2016 Hyundai Tucson

Took vehicle to dealership and had it diagnosed for the electrical system faults cause all the dashboard warning lights came on. Shop said it could be bad vacuum pump.

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

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.

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

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.

No check engine lights came on! The entire car caught fire and was engulfed in flames!!! Driver could have been killed!

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. Hyundai - Recalls +3 This is a safety issue without the full rod bearing report to consumer.

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.

The contact owns a 2016 Hyundai Tucson. The contact stated that the check engine warning light was illuminated, and there was a ticking sound coming from the front of the vehicle. The vehicle was taken to Auto Zone, where a mechanic diagnosed the vehicle with a knock sensor failure. The knock sensor was replaced. The mechanic informed the contact that the vehicle was included in Manufacturer Campaign: CS966 for the transmission control module (TCM). The vehicle was taken to the dealer, who confirmed that the vehicle was included and the software update was performed. After the vehicle was repaired, the check engine warning light was no longer illuminated; however, approximately 30 minutes later, the vehicle failed to exceed 35 MPH, and the check engine warning light started flashing. The vehicle was returned to the dealer, and the contact was informed that the software update caused the vehicle to enter LIMP Mode to protect the engine. The dealer informed the contact to drive the vehicle for 30 days or a total of 500 -1000 miles, and if the vehicle continued to enter LIMP Mode or failed to operate as needed, to return the vehicle for the engine to be replaced. There were no additional repairs performed. The manufacturer was not informed of the failure. The failure mileage was approximately 125,000.

The car has been diagnosed with internal engine failure by both an independent service center and a dealership service center. The issue was described as a rod timing issue causing knocking, leading to failure of the engine. A light was not on for a majority of the issue but did start flashing before car became completely undrivable. The car was sold to me with this issue and has been driven for nearly 3 years with a power loss issue that was dismissed as turbo lag or other issues. Driving a car with this issue that does not alert with a check engine light is a major threat to driver and passenger safety as it can result in engine seizure and vehicle fires. The engine issues began at the least before 58,000 miles, with total failure occuring at roughly 96,000 miles. Hyundai is known for this issue, particularly in turbo model engines. Only once during ownership of the car did the check engine light come on prior to engine failure. When checked, it was described as a catalytic converter issue. The service center also did an oil change on the car, and the light went off. The check engine light did not come on again for more than a year. The check engine light did not come on until after the issue was diagnosed by the independent service center it was taken to in January 2026.

The engine, specifically cylinder # 3, has had a catastrophic failure at 114,000 miles. Engine repair shops and engine experts have determined the only fix is a complete engine replacement. Cost estimates are $8500 for a new engine + labor estimated at $2000. Scrap value is estimated at $1000 - $1500 The dealer from whom we bought the car in late 2015 said it is out of warranty. This is unacceptable. Please, please issue a recall on the engine of this vehicle. The vehicle is available for inspection if requested. Failure was catastrophic Problem has been confirmed by engine experts The car is not drivable to a manufacturing facility The engine has not been inspected by police nor our insurance company There we no warning lamps or messages Symptoms include shuddering at initial acceleration beginning at 75,000 miles Dealer said there was no problem and recommended and performed a transmission fluid change

On my husband's way home from work he explained to me that the car had a "hiccup" and then an engine light blinked on, then it died at an intersection. He was pretty close to home so he got it started again and drove it home. He replaced spark plugs and coil packs and it still had a misfire. We took it to an auto repair shop where they did a scan and told us it had a dead hole in cylinder 2 and that it needs a full engine replacement. The car also had an oil change just before Thanksgiving. My husband checks oil regularly and added a quart a month before the oil change and it seems to consume more oil then it should.

Window regulator and motor have failed due to plastic gears stripping out. I have replaced my two front windows in 2024 at $1063 a window. This week I had both rear windows fail allowing the windows to drop down unexpectedly. I was able to manually pull the windows up and tape them. I was supposed to receive a call from Hyundai twice this week about getting these covered under a recall since all four has failed, but they have failed to contact me.

Numerous issues with this vehicle. Now, when having oil change, told by the hyundai service center that it is using excessive oil and may need a new engine. In researching this problem, have discovered hyundai has had several problems with excessive oil consumption in their many of their hyundai vehicles, including the 2016 Tuscan

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)

Drove into a parking space, with the foot pressing on the brake pedal, the car suddenly and without warning rapidly accelerated uncontrolled causing the vehicle to accelerate past the end of the parking space causing property damage.

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.
