Warning lamp included oil for several months prior. I added oil often. No oil was ever seen under car or leaking in any way. Car had been serviced several times during the oil warning lamp warning. Nothing was ever found. I continued adding oil on a regular basis. Engine completely stopped in the middle of a busy street.

Pulled out of a parking lot into the street and there was an unusual clunking noise coming from the drivetrain of the car. Had the car towed to the dealer for diagnostics. The diagnosis from the Dealer was the transfer case splines no longer are engaging with the transmission. This problem is already known to the Manufacture and for some reason nothing has been done to address the safety issue.

ENGINE and RECALL NOTIFICATION MALFUNCTION: My 2015 Hundai Tuscon exerperienced a catastrophic engine failure/seizure while driving. Hyundai is denying an engine replacement under their extended warranty under the KSDS software update (Campaign 966) because the software update wasn't completed. However, Hyundai failed to notify me of this requirement; I purchased the automobile in Jan 2024. The KSDS recall was sent out in 2021. I recently received an official physical mailer from Hyundai Motor America titled 'IMPORTANT VEHICLE SERVICE REQUIRED' for my VIN. On that official notice, there is a dedicated section explicitly titled 'OTHER RECALLS AND/OR IMPROVEMENT REPAIRS NEEDED (associated with my VIN).' Hyundai corporate left this b ox completely blank, officially misinforming me that no other active campaigns existed for my vehicle. This represents a critical malfunction in Hyundai's automated recall and campaign notification mailing systems, which actively misleads consumers and keeps them in the dark about mandatory preservation updates. Either Hyundai's automated notification systems completely failed to inform me of mandatory nature of Campaign 966 - which is directly proven by my official printed mailer leaving the open campaign box completely blank - or the service was performed during a prior dealership visit and failed to register in the corporate database due to an administrative tracking error. I am requesting an audit of the vehicle's engine control module ROM ID to confirm if the calibration updates is physically present on the vehicle computer

ENGINE
We have a 2015 Hyundai Tucson that we bought brand new. It has 80k miles on it. The car started using oil about three years ago. The dealer recommended replacement of the catalytic converter, which we did. The car continued to use oil, and the dealership had us replace the catalytic converter two more times, so three times total. Now the problem is occurring again and they are recommending replacement of the catalytic converter for a FOURTH time. We have filed a claim with the manufacturer and have been going in circles with the dealership for months. It is our position that the repeated catalytic converter failure is caused by an underlying motor issue, which should be covered by the manufacturers warranty, but the dealer treated the symptoms instead and waited for the warranty expiration. This car is owned by my father, an [XXX] disabled veteran. He bought this car thinking it would be a safe and reliable vehicle for him to drive into his retirement years. Instead, Hyundai is repeatedly making him pay to replace the same part when it is clearly not resolving the oil consumption issue. He is being taken advantage of. Hyundai should honor their warranty.

POWER TRAIN, ENGINE
While driving on a US highway, the check engine light illuminated and the vehicle lost the ability to start/run normally, requiring the vehicle to be pulled off the road and towed to an authorized Hyundai dealership. Dealer diagnostic testing found the engine failed a bearing/performance test, consistent with connecting rod bearing wear. This failure mode — Check Engine light, DTC P1326, abnormal noise, or a no-crank/no-start condition caused by connecting rod bearing wear — is described in the manufacturer's own internal dealer service bulletin covering an engine warranty extension program for multiple engine families (Theta II MPI and Nu GDI engines) across several model years and vehicle lines. That bulletin acknowledges the failure as a known condition and extends coverage to 15 years/150,000 miles for original and subsequent owners. The failure occurred suddenly and without warning while the vehicle was in active use on a highway, creating a stall/loss-of-power hazard in moving traffic — the vehicle could not be restarted at the roadside. The dealership's own multi-point inspection performed shortly after intake confirmed engine fluid levels and oil grade were within normal range, indicating the failure was not attributable to a lack of lubrication at the time of failure. Despite this, the manufacturer denied warranty coverage for the repair, citing an inability to produce maintenance receipts for a prior period, even though the dealership's own inspection findings do not support a maintenance-related cause. This report is submitted because of the safety hazard posed by unwarned loss of engine power/starting capability while driving, and because this failure pattern appears consistent with a defect the manufacturer has already acknowledged for closely related engine platforms, raising the question of whether additional vehicles with this engine design should be included in that existing warranty/defect campaign.

SERVICE BRAKES, HYDRAULIC, ENGINE
The contact owns a 2015 Hyundai Tucson. The contact stated that while driving at 50 MPH, the vehicle stalled without warning. The engine turned over but failed to restart. The contact related the failure to NHTSA Campaign Number: 22V056000 (Service Brakes, Hydraulic). The vehicle was towed to an independent mechanic shop and then to a local dealer, where it was diagnosed that the engine seized; however, the vehicle was not repaired. The dealer advised that there was no warranty coverage. The Better Business Bureau was contacted and informed that the warranty had expired. The manufacturer was contacted, and a case was filed, but a request for repair coverage was declined due to a failure to have the recall remedy completed; however, both the contact and the previous owner were unaware of the recall. The failure mileage was approximately 118,000.

ENGINE
My 2015 Hyundai Tucson with the 2.4L engine developed a loud engine knocking sound while driving. The knocking became worse and the vehicle became unsafe to drive due to the possibility of sudden engine failure. The vehicle is currently at a Hyundai dealership and has been there for over a month. The dealership denied the warranty claim stating that a different engine component failed instead of the connecting rod bearing. This engine is part of the known Theta II engine defect issue that has caused engine failures in many Hyundai vehicles. A sudden engine failure while driving could result in loss of power, difficulty steering or braking, and could increase the risk of a crash. I am filing this complaint because the engine failure symptoms match the known defect pattern, and the vehicle may be unsafe if the issue is not properly addressed. Hyundai Tucson with 113,000 miles and failing engine. I’ve been told repairs have amounted to $10,000. I was told my car has severe engine failure and must be replaced by Hyundai of the shoals in Tuscumbia, AL. Engine failure is dangerous as a fire may start from a metal piece and also loss of control of vehicle is possible. Hyundai has denied warranty as they say the exact part in theta 2 engine settlement is not failing. I have had to complete recalls on this car since the first payment I made on it. The engine knocking began a month ago and that’s about how long the dealership has had my car.

AIR BAGS, ELECTRICAL SYSTEM, STEERING
On March 13, 2026, I was operating my 2015 Hyundai Tucson when the steering locked up, causing me to crash into a tree head-on. In the course of this head-on crash, my airbags failed to deploy. As a direct result of my airbags not deploying in a serious car crash, my head hit the steering wheel, causing a confirmed concussion diagnosis of Post Traumatic Headache and Post Concussion Syndrome in a hospital emergency room. There were no lights or symbols on the dashboard prior to the accident. My car had a prior repair for a front end collision in a body shop and a replacement of the engine in a Hyundai dealership prior to the accident. My car is currently in a tow yard. There has been no inspection of my car by the manufacturer. I have since discovered that there are a number of complaints filed with the National Highway Traffic Safety Administration ("NHTSA") from other Hyundai Tucson owners for the model years 2005, 2006, 2007, 2012, 2013, 2019, and 2023 complaining of the same defect in their Hyundai Tucsons – the failure of the airbags to deploy in serious car accidents. I believe this represents a systemic safety defect in the Hyundai Tucson airbag system that has not been addressed for the 2015 model year. This failure put my safety at serious risk and resulted in significant injuries that could have been prevented had the airbag system functioned as designed.

ENGINE, POWER TRAIN, FUEL/PROPULSION SYSTEM
On January 7, 2026, shortly after delivery of a used 2015 Hyundai Tucson (VIN [XXX] ), the vehicle experienced immediate mechanical failure while being driven, resulting in sudden loss of power and drivability. Multiple warning lights illuminated on the dashboard at the time of failure. The vehicle became disabled and left the occupants stranded roadside in Fairhope, Alabama. The exact component that failed is UNKNOWN at this time. The failure appears related to the engine, powertrain, fuel/propulsion, and/or electrical systems. The vehicle was not operable after the incident. On January 8, 2026, the selling dealership (Sandy Sansing Nissan, Pensacola, Florida) towed the vehicle back to their dealership. The vehicle has remained in the dealership’s possession since that date and is available for inspection upon request. This sudden failure created a significant safety risk due to loss of propulsion while in traffic and exposure to roadside hazards. The problem has not been independently repaired or evaluated by the consumer. No manufacturer inspection has occurred to the consumer’s knowledge. The dealer has not provided a diagnostic report or repair findings. No warning lights or symptoms were disclosed prior to delivery. The failure occurred almost immediately after delivery. The vehicle was sold and delivered by a licensed dealership. The sale is currently in dispute because the vehicle became disabled almost immediately after delivery due to this safety-related failure.

At the time of engine failure, my husband was on the offramp between 140N and 24N at approximately 8:30pm. This ramp is under construction and narrow, but state troopers stopped and were able to push the car to the side of the road. As it was nighttime, my husband and /or other motor vehicle drivers/passengers could've been seriously injured. The car did not display any warning lights or signals. The car was then towed home and then to Empire Hyundai in Fall River, where it was assessed. It was determined that there were 5 outstanding recalls on the vehicle. Hyundai fixed all, with the exception of Recall #966, which was issued and not repaired PRIOR to my purchasing the vehicle. Hyundai Corporate was contacted by Aaron at Empire Hyundai. They (Corporate) refuses to replace the engine. According to Corporate, this should've been fixed by the independent dealer or owner PRIOR to being sold to me.

Driving on interstate for approx 30min and the car stopped accelerating. We safely merged off to the side and the car completely shut off. The car would not start. We put oil in and it started up by engine light was on. We got vehicle towed 1hr back into town. We are lucky no cars were behind us to cause an accident. We are also lucky engine did not catch on fire. This happened completely out of the blue. I get my vehicle serviced regularly and serviced at Hyundai dealerships for major repairs. The engine failed us and is available for inspection. Our claim was denied by Hyundai due to my mileage being 10k over the warranty. However they installed the faulty engine so regardless of mileage this needs to be resolved.

The engine failed two years ago at 86000 miles. Hyundai replaced the engine for it to start knocking and stop working a year later. I completed all of the first oil changes, slow driving, ect. Seems like an engine problem with Hyundai itself.

I started having oil issues 3 years after purchasing my hyundai Tuscan 2015. I took my vehicle to hyundai several time all of which I was told by service guy and I quote “Hey its Hyundai, just following up so right now we have a consumption issue. It is currently 2.5 quarts low. The tech recommends re doing the oil change and returning in 1000miles and recheck. When you return and we see that the oil level is more than a quote low then we would have you reduce the service interval from 5000miles to 3000miles, let me know if you have any questions. I had many questions and also wanted to know why it was my responsibility to do all these things if they know the engine is faulty. Had another diagnostic and the code P1326 populated. That means indicates an issue with the Knock Sensor Detection System (KSDS), often pointing to actual engine knocking caused by worn connecting rod bearings, but also potentially to a faulty knock sensor, wiring problems, outdated ECM. The Theta II engines are documented to have clogged oil galleys, preventing proper lubrication and causing premature wear. They do everything the can NOT to fix the issue even with a lifetime warranty on that engine.

Without any notice, the crankshaft seized while driving 55 mph on the highway. We were on a highway with one lane in each direction and a shoulder. No warning lights appeared until after the engine failed. We were barely able to coast to the shoulder at the time. The incident blew a baseball size hole in the engine. The vehicle was towed to over 60 miles to Noller Hyundai of Lawrence, Kansas. The repair was paid for under the Hyundai warranty without me providing any maintenance records. The engine is not in our possession for you to inspect, but I'm sure you could reach out to the dealership where it was replaced.

ENGINE, POWER TRAIN, FUEL/PROPULSION SYSTEM
On [XXX], my husband and I were driving on [XXX] (Highway) in the slow lane, when the engine shutoff without any Service engine light warning. It was frightening because an tractor trailer was directly behind the car as we lost power. There was no sounds of engine parts knocking or pinging when the problem occurred. The only thing was observed was (two) 2 puffs of smoke seen from the tailpipe, witnessed by my son who was following behind in his vehicle. The vehicle was not able to start after shutdown and had to be towed to my home. We purchased a new battery after assuming battery failure--with no resolve. The vehicle was towed to(two) 2 repair shops with the same conclusion: Seized Engine After checking Open Recalls on my vehicle, I contacted Hyundai to check for assistance. The vehicle is now at the Hyundai dealership in McDonough, Georgia for inspection. I am thankful that my husband and I were not injured or laying in a Morgue after this frighten ordeal on the highway when the Engine suddenly shutoff/Seized.

The engine uses about 3 to 4 quarts of oil before a oil change the it will go in limp mode. I have to get it rest and then add oil for the engine to run right. Also transmission don't want to shift 3 to 4 gear it will be 35 mph to 65 before it shifts. When the car goes in limp mode I lose power going up a hill and almost got rear ended. They won't do anything do to its a used car. No lights came on the dash till it acts up.

--->While I was driving my hyundai tucson engine seized (-engine model (lm) 2.4l theta ii--> 63,664 miles). Yes, the vehicle is available for inspection. ---> As I said before I was driving in a express way when the incident happened. My car just stopped working out of a sudden and I had to take the side road by applying a much force effort from myself not to get hit by several vehicles behind. When I finally managed to step aside, I sensed some sort of smoke smell. And also all warning lights from car dashboard came up with no prior lamp alerts before this incident. ---> I took the vehicle to the nearest repair shop called Sam's certified auto repair. And there it was diagnosed that the vehicle engine was seized. So i inmediately called the dealer and the asked me to tow my SUV. There they diagnosed the vehicle with a seized engine too. From there on I found out that these vehicle i bought have a recall and that the this engine model has a major malfunctioning manufacture issues. Then I tried to get an authorization approval for a new engine but it was denied because they stated that I have a savage title.
