Acceleration issue, from a stop position on a red light or stop sign, when the gas pedal is pressed the engine revs but does not move immediately, after a couple of seconds it lundges forward, also when trying to merge you must wait for a very big gap to safely merge, the car does not respond and this is very dangerous, Hyundai need to rectify this issue before someone dies.

When accelerating, my car seems to hesitate. This happens regularly. The other day, making a left turn in an intersection with on-coming traffic, the engine hesitated to the point that the vehicle stopped moving forward. This was a concern since I did make a timely turn, but hadn't planned on my vehicle almost stopping in the middle of an intersection. My check engine light has not turned on, and the vehicle has less than 30,000 miles on it. I am concerned to the point that I will be taking it to a dealer to check it out.

Which is not possible since the cars Maintenace intervals were maintained. It was also later determined that the oil pan bolt was under tighten due to bad threading on the oil pan and bad oil pan seals. The car will be towed to a dealership for further inspection.

The oil plug fell out of my Tuscon while I driving on the highway and it burned out my entire engine on January 2, 2023, at approximately 5:40 pm EST. The tech at the dealership found the plug in the tray under the spot where the plug goes. It was inspected by a technician at a Hyundai dealership. The car is a 2018 Tuscon--had less than 55,000 miles on it and is now basically worthless and undrivable, quoted $13,000 to fix it. My entire engine now needs to be replaced. I was within the lifespan of my last oil change when the plug fell out. A red oil light flickered on and then a battery subsequently came on. Within approximately three minutes of the light first flickering on, the car was dead on the side of the highway. The car would not turn over once it was stopped on the side of the highway. The car is still at the dealership and available for inspection as of today, but I am not sure how long it will be there because I am not sure what is the best path forward in terms of repair because of the financial cost. I'm lucky that I was able to navigate my car onto the shoulder of the highway and secure a tow without injury. It was a very foggy day and it was already dark when this occurred and I was afraid I would be struck if I exited my car. My car drifted to a stop at the start of an exit ramp with a highway barrier that prevented me from going farther right onto the shoulder.

Vehicle stalls when accelerating at low speeds. It appears to be a delay when the car transitions from 1st to 2nd gear. This creates a safety concern, especially when taking turns into traffic due to delays/stalls when turning.

The oil fuel tank has been burning oil too fast in the GDI Engine & the oil has burnt through my alternator and spark plugs that I recently fixed only three weeks ago. This caused the engine to lock up completely while I was driving several times & I lost control while driving - having to restart the car multiple times to move it to a safe area. Now, the engine has locked permanently and I am unable to start the car at all despite replacing several parts and getting an oil change every 3-5000 miles (which continues to leak too quickly and harm other parts in the car).

Got to closest gas station and had car towed back to dealership, I just want to point out that the knock sensor is going to put people in danger in certain situations like myself, I am not to happy.

The engine caught on fire, it was considered totaled loss. I settled with the insurance and not sure if the car is still available for inspection. My safety was put at risk because I was driving the car when it happened. I did not get injured because I was able to get out of the car. There was no recall from what I know. The car was inspected by GEICO which is why it was considered totaled loss. There was no warning before the fire. The car was in great condition.
