What 1,076 owners told NHTSA about the 2017 Hyundai Tucson Hybrid Hev

The panoramic sunroof glass suddenly shattered while the vehicle was being driven on the interstate, with no visible impact, object strike, or prior damage observed. The component involved is the sunroof glass panel, and it has already been removed and replaced through insurance repairs, so it is not available for inspection (however, pictures are available upon request). The incident created a loud, explosion-like sound and resulted in glass fragments falling into the interior of the vehicle, including onto the driver and the front-seat passenger, causing minor injuries. This also created a significant safety risk due to driver distraction, panic, and the potential for more serious injury while the vehicle was in motion at highway speeds. The issue has not been reproduced or independently duplicated by a dealer or service center; however, it was inspected and documented by the insurance company and repair facility during the claims and repair process, which confirmed that full glass replacement was necessary. The vehicle or component has been inspected by insurance representatives and a repair shop, but it has not been inspected by the manufacturer or law enforcement. There were no warning lamps, dashboard messages, or any prior symptoms indicating a problem before the failure occurred, and the sunroof appeared to fail suddenly and without any advance indication while the vehicle was in motion.

On [July 4, 2025], while driving, my vehicle experienced a sudden loss of power followed by smoke and flames coming from the engine compartment. The fire required emergency response and caused significant damage to the vehicle. Thankfully, no one was injured, but the incident posed a serious risk to my safety and others on the road. I had not received any prior warning signs such as engine knocking or warning lights. The fire appears to be directly related to the known defect outlined in Recall 209. I am requesting that NHTSA investigate this incident and ensure Hyundai is held accountable for the full scope of this defect, including fire risk. I am also seeking assistance in ensuring Hyundai provides appropriate compensation or resolution for the damages caused.

My concern is who is going to pay for the damage to my car? I initiated a claim with Hyundai due to my car malfunctioning at a stoplight, the light turned green and I gently pressed the accelerator and it lurched forward and smashed into the car in front of me. I had taken my car in multiple times telling them the accelerator sticks and hesitates. Each time they told me nothing was wrong with it. I researched online and I found many people were having this same issue with the accelerator in the 2017 Hyundai Tucson. I was also told there is a software update available to help with this. The service department at the Dealership said there is not one. I have an appointment with the Hyundai service department on 12/20, I need to know who is going to pay for my car.

My vehicle was broken into on Nov. 17, 2022 and thieves attempted to take the vehicle after smashing the back passenger window and gaining access. The vehicle alarmed once they either attempted to either open the drivers side door or start the vehicle. Police were called and completed a report on scene. On Nov. 23, a thief returned and gained access to the vehicle by shattering the glass on the back driver side of the vehicle before getting inside and driving off in the vehicle. I reported the vehicle stolen to police and the vehicle was recovered later that evening. On Nov. 25 I went to the tow yard where the car was taken to retrieve my belongings and observe and record the damage. The entire steering column was stripped down and damaged which is how the thief was able to start it. There are highly circulated videos on social media platforms showing criminals or would be criminals how to do this. It is now also known that they are targeting specifically Kias and Hyundais due to Hyundai manufacturing cars between 2016-2020 without immobilizers. My make and model being one of them and therefore making me a target. Not only that but the cars are being taken and used for joy rides, as mine was, or used in crimes. My car sustained additional damage as it was crashed into another vehicle during the thieves joyride before they ultimately jumped out of the car and abandoned it in an intersection. I was targeted, my livelihood put in jeopardy and if the car is fixable I will still be in harm's way once the repairs are completed. Hyundai needs to be held accountable as there is no way I would have purchased this vehicle knowing that the car was missing a major safety and anti-theft component. Further, why were they allowed to manufacture and sell these cars without such an important component??

I have had an ongoing issue with my 2017 Hyundai Tucson since May 17, 2021. Like many other owners, I have recently learned about the recall on engines for the 2017 Hyundai Tucson. In the information with the announcement of the recall, the article stated, “The issue has caused at least 18 fires, but no injuries, according to documents from the U.S. National Highway Traffic Safety Administration”. I wanted to know if my vehicle was one of these 18 fires? If it was, I would like to know that I will be covered under this recall, and the engine in my vehicle will be replaced. I can begin to be reimbursed for the $1,000s of car rentals that I was told would be reimbursed before my warranty claim was denied. If it is not one of those 18 cars? Why not? I will give more information below on what happened to me and my car. Through further research, Attachment A on the NHTSA website states that “As of the date of this filing, Hyundai is aware of 45 fires related to the recall condition”. Once again, I ask if my vehicle is on this list? If not- why was it not after the engine fire and the below happenings occurred to me in May 2021. Happenings On May 17, 2021, I was driving home from work on Interstate 195 in New Jersey. My check engine light came on the previous week, and I immediately brought my car into an auto body to receive an oil change and a 25 point maintenance inspection. But, unfortunately, the check engine light went off. While traveling on the freeway at approximately 65 - 70 miles per hour, I could feel my acceleration beginning to get slower and slower and harder to use. I was pressing entirely on the accelerator, and the car continued to go slower Suddenly, the acceleration stopped completely, and all the lights on the dashboard went on. I noticed smoke started to appear from under the hood and from the tail of the vehicle. After nearly being hit by another car, I was barely able to get into the shoulder. I just so happened to break down on the part of
