2022 HYUNDAI SANTA FE Fuel/propulsion System Problems

The fuel injectors have repeatedly failed. I am on my third replacement

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.

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.

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.

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.

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.

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.

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

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.

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 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 -
