POWER TRAIN, SUSPENSION, UNKNOWN OR OTHER
My 2017 Hyundai Santa Fe (VIN: [XXX]) was brought to Herb Chambers Hyundai of [XXX], in December 2023 to address the Underbody Corrosion Recall/Campaign (9A0). The dealer performed the preventative service. However, the remedy completely failed because the frame was already severely structurally compromised by rust. In early 2024, I relocated to [XXX] with the vehicle. Now 2026, The front subframe sub-assembly deteriorated to a hazardous point, forcing me to spend a large sum of my own money on front-end repairs caused directly by this corrosion. Currently, the rear subframe and rear suspension components are heavily corroded and structurally disintegrated. The vehicle is completely unsafe to drive, presenting an imminent risk of structural collapse and suspension failure while in motion. Hyundai's recall remedy was ineffective and merely masked the rust. The rear subframe (crossmember/cradle) and control arm anchor points are severely corroded, rusted out, and crumbling to the touch, creating an imminent risk of suspension collapse while driving. The extreme corrosion has spread to the metal fuel line the vehicle is unsafe to drive due to the advanced corrosion . Denial of Service by Local Distributor: The vehicle is currently located in the U.S. territory of Puerto Rico. I presented the vehicle and documentation to the local authorized distributor, Sojitz de Puerto Rico (Hyundai of Puerto Rico). As indicated I brought the Vehicle to MVP Hyundai Humacao (XXX) and filed a claim (# XXX) However they never sent a anyone to inspect the vehicle or process a safety claim, claiming they bear no responsibility because the vehicle was imported from the mainland, Because this is a failed federal safety campaign remedy that now poses an immediate threat to my life and public safety, INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

This email serves as a formal dispute of the warranty denial issued by [Lester Glenn Hyundai Toms River NJ] regarding the Supplemental Restraint System (SRS) passenger airbag sensor in my 2022 Hyundai Santa Fe.The dealership has refused coverage, attributing the failure to "water damage." I strongly dispute this finding and am formally requesting a Corporate Goodwill Repair Exception or a tier-two engineering review of my vehicle due to the safety-critical nature of this component.

WHEELS, FORWARD COLLISION AVOIDANCE: WARNINGS, LANE DEPARTURE: ASSIST
I am reporting severe safety risks and inspection fraud on my AWD 2020 Hyundai Santa Fe (VIN: [XXX]) caused by Universal Hyundai in Orlando. Inspection Fraud: The dealer falsified safety metrics, marking my brakes as a failing 4mm to push a $659.90 repair (RO# XXX), then passed those exact brakes at 5mm eleven days later (RO# XXX). Tire Malpractice: Mechanics over-inflated my tires to a dangerous 39 PSI and botched the alignment. This caused structural tire belt separation and severe sidewall bulges. The rear tire has suffered rapid, catastrophic deflation, dropping flat to 14.5 PSI and down to an empty 5.5 PSI. Crash & Drivetrain Risk: Operating an All-Wheel Drive (AWD) vehicle with a rapidly collapsing tire and asymmetric alignment forces the wheels to spin at mismatched speeds, creating severe friction that is destroying the internal powertrain transfer case and causing an immediate highway blowout crash risk. The service manager admitted "human error" and issued a full refund but banned my vehicle to avoid an audit. Hyundai Corporate has been notified under Case #XXX but has delayed resolution. Active consumer fraud file logged with the State of Florida under Case XXX. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

POWER TRAIN, FUEL/PROPULSION SYSTEM, ELECTRICAL SYSTEM
The vehicle will not accelerate past 30 mph on the highway. The fuel system will not engage, and the vehicle continues to run on hybrid mode which causes the battery to drain and acceleration to throttle. This occurs on all drive modes and fuel conditions.

ENGINE, POWER TRAIN, FUEL/PROPULSION SYSTEM
I was merging onto the highway and the acceleration stopped working and the vehicle would not go more than 25 mph. Had to restart car in shoulder, isue seemed to self correct but then it happened 10 minutes later stranding me in between the highway and exit ramp. This was a huge safety issue and myself and others lives were at risk. I am bringing the vehicle in for inspection but this seems to be a recurring hyundai issue. There were no warnings that came on. The auto mode on the dash went from green to an amber color. When i restarted the vehicle nothing changed. After the second time it occurred a check engine light came on.

ENGINE, POWER TRAIN, FUEL/PROPULSION SYSTEM
COMPLAINT SUMMARY: [XXX] / ENGINE THERMAL FIRE RISK / WARRANTY DECEPTION My 2019 Hyundai Santa Fe (2.4L GDI Engine) is experiencing severe powertrain degradation under the known Theta II engine defect class-action framework. On November 7, 2025, the vehicle logged a Permanent Diagnostic Trouble Code (DTC) P1326 via an independent scan, indicating catastrophic internal rod bearing wear. On XXX, the vehicle was brought to Hyundai of Milledgeville for safety recall verification. Instead of executing the mandatory corporate-directed Bearing Clearance Test (BCT) to replace the failing engine block, the service department committed technical campaign malpractice. The technician forced the 9C2 ECU Software Update directly over the locked mechanical fault to suppress the dashboard warning lights and alter the vehicle's ROM ID parameter limits. When caught via a photograph of their active GDS diagnostic tablet showing 7 historical system faults, the service manager provided a truncated printed report hiding Page 1 and omitting the critical P1326 powertrain code count to evade a warranty engine replacement. Due to these unmitigated delays, the vehicle has suffered severe consequential safety damage. The advanced engine degradation and oil consumption have flooded the exhaust system, melting the catalytic converter substrate and triggering a new DTC P042000 (Catalyst Efficiency) fault immediately after the dealer visit. The extreme engine vibrations have also damaged the transmission's torque converter clutch (DTC P074100). The dealership refused a service loaner and knowingly sent a disabled consumer and an elderly passenger away in an active, failing vehicle that presents a sudden stall-on-highway hazard and a severe thermal exhaust fire risk under extreme summer heat conditions. Hyundai Motor America Corporate has failed to provide emergency towing or alternative mobility accommodations despite a registered corporate case file.

POWER TRAIN, VEHICLE SPEED CONTROL
COMPONENT/SYSTEM: The powertrain launch control system — the Transmission Control Unit (TCU) and 8-speed wet dual-clutch transmission paired with the 2.5T engine — fails to deliver engine power in response to full accelerator input from a stop. The engine does not rev and the vehicle does not move for approximately 1–2 seconds despite the accelerator pedal being fully depressed, then power engages abruptly and violently. The vehicle is available for inspection upon request. SAFETY RISK: The failure occurs when launching from a stop into intersections and cross-traffic. In the most recent incident, I was turning left across the roadway from a stop with an oncoming vehicle approaching. I applied full accelerator and the vehicle did not respond at all for approximately 2 seconds — no engine response, no movement — leaving me stationary in the oncoming vehicle’s path. Power then engaged violently and without warning, causing the vehicle to lurch across the road. I was nearly struck. Similar events have occurred multiple times throughout my ownership; this was the closest to a collision. DEALER CONFIRMATION: Not yet inspected by a dealer. A dealer service appointment is being scheduled. OTHER INSPECTIONS: The vehicle has not been inspected by the manufacturer, police, or insurance representatives. WARNING LAMPS/PRIOR SYMPTOMS: No warning lamps or messages have appeared before, during, or after any of the events. The failure is intermittent and occurs without warning. The condition has been present since I purchased the vehicle in October 2022 and has occurred regularly throughout ownership — numerous occurrences over more than three years. No warning lamps have ever accompanied it. ADDITIONAL: Condition persists with Idle Stop & Go disabled, ruling out engine-restart delay. Same 8-speed wet DCT was subject to Recall 236 (NHTSA 22V-746) on 2021–2022 models for similar throttle non-response; 2023 excluded despite identical hardware.

POWER TRAIN
The vehicle is in limp mode and is displaying a flashing check engine light with a P1326 powertrain code. The vehicle in question is a 2017 Hyundai Santa Fe Sport equipped with a Theta II 2.4L GDI engine at 118,000 miles. Per the service campaign T3G, listed on the NHTSA website, this vehicle is covered under warranty repair since it is a Theta II engine vehicle that is displaying an active P1326 power train code. The vehicle is under he 10 Year/120,000 miles limitations of the extended warranty. The dealer just submitted to us a quote to repair the vehicle and is stating that none of the repairs listed are covered under warranty. This includes a quote to replace the engine knock sensor, which is a warranty item under the T3G service campaign’s extended warranty.

ENGINE, ELECTRICAL SYSTEM
While driving on the on ramp to [XXX] the car completely stopped and all systems shut off. There were two dash lights that flashed quickly with one being the check engine light but I did not see the other long enough to identify it. The dealership could not reproduce the issue but has the car now and is doing a more thorough evaluation. What component or system failed or malfunctioned, and is it available for inspection upon request? The engine stopped. Yes it is available How was your safety or the safety of others put at risk? Extremely dangerous as it came to a stop in the middle of the road. It was late at night so at that moment no one was behind me. Has the problem been reproduced or confirmed by a dealer or independent service center? no Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? no Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? no, the warning lights flashed on as the car died but disappeared once off.

ELECTRICAL SYSTEM
I did a navigation update as requested by the infotainment system on the Hyundai. After the update, the air conditioner would not turn on when the ac button was depressed . I took the vehicle to my local Hyundai dealer and they found the ac blower and ac button working intermittently. After further inspection, the mechanic found the multi fuses that sit on the PCB bloc had one burnt fuse that did not blow and was still hot and the PCB block had melted around where the fuse connected to it. ( Hyundai stated that they required the damaged PCB fuse, the PCB block and the harness). I'm concerned that the electrical short discovered by the Hyundai mechanic could have progress and burnt my car or my house since I keep my car in the garage. The Mechanic working for the Hyundai dealer found the burnt fuses and PCB block and kept them after replacing them with new parts. The ac was working fine until I did the navigation update and there were no warnings whatsoever.

The airbag sensor is on in the car. When I told the dealership they stated that the sensor is not covered under the warranty even though it was over by a fe hundred miles. None of the airbags will deploy if there is an accident. I don't see why a safety issue is not covered by the warranty. For the dealership to fix it, it is going to be over $800.

ELECTRICAL SYSTEM
WHAT FAILED: The 12-volt battery / no-start system. Beginning XXX, my 2025 Santa Fe Hybrid (bought new XXX suffered seven (7) sudden 12V battery failures causing a complete no-start. Each time the vehicle became inoperable with no warning, stranding my family - including two minor children (ages [XXX] and [XXX]) - and requiring roadside assistance and towing. Events: XXX (tow), 1XXX; the vehicle has sat immobilized at the dealer since XXX (~113 days). 5 dealer repair orders are attached to this complaint. SAFETY RISK: A repeated no-start can strand occupants in unsafe locations and prevent the vehicle from starting in an emergency. Once it had to be extracted from inside our garage by AAA after a 3+ hour wait; on XXX the battery died ~2 minutes after a jump-start, before I drove away. CONFIRMED BY SERVICE CENTER: Yes. AAA certified 0% state of charge at each failure; an independent OBD scan showed 4% ('Not Getting Full Done'). Hyundai issued TSBs 26-01-016H (XXX) and 26-01-016H-1 (XXX) identifying the root cause as the Fingerprint Module (FPM) failing to enter SLEEP mode when the ignition is off, draining the 12V battery - the exact defect my vehicle showed, and it applies to my vehicle. An OTA remedy released the week of XXX was never applied. INSPECTED BY MANUFACTURER: Yes - the dealer and a Hyundai field engineer inspected it. The dealer repeatedly blamed my behavior (windows down, unlocked doors, short commutes ~20 mi/day); its own draw test showed no draw, yet the diagnosis was never corrected. A Final Repair Opportunity in Jan 2026 did not fix it; failures recurred XXX and XXX As of this writing (XXX) the vehicle remains at the dealership since XXX without any status on repairs done or pending. WARNING SYMPTOMS: Sudden no-start / no-crank with no prior warning lamp, beginning XXX and recurring repeatedly.

STRUCTURE:BODY
WHAT FAILED: A panoramic moonroof shattered before delivery and was replaced by the dealer before sale. Despite the replacement, loose tempered-glass fragments remained inside the occupant cabin, including the front passenger compartment and the second-row floor where my two minor children ride. One glass fragment also tore the passenger-seat leather. SAFETY RISK: Loose tempered-glass fragments left in occupant areas create a foreseeable laceration hazard during normal vehicle use, particularly for small children riding in the second row. The presence of enough glass to tear the passenger-seat leather demonstrates that hazardous fragments remained in the vehicle after the moonroof replacement. CONFIRMED BY SERVICE CENTER: Yes. The selling dealer Hyundai of Kirkland was aware that the moonroof had shattered and was being replaced before delivery. The salesperson disclosed the moonroof damage and showed us the vehicle in the service area while repairs were being performed before sale. INSPECTED / REPAIRS: Loose glass fragments were discovered the day after delivery, prompting an immediate call to the dealer and a return visit for cleaning and inspection. Glass fragments continued to be found afterward, requiring additional follow-up visits, including a second unsuccessful repair request approximately one month later. The dealership was aware that loose glass had damaged the seat; on 09/08/2025, the salesperson directed me to repair the tear myself with clear nail polish rather than initiating a warranty repair. See file attached with evidence. No repair orders or service documentation were provided for these interior repairs. The dealer ultimately performed cleaning, third-party leather restoration, and replacement of the passenger-seat cover on 11/04/2025. Because loose glass continued to be discovered after the second repair attempt, I purchased a Prosidium protection plan for future glass-related damage. WARNING SYMPTOMS: None. This was a pre-delivery issue.

FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING, VEHICLE SPEED CONTROL:CRUISE CONTROL
The contact owns a 2017 Hyundai Santa Fe. The contact stated that while driving approximately 15 MPH on the interstate, the contact heard an abnormal tumbling sound coming from underneath the vehicle. The contact noticed an unknown object had detached from the vehicle. Upon inspection, the contact determined that the detached component was the radar sensor. The Automatic Emergency Braking (AEB) system and the adaptive cruise control became inoperative. The contact stated that the vehicle had not been involved in a crash prior to the failure. The vehicle was taken to an independent mechanic for inspection. The mechanic advised that the radar sensor could not be reattached and stated the failure was possibly caused by a crash. The local dealer was contacted, but the vehicle was neither diagnosed nor repaired. The manufacturer was not informed of the failure. The failure mileage was approximately 130,000.

ENGINE, POWER TRAIN, VEHICLE SPEED CONTROL
Hyundai Campaign 9C2 recall update: Took my vehicle in to have the Hyundai Campaign 9C2 recall update performed on the vehicle on June 9th, 2026. Since the update the vehicle is hesitant/jerky upon first drive of the day or anytime it sits more than a few hours. Occasionally it will do this while I am driving. I feel it is a saftey risk because this could cause my vehicle to abruptly hesitate without braking and cause someone to hit me, or worsetransmission to fail while at highway speeds. I took it back to the dealer that performed the required update around june 23rd 2026 and informed them of the problem caused by the 9C2 campaign update.I got the we don't know anything about it causing problems runaround. Even though it has been documented that dealers were notified of this problem. They then wanted to charge me a $100 diagnostic fee to see if it might be something else, I declined that because I know it is from this update. My vehicle ran perfectly fine and smooth before this update was applied and no CEL lights are on. I did this update because it was required to be done by Hyundai. When I started researching why my vehicle was hesitant/jerky after the update is when I found that anyone that did this update is having these same issues, and it has been happening for a while now and Hyundai corporation has done nothing to correct this problem other than tell us to sit for at least 3 minutes or more before driving it. That does not help when it does it even after driving for a bit and possibly creating transmission problems.

ELECTRICAL SYSTEM, FORWARD COLLISION AVOIDANCE: WARNINGS
I have had the vehicle in 4 times for check forward attendition warning system light keeps coming on. The first time they replaced the front camera. The situation came back after I was using the cruise control on a express way. Did not do it do it on the road but as soon as you stopped and turned the vehicle off the vehicle check forward attention warning system would come on and off and the only way to shut it off was to stop from more than 20 minutes and it would reset. Took the vehicle back 3 times and they could replicate so there was nothing they could do. The issue came back today. The check forward attention warning system light keeps going on and off. We stopped and let the vehicle sit and upon restarting the check forward attention did not reset . This time the vehicle lost all volume from the dash board. You could recieve phone but no volume. No radio volume. All the safety features that Bing are not working. Check the set up and the volume had a red 🔺️ next to the volume. 4 times into the shop for the same issur
