There was no further information provided. The contact stated that the entire vehicle caught on fire. The contact was able to extinguish the fire with the assistance of the fire department. A fire department report was filed. No police report was filed. The insurance company technician determined that the fire originated from the engine compartment.

The failure mileage was approximately 25,000.

I was merging onto interstate traffic when the vehicle suddenly stuttered and decelerated. I managed to merge, then cross over several lanes of traffic and pulled over. Thought maybe a fuel problem (I had just filled the tank), or overheating. It only has 24K miles on it, and I've faithfully taken the vehicle to the dealer for regular service intervals, so I know it is not a fluid leak or problem. after a few minutes, I was able to start the car again, but it immediately shut down. Did this several times before giving up and calling for a tow truck. Had it towed to the dealer, and the next day they told me it needed a new engine, but the service department needed approval from corporate Hyundai. I'm waiting with baited breath.

I've had numerous issues with my vehicle, including power steering, brakes, loss of power, and more. On a few occasions, I started my vehicle and put it into drive, only to find that the power steering hadn't disengaged. This led to near collisions, such as almost hitting another vehicle while backing out of a parking spot and nearly running into a wall. I've reported these issues to Hyundai multiple times, but the dealership can't reproduce the problem, despite having recordings of the incidents. I've also experienced delayed release of the electronic e-brake and it feeling like it hadn't fully disengaged. In a recent event, with passengers in the car, the e-brake auto-engaged while driving downhill, bringing the vehicle to a halt. I had to manually disengage it and restart the vehicle to resume normal operation. I contacted Hyundai customer service again, but I'm still waiting for a formal response. Other symptoms include loss of power during acceleration, engine starting issues, stuttering, and occasional burning smell from the brakes. Despite my efforts, Hyundai hasn't provided any solutions to these problems. I drive with multiple passengers in my vehicle all the time, including children and have major concerns regarding any of these issues happening, let alone while I am driving at higher speeds or with someone else driving my vehicle.

March of 2021 I purchased a new Hyundai Tucson SEL. I have performed all required maintenance (at the dealer no less). In May of 2022 the dealer performed the recall Campaign 966. Since that time, my Tucson has had to go to the dealer 5 times for a P1326 code. This resulted in the check engine light flashing and the car going into protection or limp mode. The vehicle would not accelerate past 30 mph and would not exceed 2000 RPM. This has happened as I have accelerated from either a stop or while in traffic. As of yet the dealer has been unable to permanently resolve the problem. They have replaced the knock sensor. The dealer has replaced spark plugs. The dealer has also replaced the catalytic convertor. They also recently scoped the cylinders and cleaned the engine with pressurized engine detergent. In the days and weeks prior to the check engine light, I can always tell that failure is imminent. The gas mileage will slowly drop off during both highway and city driving. Additionally, I can feel through the gas pedal hesitations and slight rhythmic pulsing. Lastly, I can feel gradual power loss in acceleration and very slight hesitations in acceleration as well.

Check engine light comes on flashing for a knock sensor. This has happened four times. Since it is flashing, car goes into limp mode and won’t go over 2000 rpm, low speeds and slow/no acceleration. It is dangerous due to happening on highways and going from cruising speeds to a crawl, with minimal ability to accelerate, very quickly. Sensor has been updated once and sensor has been replaced twice. Currently dealing with corporate after the fourth time of this issue happening. I am still fighting this issue and it’s looking like I will need an attorney.

Recall Code 966 22-01-028H-1 Think and investigation is needed on these recalls. Apparently the engine can catch fire while the motorist is driving. I'm scheduled to drop my car off on the 9th and was told they may need to keep for 3-5 days. Thes vehicles should not be on the road at all and rental cars should be provided free of charge until the manufacturer works out all the problems

The contact then drove the vehicle to the dealer however, the mechanic was unable to determine the cause of the failure. The contact stated that he was notified of a possible transmission failure. The manufacturer was not notified of the failure. The failure mileage was 9,000.

Purchase new Tucson from Hyundai of Saint Augustine FL in April 2021, the vehicle worked fine. Then in July 2021 the vacuum assist brakes would not hold a vacuum after the engine was shut down, so when you went to start the vehicle it required excessive pressure on the brake peddle to clear the interlock before the vehicle would start. Took vehicle to dealer and told service writer that I thought it was the Check Valve leaking. After 2 hours service writer told me Tucson was ready and their technician did not find anything wrong and that there is no Check Valve. Drove vehicle home and the vacuum assist brake was still not correct so I filed a case with Hyundai USA (#18769467) about the problem and waited for them to contact me. When they contacted me they told me to take it back to dealer and they would fix the problem. I know enough about vehicles that use engine vacuum for power assist brakes have a check valve, so before I went back to dealer I looked up the part number (59139-2W000) vacuum intensifier, and the Hyundai patent (US7752841B2) which clearly shows a check valve. Went back to dealer in October as instructed by Hyundai and told the service writer the same thing I told him the first time. Waited 2 hours again and was told the technician did not find anything wrong and there is no check valve. I then showed him the part number and said that is the check valve. He said he would check with the service manager to see if Hyundai would cover the cost to replace the part and would call me later. Got the call and was informed that Hyundai would NOT pay to replace the part because the dealership technician did not find any thing wrong. How could the technician find anything wrong with a check valve when he said there is no check valve in the brake system. If the engine quit while I was driving I would not have power assist brakes which could cause an accident. I bought the part from different dealer & installed it, brakes work fine now.

Vehicle becomes unresponsive to the gas pedal after idling at a red light, acceleration is delayed for about 5 seconds. After the cars check engine light turns on and the vehicle begins to idle rough. Vehicle shakes randomly when coasting above 30mph and does not want to accelerate when pressing the gas pedal.

It appears after breaking, the brakes stick and the car won’t accelerate when pressed on the gas pedal.
