While driving, I am repeatedly receiving a sudden “trunk open” warning on the dashboard. This warning is often accompanied by a loud noise, which can be startling and distracting while the vehicle is in motion. The abruptness and unexpected nature of the alert are alarming, especially on highways or in high-traffic situations, where any distraction could pose a serious safety hazard. This issue has occurred multiple times, and I am concerned that it could potentially cause an accident, either by drawing my attention away from the road or by causing confusion to other drivers who may see the trunk appearing to open or triggering the warning lights. The recurrence of this problem suggests that it may be due to a malfunction in the trunk sensor, latch system, or electronic control unit. This is not only inconvenient but potentially dangerous for the person operating the vehicle. I urge that this be investigated thoroughly as it may affect more vehicles and pose a broader safety risk if not addressed.

VIN: [XXX] Component Failed: Panoramic Sunroof Type of Failure: Spontaneous Explosion/Rupture from the Inside Occurred: Saturday [XXX] at [XXX] Road Conditions: Smooth Road, Clear Day (No Rain or Hail), Temperature mid 80’s degrees Fahrenheit, No Other Cars on Road. Milage on Car: 19640 Initial Event: Driving on the road when passengers hear what sounded like a gunshot (no firearms present in the vehicle). Pulled over to the side of the road to check tires. Tires were okay but noticed the sunroof had spontaneously shattered. Initial Event Photo Indicates Rupture occurred from the inside of the vehicle and not an external force, but there was no access from the inside of the vehicle as the additional fabric roof prevented shrapnel from entering the vehicle. The glass continued to crumble as the driver returned the vehicle to the house for safety concerns.

Horn does not work. On going issue with this model per Hyundai Tucson forum.

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.

The contact owns a 2023 Hyundai Tucson. The contact stated that while driving approximately 60 MPH, there was a loud explosion coming from the roof of the vehicle. The contact pulled over to the side of the road and discovered that the rear of the sunroof had exploded, and there was glass inside the cabin of the vehicle. The vehicle was taken to the dealer but was not diagnosed or repaired. The Insurance Company was contacted and referred the contact to Paul Island Glass and the sunroof was covered with tape. The glass was scheduled to be replaced, but the vehicle was not yet repaired. The manufacturer was informed of the failure. The failure mileage was approximately 20,000.
