2016 HYUNDAI TUCSON Complaints

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)

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

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)

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

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.

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.

I have diligently maintained the vehicle with all scheduled services performed at the Rick Case Hyundai dealership. My maintenance records show a documented history of proper oil changes and other essential services. These records confirm that the vehicle was regularly serviced according to the manufacturer's recommendations. The diagnostic report from the dealership indicates bad piston and heat marks, but there is no evidence to suggest this was caused by a lack of proper maintenance.

I am filing this complaint regarding my 2016 Hyundai Tucson due to excessive oil consumption. The vehicle burns oil at an abnormal rate, requiring me to add approximately one quart of engine oil every one to two weeks, even though the vehicle is driven very infrequently. This condition poses a serious safety risk because the engine could run low or completely out of oil while the vehicle is in operation, potentially causing sudden engine failure. This vehicle is used to transport my family, including children, which puts their safety at risk. I have taken the vehicle to Hyundai dealerships multiple times for full ispection , but no defect, warning, or solution was ever identified or communicated to me. There have been no warning lights or messages on the dashboard to alert me of low oil levels or engine problems, increasing the risk of failure without warning. The problem is ongoing and repeatable, and the vehicle and engine are available for inspection upon request.
