Engine seized on the highway

- Lansing, MI, USA

3 months after the engine was replaced under extended manufacturer warranty the vehicle started shifting funny, took it to the dealership and was told the transmission was bad, then another person in service said the transmission wasn't bad and didn't need to be replaced and they couldn't find anything wrong (after waiting for 2+ weeks for the transmission to come in), then the car left us stranded on the side of the road and not running, took it back to the dealership and was told it's a bad catalytic converter and we had to pay $2000+ to replace it. They at this time blamed the engine issues on a bad alternator. Now the car has a check engine light again and is throwing the code permanently for the catalytic converter. No way that a HYBRID car that barely ever actually runs on the engine should need a new calaytic converter around the 100,000 mile point except for an engine malfunction, which was the case and that engine was replaced back in December. Hyundai says it's not related and sorry, you have to pay for everything.

HEV WARNING TURN OFF ENGINE CAR STARTED SHAKING while driving on the interstate gas pedal went to the floor car started making a loud noise from the engine I put car in park and it would not move for 45 minutes at a stop sign

- Navarre, FL, USA

Engine began having issues with stalling out around 70k Miles. Car was taken to the dealer and Tessa on for issue couldn-??t be diagnosed. Car then began again at 83k miles took it to a repair shop and the issue could not be pin pointed once again. I was informed that the engine would have to completely fail for the issue to be properly diagnosed. Engine completely failed at 100k miles from barring breaking while I was driving the vehicle with my children in the car. Vehicle had to be towed to a mechanic shop and later transferred to Hyundai of Cumming. This issue was then confirmed for engine failure due to barrings breaks and the oil not circulating through the engine. There were not any prior warnings signs such as a light on dashboard or smoke out of the exhaust. All car maintenance is documented and up to date. This is the same reasoning behind prior 2016 models failing and being recalled. Dealer is refusing to issue a goodwill repair that was recommended by Hyundai corporate.

Yesterday while driving my vehicle engine stalled and wouldn't go over 40 MPH, about 10 seconds later the engine would not go over 15 MPH.

- Atlanta, GA, USA

As I was driving on the highway at 65MPH, a sudden warning appeared on the dashboard that read, "CHECK HYBRID SYSTEM/TURN OFF ENGINE". Immediately after that, I noticed that my vehicle started behaving erratically, making it difficult to control. I stepped on the gas pedal expecting the car to pick up speed and move forward. Despite the pressure I applied, the car failed to accelerate, leaving me stuck in my current position. After nearly causing a severe accident on a busy interstate, I was able to safely pull my car over to the side of the road. After conducting extensive research, I discovered that the issue I am facing with my hybrid vehicle is actually quite common among Hyundai Sonata Hybrids. It's surprising to note that despite this problem's prevalence, no recall or common solution has been provided to address it. I am highly concerned that Hyundai has not taken any action to address this issue. I request an immediate resolution as I could have been severely injured or lost my life today!

I constantly have to purchase bottles of oil and put into the car in between oil changes. The oil burns so fast and the car does not give a low oil signal on the dash. This is a known issue because the dealer recommended I return in between the oil change for a free top off because Hyundai engines are known for burning oil. I spend extra money every 2 weeks buying oil.

Engine is experiencing excessive oil consumption. Vehicle was confirmed by dealership.

- Kyle, TX, USA

Was driving home when my car went into limp mode - couldn-??t pick up speed to keep up with the flow of traffic. This seems to be due to the car-??s engine knock sensor being triggered. It is impossible to get it to the dealer in a timely manner. We are having to wait half a month before it can even be diagnosed.

The contact immediately veered to the side of the road. The contact then noticed flames under the front end of the vehicle, near the engine location. There was no warning light illuminated. The contact stated that the fire was extinguished independently. There was no injury sustained. The contact stated that the vehicle was towed to her son-in-law's repair shop, where it remained. There was no police report filed. An unknown dealer was notified of the failure and informed the contact that a repair fee would be charged for the engine replacement. The vehicle was not diagnosed nor repaired. The contact related the failure to an unknown recall. The manufacturer was notified of the failure and advised the contact to take the vehicle to the dealer to be diagnosed. The failure mileage was approximately 108,000.

Bought the car on 08/20/2022. On 09/07/2022 we took the car back to Allen Turner because the engine light was flashing and the car would not go over a certain speed. There were metal shavings in the oil. It was throwing code P1326. They did an update on car and told me the cylinder walls were scored but the motor had a lifetime warranty no matter what happened to it. Every time we would have the oil changed, we would have to add 3 quarts of oil every 10-15 days. The vehicle stalled out at a very busy intersection nearly causing a wreck with my teenage daughter driving. Had it towed to dealership and they said it needed a new motor because it has one of the defective motors in it according to the VIN. Then they told me it was oil consumption and they could replace spark plugs and oil and it would be drivable but it would stall, it would break down and the motor will seize. It is only a matter of time. Hyundai will not honor the warranty on it because the motor is not seized up. The service manager told me to drive it until it seizes and then they would cover the engine replacement. The vehicle is not safe to operate. It is a safety hazard for anyone to drive. Hyundai will not stand behind their products when they already know it is defective.

09/16/2023: Engine caught fire arrived at work at 830am and left at 4pm. Went to fedex (5 min away from job) and noticed burning smell. Left fedex (was there less than a minute because I was dropping envelope in drop box) and noticed smoke coming from under hood. Drove about a block and while making a left turn I noticed more smoke coming from under the hood. Pulled back into job's parking lot (since it was close) and within 5 minutes the engine was in flames. Flames were extinguished, but car was no longer driveable. Insurance claim was filed and vehicle was deemed a total loss. Cause of engine fire is still undetermined per insurance company.

Excessive oil consumption. Failed the oil consumption test preformed by Hyundai multiple times. Hyundai performed full engine cleaning and still consumes an excessive amount of oil.

This vehicle and model have a defective engine; I have made several attempts since I purchased this vehicle from the dealership to have this issue corrected, and nothing has been done. This is a very common issue with this particular engine, and it is a well-known problem; there are several class action suits regarding this engine, and the manufacturers still have no resolution for it. The vehicle requires constant new oil in between oil changes and has been like that since new. The engine burns oil, and it is not going anywhere, nooen seems to know.

Car stalled check engine light came on took to auto zone said a engine problem

I keep having the same issue with this vehicle's fuel/propulsion system, power train, engine, cruise control. This vehicle is need it's fuel system cleaned now for a 3rd time in less then 2 years. I have done the high mileage maintenance on it as well. I drive the vehicle less than 5,000 miles a year. When I am driving the vehicle, it struggles to speed up, making me press on the gas repeatedly to get to the indicated speed limit. The vehicle does not slow down as it should when pressing on the brakes. I have to press repeatedly over and over and harder on the brakes in order for it to slow down. The vehicle jerks, speeds up without me pressing on the gas and sometimes it will not stop when prompted. I cannot put this vehicle on cruise control, because it speeds up and out of no where, it accelerates causing me to almost collide with another vehicle or object. Even when the vehicle is not in cruise control, the sudden jerks and acceleration puts me, my children and others in harm when it suddenly speeds up, jerks or will not stop in time. It makes a loud noise and jerks even when the car is in a resting position. It loses power, it speeds up when i need it to stay the same speed or slow down. I fear this vehicle is unsafe. I have reported these issues and a few more to the dealership who never responded, so I had to go over their heads, then finally I got a response from their Consumer Affairs' Department, as well as the BBB and they state because of the vehicle's age and/or mileage there is nothing they can do about it. Please help me. This is the only vehicle I have, and I am a single parent who cannot afford another vehicle. What is going on with this car? Why do I have to keep struggling to pay for something to get fixed and it is still not solved. Below, it ask for a date, but it is multiple dates, not just one. I have listed the first time it occurred. Thank you.

I just got my car out the shop on April 29th at a Hyundai dealer and on may 2nd was driving on highway my check engine came back on and my speed decreased on its own almost causing a wreck then my car would only go 20mph in a 70 mph zone I have contacted Hyundai they refuse to do anything

- Owensboro , KY, USA

The first time my engine light came on was about a month after I had purchased it. The dealership told me to go to autozone to see what it could be. Report said it could possible be an oil clog or oil change. I got an oil change and the light was off. Light came on an every now and then but the car was driving fine. I got another oil change at the recommended mileage. My car won-??t start now, I thought it was a battery issue so I took it in to a mechanic to have it looked at and they said I need a new engine.
