Power Train Problems of Hyundai Tucson - part 1

The car was backing out of a driveway in reverse. Came to a stop to shift to drive, and recieved a "shift system malfunction! service immediately" screen message and the car was locked in the middle of the roadway unable to be put into any gear or be turned off. It was a huge roadway safety issue. The tow driver had to search for a code or sequence of commands to put it into neutral to be able to be safely lifted onto the tow bed, and the vehicle was stuck in accessory mode, which effectively drained the battery.

The transmission system failed. The vehicle had previously been serviced at a Hyundai dealership for a transmission-related issue and was returned to me as repaired; however, the problem persisted. Shortly after the repair, the transmission failed again, indicating that the issue was not properly resolved. The vehicle is currently available for inspection upon request. The failure occurred while I was actively driving, creating a serious safety risk due to the potential loss of power and reduced ability to safely control or maneuver the vehicle. At the time, my [xxx] child was in the car, placing both of us, as well as other drivers on the road, at risk. The issue was confirmed by the Hyundai dealership following the initial repair attempt. Despite being advised that the vehicle was repaired, the transmission failed again, and the dealership acknowledged that the transmission remains defective. The vehicle has been inspected by the Hyundai dealership’s service department but has not been evaluated by police or insurance representatives. There were no warning lights or messages prior to the failure. The transmission failed unexpectedly after the vehicle had already been serviced and returned as repaired.

Car is a gas hybrid (not plugin). 3 occurrences over the last couple of months. Car emits a warning sound and a message on the dash says "check hybrid system. Stop safely". Basically right after this message the car starts losing power and stops. Doesn't matter if on freeway or not. You need to find a place to pull over or you stop traffic wherever you are. Looks like hybrid battery is completely drained. Can not be re-created. Dealer has it now for the 3rd time. Dealer in the past have not been able to find cause/cure since this issue is not posting any errors to the onboard diagnostic system. Temporary 'fix' is to power off car, and power back on. Looks like this is a 'known' issue though as its being reported by quite a few people online.

All dash warning lights are on and dash lights have a intermittent bright light surge. Hard to shut off engine and have to disconnect battery for electric power to shut off. Very noticeable hesitation in acceleration starting to drive.

Hyundai Tucson sport 2016 gdi engine. I am the original owner of this truck I have taken care of this truck so much it being my first brand new purchase. No oil leaks nothing! when I first purchased the vehicle I noticed that it would stall when I would accelerate but did not think too much of it since it was brand new. A few years passed started to notice frequent oil changes were supposed to be made. Another few years turbocharger went out had to get it replaced. The engine consumes so much oil at first I thought it was because the turbocharger was out so when I got it fixed I thought that would fix that issue and it didn’t. I got an oil change March 2, 2026 and on March 21, 2026 I was on the highway and the truck started to shake really bad I exited the highway went straight to the oil place they said I had no oil on the dipstick I got another oil change (expensive) and when I turned on the car to leave the car shook again and the engine light was flickering on and off and finally stayed on the dash board. Barely made it home. Got a tow truck to tow it to Hyundai dealership they told me they will not see it unless I pay the diagnostic fee of $200 and even then they think it’s the engine with everything I described to them. They said since there are no recalls on the Tucson that Hyundai will not do anything for me I would have to pay out of pocket for everything. Had to pay the tow truck again to tow it to my house ($250). My car has all the symptoms all the other cars have that they have recalled. This is a huge safety issue because I drive on the highway a lot and everyone knows a car with no oil is extremely dangerous.

Bought the 2022 Hyundai Tucson. It was driving perfect no issues then I hit 52,000 miles and the check engine light illuminated. The vehicle started sputtering and idling hard like it wasn’t getting fuel when the gas was pressed. I was on the interstate and the vehicle wouldn’t go over 35mph. Now the check engine light illuminates off and on when it feels like it.

Wife was driving car and the steering locked up and she could not turn it for about 5 seconds. Second issue was put it in reverse and it would not come out of reverse, she had to turn car off and on 3 times to get it to put it in park or drive. I ran this through my claude ai and it says this is an ongoing problem with the Hyundai Tucson. Please make them fix this before selling anymore vehicles as both are major safety hazards.

While driving at approximately 70 mph on a highway under normal conditions, the vehicle experienced a sudden loss of engine power. A check engine light illuminated at the time of the failure, and the vehicle was unable to maintain normal acceleration or consistent speed. The loss of power created a hazardous situation in active traffic, as the vehicle could not safely maintain speed with surrounding vehicles. The vehicle was later inspected by an authorized dealership, which confirmed severe internal engine damage, including cylinder damage and engine misfire requiring major repair or replacement. No clear root cause has been provided. There were no prior warning signs or symptoms before the incident. Warning signs prior to failure: none observed. The vehicle is available for inspection upon request. Dealer confirmation: yes. Manufacturer inspection: unknown.

My specific Tucson is equipped with 1. 6l turbo and a 7 speed dual-clutch transmission. I see there are recalls for the 2016 models equipped with the same transmissions, so I'm concerned as to why there hasn't been a recall for the newer models. My transmission was replaced by Hyundai when the car only had approximately 15,000 miles (give or take) and now at 73,000 miles, I'm experiencing the same issue again! the delayed engagement when accelerating from a stop has been stressful, to say the least. I hope this can be taken more seriously and investigated further. Just take a Tucson, like my version, through a starbucks drive-through and you'll understand just how awful the shudder is. It gets so bad, I worry that the vehicle will shut off.

"on [xxx], my 2016 Hyundai Tucson (VIN [xxx] ) experienced severe engine power loss and mechanical noise under load while driving uphill, creating a dangerous safety situation. This occurred 2 days after a dealer visit (February 19, 2026) where an open ksds service campaign (TSB hce22-14-e600-tl, issue 10d021) — directly related to engine monitoring — was left incomplete. The dealer subsequently denied an engine evaluation citing mileage over 150,000, despite the open campaign having no mileage restriction and despite a prior verbal commitment to cover repairs. Multiple follow-up attempts by phone, email, and whatsapp have been ignored. " information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

As of today, March 17, 2026 , my 2025 Hyundai Tucson keeps having safety issues. On March 8th , 11th, 14th and 25th the car once again shut down mid-drive. This issue occurred last month as well but dealership claims no dtcs were found. I am noticing that the forward collision warning comes on without any cars or objects in front periodically since the purchase of my car. The light will remain on for a few seconds and disappear. The automatic brake system seems to be causing issues as well which I believe causes the car to shut off completely mid-drive. Once the car shuts off the panel lights turn on to include the engine light, but then after a few seconds I able to change gears back to park in order to turn car back on and continue driving. This has happened now several times since last month. However, I have had issues with my brand new vehicle since I purchased it last year. My car remained in the dealership for 3 months last year due to an engine, ac and power train issues. Prior to the car shutting off, no actual warning lights illuminate other than the forward collision warning light and the notification of headlights are turned off even though it’s daylight and headlights do not need to be turned on . Periodically and intermittently an alert about consider taking a coffee break alert has also popped up in the past. It seems Hyundai has a severe issue with the fca operating system and over 100 complaints have been made about this vehicle nationwide and no recalls have been issued. I am afraid for my life and the life of others on the road as this car should not be stopping and shutting off while driving for no apparent reason.

I am dealing with this issue where I am getting fuel injector issue and getting cylinder 3 misfire and air fuel imbalance code. It comes and goes. I spent 1500 bucks flushing fuel system and replacing spark plugs and coil. But the issue is still there! I changed the battery and got it to dealership they said they could find the issue. I was on freeway going southbound near exit 34 when the car starts shaking and I lost acceleration.

My car had a ksds knock sensor detection system campaign 966 installed in 2022 specifically to active if having rod bearing wear. Towed my car to Hyundai under the txxm warranty and they said my bearing clearance was ok and I need new lifters and timing chain cost for repair $2900. I have asked for the full rod bearing wear test report and they will not provide it. They have had my vehicle for 20 days now and I am out of work on disability. Hyundai service center is generally expected to provide you with a report following a rod bearing wear test (often referred to as a bearing clearance test or by a related service campaign, such as t6g or TSB 21-em-004h). Here is what you can expect regarding reports and documentation: documentation of results: the dealership should provide a copy of the results, specifically noting if the bearing clearance passes or fails. Proof of inspection: if the test is performed under a recall or service campaign (e. G. , campaign 966, 982, or t6g), they are required to document the inspection, which you can request for your records. Evidence of damage: if the test results in a failed diagnosis, technicians often take photos of the engine internals, such as metal flakes in the oil pan or excessive wear, which are used to support the warranty claim. If the test passes: if your vehicle passes, ask the technician to print a copy of the results. If the test fails: a formal diagnosis of rod bearing failure, confirmed by this test, is required for engine replacement under the extended 15-year/150,000-mile warranty. Hyundai - recalls +3 this is a safety issue without the full rod bearing report to consumer.

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.

This has happened at least 6-10:times. We park the car put it into park and the car lurches forward. Once the car hit a sign in front of it, a few times to hit the transient in the ground in front of the car. Car was taken to the dealer and the mechanic could not get the event to occur. Nothing occurs prior to the vehicle lurching forward. Issue has been reported to the manufacturer case number assigned but manufacturer refuses to do anything about the issue. Case number is 42145096. As I have written to the manufacturer - we are concerned that this may occur with a sold wall, another vehicle or good forbid a human being in front of the car.

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.

Burning oil at a rate of 2 qts per 1000 miles driven. Known issue in these models of Tucsons. Not covered by the class action lawsuit as this VIN was not identified. It is burning oil at a catastrophic rate. The problem has burned through multiple catalytic converters that were covered under the warranty but did not solve the underlying problem. Has been burning oil since owning the car a year ago.

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).

On December 27, 2025, while driving, the engine suddenly lost power and the vehicle entered limp mode and became undriveable. A warning light appeared and diagnostic code p1326 was later confirmed, indicating engine bearing failure. The vehicle could not be driven safely and required towing to a Hyundai dealership the following day. The engine failure caused a loss of propulsion safety risk. The vehicle remains out of service pending a full engine replacement. The vehicle is available for inspection at a Hyundai dealership.

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.

My car has been burning through about 2 quarts of oil every 1000 miles. Hyundai will not replace the engine. If this continues my engine could malfunction while driving. This is a serious safety concern and there's plenty of information on it. They refuse to recall it.

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.

While driving on the interstate at highway speed, my 2017 Hyundai Tucson lost power without any warning lights or prior symptoms. The vehicle experienced an immediate loss of propulsion while I was traveling in traffic, creating a dangerous situation because surrounding vehicles were also moving at highway speed & I had to quicky maneuver the vehicle to the shoulder with no power. The vehicle had approximately 73,861 miles at the time of the failure. After the incident, the vehicle was taken to a Hyundai dealership and diagnosed with a burned exhaust valve requiring replacement of the cylinder head & valve. The estimated cost of repair provided by the dealership was approximately 7550. The vehicle had no prior warning lights or symptoms before the sudden loss of power. A sudden engine failure resulting in loss of propulsion at highway speed presents a serious safety risk to both the driver and surrounding traffic. This was an extremely dangerous failure.

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.
