   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.

   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.

5. Filed Aug 7, 2026Failure Jul 18, 2026Chicago, ILElectrical system

   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.

   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.

   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.

    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

    I was on the highway on the way to work when my car started stalling. Every time I pressed the gas to give it some power, it would not go anyway where. after getting it towed to get looked at some of the fuel injectors failed and were misfiring. The warning message about ‘check engine’ popped up 2 minutes before it happened. this is the third time now in less than 6 months.

    I received a letter in March that there is a problem with The Tow Hitch Harness Accessory which could lead to a fire etc. They said they will come out with a repair. I contacted the Victory Hyundai dealership in Jefferson Ohio where I got the car in April and they said they have a repair but the trailer electrical/ lights will not work. I got a second letter saying they have a solution for repair in May I contacted Classic Hyundai twice to make sure the repair now will allow the lights and brakes on the trailer work. Julie and Jesica there said all would be fixed and the lights and break lights will work. I brought the car there June 5th 2026 and asked again if all would work. Lyna there said no. I left. I called U-hall Streetsboro Ohio and talked to Bill who handles the hitch repairs and they said they could fix totally and have for some dealerships. I called Hyundai customer service Kyre and asked if Hyundai in Streetsboro Ohio can be set up to have it repaired. He said no. He would not document his response to me. I bought this car with their factory installed hitch because I needed one to pull my boat and move other stuff. My lawn tractor broke down and I have to pay $135 to have it towed for repair. I am unable to fish in my boat since I can not pull it. There is a repair that will work at U-haul and they are ignoring it.They want to make the hitch unusable. Uhaul will fix for $250-$350. If they disconnect the hitch electrical and the car is sold the new owner can get into an accident since they would have no lights and break lights, turn signal. This is a high risk for an accident. They intend to eliminate the fire risk and create an accident risk for the trailer now not working. What kind of engineers they have?? They should be contacted about this situation. It has been several months with no solution when one exists. I have had multiple Hyundais and will no longer purchase another vehicle from them. You should communicate with them on this issue.

    While driving on a highway shortly after taking delivery of this vehicle as a Certified Pre-Owned purchase from an authorized Hyundai dealership, I experienced sudden and total brake failure. The Electronic Parking Brake (EPB) warning light illuminated and an audible warning chime sounded. The brake pedal did not respond normally. I was unable to slow the vehicle with the brakes and was forced to make an emergency maneuver to exit the highway and come to a safe stop. Upon inspecting the vehicle after stopping, I discovered that the rear left brake caliper had completely detached from its mounting bracket. The caliper was on the ground beneath the rear of the vehicle. Brake fluid had leaked onto the road surface. The vehicle had been in my possession for less than one full drive since purchase. As part of the CPO certification, the selling dealer performed a multi-point inspection and documented installation of new brake pads and certified the brake system as in good working order. The detachment of the caliper is consistent with mounting bolts that were either not reinstalled or not properly torqued following the dealer's brake service during CPO preparation. I have photographic evidence of the detached caliper and brake fluid loss. INJURIES: None, but significant risk to myself and other highway drivers. FIRES: No. MEDICAL ATTENTION: Not required. CONTACT WITH DEALER/MANUFACTURER: Yes — Hyundai corporate complaint filed. I am requesting this complaint be investigated as a potential safety defect related to brake service practices during Hyundai CPO vehicle preparation.

    Horn on vehicle consistently goes out. Either goes out entirely or the volume of the horn is below a safe level. This is a known Hyundai issue and Hyundai refuses to acknowledge it on this specific model, but has acknowledged it on different models. I Have had multiple repairs by Hyundai directly, and the horn consistently keeps going out. There are sometimes in dangerous situations where I need to utilize the horn to avoid an accident and warn other drivers of danger, and I am unable to do so, and it causes dangerous driving situations. This is a known defect on multiple Hyundai vehicles in this year, but the Tucson is one of the few vehicles they will not call a voluntary recall on and NHTSA needs to be notified about this and act accordingly as a regulatory body to protect consumers and people on the road.

    I received a Recall notice around January 2026 for the trailer hitch wiring harness on my 2023 Hyundai Tucson Hybrid. For 6 months the local dealer told me there was no fix available from Hyundai. I finally received a notice informing me that parts were now available and to bring it in to dealer for repairs. I took the vehicle in for recall repairs on May 27, 2026. Instead of repairing/replacing the wiring harness, Hyundai removed the entire wiring harness making the trailer hitch which I use for my business inoperable legally. When I noticed the wiring harness missing several days later, the dealer said that was Hyundai's "fix" for the recall issue. I contacted Hyundai USA Customer Service who also told me that removing the wiring harness and replacing it with an inexpensive dust cover was the fix. They told me that sometime in the future there will be another recall to have the wiring harness replaced. In the meantime, they have taken my vehicle VIN off the open recall list, since it has been "fixed". Hyundai sold me a vehicle with a trailer hitch and now they have without my permission or prior knowledge disabled it.

    I was driving on the freeway no where near an overpass going about 65mph when the front panel on my panaromaic sunroof exploded and glass went everywhere. There is no signs that a rock could have possibly hit it. My safety was at risk because I could have crashed and broken glass rained down on me. There were no warning signs and the vehicle has not been inspected yet, but it will be.

    I am writing regarding a serious vehicle safety issue involving my 2023 Hyundai Tucson Limited purchased from on [XXX] with approximately 61,000 miles. About one month after purchase, during a drive from Pennsylvania to Florida in October 2025, the vehicle experienced multiple dangerous steering and collision-assist malfunctions in clear highway conditions. The first incident occurred in Virginia while adaptive cruise control and steering assist were active at approximately 70 mph. Within seconds, the steering wheel aggressively turned left and right, causing the vehicle to tip and nearly roll until the driver manually regained control. Later during the same trip, while making a normal lane change with the right turn signal activated, the vehicle falsely detected a collision despite no vehicle being present. The vehicle then veered left toward traffic and unexpectedly slammed on the brakes. Following these incidents, all assist sensors and automated driving features were manually disabled for safety reasons. However, the vehicle has continued intermittently triggering false collision warnings and emergency braking events with no vehicles present, creating additional near-accident situations involving surrounding traffic. I recently had the vehicle inspected by Hyundai after initially believing this may only be a calibration issue. Due to financial and scheduling limitations, I delayed service until this month, but I now understand this issue is far more serious and systemic. Two separate mechanics have advised me the vehicle has major safety-system malfunctions making it unsafe to drive. There are no reported accidents or braking issues on Carfax. I am also concerned this appears to be a widespread issue affecting this vehicle model, yet I received no notification regarding related safety concerns or recalls until conducting my own research. One mechanic stated“I’m surprised this car hasn’t killed you yet. I wouldn’t put my own kids in this vehicle." INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION
