I am the owner of a 2014 Hyundai Sonata. That car is 8 years old and has 69K miles on it. At no time did Hyundai Motor Company notify that my car was impacted by an engine failure recall. On November 10, 2022 the car was being driven. At no time did it give any potential warning, instead the car fully stopped while in motion at 25 mph. There was no warning, no lights appeared on the dashboard until the car had stalled itself out. When I called the local dealer where the car was purchased, I was promised a call back. That call never came. I was able to contact someone at corporate who did confirm the vin number of my car is on an engine recall. I was told to contact a local dealer to find someone to replace the recall alerts. Again the local SURESKY dealer cannot help me. …

I bought my car at 97k miles in June 2022. From the 2nd day of having it, my car was shaking horribly. I sent it back to the dealership they said the front motor mount was collapsed. They repaired it but said there is still shaking but they don't know why. About 2 months later, I get in with Universal Hyundai and they only say that I need my axels and spark plugs replaced along with the air filters. They do a balance and alignment on my car as well as an oil change. The balance and alignment was either not done properly or my car just needs it done super regularly. Not too long after while I'm driving out of a friend's neighborhood my car is in drive and I'm going around 5 mph, my car stops with all of the lights on. I turn my car off and back on and carefully drive it home. Also, my car key always gets locked up in the ignition. …

I am submitting this complaint regarding a serious safety issue involving my Hyundai Sonata. While driving under normal conditions, my vehicle suddenly entered a low-power ("limp") mode without warning. The vehicle would not accelerate beyond approximately 30-35 mph, creating a potentially hazardous situation in traffic. At the same time, the check engine light began blinking. The sudden loss of power significantly reduced my ability to maintain traffic speed and safely maneuver the vehicle. This condition could have increased the risk of a rear-end collision or other accident. I brought the vehicle to an authorized Hyundai dealership (Fred Beans Honda Of Abington PH# [phone]) for diagnosis. The dealership confirmed that the vehicle stored Diagnostic Trouble Code (DTC) P1326, related to the Knock Sensor Detection System (KSDS). …

I was driving down the road in my 2014 Hyundai Sonata Limited 2.0T, in the car with me was my two young children ages 1 & 2. We were driving normally when the car all of a sudden shut off and died in the middle of the road while ongoing traffic behind me. I was able to come to a safe stop and crank the car back up and move to the side of the road. When I cranked the car back up it began knocking and the engine shaking. I immediately turned the car off and got my children out of the vehicle and we waited for my fianc and a tow truck. Car has always had oil changes on time in the three years I owned it. Only had 125k miles. Oil was changed 1 week and a half prior to this incident. I only ran it 567 miles before my engine stalled. Thankful I was not rear ended with my babies in the back seat.

Car is leaking excessive oil all through the engine and other main components. Theta engines are faulty and leading to engine staling and then failure. My engine stalled once. Was throwing no dash lights or codes. Next time the car was cranked it started knocking, still not throwing any dash lights. Brought to Hyundai dealership. The manufacturer is refusing to fix the engine saying it was ran on to low on oil to often. I had my records of maintenance to prove other wise once I provided them Hyundai said no still then said no because they took pictures of the inside and it looks as if it was running low on oil. This engine seizing can result in fire and major safety hazards including death and Hyundai is taking no accountability.

i was coming around a bent and accelerated down a straightaway when the car shutdown and all dash lights came on. I had to quickly find a spot to pull over as I was losing momentum and it was hard to brake. I pulled on to the front yard of a residence as there was no road shoulder. The car was smoking and there was a distinct smell coming from it. Some of the car was still out over the road so traffic had to avoid it. There weren't streetlights and it was foggy at night. I used the emergency flashers. There was no warning before the problem took place as far as engine light or warning lights being on. I had the car towed. It is currently at a dealership. Dealership determined engine seizure after diagnosis.

On the dashboard showing " Hybrid system warning. Safely park and do not drive" sign while the vehicle is being driven and slowly loose its power till completely stall. After I turn off the engine and try to turn on again ,the "Ready" sign keeps blinking. I was twice stall by the exit of a freeway. It's very dangerous. I also found a few recalls related to this issue in the past.

I was driving at a higher rate of speed 50 MPH in the center of 3 laned road no warning or indicator lights were on in my vehicle when the engine without warning blew and stopped working. Again no check engine lights were on no warnings were given. It shut down and would no longer accelerate or drive. We almost caused several accidents as this was a very busy roadway.
