I have experienced two near-fatal incidents involving a sudden, uncommanded loss of motive power while traveling at highway speeds (approx. 70 mph). On February 11, 2026, the vehicle entered "limp home mode" without warning, dropping speed to 60 mph and 2000 rpm in heavy traffic. This caused an immediate and dangerous speed differential, nearly resulting in a high-speed rear-end collision. Simultaneously, the ac system disabled, indicating a severe engine protection event. Manufacturer negligence: the vehicle was taken to courtesy Hyundai of tampa twice for this issue (code p0087). They performed a "knock sensor" replacement and cleared data points, assuring me the vehicle was safe. The failure recurred immediately. I subsequently took the vehicle to brandon Hyundai on February 13, 2026. Despite my reports of near-fatal highway failures, brandon Hyundai was instructed by Hyundai corporate to merely repeat the "knock sensor" replacement—a repair that had already failed to resolve the dangerous condition. Critical safety admission: on 02/23/2026, brandon Hyundai service advisor abel gomez explicitly admitted that this repair is "not a fix, it is a temporary thing until it shows again," yet stated they must follow corporate’s directive to release the car. Requested action: Hyundai is knowingly releasing a vehicle with a recurring, life-threatening defect (p0087/sudden power loss) by performing "band-aid" sensor swaps instead of addressing the high-pressure fuel system or internal engine failure. This practice is a direct violation of the safety act. I request an immediate investigation into Hyundai’s refusal to perform permanent repairs on gdi engines displaying these catastrophic failure codes.

I am writing this letter to formally document a series of catastrophic safety failures and gross negligence regarding my 2018 Hyundai Tucson. On two separate occasions, including as recently as Wednesday, February 11, 2026, I narrowly escaped a fatal high-speed collision because this vehicle entered "engine protection mode" while traveling at highway speeds. Incident timeline: previous service: I have visited courtesy Hyundai of tampa twice for engine-related symptoms and code p0087. They replaced the knock sensor and assured me the vehicle was safe. Safety incident (Feb 11, 2026): while driving on the highway, the vehicle suddenly lost power, dropping to 60mph and 2000 rpm (limp mode) in heavy traffic. This sudden deceleration nearly caused a high-speed rear-end collision. Current status: the vehicle is currently at brandon Hyundai (as of Feb 13, 2026). I have been told a review will take 3-5 business days, leaving me without safe transportation or a loaner vehicle. Negligence and liability: courtesy Hyundai of tampa was aware of the recurring p0087 code and engine performance issues. By clearing codes or replacing minor sensors (knock sensor) without addressing the underlying high-pressure fuel or internal engine failure, they released a dangerous, defective product onto the road. This vehicle is clearly covered under the theta ii gdi engine settlement and service campaign 966. The local dealerships are willfully avoiding a necessary engine replacement to save on internal costs, despite knowing the vehicle is prone to sudden failure. Demand for action: immediate loaner vehicle: I require a safe rental/loaner vehicle immediately, paid for by Hyundai, while my car is being inspected. Full engine replacement: I am demanding a full engine replacement as previously indicated by technicians should the light return. Expedited review: I am extremely unsatisfied to be told again I have to wait "3-5 business days" for a safety-critical evaluation of a vehicle that has alre.

Component: engine / electrical system / fuel system incident date: February 9th, 2026 vehicle speed: 45-50 mph description: while traveling at highway speeds on a major roadway, the vehicle experienced a catastrophic and sudden engine stall without any prior warning or dashboard indicators. The engine shut off completely while in motion, resulting in an immediate and total loss of power steering and power-assisted braking. I was forced to perform a high-effort emergency maneuver in heavy traffic to reach the shoulder and avoid a collision. This vehicle is used to transport myself, my coworker and my family whose lives was placed in immediate danger by this failure. Since the start of the financing agreement, this vehicle has a documented history of recurring sensor issues and failed repair attempts at the dealership (route 1 Hyundai). The dealership has previously attempted to address electrical/sensor malfunctions, but the root cause remains unresolved, leading to this life-threatening stall. I believe this is a significant safety defect in the vehicle’s electrical or fuel management system that poses an unreasonable risk of accidents and injury.

The vehicle has consumed the oil and no light came on. I drove and I checked when the running engine start doing a dry noise and loose the power. The stick was completely dry, I filled with 2 litters and now the stick show in the half. My vehicle has 60k miles and tomorrow will check on the servis. It is unacceptable first how the vehicle consumed the oil and the second the system didn't notify risking an overheat and posing an elevated risk to spop in the middle of the road causing an accident or starting a fire due to overheat.

This engine has 70,000 miles on it and has burned a quart of oil every 2500 to 3000 miles, two full quarts between oil changes. In talking to others Hyundai owners, they have similar issues. I have owned multiple other brands of vehicles with well over 150k miles and they did not burn any oil. Fords, bmws, volvos, and subarus.

The contact owned a 2021 Hyundai Tucson. The contact stated that while driving at 10 mph, an abnormal clicking sound was coming from under the hood. No warning lights illuminated. In addition, the contact managed to pull over to the shoulder of the road, where white smoke was noticed leaking from under the hood, and the intensity was increasing while the smoke turned black. The local fire department arrived on scene to extinguish the fire. The source of the fire was not identified. It was unknown if a fire report was filed. A police report was filed. No injuries were sustained, and medical attention was not sought. The vehicle was towed to the contact's residence. The vehicle was deemed a total loss as it was majoily consumed by the fire. The local dealer was not contacted. The vehicle was not diagnosed or repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 65,000.

Purchased used via carvana in sept 2025, check engine light came on while driving it home indicating a pre-existing mechanical defect. We submitted the claim through silver rock (carvana's warranty company) and brought to their approved mechanic. The recommended the following repairs, several that were denied by carvana/silverrock: spark plugs, alternator, serpentine belt, fuel injection service, electrical ignition coil. A month later check engine light illuminated again and through further diagnostics the mechanic found that 2 of the faulty spark plugs were an incorrect model/fit for our vehicle and reported that information which resulted in replacement being approved (a month after initial request). Fast forward to January 2026 we experienced the widely reported knocking noise while driving coming from the engine and had it towed. The damage is a thrown rod and damaged bearing, which is consistent with the current oil consumption litigation, requiring engine replacement. Our 2017 Tucson 1. 6 l turbocharge is not included in the recall. Furthermore, carfax report shows last oil change reported was 2023. Carvana confirms an oil change is part of their 150 point inspection before a sale, however unable to provide me with documentation and failed to report a record of the work to carfax. There are many instances of negligence on carvana's part from failure to provide record of maintenance, which is also failure to adhere to their standard policy, and declining recommended service directly from their approved mechanic, knowing that this vehicle could be impacted by the well known defects through Hyundai. We are requesting assistance with engine replacement meeting safety standards and ensuring consumer protection.

The contact owns a 2016 Hyundai Tucson. The contact stated that the check engine warning light was illuminated, and there was a ticking sound coming from the front of the vehicle. The vehicle was taken to auto zone, where a mechanic diagnosed the vehicle with a knock sensor failure. The knock sensor was replaced. The mechanic informed the contact that the vehicle was included in manufacturer campaign: cs966 for the transmission control module (tcm). The vehicle was taken to the dealer, who confirmed that the vehicle was included and the software update was performed. After the vehicle was repaired, the check engine warning light was no longer illuminated; however, approximately 30 minutes later, the vehicle failed to exceed 35 mph, and the check engine warning light started flashing. The vehicle was returned to the dealer, and the contact was informed that the software update caused the vehicle to enter limp mode to protect the engine. The dealer informed the contact to drive the vehicle for 30 days or a total of 500 -1000 miles, and if the vehicle continued to enter limp mode or failed to operate as needed, to return the vehicle for the engine to be replaced. There were no additional repairs performed. The manufacturer was not informed of the failure. The failure mileage was approximately 125,000.

I have been adding oil to this engine excessively for more than 3 years. . I have had appointments with the dealer where they flat out told me bring it back when the engine fails. I finally got n appointment and was told the engine needed to be replaced. That was 2 weeks ago. . They are now denying the claim. . . Have had my car for 2 weeks. . No loaner. . And decided to deny what they told me.

Following the knock sensor detection system update, this car has a p1326 code that forces it into limp mode. Occurs during moderate-hard acceleration, e. G. Getting on a highway. The car is limited to ?2000 rpm and ? 45 mph, and rapidly decelerates to that speed if necessary. Acceleration is very limited. This occurs roughly every two weeks, despite having a brand new sensor installed by Hyundai. Hyundai has also allegedly performed cleaning on the sensor and related parts. This has been going on since November, when the recall that installed this update was performed.

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.

My 2018 Hyundai Tucson experienced sudden catastrophic engine failure when a connecting rod threw while driving. The engine burned through its oil and the vehicle became inoperable. Hyundai denied warranty coverage for this engine failure because I had not completed the 2021 ksds (knock sensor detection system) recall. I was never notified of this recall. The ksds recall is a software update intended to detect engine knock. It does not prevent mechanical engine failure. Denying warranty coverage due to a software update that I was unaware of raises safety concerns, as engine failure can occur suddenly while driving and creates risk of crash or injury. This appears related to known engine issues in Hyundai vehicles. I am concerned this is a broader safety defect affecting other consumers.

The contact owns a 2017 Hyundai Tucson. The contact stated that while driving at an undisclosed speed, the check engine warning light illuminated. The vehicle was taken to two independent mechanics, and dtc: p1326; was retrieved. The vehicle was not repaired. The contact was advised not to drive the vehicle and to have the vehicle towed to the dealer. The vehicle was towed to the dealer, and the contact was informed that a diagnostic fee would be charged. The contact stated that the TSB: 21-01-023h was performed in February 2025. The dealer was informed that the same failure had occurred. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 92,200.

While driving on a public road, the vehicle experienced multiple simultaneous, dangerous malfunctions: dashboard warnings: all lights illuminated, including engine (flashing), abs, traction control, airbag, tpms, and parking brake, which stayed on though disengaged. Engine & transmission: tachometer fluctuated wildly in park; engine revved without accelerator input. Shifting to drive/reverse caused unexpected “kicks. ” vehicle sometimes failed to move when pressing gas, requiring engine restart. Driving issues: speedometer read 0 or jumped inconsistently. Rpm continued erratically while maintaining speed without accelerator. Steering became extremely difficult. I immediately determined the vehicle was unsafe to drive and returned home with it, which was only a couple miles away. Follow-Hyundai advised dealership diagnosis; they suggested a backup camera module will resolve the issues I experienced in entirety, but also in the same email stated that they could not guarantee it would resolve all of the issues I experienced. This is the second major engine/powertrain failure: first approximately ~70,000 miles (full engine replacement), current approximately ~95,000 miles (approximately ~25,000 miles post-replacement). Recurrence indicates a serious, unresolved safety defect. I am deeply concerned for passenger safety, including children. Other owners report similar issues; the attorney general’s office advised reporting to NHTSA. Summary of safety risks: sudden loss of control/power, erratic acceleration, dashboard failures, steering resistance, unpredictable handling, recurrence of major defect. I am submitting this report to NHTSA to request investigation of these recurring defects. I do have video documentation of all of this, as well as all written communication with Hyundai national consumer affairs and the dealership. I am having a hard time uploading them because of the file limits. Please let me know if any of this will be helpful to you.

At the time of engine failure, my husband was on the offramp between 140n and 24n at approximately 8:30pm. This ramp is under construction and narrow, but state troopers stopped and were able to push the car to the side of the road. As it was nighttime, my husband and /or other motor vehicle drivers/passengers could've been seriously injured. The car did not display any warning lights or signals. The car was then towed home and then to empire Hyundai in fall river, where it was assessed. It was determined that there were 5 outstanding recalls on the vehicle. Hyundai fixed all, with the exception of recall #966, which was issued and not repaired prior to my purchasing the vehicle. Hyundai corporate was contacted by aaron at empire Hyundai. They (corporate) refuses to replace the engine. According to corporate, this should've been fixed by the independent dealer or owner prior to being sold to me.

The car has been diagnosed with internal engine failure by both an independent service center and a dealership service center. The issue was described as a rod timing issue causing knocking, leading to failure of the engine. A light was not on for a majority of the issue but did start flashing before car became completely undrivable. The car was sold to me with this issue and has been driven for nearly 3 years with a power loss issue that was dismissed as turbo lag or other issues. Driving a car with this issue that does not alert with a check engine light is a major threat to driver and passenger safety as it can result in engine seizure and vehicle fires. The engine issues began at the least before 58,000 miles, with total failure occuring at roughly 96,000 miles. Hyundai is known for this issue, particularly in turbo model engines. Only once during ownership of the car did the check engine light come on prior to engine failure. When checked, it was described as a catalytic converter issue. The service center also did an oil change on the car, and the light went off. The check engine light did not come on again for more than a year. The check engine light did not come on until after the issue was diagnosed by the independent service center it was taken to in January 2026.

On January 7, 2026, shortly after delivery of a used 2015 Hyundai Tucson (VIN [xxx] ), the vehicle experienced immediate mechanical failure while being driven, resulting in sudden loss of power and drivability. Multiple warning lights illuminated on the dashboard at the time of failure. The vehicle became disabled and left the occupants stranded roadside in fairhope, alabama. The exact component that failed is unknown at this time. The failure appears related to the engine, powertrain, fuel/propulsion, and/or electrical systems. The vehicle was not operable after the incident. On January 8, 2026, the selling dealership (sandy sansing Nissan, pensacola, florida) towed the vehicle back to their dealership. The vehicle has remained in the dealership’s possession since that date and is available for inspection upon request. This sudden failure created a significant safety risk due to loss of propulsion while in traffic and exposure to roadside hazards. The problem has not been independently repaired or evaluated by the consumer. No manufacturer inspection has occurred to the consumer’s knowledge. The dealer has not provided a diagnostic report or repair findings. No warning lights or symptoms were disclosed prior to delivery. The failure occurred almost immediately after delivery. The vehicle was sold and delivered by a licensed dealership. The sale is currently in dispute because the vehicle became disabled almost immediately after delivery due to this safety-related failure. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

The car keeps randomly dying. Completely loses power even when driving.

The engine, specifically cylinder # 3, has had a catastrophic failure at 114,000 miles. Engine repair shops and engine experts have determined the only fix is a complete engine replacement. Cost estimates are $8500 for a new engine + labor estimated at $2000. Scrap value is estimated at $1000 - $1500 the dealer from whom we bought the car in late 2015 said it is out of warranty. This is unacceptable. Please, please issue a recall on the engine of this vehicle. The vehicle is available for inspection if requested. Failure was catastrophic problem has been confirmed by engine experts the car is not drivable to a manufacturing facility the engine has not been inspected by police nor our insurance company there we no warning lamps or messages symptoms include shuddering at initial acceleration beginning at 75,000 miles dealer said there was no problem and recommended and performed a transmission fluid change.

On my husband's way home from work he explained to me that the car had a "hiccup" and then an engine light blinked on, then it died at an intersection. He was pretty close to home so he got it started again and drove it home. He replaced spark plugs and coil packs and it still had a misfire. We took it to an auto repair shop where they did a scan and told us it had a dead hole in cylinder 2 and that it needs a full engine replacement. The car also had an oil change just before thanksgiving. My husband checks oil regularly and added a quart a month before the oil change and it seems to consume more oil then it should.

The contact owns a 2017 Hyundai Tucson. The contact stated that while driving approximately 70 mph, the vehicle lost power, decelerated, and the check engine warning light started flashing on and off. The vehicle was parked on the left shoulder of the highway and later driven to the right shoulder with the assistance of a state trooper. The vehicle was later towed to the local dealer, who diagnosed that the engine had failed and needed to be replaced. The vehicle was not yet repaired. The manufacturer was notified of the failure, but no assistance was offered. The contact was informed that the vehicle was previously serviced under NHTSA campaign number: 21v727000 (engine). The contact stated that the vehicle had experienced the failure listed in the recall. The failure mileage was 66,000.

The engine is burning excessive oil. Down 3 quarts over approx. 3,000 miles. Mechanic verified there are no leaks - it is burning the oil.

All four cylinders misfired in my car while driving causing the catalytic converter and all four fuel injectors to need to be replaced. My car suddenly stopped driving in a rural area with only a few minutes of warning when the engine light came on. I was not even able to drive to a nearby shoulder. I was stranded on the side of the road in 5 degree weather until a tow truck could come.

Purchased this car used 3 years ago. Followed owner's manual for oil and filter changes. On 1/2/26 the engine seized, had it towed to Hyundai dealership and they will not approve a replacement for the engine because they said I hadn't followed maintenance guidelines. I submitted all receipts and they still are denying. I had the ksds and all Hyundai campaigns addressed which was to extend the warranty and they still deny. No warning lights whatsoever came on until the engine seized on the parkway. Hyundai knows there is an issue with these engines but still won't step up.

My 2024 sel hybrid has a very annoying acceleration delay after a full or partial stop. The delay has occurred many times. It is present no matter which mode the car is on. It is not a matter of slow acceleration, but a 1-2 second delay of anything happening after I press the pedal. This could be a safety issue when you're at a stop sign and you need to proceed and you can't go.

Numerous issues with this vehicle. Now, when having oil change, told by the Hyundai service center that it is using excessive oil and may need a new engine. In researching this problem, have discovered Hyundai has had several problems with excessive oil consumption in their many of their Hyundai vehicles, including the 2016 tuscan.

Engine is burning oil causing the catalytic converter to clog and fail. Hyundai dealership told me after I had the car towed to them for repair on 12/30/2025 that the catalytic converter had already been replaced before in March 2024. I had purchased the car from another dealership March 2025 and the catalytic converter replacement was not on the car fax. I was also I formed by the hyandai dealership that my car has an extended warranty of 10 year/150,000 miles on the engine due to the known oil consumption issue. My car has 131,000 miles. I was told hyandai will make it very difficult for engine replacement since I’m a second owner. There needs to be a recall immediately.

Engine lost power suddenly on the highway. Vehicle entered limp mode and became limited to 45mph and reduced acceleration.

The contact owns a 2017 Hyundai Tucson. The contact stated that while driving at an undisclosed speed, an abnormal pop sound could be heard coming from the engine.
