Engine died suddenly at various speeds and a beeping alarm was activated along with the Malfunction Indicator (Check Engine), Engine Oil Pressure, and Charging System warning lights on the instrument panel. The instrument panel also read, "Engine off! Shift to N, then start engine-??. The car must then be coasted off the road to safety. When the car was brought to a stop, the Parking Brake and Brake Fluid warning light was illuminated alongside the other warning lights on the instrument panel. The instrument panel also showed that the car was in Neutral; none of the gear shift buttons were operable. Pressing the start/stop engine button restarted the car, removed all alarms and warning lights, and the car operated normally until the next occurrence. This scenario occurred five times: 4.05.25, 4.15.25 (twice), 4.22.25, and 5.28.25. The odometer readings were 12,250, 12421 and 12,425, 12,454, and 12,976, respectively. I have videos or photos of the instrument panel for all events but the first one, frightened as I was by that initial experience. The car was taken to Hyundai of North Charleston (HONC) for analysis 3 times: 4.16.25, 04.22.25, and 5.29.25. On 4.16.2025 the service advisor told me that they found 2 diagnostic codes, one of which related to the front radar, so it was replaced. I picked the car up on 4.22.25 and drove less than 3 miles when the problem recurred. I immediately returned to HONC. On this visit the front upper camera was replaced. My car was at HONC for 3 weeks waiting on the part and completing the installation. The problem reoccurred on 5.28.25 and the car was taken to HONC on 5.29.25 for inspection. On 5.30.25 the service advisor told me they didn't find any diagnostic codes and could not replicate the problem. The advisor said I could leave the car at HONC or they could "release" to me. I picked the car up on 5.31.25. Afraid to drive the car now, its use has been limited to necessary local trips on roads that have pullover access.

On [XXX] I was on [XXX] in Houston, TX southbound in the Woodlands area when my vehicle warning light for overheating went on. I pulled over on [XXX] and contacted Vehicle Assistance and the vehicle was towed to my dealer, Northwest Houston Hyundai. There was damage to a tube in front of the radiator and a/c condenser. The damage to the tube was approximately 1/16 of an inch in diameter and supposedly was caused by debris entering through the front grille which is designed like a large egg carton. The dealer spokesperson informed me that they had seen many vehicles like mine (2023 Santa Fe) with the same type of damage. I have been trying to settle this with Hyundai but they feel it is normal road damage and that the wide open grille design that allows it is not their problem. I can't even get them to approve a third party screen to protect the engine radiator from further design. They will not answer the question as to whether or not installing this item will void the warranty or not. It's dangerous to break down on a manor highway in a manor city particularly for us senior citizens. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

On two separate occasions, I was a stop light in high traffic. I was unable to drive my vehicle when the light turn green because of ?no power. A message display prompting me to "shift to P or N to start engine." Unfortunately, that didn't work. I had to sit there for a few mins, signaling other motorists to go around me. Eventually, I had to restart my vehicle. I panicked because I felt unsafe as I was blocking traffic. I took my vehicle to the dealer and was told that there were no code ?after the diagnostic test but yet the technician told me the door on the driver side is not aligned and I need to take it to a mechanic. I never got any alert that my door is open so that diagnosis didn't make sense. I took my vehicle le to the mechanic to check the alignment of the door who in return told me that there was no issue with my alignment. I am scared to drive my vehicle because I don't want to cause an accident.

The purchase price was $35,800. As of today, I have paid a total of $24,590. The vehicle has a manufacturing defect that has significantly impacted its performance. The engine has been problematic, as it appears to be consuming oil, and it often fails to start on the first attempt, requiring me to press the button multiple times. The most concerning issue is that the car can unexpectedly shut off while I am driving. Additionally, there is an abnormal noise coming from the engine. I consider this situation serious, as it poses a significant risk to my safety. These symptoms appear on January 13/2025. I want to emphasize that I have completed all scheduled maintenance on time. I filled out reports regarding this issue, and I have attached two reports that confirm the vehicle is consuming 2 quarts of oil per 1,000 miles, vehicle is consuming oil due manufacturing defect. These reports were given to me by Safford Hyundai.

The car has shut down unexpectedly for at least six times while driving at roads and highways. When this happens, engine stalls and nothing works and all alarms and check lights turn on and activated. Driver has to pull the car to the roadside which cannot be imagined when in a highway with all cars driving at 65-70mpH and the car suddenly slows down to stop. The other problem is that when the car is turned off and on again, all alarm and faults go away, and it can be driven again! It clears all safety and alarm checks and lights and behaves like nothing has happened. Car was bought on June2023. The first incident happened on Aug2023 and the next one on Sep2023. The next incidents on Feb2024, Sep2024, Nov2024 and the most recent on March 2025. The car has taken to the Sport Durst Hyundai dealership (Durham, NC) after incidents, however dealership did not perform any repairs in first four times claiming they could not duplicate the incident! (service reports attached for 3) After the third incident, we opened a case with Hyundai company trying to invoke the Lemon law, but our request did not go through despite all evidence we provided. Shamefully, their final suggestion to us was to sell the car! This was around March/Apr 2024. (Final decision letter attached) On fifth time, the driver did not shut down the car and towed it to the dealership while leaving electrical system on. They checked the car and claimed they found the cause and changed a part from car claiming it has been fixed. This was on Nov.2024. At the time we did not notice but, apparently that was a lie to make us quiet. The last time (sixth time) the same incident happened on [XXX]. The car was towed to dealership and is left there. We do have all screenshots from engine failures, although the dealership tried to wipe the history at some point.

Automobile approached and stopped at stop sign. When accelerator pressed to continue, car remained in place, shuddering (as if transmission were slipping),and making significant noise. Car would not shift out of gear, nor move. Operator shut off car and then restarted car. Car started normally and was in park without shuddering. Expectations at busy intersection was that it was my turn to move and did not do so, creating doubt on what my car might do next. Traffic flow was briefly confused and some drivers honked and were unsure what they should do. This could have caused an accident with an impatient driver re-ending my car, or with others going through the intersection "out of turn" and unclear on my situation. No lights or other warnings were displayed before this incident. It has not re-ocurred. I brought into the dealer who had no other reports of this type of behavior.

While travelling at highway speed, attempted to accelerate to pass slow traffic. Rather than accelerating, the car hunted for a gear, and wouldn't shift properly. The car downshifted but engine would not go beyond 4000 RPM and speed remained the same. This has happened multiple times. By unexpectedly not accelerating, this created a risky situation by not allowing car to pass slower traffic as expected creating a potentially dangerous situation. (Video of one of the instances exists). No warning lamps, messages or symptoms occurred up to that point. Car was brought to dealer but since no codes were contained in the computer, they said there was no trouble found.

- Winter Garden, FL, USA

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.

Driving at a low speed and blind spot warning light comes on, then all warnings light up and car loses all power and goes into limp mode. Engine light stays on, but will start back up after it is shut off, open and shut car door and restart. Engine light stays on. Has happened to me three or four times. In the past, the engine light will eventually go off before I can get it to the dealership. Hyundai said they couldn-??t duplicate the problem last time it was taken in, so nothing could be done. Gives error code P063512 each time and says EMS which I assume means emissions.

Driving up steep hill to my mom-??s house car would not drive up, as it hesitated I pressed gas pedal to no avail. I turned off car, got out & nothing was blocking me. Turned car back on & accelerated, this time it went forward.

- Walnut, CA, USA

There is an extreme amount of hesitation/delay from when you depress the accelerator and when the vehicle accelerates. I have had multiple incidences (both from a complete stop and while already moving) where I depress the accelerator and there is a concerning amount of lag time before the vehicle initiates movement. This has almost led to multiple accidents. This defect happens in all drive modes. This issue appears to have gotten worse over the time we have owned the vehicle. We did not notice this issue earlier on. We bought the vehicle brand new in Dec. 23.

Several times lately of extended crank. Saturday evening, car had been parked for 4 hours, did remote start and had extended crank of about 2 seconds. Car ran for about 3 minutes before we left. We left home and hit main road, tried to accelerate and vehicle seemed to go into limp mode. Would keep cutting the fuel out if tried to accelerate even above 40 mph. No check engine light came on. Put in neutral, could not get above about 3500 rpm. Vehicle was in smart mode where decides which mode to be in (normal, fuel economy or sport), when would try to accelerate it would try to change to sport as it knew power was not there. Was on a 6 lane highway and could not get up to speed. Finally was able to pull to side of road, shut engine off, waited a few seconds, restarted and issue went away, still no check engine light. I have contacted my local dealer, they said they have seen on another vehicle, was not sure of outcome, having service manager call me. Lots of complaints online forums of similar issues.

- Bonita Springs, FL, USA

While merging into the highway at approximately 49 to 52 mph, acceleration was applied to merge into the highway between moving vehicles. The vehicle responded by greatly increasing the rpm but not applying the power to the wheels. The engine revved up with very little acceleration. After 5 to 8 seconds, the power was finally transferred to the wheels and the vehicle sped up. The vehicle behind me had to apply the brakes since I basically cut them off. This was the second incident of this type.

- Peoria, AZ, USA

Throttle randomly cuts off or hesitates. It has done it about 15 times Dealer says no problem found. There is a lot of reports on the internet of the same problem.
