2019 HYUNDAI TUCSON Engine Problems

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.

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.

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

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.

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...

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...

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.

I own a 2019 Hyundai Tucson, Since purchase, I noticed a strange engine noise. The dealership [Dealership Name] told me it was not a problem, but the vehicle has consistently consumed about 1 liter of oil per week. Despite multiple service visits, Hyundai has not recognized this as a factory defect and requested $3,500 for testing. I am concerned that the excessive oil consumption could lead to engine overheating, which may increase the risk of an accident.

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

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

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...

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...

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.

Oil consumption

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...

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.

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)

This vehicle was purchased by me in November of 2024. It was a one owner used car. At the time of purchase, the vehicle was inspected by the dealer and the oil was changed. It had only been driven 3000 miles when the check engine light began flashing. I took it in to a dealership and learned that it was burning oil at an excessive rate causing engine wear and damage. I have since learned that the engine will need to be replaced. I also learned that this is a very common and known problem with Hyundai engines.

The vehicle was brought in just after a month of owning it due to it was accelerating slow and driving bad salesmans sent it to Hyundai dealership for diagnosis and it came back that the motor needed to be replaced due to recall vehicle was in repair shop for over 3 months to get a new motor once returned the very next day the check engine light came back on so I brung it back to the Hyundai dealership per Hub City's salesmans instruction to have vehicle diagnosis again. Hyundai advised that the vehicle needed a catalyst converter among other codes detected on vehicle.

Vehicle is consuming oil at a rate of 2 quarts per 1000 miles which could lead to catastrophic engine failure at highway speed causing serious crash and loss of life. This is apparently a common defect with many Hyundia engines that the manufacturer is actively trying to deny warranty claims.

On a busy highway, my car broke down. It was due to the rod bearings, specifically, the Hyundai Theta "extended warranty"/recall issue, or "recall" issue. There is currently a class action lawsuit against Hyundai. I had the car towed to Hallmark Hyundai in Nashville, TN. I, however, live in Louisville, KY and I was making a road trip to Nashville, TN. I was told by the Service Rep in Nashville that they couldn't provide me with a loaner vehicle because I would be driving it, back home, out of state to Louisville, KY. I paid for a rental car out-of-pocket. Hyundai Corporate told me it would take 60 days to get reimbursed. I picked up the car at the beginning of July, 2025, after the engine was replaced by Hallmark Hyundai. I was told by Hallmark Hyundai that a service employee performed a test drive but it was immediately noticeable...

Engine has been burning through oil. Started the Engine oil consumption test at one dealership. That dealership has now closed leaving me to go to another dealership. They want me to start the process over again. I have had two oil changes, failed the second test and was scheduled to bring my car back for the next step in the diagnostic process. Not only do they want me to pay out of pocket again for an oil change but my car is driving worse. It didn't start the other day and it drives horribly. The safety concern I have is that the engine will seize while driving, causing an accident.

P012800 failure on thermostat for engine

The engine seized will on the highway unexpectedly. While driving on the highway the car suddenly started to slow down and would not pick up speed. I was able to get off on the first exit and make it a close to the right hand land as possible before the car stalled. I was stuck on the feeder road and at risk of being hit from behind. I cranked the car and was unable to move. While calling a tow truck and waiting for it to arrive later I tried to crank the car again and was able to drive it to the nearest safe place.

Substantial oil consumption. Refilling oil once a month. Is not covered yet under engine recall. Dealership purchased from in Virginia Beach will not cover repairs.

My vehicle isn’t in the oil consumption recall yet it uses oil very fast then the warning light doesn’t come on till oil is almost all gone ! I’m having to add oil every month ! How can I get this paid for for free by Hyundai ?

Back in 2024 Brought car in for recall but Hyundai only scanned the vehicle and gave estimate for work done without further explanation. Left the car idle and only start it once in a while. Now when opening oil cap there’s some smoke coming out of it and a rattling sound

While driving, my vehicle stopped moving forward and the engine light came on. I pulled over and called for a tow. The service department at the dealership the vehicle was towed to said that the vehicle had less than a quart of oil in it. I just had the vehicle serviced 2 months prior. The service department changed the oil, oil filter and air filter. They drove the car and heard knocking. They found the rod bearing to be bad. They said it needed a new engine. The vehicle has approximately 51,000 miles. I never had any issues prior to that day. The car manufacture is refusing to replace the engine because I am not the original owner, not because the engine isn't defective. This is a 2019 Hyundai Tuscon with engine 2.0L L4 DOHC 16V. I believe there is a known problem with this engine, but the manufacturer doesn't...

My catalytic converter failed at roughly 70k miles (confirmed by mechanic and replaced). I have now been having transmission issues ever since, starting with the rpms jumping up on their own when trying to downshift (reproduced by mechanic) and ending with the car fully going into limp mode while in the middle of driving on the highway at speed. The former never triggered a light or produced codes, and with the latter the CEL flashed three times at the very start of the breakdown, and then went off and never came back on, despite the obvious problems the car was having.

The vehicle was not repaired because the manufacturer was waiting on the maintenance records for the vehicle. The manufacturer...

The engine sensor knock sensor went out on me on I-95. I called the dealer who sold me the car no action as of yet. Took it to a dealership service and had them diagnose it and they confirmed it. They informed me of a recall for Hyundai that year (2019) but not this model. They were baffled why this model was not recalled when they have several models with engine issues. They informed me they were not going to fix it because it will not work but I could risk it somewhere else. I took it to Precision Auto Tune and the dealership was correct. It only work for 48 hours if that. Confirm by more mechanics and the engine is no good

While driving the car felt like it was going to shutoff multiple times. It had been experiencing an unusually high consumption of oil since it's last oil change. It would also tend to surge and excelarate unexpectedly while driving. The check engine light came on only once and then shut off. The car is currently at the Hyundai dealer. The service person says we need a new engine. These incidents happend while I and my wife were driving in separate incidents at different days and times. I was with my family and had to apply the brakes lest we run into cars in front of me when it surged unexpectedly.
