2019 Hyundai Tucson

I have noticed that the engine oil level in my vehicle drops significantly between regular oil changes. Despite adhering to the manufacturer's recommended maintenance schedule, I frequently have to add a quart of oil after driving only about [800~1,000 마일] miles.I understand that this is a widely reported issue with Hyundai Owners Forum affecting 2019 models. Many experts and fellow owners have identified that this rapid oil loss is often caused by manufacturing defects, such as faulty piston rings, which can eventually lead to catastrophic engine failure.As a Hyundai owner, I am highly concerned about the safety, reliability, and decreased resale value of my vehicle. Running low on oil without warning creates a high risk of sudden engine breakdown while driving on the highway.I kindly request that Hyundai Corporate or my local authorized dealer investigate and resolve this matter. Specifically, I am asking for:An official engine inspection and a proper Oil Consumption Test.Necessary repairs or a full engine replacement under the applicable powertrain warranty at no cost to me.

The 2019 Tucson has 60,413 miles. My daughter drives it very low mileage - a couple of miles a day back and forth to school. Friday she was driving and the car lost engine power and it stopped driving. No warning lights. There was a cloud of smoke and it smelled like burning plastic. She was on a busy road but pulled over and quickly exited the vehicle. I had it towed and the mechanic says the engine oil was empty and the engine has seized. We do regularly scheduled oil changes. No lights or warnings and the car just stopped in traffic.

While driving, the check engine light began flashing and the vehicle shook severely due to engine misfiring. The vehicle has had a recurring cylinder 3 misfire throughout ownership. Spark plugs and ignition coils were first replaced around 40,000 miles and replaced again in December 2025 for the same recurring issue. A Hyundai dealership inspected the vehicle and found codes P0300 random misfire and P0303 cylinder 3 misfire. The dealership technician documented that the piston rings did not look good and confirmed the catalytic converter was damaged as a result of the misfires. The vehicle has had an engine rattle at idle, oil consumption, and blow-by since early in ownership. The engine defect is progressive and predates the current mileage. The flashing check engine light and severe shaking while driving at highway speeds created an unsafe condition with other vehicles on the road. The problem has been confirmed by a Hyundai dealership. Hyundai Motor America was contacted and denied goodwill warranty assistance. The vehicle is available for inspection upon request.

I purchased this vehicle from CarMax about 5 months ago. It had 74,XXX miles. CarMax showed no open recalls and a printed sheet from your site showing the same. Several weeks ago, while driving, the engine seized. I sent it to one of the local Hyundai dealers for repair. Hyundai said because recall Campaign #966 had not been performed, they would not replace the engine under the extended warranty. When I purchased the vehicle, I had the foresight to purchase an extended warranty from Assurant. Eventually I found they will cover the repair. I have to pay the $600 deductible, plus a $350 labor charge for diagnostic work. Here is my problem, CarMax told me there was no open recalls (based on your web site), and I counted on CarMax having an accurate knowledge about this when I purchased the vehicle. This is particularly disturbing because in 2022 CarMax settled out of court with 30+ states in part, for failure to disclose open recalls on vehicles they sold. True, I could have checked myself, but how did your entity report no open recalls on this VIN, and CarMax reported no open recalls on this VIN, but Hyundai was aware of the open recalls, and denied an engine warranty repair because the recall campaign had not been completed? There are two other open campaigns, # 933 and #P33 as well. The Hyundai dealer is going to perform these recalls after the repair. To summarize, I purchased this vehicle in good faith that the information provided on the NHTSA sheet, and the CarMax sheet were correct there were no open recalls. My bank financed the auto under the premise it was a safe reliable risk for them. Now, I'm going to be out $950 plus rental car expenses I've already paid. Please contact me if you have more questions.

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.

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.

The component involved is the engine and associated knock detection system (KSDS). The system triggered a P1326 code indicating abnormal engine knock associated with a known defect condition. On February 14, 2023, while driving on the freeway, the vehicle suddenly entered reduced power (“limp mode”) and lost acceleration capability in active traffic. This created a safety risk, as the vehicle was unable to maintain speed with surrounding traffic or accelerate as needed for normal driving conditions. There were no sufficient warnings prior to the event to allow safe planning or avoidance of the loss of power condition. The system activation itself (P1326 and limp mode) was the first indication of the severity of the issue. The problem has been reproduced multiple times, with repeated P1326 events occurring after the initial incident. The condition has been inspected and partially confirmed by a Hyundai dealership. In March 2026, dealership records documented that oil contamination was causing catalytic converter failure, indicating ongoing engine-related deterioration consistent with the defect condition identified by the knock detection system. Despite these findings, the underlying engine condition has not been resolved. The KSDS system is designed to detect a potentially serious engine defect and limit engine power to prevent further damage. However, it does not correct the underlying defect. As a result, the vehicle may continue to operate with a known compromised condition that can trigger reduced power unexpectedly. This creates an ongoing safety concern. A vehicle that can suddenly lose acceleration due to a known defect presents a risk to the driver, passengers, and other motorists, particularly during freeway driving, merging, or other situations requiring normal engine performance. The vehicle remains available for inspection upon request.

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.

While driving a flashing engine light came on in my 2019 Hyundai Tucson. This made the car slow down and have no power. I brought the car to the nearest mechanic, they told me it was the knock sensor and told me it was a recall for this car, I should bring it back to the dealership. I called the dealership and they had told me to bring the car in. They inspected the car on 8/30/24 at 44,990 miles and told me it was the knock sensor and replaced it. On 11/4/24 at 46,246 miles the car was brought back in for the same issue and the car was inspected again, it was the knock sensor. This time the software was replaced. On 1/29/25 at 48,042 while driving on a highway going 70 mph the flashing light comes on again, brought it back to the dealership and I was given a loaner. The reached out to me and told me it was the knock sensor. They had the car for about 5 days. On 2/14/25 at 48,248 again, driving on a highway the flashing engine light appears again. Called the dealership and brought in the car and again, the knock sensor. On 12/31/25 at 56,712, driving on the highway, the flashing light appears again...On 1/2/26 the car goes back to the dealership, they call me and said that it's the strangest thing, the serpentine belt is worn, and it was making a banging sound which was setting off the knock sensor. At this point they offered to put in a new serpentine belt. I refused because after 5 failed attempts, I decided to bring it to my mechanic (I had lost all confidence with Hyundai mechanics). He did replace it. At this point I sent a letter to Hyundai motors stating all the facts that have been happening and asked for a buyout. After their investigation they called me and said, because you brought it to your mechanic they couldn't help me, but, if it happens again, bring it back to Hyundai. On 2/2/26, 57,286, again. I called the dealership and brought it back. This time they said that they didn't have a loaner to give so I rented one, 4 days. This is 5 failed attempts

The engine consumes oil and requires catalytic converter replacement every year at inspection. The engine has been maintained with regular oil and filter changes and the oil is continuously needing to be topped off between changes. I have owned the vehicle for 5 years and have replaced the catalytic converter 3 times. The first time I had it replaced it was still under warranty and it was replaced by the dealership. The technician stated that it was a known issue with these vehicles. It was about six months before the check engine light was on again and showing the same code and problem. Every year I am replacing the catalytic converter to pass inspection. I have taken it to different locations every year to try to find a solution to this and they all say the engines are burning too much oil and causing catalytic converter failure.

On three occasions while the vehicle was idling, the dashboard screens and interior lights went completely black, and the steering wheel jerked abruptly in my hands. This sudden electrical failure creates a serious safety concern, particularly if it were to occur while driving at higher speeds. The dealer has not been able to reproduce the problem. There were no warning lamps, messages or other symptoms prior to the failure. There were no warning lamps after the problem occurred. The vehicle has been inspected multiple times by a Hyundai dealership. On one occasion, the dealership retained the vehicle for approximately two months but reported no definitive findings despite error codes being present. On a later visit following another failure, no error codes were recorded. The dealership replaced the head/stereo unit and confirmed no active recalls, yet the issue continues. This problem first occurred while the vehicle was covered under an extended warranty, but due to its intermittent nature, it was not resolved before the warranty mileage threshold was exceeded. I have since found numerous similar complaints online from owners of the same model year describing electrical blackouts and steering-related concerns. A Hyundai service manager advised me to dispose of the vehicle, which further reinforces my concern that the defect may be known but unresolved. I believe this issue represents a potential safety defect and warrants documentation and review. Thank you for your attention to this matter.

I am submitting this complaint regarding excessive and abnormal oil consumption in my 2019 Hyundai Tucson. Despite regular maintenance and oil changes performed according to manufacturer recommendations, my vehicle consumes oil at an excessive rate, requiring frequent oil top-offs between oil change intervals. I have experienced low oil levels with little to no warning, which poses a serious safety concern due to the risk of engine failure while driving. The vehicle does not show visible oil leaks, suggesting internal oil consumption. This issue appears to be consistent with numerous consumer complaints involving Hyundai vehicles of similar model years and engines. The dealerships have been unhelpful and dismissive, often stating that the oil consumption is “within normal limits” or requiring lengthy oil consumption tests without offering a permanent solution. I feel I am being given the runaround rather than receiving a meaningful repair or accountability for what appears to be a known defect. Excessive oil consumption can lead to engine damage, stalling, or sudden engine failure, which is a significant safety hazard for myself, passengers, and other drivers. Hyundai dealerships have failed to adequately address or correct the issue, despite the widespread nature of similar complaints and known engine issues associated with Hyundai vehicles. I am requesting that NHTSA investigate this matter further, as this defect affects vehicle safety and reliability and appears to be part of a broader pattern with Hyundai 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.

On October 11, 2025, I discovered that my 2019 Tucson had no engine oil. I put three quarts of oil in at that time. Fast forward two weeks, October 25, 2025, and the dipstick read dry again, prompting more oil to be required. Unfortunately, I'm passed the 30 day warranty with the dealership I purchased the vehicle from so now this burden has fallen on my shoulders.

[XXX] [XXX] [XXX] [XXX] Vehicle Information: • VIN: [XXX] • Year: 2019 • Make: Hyundai • Model: Tucson • Mileage: 132,303 Problem Description: On Oct 11, 2025, my 2019 Hyundai Tucson entered limp mode on the freeway, losing power suddenly, posing a safety risk. This followed a dealership visit a couple months ago for a recall engine repair (possibly 21V-727). They returned the car with a check engine light, claiming it was a false error needing a reset on my next visit. No reset was done. On Oct 11, the limp mode forced a tow back to the dealership. They now demand $300 for diagnostics and refuse a loaner, claiming it may not be warranty-related. I’ve escalated to Hyundai national team case number : 41621677 with no resolution after four days. This feels like a safety defect tied to the prior recall work. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The vehicle is experiencing excessive oil consumption and increasingly severe engine performance symptoms. The oil level drops rapidly between changes, but the loss is not due to external leaks. The engine burns oil internally, causing residue buildup and damage to other components — specifically the intake manifold and catalytic converter, which the dealer has now recommended replacing. These issues align with the symptoms addressed in Hyundai Campaign 966 (Engine Monitoring / Knock Sensor Detection System), which is intended to detect early bearing wear and related oil consumption defects. However, the dealership refused to perform the required campaign diagnostics (bearing inspection, KSDS verification, and oil-consumption test) without charging a diagnostic fee. Even though the engine has not yet fully failed or entered limp mode, the excessive oil consumption is already causing secondary damage to emissions and intake components. If left unresolved, this can escalate to engine seizure, catalytic converter overheating, or exhaust-related fires due to unburned oil entering the converter. These are clear safety hazards that can result in loss of power, smoke, or fire while driving. Multiple Hyundai owners have reported identical problems — excessive oil loss, residue damage to emission systems, and dealer refusals to perform Campaign 966 inspections. These patterns indicate a systemic engine defect that leads to downstream component failures, not isolated wear. Replacing the manifold or converter does not correct the root cause, as oil consumption continues after replacement and will likely damage new parts. The dealer’s refusal to perform the manufacturer’s required diagnostics and their attempt to charge for unrelated repairs prevent proper defect identification. This is a serious and ongoing safety issue affecting Hyundai Tucson and other models with the same engine family.

Hyunda dealerships are not replacing engine that have been recalled because Hyunda Corporation is refusing to allow the replacements. They are nit picking at reasons to not replace. I believe it because of the number of replacements needed is overwhelming tothe corporate offices and they are picking and choosing on which car get replaced. We have spent thousands of dollars on rentals waiting over months for decisions and there are no loaners available for the customers. I have written numerous letters to corporate has not responded back. The dealership have threaten to get your vehicles removed from there lots if you have been turned down. They have stranded hundreds of customers with vehicles that done run. We need more assistance in rectifying the situation. To know fault of our own we have been punished.

Due to known oil consumption my car stalled due to no oil left in the engine even though there were 2,000 miles left until my oil change. I have since started to go to my local Hyundai dealership to test for oil consumption and have been tested 3 times and Hyundai is saying that there is oil consumption but it is under the threshold they consider actionable. This is very problematic and can cause many issues for myself and others.

Both Headlights suddenly became very dim WHILE I WAS DRIVING. On normal lights there is almost no light beam coming out at all, and on bright lights there is slightly more lighting, but there is also what looks to be a large shadow across the light beams. I’ve had it checked and there are NO bulbs burnt out.

My car has had an oil consumption problem for over a year that Hyundai refuses to acknowledge. I passed the oil consumption test because the oil burns rapidly when I have about 1,000 miles left before my next oil change. They have replaced my exhaust, catalytic converter, spark plugs, and oil release valve over the course of many visits. Every time I have the oil problem, they find something different to “fix” and I have to pay out of pocket. None of these have fixed the actual problem. The hyundai representative I have been in contact with (after they reassigned my case to someone 3 different times - so it’s never the same person that is familiar with my case), told me there is nothing they can do to help me because the dealerships are independently owned. I am now out of warranty, although I originally brought my car there while it was still covered under warranty.

While almost at a complete stop in the process of putting my 2019 Hyundai Tucson in park at my friends home to drop her off, the car involuntarily surged/accelerated forward over a cement curbing and landscaping timber and slide down a small incline into a tree and landscaping boulder! After looking on line concerning the malfunction it seems there are abundant claims from other 2017-2019 Hyundai Tucson owners that have experienced this exact mechanical defect under this frightening description of a surge or acceleration out of the drivers control! It's the craziest, scariest thing ever. We have taken the car in for a recall concerning the check engine light regarding the catalytic converter prior to this incident. The car is well cared for and maintained and has never been in any accident.

Crash

Car has had shaking during acceleration and a noise (rattle/knock/tapping) from the engine for last 18 months. Dealer “could not find any issues” until July 31st 2025 when the engine broke down with a P1326 code (connecting rod bearing failure) and the engine seized. Vehicle is under class action class with extended 150k 15 year warranty on engine for this concern. Had recall performed for the knock sensor detection system as required by class action. Dealership first asked for most recent oil change record (provided) and than informed that Hyundai declined repairs due to full maintenance records not being submitted. Have now submitted full maintenance records to dealer and Hyundai directly since I purchased in 2023 as certified pre owned. All maintenance performed as per factory recommendations In manual. Hyundai still declining repairs without any explanation.

Hyundai Motor America (Hyundai) recalled certain 2019-2021 Tucson vehicles on September 4, 2020. On December 30, 2020, Hyundai expanded the recall population, and added certain 2016-2018 Tucson vehicles. The Anti-lock Brake Hydraulic Electronic Control Unit (HECU) could corrode internally and cause an electrical short, possibly resulting in an engine compartment fire.

Risk: An engine compartment fire can increase the risk of injury or crash.

Remedy: Hyundai will notify owners, and dealers will replace the HECU fuse. For 2019-2021 model years, the Electronic Stability Control (ESC) software will also be updated. Recall repairs will be performed free of charge. Owners are advised to park outside and away from structures as a precaution until the recall repair is complete. The recall began November 2, 2020. Owners may contact Hyundai customer service at 1-855-371-9460. Hyundai's number for this recall is 195.
