Other Fuel System Problems of Hyundai Santa Fe - part 1

I do not know what caused this. Here is what happened. While parking the car suddenly accelerated, over the curb, on the sidewalk narrowly missing the building because I turned hard right to avoid the building and I was able to brake to a stop glancing off a concrete pillar. We could have been hurt crashing into the wall/windows, anyone on the walk would have been hurt & anyone in the store could have been hurt. The car was towed to hatchette Hyundai-east waiting to be looked at. There is no police report because it was private property and no damages except to my car. No warning lamps or messages. I remember 2 previous incidents that happened recently. While driving in normal city traffic, my passenger asked if I had speeded up? it was morning traffic, so I didn’t really think about it. Later that day while returning home there was a weird thing that happened. Again, in traffic, the car engine did something weird, but I thought it was the car reacting to the car beside me being too close. It was like it downshifted, slowed down and then resumed normally. The only other time I had any problem was on may 9th near lawrence, KS. The car began vibrating and felt like it was going on rumble strips when I accelerated and did not get up to speed. If I let off the gas it quit. I had the car taken to mccarthy Hyundai-lawrence, KS. They diagnosed an issue from the computer codes and completed repairs having the car from Monday until Wednesday.

The vehicle repeatedly loses motive power while being driven at highway speed. It slows even with the accelerator pressed to the floor, does not shift into higher gears, and drops to 40 to 50 mph. On [xxx], the vehicle lost power at highway speed while I was driving. I had to stop on the shoulder of the hwy. The vehicle could not be driven and was towed to the dealer. The dealer opened r. O. No. [xxx] on 9-3, recording mileage in of 23,595. It inspected the vehicle and confirmed the concern. It replaced the fuel rail pressure sensor (part no. 35342-2m400) under warranty, confirmed a good idle with no codes, and performed a test drive of about three miles. The dealer reported the vehicle ready on 9-15-26; mileage out 23,596. On [xxx], within a few miles of picking up the vehicle after the first repair, the malfunction indicator lamp illuminated. We returned the vehicle to the dealer the same day; the dealer recorded the mileage in as 23,602. The myhyundai app shows active diagnostic trouble code p00bd00 (mass or volume air flow "a" circuit range/performance — air flow too high), powertrain system, recorded at 23,600 miles, with a listed date of [xxx]. The dealer returned the vehicle on [xxx]. On [xxx], four days after the 2nd repair, we brought the vehicle back to the dealer. We reported that it was idling high, at about 1,200 to 1,900 rpm while stopped, and that we had heard a low clicking sound since the repair. The dealer did not keep the vehicle. The next morning, [xxx], about 7 miles from home, the vehicle lost power on a bridge on [xxx]. It slowed to about 50 miles per hour and did not appear to shift. I stopped on the bridge with my [xxx] daughter in the car. Vdot responded. My husband and I switched cars. [xxx] then drove the vehicle. After about two miles it again lost power, and he had to leave the highway and use secondary roads at low speed to get to the dealer. The car is currently at the dealership.

My vehicle had a very strong gas smell inside and outside of the car. I found a gas puddle under the car coming from the back of the vehicle. Car was hesitating when I stepped on the gas. I was afraid it may stall. I drove the vehicle to my regular service station. Vehicle has an active fuel leak and this is a fire hazard. I was very concerned whether the vehicle would stall and cause an accident. Warranty coverage was denied.

My vehicle recently received the Hyundai 9c2 emissions upgrade they required and since then the vehicle has had predictable acceleration issues for the first several minutes after the vehicle. While trying to slowly accelerate the vehicle with unpredictably lurch forward. Many people have been reporting this.

Bought this as a used vehicle with around 77k miles. The SUV was running fine for a little while until I drove onto the highway. It eventually began to bog down and there was hesitation and jumping instead of acceleration. This continued my entire trip home with the check engine light on. The car was only driven for about 300-400 miles in the time I had it. When I brought it to have an oil change, they found metal shavings in the oil. From what I’ve been reading, this has been a common problem for this vehicle. It has been sitting in a Hyundai service center for at least a month now with no real responses from Hyundai themselves. They told me they would not fix the problem due to lack of maintenance from prior owners and that they were marking my title (doesn’t make sense since I bought this with a clean title). According to what Hyundai told me, this issue was brought up by a previous owner in January 2026 with no repairs. How can you change the status of my title while refusing to repair a problem caused by a manufacturers defect?.

At approximately 67,000 miles, the vehicle experienced a sudden vibration when accelerate and decelerate. Engine light was on and vehicle had a hard time to maintain speed above 40mph. Cars were honking behind us due to the lack of speed on road. It happen all of a sudden and cause me and my wife panic at first. The car was took to the closest dealer ([xxx] Hyundai [xxx]) and they found the problem was due to an internally leaking fuel injector, requiring a complete out-of-pocket replacement. This is a known, widespread manufacturing defect directly addressed by Hyundai technical service bulletin TSB #25-FL-001h (which supersedes 23-FL-002h-1). The bulletin explicitly states that 2021–2022 Hyundai Santa Fe 2. 5l gdi engines suffer from premature internal fuel injector failure caused by internal filter breakage, forcing owners to pay out of pocket for a design flaw acknowledged internally by the manufacturer. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

Symptoms are those described in Hyundai recall 236 (delayed shifting,hesitation, stalling). Vehicle has had multiple tsp services at Hyundai but symptoms persist intermittently. Software updates do not fix issue. Hyundai dealer has no other remedies.

Update odi complaint number: 11759237 subsequent actions and manufacturer refusal to remediate safety defect: ?following the [xxx], acute safety incident—where the vehicle lost motive power and entered severe limp mode on [xxx] immediately upon release from sheehy Hyundai of chantilly—the vehicle remained in dealer custody for 11 days (August 20–August 31, 2026). ?failure to diagnose core defect: despite recurring total power loss, active diagnostic trouble code p00af00 (turbocharger boost control module performance), and four consecutive turbocharger destructions within 20,000 miles, the authorized dealership refused to conduct internal engine diagnostics, drop the oil pan, inspect the oil filter, or perform borescope checks. ?physical contamination documented: on August 29, 2026, an on-site physical inspection confirmed sparkling metallic particulate suspended in the engine oil on the dipstick and substantial oil blow-by/intrusion into the turbocharger air intake line. ?formal denial of safety/warranty coverage: on August 31, 2026, dealership management and Hyundai motor America (consumer affairs case #[xxx]) formally denied warranty assistance and refused engine teardown under the theta ii lifetime engine warranty settlement. Coverage was declined citing "outside influence" due to an aftermarket turbocharger assembly, while Hyundai refused to investigate the underlying engine failure contaminating and destroying the forced-induction system. ?evidence preservation: on August 31, 2026, the vehicle was towed to an independent facility to mitigate road hazards, conduct teardown diagnostics, and preserve the engine oil/filter for iso-accredited spectrographic laboratory analysis. ?the manufacturer released an unsafe vehicle into traffic on August 20, 2026, and subsequently refused to investigate or remedy a documented internal engine failure that creates sudden, recurring loss of motive power. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

The vehicle suffers from recurring, sudden loss of motive power and transitions into engine "limp mode" while driving in active, heavy traffic. This severe drivability defect has occurred on four separate occasions under diagnostic trouble code (dtc) p00af00 (turbocharger/supercharger boost control "a" module performance) and related boost/map faults (p0234). During these episodes, the vehicle abruptly loses acceleration capability without warning, creating an acute collision risk when navigating highway traffic and intersections. The turbocharger assembly has required replacement three separate times due to recurring oil contamination from the engine crankcase. Despite meticulous maintenance (documented synthetic oil changes every 3,000–5,000 miles since new), the manufacturer and dealership have repeatedly blamed peripheral turbo components rather than diagnosing or repairing the root cause (I suspect excessive engine crankcase pressure/piston ring blow-by based on the significant oil deposition on the turbo, map sensor, and pooling in the intake line).

Gas needle not going down took and dropped off at lee Hyundai of fayetteville north carolina 28309 8/15/2026 picked it up 08/17/2026 they claim they drove it six miles but they didn’t told it was supposed to be that way sold we filled up when we left the dealer ship drove 78 miles needle still not moving.

Vehicle began running sluggish, gas smell noticed. Vehicle was due for oil change, took car in for oil change to aaa and mentioned gas smell. Aaa identified gas leaking from fuel pump posing immediate safety issue that needed to be resolved.

I took my SUV to get the 9c2 recall on 8/7/2026 performed and took it home. The next morning when I cranked it and left my driveway it acted as if the vehicle didn't recognize that I was pressing my accelerator. It sputtered and hesitated acceleration for about five minutes. It also acted as if it was not going to change from first to second gear. After about five min. Of playing with the gas pedal it straightened out. Twice I was almost hit by other cars expecting me to pull away from a stop sign. I took it back the next day telling the service agent what was happening and he kept it overnight. I received a text saying the technician was unable to find a cold start problem and it was ready to pick up. I was so mad I could barely hold my temper. I took it home and for the next week every single day it acted like this when cold started in the morning. I took it back to premiere Hyundai of harvey and was treated rudely this time. They acted as if they never had a single other complaint and told me I might have to leave it for several days so they could cold start test it for several days. This was on a Wednesday morning 8/19. I was never updated or called and when I texted my service rep on Monday 8/24 I was told the tech was not able to duplicate the complaint and to come pick it up. I will not ever buy another Hyundai because of the way I was treated and lied to. Please create a recall for this badly handled recall 9c2. My sante fe sport ran beautifully before this recall messed up my SUV. Now I have found if I let it idle for five minutes in the morning and accelerate slowly until it changes gears, most mornings it will run well, but if I crank it and pull into the street on a cold start it does the sputtering help us Hyundai owners.

Over the past month, on two occasions my vehicle has emitted gasoline fumes filling my garage, and today my interior cabin smelled like gasoline. Additionally, after warming up, my vehicle experiences acceleration drop/stuttering when accelerating after idling. This happens every day. I took the car to two dealerships (san tan Hyundai and chapman Hyundai scottsdale) and they weren’t able to diagnose the issue.

I was merging onto the highway and the acceleration stopped working and the vehicle would not go more than 25 mph. Had to restart car in shoulder, isue seemed to self correct but then it happened 10 minutes later stranding me in between the highway and exit ramp. This was a huge safety issue and myself and others lives were at risk. I am bringing the vehicle in for inspection but this seems to be a recurring Hyundai issue. There were no warnings that came on. The auto mode on the dash went from green to an amber color. When I restarted the vehicle nothing changed. After the second time it occurred a check engine light came on.

Hyundai sante fe hybrid 2025 has a bad factory seal on the high voltage harness - hybrid battery connector that causes water to intrude the connector under normal conditions which can short the battery and pose a major safety issue. Hyundai is refusing warranty coverage of my shorted hybrid battery on my brand new 2025 Hyundai sante fe hybrid stating “flood” with no evidence of flood damage. My car experienced multiple p engine hybrid system faults on xxx and would not drive. I had it towed the van Hyundai carrollton on that date. They did not look at the car for over a week and it sat on their lot the entire time. On xxx they finally inspected it and claimed the car had been “flooded” and shorted the hybrid battery. The only evidence they provided was moisture in the high voltage harness. There were no water/silt lines, any other damage to any other components, and no evidence of any water anywhere else on the vehicle. The video they showed of the undercarriage only showed normal splash marks from driving. The car was never flooded/submerged. Any water/moisture found in the harness would have been due to a faulty/defective factory seal that should be impervious to water under normal operating conditions. No water/flooding/submersion damage would have been obvious of this. The dealership refused to provide any evidence and had no follow-up. One key aspect they refused to acknowledge was there was a massive rainstorm in [xxx] onxxx which was also the only rainstorm in the area in the previous 1-2 months. This happened while the car was on the dealer’s lot. The car had no issues with any water prior to being at van Hyundai. A case was opened with Hyundai corporate and the dealship also lied stating the car wasn’t in their system until xxx, which is false as I have phone records, tow records, and appointments showing the 7/10 date, so corporate overlooked that. I disagreed with the dealerships diagnosis as it was a scapegoat finding putting all blame o information redacted pursuant to the freedom of information act.

Complete unmitigated loss of acceleration and power while traveling at highway speeds, creating an immediate life-threatening road hazard. Following a warranty engine replacement and mandatory dealer software flash at clay cooley Hyundai (sherman, TX), the vehicle began experiencing powertrain communication issues. While operating the vehicle at 65 mph on the highway, the vehicle completely failed to accelerate and lost propulsion power, nearly resulting in a catastrophic rear-end collision with an oncoming 18-wheeler semi-truck. Dealership diagnostics claim "no trouble codes present," but live data telemetry confirms the high-pressure fuel pump (hpfp) is actively commanding and delivering a dangerous 1,600 psi to the fuel rail at hot idle. This abnormal fuel delivery is paired with a severe powertrain stutter in 3rd gear. Service personnel at multiple locations confirm a widespread, high volume of transmission failures and severe drivability issues specifically tied to this recent Hyundai software update. Corporate has denied repair coverage. The vehicle remains an active highway safety hazard and is completely undrivable.

Complaint summary: [xxx] / engine thermal fire risk / warranty deception my 2019 Hyundai Santa Fe (2. 4l gdi engine) is experiencing severe powertrain degradation under the known theta ii engine defect class-action framework. On November 7, 2025, the vehicle logged a permanent diagnostic trouble code (dtc) p1326 via an independent scan, indicating catastrophic internal rod bearing wear. On xxx, the vehicle was brought to Hyundai of milledgeville for safety recall verification. Instead of executing the mandatory corporate-directed bearing clearance test (bct) to replace the failing engine block, the service department committed technical campaign malpractice. The technician forced the 9c2 ecu software update directly over the locked mechanical fault to suppress the dashboard warning lights and alter the vehicle's rom id parameter limits. When caught via a photograph of their active gds diagnostic tablet showing 7 historical system faults, the service manager provided a truncated printed report hiding page 1 and omitting the critical p1326 powertrain code count to evade a warranty engine replacement. Due to these unmitigated delays, the vehicle has suffered severe consequential safety damage. The advanced engine degradation and oil consumption have flooded the exhaust system, melting the catalytic converter substrate and triggering a new dtc p042000 (catalyst efficiency) fault immediately after the dealer visit. The extreme engine vibrations have also damaged the transmission's torque converter clutch (dtc p074100). The dealership refused a service loaner and knowingly sent a disabled consumer and an elderly passenger away in an active, failing vehicle that presents a sudden stall-on-highway hazard and a severe thermal exhaust fire risk under extreme summer heat conditions. Hyundai motor America corporate has failed to provide emergency towing or alternative mobility accommodations despite a registered corporate case file.

Hyundai performed recall #9c2, on 7/2/26. Since that time, the engine has a full time miss. When it is cold, it will hesitate, kick and buck. Hyundai is aware of this. Their solution is to warm the car for 3 to 5 minuets before moving. What happens if there is an emergency and you can't wait? possible accident with injuries trying to pull into, or cross traffic! I have filed a case with Hyundai, and they just update that they are aware and working on a solution with no expected date for the software fix. This is a serious problem, and they need to fix soon! also, when an engine runs like this, over a period of time it will destroy the catalytic converter. Who's going to pay for that??.

Latch system for fuel tank door failure.

After a recall repair (campaign 9c2) was performed on my vehicle, it developed a hesitation and lack of acceleration issue that did not exist before the repair. The vehicle exhibits rough or delayed gear shifting, a noticeable lack of power/acceleration, and behavior that feels like the engine is not receiving adequate fuel. This occurs both during cold start and after the vehicle has been driven and is fully warm. I returned the vehicle to the dealership (wallace Hyundai), where the service advisor personally test drove the car with me and confirmed he could feel the hesitation firsthand. Despite this, the dealership stated no issue was found and advised warming the car up for 1-3 minutes before driving as a workaround. I tested this exact recommendation, and the issue returned even after the vehicle was fully warmed and had already been driven. Hyundai motor America's national consumer affairs department has stated this is "under review" but has also described the hesitation as "normal" cold-start behavior related to catalyst warm-up. This does not match what I am experiencing, since the issue also occurs when the vehicle is already warm, and their own dealership's advisor confirmed the problem exists. I have also noticed a decrease in fuel efficiency (mpg) since the software update associated with this recall. This issue directly affects the safe operation of the vehicle — specifically the ability to accelerate reliably, including in situations like merging onto highways or pulling into traffic, where a lack of power could result in a collision. I do not consider the vehicle safe to drive in its current condition.

The door to the gas tank is a push door which is temperamental. I can be at the pump and push the door to pop it open and it won't. I'm at the point where I have to pop my gas tank open before I even get to the gas station because to pull up to the pump and not be able to put gas in the tank is a waste of time. There is no lever to flip along side the driver seat because it is a push to open door. . It is available for inspection, however, it is temperamental. I will video it so I have proof as it works and it doesn't work. It has not been inspected by anyone only because if it is a defect in the motor for the door, I want Hyundai to recall it. I have gone on youtube to see if there are remedies and yes, there are videos on how to open the door in case you cannot push it open. I cannot do this because I'm not ruining the back of my car as there is no compartment to open as shown in the yt video. I am not one to let my tank get down to less than 1/2 tank, especially not now. But why am I worrying about popping the door open when I'm not even at the gas station yet??.

I own a 2017 Hyundai Santa Fe sport 2. 4l (VIN: [xxx]). On xxx, my vehicle received campaign 9c2 (ecu software update for theta ii emissions improvement). Shortly after this update, I began experiencing a drivability issue that did not exist beforehand. Description of the issue: the problem occurs only after the vehicle has been sitting long enough for the engine to become completely cold, typically overnight. During approximately the first 1/4 mile of driving, the vehicle intermittently jumps, surges, or lurches while accelerating normally. Once the engine warms up, the symptom completely disappears and the vehicle drives normally for the remainder of the trip. There are no warning lights, no check engine light, and no diagnostic messages. The Hyundai dealer has had the vehicle for nearly a week but has been unable to reproduce the concern. Because the issue only occurs during the initial cold start and first portion of the drive, I am concerned that it may not have been tested under the same conditions in which I consistently experience the problem. I am not claiming that campaign 9c2 caused the issue, but the timing is notable because the symptom began only after the ecu update was performed. I am requesting Hyundai's assistance in determining whether: - the ecu update was installed correctly, - any required adaptation or relearn procedure is incomplete, - there are any related technical service bulletins or software updates, or - additional diagnostics should be performed during a true cold-start drive with live data recording.

Hi, my name is [xxx], I bought used hyndai santafe sport 2017 from dealership in 2020. It had around 47,000 miles on it, intitially it was running fine but after driving 2 years I discovered that engine is burning oil and after the oil change right after 1000 miles I had to add a quart of oil and it was like every two weeks. I had many srevices from dealership and other auto mechanic stores but it didn't improved. I had no choice but to keep driving the card on xxx th the engine crashed with out any sign on dashboard. There was slight noise and it increase by the way car was parked on the side road from highway. The car was towed to my local mechanic and confirmed that engine is crashed. After I had to towed to dealership and I am still waiting for their response. Now we have put 43,000 miles in 6 years (91,000) total mileage. I had bought the waranty from dealership by $ 2500 which expired in 2025 currently no warranty. My question here is that the car is still under 100,000 and engine failed. What if the dealership refuse to replace the engine. What are my leagal rights. Thanks [xxx] [xxx] [xxx] information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

After the ecm recall for a software update the car would not run correctly. It jerks and and runs rough. It almost stalls when you put your foot on the gas. I took it back to the dealer and they can not get the problem to duplicate. Noone else has looked at the problem. There were never any problems with the care until the recall. The problem occurred the day I brought the car home from the ecm update.

We have a 2017 Hyundai Santa Fe sport with a refurbished engine due to a past class act settlement, we were notified by Hyundai to bring in the vehicle for service campaign 9c2 to update the engine control module (ecm) software for vehicles equipped with the (2. 4 gdi) theta ii refurbished engine, which we have. The morning after we updated the 9c2 software, after starting our car cold for the first time in the am, our car went into limp mode, shaking very badly, it would not accelerate above 20 mph, it had a lot of trouble shifting from 1st to 3rd gear and acted like it was going to stall out and then die in the middle of the road while I was in the car with my 2 children. The dealership we took it to was not able to duplicate the limp mode, but has documented that they did witness hesitation and sluggishness while test driving it. I cannot validate that it was test driven cold immediately as requested as all their test drives were done without me. Due to the vehicle not accelerating as it should normally, I feel the vehicle is very unsafe and unreliable as well. I’m willing to provide more documentation, and our car is available for further inspection. I did request the help of a Hyundai customer relations case manager who stated Hyundai is aware of all of the drive-ability issues I have stated and he said they are hoping to provide another software update, but that time frame is unknown. Dealership mechanic stated the same thing and believes our issue is related to the 9c2 update. The manufacture has not inspected the vehicle, but we would absolutely love them to if they would. There have been no check engine lights come on before or after this update, only misfire codes came up after the update which dealership has those, and since the dealership was unable to witness it going into limp mode while driving it, they could not gain the much needed data that pinpoints the exact problem. We were advised to warm up car and rev up the rpm to above 2,000 before driving.

No power till car warms up for 5 minutes. It will be jerky on highway. The gas mileage is going down drastically, I was doing 32 miles to gallon and now it's 22mpg. All this is after the recall we just had performed. I have no power trying to avoid accidents, taking off from stopping. Car smells weird now.

Took car to dealer to have oil changed on April 29, 2026 and was told they had also preformed a software update, service campaign 9c2. Everytime since that day after the car has set for a little while and the car is restarted driven it stalls and surges really bad several times lasting for several minutes. It also can do this at random at anytime but not constant like it does when first started. This is very dangerest for obvious rasons and needs to be fixed. Although there is others reporting the same problems on line and a person making the same complaint while I was wating at the dealership. They say "they are unaware of the problem and I will have to leave my car for up to three days or more to have it checked out and then they will let me know what needs to be done” and what the cost will be. I only have the one vehicle and they would not provide a loaner vehicle so needing my car every day I can not do without it. Due to the fact that Hyundai refuses to acknowlage the problem. There really needs to be a recall to have this problem fixed.

After my Hyundai dealership performed a recall on emissions my Santa Fe sport started having problems on cold starts. After it has set for a few hours when I would put into gear and start to driving the car acted as though it was trying to flood out. I have to feather the accelerator and drive very carefully for at least 1/2 - 3/4 miles. This is very dangerous and make me very uncomfortable driving. I took my vehicle back to my Hyundai dealer and the mechanic told me they were waiting for a recall to the recall. How stupid!!! it has been over a month and nothing has been done to fix the problem. Please advise!.

Directly after the dealer, johnson Hyundai of apex, completed service campaign 9c2 on 4/28/26, my vehicle began sticking, surging, and harshly changing gears. I have followed up with the dealer multiple times. They said they are not getting back any diagnostic error codes (outside mechanic shop also confirmed they're also not seeing error codes), but went ahead and recalibrated the ecm. They told me to drive for 200 miles and the issue should be resolved. I have now driven 1,500 miles and the issue persists. I'm now seeing Hyundai put out a 'driveability communication" about this issue, but there is no proposed fix/recall. This issue did not exist before this service campaign was performed by the dealership.

I took my vehicle in to the dealership on April 24, 2026 for a software update after receiving notice in the mail. The update changed my auto stop/start so that it is on whenever the vehicle is started. When removing my foot from the brake the car surges forward without me touching the gas peddle. I took my hyandai back in to the dealership on may 4, 2026, and was told that the auto stop/start was supposed to now be staying on as that was in the software update. They said they could not duplicate the surging of the vehicle. It has surged strong enough to move forward, while stopped at an intersection, that it put me out two to three feet. I felt it necessary to put it in reverse and back up it was out so far. This will absolutely put others at risk as I drive and work in a downtown area with lots of crosswalks with lots of people crossing, and should vehicles be stopped in front of me, it could hit them. I can turn it off, but in the beginning it seemed to be turning itself back on. Additionally, I am not used to always turning it off because I never had to before and I don't always remember. This week, something new: when pulling off after starting the car, even if I remember to turn off the start/stop, the car is jerking forward when I depress the gas. It's like it is getting surges of gas, or like the peddle is being pushed to the floor, let off, pushed to the floor, let off, etc. I am so incredibly scared now to just drive the vehicle I've loved for over five years now. My vehicle has not been inspected by the manufacturer, police, insurance or any others. I did not know this was an option. I would love to get more information about how to go about this. There are no warnings of any kind when this occurs, which is every single time I get in it. Please, someone, tell me what I can do further. Continue taking it back to the dealership? ride with them next time? I just am at a loss and incredibly scared. I am a woman in my 60s.

My 2025 Hyundai Santa Fe hybrid awd was serviced under warranty on 4/22/2026 for a driveability concern after experiencing a loss of power while driving. The service history shows part hy35326-2m500 was replaced. On or about 5/25/2026, the same issue occurred again while driving at highway speed. The vehicle suddenly lost motive power and dropped from approximately 70 mph to approximately 30 to 40 mph, creating a serious safety risk because the vehicle could not maintain speed with surrounding highway traffic. No warning lamps, dashboard messages, or diagnostic codes appeared during the failure. The vehicle is currently at a Hyundai dealership for inspection and repair for the repeat issue and should be available for inspection upon request. The prior dealer record appears to describe the issue generally as a “driveability concern,” but the current repair diagnosis and full repair notes are still pending. It is unknown whether the dealer has reproduced or confirmed the failure during the current visit. I am reporting this as a sudden loss of motive power at highway speed involving the fuel/propulsion system, engine, and/or powertrain.

I am submitting a complaint regarding a turbocharger failure on my 2017 Hyundai Santa Fe VIN [xxx] . The vehicle experienced turbocharger-related failure symptoms including loss of power and drivability concerns. This created a potentially dangerous situation because the vehicle was unable to accelerate normally and could have caused difficulty merging into traffic or maintaining safe roadway speeds. I contacted Hyundai motor America requesting assistance with repair coverage. Hyundai denied assistance solely because the vehicle was outside the warranty period by time and mileage, despite the seriousness of the failure. I am concerned this issue may be related to broader engine or oil-related defects reported in Hyundai vehicles, including possible oil starvation, excessive oil consumption, or internal engine contamination that could contribute to turbocharger damage or failure. I believe this condition may represent a safety-related defect because sudden power loss during operation increases the risk of a crash. I request that NHTSA review this issue and investigate whether similar turbocharger or related engine failures are occurring in 2017 Hyundai Santa Fe vehicles. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

Fuel injector failed the entire engine on my 2022 Santa Fe had to be completely replaced. The dealership put in a new engine. Santa fe is only four years old. That is highly unusual.

The vehicle experienced a sudden, intermittent engine stall while driving, specifically when slowing down or coasting to a stop in live traffic. When the engine dies, the vehicle immediately loses engine power, power steering, and power braking assist, creating an extreme safety hazard. After stalling, the vehicle refuses to restart for several minutes. An authorized Hyundai dealership previously replaced the high-pressure fuel pump under warranty to address this issue, but the dangerous stalling has persisted over the last 2,000 miles. The vehicle continues to randomly shut off without throwing a permanent check engine light or diagnostic trouble code, and the manufacturer has failed to correct this critical safety defect.

Vehicle exhibits delayed deceleration after releasing accelerator. Engine rpm remains elevated for several seconds, causing the vehicle to continue applying power unexpectedly. Issue began after recent repair and was not present before. Condition is intermittent but reproducible and affects drivability.
