VISIBILITY/WIPER
WIPERS STOP WORKING. THEY WILL FREEZE AND STOP MOVING ACROSS THE WINDSHIELD. SO FAR I CAN FIX THE PROBLEM BY TURNING THE WIPERS OFF AND THEN BACK ON. MY CONCERN IS THAT MAY NOT WORK IN THE FUTURE. ALSO, IN HEAVY RAIN AN ACCIDENT MAY HAPPEN BEFORE I CAN RESTART THE WIPERS. I BROUGHT THE CAR IN TO THE DEALERSHIP, BUT THEY COULD NOT FIND ANYTHING WRONG.

ENGINE AND ENGINE COOLING:EXHAUST SYSTEM:EMISSION CONTROL:CATALYTIC CONVERTOR
The contact owns a 2017 Hyundai Tucson. The contact stated that while driving at undisclosed speeds, the vehicle was consuming an excessive amount of engine oil. The contact stated that oil was frequently added to the engine. The vehicle became inoperable. The vehicle was towed to a dealer, where it was diagnosed and determined that the catalytic converter needed to be replaced. The catalytic converter was replaced; however, the failure persisted. The vehicle was returned to the dealer for inspection, and the catalytic converter was replaced a second time. The vehicle was repaired; however, the failure persisted. No additional repairs were performed. The manufacturer was notified of the failure. The approximate failure mileage was 86,000.

ELECTRICAL SYSTEM
The center infotainment display flickers then goes fully blank while driving, caused by a defective coaxial cable with undersized shield width (Hyundai TSB MC-11010978-0001). When the screen blanks, the backup camera also stops working, leaving no rear visibility when reversing. Audio and head-up display still function. The vehicle and component are available for inspection. Safety risk: the display and backup camera fail without warning during normal driving and while reversing, eliminating rear visibility and risking striking pedestrians, objects, or vehicles. Failures are triggered by heat, potholes, and braking—routine conditions—so the loss is unpredictable. The dealer reproduced and confirmed the problem, identified the TSB cable defect as root cause, and made multiple failed repairs: tightening clips, replacing the wiring harness, replacing the head unit, and performing the TSB repair. The identical symptom returned after the TSB fix. The vehicle has been inspected only by Hyundai's authorized dealer through these repeated visits—not by police, insurance, or a field engineer (field engineer involvement is being requested). No warning lamps or messages precede the failure. The first symptom is the screen flickering, immediately followed by the screen going blank and the backup camera failing. Symptoms first appeared at 10,717 miles on 07/23/25.

ELECTRICAL SYSTEM
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.

The instrument cluster intermittently goes completely black while driving, causing loss of the speedometer, warning lights, and gear indicator. The failure occurs randomly, including while the vehicle is in motion. The symptoms match the known 2026 Hyundai instrument‑cluster recall, but my VIN is not currently included.

SERVICE BRAKES
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.

ELECTRICAL SYSTEM, UNKNOWN OR OTHER
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.

FORWARD COLLISION AVOIDANCE: WARNINGS
There was a recent recall for the forward collision cameras that were causing breaking issues. This happened 4 or 5 times with the vehicle slamming on the brakes violently. I took it into Tustin Hyundai last month and had the software recall applied. The issue happened again on the 55 highway on June 20th at 6pm going approximately 35mph. Vehicle in front of me hard braked and applied brakes under control coming to a stop when the car took over and slammed on the brakes skidding the vehicle sideways

FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING, FORWARD COLLISION AVOIDANCE: WARNINGS
While vehicle was at dealership service department for an oil change, dealer performed FCA (Forward Camera Assist) Update recall. After leaving dealership, the vehicle displayed several warnings. "Check Emergency Stopping function", "Smart Cruise Control disabled", and "Forward Safety system limited". This never happened previously, and these safety systems became disabled within two miles after leaving the dealership where the update / recall to them was performed. The recall was intended to prevent unnecessary emergency braking. Somehow the update resulted in completely disabling that safety system. Invoice from dealership shows 17012 miles out, and photos of dashboard show 17014 miles. Return appointment for them to look at this is three weeks out. Contacted Hyundai customer service to report this.

The 2019 Tucson has 60,413 miles. My daughter drives it very low mileage - a couple of miles a day back and forth to school. Friday she was driving and the car lost engine power and it stopped driving. No warning lights. There was a cloud of smoke and it smelled like burning plastic. She was on a busy road but pulled over and quickly exited the vehicle. I had it towed and the mechanic says the engine oil was empty and the engine has seized. We do regularly scheduled oil changes. No lights or warnings and the car just stopped in traffic.

ENGINE
I am reporting a serious safety issue involving diagnostic code P1326. My vehicle developed engine knocking and little to no acceleration and appeared to enter a reduced-power or limp-mode condition while driving. This made it difficult to merge, maintain speed, and travel safely in traffic, creating a risk of collision or becoming stranded in an unsafe location. Based on publicly available Hyundai materials, code P1326 is associated with the Knock Sensor Detection System (KSDS) and may indicate abnormal engine vibration, possible bearing-related engine damage, and reduced-power operation. Those materials also indicate that certain vehicles were eligible for software updates, inspection, and possible engine repair or replacement. I request that this issue be documented as a safety complaint and that the dealership perform a full diagnostic inspection, determine whether my vehicle qualifies for any applicable campaign or warranty extension, and provide appropriate repairs.

The Integrated Charging Control Unit (ICCU) failed on my 2025 Hyundai Tucson PHEV at approximately 6,600 miles. The failure manifested through multiple concurrent symptoms. First, the vehicle displayed a "car not charging" warning light and completely refused to accept an electrical charge when plugged into a charger. Simultaneously, the Check Engine Light illuminated on the dashboard. While driving, the vehicle experienced a sudden and unsafe loss of propulsion power when attempting to drive uphill. This sudden drop in power created a hazardous driving condition in traffic. The vehicle was taken to an authorized Hyundai dealership, where technicians ran diagnostics and officially confirmed that the ICCU had failed and required a complete replacement.
