As I was driving to work Saturday 3/12/22, four blocks from my home my Sonata with 064,000 miles stalled. I was able to restart the engine twice after which it made a lot of noise and, according to my mechanic, locked up. The mechanic tried to rotate the motor from the crankshaft pulley bolt and no movement, locked up. We suspect the failure may be connecting rod bearings premature wear, as has caused engine damage in the Sonata Hybrid currently on Recall. How can we determine the cause of this failure, and request satisfaction from Hyundai?

While driving, the engine in my 2011 Hyundai Sonata hybrid with the 2.4 liter engine shut off without notice (depressing the gas pedal and zero power)! I found myself and family in a difficult and potentially deadly situation as the speed limit on this road was 55mph, a large heavy duty tri axle dump truck was bearing down on my coasting car and family. I had few options from a safety stand point and had to make a snap decision. There was not a berm to pull off the road to the right side without trying to make a crash stop into the wilderness, or try to coast to the next available side street to get off the main road. As the vehicles coasting speed decreased I was very lucky that the oncoming traffic had a small gap between a another truck and a car. With few options I had to to make a decision and decided to try and make it to the side street almost causing a potential head on accident with that traffic. We were very fortunate to make it off the main road to the side street where we were now stranded. As one would realize we were very shook up emotionally do to this flaw in this vehicle. After many hours of research I see that a class action law suit was settled in 2021 for this exact engine bearing failure which seizes the engine and is now closed. From a safety stand point, reliability stand point and documented stand point a safety recall should be implemented to hold Hyundai Motor Cars responsible for all repairs to correct this safety issue. Additionally the obvious potential for the crashes and death become very apparent unless corrective action is not taken.

Out of the blue, in the middle of driving, this car stopped working. This could have been a very dangerous situation. There was absolutely no warning. Apparently, there is a recall, but it has not been publicized by Hyundai. Why was the recall not registered with the NHTSA" What efforts have been made, IN EARNEST, by Hyundai to reach owners? What advertisements, social media posts, outreach by dealers have been made? How many letters has each owner been sent, and how clear and serious was the wording on these letters" We had no idea there may be an issue with the engine, as we never received a notification from Hyundai. We never even heard of the recall until the car died in the middle of driving it. It is very dangerous that this issue exists and that no earnest effort has been made to notify the public. Not only are drivers and passengers being put in serious danger by the lack of information about this potential engine failure/potential fire, other drivers and passengers are being put at risk by having these cars out on the road. NHTSA should be advocating for the following: 1. More robust, earnest outreach on the failure issue. 2. Hyundai needs to give an accounting of how many affected vehicles have been sold in the US and how many have participated in their barely advertised recall (in order to let you know the scope of vehicles still affected.) 3. Hyundai needs to replace these engines or get these dangerous cars off the road by providing reasonable trade in value for people to stop using these cars. 4. This recall must be registered with the NHTSA and owners need to be alerted.

While driving and making a turn lights on the dashboard flashed and car died had it towed to local auto shop. They told me the vehicle engine had seized and there was potentially a recall on the engine had it towed now to the dealer they said there wasn't a recall but could have an extended warranty they charged me $400 to have the engine taken apart and take pictures to send to Hyundai which then in turn denied the warranty due to sludge so I sent them the maintenance reports for the vehicle which has passed inspection every year of vehicle. Rented a car for 2 weeks then have since gone without a car because they denied the claim. Waited another week it is now been over 3 weeks at this point for them to tell me they denied it again I've only had the car eight months and bought it at a dealer not a private sale which it was serviced before I took the vehicle. Have now had been without a car for over a month and I'm out almost $1000 plus the vehicle for nothing. Why certain cars recalled of the same year and others not when there are this many complaints on the engine and probably many more not reported

- Dundalk, MD, USA

I was driving my 2011 Hyundai Sonata home from work when without warning my car started making a rattling noise and slowing down. I was able to get out of traffic and luckily maneuver my car into the parking lot of a mechanic before it completely shut down. I tried multiple times to restart it and it would not turn over. I started checking things under the hood and when checking my oil noticed it was completely empty. Where did all my oil go? After being inspected by the mechanic he notified me that my engine had seized up and that it is a known issue with this year and model. I then had it towed to the dealership where it is still sitting to be looked at. It-??s been a week of me being out of work due to not having a vehicle. When I asked about the known issue they stated that my VIN number is not listed as part of those affected. There were literally no warning lights until that morning when the engine light and oil light came on while I was coasting into the parking lot of the mechanic. If it would have been a busier part of the day I could have been in a serious accident. I am still without a vehicle waiting on the dealership to look at my car.

As I was driving the vehicle, I had just exited off of the highway and onto a ramp and as I tried to accelerate the speed back to the speed limit my vehicle made a knocking sound and stalled at about 40mph. It would not speed up and as I kept driving to attempt to get home we could hear different sounds coming from the engine. I made it home as the vehicle seemed to be ready to complete shut off but didn't. I took it into Hyundai and they said it could be the turbo, but were unsure. They state there are no recalls on the vehicle, but it seems that this is a common issue for others with the same vehicle. The engine is not good and I cannot drive my vehicle safely.
