2023 Hyundai Santa Fe: engine failure

Filed Mar 4, 2026 · Engine · TN

I am submitting this complaint regarding a safety-related incident involving my 2023 Hyundai Santa Fe on February 14, 2026. While driving, the vehicle suddenly began to overheat, creating an immediate safety hazard. I was close to my home and was able to return there safely, but once parked, I observed coolant leaking from the front of the vehicle. Due to the risk of further overheating or engine failure, the vehicle was not drivable and had to be towed to a local Hyundai dealership. At the time of the incident, the vehicle had fewer than 38,000 miles and was purchased brand new. Despite this, the dealership informed me that the repair would not be covered under warranty, claiming the radiator damage was caused by “road debris.” However, they did not provide any evidence of an impact, puncture, or external damage. The only documentation offered was a video showing coolant spewing from the radiator after a technician inserted an object into the grille. This video does not demonstrate any pre‑existing road damage or confirm that debris caused the failure. I requested proof of actual damage multiple times, including photographs or inspection notes showing an impact point, but none was provided. Without verifiable evidence of external damage, I am concerned that this may represent a premature component failure or a potential safety defect in the cooling system. The sudden overheating while driving, combined with the lack of substantiated cause, raises significant safety concerns for me and potentially for other owners of this model. Thank you for your attention to this matter.

Fuel injectors are bad. The car misfires, I smell gas, runs rough. They fixed one the second week of December 2025. I had the same symptoms when my light came on again on December 23,2025, they said they couldn’t find anything and gave me the car back. On January 3, my engine light came on again, I had warnings sent to my email and phone app about potential engine failures they said today ( 1/6/26) that it was another fuel injector and was told they would not replace the rest until they went out. When I asked them how safe I would be on an upcoming trip, I was told to just check the car every day before I go!

While driving the engine dropped to 10 mph and would not respond to the pedal inputs. It is available for inspection. Dropping to 10 mph in traffic on a roadway doing 70 mph or even 35 puts everyone on the roadway in danger. The problem was not reproduced but was comfirmed by the dealer who inspected and serviced it. There was no warning before it happened but the dash displayed many warnings and even sent out an email when the engine failed. This was the first of five times that it has happened.

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.

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.
