Power Train Problems of Hyundai Tucson - part 1

While stopped at a traffic light, the engine began producing a loud metallic clattering and clanking sound, consistent with connecting rod bearing failure (rod knock). There was no prior warning light or indication of this specific failure. When the light changed, the vehicle would not accelerate normally, leaving me stalled in a lane of moving traffic. I was forced to make an emergency turn to get the vehicle out of the way of oncoming and crossing traffic. The engine would not hold an idle afterward and has not run since. The vehicle was towed to a Hyundai dealership, where a service department employee stated by phone that this 1. 6l turbocharged engine family has a known, documented history of severe factory defects affecting the connecting rod bearings.

Good morning the problems I am having with my 2025 are very discouraging. Started October of 2025, my tire light illuminated stated the tires were low when they are all at correct specs when using an air guage to check. November of 2025 while driving at night the headlights suddenly shut off briefly then came back back on. January of 2026 while leaving work the transmission would not shift, held accelerator pedal to floor but could not go above 20 mph all the way home for 3 miles. April of 2026 the right side of navigation screen went completely black, shut vehicle off twice and on third restart the screen reilluminated. June of 2026 same thing with the screen going black. I have had my tuscon at the local dealer here in my town for supposedly a repair that they state was a "coaxel cable" behind the dash that was fixed that was causing this issue. I also had the recall performed for the front view camera software update but it is still showing not completed. This is very frustrating to be having experiencing these kind of issues on this new of a vehicle. Clearly something is going on with the software or something and the dealer keeps telling me they are not finding anything wrong. I am a service advisor myself at a small independent shop so I understand the terms they are using but something needs to be addressed to correct the issues that I am having. It is scary when driving and the screen goes black or driving at night and losing the headlight functions. I would appreciate if somebody will look into this and reach out to me to get some kind of remedy for why this is happening. I am paying alot for this vehicle and to say I am satisifed is an understatement. I have purchased Hyundai as my choice of vehicle due to the quality, great warranties and good reviews from other consumers however I am seriously thinking of exploring alternative makes as I do not want to keep going through this. Plus the engine consumes oil. I have attached p/w for review as well.

While driving on a us highway, the check engine light illuminated and the vehicle lost the ability to start/run normally, requiring the vehicle to be pulled off the road and towed to an authorized Hyundai dealership. Dealer diagnostic testing found the engine failed a bearing/performance test, consistent with connecting rod bearing wear. This failure mode — check engine light, dtc p1326, abnormal noise, or a no-crank/no-start condition caused by connecting rod bearing wear — is described in the manufacturer's own internal dealer service bulletin covering an engine warranty extension program for multiple engine families (theta ii mpi and nu gdi engines) across several model years and vehicle lines. That bulletin acknowledges the failure as a known condition and extends coverage to 15 years/150,000 miles for original and subsequent owners. The failure occurred suddenly and without warning while the vehicle was in active use on a highway, creating a stall/loss-of-power hazard in moving traffic — the vehicle could not be restarted at the roadside. The dealership's own multi-point inspection performed shortly after intake confirmed engine fluid levels and oil grade were within normal range, indicating the failure was not attributable to a lack of lubrication at the time of failure. Despite this, the manufacturer denied warranty coverage for the repair, citing an inability to produce maintenance receipts for a prior period, even though the dealership's own inspection findings do not support a maintenance-related cause. This report is submitted because of the safety hazard posed by unwarned loss of engine power/starting capability while driving, and because this failure pattern appears consistent with a defect the manufacturer has already acknowledged for closely related engine platforms, raising the question of whether additional vehicles with this engine design should be included in that existing warranty/defect campaign.

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 driving my 2018 Hyundai Tucson limited 1. 6l turbo with the 7-speed ecoshift dual clutch transmission (dct), the vehicle has repeatedly failed to engage and hold gears, resulting in loss of motive power in traffic. Diagnostic scanning retrieved codes p074b (unable to engage gear 3), p074b71 (unable to select 3rd gear), p074b07 (gear dropped out of 3rd gear), p092177 (1st gear system referencing failure), and p0921 (gear shift forward actuator circuit range/performance). A Hyundai dealer diagnosed the failure as requiring transmission replacement at approximately 93,000 miles. This is the same 7-speed dct and the same failure mode addressed by NHTSA campaign 16v628000 (Hyundai recall 149) and Hyundai service campaign t1b, which covered 2016–2017 Tucson vehicles but excluded the 2018 model year despite using the same transmission. Hyundai has acknowledged this defect in 2018 vehicles through TSB 21-at-014h and TSB 22-at-007h, which prescribe a tcu software update, but issued these as service bulletins rather than a recall, so owners were never notified. When I requested the TSB software update, the Hyundai dealer refused to perform it. This defect creates a serious safety hazard: the vehicle can drop out of gear or fail to accelerate without warning while in traffic, increasing the risk of a crash — the identical hazard NHTSA cited in granting recall 16v628000. I request that NHTSA review whether the existing recall scope should be expanded to include 2018 Tucson vehicles.

The contact owns a 2025 Hyundai Tucson. The contact stated that while in reverse, several warning lights illuminated on the instrument panel, and the vehicle suddenly reversed without depressing the accelerator pedal and crashed into a light post. The air bags did not deploy. There were no injuries sustained. The contact sought medical attention after being overwhelmed by the experience. A police report was not filed. The contact was able to drive the vehicle, and the vehicle was taken to the dealer, and the front-view camera was updated; however, the dealer was unable to determine the cause of the failure. The vehicle was taken to imperial body shop to repair the body damage. After the software update was performed, the contact became aware that the vehicle failed to turn off immediately, and several attempts were needed to turn off the vehicle. On another occasion, the contact was able to turn off the vehicle; however, the engine continued to run. Several attempts were needed to turn off the vehicle. The manufacturer was made aware of the failure. The manufacturer opened a case for the failure. The failure mileage was approximately 7,500.

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.

The contact's son owns a 2023 Hyundai Tucson. The contact stated that while driving at various speeds, various warning lights illuminated, and various messages were displayed on the instrument panel; however, the warning lights disappeared upon restarting the engine. The contact stated that her son was forced to restart the vehicle after the vehicle failed to accelerate from a complete stop on one occasion. The vehicle was taken to the dealer for diagnosis; however, the dealer was unable to diagnose or duplicate the failure. The contact was informed that the vehicle could not be diagnosed unless the warning lights were illuminated. The manufacturer was notified of the failure, and a case was filed. The contact later received a letter from the manufacturer confirming the dealer's information. The vehicle had yet to be repaired. The failure mileage was 21,000.

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.
