We just brought this vehicle in for the ongoing transmission problem (previously reported to your agency after the car self-accelerated), as well as the missed seatbelt recall that was not addressed at the last dealership. I advised the service advisor that the seatbelt recall needed to be fixed. The service advisor contacted us several hours later to tell us that they were replacing the transmission. 10 days later we picked up the vehicle after the transmission replacement, and the service advisor told us they did not do the seatbelt repair, citing lack of parts and/or special order. I asked if this was a safety issue and if I should leave the vehicle with them for longer, but was told not to worry about it, and to bring the vehicle back at another time. Fast forward to today, and the vehicle is rolling forward when we start it. This is worse than the way it rolled forward before the transmission replacement. Coupled with the disregard for the seatbelt recall, I believe there is a serious safety issue with this vehicle. I have notified Hyundai corporate, as well as our attorney, and will be contacting the dealership to drop the vehicle off. I have a video recording of the car rolling forward during startup, but it appears I cannot upload it here. I have forward that video to the above mentioned entities, and am happy to share it with your agency as well.

Hyundai campaign 9c2 recall update: took my vehicle in to have the Hyundai campaign 9c2 recall update performed on the vehicle on June 9th, 2026. Since the update the vehicle is hesitant/jerky upon first drive of the day or anytime it sits more than a few hours. Occasionally it will do this while I am driving. I feel it is a saftey risk because this could cause my vehicle to abruptly hesitate without braking and cause someone to hit me, or worsetransmission to fail while at highway speeds. I took it back to the dealer that performed the required update around June 23rd 2026 and informed them of the problem caused by the 9c2 campaign update. I got the we don't know anything about it causing problems runaround. Even though it has been documented that dealers were notified of this problem. They then wanted to charge me a $100 diagnostic fee to see if it might be something else, I declined that because I know it is from this update. My vehicle ran perfectly fine and smooth before this update was applied and no cel lights are on. I did this update because it was required to be done by Hyundai. When I started researching why my vehicle was hesitant/jerky after the update is when I found that anyone that did this update is having these same issues, and it has been happening for a while now and Hyundai corporation has done nothing to correct this problem other than tell us to sit for at least 3 minutes or more before driving it. That does not help when it does it even after driving for a bit and possibly creating transmission problems.

My 2017 Hyundai Santa Fe (VIN: [xxx]) was brought to herb chambers Hyundai of [xxx], in December 2023 to address the underbody corrosion recall/campaign (9a0). The dealer performed the preventative service. However, the remedy completely failed because the frame was already severely structurally compromised by rust. In early 2024, I relocated to [xxx] with the vehicle. Now 2026, the front subframe sub-assembly deteriorated to a hazardous point, forcing me to spend a large sum of my own money on front-end repairs caused directly by this corrosion. Currently, the rear subframe and rear suspension components are heavily corroded and structurally disintegrated. The vehicle is completely unsafe to drive, presenting an imminent risk of structural collapse and suspension failure while in motion. Hyundai's recall remedy was ineffective and merely masked the rust. The rear subframe (crossmember/cradle) and control arm anchor points are severely corroded, rusted out, and crumbling to the touch, creating an imminent risk of suspension collapse while driving. The extreme corrosion has spread to the metal fuel line the vehicle is unsafe to drive due to the advanced corrosion . Denial of service by local distributor: the vehicle is currently located in the u. S. Territory of puerto rico. I presented the vehicle and documentation to the local authorized distributor, sojitz DE puerto rico (Hyundai of puerto rico). As indicated I brought the vehicle to mvp Hyundai humacao (xxx) and filed a claim (# xxx) however they never sent a anyone to inspect the vehicle or process a safety claim, claiming they bear no responsibility because the vehicle was imported from the mainland, because this is a failed federal safety campaign remedy that now poses an immediate threat to my life and public safety, information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

Driving at 70 mph on interstate, driver adjusted hands on steering wheel and accidently pulled both paddles, shifting car into neutral. Fortunately, there was little traffic, and the driver was able to move to the side of the interstate, out the car into park and shift back to drive. This was highly dangerous. Losing control of the vehicle while traveling at 70 miles an hour could have resulted in death. This feature is completely unnecessary in a family SUV and is going to cause an accident.

My 2019 Hyundai Santa Fe 2. 4l (VIN: [xxx]) is experiencing a severe safety defect involving rapid engine oil starvation. The vehicle recently failed an official oil consumption test conducted by fred beans Hyundai of abington, where it was documented that the engine consumed 1 quart of oil in just 881 miles (PA request #xxx). This vehicle is equipped with the theta ii engine, which currently has active warranty extensions (txxc and txxi) specifically covering connecting rod bearing failure. Despite the documented severe oil loss—which is the primary known cause of connecting rod bearing wear and sudden engine seizure—Hyundai corporate (case #xxx) is refusing to evaluate the vehicle under these warranties. They have improperly classified my claim as a denied "goodwill" request and are refusing to perform a connecting rod bearing clearance test to determine if the bearings have been damaged by this starvation. Because Hyundai refuses to perform the required diagnostic safety protocols, the vehicle must be driven in an oil-starved condition. This poses an imminent and severe safety risk of sudden engine seizure, stalling, and complete loss of motive power at highway speeds without warning, which could result in a catastrophic crash. The manufacturer is ignoring their own failure thresholds and putting driver safety at risk. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

My 2024 Hyundai Santa Fe (VIN: [xxx] ) was manufactured on March 14, 2024, in [xxx] . The vehicle is currently experiencing dual-clutch transmission (8dct) juddering, shuddering, and extreme hesitation when trying to accelerate from a complete stop at traffic lights and intersections. This creates a severe lag in acceleration, leaving the vehicle dangerously exposed to oncoming traffic. This component failure directly mirrors the mechanical hazards outlined in NHTSA safety recall 263. Because my manufacturing date falls just outside the official recall window, this vehicle has not received a formal recall remedy, yet it actively exhibits the identical, dangerous powertrain defects, suggesting the recall's production scope may be too narrow. Furthermore, in November 2024, the vehicle suffered a catastrophic safety failure where it completely lost all propulsion power for approximately 30 seconds while moving through the middle of a live intersection. Most recently, on xxx, right after being released from an extended 38-day service stay at an authorized dealership, the electronic infotainment displayed an active warning screen stating the car should be shifted to park while the vehicle shifter was physically and securely locked in park. Time-stamped video evidence of this active transmission/braking sensor failure has been captured and preserved. The vehicle remains an active, uncorrected threat to my physical safety on the road. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

We have had several transmission issues with this vehicle for over a year. On March 5th we dropped the car off for an oil leak, a malfunctioning middle row seat belt, and an on going transmission clunk and roll. The dealer repaired the oil leak, replaced the seat belt, (damaged the interior of the vehicle while doing so, then denied it) and said they were unable to replicate the transmission problem. The car went back to the dealer again on March 26 for the transmission clunk and roll. They kept it for 8 weeks, and said they couldn’t replicate the issue. I have confirmation that they didn’t even start the vehicle for 4 weeks. We picked up the vehicle on may 22, and the issue persists. Yesterday, when pulling out of a gas station, the vehicle accelerated on its own until I intervened stepping on the brake pedal. When I typed in the issue to google, I was made aware that the vehicle now has a front seat belt safety recall from April 6, which the dealer didn’t even advise us on or offer to repair. I am finding out about this on an interstate family drive and we are of course terrified of driving our vehicle now, based on the unintended accessories and now faulty front seat seat belts. I have asked Hyundai serval times for a buy back which they have refused. Corporate has asked us to bring the car back to the dealer this week, and we are about to sign papers with a lemon law lawyer tomorrow. I wanted to at least file this complaint so that it is in writing should something happen to us in our travels this week. This has all been so unacceptable with Hyundai. We bought this car new and it is paid off.

Vehicle: 2022 Hyundai Santa Fe | current mileage: 140,000 description of safety defect: while operating a 2022 Hyundai Santa Fe at speed, the vehicle suffered a sudden, complete, and catastrophic loss of motive power in the middle of a live, active roadway without any prior warning or dashboard indicator lights. The transmission abruptly dropped out of gear and the engine shut down entirely, trapping the driver and three young children in active traffic and creating an immediate, life-threatening highway safety hazard. The vehicle was towed to sport durst Hyundai in durham, nc, where technicians confirmed a total internal transmission failure where the gears fail to engage. This exact mechanical failure mechanism directly mirrors the severe engineering defect detailed in NHTSA campaign number 22v746000 (Hyundai safety recall 236) for electric oil pump failures causing a sudden loss of drive power. Hyundai motor America corporate case management has issued a flat denial of all safety and goodwill repair coverage based strictly on the vehicle's 140,000 miles, claiming that mileage absolves them of product liability for a catastrophic drivetrain safety defect that endangered three young children. Furthermore, the franchise dealership is actively withholding the gds diagnostic failure scan codes from the consumer, calling them "internal documents" to actively suppress federal evidence of this safety failure. Further, the authorized Hyundai dealership engaged in deceptive practices by refusing to put anything in writing, and refusing my request for any diagnostic information, including any report indicating diagnostic error codes, technician summary, etc.

The vehicle has experienced repeated transmission-related failures beginning at approximately 5,000 miles. The dashboard warning “transmission system error – check transmission oil immediately” first appeared while driving and was accompanied by sudden loss of power. When this occurs, the vehicle loses acceleration and drivability while in motion, creating a safety risk in traffic. The only way to temporarily clear the warning is to pull over, shut the vehicle off, and restart it. Photographs of the warning message were documented at approximately 6,738 miles on [xxx] and again at approximately 12,664 miles on [xxx]. The vehicle was returned to the selling dealer in massachusetts multiple times for the same issue. During the first visit, the dealer drove the vehicle approximately 19 miles but stated they could not duplicate the problem. During the second visit on or about 3/25/2025, the dealer kept the vehicle for approximately six days while providing a loaner vehicle, but again stated they could not duplicate the condition. The vehicle was later inspected by another Hyundai dealer in new hampshire on 8/19/2025 for the same dashboard warning and loss of power condition while driving. That dealer found the transmission fluid level below specification but stated they could not duplicate the warning message during inspection. Following that visit, the transmission warning did not reappear until [xxx], when the same “transmission system error – check transmission oil immediately” warning returned again while driving. On [xxx], the situation escalated into a possible rollaway event. While at an auto detailing facility, the vehicle was reportedly placed in park with the engine running after being repositioned. The operator stated the vehicle indicated it was in park. Moments later, after the operator exited the vehicle, the vehicle moved from its parked position and rolled into a building. The event was documented in writing by the detailing facility. Information redacted pursuant to the freedom of information a.

The contact owns a 2020 Hyundai Santa Fe. The contact stated that while driving at an undisclosed speed, the accelerator pedal was depressed; however, the vehicle failed to accelerate as intended. The contact stated that the vehicle lunged forward. In addition, the vehicle almost stalled. No warning lights were illuminated. The vehicle was taken to the dealer; however, the failure was not duplicated. The contact was informed that no fault codes were displayed. The contact was informed that the issues with the vehicle were just a case of bad luck. The vehicle was not diagnosed or repaired by an independent mechanic or dealer. The contact stated that the failure had occurred shortly after the vehicle was repaired under technical service bulletin: 9c2, in may 2026. The manufacturer was made aware of the failure, and a case was filed. The failure mileage was approximately 74,558.

The contact owns a 2020 Hyundai Santa Fe. The contact stated that he received an unknown service campaign from the manufacturer indicating that a software update for emissions was needed. The vehicle was taken to a dealer where an ecu update was completed and an np001-sc9c2 was installed for the engine and transmission. The contact stated that when his wife drove the vehicle home from the dealer, she noticed that something was wrong with the vehicle but did not specify the failures. The contact stated that the next day, while driving at an undisclosed speed, the vehicle hesitated and shifted improperly, and while depressing the brake, the vehicle accelerated forward. The contact stated that the failure persisted and became more prevalent in the morning after sitting overnight. The vehicle was then taken to the same dealer where a shift engine value reset, transmission value reset, shift adaptations were made (part number 95447-6g200). The vehicle was repaired, but the failure reoccurred the next morning and has persisted every morning thereafter. The manufacturer was notified of the failure and a complaint was filed. The failure mileage was approximately 25,051.

Campaign 9c2 was installed on this vehicle and the now the vehicle is a danger to drive. My wife refuses to drive it as it bucks and jerks as well as the gas mileage has decreased from 35 highway to 28 highway. The fuel trims are way off on cold starts and the transmission now searches for the correct gear. Shifting back and forth. Just a slight touch of the accelerator and the car seems to jump forward which makes stop and go driving almost impossible.

While running errands around town, I noticed my 2023 sante fe 2. 5t was sluggish shifting out of first gear into second. The rpms revved to about 3k before the transmission shifted into 2nd. I didn't notice any problem shifting into 3rd and above. I drove to a gas station for fuel and shut off my car. When I started it and began to drive, I received an immediate warning to take the car to a dealer and the check engine light came on. The car had the same problem getting out of 1st gear at each of the traffic signals I got caught at on my way to the dealership about 2 miles away. The following day, the service department contacted me and determined I needed a new transmission due to the failure of the dual clutch electric high pressure oil pump in the transmission. They submitted a parts request and Hyundai approved a refurbished dct warranty replacement. The transmission only has 50200 miles on it I am second owner but the car was a cpo so I have full warranty coverage. I was given a loaner under Hyundai' warranty provisions. My main concern is that although this vehicle is a 2023 sante fe, it was put in service around August of 2022 and would therefore have the same transmission as the 2021 and 2022s covered under Hyundai recall 236, but this has yet to be acknowledged as far as I know. Please investigate my situation and consider further requirements of Hyundai! sincerely, [xxx] information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

The contact owns a 2025 Hyundai Santa Fe. The contact stated that while driving approximately 65 mph, the vehicle unexpectedly decelerated to 25 mph with a “vehicle will shut down” warning message displayed. The contact stated that the engine then began to shut down, and although the accelerator pedal was depressed, the vehicle failed to accelerate and stalled. The failure occurred on multiple occasions, requiring the vehicle to be towed each time. The vehicle was towed to the dealer; the vehicle was not diagnosed or repaired and the contact was informed that the failure could not be duplicated. The manufacturer was made aware of the failure and multiple cases were opened, the failure mileage was approximately 3,300.

The contact owns a 2024 Hyundai Santa Fe. The contact stated that while the vehicle was turned on and shifted into park, the vehicle unexpectedly rolled away with no warning light illuminated. The contact stated that the vehicle then collided with a tree. The contact also stated that the air bags did not deploy during the crash. No injuries were sustained, and no medical attention was provided. The vehicle was taken to an independent mechanic where full body repairs were completed. The vehicle was later taken to the dealer; however, the vehicle was not diagnosed or repaired. The contact stated that the failure recurred, and during the second incident the contact’s spouse attempted to stop the vehicle and was almost run over. No injuries were sustained, and no medical attention was provided. The contact stated that the their arms and fingers are hurting during the failure, the contact stated that the vehicle then collided with an area of the contact’s home. The contact stated their concern that there vehicle is very hazardous and very unsafe and the failure could have been worse for the contact's spouse. The manufacturer was made aware of the failure. The failure mileage was approximately 32,000.

After the installation of the service campaign 9c2 engine update, the car now seems to surge or rev up briefly at lower speeds like it can't find the right gear or is trying to briefly accelerate. It doesn't seem to be as noticeable at highway speeds, but in residential or low speeds, it's very noticeable and a little unsettling as the car feels like it wants to briefly lunge forward. No lights are on the dash and there is no indication of any malfunction, but it did not behave this way prior to the 9c2 engine program update. I waited for a couple weeks before contacting Hyundai corporate about this issue because I was hoping maybe the transmission or engine was relearning after a battery disconnection, but it has not gone away.

2015 Hyundai Santa Fe limited, 3. 3l lambda ii gdi v6, ~102,000 miles. In December 2022, an authorized Hyundai dealer replaced three specific parts under a Hyundai recall/campaign (records requested). On Sunday [date] at approximately [time] pm, I was driving on [freeway], [state], at 55–70 mph at night. With no prior warning — no warning lights, no chimes, no loss of power buildup, no knocking, no engine protection mode — the engine suddenly and completely died. The failure was instantaneous. There was no limp-home mode and no opportunity to reach the shoulder under engine power. The vehicle lost forward momentum and rolled backward in a live highway travel lane, where it remained stranded until a tow truck recovered it. No injuries. The 12v battery and electrical system remained fully active throughout. The instrument cluster was operational and capable of displaying warnings before the failure. None were displayed. Dashboard warning lights illuminated only seconds after the engine had already died — a post-failure consequence of engine shutdown, not a pre-failure warning. An independent mechanic diagnosed a seized engine due to loss of oil flow. No oil pressure or low-oil light had ever illuminated. The vehicle was then transported to the Hyundai dealer that performed the 2022 service; they promised a diagnostic call and have not provided one or any written diagnostic. This failure mode matches Hyundai TSB 24-em-003h (15yr/150k extended warranty for 3. 3l lambda ii engines in 2013–2019 Santa Fe), NHTSA recall 21v-727 (acknowledging stall risk at highway speed), and the active class action burns v. Hyundai motor company (c. D. Cal. 2025). Hyundai's ksds is documented to trigger a blinking mil, audible chime, and reduced-power engine protection mode upon bearing wear. None of these protective behaviors occurred.

Driving down the highway. Vehicle random alerts that there is a transmission error.

When starting the vehicle, a transmission system error occurs because goes away when the car is shut off then restarted. When the error occurs the vehicle does not accelerate properly.

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.

On April 13, 2026, I arrived home and parked the vehicle, engaging the traditional shifter into the "park" position and turning off the engine. After exiting and standing on the ground to retrieve a purse from the cabin, the vehicle spontaneously and rapidly began reversing. ?as the vehicle gained momentum, I was struck by the driver-side door, which knocked me down and resulted in the vehicle running over me. The vehicle only stopped its rearward movement once it collided with a neighbor's parked car. Only after the vehicle began moving did the horn begin blaring, indicating a delayed rollaway alert. ?this incident resulted in a fractured ankle that required surgical intervention. Despite the traditional shifter being placed in "park" and the engine being off, the vehicle failed to remain stationary, representing a catastrophic failure of the parking pawl or transmission engagement.

3 times now, I am driving and the vehicle goes into limp mode, the "d" on the dash is flashing but the vehicle sends no codes. The tech said the vehicle can immediately delete the code and they can't fix it if they can't duplicate it. It also hesitates when accelerating and is dangerous to myself, my 4 children and anyone driving around me when it goes into limp mode. There is no code, therefore they say they can't do anything about it.

My vehicle experiences severe, unpredictable harsh downshifting/surging when slowing down, specially from 3rd to 2nd and 2nd to 1st gear. The transmission kick causes unexpected vehicle hesitation and deceleration changes in active traffic: presenting an immediate crash hazard. The dealership head technician has physically test-driven the vehicle and confirmed the failure. However, Hyundai corporate is refusing to replace the failing transmission under 10 years/100,000 mile warranty because the vehicle's computer has not yet thrown an electronic error code. The manufacture is actively trying to force me to drive an unsafe vehicle until the transmission completely fails in traffic, putting my family and other drivers at severe risk. May 28, 2026 currently milage is around 88,000. The dealership currently has the vehicle.

On April 2, 2026, the engine in my 2017 Hyundai Santa Fe failed catastrophically while my wife was driving. The vehicle lost power suddenly and completely. There was no warning and no prior symptoms. She was able to pull over safely in a residential area. The vehicle was towed to an authorized Hyundai dealer, where the service representative suspects connecting rod bearing failure—the same failure mode described in NHTSA recalls 17v226 and 17v578 affecting other 2017 Santa Fe vehicles with the theta ii 2. 4l engine. The engine is available for inspection upon request. My VIN does not appear in the recall population, yet the failure is identical to the documented defect. This suggests the recall scope was insufficient. One week prior, we drove this vehicle on a 500+ mile family road trip with our child. The failure that occurred could have happened at highway speed. We are lucky to be alive. No warning indicators appeared before the failure. The vehicle has been regularly maintained. The problem has been preliminarily confirmed by the dealer as suspected bearing failure, pending teardown.

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.

Transmission was replaced under warranty by Hyundai in Nov 2024. Engine was replaced at 100600 miles in Nov 2025. Issues with the transmission were happening at that time but ignored by dealership as issues related to failing engine. Our mechanic confirmed in April that transmission was failing and told us to go to Hyundai. We went to dealer in April 2026. They confirmed transmission needed to be replaced. They were going to contact Hyundai USA. We received no updates despite many calls to the dealer. We had to call Hyundai USA directly. They opened a case. Dealer finally called and took car in and requested good faith repair by Hyundai USA. Hyundai USA responded 2 weeks later and is not covering anything. They replaced our transmission in Nov 2024 with a refurbished transmission that they no longer make. Clearly due to the fact that the refurbished part doesn’t work. They now want me to pay $8000 to repair transmission. My car has been maintained on schedule by my mechanic. All paperwork available. I have had toyotas, hondas and chevys that have lasted close to 20 years. This has been a horribly disappointing experience. And I now need to buy a new car for my 17 year old instead of handing down. I will never buy another Hyundai. I want everyone to be aware of my experience. Disgusting customer service by Hyundai USA.

The 2017 Hyundai Santa Fe was brought to dealership on 3/27/26 for an oil change and a computer update was completed for emissions improvement. Upon picking the vehicle up after service, it was noticeable that it was not shifting correctly. I spoke to the service department and asked if the memory was cleared with the update an if it was having to relearn how I drive and the said it should not be affected. This went on for a few days and I left the car with them to duplicate as there were3 no stored codes. After a few weeks, the teck line recommended a new transmission, which Hyundai offered goodwill assistance. As we were waiting for the transmission to arrive from being on backorder, a bulletin for service campaign 9c2 was release on 5/18/26 that described my experience with shifting issue almost exactly. The transmission was replaced and the drivability issues still persist. Hyundai says that I must let my car warm up for 1-3 minutes to allow a catalyst to reach temperature and not cause rough shifting. This rough shifting is the effect of the update and thus te reason that my transmission needed to be replaced. Further investigation showed that this update is a known issue and cannot be reversed once installed. Currently, I must start my car in 90 degree weather to warm it up as a result of this update which is not logical in any thought process. I have asked Hyundai to cover the balance of the new transmission as this is a result of thier faulty software update with no success.

I purchase the 2017 Santa Fe sport in October of 2023 with just short of 80k miles. It was in great condition and had no issues. I have maintained it according to Hyundai specification and regular on schedule oil changes with recommended 5w-20 full synthetic. At approximately 100k miles, I experienced an oil pressure light on the dash, when checked, the engine was approximately 2 quarts low. From this point on, the engine started consuming oil at an increasing rate all while I maintained regular maintenance. First, 1 quart a month, or about 1200 to 1500 miles, then to 1 quart every 2 weeks or 800 miles. I maintained weekly checks on the oil level and on the evening of 3/24/2026, I had added a quart, bringing the level to the midway point between the high and low dipstick markings. On the afternoon of 3/24/26 while driving on the highway in heavy, but at speed limit, traffic on the highway, I experienced a loss of power and a check engine light. I was able to exit the highway but the car started to run very rough and unable to idle. Luckily, there was no traffic approaching when I turned off the exit and made a left into parking lot to shut off the vehicle. I will be having it towed to a dealership in the next few days for their analysis.

Enterprise car sales sold me this vehicle when it had 3 open recalls on it. The vehicle itself was a problem from the beginning. When I took it in for it's first oil change the mechanic told me it had no oil in it. He said they sold me a car that is notorious for consuming oil and or seizing or blowing up. I had the engine replaced on this car already and I just took it in for it's first oil change and it was already consuming oil. I want a new car but enterprise is telling me this is my problem.

My 2011 Hyundai Santa Fe (approx. 153,000 miles) developed a new stalling and engine-dying-at-idle condition immediately following a knock sensor replacement performed by a Hyundai dealership. Prior to this repair, the vehicle ran normally with no stalling or idle issues. The vehicle was originally brought in for diagnosis related to code p1326, which is covered under Hyundai service campaign t6g (engine rod bearing / knock sensor campaign). The dealership replaced the knock sensor but subsequently claimed my vehicle's p1326 condition did not qualify under campaign t6g. Immediately after the knock sensor replacement, the vehicle began stalling and completely shutting off at idle — a condition that did not exist before the dealer's service. I returned the vehicle to the dealership to address this new issue. The vehicle has now been at the dealership for over three (3) weeks with no diagnosis update, no repair timeline, and no communication from the service department. I am filing this complaint for two reasons: 1. Safety concern: an engine that stalls and dies at idle presents a serious risk of loss of vehicle control, particularly in traffic or at intersections. 2. Service campaign t6g: I believe the underlying condition and the dealer-caused stalling issue are both connected to the knock sensor system covered by this campaign. I request that NHTSA review whether this vehicle qualifies under campaign t6g and whether dealer-caused damage following campaign-related service should be addressed under the campaign or a related recall. The dealership's failure to communicate for 3+ weeks and their claim that my vehicle is not covered under campaign t6g warrants regulatory review.
