While driving normally on the highway I received the "Hybrid Safety Warning: Do Not Drive!" error. The engine began sputtering uncontrollably, the brakes weren't fully responsive and I lost power steering. Thankfully I was able to coast down the road and pull over. If this had happened in traffic I can't imagine an accident would not have happened. Not being able to brake safely or steering properly while your engine is sputtering out of control is terrifying and a MAJOR mistake in design and implementation.

While driving the vehicle the lights on the dash start to flash, stating that there is a Charging system warning. It says to pull over and not to drive. It becomes very difficult to brake, or steer, almost like the vehicle has lost power. It blew warm air and the check engine light also came on. This can be extremely dangerous if one was on the highway or at an intersection or any place where they needed to pull over to safety. My 12v battery was checked and found to be fine. I called multiple mechanics to come take a look at the vehicle and the codes that were read were P1B77, P1B96, P1B70, P0A0D. The 150 Amp fuse was said to be blown, and was replaced. Sometimes the car will start back up, and sometimes it won't. Currently, it's sitting in my yard. The engine and interior look pristine, but there is something going on with these vehicles that isn't being addressed. This car is dangerous and there are many, many, MANY people that I'm finding on Reddit, YouTube, and the Hyundai forums who are having the exact same issues. I unfortunately cannot afford to continue to keep hiring mechanics, nor to have it towed to the dealership, only for them to do what they are doing with countless other people. They do not seem to understand the issue either and are grasping at straws to replace expensive parts, only to have the issue reoccur. Something needs to be done about this before someone is killed.

The contact owns a 2014 Hyundai Sonata. The contact stated that while driving at an undisclosed speed, the vehicle made an abnormal sound.

The vehicle was towed to an independent mechanic, who informed the contact that the engine needed to be replaced. The vehicle was then towed to the dealer; however, the vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 124,000.

Complete engine failure while driving. Car completely shut off and will not restart. It did not give any warnings prior to happening. Also cruise control stopped working months prior to this engine failure. Took to mechanic and he stated there is recalls on this vehicle and need to turn it in. I have also received mail stating the same about recalls.

Unknown, my vehicle sounds like the valves are knocking. I've had my oil changed on time since I've own the vehicle. While driving, my car shuts off. I pulled over and started it again and 3 mins later it shuts back off. Now I cannot start my vehicle. It literally won't allow me to. And there's metal shavings all throughout my engine.

A week ago (June 5th) car had been running fine, then all of a sudden lost power. Wouldn-??t pick up speed, several warning lights came on and then it just died. Did hear a knocking noise right before it died. It is currently at dealership and was given a time frame of approximately 3 weeks to fully diagnose. This is obviously frustrating as I just got this car at end of March and it is being financed, so paying for a broke down car at this point! I hope that Hyundai manufacturer fixes this issue because it seems to be happening to quite a few people upon doing some research!

The engine seized while driving on the highway. The car is currently at the dealership. It started making gurgling noise and slowed down while driving. This happened in the middle of the road while driving, putting me and other drivers at safety. The dealership inspected the car and they said the engine seized. There is a recall and multiple complaints concerning this car. They have now said that they will not honor the recall and repair the car because I don't have all the oil change documents. I bought the car as a used car and have my documents since I have owned the car. They are taking care of the issue that is definitely manufacturing issues.

The engine locked up right as I pulled into my driveway. No warning lights or anything indicating there was a problem. I-??m lucky to have made it home when it happened. I know other Hyundais are being recalled for the same thing. Not sure why my year isn-??t being looked into

My car has been at the dealer since 5/3 which i had an appointment for the TXXI engine failure and fuel pump 227 recalls. I was driving my lights all came on and the car decelerated and wouldn't speed up anymore the steering wheel also got tight.i just got oil change at the end of March and haven't been any long distances. I was told 2 days later that my car was being diagnosed it is now 5/10 and I'm still being told my car is being diagnosed with absolutely no update, they also refuse to give me a rental car or provide a out of house rental... They are making me pay out of pocket for rentals then can only post for reimbursement which isn't guaranteed after the work is done but cannot give me any type of word on even when the diagnostic will be done. I asked if they have any order to diagnosing like is it in order he said no i said so someone can bring their car in after mine and get completed before for same thing just depending on which the technician decides to do the advisor said yes candidly. I've been calling for updates and have not received anything other than the diagnosis is still not done after 7 days. I'm paying for a car that i don't have access to and it's not being expedited in order. When i dropped the car off they said it would take 4 days tops with are they starting my car then not finishing.

On our way back home from a road trip, the Sonata lost horsepower and I was only able to drive at about 40 mph (on highway). Once we reached the next town, stopped at an AutoZone since the check engine light came on. Tested the issue and it looks like the car went into safe mode and there was an issue with engine oil consumption. Added more oil and continued our way home. We were stopping about every hour to "rest" the car for about 30 minutes and recheck oil levels. After the 30 minutes, we continued on our way home. Once we pulled up tp our home, the engine died. We were fortunate that it didn't happen on the road. We haven't been able to turn the car back on. It has been like this since July 2022. Sitting in our driveway. We have contacted the dealership where we purchased the car and they refuse to have the car towed to their location and they won't even look at our vehicle. Currently, our VIN is not coming up with the engine recall when I search it here but it looks like our vehicle is also affected by that recall. We did receive a notice previously.

Hello! I bought a car at an auction, it had the crankshaft bearings turned and it was knocking. I decided to repair it myself in my workshop. When I disassembled it, all the bearings and crankshaft necks were erased there (I kept all the details) the connecting rod on the 3rd cylinder was black and the bearings were erased into dust. I repaired it myself, but it still doesn't sound right (but errors don't burn). A friend told me about the problems associated with this model and I found out on the website that there is a review on the engine. Therefore, I immediately went to the Hyundai dealership, where I was refused a recall saying that I had a good engine because the engine error lamps do not burn. To which I objected by saying that the recall policy warns of bringing the engine to jamming and a possible accident (despite the fact that the engine was already on the verge of this). In fact, the motor has already died. What should I do next. I understand if there is a review of a poor - quality engine, it needs to be replaced ( I didn 't come up with it ). Thanks for understanding.

This fuel pump recall 227 was issued on May 2022 and I've yet to be able to make an appointment to get it fixed. The Hyundai of San Bruno I was finally able to reach said they'll call me back when the parts come in. That was almost a year ago and when you call their service department, you can't even leave a voicemail. On some occasions you can leave a voicemail, but it's never returned. This is a fuel pump hose, not a complicated part. They should have this part. This is unacceptable as this recall addresses a potential fire risk.

I already replaced my engine because the car always burned alot of oil. I never had a oil leak but I had to constantly add oil to the car a couple of times a month. After replacing the engine I drove the car for about 4 months. The car started stalling on me (no warning lights) then would start back up after a few tries. This last time I drove the car I was driving my car on a main busy road. I stopped at a red light waiting for it to turn green. The light turned green, I went to proceed and the car just stalled on me again. No warning lights or anything to give me an indication that the car was having issues. I tried to re-start the car and it wouldnt start. I had to get my vehicle towed to a mechanic shop. It has currently been in the shop for about a month now and the mechanic is having a hard time trying to figure out what's wrong with the car. I was told previously that there were recalls on the engine but everytime I call the Hyundai dealerships they tell me there are no recalls for my vehicle. I have already paid atleast $3,500 in repairs and still having issues

I was commuting home from work when suddenly there was smoke coming from under the hood and the vehicle completely stopped working in the middle of the road. It would not accelerate and I had to get help to move it into a parking lot. I had to get it towed to my home. The car will not start. If we turn the key to try to start it, the engine starts smoking.
