general problems of the 2019 Hyundai Tucson - part 1

The vehicle will not get to highway speed causing it to impede traffic and presenting a safety risk for collision.

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.

The contact owns a 2019 Hyundai Tucson. The contact stated while driving at an undisclosed speed, the contact noticed an abnormal sound and the engine seized. The check engine warning light illuminated. The contact stated that while attempting to start the vehicle, the vehicle started. The failure reoccurred. The contact stated while attempting to start the vehicle, the vehicle started and the engine spuddered. The vehicle was towed to an independent mechanic where it was diagnosed with a failed engine. The contact was informed that the engine needed to be replaced. The vehicle was not repaired. The contact was advised to take the vehicle to the dealer. The vehicle was towed to the dealer where it was diagnosed with a failed engine. The contact was informed that the engine needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure and a case was filed. The contact was advised to take the vehicle to the dealer for diagnostic testing. The contact was later informed that the repair was not covered under the recall because of open recalls associated with the contact's VIN. The failure mileage was approximately 81,000.

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.

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.

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.

The contact owns a 2019 Hyundai Tucson. The contact stated that while driving at an undisclosed speed, the vehicle unexpectedly stalled and was idling roughly. The message “stop driving” was displayed. The contact stated that the vehicle failed to accelerate and lost automotive power. The failure had occurred several times. On one occasion, the vehicle had to be towed. The vehicle was able to restart after several failures. The vehicle was taken to the dealer, where it was diagnosed with engine failure due to excessive oil consumption. The contact was informed that the engine needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 59,000.

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.

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).

The vehicle has had two catalytic converters replaced in 70,000 miles.

Oil extremely hot and burnt to oil stick. Running really hot. Dangerous possible fire hazard.

Low oil, burnt oil on dip stick, engine running dangerous hot, lights on on dash, engine knocking.

The vehicle has consumed the oil and no light came on. I drove and I checked when the running engine start doing a dry noise and loose the power. The stick was completely dry, I filled with 2 litters and now the stick show in the half. My vehicle has 60k miles and tomorrow will check on the servis. It is unacceptable first how the vehicle consumed the oil and the second the system didn't notify risking an overheat and posing an elevated risk to spop in the middle of the road causing an accident or starting a fire due to overheat.

Limp mode, knocking , engine light. Only has 62,768 miles on it. I can't fill out campaign 966 or 982 on the official web site for extended coverage.

Purchased this car used 3 years ago. Followed owner's manual for oil and filter changes. On 1/2/26 the engine seized, had it towed to Hyundai dealership and they will not approve a replacement for the engine because they said I hadn't followed maintenance guidelines. I submitted all receipts and they still are denying. I had the ksds and all Hyundai campaigns addressed which was to extend the warranty and they still deny. No warning lights whatsoever came on until the engine seized on the parkway. Hyundai knows there is an issue with these engines but still won't step up.

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 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.

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.

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.

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.

High oil consumption, taken to dealer for oil consumption test, have to drive vehicle 1000 miles , then take vehicle back to dealership to see how many quotes of all I’ve burnt or lost recheck oil levels.

Beatriz duran scarlett. B. Duran@gmail. Com 734-360-5857 313-917-0531 vehicle information: • VIN: km8j23a40ku841552 • 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.

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.

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.

Oil consumption.

Car is burning oil quickly. Had 2 oil changes within 3 months. Way before it was needed. No oil leaks detected. Oil gets dark fast and is burning off quickly. Take to pep boyz and other repair shops. Not yet taken to dealership.

My engine has an oil consumption problem that I've been dealing with Hyundai on. The vehicle is a 2019 Hyundai Tucson. Last Friday [xxx] my car lost power on the freeway on a bridge and I began to slow down and couldn't pull over due to no shoulder. I had myself and my family in the car with me, (wife, [xxx] , [xxx] ) my car has failed two oil consumption tests and had a combustion chamber cleaning to try to resolve this issue. Now after losing power, the dealer has gone back on their word of engine replacement because Hyundai denied the claim. They are telling me the oil consumption lead to the catalytic converter getting plugged and losing power. The engine light for that has been on throughout all of the oil consumption testing (months) information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

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.

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.

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.

The contact owns a 2019 Hyundai Tucson. The contact stated that while at a red light, the missing key warning light illuminated. The check engine warning light illuminated. The hazard lights were independently deactivated. The contact became aware of an abnormal odor and smoke on the interior of the vehicle and the exterior of the vehicle. The contact stated that all the door latches were independently locked, and the engine seized. The contact stated that her minor child was also an occupant of the vehicle at the time of the failure. The contact stated that a nearby police officer and other bystanders assisted with removing the contact and the minor child from the vehicle. The contact stated that it was a very traumatic experience, and the contact was very fearful for the lives of her minor child and herself. The contact had a doctor's appointment scheduled; however, because of the failure, the appointment had to be rescheduled. The vehicle was towed to the dealer; however, the vehicle was not diagnosed. The contact was offered a trade-in option. The contact declined the trade-in option. The manufacturer was not made aware of the failure. The failure mileage was approximately 52,000.

The contact owns a 2019 Hyundai Tucson. The contact stated that while driving on a main road at 20 mph the vehicle experienced a reduction in automotive power until the vehicle came to a complete stop, the contact was able to pull over onto the side of the road, and the check engine light would illuminate intermittently. The vehicle was towed to a local dealer where the vehicle was not diagnosed as the contact was advised that their VIN was not included in any open recalls. The vehicle was not repaired. The manufacturer was notified of the failure. The approximate failure mileage was 132,000.

P012800 failure on thermostat for engine.

Engine making knocking sounds, losing power, no indication of low oil levels until very low.
