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.

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!.

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.

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.

Engine light for car read codes po 304 303 420 prior to sale of car per code read out taken when engine light went off shortly after my purchase. Not addressed prior to sale. Codes read and called to dealership. Car taken for service. Reported fuel smell, exceleration issues, short stallings. Same codes. Stated car was " fine. " drivable. Asked for brakes/ rotors to be checked. No documented brake service given. Stated they were "fine. " taken to local brake place next day that confirmed brake rotors needed repair. Car returned after began sputtering. Reported as fuel injector failure. A known issue with this makr and model that shown codes point to that were given to, and read at service center by mechanic at dealership twice. They did not mention replacing catalytic converter, that is damaged from injectors and an emissions issue at time of call regarding repair report. No brake report or inspection requested multiple times to be checked. Did not follow correct protocol to ensure engine was clear of fuel sprayed by injectors into pistons, intake valves, ect. They placed my self at risk for engine fire, sudden car failure. Consistently mislead and failed to do proper reseach and care regarding car issues and hazards it presented. Being a known issue with this make and model it was a failure to inspect for issue. An emissions failure and violation to allow a damaged catalytic converter to be on road. This issue with the car is in class actionable suit. It is not on the recall list. As it damages the whole car systemi including emissions, it should be forced to be on the recall list so dealerships cannot allow potential harm to their customers as well as violating emission laws.

Traveling in a 55 zone on rt 27 and my vehicle lost power and said pull over and charge vehicle with engine on. I did this once and the battery went up to half way charge then I could start to drive again. Less than a half a mile up the road climbing a good size hill by the town’s salt shed—the same issue occurred. I had to pull over again and allow battery to recharge. This is not a complete hybrid, it has a gas engine not sure why the hybrid and gas are not syncing up. Many users on the internet have reported the same issue that I have experienced. Someone needs to investigate this before major injury occurs.

I bought a 2018 Hyundai Santa Fe from a dealership in may of 2023. Ever since then I have paid around $8,000 in repairs for this car. These repairs have been so expensive and time consuming that last year I wasn’t able to drive it for 6 months because it was in the shop for most of the year. I had to fix the fuel pump, the battery, timing chain valve twice, O2 sensor , catalytic converter, engine valve, cylinder 1 & 3 and now I have to fix cylinder 2 & 4 & that cost again around $2,000 to fix. I am constantly stressed out, crying and becoming broke because I have to keep on repairing this car. I use up all of my tows every year because my car always shuts off on me while I am driving. I am at the point where I want a refund on the car and I want to get rid of this vehicle. I do not feel safe driving on the highway or driving with my two kids and I am currently pregnant again and this car isn’t safe for a family. I am constantly feeling broken down and worthless because I can’t even keep this car a float.

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.

I was driving on March 20, 2026 at about 12:00 pm when I suddenly noticed smoke, a strong gasoline smell, an oil smell, and a burning odor coming from the vehicle. I pulled over immediately because I believed the vehicle was unsafe and at risk of fire. The vehicle had to be towed. An independent repair shop later found a fuel leak at the high-pressure fuel line / fuel pump area, a loose ground wire on the right-hand side of the engine, a valve cover gasket leak, and engine timing chain noise. I was informed that gasoline had sprayed throughout the engine bay. This created an immediate fire hazard even though no actual fire occurred. This problem was especially concerning because the vehicle had been inspected and serviced by an authorized Hyundai dealer in December 2025, less than about 3,000 miles earlier. The loose engine ground wire and fuel leak raise serious concerns about vehicle safety and the adequacy of the prior inspection. I contacted Hyundai the same day and reported this as a fire-risk safety issue, but I did not receive timely assistance. Because immediate dealer service was not available, I had to authorize emergency repairs at a local shop for safety reasons. No warning lights were noted before the incident. The failure was confirmed by the repair shop.

My vehicle had oil consumption problems that were fixed with a new replacement engine now my catalytic converter is going bad due to engine oil consumption problems and the dealer I deal with is refusing to help with this issue. There is only around 50k miles on the new engine. I would greatly appreciate your help with this thank you!.

While traveling at approximately 80 mph on the highway, my vehicle suddenly lost all response to the accelerator pedal. Despite continued pressure on the gas, the vehicle rapidly decelerated to approximately 40 mph on its own. There were no warning lights, unusual noises, or physical indicators of a problem before, during, or after the event. I was able to safely navigate the vehicle off the highway. The vehicle appeared to operate normally afterward. The following day, I brought the vehicle to a mechanic who was unable to replicate the issue and found no stored fault codes. No repairs were made. Given the known concerns surrounding the theta ii engine in this model year, I am submitting this incident for documentation purposes and to contribute to any ongoing or future investigation into sudden acceleration loss in 2013 Hyundai Santa Fe vehicles.

2018 Hyundai Santa Fe sport. Purchased January 2026 took to oxmoor Hyundai service center March 2026. February 2026 began using oil at a measured rate of 700 miles per tank of oil. Used 3 full tanks of oil within the month of February. Oil lights and engine lights on and off and flashing during this time. March 8, 2026, engine light flashed and then stayed on continuously. Engine shook and stuttered and made a loud noise. Engine stalled while I was driving at 35-40 miles per hour. I was able to continue driving to my home with the stuttering and stalling. The next morning I drove it to the oxmoor Hyundai service center. I told relayed the timeline of all symptoms I had experienced over the 2 month lifetime of my ownership. They did not attempt to reproduce the issue. They only entered "shakes in reverse" as the customer provided issue on the intake information. Service center performed diagnostic, found cylinder misfires on cylinder 2 and cylinder 4. Replaced spark plugs to resolve cylinder 2. Cylinder 4 continued to misfire. Used borescope and found broken valve. They did not address the scoring on the cylinder of the valve. Recommended engine replacement. Advised it would not be covered under a warranty because the rod did not break. The oil consumption was proven with documentation from multiple valvoline visits and the vertical scoring was present on the cylinder with the broken valve in the borescope photo. The service center refused to do a boring clearance test or any other test that would prove the engine should be covered under an extended warranty or class action settlement. It wasn't until I reviewed hma documents uploaded to the bbb arbitration, that I realized that the information I initially gave to the service center of all the symptoms with timelines had not been entered into the system for diagnostic review by techline. Arbitrator denied my claim under the theta settlement because the rod had not broken yet, but she said my engine was defective.

On March 04, 2026, I took my 2019 Hyundai Santa Fe to the local dealer for oil change service. As part of that service visit, they performed Hyundai recall 9c1 which was supposed to lower tailpipe emissions. The next morning, and ever since, my vehicle ran differently. The engine had several 1000rpm surges and was sluggish at other times. This behavior has continued. Particularly when I first start out in the morning and the engine is cold. Never after the engine is warmed up. A visit to the Hyundai forum shows a growing list of other Hyundai owners who are experiencing the same issues. This recall is defective and should be corrected.

On March 4, 2026, at approximately 7:30 am est, while driving my 2023 Hyundai Santa Fe limited on [xxx] , the vehicle experienced a sudden loss of propulsion while traveling at approximately 70 mph (posted speed limit). The vehicle would not accelerate or maintain speed and would not move forward when placed in drive, indicating a failure within the powertrain/transmission system. The vehicle is currently located at a Hyundai dealership and is available for inspection upon request. This incident created a significant safety risk, as I was traveling at highway speed in active traffic when the vehicle unexpectedly lost the ability to move under its own power. This placed me at risk of being rear-ended and made it difficult to safely maneuver out of traffic. The vehicle was inspected by a Hyundai dealership. Diagnostic trouble code p284001 (shift fork “d” position) was identified, and I was informed the failure is transmission-related. The condition was reproduced by placing the vehicle in drive, at which point the vehicle would not move. The vehicle has been inspected by the dealership. The manufacturer has been notified but has not physically inspected the vehicle. No police or insurance inspection was involved. There were no warning lights, messages, or prior symptoms before the failure. The issue occurred suddenly without any indication of a problem. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

My 2018 Hyundai Santa Fe sport equipped with a theta ii gdi engine began exhibiting excessive oil consumption, engine knocking, and cylinder misfires consistent with the known theta ii engine defect covered under the Hyundai class action settlement. Prior to the failure, the check engine light illuminated and I experienced repeated misfires and audible engine knocking. The vehicle required frequent oil additions between oil changes due to excessive consumption. The vehicle was taken to an authorized Hyundai dealership where a diagnosis confirmed a burnt valve inside the cylinder head. The dealership recommends replacement of the cylinder head or complete engine replacement to correct the issue. The dealership performed a bearing failure test and attributed the burnt valve to carbon buildup. However, excessive oil consumption in a gdi engine directly accelerates carbon buildup on intake valves, as burning oil deposits carbon on valve surfaces preventing proper seating and causing overheating and valve failure. The carbon buildup is therefore a consequential result of the theta ii oil consumption defect, not an independent cause. The safety risk is significant as engine misfires and knocking while driving create unpredictable loss of power and potential for stalling in traffic. The vehicle is currently not reliably operable. The manufacturer has been contacted regarding coverage under the theta ii settlement. The component is available for inspection upon request at the servicing dealership.

While driving on the interstate at 70mph the vehicle’s fuel injectors failed causing the vehicle to lose power suddenly.

After conducting Hyundai service campaign 9c2 for an emission update, vehicle now lunges and lags when accelerator is depressed. Symptoms tend to be more present soon after vehicle is started and reappear less often after the vehicle engine is at optimal temperature. This problem was not at all present prior to the service campaign update. The vehicle had no warning lights prior to the service update. This problem causes a safety issue when acceleration is not consistently present in a time of lane merging and turning onto higher speed roads. There are no warning lamps on the vehicle currently. Hyundai customer service was contacted about problem and I requested to remove the campaign update as this safety problem was not present prior to the update. Hyundai would not attempt to do this and required me to pay a diagnostic fee of several hundred dollar to troubleshoot the source of the problem. I declined.

When I try to open the fuel cover it wont' open. I have to lock and unlock my car, sometimes up to 10 times, to get the fuel fill door to open. This eventually is going to leave me stranded somewhere stranded. Some of my same year and model are covered under recall for this issue by when I call Hyundai my VIN is not covered. I would like it to be covered and repaired.

While on the highway my car lost power, gradually slowing down to a stall. I was able to safely park on the side of the road. I got the car to a nearby dealership that kept it for 10 days. The dealership said that the problem was code p2118 (throttle actuator control motor current range/performance) that the air "flap" was frozen stuck shut and the engine was disabled on the freeway in order to prevent damage. The resolution was "waited for it to thaw and cleared the code". The dealer has a service bulletin and a software update but it did not resolve the safety issue. I've noticed hesitation when accelerating the car from a dead stop as well, which started last year.

The 2025 Hyundai Santa Fe hybrid has had multiple occasions, most recently on February 3, 2026 with 12,330 miles on the car, where the gas-powered engine fails to provide any power to the drivetrain. The car experiences vast power loss and enters "limp mode" where only the small hybrid battery is powering the vehicle. Max speed ranges from 10 - 25mph and there is little, if any, acceleration, even when the gas pedal is pegged to the floor. It is necessary to pull over, engage the flashing safety lights and try to find a safe place to park. After turning the vehicle off and on several times, eventually, the gas engines re-engages. The first incident of this type for this vehicle was on August 7, 2025 with approximately 4,400 miles on the vehicle. It was taken to the dealer, key Hyundai of salem, who could not find any dtcs and could not replicate the problem. They said "bring it back if it happens again. " they next time was on February 3, 2026 where it happened several times on a trip to and from a local restaurant. This time, at dtc code of p088000 powertrain / powerloss was recorded and reported. However, by the time the car was seen by key Hyundai of salem on February 5, 2026, the code has cleared itself. Hyundai's corporate policy is that historical codes can not be used for warranty claims. So, the dealer tried one potential fix, cleaning the tcm connectors under the driver's seat, and returned the vehicle stating that Hyundai corporate would not authorize warranty work unless/until the car was presented to the dealership with a current / live dtc or visible broken parts. It seems unsafe to put a vehicle back on the road that could lose power and drivability at any time for no apparent reason. I am aware that there have been several other reports of similar power loss / limp mode situations by owners of 2024-25 Hyundai Santa Fe hybrids. At the moment, I am told that there is no current technical service bulletin on this from Hyundai.

While driving the vehicle at approximately at 55 mph on a the 826, the engine suffered a sudden and catastrophic mechanical failure without warning. The vehicle lost all motive power in active traffic, creating an immediate safety hazard and nearly resulting in a rear-end collision. Upon inspection, it was determined that the engine assembly, which is a replacement unit provided by Hyundai under the theta ii settlement, with less than 12,000 miles, suffered an internal breach. This breach allowed coolant to contaminate the lubrication system sort of a milky oil, which led to a connecting rod bearing seizure. Despite this being a repeat failure of a safety-recall component and the vehicle being covered under the theta ii settlement lifetime warranty, Hyundai motor America has denied the repair claim. I am reporting this as a safety defect because the sudden engine stall resulted in a loss of power-assisted steering and braking while the vehicle was in motion.

My Hyundai Santa Fe 2019 limited is burning oil. It started after the turbo broke in October 2024. The turbo began leaking oil and then died. I took it to the dealership as it is still under warranty and they replaced the turbo. As a result, I have had issues ever since and now my car burns oil at a fast rate. In between oil changes I need to put oil in the engine to avoid it being drained. I am able to go about 3k miles on synthetic oil and by 2. 5-3k it is almost empty. It has been doing this now since 2024. I just had my 90k mile check up complete and with that I got an oil change. This was done in November 2024. Syntehtic oil was used. On January 16, as I was driving my car mileage decreased, the car began to shake and the engine light came on. I was able to safely stop and have the car towed. It was found that after driving just 2k miles the oil had completely burned off. I currently have an appointment at the dealer for them to run diagnostics on why it is burning. I saw there was a class action lawsuit against other Hyundai's doing the same thing and as a result Hyundai has to replace the engine. I also have read numerous forums where everyone is reporting the same thing with this particular model of it burning oil. I wanted to report this in case there were other owners of the same car experiencing the same thing.

Component: engine (theta ii 2. 4l gdi) / connecting rod bearing-related failure risk with abnormal internal oil loss. The vehicle is available for inspection upon request (engine, oil level condition, diagnostic history, and dealer records). Safety risk: while driving on the highway (approx. 70 mph), the vehicle displayed a low oil warning, and I experienced concern for potential engine seizure/stalling and sudden loss of power, which could cause a crash. I reduced speed and sought service. This condition presents an ongoing safety risk because sudden engine failure can occur without adequate warning. Dealer confirmation: the problem was confirmed by a Hyundai dealer. After a routine oil change, the low oil warning appeared within ~1,700 miles. A Hyundai service center inspected the vehicle and documented the engine was approximately 3 quarts low with no external leaks, indicating internal loss/engine deterioration rather than a leak. Hyundai then required additional steps (combustion chamber cleaning and monitored mileage), and the abnormal internal oil loss condition persisted. Manufacturer inspection: the vehicle has been inspected by Hyundai dealerships, and Hyundai performed campaign-related actions, including ksds/ecm update (t3g) and later knock sensor replacement. No police or insurance inspection. No crash or injury occurred. Warning lamps/symptoms prior to failure: prior symptoms included a check engine lamp with dtc p1326 (ksds-related) documented by Hyundai service in 2025, followed by continued abnormal internal engine condition. The low oil warning occurred while the vehicle was in motion (highway speed). The issue remains unresolved, and I do not feel the vehicle is safe to operate due to seizure/stall risk. Additional: I reported this as a safety defect because similar theta ii engine issues are widely reported and can result in stalling, seizure, or engine fire. Hyundai denied engine replacement assistance despite the documented condition.

Supplemental update – ongoing safety concerns and extended loss of use since submitting my initial complaint, my leased Hyundai vehicle (VIN [xxx] ) has now been presented for service for the third time for the same unresolved safety-related issues. The vehicle has been held by the dealership for eight (8) consecutive days during this service visit with no resolution and no clear timeline for return. Safety concerns remain unresolved, including: persistent toxic/chemical odor inside the cabin random rear hatch opening while vehicle is parked and locked repeated false “windows open” alerts electrical/body control system irregularities to date, I have not been provided with documentation confirming that cabin air quality testing, exhaust intrusion testing, or comprehensive electrical diagnostics have been performed. These unresolved conditions present ongoing safety risks and loss of use. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

My 2021 Hyundai Santa Fe (VIN [xxx] ) is experiencing severe engine instability, including rough idling, hesitation upon acceleration, and intermittent stalling. These symptoms align with TSB 26-FL-001h regarding defective gdi fuel injectors. The vehicle has stalled in traffic, creating an immediate risk of a rear-end collision. Despite being within the 100,000-mile powertrain warranty, the manufacturer is refusing to perform the required diagnostic tests (gds fuel pressure drop test) to identify the leaking injectors. This failure to diagnose a known fuel system defect poses a significant safety risk to the driver and other motorists. The primary safety risk is unexpected engine stalling while the vehicle is in motion or stopped at intersections. Additionally, the loss of power during acceleration prevents the vehicle from safely merging into high-speed traffic, significantly increasing the likelihood of a collision. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

Car had an unintended acceleration. I had been stopped prior to entering my garage. I had started to slowly accelerate when the car accelerated hard. It took a lot of effort to stop the car.

I have a 2020 Hyundai Santa Fe, 2. 0t. I recently experienced the following issues; gasoline fumes coming into the car at low speeds, difficulty starting the car when it is cold and hesitation when trying to accelerate quickly. The check engine light came on and the dealer diagnosed a faulty fuel pump and high pressure hoses. . . . . . On a car with only 49100 miles! the repair cars are estimated at over $1800. This is totally unacceptable and there should be a manufacturer issued recall on the car where Hyundai covers the cost of the repairs.
