The engine consumes oil which is a known problem at Hyundai with the Tucson for the year 2020. The car has ~51,000 miles on it. When we took the car to the dealer at which we bought the car they diagnosed that the engine was burning oil. We were told that the engine is covered by standard warranty (10 yr. 100,000 miles). There is a process Hyundai has established for engines suspected of having this issue - first we had to have them check the oil and engine and then we had to drive the car 1000 miles and bring it back to them. When we brought it back they confirmed the the engine was consuming oil. They asked us to provide our maintenance records on the car (oil changes). We were able to find evidence of 5 oil changes but we know the we changed the oil on the car every 3-5k miles as we always do. The next step in the process is a combustion chamber cleaning which costs $1400 which would normally be covered by warranty but since we did not have all records of oil changes they will not cover it so we are being told we have to pay the $1400 out of pocket and also the the cleaning is not assured to fix the issue with the engine. If it fails to fix the issue the car will need a new engine which Hyundai is telling us they will not do under the warranty and it will be our financial obligation ($10-15k additional paid by us). It is clear that Hyundai is trying to shirk their warranty obligation to us. So we are stuck - we have to pay out of pocket for a service that may not resolve the issue and if it does not the car needs a new engine. If we sell the car back to the dealership they will only pay us $6000 when the car with a good engine is worth $15k. We take our obligation of regular maintenance seriously and have been loyal buyers at this dealership for >20 years never having an issue with proper maintenance. We think it unconscionable that Hyundai is leaving us holding the bag for a problem they know exists with theses engines.

Oil consumption is at an all time high. At last oil change I had milage 71847 on 3/8/26. I checked my oil on 4/26/26 with 73182 miles, oil was at the add mark on the dipstick which means 2 quarts was gone from my engine at about 1500 miles put on my car since the oil change. Upon reading up on this issue, it is a wide spread issue with several Hyundai models. I bought it used at a car dealship when it was only a year old, so the warranty is only for the original owner. I still owe $3400. 00 on this car and I am afraid the engine will go before it is paid off.

Sitting at a red light the vehicle seemed to almost stalled then lunged forward about eight feet almost colliding with the vehicle in front of me. To my knowledge the vehicle has not been inspected by the manufacturer nor has the problem been reproduced by a dealer or independent service center. To my knowledge there were no warning lights, messages or symptoms. I am somewhat unfamiliar with this vehicle since I've only owned it for 5 days. I picked it up on 4-25-26.

My hundai tuscon 2017 was making a whurring sound on the highway, at which time my rpm's were not going over 3. As I was looking for places to pull over on the highway, I heard a loud 'pop' and then my engine started smoking and an intense rattling ensued to where I could hear a series of parts drop out of the bottom of my car. My car began smoking and the engine completely stalled just in time for me to make it to the side of the road. I took it to a local shop for repairs and they showed me three holes in my engine.

My 2017 Hyundai Tucson is experiencing dangerous, sudden engine stalling, which are symptoms directly matching service campaign t1b. These critical safety issues surfaced following a total engine replacement in June 2025. Despite the vehicle being within the 12-month/12,000 mile workmanship warranty, the dealership is refusing to honor this coverage or offer goodwill assistance. My claim is based on a documented pattern of physical and technical negligence: - failure to update software: the dealership failed to perform the mandatory ecm/tcm software integration (campaign t1b) during engine swap, which is required to prevent the exact stalling I am now experiencing. - dismissal of warning lights (code p0456): one day after the engine replacement was “completed,” I returned to the dealership because the check engine light illuminated with code p0456. This was dismissed by the service provider without a proper diagnostic resolution, despite being a direct indicator of improper vacuum line reconnection during the engine installation. - mechanical negligence (coolant leak): post-engine swap, the vehicle developed a coolant leak, which was a direct result of improper reassembly. Additional proof of the lack of due diligence during the repair. The lack of follow-through, combined with the dismissal of a life-safety defect and poor physical workmanship, suggests a total failure in the case management process. I am urgently requesting assistance to resolve this hazardous situation.
2019 Hyundai Tucson experienced catastrophic engine failure, including internal damage. Vehicle previously had Hyundai campaign 966 (engine monitoring logic) completed. Despite this, engine failed without sufficient warning. Concern that prior campaign did not prevent engine failure.
See attached document for complaint.
Vehicle stalled approximately 15 times between April 17 and may 4, 2026, including once on interstate xxx at approximately 50mph with minor children ages [xxx] and [xxx] in the vehicle. The oil and battery lights illuminated simultaneously at each stall. Diagnosed as abs module failure first, then left front wheel speed sensor failure on the 2nd occasion, both confirmed by a Hyundai dealership. Multiple warning lights illuminated, including check blind spot and anti lock brake system messages on the dashboard but no error codes following the 2nd repair. The vehicle has been inspected and repaired twice by the manufacturer’s dealership with a 3rd repair currently pending as of may 11, 2026. An open case has been filed with Hyundai motor America regarding this issue. Issue remains unresolved and the vehicle is still at the dealership. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

Knocking noise in motor and metal flakes in the oil. Called local dealership. They report no recalls for this issue.
Approximately one month ago I had a high pressure fuel pump installed in my 2018 Hyundai Tucson. While driving on the highway, about ten minutes from home, my car suddenly burst into flames. There were no warning lights in the cockpit. There was no smoke in the cabin. Another motorist flagged me down. I got out of the vehicle just in time for it to become fully engulfed in flame. It burned down on the highway. Police and fire responded. Insurance is investigating. If I was inside the vehicle, I would have certainly died.

The contact owns a 2017 Hyundai Tucson. The contact stated that while driving at an undisclosed speed, the engine made a ticking sound. No warning light was illuminated. The vehicle was taken to the dealer and was repaired under NHTSA campaign numbers: 20v543000 (service brakes, hydraulic) and 21v727000 (engine); however, the failure occurred after the recall repairs were performed. The contact stated that while driving at an undisclosed speed, the vehicle stalled and failed to accelerate above 40 mph. Additionally, while depressing the accelerator pedal, there was an extremely loud ticking sound coming from the engine. The check engine warning light was illuminated. The vehicle was taken back to the dealer; however, the vehicle was not yet diagnosed or repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 67,700.
On Monday, [xxx], I was traveling northbound on [xxx] headed towards roanoke from salem at an approximate speed of 65 mph. At approximately mile marker [xxx], before the exit to [xxx] , the vehicle started to lose power rapidly, and the car began to go into what I perceived as "limp mode" and was shaking. In an attempt to not be stranded on one of busiest and most dangerous highways in va, I was able to get the vehicle pulled onto the shoulder of the on ramp of [xxx] going towards roanoke. By this time, the vehicle had completely lost power and was not able to move, so I shut it off. At this point, I was stranded on the side of [xxx] , and extremely busy highway. This was a great safety concern, as the shoulder was very narrow and cars were moving through 2 lanes of traffic with many drivers exceeding 75 mph. My own personal safety was greatly jeopardized with the failure occurring with absolutely no warning and shutting off the car while on [xxx]. The vehicles failure was catastrophic and was undriveable. The vehicle was then towed to a nearby shop. There were no warnings whatsoever before this failure occurred. No engine lights were on beforehand, and the car drove completely fine and has been comprehensively maintained its entire life. The problem of a rod-bearing failure has been confirmed with a local service center, one stop automotive in vinton. The service department at southern Hyundai based in roanoke va is refusing to look at the vehicle and submit a claim to Hyundai USA , even though the failure has already been confirmed by a licensed mechanic.

The oil consumption issue has begun. At about 75k miles, my 2018 Hyundai Tucson 1. 6l turbo is burning oil at an insane rate. And there is no indicator of it occurring (no codes or anything on the dash) until it's too late. Hyundai is now well known, and aware, for this problem and it is a catastrophic safety issue because of the possibility of the engine seizing and disabling the vehicle. It isn't negligence on the consumers part either, especially when timely and consistent oil changes are being done. *note* my vehicle has had the transmission (6 speed dual clutch) replaced at around 30k miles and is having the same issue again (at 75k miles). So first the transmission and now the engine!.
Car is a gas hybrid (not plugin). 3 occurrences over the last couple of months. Car emits a warning sound and a message on the dash says "check hybrid system. Stop safely". Basically right after this message the car starts losing power and stops. Doesn't matter if on freeway or not. You need to find a place to pull over or you stop traffic wherever you are. Looks like hybrid battery is completely drained. Can not be re-created. Dealer has it now for the 3rd time. Dealer in the past have not been able to find cause/cure since this issue is not posting any errors to the onboard diagnostic system. Temporary 'fix' is to power off car, and power back on. Looks like this is a 'known' issue though as its being reported by quite a few people online.
The contact owns a 2017 Hyundai Tucson. The contact stated that while starting the vehicle and driving at an undisclosed speed, there was an abnormally loud grumbling sound coming from the engine. There was no warning light illuminated. The contact stated that the vehicle unexpectedly entered limp mode. There was no warning light illuminated. The vehicle was towed to the dealer but was not diagnosed or repaired. The manufacturer was made aware of the failure and informed the contact that documentation of previous oil changes was required. The contact stated that the manufacturer accused the contact of a lack of maintenance, which was associated with the engine failure. The failure mileage was approximately 98,000.
Vehicle has failed to start with no warning lights (completely blank infotainment screen) and no sounds when start button is pressed. Vehicle also completely shuts down when stopping in traffic and takes several attempts at restarting before the vehicle actually starts and able to move. This is a severe life threatening or serios injury situation that Hyundai seems to have no interest in solving. Incidents have been video when safety is not an issue.

On March 21st, while driving my Hyundai vehicle, I noticed the vehicle began making a ticking sound. After stopping the vehicle, it slowly began catching on fire. The fire ultimately spread and resulted in the vehicle becoming a total loss. This created a serious safety concern and placed me at risk. I later learned there was a recall associated with the vehicle. However, I never received any recall notices because Hyundai reportedly had the wrong address on file. Had I been properly notified of the recall and potential safety risks, I would have done everything in my power to ensure the vehicle was inspected, repaired, and safe to drive. Because I was unaware of the recall issue, the vehicle continued to be operated without my knowledge of the potential danger. The incident caused significant financial and transportation hardship, including loss of reliable transportation and additional financial strain. Hyundai later reached a determination regarding the matter, but I remain concerned about the serious safety risk and the fact that I did not receive proper recall notification before the incident occurred. I am submitting this complaint because I believe the recall notification process and handling of this matter should be reviewed further due to the serious safety risk involved.
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.

The 2. 0l engine catastrophically failed during normal highway driving, consistent with a thrown connecting rod. The vehicle suddenly lost power on a roadway with tractor-trailer traffic. The driver and a child passenger narrowly avoided being struck by a semi-truck before the vehicle could be brought to a safe stop. No prior warning lamps, no check engine light, no abnormal noises, and no indications of any kind preceded the failure. The failed engine is currently at a Hyundai dealership and is available for inspection. The dealer has confirmed catastrophic engine failure and submitted an engine replacement request to Hyundai motor America. Hyundai motor America declined the engine replacement request, citing incomplete status on service campaign 966 (knock sensor detection system update for connecting rod bearing wear). The owner purchased the vehicle used and was never notified by Hyundai of service campaign 966. The owner also was never notified of NHTSA recall 20v543000 (abs module fire risk), which remains open and unrepaired on this vehicle, demonstrating a pattern of failed manufacturer notification to the current registered owner. This vehicle is a class vehicle in the Hyundai/kia theta ii engine class action settlement (in Hyundai and kia engine litigation), which extended powertrain coverage to a lifetime warranty for connecting rod bearing failure on 2018 Tucson vehicles equipped with the theta ii 2. 0l engine. The failure mode experienced is precisely the defect this settlement and campaign 966 were designed to address. Component that failed: engine, specifically connecting rod bearing/short block assembly. Component is available for inspection. Vehicle has approximately 71,000 miles. The failure created an immediate and severe risk of fatal collision involving a child passenger. Manufacturer has been contacted and has denied warranty coverage. Nhtsa action is requested regarding both the engine defect denial pattern and the unrepaired abs fire-ri.
My 2021 Hyundai Tucson has experienced repeated engine-related failures associated with a knock sensor (p1326) fault that causes the vehicle to enter limp mode and lose power while driving. This issue has occurred multiple times at approximately 15,000, 17,000, 41,000, and 90,000 miles and has resulted in four separate incidents requiring towing. During these events, the vehicle suddenly loses power and cannot maintain normal driving speed, creating a hazardous condition while in traffic. The vehicle has undergone multiple repair attempts, including an ecm update and three knock sensor replacements. Despite these repairs, the issue continues to recur and no root cause has been identified. Hyundai has not provided a permanent fix and has advised continued operation of the vehicle unless the issue occurs again. This ongoing condition presents a safety concern due to the risk of sudden loss of power while driving.
I bought this car 6 months ago. I did not know it had a recall on the engine. The engine just died a week ago. I brought it to Hyundai and the confirmed it was a recall and go ahold of corporate. Corporate is refusing to fix the recall because they said "I should have brought it in at the original recall in 2020. " I did not own the car there and I was not aware of the recall at all. [xxx] is my husband he is the other owner of the car. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).
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.

While driving my vehicle, the engine rpm suddenly revved very high, and the vehicle hesitated to accelerate. A warning messaged appeared stating "transmission too hot stop safely. " I was driving up a hill when this happened. I pulled over and turned the vehicle off for about two minutes. When I restarted the vehicle, the warning message disappeared even though the vehicle would not realistically have cooled down that quickly. The issue concerns me because it could create a dangerous situation in traffic if the vehicle loses power or hesitates to accelerate when pulling into traffic or climbing a hill. The problem has occurred without warning and does not leave and persistent warning lights afterwards. I am very scared to drive this car, especially when I have my child with me. If I need to move out of the way and someone is driving that is not paying attention, there will be an accident because of the hesitation and the non-movement when I accelerate. I am reporting this issue in case it is related to a defect with the transmission system in this vehicle.
While driving at highway speed, the engine suffered a sudden connecting rod bearing failure (cylinder 3) with no prior warning lamps, messages, or symptoms. The vehicle made a slapping noise, a belt came off, the engine died, and would not restart. The vehicle was towed to an authorized Hyundai dealership. The driver, a [xxx] [xxx] , was able to safely guide the vehicle to a stop without injury. The dealership inspected the engine and confirmed a complete cylinder 3 connecting rod bearing failure. The technician contacted Hyundai techline, who confirmed the diagnosis and recommended engine replacement. The estimated repair cost is $6,500. The failed engine is available for inspection at the dealership. This vehicle is a 2019 Tucson with the nu 2. 0l gdi engine, which is covered under the e2 class action settlement for connecting rod bearing defects. Hyundai service campaign 966 provides a ksds software update designed to detect abnormal bearing noise before catastrophic failure occurs. This update was never performed on the vehicle. The 2019 Tucson was not added to campaign 966 until April 2022, after the vehicle had already been purchased used. The owner was never effectively notified of the campaign and the vehicle was never at a Hyundai dealership where the update could have been performed. Hyundai denied warranty coverage solely because campaign 966 was not completed, despite confirming the failure is the exact defect type the campaign and settlement were designed to address. The vehicle had only 49,437 miles at the time of failure. The engine failed without any prior warning — the exact scenario campaign 966 was designed to prevent. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).
While driving on the freeway, my 2021 Hyundai Tucson se (72,021 miles) suddenly and without warning lost power and entered limp mode. I was able to safely maneuver to the shoulder and exit the freeway. The check engine light came on and is currently flashing. I took the vehicle to autozone where code p1326 was retrieved. I then took it to pep boys for a full diagnostic where p1326 was the only code present. The pep boys report states the vehicle requires immediate attention. The vehicle remains in limp mode and the check engine light is flashing. The vehicle is not being driven as it cannot safely reach freeway speeds. I contacted Hyundai customer care and was assigned case # xxx. I also contacted a Hyundai dealership who attempted to charge a $225 diagnostic fee despite p1326 being a known Hyundai defect covered under recall/service campaign. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).
The contact owns a 2022 Hyundai Tucson. The contact stated that while stopped, the vehicle hesitated to respond, with the check engine warning light illuminated. The contact stated that while the vehicle was parked, it was shaking unexpectedly with a misfire coming from the engine, and the check engine warning light illuminated. The vehicle was taken to the dealer, where it was diagnosed and determined that the fuel injector had failed and needed to be replaced. The vehicle was repaired. The contact later stated that while driving at an undisclosed speed, the vehicle lost motive power, with the check engine warning light illuminated. The vehicle was taken back to the dealer, where it was diagnosed and determined that the cylinders had failed and needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 69,000.
On March 10, 2026, my 2017 Hyundai Tucson entered 'limp home mode' while driving, a known safety defect that causes a sudden loss of engine power. Diagnostic testing confirmed error code p1326 (knock sensor detection system - ksds). Despite this vehicle being covered under the theta ii engine class action settlement (recall 209), which provides a 15-year/150,000-mile extended warranty for this specific issue, the dealership (jim ellis Hyundai of atlanta) is refusing to perform the warrantied repair. Instead, the dealership has provided an estimate (#xxx) attempting to charge me $816. 22 for the knock sensor replacement. They are also withholding the full gds diagnostic scan reports and freeze frame data despite multiple written requests. Furthermore, the dealership is threatening to charge daily storage fees while actively denying a mandated safety repair. This refusal to honor the settlement warranty leaves the vehicle in an unsafe, unrepaired condition. This vehicle is a subject of the in Hyundai and kia engine litigation ii settlement. The refusal of the dealership to perform the ksds-related repair (p1326}) is a direct violation of the court-approved settlement terms and a failure to address a documented safety defect. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).
Bought the 2022 Hyundai Tucson. It was driving perfect no issues then I hit 52,000 miles and the check engine light illuminated. The vehicle started sputtering and idling hard like it wasn’t getting fuel when the gas was pressed. I was on the interstate and the vehicle wouldn’t go over 35mph. Now the check engine light illuminates off and on when it feels like it.
The vehicle has a difficult time turning over when cranking, the rpms are sticking and the car periodically shuts off at red lights. Several warning lights pop up when it won't crank and then other warnings when the car just completely shuts off at red lights. I drive the interstate in [xxx] daily for work, so with the engine stalling my safety is at risk every time I drive it. Likewise when it won't crank, my safety is at risk. I had two Hyundai recalls updated in my car in 2022, Hyundai recall 209 which was a connecting rod bearing test and my car passed so they installed the other Hyundai recall 966 which was software update for the knock sensor detection system to alert the driver of future issues. Those issues are now current. The software is detecting a critical failure which is why the car is shutting off - entering limp mode, or the engine is failing. On April 9th through the 11th, 2026 my vehicle was inspected by a Hyundai dealership, where a technician identified a developing engine concern and advised me to continue driving the vehicle. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).
This vehicle has a considerate amount of oil dilution problems. I have had this vehicle taken in for service several times due to gasoline mixed into the engine oil. Again on March 6 2026 for the 4th time now the vehicle has a check engine light extreme hesitation with an almost stopping jerking motion due to dilution problems. Multiple dealerships claim there is nothing wrong with the car. . There is a distinct gasoline smell in the engine oil. The vehicle at times is almost unsafe to drive due to the hesitation and halting it does on its own. Every time a dealership is contacted my problem is dismissed. There is a burning smell due to the oil gas dilution issue. The car reaches higher temperatures than it should. And now the Hyundai dealership is making me wait almost a month again to have the problem looked at again which then puts me as the driver in an unsafe situation to drive a vehicle with such hesitation and fire risk. If they dismiss this oil and gas mix again and do not repair the car it could seize my engine or maybe possibly even cause fire damage.
This car has major oil consumption that affects the engine and catalytic converter. This can cause engine damage and stalls in driving that affect safety on the roads because the car doesn't accelerate properly. There were no warning signals to indicate this being a problem with the car, especially at purchase. This car will get an oil change and in less than a week, the oil is gone and bone dry.
This complaint involves a catastrophic engine failure in a 2018 Hyundai Tucson that appears to be part of a broader pattern of similar failures reported by other owners. Prior to failure, the vehicle exhibited excessive oil consumption and progressive engine performance issues. These symptoms have been widely reported by other consumers with the same vehicle, suggesting a systemic defect rather than an isolated incident. The engine failed completely while the vehicle was being driven to a mechanic for evaluation. The vehicle experienced sudden loss of power and shut down in the middle of an active intersection, creating a significant safety hazard and risk of collision or fatality. Online consumer reports, forums, and complaints indicate that many 2018 Hyundai Tucson vehicles experience similar symptoms—specifically excessive oil consumption followed by engine failure. Despite this apparent pattern, no comprehensive recall or sufficient consumer warning has been issued. The manufacturer has refused to provide assistance, citing warranty limitations, which raises concerns that known defects are not being addressed and unsafe vehicles remain in operation. This issue presents a serious safety risk due to sudden and unexpected loss of engine power while driving. I am requesting that NHTSA evaluate this as a potential widespread defect and initiate a formal investigation that could lead to a recall to protect consumers.
While driving at approximately 70 mph on a highway under normal conditions, the vehicle experienced a sudden loss of engine power. A check engine light illuminated at the time of the failure, and the vehicle was unable to maintain normal acceleration or consistent speed. The loss of power created a hazardous situation in active traffic, as the vehicle could not safely maintain speed with surrounding vehicles. The vehicle was later inspected by an authorized dealership, which confirmed severe internal engine damage, including cylinder damage and engine misfire requiring major repair or replacement. No clear root cause has been provided. There were no prior warning signs or symptoms before the incident. Warning signs prior to failure: none observed. The vehicle is available for inspection upon request. Dealer confirmation: yes. Manufacturer inspection: unknown.
