The fuel injectors have repeatedly failed. I am on my third replacement.
In November 2025, my 2022 Hyundai Santa Fe began to hesitate when accelerating and would almost "jerk" when I pressed the gas pedal. Soon after my check engine light came on and I made an appt to take it for the closest Hyundai dealership (as it's still under warranty 33k miles) upon running a check the dealership notified me that fuel injector 1 has misfired and will be replaced. I receive my vehicle back and not even 100 miles later my check engine light in on again and the same issues are arising. Back to the dealership to see now fuel injector 3 has misfired and there is an open TSB showing all 4 fuel injectors need replaced. My vehicle was finally returned to me in January 2026. It is now February 16, 2026 and my check engine light in on yet again. I've been given the run around from Hyundai corp about fixing this vehicle. Why is this acceptable treatment when a vehicle is under warranty ?.
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.
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.
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.
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.
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).
Steering made clicking sounds when turning. Injectors caused the car to run very rough!.
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.
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.
Vehicle was being driven at highway speeds and suddenly lost the ability to accelerate with a "check hybrid system" warning. After pulling to the side of the interstate, car was shut off and restarted and brought back up to 40 / 50 mph when the same issue occurred with a lack of ability to accelerate and a "check hybrid system" warning. The issue appears to be related to some portion of the hybrid drivetrain. Car was then towed but two mechanics (one independent and one Hyundai dealership) could not replicate the issue and the vehicle system did not store any codes or history of the incident. The safety of the driver was put at risk by lacking the ability to accelerate on a major interstate, leaving the driver stranded for two hours waiting on a tow truck on the side of a busy interstate with traffic moving at speeds up to 75 mph.
Power loss with no warning or errors - hybrid system frequently fails to start gasoline engine when needed, resulting in sudden power loss and limited to 35 mph without warning. Serious concern at intersections and on major roads.
On Monday nite returning Tuesday morning I was coming home from work and I noticed my engine light is on and car is not running properly. I had to drive slower than normal at 12:30 am I can usually drive the expressway but I am glad I didn’t . I live in detroit mi my employer which is amazon is located in romulus michigan so I took [xxx] to [xxx] that when I notice my automobile was not driving as usual so I pull over and I notice my check engine light was on so I restarted my car several and it still was on so I prayed and drove slow all the way home thank god I made safely my auto have 7100 miles on it I had one oil change the next one is due at 10,000 miles. So the next morning I was at dealership when it opened and met with the manager at lafountain Hyundai on telegraph in dearborn mi he tried to diagnose my car and showed but it didn’t work so he told me to take it to lafountain dealership in livonia I arrived and they told me their were backed for three weeks and couldn’t get a appt and when I do I will have to leave like everyone else and I saw all those cars mine just sitting so I ask the reception and she had no answer after I explain so I tried Hyundai corporate office no answer so I been read all the trouble shooting information but that wouldn’t help because is slipping so I came home and back on the internet and began reading other comment. I can’t leave my car I need to go to work how am going there buses do run out there and I don’t have any other transportation so my car will just until someone helps me thank you for excepting my complaint please help me I am losing money how can I pay for my car with no money.

Middle of may 2024 car begins to feel like it's shifting when accelerating and stopping. Nothing found by Hyundai service dept. Lakeland. On apx. [xxx] while driving stepped on gas pedal and felt no power. Kept pumping the pedal & car started jerking. Managed to get to light and get in left lane to turn into plaza honking horn. Car slid to a stop at entrance. On apx. [xxx] my husband was driving home and same thing happened. Managed to slide car into our driveway. Both times the car had to be towed to dealership. Two fuel injectors have been changed and when I asked them to change other two they said warranty would not allow. Worst case scenario is if this happens on the interstate traveling at 75 miles per hour. Not only could we be killed but others. Both times there was no warning lights or any other warning. The car just started jerking and lost power. It can very well cause a car to rear end us and a multiple car chain reaction hurting or worse killing others. I am filled with anxiety every time I take the car out for errands. I also saw a similar incident reported in the better business bureau here in tampa by another person. I reported my incident to Hyundai corporation by phone and email and asked the rep to reported it to her superiors to see if they could just please let the dealership replace my other two fuel injectors & I was told they could do nothing. The dealership has told me several times the injectors must fail before they can replace. Apparently, the cost of the injectors is more than someone's life.

I filled up my gas tank and the digital guage was on 266 miles. After I filled up, it was the exact same mileage on the dashboard. It did not move after putting in about 4-5 gallons of gas.
Was driving on the highway while it was in cruise control and on several occasions when trying to accelerate the vehicle would jerk aggressively and struggle to accelerate. It did this about 3 times on my way to my destination. Took it in and they said they couldn’t find anything wrong with it nor could they replicate the issue. No work was on done on it.
Loss of acceleration while driving. This has occurred multiple times (always while moving or actively driving). The first time we were driving up a significant hill and the car slowed, lost power and we had to pull over and coast back down the mountain to a repair center. The second time, I was on the freeway and lost acceleration causing me to pull off the road in median. The third time, I was at a stoplight and when the light turned green, I had almost no movement after edging into the intersection. Eventually, at about 5 mph, the car regained speed. The check light went on in the first event and the car was supposedly repaired at the second dealership by re-tensioning "pins". However, no lights or warnings went on for incident #2 or #3 that occurred after the earlier repair effort. The vehicle is currently at the dealership service center for it's 7th day of "unable to replicate the problem" after incident #3.
Three fuel injectors out of four have failed in a year’s time frame. Car shakes, stalls, hesitates, and is dangerous to drive. Waiting for fourth injector to fail.
The car has been taken to the dealer multiple times for not accelerating out of 1st gear when starting up, and also for shuddering at high speeds. We have been stranded, hundreds of miles from home on 2 occasions, first with less than 30,000 miles because the spark plugs needed to be replaced. And the second occasion, also hundreds of miles from home, because the car failed on the highway and limped into a dealership, where one of the fuel injectors was replaced at approx 50,000 miles. The mechanic at this dealership voiced his concerns that these were the original fuel injectors, he said he was aware of the problem, but was only permitted to replace one of the fuel injectors. The car continues to shudder at occasionally, and refuses to shift out of 1st gear at odd times. We have tried to get Hyundai to replace the fuel injectors, but they refuse. I would like this to be serve as a record of our problems so that others can be aware of a problem that exists with these cars. This is a safety issue, as if the car will not accelerate on a highway or crossing a road, it is possible to have an accident. Also, having the car fail on a remote highway is also a safety issue.
While driving home from work, the 2022 Hyundai Santa Fe hybrid vehicle's, hybrid battery began to discharge rapidly, the gasoline engine did not start to charge the system, within 1/4 mile the hybrid battery fully discharged, and the vehicle lost all acceleration , the dash warning " check hybrid system, stop safely " came on along with a loud audible warning beeping. I pulled off the road as soon as possiable. The vehicle would not accelerate, and the gasoline engine part would not start. Several other warning lights illuminated, including the 12v battery low warning. I turned the Santa Fe off, and called Hyundai roadside assistance. While on the phone with the assistant, as it was night time, I couldn't see to check the VIN number for her I turned on the interior lights, then continued talking to the assistant. I attempted to restart the vehicle , and it started the gasoline engine this time, we talked, and she suggested I see if the hybrid battery would now charge it's self, which it very slowly did up to 1/8 full, then I attempted to move the vehicle to a safer location , a gas station parking lot. I was able to drive the short 1/4 mile to the parking lot, but the vehicle had very little acceleration. Almost no power! at the parking lot I attempted to rev the engine to get more power to the hybrid battery, while waiting for a tow truck.
1/3/24 driving down road car began shaking, driving rough and wouldn't pick up speed. Check engine light came on with code p030400/powertrain/ems/odometer 46,056. Car towed to Hyundai in gainesville, GA. Tech found cylinder 4 misfire and cylinder 4 was replaced. 2/5/24 driving down highway and car began shaking, driving rough and wouldn't pick up speed ,again. Check engine light with code p030300/powertrain/ems/odometer 47,176. Car driven to Hyundai in gainesville, GA. Tech found cylinder 3 misfire and cylinder 3 was replaced. 2/14/24 driving down highway and check engine light came on. Car was running okay. Code p219cfo/powertrain/ems/odometer 47,315. Car was driven to Hyundai in gainesville, GA for diagnosis. Tech found cylinder 1 air-fuel ration imbalance, TSB 23-FL-002h-1 internal gdi injector leakage and parts were ordered. Replaced 2 fuel injectors, high pressure fuel pipe and 2 rail bolts.
Ref NHTSA tracking # 11557625 vehicle broke down again within 5k miles and 45 days of prior repair referenced in above case. Similar conditions, highway speed, bucking and vibrating, loss of speed control, no warning. Subsequent repair confirmed same issue (fuel injector) as original breakdown/repair and my initial notification to NHTSA.
On 11/20/23, car refusing to accelerate past 30 and not shifting thru the normal gear sequence engine revving up to 3000 rpms and hesitating to go past 35 or 40 mph auto start light is lit the entire time in bright amber on the dash of the car pressed the auto start button and it would not disengage.
Vehicle began to shake, buck and emit a grinding noise while traveling on highway resulting in loss of speed control and associated fear. Check engine light appeared simultaneously. No prior indication of a problem. Managed to limp to next exit via shoulder. Had car towed to dealer as warranty was still in effect. Problem was diagnosed as fuel injector failure and repaired. Learned it is a common, recurring issue with Hyundai 4 cylinder engine. Not unusual to have multiple failures per vehicle. Hyundai is only authorizing repair/replacement upon individual failures, not pre-emptive even though common and recurring. Confirmed this is a common, recurring issue across Hyundai via our local mechanic and internet info. Vehicle has now experienced a second failure and is being towed to dealer.
Vehicle check engine light came on while driving and vehicle began misfiring. Vehicle was in the shop and injector was found defective. Vehicle again had same issue but intermittently and wife would have to pull over and shut down the car to be able to drive it safely home. Dealership tried blaming bad gas which was purchased a mile from dealership. Within 50 miles vehicle began acting the exact same way and Hyundai dealership says injector needs replaced but blaming contamination not a known issue Hyundai has with injectors. Found multiple instances of same issue and same made up issue of contaminated gasoline even at the same dealership I went to. Faulty injectors make the vehicle unsafe when traveling at highway speeds on busy highways.
I was idling for 15 minutes and then drove for 10 minutes at which time the check hybrid system stop safely alert showed on my dashboard with the red light. I was on a bridge and could not stop in the middle, this was very terrifying and dangerous as I was loosing acceleration and speed and it felt like the car was about to totally turn off, I was losing control, I was pressing on the brake and I felt it was not braking at which I point luckily I was at the end of the bridge and pulled aside, and turned it off. I waited 15 minutes before turning it back on and drove it back home. As I was driving it I can see the battery level rising. I plugged the charger that night to charge it and it started charging but then suddenly stopped and would not charge. Since then I tried charging it again and it charges for an hour and stops. I took it the dealer at the earliest appointment I can get and they ran diagnostics and no code came up. They said that it had to do with the coolant and they put in a new coolant and that should hopefully solve the charging issue. I tried again to charge it at home and again it charged for an hour and then it stopped and will not charge again. I am scared to drive it far now and especially on brides.
2022 Hyundai Santa Fe hybrid. This incident has occurred twice at the time of this write up. Both incidents have happened on the first start up of the vehicle engine for the day in the early morning (on the way to work). The temperature outside was cool (10-35 degrees, maine). On at least one occasion it had rained during the night before using the vehicle. It may have been damp on the other occasion as well. After about 3 miles of driving the vehicle it completely loses power. No amount of movement to the accelerator changes the sudden loss of all power. This is a hybrid and the battery gauge below charge/economy/power rpm area of the vehicle starts to completely and instantaneously drain to what would be zero had I not been able to pull the vehicle over and turn the vehicle off. At this point, on both occasions, leaving the vehicle turned off for a minute and then restarting the vehicle seems to alleviate the problem. The incidents have occurred about 2 months apart and since the vehicle turned 20,000 miles. I also feel like it takes more push on the accelerator to get the same response that I got on day 1 when I drove it off of the lot at the dealership. I also notice that the ev indicator light does not come on as frequently as it used to. It would always come on when coasting - and now sometimes it does not.
I have experienced power loss soon after I bought the car in Dec 2021. While I was driving the car was going in a constant speed of 20 to 30 mph. However hard I pressed the gas, car felt not responsive. Reported this to the service center and was advised that this may be since car is learning my driving habit. Later in December 2022, received a recall 236 letter from Hyundai which was mentioning an issue similar to the one I experienced. Took the car for recall and informed me that the software upgrade is done as per manufacturer recommendations. Now on March 28th 2023 while I took the car out in the morning, there was more smoke than usual. And the same issue happened again. The car was not going beyond 20 to 30 mph for around 6 miles. Reported the same to the nearest service center and booked an appointment after 2 weeks . Also sent a complaint to Hyundai motors directly.
We have had already had two issues with our Hyundai Santa Fe that we purchased new from a dealer on 5/21. The first malfunction happened on 7/23. While driving, we had several messages come across the dashboard warning that some sensors were not working properly. We then had the warning light, front collision light, the traction control light, the abs light, the auto hold and the emergency brake all light on the dash. We also lost the blind spot sensor on the side mirrors. Called the dealer and took the car in. Two days later was told it was a wheel sensor and all should be good. Then on 8/31, while merging onto a highway, I pressed the accelerator and although the engine revved, the car did not increase in speed. Luckily the car behind me was able to swing around me and I put on my hazards and pulled to side of the road. I turned the car off, restarted it and pulled out. Five miles down the road, while in traffic, the same issue occurred, but after about thirty seconds or so, the car jerked and picked up speed, back to the dealer it goes and they called to tell me that they cannot replicate it and there are no diagnostic codes showing. They are going to keep it for a few more days to do some more diagnostic testing, but don't know what the issue is. This is a brand new car -.
Hybrid system failure while driving. Driving car, acceleration stopped dangerously, then dash warning prompt to stop driving immediately. Dealer was unable to diagnose and resolve.
My vehicle Hyundai santafe plugin hybrid 2022 is not showing an accurate gas miles range. It is giving incorrect information especially when traveling long drives. This is giving me anxiety about the loss of gas in the vehicle. It is also does not giving approximate mileage as described by the company on the sticker.
New vehicle purchased 10/15/21 form lester glen Hyundai in toms river NJ. After two weeks and 1100 miles car started leaking gasoline on garage floor, street and driveway at rate of approx one drop every two seconds. Called closest Hyundai dealer (burns Hyundai), both dealerships said appointments were three weeks out, scheduled on 12/1 with burns. Stated this was a hazerdous waste spill and extremem safety hazzard but dealers made no other offer of help. Before filing complaint called Hyundai corp and they told me they would escalate but would take 7 days to get back to me (Hyundai complaint #189991007). No one has called me. In last effort lm with president of lester glenn 11/18 at 3:20pm asking to call back and resolve so I would not have to file complaint, nobody called me as of 11/19 at 1pm. Leaking appears to be coming from a while plastic block at the rear of the gas tank.
