I was contacted by Hyundai last year about a possible recall on my engine so I brought it in October 2023 to have it checked out. I was told that everything with the car was fine. Fast forward to last week 02-21-2024 and my engine starts shutting off while driving ON THE HIGHWAY? I have it towed to a new dealership in Jacksonville FL Jenkins Hyundai I believe. They inform me that it is indeed the engine and it will be replaced for free under warranty. However, it-??s been over a week and the parts for the car are still not available. I have researched online and found I am far from the only one this has happened to. I was not given a loaner car and they did not offer to pay for my rental but I was told they would reimburse me. I was also told that they would just pay every week for a rental car for me but then I was later told that that was a flat out lie. After March 7th when the rental car I have is to be returned I can no longer afford a rental car and will not have access to reliable transportation. This could potentially result in me losing my job. This is unacceptable and Hyundai should be investigated and held accountable for selling cars they know have faulty engines.

The contact called on behalf of his girlfriend who owned a 2021 Hyundai Tucson. The contact stated while driving 5 MPH in the driveway, there was steam coming out from under the hood. There was no warning light illuminated. The contact parked the vehicle. The contact stated that as he opened the hood, flames came out. The contact's girlfriend also saw flames coming out of the A/C vents. The contact closed the hood and assisted his girlfriend and his pet in exiting the vehicle. The contact stated that his girlfriend slipped and fell while exiting the vehicle. The contact's girlfriend sustained back pain and the contact sustained a flash burn. 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 vehicle was totaled by the insurance company and remained in the contats driveway. The dealer was not notified of the failure. The manufacturer was notified of the failure, and a case was opened. 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.

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

Received recall notice that the possibility exist that a battery compartment fire could happen. Recall notice also stated that vehicle should 'not be parked indoors.' The recall notice also stated 'an electrical short in the ABS module could increase the risk of an engine compartment fire.' So we don't dare park the car in our garage since it is located beneath our home, thereby leaving a new car out in the elements at all times. In addition as senior citizens our safety and well being are being jeopardized as we cannot enter our vehicle from inside our home, but must enter from the street in all types of inclement weather. We called the service department but did not receive a call back. We reached out to our salesman and he was the one who gave us information on the recall and added our name to the repair list. However when we didn't hear from them with an update we took a drive to the dealer. During the visit to the dealer in March we were told the piece is on back order. Today I called the service department and was told there is no date yet to fix this recall. How long are we expected to wait for the 'fix' and to leave our car outside?

Severe hesitation when attempting to accelerate from a stop. Car does not move, requires sveral attempts to press the accelerator before the car responds, extremely dangerous when entering an on ramp, merging onto a highway, or in heavy traffic. This has been an ongoing problem with this car, has not been rectified, Hyundai refuses to acknowledge the problem.
