Power Train Problems of Hyundai Tucson - part 1

When my wife was driving our car on the highway today to work, the car suddenly threw a "check hybrid system - pullover safely" light when she was at highway speeds. She was able to luckily pull over quickly onto the shoulder before the car completely powered down. This is incredibly dangerous. She had to click on the reset 12 volt hybrid battery button in the car to get it started again but the complete loss of power at highway speed was very upsetting.

Hyundai Tucson has been jerking and shaking for over over 4 years now and either when taking to the dealership they reset the dual clutch and have replaced the same part twice in the dual clutch. This shaking has been happening since the car was bought brand new like a year after. The vehicle now will get stuck in gear and while driving will go down to 20 mph and get stuck in that speed. This is a serious safety issue. The dealer could replicate the shaking but not the gears being stuck. It has happened on more than one occasion and they just reset something but this continues to happen. There are no warning lights when the gears get stuck it just happens while driving and it has happened twice now in the last 3 weeks.

On January 7, 2026, shortly after delivery of a used 2015 Hyundai Tucson (VIN [xxx] ), the vehicle experienced immediate mechanical failure while being driven, resulting in sudden loss of power and drivability. Multiple warning lights illuminated on the dashboard at the time of failure. The vehicle became disabled and left the occupants stranded roadside in fairhope, alabama. The exact component that failed is unknown at this time. The failure appears related to the engine, powertrain, fuel/propulsion, and/or electrical systems. The vehicle was not operable after the incident. On January 8, 2026, the selling dealership (sandy sansing Nissan, pensacola, florida) towed the vehicle back to their dealership. The vehicle has remained in the dealership’s possession since that date and is available for inspection upon request. This sudden failure created a significant safety risk due to loss of propulsion while in traffic and exposure to roadside hazards. The problem has not been independently repaired or evaluated by the consumer. No manufacturer inspection has occurred to the consumer’s knowledge. The dealer has not provided a diagnostic report or repair findings. No warning lights or symptoms were disclosed prior to delivery. The failure occurred almost immediately after delivery. The vehicle was sold and delivered by a licensed dealership. The sale is currently in dispute because the vehicle became disabled almost immediately after delivery due to this safety-related failure. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

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.

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.

As I was pulling into a parking space in a parking garage, the vehicle's engine revved, tires squealed and then the vehicle propelled forward on its own, without my foot being on the accelerator. The vehicle only stopped when it hit a support column and the wall of the parking structure. There was extensive damage to my vehicle and to the parking structure wall. My safety and the safety of others was put at risk due to the car accelerating on its own. The problem has not been confirmed or reproduced by the dealer, but we did take the vehicle to the dealer for inspection and they said they could not find anything wrong with the vehicle that would have caused the unintended acceleration. The vehicle has been inspected by the manufacturer, the insurance company and an investigator for Hyundai. Hyundai infomed us that they are not taking any responsibility for anything that occurred and that they will not share their investigator's report with us. There were no warming lamps or messages related to the problem prior to the failure. However, there have been other occasions while driving on the open road when the engine has revved on its own and I told Hyundai about that. In doing our own research, we have found that there are other 2023 Hyundai Tucson drivers who have had this exact same problem (unintended acceleration causing a crash) while pulling into parking spaces. Additionally, the air bags did not deploy during the collision and therefore the incident was not recorded by the edr.

I am reporting a serious safety and reliability concern with my 2025 Hyundai Tucson. At only about 2,000 miles, I was informed by the Hyundai dealership that the transmission has already failed and needs to be replaced. This vehicle is essentially brand new and should not be experiencing a major powertrain failure so early in its lifespan. The transmission issue has caused significant concern regarding the safety of the vehicle. Sudden failure of a major drivetrain component creates an increased risk of loss of power, unpredictable drivability, and unsafe operation in traffic. This is especially concerning because this vehicle was already given to me as a replacement for a previous Hyundai Tucson that qualified under my state’s lemon law. A transmission failure at such a low mileage indicates a possible manufacturing defect or a systemic quality issue that could affect other consumers. I am requesting that NHTSA investigate this matter to determine if this is part of a broader problem in the 2025 Hyundai Tucson model line. This situation is unacceptable for a vehicle this new, and it raises serious concerns about long term safety and reliability. I am seeking further review and action so that other consumers are not placed in similar unsafe situations.

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.

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.

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.

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!.

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.

- kept regular 5k-6k oil changes since 2022 when I purchased the vehicle -took the vehicle to a Hyundai dealership, multiple times, to ask about the engine stalling at a stop or slow turn, and/or jerking. -July '25 new oil change and flushed engine -October'25- no engine or oil lights. Engine seized and needs to be replaced. - VIN didn't populate recall but the symptoms are the same.

I've taken the vehicle to several mechanics for engine-idling when turning, going up-hill. I've purchased new plugs, lines, engine cleaners, no-one can figure it out. The oil now has engine shavings even though the oil was recently changed. The car broke down today.

I am submitting this complaint due to a potential safety-related engine failure that occurred while my vehicle was under dealership repair. My vehicle was dropped off at huffines Hyundai on October 2, 2025, for a fuel injector issue and has remained under the dealership’s exclusive possession since that date. I have not driven or had access to the vehicle after drop-off. During the repair process, I was informed by dealership staff that an injector was seized in the fuel rail and difficult to remove. Although the injector replacement was documented as a short repair, the work was delayed and completed on October 16, 2025. Immediately following this repair, on October 17, 2025, the engine was documented by the dealership as having low compression. I was not notified of this condition until October 27, 2025. The engine damage occurred while the vehicle was under dealership control and immediately following a repair involving seized components. The diagnostic documentation provided to me is incomplete and does not include compression psi values or supporting data. I am concerned that improper repair or handling may have caused internal engine damage, resulting in a condition that could lead to engine failure or unsafe operation. Due to the circumstances and lack of transparency, I do not feel the vehicle is safe to operate and am concerned about the risk of engine failure.

Issue was first noticed in October 2025 - there are roughly 70k miles on the vehicle. It is a 2017 vehicle, and has regular service (oil, inspection). There was a class action lawsuit for this issue (wylie v Hyundai), which was settled prior to the purchase of the vehicle. Vehicle stutters when shifting into and out of first gear. A local mechanic and Hyundai both confirmed that it was a transmission defect. The Hyundai dealership initially thought it was an actuator issue, but has since said that it is a faulty gear assembly. It has a dct (dual clutch transmission). Vehicle suddenly stops and is erratic when driving. Coming out of a stop risks the vehicle shuddering; going through an intersection or turning cross traffic is extremely dangerous as the vehicle could stop momentarily and cause a collision. Vehicle is unable to maintain flow of traffic. The problem appears to be widespread - there are various forums we found where others have this same issue. There were no warnings on the dashboard prior to the issue. When issue appeared a check engine light was displayed.

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.

I purchased a brand new vehicle with only 12 miles on it. Less than 72 hours later I had to have it towed. I turned the vehicle on and tried to put it in drive and 2 error messages came up. One was the check hyrid system and the other was a check engine. The diagostic tool on the car says it is related to transmission. The dealership doesnt have time to look into it yet and the manager from the dealership I bought it from offered no solutions since I travelled home to another state.

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.

My Hyundai’s replacement engine, installed under a recall a little over a year ago, is now failing again. Hyundai’s service department was the only shop to ever work on the engine. There is visible silicone drooping from the area where the head and block were torqued down — a defect hidden beneath the engine cover that isn’t removed during normal maintenance. Hyundai corporate acknowledged silicone use would be “shoddy work,” yet refuses further review, stating they’ve “never had a customer dispute something within 18 months later. ” if Hyundai engines arrive sealed and shops don’t handle insulation, silicone should not be present. This may indicate poor workmanship or improper installation on recalled engines. I request NHTSA review this as a recurring safety and workmanship issue on Hyundai recall replacements.

My 2017 Hyundai Tucson limited 1. 6l turbo (with 7-speed ecoshift dct) has ongoing transmission problems. The vehicle hesitates, jolts, and sometimes fails to accelerate from a stop, which creates a serious safety risk when entering traffic or crossing intersections. The problem has been reproduced and confirmed by the Hyundai dealership in fairfield, CT. They diagnosed the transmission and recommended a complete replacement at a cost of over $7,000. This issue matches the defect described in NHTSA recall 16v628000 and Hyundai service campaign t1b, which involved the same 7-speed ecoshift dct in 2016–2017 Tucson models. However, my VIN was not included even though I am experiencing the exact same safety defect. No warning lamps appeared before the hesitation/judder began. The safety risk is significant because the vehicle can fail to accelerate as expected in traffic, increasing the chance of a crash.

While driving my car to virginia to see my daughter, the oil light came on in the middle of a highway, where the speed limit was 70, the car slowed down and I had to pull off to the shoulder as the car lost all acceleration, making it very dangerous on a highway I waited for about 2 hours for a tow truck I waited for almost 2 months to get my car back and it happened again after having it back for a little over a week mind you, I bought the car brand new with 45 miles on it and the first problem happened a little over 2 weeks after I bought it hopefully this can be resolved so that my car doesn’t spend more time being serviced than me driving it.

Excessive oil consumption, full synthetic oil last less than 2000 miles. Transmission takes some time to respond when start driving from a stop. Car shake a bit.

While driving on the highway at normal speed, the vehicle suddenly lost power and shut off without warning. There were no warning lights or messages prior to the loss of power. I was able to safely pull over, but the engine would not restart at that time and the vehicle required towing. The sudden engine shutdown occurred in active traffic and created a safety risk due to loss of propulsion. The vehicle later restarted, but I brought it to an authorized Hyundai dealership for inspection. The dealership diagnosed internal engine damage, including piston ring failure and cylinder wall scoring, and advised that the engine would need to be replaced. Since the incident, the vehicle has shown intermittent oil pressure warning lights and reduced performance. The issue has been confirmed by a dealer inspection. The vehicle is currently not considered reliable or safe for regular driving.

Car would not go over 25 mph. Had to pull to side of the road. I had to turn the car off and on then it ran normal.

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.

Fuel injector failure. Car was losing power completely when pressing the gas pedal then would suddenly catch and go again. Then go very slowly with little power, almost got into an accident because of the loss of acceleration. They replaced the fuel injectors and it is now happening a second time with the check engine light coming on again. A recall needs to be made! several of the same complaints on here!!!!!!!.

I was driving on the highway, about to change lanes, when I looked in my rear view mirror and saw black smoke coming from my appeared to be my exhaust. I immediately started to pull over, and that is when the oil light first appeared on my dashboard. By the time I had put the car in park, the check engine light had also appeared. After calling my boyfriend and a tow truck, I exited the vehicle and noticed a large pool of oil by my front tire. With the car on the tow truck, I could see oil continue to drip out. The car was towed to the local Hyundai dealership. Since this occurred on a Saturday afternoon, the service dept. Was closed, and Hyundai called me on Monday, Aug 11, 2025 to explain that I should contact the auto mechanic that last changed my oil, as the oil plug had fallen out, and my engine had seized. (had I not noticed the smoke right away, I could have been in an accident on the highway when the engine seized. ) I explained to Hyundai that I had my oil changed 3,000 miles ago, and hadn't seen any indication of oil leakage, nor had the oil light come on prior to the incident on Aug 9, 2025. Hyundai insited I contact the oil change mechanics as it was clearly a craftsmanship defect, not the fault of Hyundai parts or material. Hyundai provided photos showing the oil plug was still laying on the block. I visited superior auto (mechanics that did the previous oil change) and they also deny responsibility due to the fact that the car drove fine for 3,000 miles without any indication of oil leakage, so there is no proof of fault craftsmanship.

I recently purchased this car and just took it on our first highway trip of about 1100 miles. I experienced three problems that are a safety concern. 1. "need to take a coffee break notification. " this comes on frequently and is distracting. No need to have that come on. When driving in heavy traffic at speed, this is too distracting. There is no way to turn it off. 2. Camera focused on the driver. If I take a drink from my water bottle, looking around the water bottle to see the road, the camera can not see my face/eyes. It then shuts off my cruise control, makes a noise, scares my wife, and distracts me from driving. This has happened to me in heavy urban traffic going through cities on my last trip. 3. The cruise control is linked to communication from outside the car. When driving in the mountains, there are times when the signal is lost, the cruise control stops working, the car emits a noise signally a problem, my wife screams, I lose concentration on what is going on as the car decelerates quickly and the semi truck behind me comes very close to the rear of the car. Potential accident caused by this silly system. There is no way to disable "adaptive cruise control" and resort to a system that does not rely on outside communication. The car has about 3000 miles on the odometer and I am ready to trade it in/get rid of it. I am greatly disappointed.

My car is a 2023 Hyundai Tucson plug-in hybrid with approximately 75,455 miles on it. The car is stuck in neutral and will not switch to any other gears. The car also will not turn off fully. I basically got stuck/stranded and could not move. Had to be towed.

The car will fail to accelerate when turning at a stop and starting at times. It’s very dangerous b/c you can be at a complete stop on the highway and try to start going and the car will sputter out. There is no doubt that something is wrong with the transmission and has been for a year but didn’t register until 12,000 miles later. The car only has 70,000 miles in it. I kept taking it to Hyundai to be looked at and they kept telling me it was just how the dual clutch transmission works. Now a year later they say it’s registering as a problem but don’t want to cover it under the warranty b/c I’m a second owner. If I was the original owner, it would be covered. If you look at the history of this year and make, you can see there have been issues with this car. I am extremely upset they aren’t willing to cover the cost. This is my [xxx] daughter’s car and this has been extremely dangerous to drive. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

Excessive oil consumption no leaks its buring oil.
