2023 Hyundai Tucson Hybrid problems

There was/is a recall #290 on the tow hitch harness. There was a concern of a fire risk. Hyundai’s remedy was to cut the harness making the tow hitch unusable. This has been since March. the federal safety agency is not putting any pressure on Hyundai to replace the harness. the federal safety agency doesn’t acknowledge that this recall is still open. All consumers like me who purchased this option can not use it due to the federal safety agency recall. How can I get this issue addressed and resolved. It seams like no one is interested in addressing this problem

I am reporting a critical Exhaust Gas Recirculation (EGR) valve failure on my 2023 Hyundai Tucson Hybrid. The failure resulted in an immediate loss of engine power, reduced vehicle performance, reduced fuel efficiency, and the vehicle entering limp mode while driving, creating a significant safety hazard in traffic. Diagnostic & Technical Details: Error Codes Captured: Diagnostic trouble codes in the P0400 series (EGR system flow/circuit malfunction) were confirmed during diagnostic inspection. Root Cause: The component failure is directly linked to an internal short circuit in the EGR valve assembly, caused by solder flux contamination during manufacturing. Manufacturer Response & Escalation Denial: When contacting Hyundai regarding this failure, I was informed that my vehicle’s VIN is "not included in Safety Recall 260" (the federal safety agency Campaign 24V‑308). I formally escalated this claim to Hyundai Corporate, but my request for reimbursement and coverage was explicitly denied on the grounds that my VIN falls outside the designated recall parameters. However, this exact failure mode, part assembly line, and manufacturing defect (solder flux contamination) are identical to the safety defect described in Recall 260 as well as Hyundai Service Campaign 9B3. Hyundai is restricting coverage based on narrow VIN manufacturing windows despite identical, defective parts being installed across non-recalled vehicles. Because a sudden EGR failure causes unexpected loss of power while traveling in traffic, and because Hyundai Corporate has refused to cover this out-of-pocket repair, I am requesting that the federal safety agency investigate this issue and compel Hyundai to expand the scope of Recall 260 to protect affected owners and mandate reimbursement for out-of-pocket repair costs.

Vehicle exhibits a dangerous 2-to-3-second delay/total loss of accelerator response at low speeds or rolling stops (5–15 mph). When stepping on the gas pedal to pull into traffic or make a turn, the vehicle hesitates completely before engaging power, even when the pedal is fully depressed. This creates an extreme crash risk when entering oncoming traffic or merging.

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. Patterson Hyundai dealer in Tyler, Texas, tried to submit warranty claim and subsequent appeal, but Manufacturer refuses to own manufacture defect. Drivers contacted glass repair companies in the area, and companies explained they had seen this occur several times before. Evidence: Initial Event Photo Indicates Rupture occurred from the inside of the vehicle and not an external force.

1. Sometimes vehicle does not start. Only starts if battery reset button pushed. 2. Sometimes vehicle while moving has delayed braking after juddering. Only stops when car stopped and restarted. 3. Sometimes vehicle while moving suddenly revs, RPMs spike until car stopped and restarted. Engine revs but does not shoot forward. 4. Spookiest of all, while moving car suddenly stops accelerating. Pedal on the floor and it is coasting to a stop. When car stopped, and turned off, then it will work. Had we been on the interstate we would have died, These incidents were sporadic and occurred on and off during the month of April and May. Each of the above occurred numerous times to different drivers. Service at two locations were unable to ID. We sold the moving death trap to one of the Hyundai dealers who could find no mechanical problems with the vehicle. The vehicle was terrifying to drive. There are other reports on this vehicle of these issues ... which appear to be electronic. Hyundai has good engineers. They know what is causing this and simply do not want to replace a very expensive but obviously failing electronic control module.

The windshield had a minuscule chip at the edge and it developed into a big crack. It seems like product defect and maybe dangerous.

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.
