2023 Hyundai Santa Fe

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 fifth of five times that it has happened so far.

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.
