FUEL/PROPULSION SYSTEM — Filed 07/05/2026

2023 Hyundai Tucson Limited, 2.5L GDI, Alabama-built (VIN 5NMXXXXXXXXXXXXXX), built [XXX]. On [XXX], at about 37,550 miles, the check engine light came on flashing and the engine ran rough while I was traveling in Canada. My scan tool showed P0300, P0302 and P0304 (misfires on cylinders 2 and 4). On July 6, 2026, Experience Hyundai in Charlottetown, PE (service order 92XXX) replaced one ignition coil under warranty. No fuel injector leak test was performed. The misfires returned. On [XXX], at 39,409 miles, my scan showed P0302 active and P0304 pending. The car also had extended cranking after sitting and the check engine light was on. I was told I could keep driving the car unless it started to jerk or engine light started to flash, then immediately stop driving it and have it towed. On September 25, 2026, the car was towed to McGovern Hyundai Route 2, Leominster, MA (invoice 148XXX). The dealer found all 4 fuel injectors leaking and replaced them under warranty with injector service kit 35399-2S133QQH. My vehicle is outside the production range of Hyundai TSBs 23-FL-002H-1 and 26-FL-001H, which cover this injector failure only for Alabama-built Tucsons produced through July 11, 2022. Yet it failed in the same way. I am concerned the defect extends beyond the bulletin dates and that a sudden misfire could cause loss of power in traffic. There is no recall for this condition. The dealer found all 4 fuel injectors leaking, even though only cylinders 2 and 4 had set misfire codes and replaced them under warranty with injector service kit 35399-2S133QQH.

The car was working perfectly fine I drive it for work all the time and one day it started shaking weirdly. A couple days later the check engine light turned on. It was throwing the code that was pointing to "misfiring in the 3rd cylinder" We changed all the spark plugs, 3rd cylinder coil pack, and switch the coil pack to see if it would say a misfiring in a different cylinder. We then took it to a mechanic saying that it is the high pressure fuel injectors and that he has seen this problem with other Hyundai Tucson around the same year as us and that there was a bulletin on it.

SUSPENSION — Filed 07/20/2026

The right rear shock absorber failed and was replaced under warranty at approximately 22,000 miles. The car was making noise, the shock was leaking, and not working properly. The dealer admitted to problems with rear shock absorbers failing at low mileage on Hyundai Tucson Hybrid SUVs 2022 through 2025 Tucson Hybrids. The left and right rear shock absorbers are the same part number so we now expect the left side to fail but the dealer will not replace the left until it fails.

FORWARD COLLISION AVOIDANCE — Filed 08/06/2026

While backing out of driveway, with parked vehicle along side and one moving vehicle in the road, I was applying the break and the Emergency Stop feature activated. My speed was 2-3 MPH and slowing.

FORWARD COLLISION AVOIDANCE — Filed 08/06/2026

Emergency Brake applied while driving. Had been driving with vehicle in front, on each side and one at rear with issues and all of sudden the emergency brake was applied causing the vehicle in back to get very close to my car. This is has happened multiple times and reported to dealership multiple times. This was the second occurence on this day.

ELECTRICAL SYSTEM — Filed 07/18/2026

Under Hyundai Recall 290, the dealership permanently removed the functional trailer light wiring harness and replaced it with a nonfunctional rubber dust cap. A Hyundai case manager informed me that a replacement harness is "in development," but official NHTSA remedy filings show the cap is the final remedy, resulting in the permanent loss of a factory feature I paid for. The removal of towing functionality without a clear timeline for a safe replacement parts remedy constitutes a failure to properly correct the vehicle defect.

AIR BAGS,UNKNOWN OR OTHER — Filed 04/01/2025

My client lost her right eye and suffered a brain injury when an aftermarket rhinestone emblem decal from her steering wheel shot into her face during a low-impact crash with a deer. The crash left minimal damage to the front end of the vehicle, but caused the airbags to deploy, shooting the decal into my client’s head. She purchased this dangerous decoration on Amazon, and despite NHTSA notices in 2023 and 2024 telling consumers to “avoid purchasing these steering wheel decals for all vehicle makes and models” and to “remove any such decals that they have already applied to their steering wheels,” this warning was not passed on to my client, even though records are kept of individual customer purchases, and these warnings could have been easily shared. A recent check of Amazon’s Safety Recalls and Alerts webpage did not turn up the 2024 NHTSA notice. I am sure there are other Amazon customers out there, who, like my client, have no idea just how dangerous these things are.

ELECTRICAL SYSTEM,UNKNOWN OR OTHER,ENGINE — Filed 07/13/2026

The vehicle developed an intermittent but potentially dangerous engine control malfunction. After the engine reached normal operating temperature, the engine speed (RPM) would repeatedly surge while the vehicle was stopped in Park and Neutral, fluctuating from approximately 1,000 RPM to over 3,000 RPM without any throttle input from the driver. The condition occurred with the air conditioning turned off and could be reproduced multiple times. At approximately the same time, the Auto Start/Stop system stopped functioning and displayed a warning indicator. A malfunction indicator lamp (check engine light) also appeared during the incident. The warning light later turned off, but the engine surging continued. This unexpected increase in engine speed raises concerns about unintended vehicle movement or loss of driver control if the condition were to occur while shifting into gear or while driving. The unpredictable nature of the malfunction presents a potential safety risk to the occupants of the vehicle and to others on the road. The vehicle has been taken to an authorized Hyundai dealership for diagnosis and repair and remains under inspection. The problem is available for inspection. During my research, I found numerous reports from other Hyundai owners describing similar engine surging, idle fluctuation, and Auto Start/Stop malfunctions involving comparable vehicles. Because similar complaints appear to have been reported by multiple owners, I am submitting this report so the issue can be evaluated for a possible broader safety defect. I have videos of the incident

FORWARD COLLISION AVOIDANCE — Filed 05/30/2026

2023 Hyundai Tuscon XRT has a dangerous and alarming issue. The Emergency Braking engages at highway speeds where no risk is present. The car groans and pulls dangerously. In addition, the Forward Collision Warning engages on surface streets every 10-15 seconds and there are no risks present. The emergency braking issue has occurred on several occasions. The Forward Collision Warning issue occurs every time the car is driven.

UNKNOWN OR OTHER,FORWARD COLLISION AVOIDANCE — Filed 01/14/2026

At dusk I was driving below the speed limit (40 MPH). I was at least 3 car lengths behind the vehicle in front of me when i saw the driver was braking because his brake lights came on and there was an intersection ahead with a stop light. There were at least two cars ahead of the vehicler I was behind. I braked but the car kept on going and appeared to accelerate. I was unable to stop the car with the brakes and collided with the car ahead. It was a sturdy vehicle with a strong bumper so I did not do much damage, if any, to the vehicle but my car requires 6,645.90 of repairs. No one was hurt and the air bags did not deploy. I was wearing my seat belt. There was no warning from ny vehicle that I was getting too close to the vehicle ahead and my car made no attempt to brake automatically. It was as though all warning indicators were not functioning. I have had two other incidents of the car surging ahead but did not report it because no one else was involved and I was able to correct the speed and I thought it was just my imagination.

POWER TRAIN,AIR BAGS,VEHICLE SPEED CONTROL — Filed 12/04/2025

As I was pulling into a parking space in a parking garage, the vehicle's engine revved, tires squealed and then the vehicle propelled forward on its own, without my foot being on the accelerator. The vehicle only stopped when it hit a support column and the wall of the parking structure. There was extensive damage to my vehicle and to the parking structure wall. My safety and the safety of others was put at risk due to the car accelerating on its own. The problem has not been confirmed or reproduced by the dealer, but we did take the vehicle to the dealer for inspection and they said they could not find anything wrong with the vehicle that would have caused the unintended acceleration. The vehicle has been inspected by the manufacturer, the insurance company and an investigator for Hyundai. Hyundai infomed us that they are not taking any responsibility for anything that occurred and that they will not share their investigator's report with us. There were no warming lamps or messages related to the problem prior to the failure. However, there have been other occasions while driving on the open road when the engine has revved on its own and I told Hyundai about that. In doing our own research, we have found that there are other 2023 Hyundai Tucson drivers who have had this exact same problem (unintended acceleration causing a crash) while pulling into parking spaces. Additionally, the air bags did not deploy during the collision and therefore the incident was not recorded by the EDR.

LANE DEPARTURE,BACK OVER PREVENTION,FORWARD COLLISION AVOIDANCE — Filed 10/15/2025

I was backing out of my driveway, which is on a busy street. I waited for the traffic to clear. I backed out onto the main road, which I thought was completely clear, but a car came behind me and I smacked right into him. There was no beeping from my car, and the automatic braking system did not engage at all. The rear of my car, particularly the driver's side, was severely damaged. The other car's passenger front door was badly damaged. The side curtain airbag on their car deployed and their vehicle (Volvo station wagon) was not driveable. The emergency braking system frequently engages unexpectedly when I back out of my driveway, even when there is no hazard. The unexpected braking is oftentimes dangerous. However, this time, when I needed it, it did not engage. An outside diagnostic inspection was done on the vehicle, and showed "no event." If you saw the cars involved in the accident, it is clear there was a significant "event."

As I was parking my car in a parking spot going about 5 miles or less. My car surged forward at a very accelerated speed, and I ended up running into a brushed and a metal fence, which is what stopped me. There were no warnings that went off on my car. No emergency brakes, nothing.

STEERING — Filed 06/29/2025

On [XXX], while driving a 2023 Hyundai TUCSON SEL, the steering wheel suddenly and completely detached from the steering column and ended up in the driver's lap. This sudden and absolute loss of steering control is a catastrophic failure of a primary safety system that placed the driver's life and potentially the lives of others in immediate and extreme peril. It was only due to sheer luck that the vehicle was brought to a stop without an accident or injury. Following the incident, due to fear and anxiety, the driver is now in treatment and has been unable to work. The vehicle was transported to Ron Marhofer Hyundai on the same day. The following day, the driver was met with a profound lack of respect and professionalism from the service advisor, Declan McCready. The driver and her mother were implicitly told they did not know what they were talking about and were treated with a profound lack of respect. The service advisor initially asserted there was no warranty coverage for the issue and that it would cost nearly $500.00 to fix. He also claimed his entire shop of mechanics looked at the car and found nothing was broken. However, the very next day, the dealership abruptly reversed their diagnosis and instructed the driver to get a rental car, stating they would now be fixing the vehicle under warranty. The repair order confirms the technician's findings: "verified concern steering column separated stopped bracket bent and separated replaced column housing operating normal". The vehicle had 14,479 miles at the time of the failure. There were no prior warnings or symptoms before the incident.

VEHICLE SPEED CONTROL,SERVICE BRAKES,FORWARD COLLISION AVOIDANCE — Filed 06/20/2025

For the second time in a year, I was pulling into a parking space and when I applied the brake, the car accelerated, seemed to be airborne and lurched forward. Though I firmly had my foot on the break, it would not stop until it hit a brick post about three feet away. This exact same scenario happened in July of last year. Then, I hit a stand of shrubs. Someone said, your foot must have slipped off the break and hit the accelerator. I said, “I don’t think so.” Yet, I took the blame for the accident, for I could not believe it was a car malfunction, nothing close to this had happened to me since I owned the car. Everything was the same in the last crash as in the first. This time, as soon as the car accelerated, I checked, and my foot was firmly on the break. There is definitely a malfunction in the car. The black.box Should be recovered and read by someone not associated with Hyundai. I checked on Hyundai Tucson Owners’ group on Facebook, and my incident has been reported by others.

AIR BAGS — Filed 11/24/2024

I was driving straight when a vehicle coming from the opposite direction made a left turn without yielding, crossing into my lane. As a result, my vehicle collided with the other car at full speed. However, the airbag in my steering wheel did not deploy upon impact, as it should have. My injuries have been significantly more severe than they would have been had the airbag functioned properly. I reported this issue to the vehicle manufacturer, and they opened a case and conducted an inspection. During their inspection, they found that the airbag had since deployed. However, my vehicle was transported off a steep hill and moved to multiple lots before the inspection, any of which could have triggered a delayed deployment. Despite this, the manufacturer has refused to accept liability. Because the airbag failed to deploy at the time of impact, there was no buffer between me and the steering wheel. This resulted in excessive force against my chest from the seatbelt and direct impact with the steering wheel, leading to more severe injuries. There were no warning lights on in the vehicle before the crash, nor were there any recalls related to this issue at the time of the incident.

I purchased a new vehicle in February 2023. After a month and a half, I traveled to Washington DC on a pleasure trip. After my work/vacation trip when I am returning back to home all of the sudden, there was heavy smoke from the hood and eventually tried to turn off the engine but the car didn't respond, and when I tried to open the Hood in order to cool down the engine I see fire already in the engine. So, there was no intimation on the dashboard about the fire or not even an alert. Moreover, the engine didn't turn off even after trying to turn it off 4- 5 times. I was really worried about what would happen if the door locks stops working
