2016 HYUNDAI TUCSON Complaints

Driver side door lock actuator failure yesterday. 4/10/26 Purchased this car 8/15/25 was not told there was a problem and recall

Three power window regulators have failed on my 2016 Hyundai Tucson within a six-month period. The front driver and front passenger windows both failed first and required replacement. The rear driver-side window has now also failed and is currently stuck in the open position. When the failures occur, the window will move up slightly but then drop back down or will not stay closed, indicating a failure of the regulator mechanism rather than normal wear. The fact that multiple window regulators have failed in a short period suggests a defect or premature failure of this component. This creates a safety concern because one window is stuck open, exposing the vehicle interior to weather, reducing security, and potentially affecting driver visibility and safe operation. This appears to be a known issue with this model year, but my vehicle is not included in any recall.

The contact owns a 2016 Hyundai Tucson. The contact stated that while driving at an undisclosed speed, there was an abnormal sound coming from the engine compartment. Moments later, the vehicle stalled after driving a very short distance. An independent mechanic arrived at the residence to perform an oil change and found metal shavings inside the oil. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 94,000.

All dash warning lights are on and dash lights have a intermittent bright light surge. Hard to shut off engine and have to disconnect battery for electric power to shut off. Very noticeable hesitation in acceleration starting to drive

The contact owns a 2016 Hyundai Tucson. The contact stated that while attempting to buckle the driver's side seat belt, the seat belt failed to buckle securely, and the seat belt failed to retract as designed. The contact had not attempted to pull on the seat belt and the seat belt was unable to buckle securely. The contact had not taken the vehicle to a local dealer or independent mechanic. The vehicle was not diagnosed or repaired. The local dealer was contacted dealer and referred the contact to the NHTSA Hotline for assistance. The manufacturer was not informed of the failure. The failure mileage was 78,361.

Hyundai Tucson Sport 2016 GDI engine. I am the original owner of this truck I have taken care of this truck so much it being my first brand new purchase. No oil leaks NOTHING! When I first purchased the vehicle I noticed that it would stall when I would accelerate but did not think too much of it since it was brand new. A few years passed started to notice frequent oil changes were supposed to be made. Another few years turbocharger went out had to get it replaced. The engine consumes so much oil at first I thought it was because the turbocharger was out so when I got it fixed I thought that would fix that issue and it didn’t. I got an oil change March 2, 2026 and on March 21, 2026 I was on the highway and the truck started to shake really bad I exited the highway went straight to the oil place they said I had no oil on the dipstick I got ANOTHER oil change (expensive) and when I turned on the car to leave the car shook again and the engine light was flickering on and off and finally stayed on the dash board. Barely made it home. Got a tow truck to tow it to Hyundai dealership they told me they will not see it unless I pay the diagnostic fee of $200 and even then they think it’s the engine with everything I described to them. They said since there are no recalls on the Tucson that Hyundai will not do anything for me I would have to pay out of pocket for everything. Had to pay the tow truck again to tow it to my house ($250). My car has all the symptoms all the other cars have that they have recalled. This is a huge safety issue because i drive on the highway a lot and everyone knows a car with no oil is extremely dangerous.

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. Thank you for your attention to INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U

Three window regulators have failed, leaving the windows completely useless. The first occurring in heavy rain and making it impossible to close. This is an issue reported countless times online.

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
