2019 HYUNDAI TUCSON Recalls, Complaints & Safety

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 contact owns a 2019 Hyundai Tucson. The contact stated that upon entering the vehicle, there was water overflowing from the front passenger's side floormat. The vehicle was taken to the dealer, but the water entry point could not be determined. Additionally, the contact stated that several unknown warning lights were illuminated. The vehicle was taken to the dealer, where a brake sensor was replaced; however, the failure recurred. The vehicle was taken back to the dealer, where another brake sensor was replaced; however, the failure persisted. The vehicle was taken to the dealer, who diagnosed that the wiring harness had sustained water damage and corrosion due to a clogged sunroof drain. The dealer determined that the wiring harness needed to be replaced. The vehicle was not repaired due to the cost. The contact stated that the repair should be covered by the manufacturer because the failure was a factory defect. The manufacturer was not contacted. The failure mileage was approximately 30,000.

Catalytic converter and oil leak which is causing the vehicle to lose power. The catalytic converter was replaced in 2024 and now is bad again in 2025. Oil consumption has been a problem since 2024. Hyuandi is refusing to repair the vehicle. Despite the engine making a knocking noise and the check engine light is flashing the vehicle is still under the 150,000 power train warranty

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.

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.

My windshield wipers quit working in the middle of a snow storm. I’ve seen there’s a re all on some 2019 Hyundai Tucson’s for the wiper motor. Wondering why mine isn’t included.

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.

My 2019 Hyundai Tuscan has been burning oil and the oil has to be topped off every 1,000 miles or so. There are multiple check engine lights illuminated: abs, front collision, traction. These lights have flashed off and on for 3 years but are not light up solid. This sounds like an issue.

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 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.

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 contact's daughter owns a 2019 Hyundai Tucson. The contact stated that his daughter had parked the vehicle and left it unattended while in the on position. After approximately 10-15 minutes, the daughter attempted to shut off the vehicle by turning the ignition key from the front passenger side, but after powering off the vehicle rolled backwards down the driveway, also dragging the daughter. While rolling backwards, the front passenger door hit the concrete mail box, and the vehicle continued to roll across the street before stopping in the neighbor's yard. During the incident, the daughter attempted to activate the emergency brake, but was unsuccessful. As a result, the daughter sustained several bruises to the right leg/knee and the back area, which did not require medical treatment. The passenger side door and the concrete mail box were damaged. The police were called to the scene, but no report was filed. The cause of the failure was not determined. The manufacturer and local dealer were not yet notified of the incident. The failure mileage was unknown.

1 injured

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.

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

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.

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 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.

Oil consumption

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.
