2022 Hyundai Santa Fe: check engine light

Filed Nov 5, 2026 · Electrical · KS

I have had my Santa Fe SEL 2022 in the Hyundai service shop 3 times for the reoccurring "Shifter System Malfunction" warning. I have investigated this issue on the internet and found the federal safety agency reports this affects models equipped with the push-button "shift-by-wire" systems. Hyundai has acknowledged this issue with the TSB 23-AT-006H-2. However my vehicle continues to have this intermittent issue and the problem is never fixed. This electrical/mechanical issue poses a severe hazard to my safety as well as makes the car crippling and inoperable. My Santa Fe is unreliable to drive. I never know when I will get stuck somewhere and be stranded. No car owner should experience anxiety every time they drive because they fear the "Shifter Malfunction" warning will appear and make the car inoperable to drive. Then as of late in Oct 2026, I had another malfunction with my car that it went into limp mode and can't accelerate much higher than 25 mph and had to get my car towed to Hyundai Svc center. Could this be related to my reoccurring issue? The 1st time of the SSM warning was on 5/20/25. I could not get my car out of park. Shop found code in car related to SSM warning but it was operating normal for them. 2nd time of SSM warning on 6/30/26. I was stranded and called a friend for help. We had to disconnect battery for 15 min then turn car back on. Was able to take car out of park and drove to Hyundai service. It still had the engine warning light on did but techs said it did not show any codes. Shop had opening not until 7/14/26. Had my car for 7 days. I had to tell them of the TSB on the issue. They said they found issue with my wiring harness and replaced part. I thought my issue with the SSM was solved. IT WAS NOT SOLVED. For the 3rd time on 8/15/26, I once again got on my dashboard the "Shifter System Malfunction Service Immediately" warning. This was only a month and half from when the shop supposedly fixed the problem. They could not duplicate problem so no fix.

On June 20 2026 at 2:07pm Central Time there was a check engine light displayed on the dash of my vehicle 2022 Hyundai Santa Fe Calligraphy, while it was parked in the garage of my home and was just powered up. I had then performed the vehicle diagnostics test (pictures attached) that showed that there was an issue with the 'Transmission Control System' with detail that a full system check is recommended and to schedule an appointment with a dealer. I had later proceeded to contact local dealer 'Huffines Hyundai McKinney' for service as I was due for an oil change anyway. As I was driving the vehicle from my home which was about 13 miles away from the dealership, I noticed that the vehicle had great trouble shifting from 1st gear to higher gears, that the speed would be 20mph or lower no matter how much the accelerator was pushed and I had to drive very carefully in traffic due to the low speeds. I was told at the dealership by 3pm that day that there were no active recalls on my vehicle, that the transmission related recall that was showing up on google search for that DCT code wasn't specific enough to my vehicle and to book an appointment for vehicle diagnostics and transmission repair/replacement at full cost to myself. The multi-point inspection report after oil change showed nothing about the check engine light issue or that the issue was even diagnosed by the dealership. From that day until today Aug 29 2026, I've noticed that the vehicle still has trouble shifting from the 1st gear, that the vehicle drives normally when increased time is allowed between power up and start of drive (~2min of engine running idle) and that the check engine light reappears after a trip of quick power up and drive. There was atleast one instance where I had to pullover onto the shoulder to avoid high speed traffic while driving in the right lane.

At approximately 67,000 miles, the vehicle experienced a sudden vibration when accelerate and decelerate. Engine light was on and vehicle had a hard time to maintain speed above 40mph. Cars were honking behind us due to the lack of speed on road. It happen all of a sudden and cause me and my wife panic at first. The car was took to the closest dealer ([XXX] Hyundai [XXX]) and they found the problem was due to an internally leaking fuel injector, requiring a complete out-of-pocket replacement. This is a known, widespread manufacturing defect directly addressed by Hyundai Technical Service Bulletin TSB #25-FL-001H (which supersedes 23-FL-002H-1). The bulletin explicitly states that 2021–2022 Hyundai Santa Fe 2.5L GDI engines suffer from premature internal fuel injector failure caused by internal filter breakage, forcing owners to pay out of pocket for a design flaw acknowledged internally by the manufacturer.

I have videos of these two incidents and others that I could not upload. While driving on the PA Turnpike at 4:25PM on 5/22/26 75 mph my accelerator pedal stopped responding, my front collision warning light, engine, EPB, and numerous other lights came on across my dashboard despite there being no contact with any object and my speed rapidly dropped. The front camera came on as if there was an object too close. I was in the middle lane. While I was trying to move to the shoulder there were tractor trailers behind me and to my right that began flashing their lights because my speed drastically dropped and was unable to safely stay with the flow of traffic in the heavy rain. While still in Drive car started changing through notices on my digital screen "Check Blind-Spot Safety system" "Check Forward Safety system" with the car crash icon, and "Check Driver Attention Warning (DAW) system." Then I began trying to press the accelerator pedal again and the car would not move at all but the tachometer was going to 2x1000rpm. When I turned the car off and turned it back on again the engine light was still on, but the accelerator pedal was responsive. About an hour later when the tow truck driver from AAA attempted to drive the car on to the flat bed the accelerator pedal was unresponsive again. This was at least the fifth time my vehicle had lost propulsion without warning. Every prior time Bowser Hyundai had different reasons for the failure, made a repair, and said it was safe to drive. Another incident occurred 4/7/2026 using cruise control at 84 mph when the car unexpectedly lost propulsion. The accelerator was again unresponsive, I was on the turnpike with two children in the vehicle. I steered towards the shoulder and the car slowed to a stop. After that incident, Bowser Hyundai replaced the transmission on the car. They notified me on June 18 that they believe they fixed the problem again but I don't feel the vehicle is safe for my family and worry it will be deadly

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.

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.

I took my vehicle in on 2/03/25 for a back up camera recall and to have my transmission checked due it not shifting correctly. I was called within two hours and told the transmission needed to be replaced. Weeks later they called and told me they had good news and bad news, the transmission was replaced, however it would not work. They replaced the transmission for the second time and had me pick up the vehicle on April 17th. I picked the car up and immediately went back in and told her it was not shifting right. They told me to drive it home and see how it did and they would have the service advisor reach out. On the way home, the car was at 5000RPM at 60mph. It was not shifting. The check engine light came on the next day. The car was taken back and I was told on April 21st the transmission needed to be replaced again. I was called on April 7th and told that there was a wire they needed to check that went from the transmission to the pcm and they were going to check it and see if that would fix it. That is 3 total transmissions that have been in this 2022 vehicle. The vehicle is unsafe to drive and Hyundai corporate is not doing anything to help.
