On June 3, 2025, I experienced a terrifying and dangerous incident while driving my 2023 Hyundai Tucson Hybrid on a three-lane road at approximately 50 mph. Without any warning, the gas pedal became completely unresponsive, and the car abruptly decelerated from 50 to 20 mph. This sudden loss of acceleration was incredibly frightening, especially with vehicles close behind me that nearly collided with mine. There were no warning lights or check engine alerts. Fortunately, I was able to safely cross all lanes and pull over before having the vehicle towed to a local Hyundai dealership. I shudder to think what might have happened if this had occurred on a highway at higher speeds. This is not the first time I-??ve experienced serious issues with this vehicle. In February 2024, at about 17,000 miles, I received an urgent alert recommending a system check. At that time, the car was revving while idle and would occasionally lurch at low speeds. The dealership had difficulty diagnosing and resolving the issue, and my vehicle remained in the shop for over a month before they ultimately replaced the oxygen sensor. Since then, the car has continued to lurch intermittently -?" for example, when backing out of a parking space or in stop-and-go traffic. In fact, approximately 10 minutes before the June 3 incident, the vehicle lurched several times while moving slowly in traffic. When the car began to lose speed during the most recent incident, I pressed the gas pedal all the way down, but it failed to respond at all. I believe the current issue may be related to the unresolved problems from last year and represents a significant and recurring safety concern. I-??ve also read in Tucson owner forums that other drivers have experienced similar issues, suggesting this may be part of a broader, systemic defect. At this point, I do not feel safe driving this vehicle. I truly believe this car is a lemon. This vehicle is still at the dealership, but they have not given me any updates yet.

2023 Hyundai Tucson with just over 14,000 miles failed to accelerate. After completing a right turn the vehicle seemed like it went into neutral. A green warning light appeared stating limit 20 mph. I now know this is -??limp mode-??. Turning the vehicle off and back on seemed to resolve the issue. The vehicle was towed to the dealer. They found nothing wrong. I was told to take a picture of the warning next time. I was fortunate to not have caused an accident. This is incredibly dangerous.

When pulling out of my driveway onto street, I lost acceleration. My vehicle would not go oer 35 mph and the RPMs were revving up too 5000 without speed moving. I tried changing the drive mode to fix it, that did not help. I pulled over, s topped the car and restarted and all seemed normal. This has happened 2 other times since I bought the car. The other 2 times was while i was on the interstate the engine stopped engaging and i could not accelerate. Both times the issue corrected itself by the time I could get safely out of traffic. This is a major accident concern as there is no warning before this happens.

This Hyundai Tucson was 3 months old when the transmission started to shudder and miss gears. I immediately took it in to Ken Garff Hyundai and the service advisor drove the car and said nothing is wrong with the car and that the transmission needs to break in and sent me on my way. The Tucson did it again while in traffic and the vehicle would not go and I had to put my hazard lights on and let the car struggle in changing gears to get it off the road. The car was towed in to Peoria Larry Miller Hyundai and this was documented by that dealership of the car shuddering and that they thought it was from my insurance plug in device. I explained that the car did it before the plug in. I removed the plug in device and the car continued to shudder. On [XXX] while backing out of my garage the car began to shudder while in reverse and i continued down the road while the transmission refused to change gears. It almost sounded aa if the car was in neutral and the car would on go no more than 3mp. I had the gas pedal floored and the car would not go. I reparked the car back at my home and called Hyundai for a tow. The tow came and the tow driver stated that the seemed as if it is in neutral as he drove it up on to the tow truck. After getting the vehicle to the dealership i was told from the service advisor that this is an ongoing problem with Hyundai's dual clutch transmission and this sounds like the problem.

Engine would not accelerate after stopping at a store. Limped home at 15 mph. Engine light came on a few miles from home. Vehicle would not stay running the next morning and had to be towed to dealership. Problem was an injector that the seal had failed on causing the engine to flood with gasoline. Dealership stated they had seen multiple injector failures and replacement parts now have a different part number implying the injector has been redesigned. Hyundai refused to replace the other injectors as they had not failed yet (they did replace the one that failed). I went ahead and paid to replace the other three. I live in Montana. If I had lost acceleration going up a steep incline or in heavy traffic or car engine failed to stay on in remote area in sub zero temperatures it could have had detrimental consequences.

When driving the car and stopping at red lights, stop signs, or any other stops in traffic on roads and expressways, the car engine randomly dies and cannot restart between 3 and 10 mins. There is no warning when this is about to happen -?" the car engine simply dies and dashboard lights come on. There is no response from the car after shifting in Neutral or Park by pressing the start button with foot on brake. After some amount of time, the car will start. There is no warning before this is going to happen. The dealer (Patrick Hyundai) has inspected the car three times and has not been able to reproduce the problem as this happens randomly. They told me on my third visit to not bring the car back as they don't know what the problem is. The first time this happened was 4 months after I owned the car and has happened in excess of 6 times I now fear for my life when I drive this car. I was almost hit twice. I was stopped on a busy main street at a red light when the light turned green and all cars drove away and the truck approaching me assumed I would drive also but couldn-??t because the car was stalled in the middle of the road. The truck veered away as last second to avoid my stationary car. The 2nd time was on expressway during traffic when stop and go driving was occurring and my car engine died again. As in previous case, vehicle behind me anticipated I would move forward like other cars but couldn-??t and stopped inches from back bumper.

On 6/26/23 I was driving the Tucson. I was stopped at a light in traffic waiting for the light to change. Suddenly the icons on the dashboard turned red and started flashing. A message -??Engine Off-?? displayed and the engine turned off. I was able to turn the vehicle back on and was able to drive. The automatic shut off of the engine while driving presents a safety risk.

I purchased a new vehicle in February 2023. After a month and a half, I traveled to Washington DC on a pleasure trip. After my work/vacation trip when I am returning back to home all of the sudden, there was heavy smoke from the hood and eventually tried to turn off the engine but the car didn't respond, and when I tried to open the Hood in order to cool down the engine I see fire already in the engine. So, there was no intimation on the dashboard about the fire or not even an alert. Moreover, the engine didn't turn off even after trying to turn it off 4- 5 times. I was really worried about what would happen if the door locks stops working

Two days after purchasing this vehicle BRAND NEW, I received a "Low Oil" alert. I took it to the nearest Hyundai dealership where a salesman filled the engine with oil. Only a couple hundred miles later I received another "Low Oil" alert. I have been attempting to solve this issue with Hyundai, however, they are insistent that I must complete an oil consumption test, which takes 3,000 miles of testing to complete. This vehicle is burning oil, and burning oil FAST. I do not know where the burnt oil is going, but if it is going through the exhaust system and catalytic converter this may be a FIRE HAZARD.
