Power Train Problems of Hyundai Tucson - part 1

My 2022 Hyundai Tucson experience, a sudden transmission failure at approximately 92,520 miles. The vehicle develop shifting issues and abnormal noises before losing propulsión. While driving. Hyundai diagnosed and internal transmission failure and approved transmission replacement. I’m concerned about the sudden loss of proportion and the safety risk this creates. Hyundai proposed repair is to replace the transmission with a rebuild remanufacture transmission rather than a new transmission. I am concerned about the reliability of the repair following a complete transmission failure.

The vehicle severely shudders, jerks, and hesitates from a stop and while making a turn, during both acceleration and deceleration, making it entirely unsafe to drive. The vehicle has been completely un-driveable for the past 6 days. The check engine light illuminated, and on 4/9/26, the dealer documented a failed transmission judder test and kept the car, issuing a loaner. A temporary software patch failed after two weeks. Upon return, the dealer reported they were unable to recreate the problem, recommended returning when the vehicle demonstrates the problem more frequently, and refused to mechanically repair the dual-clutch transmission under my active original-owner 100,000-mile powertrain warranty, basically instructing me to continue to drive a seriously un-safe vehicle. Most recently, a yellow dashboard warning light illuminated, and the vehicle entered a dangerous 'limp mode,' severely restricting power and struggling to move before the light cleared after cooling down. The vehicle is completely un-driveable and parked.

While operating the vehicle on the highway at speeds around 55 to 60 mph, without warning, the engine suffered a sudden, catastrophic internal mechanical engine failure that resulted in an immediate and complete loss of motive power, rendering the vehicle entirely undriveable. The vehicle was towed to an authorized Hyundai dealership for a formal tear-down and diagnosis. They Hyundai dealership technician formally diagnosed the issue as a catastrophic internal "pin failure" (structural failure of an internal engine pin component). This component defect caused a total mechanical breakdown of the engine assembly. Hyundai motor America has issued a corporate warranty denial for an engine replacement, despite the vehicle being covered under the Hyundai engine ii class action settlement (which extends powertrain protections due to widespread internal engine manufacturing defects), a sudden, un-warned loss of engine power while driving poses a severe and immediate safety hazard to the driver, passengers and other motorists on the highway. Hyundai's refusal to remedy this known structural defect leaves a dangerous vehicle un-repaired. I am requesting an investigation into Hyundai's denial of coverage for structural engine component failures on the 2. 0l nu engine platform.

While driving, the engine began making a loud knocking/rattling noise and the check engine light began flashing. The vehicle experienced a loss of power and was unsafe to continue operating normally. The vehicle was taken to a Hyundai dealership for diagnosis. The engine requires replacement. Hyundai denied coverage, claiming excessive oil consumption and/or maintenance concerns. However, upon inspection, the dealership removed the valve cover and advised that the engine was internally clean and showed no significant sludge buildup consistent with severe neglect. I am concerned that this engine failure may be related to known Hyundai engine issues involving the 2. 4l gdi engine. The failure occurred well before the expected service life of the engine and created a potential safety hazard due to the loss of power while driving. I am requesting that NHTSA review this failure and determine whether similar failures are occurring in 2020 Hyundai Tucson vehicles equipped with the 2. 4l gdi engine.

Delayed response when accelerating from a stop.

While driving, the check engine light began flashing and the vehicle shook severely due to engine misfiring. The vehicle has had a recurring cylinder 3 misfire throughout ownership. Spark plugs and ignition coils were first replaced around 40,000 miles and replaced again in December 2025 for the same recurring issue. A Hyundai dealership inspected the vehicle and found codes p0300 random misfire and p0303 cylinder 3 misfire. The dealership technician documented that the piston rings did not look good and confirmed the catalytic converter was damaged as a result of the misfires. The vehicle has had an engine rattle at idle, oil consumption, and blow-by since early in ownership. The engine defect is progressive and predates the current mileage. The flashing check engine light and severe shaking while driving at highway speeds created an unsafe condition with other vehicles on the road. The problem has been confirmed by a Hyundai dealership. Hyundai motor America was contacted and denied goodwill warranty assistance. The vehicle is available for inspection upon request.

The issue involves the vehicle’s drivetrain and hybrid/electronic control system, where the car suddenly jerked forward in stop-and-go traffic on the freeway as if it had been struck from behind. Immediately following this event, the vehicle would not accelerate beyond approximately 40 mph, indicating a loss of normal power. This created a significant safety risk, as the sudden jerking could have led to a rear-end collision, and the inability to accelerate properly made it difficult to keep up with traffic on the freeway. I was barely able to safely pull off the freeway while surrounding traffic continued at higher speeds, increasing the risk to myself and other drivers. The problem appeared to resolve after turning the vehicle off and then back on; however, this raises concern about intermittent failure. The vehicle was taken to a dealership for inspection, but they were unable to reproduce or identify the issue. The vehicle remains available for inspection upon request. The vehicle has been inspected by a dealer but not by the manufacturer, police, or insurance representatives. Prior to the failure, there were no warning lights, messages, or noticeable symptoms indicating an issue. Based on similar reported experiences, this event may be consistent with a “limp mode” condition or a malfunction in the transition between the electric motor and gasoline engine, potentially involving the transmission or hybrid control system.

My vehicle has an ongoing safety?critical defect involving the braking system, powertrain, and adas logic. I have not driven the vehicle since 04/27/2026; all diagnostic trouble codes were recorded while the vehicle was in the dealership’s possession. On 05/05/2026, the vehicle stored multiple dtcs, including c164286, p071300, p076800, u060ff1, u060f29, and u061386. On 05/13/2026, p071300, p076800, u060ff1, u060f29, and u061386 were recorded again, showing repeated powertrain, communication, and control?system faults while the vehicle remained with the dealer. On 05/22/2026, two additional safety?related dtcs (p107600 and c272146) were first recorded, and both were last reported again on 05/27/2026, still while the vehicle was in dealer custody. These dtcs now show as historical because the vehicle has not been operated since the last fault was recorded. Their historical status only means the system has not run a new check — it does not mean the defect is repaired. The vehicle has also exhibited brake?logic abnormalities, including a persistent brake?on signal at highway speeds, which violates brake?throttle override safety logic and affects adas functions. The powertrain shows signs of torque converter instability, mechanical drag, abnormal slip, and heat buildup documented across these dates. Two ota updates were performed during periods of instability, but neither corrected the defect. The dealership has not provided documentation confirming the safety issues were resolved. Because the braking logic, powertrain behavior, and repeated dtc activity remain unexplained and unresolved, I do not believe the vehicle is safe to operate.

Sitting at a red light the vehicle seemed to almost stalled then lunged forward about eight feet almost colliding with the vehicle in front of me. To my knowledge the vehicle has not been inspected by the manufacturer nor has the problem been reproduced by a dealer or independent service center. To my knowledge there were no warning lights, messages or symptoms. I am somewhat unfamiliar with this vehicle since I've only owned it for 5 days. I picked it up on 4-25-26.

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. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

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.

The 2. 0l engine catastrophically failed during normal highway driving, consistent with a thrown connecting rod. The vehicle suddenly lost power on a roadway with tractor-trailer traffic. The driver and a child passenger narrowly avoided being struck by a semi-truck before the vehicle could be brought to a safe stop. No prior warning lamps, no check engine light, no abnormal noises, and no indications of any kind preceded the failure. The failed engine is currently at a Hyundai dealership and is available for inspection. The dealer has confirmed catastrophic engine failure and submitted an engine replacement request to Hyundai motor America. Hyundai motor America declined the engine replacement request, citing incomplete status on service campaign 966 (knock sensor detection system update for connecting rod bearing wear). The owner purchased the vehicle used and was never notified by Hyundai of service campaign 966. The owner also was never notified of NHTSA recall 20v543000 (abs module fire risk), which remains open and unrepaired on this vehicle, demonstrating a pattern of failed manufacturer notification to the current registered owner. This vehicle is a class vehicle in the Hyundai/kia theta ii engine class action settlement (in Hyundai and kia engine litigation), which extended powertrain coverage to a lifetime warranty for connecting rod bearing failure on 2018 Tucson vehicles equipped with the theta ii 2. 0l engine. The failure mode experienced is precisely the defect this settlement and campaign 966 were designed to address. Component that failed: engine, specifically connecting rod bearing/short block assembly. Component is available for inspection. Vehicle has approximately 71,000 miles. The failure created an immediate and severe risk of fatal collision involving a child passenger. Manufacturer has been contacted and has denied warranty coverage. Nhtsa action is requested regarding both the engine defect denial pattern and the unrepaired abs fire-ri.

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.

January 9, 2026, driver was on i25, when driver heard a loud thud and the rpms kept rising but the vehicle would not accelerate. Was very dangerous and barely avoided a collision with other drivers on the road. Barely got it home and shut it off. Tried to drive again but would not get out of reverse. Car was towed to Hyundai dealership for inspection. Ego4 check engine light diagnostic. 120883. Transmission and rear coupler/differential replaced. Test driven and dealership said it drove as designed and shifted as designed. Cost $10,955. 29.

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.
