ENGINE, FUEL/PROPULSION SYSTEM, POWER TRAIN
The vehicle is slow to accelerate and as its accelerating it often will jerk or hesitate roughly. There have also been times when accelerating, such as getting on a highway, that the whole (what I assume to be) throttle system will almost stop and it feels like the car is just going to stop right there on the highway. It's very dangerous as cars behind me are also accelerating and not expecting my vehicle to just stop. The vehicle is available for inspection. There are no warning lights, messages, or symptoms prior to the issue. It has not been inspected by anyone yet.

FUEL SYSTEM, GASOLINE:DELIVERY:FUEL PUMP
The top of the low pressure fuel pump in the fuel tank was cracked. A strong fuel smell was present near the rear of the vehicle. When the vehicle was placed on jack stands, leaking fuel was visible on the sides of the fuel tank. The rear seat was removed, fuel pump access cover was removed, ignition was turned on and fuel was observed leaking from cracks on the top of the low pressure fuel pump. This is a huge safety concern due to fuel leaking from the fuel tank. I know for a fact this is not an isolated incident, you can watch YouTube videos of others with the exact same problem. The dealers want $1K+ to repair. I was an ASE Certified mechanic for 20+ years experience, I purchased an OEM fuel pump through an online retailer for ~$600 and replaced it myself. Problem solved, but for how long? There were no warning lamps or messages, the only sign was the strong smell of fuel.

ELECTRICAL SYSTEM, FORWARD COLLISION AVOIDANCE: WARNINGS, ENGINE
I first begin having an issue with the idle speed. It would jump up to 1,500 RPM, which is twice the normal 750 RPM level It started almost from the very beginning when I purchased this car new in early 2020. I mentioned it at first oil change at dealer at 3,500 miles. I was told it was normal. In the beginning it would come and go. Sometimes not happening for weeks in-between episodes. Then it started to have the check engine light come on after it would happen and stay on. I took it back while light was still on and they kept the car for several days. Said it was the EPV valve and replaced it. Car operated fine for a few days then started up again. It also started to idle up and down from 1500 down to 500 in a rapid succession. I was able to get it to stop sometimes by turning engine off and them back on. Again I contacted dealership and took car back in. They gave me a loaner car and kept my car for over a month. This time they replaced the computer they told me. I did not have car for more than a week before it started doing it again. It has gradually gotten worse and happens more often now. It has also started to have the Forward Collision Avoidance warning come on in addition to check engine light as well. Just this week it actually just died on me while driving and forced me to pull to side of road. Turn off the engine and restart the engine. This happen 3 times in succession. Dealership does not seem to have any idea on what is going on and have been not very helpful. 3 week wait to get an appointment to bring in and no loaner cars available. This problem with the 2020 vehicle is very dangerous. It can idle up at anytime and car will lurch, requiring forceful brakeing . Car dying while driving and losing power as well.

ENGINE, FUEL/PROPULSION SYSTEM, UNKNOWN OR OTHER
Vehicle suddenly lost power while in operation. Vehicle was in motion approaching an intersection. When left turn indicator was activated, all lights on the instrument panel illuminated, the engine shut off, and power steering was lost all while the Vehicle was in motion approaching a intersection with stop sign. Vehicle was able to stop before entering the intersection, but would not start again and we were stranded in the middle of the road. Electrical systems appeared to be working. Battery and alternator are functioning normally. After Vehicle sat for 20min, it then was able to start and moved out of the road to a safe location. Vehicle was towed to mechanic that confirmed Battery health and alternator functioning. Vehicle was then taken to dealership for recall 210 safety repair. Dealership service unable to determine cause for loss of power while Vehicle in operation. No explanation, offer of additional service, or remedy has been offered despite requests. I do not feel it is safe to operate this vehicle in the absence of information related to the sudden loss of power during normal operation. Had this occurred in another setting with more traffic or less room for safely coasting to a stop, serious injury or worse could have resulted. The vehicle is still eligible for the 10yr 100k mile powertrain warranty and I am the original owner. We do not feel we can safely operate this vehicle and need guidance on how to proceed with pursuing a remedy to the situation from the vehicle manufacturer.

ENGINE, POWER TRAIN, FUEL/PROPULSION SYSTEM
It's knock sensor issue code was showing since 85000 mileage, dealer just got rid of the code and said can drive safely. Then again at 101000 mileage knock sensor code and Hyundai dealer said software is updated can drive safely. Also it's engine oil burning faster that we keep on topup oil all time. Then at after 108000 mileage my car started overheating, & it's engine seized. Now Hyundai don't want to fix such problems. I don't know maybe it get fixed, then catches fire on highway can cause death.

ELECTRICAL SYSTEM, STEERING, UNKNOWN OR OTHER
The power steering system appears to be failing. There is no indication of the failure prior to failing. When making turns the power steering would randomly stop working, all emergency lights would turn on, and the steering would become extremely difficult to control. This becomes an extreme safety issue when I’m driving around other vehicles. I took my vehicle to a mechanic and they explained that the power steering is electronic, therefore power steering fluid will not fix the problem. Also, there’s an electrical issue with the windows as well. The passenger window can no longer can be controlled by the driver. Lastly, the AC has failed as well. It blows out only hot air. I’ve taken my car to the manufacture dealership and they assessed my vehicle for the AC problem, but they stated that it’s working fine. This is not true because I’ve continued to have problems with the AC, even after many failed troubleshooting attempts. To summarize my report, I have a total of 3 issues in order of importance, power steering, power windows/electrical, and air conditioning unit. My car is available immediately for inspection upon request. Thank you.

FUEL/PROPULSION SYSTEM, ELECTRICAL SYSTEM, ENGINE
While driving the car flashed "Hybrid System Warning! Safely stop and do not drive" and immediately shut off propulsion. I was able to coast just enough to get off to the side of the road. Now the warning comes up as soon as the engine kicks on to charge the hybrid system and the car will not move. If I wasn't in the right hand lane on the highway this could've caused an accident. This happened once in December 2021 with about 86000 miles and went away after letting the car sit for about 30 minutes. It happened again today July 21, 2022 and left me stranded. The car is unusable as of now.

ELECTRICAL SYSTEM, ENGINE, POWER TRAIN
My ABS lights came on and then minutes later my check engine light kept blinking while my car kept stalling or not let me accelerate in the middle of traffic. It’s like the engine dies but the car is on. It only stalls for a second then accelerates then stalls again and accelerates. Almost caused an accident. Seems that this is a problem for a lot of these models. It’s just crazy how it all happened back to back. My car has been running fine otherwise till that happened.

ENGINE
When arriving at a stop and then making a turn on a street vehicle came to a halt. It would not turn on again. The vehicle was able to be pushed to the side, and started to have a knocking sound from the engine, after vehicle was started . Searching thru the internet found recall campaign 312, that has same issues I experienced. Vehicle is drivable but has loud knocking sound as the speed goes up. Also, vehicle was purchased with a rebuilt title and is road worthiness.
