turn it off right away and back on then it runs.

When I stop at stop signs or stop lights, the car will stall out. I have to turn off the car fully, turn it back on, and immediately step on the gas pedal in order to start the car up again. This was incredibly dangerous as the first few times this happened, the stoplights had turned green, but I could not move the car. I am also afraid that the car could potentially stall in the middle of driving. The engine light has turned on and the car was inspected by Hyundai and a third party auto shop. The third party auto shop informed me that they had seen multiple models of my car with the same issue. The car is available for inspection upon request.

The car randomly dies on de-acceleration. It gives no warning and I have seen online this is a known issue with this year/model. I have 55,000 miles on it, it's been regularly serviced. When I got to slow down then start to accelerate it shuts off. I've nearly been hit multiple times going to merge from a stop. It's very dangerous. I've replaced all 4 spark plugs, all 4 ignition coils, air filter, cabin filter, oil filter, PCV valve and I've only owned it 6 months. No engine light comes on and no reader is picking up any codes. I'm at a loss as to what causes this.
