Other Fuel System Problems of Hyundai Santa Fe - part 1

While traveling out of state, my 2022 Hyundai Santa Fe (2. 5l) experienced a sudden loss of power and rough running during acceleration to pass; check engine light came on. Independent shop pulled code p0302 (cylinder 2 misfire). Vehicle became unsafe to drive and was left at a Hyundai dealer in indiana. I later learned Hyundai issued TSB 25-FL-001h (Jan 2025) for 2. 5l gdi injector internal filter breakage that causes misfires and directs replacing all four injectors. Parts were quoted up to three weeks on backorder. This sudden power loss during highway passing presents a safety risk (inability to accelerate/merge). Vehicle is under 60,000 miles.

I am the current owner a 2017 Hyundai Santa Fe sport. While I was driving my SUV on the highway at highway speeds at 60mph, the oil pressure and the check engine warning light illuminated all of sudden after around 1 hour of smooth ride. In the meantime, suddenly the vehicle lost motive power, the steering wheel seized and smoke came immediately. Losing motive power in running conditions and smoke coming out during failure could have endangered our lives. The smoke came out due to leakage of engine oil probably. The vehicle was stuck in the middle of the road. The vehicle was towed to the residence and then after Hyundai dealership. The dealer was made aware of the failure. The failure mileage was approximately 76,245 only. Before reporting to nhsta I have seen numerous complaints about high oil consumption and burnt valves on theta ii engines around 2017 santafe sport model and very similar occurrence of events happening to all while driving the vehicle on highways. Hyundai must need to provide support to this year model and make vehicles.

Bought car in 2022 when covid was still a problem. I had problems with the led screen on the dash turning off. It did come back after about 10-15 minutes. I had to pull over to the side of the road in the meantime. I brought my car in and no problem was found. I was told that there was no way they could order a $6,000 part if they could not reproduce the problem. I still have had this problem periodically, but it does not last as long. This can be a safety risk when the screen goes out when driving. My check engine light has gone off many time in the 3 yrs and 7 months of me owning the vehicle. I am asked if the light is blinking when this occurs. If I said 'no', I was told 'then you don't have to worry'. I had my car in to evaluate the engine light on, and was told not to worry that no code showed up (I did not get a service record if they didn't find any thing, despite me asking). The very next day I was stranded on a busy hwy. My car was towed to the shop. I barely got off the hwy as one of my fuel injectors was bad. I was 45 min from my home and the check engine light went on. I started driving home and called the service dept. I was told that as long as the light was not blinking, it would be ok, and I tomorrow I should call for an appt if it is still on. My car started to act up when I was nearing my home, but it was drivable. The next morning the light was still on. I did not feel safe driving it around and felt it was another fuel injector. I was driving my car to the shop and the car was slowing down a little at a time. By the time I was about 1/2 mile from the shop, my car was only going 14 miles per hour. I was driving on the side of the hwy with my flashing lights on. Very unsafe. I know that I have a lemon for a car, but not taken seriously, that is a problem. I have had many more times that my engine light was on and would bring it in for an evaluation. Sometimes things were found, other times not. I am concerned about that lack of concern.

Driving on freeway and noticed smoke. Realized I needed to pull over and brakes weren’t working. Off ramp was at an incline so car came to a stop just in time to get toddler and myself out of vehicle. Car was on fire.

I am reporting a serious and recurring safety defect with my 2023 Hyundai Santa Fe hybrid, purchased new in January 2024. The vehicle has suffered from over 30–40 sudden hybrid system failures, including loss of acceleration, “stop vehicle” warnings, and check engine lights. These incidents happen without warning, including while driving at legal speeds (40–70 mph), on residential streets and highways. Most recently, the car failed twice in two days, while my teenage son was driving within all road laws, including once with a friend in the car. The vehicle simply stopped accelerating in the middle of traffic, endangering them and everyone around them. These failures have happened at legal speeds ranging from 40–70 mph, on both residential roads and highways. There is no advance warning, just abrupt loss of power and sudden warning messages. We’ve taken the vehicle to the south charlotte Hyundai dealership multiple times. Each time, they either reset the check engine light or replaced indicators: but never addressed the root hybrid system failure. We filed a lemon law case, and Hyundai responded with only a $2,000 offer including legal fees, requiring us to keep the dangerous vehicle. We rejected the offer. These failures have occurred with children and passengers in the car. We have documented as many incidents as we could, including photos, service records, and communication with Hyundai. The vehicle is available for inspection upon request. I no longer feel safe driving or allowing my family to drive this car. This is a critical hybrid system failure that continues to place lives at risk. I believe this may be part of a wider pattern affecting Hyundai hybrid vehicles, and I am pleading with the NHTSA to open an investigation before someone is seriously injured or worse.

Vehicle failed to accelerate while operating on the highway. Pulled over and shut vehicle off and smelled gas. Vehicle would not stay started. Towed to dealer and was told it was a defective fuel injector. All injectors were replaced. Apparently this is a known problem. This could have been extremely dangerous if I wasn’t able to pull over. Hyundai should issue a recall to replace these defective parts.

The oil pressure switch has a faulty seal causing oil to leak out onto the engine block. This causes oil on the underbody and ground, smoke amd smell from oil on got surfaces, knocking noises from the engine, reduced power or hesitation, illumination or the check engine light and oil pressure light, high speed stall, and will also cause fire in the engine compartment resulting in death or sever injury. I have taken my car to the red mccombs Hyundai dealership in san antonio TX for repair and they have confirmed that it is the oil pressure switch seal that failed. The oil leak has also damaged electrical components causing a malfunction in the dash cluster and steering wheel control.

My engine seized at approximately 80mph on the interstate [xxx] ). The engine light came on only after I lost power. I only avoided a multiple car accident due to quick reaction and taking an exit ramp. Police came to my stalled vehicle and helped my push it off a major road to a nearby parking lot.

A few days before the complete engine failure the car became very jerky on the throttle response I would slowly add throttle and the car would jump all over the place with rpms and felt extremely jerky when shifting gears. At one point the engine downshifted past redline when decelerating off the highway. The day of the engine failure I was accelerating up hill after leaving a stop sign. Around 25 mph the throttle stopped responding and the engine went to idle around 800 rpm. The car started violently shaking and sounding like it was running on 3 cylinders. I tried the throttle again and nothing happened. At this time I was slowing to a stop on the hill while still in lane being unable to get out of lane to the shoulder. Upon coming to a stop the vehicle continued to shake and eventually the engine stalled while keeping the electric on. At this point there was never any lights on the dash board to indicate a fault. Upon attempting to restart the engine it turned over 3 times and eventually started all while violating shaking and eventually stalling again. The third time attempting to start it did not turn over. At this point I was stuck in lane and needed to call the police to come and assist me because I was unable to move the vehicle under its own power putting my life in danger. Upon taking getting it towed to a dealership they said it was a fuel injector fault.

At 22000 miles wheel speed sensor went out, all control system shut down and car became unstable. At 44000 miles fuel injector went out, was driving on freeway and car started shaking and losing power, then in parking lot would not start at all, had to be towed to dealer. This is way to many breakdowns for a car with such low mileage.

Was traveling on [xxx] near reston, va when the Santa Fe engine started missing and losing power and check engine light came on. Vehicle was towed to dealer and repaired on 04/26/24 mileage was 36285. The repair order says it was fuel injector for cylinder #1. The second time the same thing happened was on [xxx] near haymarket, va. The date was [xxx], mileage was 36577. The engine started missing lost power and check engine light came on. Vehicle taken to dealer for repaired. They replaced injector #2. The third time was about [xxx] mileage about 51000. Was traveling near haymarket, va. Engine started to miss, decrease in power, check engine light came on. Vehicle was towed to dealer. Inspection of the engine revealed injector #3 was malfunctioning and they needed to replace it but could not get the injector for it from Hyundai. The vehicle has been setting at the dealer since then with no idea when it will be repaired. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

Q: what component or system failed or malfunctioned, and is it available for inspection upon request? a: two fuel injectors on bank 2 are failing intermittently causing the engine light to flash and stay on (p0300 errors) and the car loses power.   q: how was your safety or the safety of others put at risk? a: driving to newark airport on [xxx] the car suddenly lost power and was quickly coming to a halt. Luckily I was was in the middle lane and was able to get to the shoulder without incident. This also happened to my daughter when she was in wa state, driving to work on the highway (the car was serviced but the fuel injectors were not replaced - see attached receipt). Q: has the problem been reproduced or confirmed by a dealer or independent service center? a: yes. An independent service center performed a injector value load test which determines the amount of blocked pressure the injector is performing under load. The values and the math show that more than 1 injector on bank 2 are failing. Q: has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? a: I had the vehicle in the Hyundai dealer but they did not do the injector load test and only wanted to replace all the coil packs and plugs. I had two other independent service facilities confirm the issue is with fault fuel injectors. Hyundai has the parts on hold and is not releasing any due to this issue. I do not understand how this is not a recall circumstance. I am fortunate that in both instances an accident did not occur. Q: were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? a: yes, the engine light comes on - at first blinking, then steady. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

Driving vehicle at highway speed, engine rpms dropped to less than 1500, could not maintain any speed, cel illuminated. As soon as vehicle was pull to side of road, it would no longer run. It would start, idle roughly then stall out. Vehicle was towed to mountain Hyundai in denver. High pressure fuel pump failed, fuel pump in one cylinder failed, fuel was dumped into oil fouling all spark plugs. This is the second high pressure fuel pump failure on this vehicle.

Vehicle failed an oil consumption test. Dealership acknowledges that the vehicle burns 1. 5 quarts per 1 thousand miles. The dealership initially told me that Hyundai would cover a combustion cleaning. However after acknowledging my mileage, they are now refusing to provide any assistance. This is a known issue and they are not acknowledging it. The dealership instructs me to drive until the problem progresses, but according to their data there is already a problem outside of the manufacturers specifications.

Per franklin county fire department report, they determined a malfunction in the canister vent valve associated with the gas tank initiated a fire. According to the department findings, the canister vent valve detached from the vehicle and was discovered approximately 200 yards behind the final position of the vehicle, still burning. This malfunction is believed to have compromised the fuel system, leading to an ignition and subsequent vehicle fire. The vehicle sustained extensive damage and was deemed a total loss.

I am writing to formally report an issue with my vehicle that I believe may warrant a recall investigation. The issue involves the fuel door, which is failing to open after the car has been turned off. This has occurred repeatedly and is preventing me from refueling the vehicle, posing a significant inconvenience and potential safety concern. Despite ensuring that the vehicle is unlocked and powered down as instructed, the fuel door remains stuck and will not release. This malfunction requires manual intervention or technical assistance each time I need to access the fuel tank, which is not only frustrating but could also become hazardous in certain situations. I would appreciate it if this matter could be reviewed for possible recall consideration or guidance on next steps. Please let me know if additional documentation, including my VIN or service history, is needed.

The car started jerking and the check engine light came on. I had to have it towed to my house. We can't get the car to do anything now. We get it started for 5 seconds, the engine completely dies.

Steering made clicking sounds when turning. Injectors caused the car to run very rough!.

The act is consuming all the engine oil only after 500-700 miles. It has been recored and tested at town hyudnia dealership in danville, NJ after it failed 2 engine oil composition tests but the dealership did not replace the engine nor put in a. Request to corporate Hyundai to replace the engine as it should be covered by the 2. 4l engine lawsuit a fe years ago.

Was going down the highway at 65 when my vehicle completely lost the accelerating component. Almost got rear ended so I pulled off. Then made it to work when it happened again. The engine light came on and gave 2 codes. Finally got it towed to the dealership where they have decided it’s either a new timing chain or new engine due to mechanical loss. They discovered there was no oil in the car and they have also found metal shavings in my oil. Now they are telling me I need a whole new engine. I only have 124000 miles on this car. The car was driving perfectly fine the day before and had just been to the dealer and looked over 1,500 miles before and I was told everything was perfect working condition. I am out $4000 on a car I bought a year and a half ago in October 2023. Was told my warranty only lasted a year.

>>>>what component or system failed or malfunctioned, and is it available for inspection upon request? according to the Hyundai bluelink app, the problem is caused by the battery management system, producing error code p0aa600. The result is that the vehicle does not get power to the wheels for a few seconds after giving it gas. It looks like the car is not moving, then it very slowly gains speed, followed by sudden acceleration. It is available for inspection upon request. >>>>how was your safety or the safety of others put at risk? it is a safety issue because other vehicles on the road may not be able to stop in time when the car pauses unexpectedly. Also the driver cannot predict when the car will surge forward. Merging or crossing traffic is very dangerous. >>>>has the problem been reproduced or confirmed by a dealer or independent service center? the vehicle has been to the dealership two times to be inspected for this problem. They state that they cannot duplicate the issue but of course they can see the error code in the vehicle history. It is an issue that occurs at random; not every time the car is driven. It has occurred a total of 9 times during the 2,872 miles we have driven since we purchased it. >>>>has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? only the dealer has inspected the vehicle. Police, insurance, or others have not been involved. >>>>were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? there is no warning that the error is going to occur. There is a warning when it is occurring, and the check engine light comes on. We purchased the car as new when it had 6,934 miles on it. It had been used as a demonstration car for the dealership. The error first occurred at about 7500 miles.

I purchased a 2023 Hyundai Santa Fe hybrid in November of 2023. Within a couple of months of purchase I had 2 incidents where without warning the car lost power and made a noise sounding like some sort of fan. One of the incidents was on [xxx] in massachusetts, the heavy traffic cleared, I was in the fast lane, and the car would barely move. It was a safety issue as there was no place to go on the left side of the highway and traffic to my right had already picked up speed. After a minute or so the power again became available. This has happened to me several times but Hyundai has told me there is no record of this happening with my car model. On occasion I have my grandkids in the car and I am very concerned that Hyundai will not acknowledge this problem. By the way, it happened again this morning as I was pulling away from a starbucks drive-up window. Can something be done about this? Hyundai should have records of my complaints as I visited the dealership where I bought the care and conversed via email with one of their service representatives that I do have a record of.

3rd time having the same engine issue where the fuel injector keeps going out. Once in February then again in April now again in Jan. The car shakes violently and unsafe to drive even when at a standstill.

The car has been consuming all the engine only after 700 miles. This has been a constant issue since December 2024 and the issue has been brought up with Hyundai dealership in denville, NJ and Hyundai corporate as well. Hyundai dealership in denville, NJ performed 2 oil consumption tests, which the vehicle failed both test only after 700 miles as it consumed all the engine oil. They refused to do further investigation or recall the engine as it should be covered under Hyundai txxi warranty given the Hyundai engine ii class action settlement a few years ago. The vehicle has broken down on me on the highway a few times and has put my family at risk and danger due to the negligence of the Hyundai dealership in denville, NJ and Hyundai corporate refuel to resolve the issue. Now the car does not start at all some days thus it has impacted my work and my ability to provide for my family.

Headed to my work ,outside temp 26 deg f, when on hiway entrance ramp, vehicle lost all acceleration. Vehicle is a hybrid, condition no warning lights on dash, vehicle was stuck in ev mode, which the ice engine would not start to help as normally would do. Hybrid battery began draining very quickly. There was a semi truck right behind me accelerating hard to get on highway . This time I managed to pull over on the debris filled shoulder before the system fully shut down as it has done before with the warning ?? hybrid system failure, pull over now ! and loud alarm going off. This is a serious loss of total motive power, which I've reported to Hyundai corporate, and dealerships for repair before, to which they say " we can't duplicate, all systems are fine", and blame me for the problem. Hyundai has washed their hands of this dangerous situation and won't help me. This is the 5th occasion of this problem, I now know from my experience and reading Hyundai forums this issue is wide spread among Hyundai tucson and Santa Fe hybrids, with some places replacing parts, that doesn't fix the issue. I know how to react by pulling over immediately, shut off the vehicle completely, wait. . . Then restart the vehicle, and so far ,it will drive normal with no codes or warnings after that, until the next random occasion it happens. This is extremely dangerous in cold weather and around other traffic posing a major collision hazard and stranding someone who knows less about this condition. Hundreds have reported this as per the forums, yet no recall or TSB or real fix has been issued by Hyundai.

1. Abs module stopped working. Car no longer has abs. Will not cover under warranty due to computer component. 2. Engine burns oil. 3 quarts in 1k miles. Combustion cleaning done. Now engine light is one, oil light comes on, car smells of gas & oil.

Our car had 2149 miles on it. Engine started to stalled on [xxx] on [xxx] from okc to tulsa. We made it to tulsa. The car was towed to tulsa Hyundai dealership on 12/25/2024. After diagnostic on 12/26/24, we were told the car had bad gas. The dealership performed the necessary work including replacing 4 fuel injectors in order to fix the problem. It cost $3991. 52 and it took a week. We were told since this was not a manufacturer problem that we are responsible for the repair. We paid for the repair. We always get our gas from costco. So we filed a report with costco stating that we got bad gas from them. Costco turned it into their adjuster at gallagher bassett. He investigated and told us that his findings indicated that costco did not have bad gas in the month of December according to their quality reports. No other cars filed complaints regarding gas issue. Our claim was denied. The question remained where the bad gas came from. Was it truly a bad gas problem or did the car have fuel injector issues and that bad gas was a cover up. We bought a new car, we purchase gas from a reputable company and we ended up with this problem that we were responsible for through no fault of our own. We are filing a report to see whether there are other cars of this model that had similar issues. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

Unknown car was purchased in September started having engine problem in December.

First- it has been reported to dealer at least twice when car was in for other service. They said they could not reproduce. When speeding back up from a stop on near stop, especially in a right turn, the engine will not accelerate. After a second or two it finally takes off. During this time, I fear getting hit by another vehicle, either from behind or to the side. It is very scary and puts me and my passengers at great risk! there was no warning indication at all. The date mentioned was the most recent time, but the issue has been happening since the car was brand new. Again, no help from the dealer.

Upon acceleration from a stopped or rolling stop the vehicle hesitates to propel causing a dangerous situation when entering traffic. Dealer claims its not bad and that the manufacturer is only going to suggest fuel injector cleaner. Fuel injector clener was tried with no improvement. Upon research I have found this to be a common problem with this model. This is not the first problem we have had related to this system. Programming has been adjusted in the past to fix another problem which tells me this could be a computer problem.

I am afraid of getting myself or someone else killed because there is a 1-2 second lag after stepping on the gas pedal after coming to a stop. This is extremely dangerous. My street empties onto a county road with a blind curve. I have had several instances when the delay between the car moving after I’ve stepped on the gas has lead to oncoming cars needing to slam on their brakes to avoid hitting me. I even called the county and asked that they put up a “dangerous curve sign. They put up a squiggly arrow instead which has not helped. My previous gas vehicles made this turn safely for 20 years. My nephew told me it’s a new feature in cars called “stop and gol meant to save gas. I think saving my life is more important than saving a little bit of gas. It happens all the time so I will put todays date in the space below.

Twice, the car refused to switch from ev mode back to gas mode. This resulted in the hybrid battery dying and the car losing power. The first time, I was merging onto the freeway and the gas pedal was all the way at the floor, but I was only maintaining speed (not accelerating). Both times, the car was driveable for approximately one mile on the hybrid battery alone. However, a warning came on the dash, “check hybrid system. Stop safely. ” the second time, I was able to pull into a parking lot before the hybrid battery died. The next day, I was able to drive the car normally. The dealership is unable to pull any codes or replicate the issue. Unfortunately, it only happens intermittently and we have not identified a common theme for the failure.

When I first start my car for the day, I get an error message, which says transmission error get transmission checked immediately. I’m unable to put my car into gear and when I try to go forward the transmission acts as if insufficient transmission fluid and does not accelerate properly and go into gear. I went to a Hyundai dealer in October 2024!to get the car serviced. The Hyundai dealer flushed the transmission system for a while I no longer got the transmission error message on the dash. A few weeks later I had the transmission error again and the car would not go into gear. I took the car in for a second time to be serviced by Hyundai dealer they said that they reset the software. About a week later I got the transmission error message again, along with the difficulty of engage in the transmission. The workaround I had for this was to turn the car off and turn it back on again and that would get rid of the transmission error message until the next day. I plan to take my car in to a Hyundai dealer this week and report to them that I’ve been having this transmission error message almost daily for the last week. This problem makes the car feel unreliable, and it is a potential safety risk to not be able to accelerate and change gear when operating the vehicle. The car also lurches foreard slightly after parking and turning off thr ignition.
