Engine And Engine Cooling Problems of Hyundai Tucson - part 2

I am the original owner of this car and in June 2025 I brought my car to Hyundai from noises and they told me it had no oil despite me being up to date with oil changes on the vehicle. They told me they were going to do an oil consumption test and once they did that the engine was denied. 6 months later 3 days after an oil change and no check engine light on, the engine fails while I’m on the side of the highway. This car is not safe. Check engine light was not on and I am always up to date with my cars maintenance.

Hello, my 2019 Hyundai tuscan I have owned for 3 years-4 years. Unfortunately it is a gdi motor, it uses oil so bad, even though I do change the oil every 3,000 miles, and do every maintenance on the vehicle that is told to me done, ever time I change the oil it is low, even though I top it off through out the 3,000 miles. I have no leaks at all and it is just evaporating, I do not think this is right for a 2019… there is several issues and concerns from other buyers with this issue. There should be a fix to this, ASAP.

Oil light comes on between changes at about 1500 miles before needing one, oil does not show on dipstick and have to repeatedly put on in engine. Chance of engine seizing or jumping time.

Am submitting a safety complaint regarding my Hyundai vehicle due to repeated engine power loss (limp mode), excessive oil loss, and a denied engine recall replacement. I initially brought my vehicle to the dealership after experiencing engine power loss/limp mode, engine oil loss, and illuminated check engine warning lights. The dealership confirmed that my vehicle was covered under an engine recall and stated that the recall procedure was completed. As part of this process, the dealership performed an engine combustion-related service and charged me approximately $1,600. After this repair, I drove the vehicle for approximately 1,000 miles. When I returned the vehicle to the dealership, the vehicle entered limp mode on the same day it was brought in, and the check engine light was illuminated again. The dealership advised me that the vehicle had lost an excessive amount of engine oil during the 1,000-mile period. Due to the continued engine issues and oil loss, the dealership requested a full engine replacement under the recall. However, Hyundai denied the engine recall replacement request. The vehicle’s repeated loss of power, excessive oil consumption, and limp mode create a serious safety concern, especially while driving at normal road speeds. I am concerned that the recall remedy was ineffective and that the denial of an engine replacement places drivers at risk. I am requesting that NHTSA review this matter for potential safety defects and improper handling of a known engine recall issue.

Car engine seized and lost all power going 60mph down the highway at night with my child in the back seat. I have poured quarts and quarts of oil in this vehicle because it burns oil at an alarming rate until it eventually runs dry and the engine seizes. This is extremely dangerous and luckily my child and I were able to drift to the side of the road without harm and injury. Very discouraging that there are thousands of these cars and engines on the road that can literally seize up at any minute. Maintenance was performed and kept up with. The oil pressure light had been flashing when the vehicle turned but was flashing even when oil had just been changed. These engines are dangerous and have people in a financial hard spot. I still owe $16k on a car I can no longer drive and that Hyundai is saying due to owner maintenance will not get an engine replacement. The facebook group Hyundai oil consumption test has thousands of people dealing with the same exact issue on these cars and engines.

Oil component failure causing extreme heating within the engine and catalytic converter which poses risk for engine fire. This oil consumption issue was addressed by the dealership who ran a test to see how much oil was consumed. The test results showed that the vehicle was burning oil at a high rate and would ultimately result in engine failure. The low-oil light has never come on indicating a need for an oil change. Despite this, I have constantly pulled my own dip stick and got changes every 2,000 miles. For this make and model, they required a change every 5,000 miles. When I notified Hyundai corporate over this concern. They claimed due to it being outside of warranty, that it does not matter what my engine light has been doing since I got the car, nor the issue with the oil consumption, they refuse to address any of these problems as being a manufacturing problem. The maintenence has been kept up since I got the car, so the manufacturer is not acknowledging the constant issue with Hyundai tuscon engine dangers. If a fire were to occurr, I was told this is not Hyundai's responsibility due to me not being the first owner and it not falling within warranty. After the combustion test, Hyundai claimed that they refilled my oil. When I checked my dip stick after only driving 100 miles, the image attached will show the resulting levels. My oil light is still not coming on despite this. Even when it has been much lower than the pictured level. This, paired with the super heated catalytic converter due to the oil consumption, is going to cause an engine fire and is not fair to the consumer.

While operating the vehicle, the engine shut down. Complete loss of power. Engine would restart, stall and then not restart. Vehicle immobile. Vehicle towed to dealership since could not be driven. Strong smell of gasoline.

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 contact owned a 2022 Hyundai Tucson. The contact stated that while the vehicle was parked, the contact's neighbor knocked on the contact's residential door and informed the contact that the contact's vehicle was on fire. The contact stated that when she went outside, the contact noticed that the entire front of the vehicle was on fire. The fire department was called, and the fire department extinguished the fire. A fire report was filed. The contact stated that the vehicle was burned all the way to the rear seat of the vehicle. The fire burned another vehicle that was parked in the contractor's yard. In addition, the contact stated that the fire burned a good portion of the contact's residential yard. The vehicle was towed to a local tow yard. The vehicle was condemned a total loss by the insurance company. The fire inspector informed the contact that the fire started in the engine near the battery. The manufacturer was not made aware of the failure. The failure mileage was approximately 76,500.

Oil consumption, will change oil and within weeks I will be down 23 quarts of oil.

Severe oil consumption. The vehicle eats the oil at an alarming rate. Having to fill the oil tank very often and the engine light has been on. It is affecting acceleration at 30mph where the engine warning light will flash. It also completely dies while driving. Very unsafe and needs to be resolved.

Vehicle is showing ksds-related engine warning behavior and the Hyundai dealership performed a diagnostic scan. The service manager told me, “I don’t recommend you driving it,” due to a potential engine safety issue. However, Hyundai motor America’s national consumer affairs team is refusing to authorize towing or a loaner/rental until after a full diagnosis is completed. The dealership cannot complete the diagnosis unless the vehicle stays on-site, but I am unable to safely leave it because Hyundai is refusing transportation assistance and I was told not to drive it. This forces me to drive a vehicle they identified as unsafe in order to complete the required inspection. This involves ksds/engine failure risk, which has been associated with stalling, loss of power, and possible fire hazards. Being advised not to drive while being denied towing or transportation creates a serious safety concern for myself and my children. I am requesting NHTSA document this incident because Hyundai is creating a safety hazard by refusing support for a vehicle they identified as unsafe to operate.

The engine on this vehicle burns oil quickly which is a known defect. I took the vehicle to the dealership and both times I was told everything was working fine. On 12/5/2025 the vehicle just lost power while driving. After getting the vehicle towed to a mechanic they said I needed a new engine.

I’m submitting this complaint to report what appears to be a serious safety-related engine issue in my 2017 Hyundai Tucson sport 2wd with the 1. 6l di turbo engine [t-gdi gamma]. I’m aware of NHTSA recall 21v-727, which covers 2017 Hyundai Tucson models with the 2. 0l engine for premature engine bearing wear. The symptoms covered by that recall are nearly identical to the symptoms my vehicle is now showing. My VIN shows no open recalls or service campaigns on Hyundai’s website, but the problems I’m experiencing match those found in many other consumer reports for this same year, make, and model. My vehicle has only 80,000 miles and has had regular maintenance. Examples include loud knocking from the engine that rises and falls with rpm, and metal shavings in the oil. One complaint that reflects the same pattern can be found in NHTSA id 11680114, which describes engine knocking and metal debris with no warning lights or alerts. My vehicle has also shown no warning indicators. These issues pose a safety risk because they can lead to sudden engine failure while driving. Based on the volume of similar complaints and the overlap with the existing recall, I’m concerned that the defect may affect more than the engines currently covered under 21v-727. I’m requesting that NHTSA review this matter and determine whether Hyundai should extend or expand the recall to include vehicles equipped with the 2017 Hyundai Tucson sport 2wd 1. 6l di turbo dohc 4cyl. Please investigate this issue and hold Hyundai accountable if these defects extend beyond the vehicles already listed.

On [xxx], my 2025 Hyundai Tucson hybrid displayed a red dashboard alert instructing me to “stop vehicle and check brake system. ” the vehicle experienced brake system warnings and a loss of power steering, requiring me to pull over. I immediately contacted Hyundai through the bluelink system, and the bluelink operator confirmed that multiple fault codes were visible in Hyundai’s system. I scheduled a Hyundai service appointment at the next available date. On [xxx], before the scheduled service appointment could occur, the vehicle experienced a sudden and total electrical failure while traveling at highway speed (approximately 65 mph). The vehicle lost propulsion and displayed brake system warnings. After reaching the shoulder, the vehicle also lost hazard lights while disabled in heavy rain. The vehicle was towed via Hyundai bluelink to a Hyundai dealership and removed from service. The occupants at the time of the incident included my wife and my minor child. The loss of propulsion, braking warnings, power steering, and hazard lights created a serious risk of a rear-end collision and injury. Due to repeated and escalating safety-related failures involving electrical, braking, and steering systems, I no longer consider the vehicle safe to operate.

My motor has a knocking/tapping noise that is obnoxiously loud. My oil level is always changed on time every 3k miles. I have 146,257 miles on my vehicle. I was informed from my mechanic shop that many of the 1. 6l motors have issues. I have never had an engine noise then boom its knocking. I was informed not to drive my car to further damage the vehicle. I do not drive it but now am stuck in a loan for a vehicle I cannot drive. I had zero warning for this matter.

Car died/lost power while driving in traffic 11/28/25. Good samaritan was kind enough to push me off the road out of traffic. Car was towed to Hyundai dealer that day, then 12/1 told engine failure, required engine replacement. Class action lawsuit settlement for engine replacement, but denied by Hyundai because of "neglect", since I am not able to locate all of the service records that they request. Known faulty rotating assembly, and Hyundai has implemented concerted practice of denying warranty coverage for failed engine. Now having to pay almost $8k to replace with new engine, but concern that new engine will have same issue. (multiple posts about this). There was high potential for significant traffic collision, injury due to sudden, catastrophic engine failure. Traumatic experience.

My 2019 Hyundai Tucson previously required an engine replacement due to a known defect. After the engine replacement, the check engine light remained on. Recently, the check engine light began flashing, and the vehicle was towed to the dealership. I was informed the vehicle has a radiator/cooling system failure. Given the history of engine defects and warning lights, I am concerned about vehicle safety and reliability.

The contact owned a 2021 Hyundai Tucson. The contact stated that immediately after purchasing the certified vehicle, the vehicle went into limp mode while her grandson was driving approximately 65 mph, and the vehicle decelerated to 7 mph. The vehicle was towed to the local dealer who diagnosed that the nox sensor had failed and needed to be replaced. The vehicle was repaired but while leaving the dealer, the failure reoccurred. The vehicle was towed back to the dealer who replaced a second nox sensor and the catalytic converter. The contact stated that days after retrieving the vehicle, the failure reoccurred, and the vehicle was towed back to the dealer who diagnosed that the nox sensor had failed for a third time, within several days of owning the vehicle. The vehicle was traded in. The manufacturer was notified of the failure. The failure mileage was 28,944.

My 2019 Hyundai Tucson, VIN [xxx] , has developed engine knocking, which may indicate internal engine failure. A mechanic has suggested a possible loss of cylinder compression, though the exact cause has not been confirmed. Hyundai vehicles from similar model years have experienced engine failures related to bearing wear and metal debris, leading to stalling, loss of power, and complete engine failure. These failures present a serious safety risk, particularly if the engine fails while driving. I am concerned that this defect could result in sudden loss of power or engine seizure, increasing the risk of an accident. I am submitting this complaint to ensure the issue is properly investigated and addressed. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

The engine has begun making a persistent knocking sound, especially during acceleration. A mechanic inspected it and indicated it may be related to cylinder compression issues or internal engine damage, but the exact cause is not yet confirmed. Because this matches symptoms associated with the known connecting rod bearing defect affecting the 2. 0l nu gdi engines, I am requesting a full warranty inspection under the engine ii settlement and Hyundai’s extended engine warranty program.

2020 Hyundai Tucson engine blown @ 89,307 miles and 1,265 miles after oil change due to missing oil plug. Daughter drives about 5 miles per day for college and groceries. The day before thanksgiving 2025, her 2020 Hyundai Tucson died about 48 miles down the highway without warning, no prior warning lights or sounds before shutting down. I had the car towed to the local Hyundai dealer in the town where her college is, where they told us the engine was totaled due to a lack of oil and a missing oil plug. I discussed with the Hyundai service advisor about having an extended warranty; however, they would not work with me or the company I had the extended warranty with, mentioning they would not cover the engine failure due to the oil plug being missing. I asked the service advisor in a separate conversation whether an oil pan drain plug that was not properly torqued during an oil change could remain in place for some time—particularly during short, low-speed driving—and then gradually work loose over additional miles. The service advisor mentioned that in situations like my daughter’s, where only about 1,265 miles were driven after the oil change (mostly short trips), it would be within reason for an improperly installed drain plug to stay in place until a longer highway drive with higher rpms, at which point it could back out completely and result in a sudden oil loss and engine shutdown. The service advisor also mentioned that this is something they had seen before and is not unheard of on these vehicles.

The car began making a knocking sound on my 5. 8 mile drive. On my drive home from work, the knocking was louder, and the car barely accelerated on the highway and over-revved trying to hit at least 50 mph to keep up with the flow of traffic. I took the car to the Hyundai service center immediately using city streets rather than the highway. I had a family member follow me to make sure I made it to the service center as well as give me a ride home after I dropped off the vehicle. As I was driving there, the car had a hard time accelerating from a stop and barely maintaining speed of the flow of traffic and the “check engine” light came on and flashed as I got closer to the dealer service center. The dealer service center confirmed that the engine needs to be replaced due to the connecting rod bearing failure, a common issue with the 2. 0l i4 f dohc 16 v engine in my 2018 Hyundai Tucson. The Hyundai service manager has repeatedly confirmed that the engine issues presented in my car are consistent with a recall for the same model engine found in my car.

I am writing regarding a serious incident involving negligent automotive service performed by jiffy lube store #687. On October 24, 2025, I took my 2017 Hyundai Tucson to this location for a standard oil change. I trusted that the service would be completed properly and safely. However, on November 21, my vehicle’s oil lamp unexpectedly illuminated. Concerned, I returned to jiffy lube on November 22, where employees informed me that they had “sealed the small leak and topped [my] oil,” adding that I was entitled to two top-offs between oil changes and “should be good for two weeks. ” tragically, the very next day, November 23, the oil lamp flashed again. My vehicle then shut off while I was driving, with my children in the back seat. This was a frightening and dangerous situation for all of us. I am now left confused, stressed, and unsure of the full extent of the damage.

Engine rpms surged and the car accelerated forward without foot on the gas pedal concerned about possible pedestrian accident or collision with objects and prop. Damage. Dealer was unable to duplicate the problem and no repair was made there is no warning. . . I never know when it will happen and it has occurred in a number of different circumstances.

While driving under normal conditions, my engine experienced a sudden and catastrophic failure. The check-engine light illuminated, the vehicle began shaking violently, and I was forced to pull over immediately due to safety concerns. There was no prior warning and no oil pressure or oil warning light activated at any time before or during the failure. After stopping safely, I checked the oil level and found it lower than expected. I added oil as a precaution, but the condition did not improve and the vehicle became inoperable and required towing. The engine assembly remains intact and available for inspection upon request. This failure posed a serious safety risk, as the loss of engine function occurred without warning while the vehicle was in motion, creating the risk of stalling or loss of control. The vehicle was inspected by an authorized Hyundai dealership. Hyundai motor America denied warranty and goodwill assistance, citing mileage and alleged insufficient maintenance documentation, despite the vehicle being within the 10-year powertrain period and despite the nature of the failure. Routine maintenance was performed throughout ownership; however, some historical service records are unavailable due to the age of the vehicle and changes in service locations over time. Multiple facilities no longer retain records from that period. Notably, no oil warning indicators never activated, which raises concern regarding the failure mechanism. Hyundai has acknowledged widespread engine issues in this engine family involving oil consumption, bearing failure, and sudden engine seizure. The symptoms and progression of this failure closely align with those known defect patterns. This complaint is submitted to document a sudden engine failure presenting a clear safety concern and to assist in identifying potential defect trends. This car has undergone previous engine repair, ac condenser and entire turbo by their service department previously 2022 & 2024 respectively.

The contact owns a 2014 Hyundai Tucson. While the contact's wife was driving at an undisclosed speed, several unknown warning lights illuminated, and the vehicle lost motive power. The contact's wife was able to coast the vehicle to the shoulder of the roadway. The vehicle was towed to an independent mechanic, where it was diagnosed with engine failure. The contact was informed that the engine needed to be replaced. The vehicle was not repaired. The contact was advised to have the vehicle towed to the dealer. In addition, the contact was informed of campaign 953 (extended warranty on the engine). The vehicle was later towed to the dealer, where it was diagnosed with engine failure. The contact was informed that the engine needed to be replaced. The vehicle was not repaired. In addition, the contact was informed of campaign 953 (extended warranty on the engine). The manufacturer was made aware of the failure by the dealer. The manufacturer initially agreed to a good-faith repair. The manufacturer declined the good-faith repair because the campaign 953 requirement was not performed. The contact had not received information on campaign 953. The failure mileage was approximately 130,000.

The contact's wife owns a 2022 Hyundai Tucson. The contact stated that his wife reported that the vehicle shuddered significantly and failed to exceed 30 mph while driving. The check engine warning light was illuminated. The vehicle was taken to the dealer, where it was diagnosed that the fuel injectors were leaking, and the dealer determined that the fuel injectors needed to be replaced. The dealer informed the contact that the manufacturer had redesigned the fuel injectors due to the known failure. The dealer informed the contact that the repair could not be covered under the extended warranty because the vehicle had exceeded the required mileage. The contact was informed that parts needed to be ordered to repair the vehicle. The vehicle had not yet been repaired. The contact related the failure to TSB number: 22-FL-002h. The manufacturer was notified of the failure, and a case was filed; however, no assistance had been provided. The failure mileage was approximately 65,000.

The engine and engine management system of my 2018 Hyundai Tucson experienced repeated failures resulting in loss of propulsion and unsafe drivability. In November 2025, while traveling approximately 75 mph on a freeway, the vehicle suddenly entered limp mode without any prior warning, causing an abrupt loss of power in active highway traffic. No warning lamps or messages appeared before the failure. After the loss of propulsion occurred, the check engine light, battery light, and oil light illuminated sequentially. Diagnostic trouble codes p1326 and p0326 were recorded. Initial inspection indicated severe oil consumption despite a recent oil change less than 2,000 miles earlier. A Hyundai dealership replaced knock sensors under warranty. Shortly after release (30 miles), the vehicle again exhibited severe drivability issues, including a flashing check engine light, and required immediate towing. A second Hyundai dealership replaced the short engine block under warranty. Approximately 180 miles after the engine replacement, the vehicle again developed unsafe drivability symptoms, including delayed throttle response, failure to accelerate unless the accelerator was fully depressed multiple times, jerking or lugging when slowing or stopped, and a faint whining noise. The check engine light illuminated again. These failures represent repeated loss of propulsion and unsafe operation following manufacturer-approved repairs, including full engine replacement. The vehicle has been out of service for approximately 57 days and remains in the custody of a Hyundai dealership awaiting diagnostics. The vehicle is available for inspection upon request. The sudden and unpredictable loss of power at highway speed created a significant risk of collision and serious injury to the driver and surrounding motorists.

I recently purchased vehicle and when checking recalls from my local Hyundai dealership I was advised that there was two previous attempts to have engine replaced due to knocking and it was denied this recalls is the 209 I escalated to Hyundai corporate and after taking to a Hyundai dealership and paying for a diagnostic test they advised car doesn't have oil pressure and the oil pump needed replaced and Hyundai corporate denied repairs saying this didn't pertain to recall 209 because my engine is a 1. 6 liter and it was ok only to the 2. 0 engines, I would like to report this and ask for help please.

I know there is a re-call for my vehicles engine and year with model. I am having serious issues with my vehicle related to the recalls for the same year and model. I feel unsafe driving my vehicle and now I do not know what to do.

My car on the expressway wouldn't go over 40 and this was happening intermittently so my car was unsafe. No check engine light but it was just at the dealership for an oil change. Has. Been an ongoing problem since I bought the car! smells, gets hot!.

Oil consumption problem caused vehicle to go into limp mode on freeway. Manufacturer states 1qt loss every 1000 miles is acceptable.

My adult son was driving and under the hood started to smoke. He pulled over and opened the hood to take a look and then a fire started under the hood! the fire department was called and they put out the fire, cut the gasoline and duct taped it up so the fuel line would not further ignite the hot engine. My insurance is looking into what would have caused a random under the hood fire. Luckily no one was injured. However the engine section of the car is melted beyond belief. My insurance has not told me if the car is repairable or not.

Fitzgerald countryside Hyundai - address is 27419 us hwy 19 n, clearwater, FL 33761 refuses to fix a recall on my unsafe car. Check engine light flashing due to code p1326 which is an issue detected by ksds that monitors unusual engine vibrations and is designed to prevent engine damage.
