2016 Hyundai Tucson

I had ANOTHER door latch lock assembly fail on my 2016 Hyundai Tucson. There was a TSB for this issue that the dealership said expired for my vehicle three months ago. They wanted a $200 diagnostic fee for a total repair of close to $1000. They confirmed it was another door latch lock assembly, although I’m not sure how because the door would not open from the inside OR the outside. When the rear passenger side assembly failed a week ago, my kids were stuck in the back of the vehicle. This is a potentially dangerous issue that Hyundai seems to be aware of. If the front driver’s side goes at the wrong time, and I am not able to open my door, it could have disastrous consequences. I could become trapped in my car in the event of an accident, fire, etc. Hyundai needs to recall all door latch assemblies and just replace them all free of charge. It’s ridiculous that it’s a guessing game of when they might stop functioning properly and potentially trap you inside the vehicle.

I am writing regarding the diagnosis provided for my vehicle [XXX] . I was informed today that the engine failure is being attributed to a "water hose failure" rather than the engine defects covered under the active safety recall/settlement regarding Connecting Rod Bearing failure. As there were no coolant leaks before or after the vehicle was towed to your dealership. I am formally requesting a re-evaluation and more detailed evidence. Given the known history of these engines seizing, I need to ensure this diagnosis is absolutely correct and not a symptom of the internal defect. I request the following information be provided immediately: 1. Evidence of Overheating: Did the vehicle store any specific "overheating" codes in the ECU prior to the engine shutting off? 2. Oil Pan Inspection: Has the oil pan been removed to inspect for metal shavings or debris? If the connecting rod bearings failed (the recall issue), there will likely be metallic debris in the oil, regardless of the condition of the water hose. 3. Bearing Clearance Test (BCT): Was the mandated Bearing Clearance Test performed? If not, I request that this be done, or that a teardown be performed to inspect the rod bearings specifically. 4. Causal Link: Can you provide evidence that the water hose failed causing the engine to seize, rather than the engine seizing causing a pressure spike that damaged the cooling system? I have no transportation to work and school. They would not honor a loaner. This has happened since Decemeber of 2025. I await your written response with the requested photos and technical data. My case # with Hyundai Consumer Affairs # XXX Please provide: All relevant photographs Freeze-frame and ECU data Technician diagnostic notes Results of oil pan inspection and/or BCT (if performed) Any physical evidence supporting the stated cause of failure I request this information be sent in writing at your earliest convenience.

Vehicle: 2016 Hyundai Tucson Issue Category: Engine / Powertrain / Vehicle Safety Complaint: I am reporting a serious safety issue involving my 2016 Hyundai Tucson equipped with a Theta II engine. My vehicle first displayed an engine oil warning light. I immediately took the vehicle to an authorized Hyundai dealership, where I was charged approximately $500 for an oil change and diagnostic testing. I was told there were no issues with the vehicle. Within approximately 20 miles of leaving the dealership, the vehicle suddenly entered limp mode while driving and displayed diagnostic code P1326. This created a dangerous situation as the vehicle lost power unexpectedly. I returned the vehicle to the dealership, where a software update was performed. However, within another 20–30 miles, the exact same issue occurred again, with the vehicle entering limp mode and triggering code P1326. Hyundai has now refused to repair the engine under warranty and is attempting to attribute the issue to a catalytic converter problem, despite the presence of code P1326, which is associated with engine rod bearing failure and is part of a known defect affecting these vehicles. This condition presents a significant safety risk, as the vehicle can lose power suddenly while driving, increasing the risk of a crash. I believe this issue is directly related to the known Hyundai Theta II engine defect, which has been the subject of recalls and a class action settlement. I am requesting that NHTSA investigate Hyundai’s handling of these failures and their refusal to repair vehicles experiencing known engine defects that pose a safety risk

The transmission began slipping and hesitating within days of purchase. The vehicle intermittently fails to accelerate when pressing the gas pedal, especially when pulling into traffic or crossing intersections. This creates a serious safety risk because the vehicle does not respond when needed, leaving me exposed to oncoming traffic. The issue is intermittent and does not always trigger warning lamps or fault codes. The problem has been reproduced multiple times by me while driving under normal conditions. The selling dealer performed only a brief test drive and stated they could not duplicate the issue, but the hesitation and failure‑to‑accelerate continue to occur. The vehicle has not yet been inspected by Hyundai, but the symptoms match known issues with the 2016 Tucson’s dual‑clutch transmission and TCM logic. There were no warning lights prior to the failure, and the symptoms first appeared within the first week of ownership. The vehicle is available for inspection upon request.

"On [XXX], my 2016 Hyundai Tucson (VIN [XXX] ) experienced severe engine power loss and mechanical noise under load while driving uphill, creating a dangerous safety situation. This occurred 2 days after a dealer visit (February 19, 2026) where an open KSDS Service Campaign (TSB HCE22-14-E600-TL, Issue 10D021) — directly related to engine monitoring — was left incomplete. The dealer subsequently denied an engine evaluation citing mileage over 150,000, despite the open campaign having no mileage restriction and despite a prior verbal commitment to cover repairs. Multiple follow-up attempts by phone, email, and WhatsApp have been ignored." INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

My car had a KSDS knock sensor detection system campaign 966 installed in 2022 specifically to active if having rod bearing wear. Towed my car to Hyundai under the TXXM warranty and they said my bearing clearance was ok and i need new lifters and timing chain cost for repair $2900. I have asked for the full rod bearing wear test report and they will not provide it. They have had my vehicle for 20 days now and I am out of work on disability. Hyundai service center is generally expected to provide you with a report following a rod bearing wear test (often referred to as a Bearing Clearance Test or by a related service campaign, such as T6G or TSB 21-EM-004H). Here is what you can expect regarding reports and documentation: Documentation of Results: The dealership should provide a copy of the results, specifically noting if the bearing clearance passes or fails. Proof of Inspection: If the test is performed under a recall or Service Campaign (e.g., Campaign 966, 982, or T6G), they are required to document the inspection, which you can request for your records. Evidence of Damage: If the test results in a failed diagnosis, technicians often take photos of the engine internals, such as metal flakes in the oil pan or excessive wear, which are used to support the warranty claim. If the Test Passes: If your vehicle passes, ask the technician to print a copy of the results. If the Test Fails: A formal diagnosis of rod bearing failure, confirmed by this test, is required for engine replacement under the extended 15-year/150,000-mile warranty.

Excessive oil consumption caused engine failure on December 17, 2025. My truck stopped and I was stranded on Highway I55 South for 4 hours. Hyundai and the Extended warranty has denied fixing my truck. It is still at [XXX] Hyundai as of today. Hyundai’s failure to properly diagnose or repair this issue when it was first reported under warranty has caused financial burden, diminished vehicle value, loss of use and inconvenience, and emotional distress and stress. This is a legitimate safety concern. I am demanding resolution of an ongoing excessive oil consumption defect in my 2016 Hyundai vehicle. This defect began while the vehicle was under warranty and has continued despite proper maintenance and compliance with Hyundai’s service requirements. I expect Hyundai to honor its legal and contractual obligations without further delay. Please contact [XXX] [XXX] Hyundai) @ [XXX] for details regarding repairs, oil consumption tests, etc. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
