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

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. …
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. …
The vehicle developed an intermittent but potentially dangerous engine control malfunction. After the engine reached normal operating temperature, the engine speed (RPM) would repeatedly surge while the vehicle was stopped in Park and Neutral, fluctuating from approximately 1,000 RPM to over 3,000 RPM without any throttle input from the driver. The condition occurred with the air conditioning turned off and could be reproduced multiple times. At approximately the same time, the Auto Start/Stop system stopped functioning and displayed a warning indicator. A malfunction indicator lamp (check engine light) also appeared during the incident. The warning light later turned off, but the engine surging continued. …
