2023 HYUNDAI SANTA FE HYBRID Recalls, Complaints & Safety

Own a 2023 Hyundai Santa Fe Hybrid and have experienced the following issues over the past year and a half. Beginning after maybe 40,000 miles we pulled out onto a roadway and the engine immediately lost power and started flashing a glaring red warning that the hybrid system was failing and to pull over. We luckily were able to and turned the car off and waited. I tried to turn it on and it came back to life as if there was never an issue? We drove off. it left no warning code or did not update my Bluelink App. I took it to the dealership and they could not find any issues. Fast forward another 5 or 6 months and it happens again. Take it to the dealer and they keep it a week to go over it but still nothing. Within a week of getting it back it happens again and this time I am videoing it happening to me. Back to the dealer and provide the video because again the car did not log the event nor did it update my app. They hold it again for a week and try different things. They still cannot figure it out and I get it back.... it happens again.... This time the dealership was able to come up with an answer and that the oil level was too high. I got the car back and it seemed to work. Probably now 6 months go by and then this week I drive over to Jacksonville (5 hr drive) and visit. Again the car scares us on the highway and I have to pull over. Havea friend meet us with tools and we jack up the car and let out enough engine oil to insure we can read between the two marks on the dipstick. We drive off but the engine keeps hestitating and we almost make it back before it completly shuts down. We tow it to the Dealer in Jacksonville. They call the next morning like they can't find anything wrong! I explain everything and remind I don't tow cars for fun - something is wrong with the car and it is leaving us vulnerable and worst is it is not leaving any codes. Not sure but I have lost faith in Hyundai

One two separate occasions while driving the car has lost the ability to accelerate. There is no acceleration power even when completely flooring the gas pedal. The dash displays a red circle warming that states "Check Hybrid system. Stop Safely". I have had to coast to the side of the road and then the car shuts off. It has taken several minutes before it can start again, and then displays a warning "Park with engine On to charge battery" before being able to shift the car into drive. I immediately took the vehicle to the dealership at which I had purchased the car. They have run a diagnostic on it and did not find any error codes stored in the computer. I picked up the vehicle from them and immediately upon pulling out of their lot it happened again. After losing power, coasting to the side of the road, and waiting for the engine to be able to restart I took it immediately back to the dealership. They have had my car for 5 weeks and cannot diagnose the problem or offer any recommendations for repairs.

The vehicle will not accelerate and comes to a complete stop while driving. Within days, it displayed ‘Check Hybrid System. Stop safely’ and lost propulsion while driving.

On September 4, 2025 as I pulled on to Interstate I-70 my car suddenly lost power. Gas engine died. Loud attention sound started. Instrument cluster started flashing red with message "EV system failure, stop immediately" EV battery showed full depletion although a moment before it showed about 75% power. There was only enough propulsion to keep moving slowly. Since this was a construction zone the shoulder was blocked off and roadway was reduced to only one lane. I had no where to go. A large truck narrowly avoided rear ending me. I was scared and felt helpless. Eventually I was able to pull off and shut off the car. It was able to be re-started immediately with no warning indicators and EV battery power restored. This loss of power has happened 6 times before during the time I have owned the car. Last time was in March 2025. Each previous time it happened I was traveling at about 35 miles per hour and while annoying I did not fear for my life. On March 6, 2025 I had the dealer, McCarthy Hyundai, check out this problem. There were no detectable problems or problem codes. I was told that it might have been caused by the oil dip stick not being fully seated. It was obvious they had no clue what caused this but that I should come back if it happened again. I have reported this to Hyundai customer service who would not confirm that this was a problem encountered by many others. From looking at reports on the internet, my problem is not unique except for being life thretening. Customer service had me bring it back to dealer. Yesterday, September 24, I picked up the vehicle whohad it for a week to try to fix the problem. Once again there were no error codes. Only problem they found was an ignition coil which needed to be replaced. They could not give a convincing explaination of how a bad ignition coil could cause a complete failure of the gas motor and EV system or why if the coil was sole problem that it would only cause this failure every 3 to 6 months. Please help!

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.

We were driving in Montana down [XXX] and heard a very large “pop” sound above us. Our vehicle was traveling alone in the area at the time, no other vehicles were around ours. There was no debris on the road or flying in air at the time, either. At this point the panoramic roof glass was closed but the interior cloth cover was open and there was no evidence of any damage. When we stopped for gas, the front glass panel covering behind the windshield and before the panoramic roof glass, was completely shattered. The weather was the same as it had been, 80F with minimal cloud coverage. There was no sudden change in weather/driving conditions.

Between [XXX] am on [XXX]. I powered on my vehicle and the rear trunk door simultaneously opened. As I was driving my son to school that morning, I noticed water dripping onto my foot. I continued to drive but was distracted by beeping and warning messages but because the dashboard display was constantly switching from daytime to night lighting I could not readily see the dashboard. I tried to manually adjust the light by turning the knob off "auto" and also turning lights to "off" but it would immediately switch back. I made it to the first stop light and while stopped I was able to observe water droplets on the front panel of the interior fuse box. I pulled open the panel and water dropped out onto to floor. I replaced the panel. I continued to drive but was panicked and worried that water was in the fuse panel area. I arrived at my son's school and left the car running as he was dropped off. On the drive home, the beeping continued. This time, I saw the warning message about vehicle in my blind spot but I was on the street corner about to make a right turn and there was no vehicle next to me! The lights also kept switching as before. There was rust observed in the fuse panel area. When I got home, I called the dealership to inform them what happened. They refused to give me a loaner. I told them that water intrusion should not have occurred (we had severe weather and heavy rains the day prior) and now my car was having electrical issues and I was concerned for my safety and the safety of driving my 3 young children in car seats should there be an electrical fire. I mentioned the recall on my vehicle for water accumulation in the tow hitch and risk of electrical fire. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I am reporting an URGENT REQUEST IMMEDIATE ACTION REGARDING A SERIOUS UNRESOLVED, RECURRING PUBLIC SAFETY ISSUE WITH MY VEHICLE. IT IS POTENTIALLY THE FAULT OF ALEXANDRIA HYUNDAI'S SERVICE DEPARTMENT (in Alexandria, VA) WHO HAD JUST SERVICED MY VEHICLE FOR WHAT SHOULD HAVE BEEN A ROUTINE SERVICING (on May 7). My car had a catastrophic and complete failure on a high speed highway (the car quickly decelerated) which represented an incredibly danger situation for myself and other drivers on the road. My car was purchased in 2023 and has 15,241 miles. It has been perfectly maintained. On [XXX], I was returning to my home in Virginia from Maryland on an 8 lane highway with a 55mph speed limit when I had a very dangerous complete failure of my car. Simultaneously, the car started bucking back, the speed was decelerating regardless of my pressing the accelerator to keep my speed the same as traffic, and I received a flashing large red message that said "CHECK HYBRID SYSTEM - STOP SAFELY." Fortunately I was in the far right lane and was able to veer it over to a narrow shoulder. It was 8pm and getting dark. After a short while, the car lost all power so I was on a narrow shoulder with no lights flashing anymore. I was in this dark car with a lot of traffic speeding my with my 2 dogs. I became incredibly stressed about how we were going to get home. I contacted AAA, a police officer and Uber Pet who worked together in this unsafe situation on the side of the highway to get myself and my dogs home into the Uber vehicle with only the front door opening (no power). It was over 2 hours before I was home safely It was incredibly stressful situation. The car was towed to Alexandria Hyundai and they dismissed the issue and fixed nothing. I contacted Hyundai customer service and asked for escalation and they have done nothing. I am restricted in my driving because of the severe safety risk but had to drive again on [XXX] and it occurred again on a highway INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U

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.

The contact owned a 2023 Hyundai Santa Fe. The contact stated that his partner was driving at 50 MPH, a light ahead had just turned red, with two vehicles stopped just a couple of feet ahead of her, the contact stated that his partner had proceeded to frantically attempt to brake, however, the vehicle did not brake in time, and the automatic braking assist did not initiate. The complete front end of the vehicle was destroyed, as the vehicle crashed into the vehicle ahead. There was no property damage. The vehicle came to a stop after the crash. The driver's side air bags were deployed, however, the contact emphasized that it appeared the air bag had not fully deployed. The vehicle was towed to a lot. No warning lights had illuminated. A police report was filed. The vehicle was destroyed. The contact partner was injured, and she was seated in the driver's seat, and a single civilian seated in the driver's seat of the vehicle that was hit from behind was injured. The contact stated that his partner suffered injuries to her chest, and the other individual suffered injuries to the neck. Medical treatment was needed for both individuals. The local dealer was contacted however the vehicle was not diagnosed, as the vehicle was a total loss, and the manufacturer was not notified of the failure. The approximate failure mileage was 23,824.

Crash 2 injured

Santa Fe will randomly experience inability to accelerate. I will hit the gas pedal, the engine will rev all the way up to power, it will slowly crawl forward and than violently accelerate. From the time I hit the gas pedal to the time it actually starts moving takes several seconds. It does this every time I come to a stop once it starts. It has done this 4 occasions now. It puts me at significant danger trying to turn across traffic. In general, it not accelerating as you would expect is a very dangerous situation. Dealer has had the car for over a month and has had the car reproduce the issue. The HEV light and check engine light had come on a couple of the occurrences.

As my wife and I were traveling down the interstate at 45 mph, we heard a loud POP, but we were unable to figure out where it came from. Just a few seconds later, the sunroof exploded into a million tiny pieces of glass that partially rained down on our heads and shoulders. It was quite a startling sound. There was a hole about 8 inches across in the moveable sunroof and more pieces were continuing to fall out. To protect our heads, I closed the shade. There was no evidence of an object striking. Windows were all closed when the incident occurred.

Vehicle has gone into limp mode 2 times in the past week. Power when accelerating would not exceed 30 mph when pushing the gas pedal to the floor. Had to pull over as I was getting onto the highway and stop/ power down the car and restart.

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.

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.

I have pinging sound coming from the engine when I accelerate. Transmission seems to skip during acceleration. Took it to the dealership for repair since the car is under warranty. Dealership replaced a bearing in the axle and replaced the turbo. I’m still having the same issues. Dealership had my car for 5 weeks dealing with this issue. I feel they don’t know what’s causing the problem.

The Automatic Emergency Braking System, on multiple occasions now, has slammed on its brakes at highway speed when there are no obstacles, barriers, or even vehicles in sight ahead of my wife. This happened to me the other day also when exiting the highway onto an exit ramp when it "Detected Collision" when *nothing* was around me, no vehicles or barriers within any reasonable distance. It's going to end up causing someone to rear end me or her - absolutely unsafe and 100% putting my wife and child at risk. We're taking it to the dealership on Saturday and have verbally informed them of the issue. No warnings, no messages, no nothing prior to incident - the car is practically brand new.

Three times this has happened. The instances occurred on Highway 680 between Pleasanton and San Jose. I was going the speed limit - 65 miles per hour - as were tons of cars around me. Suddenly the car would brake, startling me because I was nowhere near another car. It frightened me a lot! I think it is the automatic braking system - either the front end collision warning or the blind spot collision warning. It could have easily resulted in an accident. I took it to the Hyundai dealership, and they knew they could not likely duplicate it. They showed me where to turn off the vehicle control (braking) for the front end collision warning and the blind spot collision warning. I have read on the Internet several other parties that have experienced this - car-controlled braking while traveling at high speed with lots of cars around.

See attached document for complaint.

Driving down interstate at 70 mph and car started to brake while foot on gas pedal. Would not go…red brake alert came on. Luckily no other car in left lane and pulled off to side of road. Car would not drive. Called tow truck.

It started in April 2024. After the dealership performed an oil change we heard a strange noise whenever we accelerated. The dealership said it was either the transmission or the hybrid motor and both were on back order (usually an indicator that these parts are in great demand). After several weeks both parts arrived but they only replaced the transmission because that took care of the noise. A few days after we got the car back, we heard a clunking sound whenever we shifted. I tried to take the car to a different dealership but they said we had to return to the place that installed the transmission because bolts were missing. We went back to that dealership and they said no bolts were missing but they did need to be tightened. After that the clunking stopped, however, the next day we started experiencing other problems. The check engine and master system lights came on and the car would hesitate when accelerating. This was extremely dangerous when we were on the freeway and/or trying to accelerate from a traffic signal. Also, it had trouble shifting into reverse. The dealership said the codes were indicating the hybrid system battery needed to be replaced. The car has less than 20k miles.

One of the 2 horns has stopped working. After checking the Hyundai Forum website, I've found that one or both horns has suddenly went dead on not just Santa Fe's, but virtually all Hyundai models across the board. This seems to be a widespread defect. This is very dangerous because the cessation of operation is sudden and without warning (ie, no dashboard warning light). If there is a need for the driver to sound a horn in a time of danger there may be absolutely no way to give a warning.

I was driving 70 MPH on highway and the AEB activated despite no other vehicles in front of me. Thankfully the car behind me was far enough behind that they could swerve out of the way, or it could have been a massive collision. Additionally the person behind me could have swerved into traffic Causing a massive accident. This is happened twice the other time I was going 50 miles an hour. I am afraid to drive this car on the highway now.

When I start driving the car if I come up to a hill when I try to accelerate to move forward the cars engine cuts out almost like it stalls. I have to floor or pump the gas which makes a revving sound and the car will go.

The contact owns a 2023 Hyundai Santa Fe. The contact stated while driving at approximately 30-35 MPH, the vehicle lost motive power. The contact restarted the vehicle and the vehicle worked as designed for several miles before the failure recurred. The contact stated that several unknown warning lights were illuminated. The vehicle was towed to the local dealer, where it was diagnosed and determined that the failure was due to the accelerator switch. The vehicle was repaired, but the failure recurred. The contact stated while driving 10 MPH in the driveway, the vehicle lost motive power. The manufacturer was not contacted. The failure mileage was approximately 6,800.

While driving the blind spot safety system, driver attention warning system, and lane following system malfunction at the same time, and the vehicle loses power steering. The first time this occured was in the parking lot of an elementary school in April 2024. I was driving less than 2mph and the vehicle had less than 8,000 miles on it. The dealer said they would be unable to diagnose unless they witnessed the errors. The second time it occured was in May 2024 while driving on the interstate at around 75mph. The vehicle was driven directly to the dealership who kept it for four weeks. They said the connections to the ECU were severely corroded, sanded them down, and added a water protectant. The third time it occured was a month later. The dealership has had the vehicle for two weeks with no diagnosis. Losing power steering suddenly while driving is incredibly dangerous, especially in a vehicle of this size and weight. It is difficult to control the vehicle without power steering, and in all cases there have been other vehicles/people in the area who could have been injured.
