2023 Hyundai Santa Fe: engine stalls while driving

Filed Sep 24, 2026 · MA

I bought my 2023 Hyundai Santa Fe at Auto Fair Hyundai in [XXX] in XXX new. This is my third Hyundai from this location over the years. I have always serviced it there ever since I bought it. ( oil changes, tire rotation etc.) Back in XXX while driving home from [XXX] to [XXX] on [XXX] I hit the brakes in the left hand lane, in traffic and my vehicle shut off and wouldn’t restart. Very scary luckily a young man helped push my car off the highway. I sat 5 minutes or so and it restarted. I was told to disable the start/ stop feature which I did. On XXX I went back to auto fair in [XXX] with my issue. I was told I needed a new battery there was corrosion $408. I had them clean the corrosion $95 and I’d bring the vehicle to my mechanic friend where my battery was tested and it was good. I was told to disable the start/stop feature. I went out XXX and forgot to disable the feature and I stalled at 4 way intersection. Stuck there people beeping, traffic backing up and drivers passing by running red lights very frustrated. Yesterday I called Auto Fair service department (on a recorded line) asking if this is an ongoing issue with this make/model. Is there a recall? I was told they haven’t heard about this issue at all and she said good luck. I have 5 year warranty and there is only 24,000 miles on my vehicle. I found a forum online with many others with Hyundais having this issue. This is an accident waiting to happen I’m also reporting it to Hyundai Corporate and Highway safety commission.

I was driving, and the SUV all of a sudden lost power. I was trying to press harder on the gas pedal to keep up with the traffic, but the SUV was stalling. The SUV would not move, and as I kept trying to press on the gas pedal, a roaring noise like something was trying to turn but the engine kept trying to move the car. It felt like something in the car was trying to move but something kept slipping. I had to turn the car off in the middle of the street and restart it before it would move. Cars were blowing their horns. This is a safety issue and a dangerous Problem. The SUV just did the same thing a few days ago. I am calling the dealer to see what is wrong. I brought this car new 2023. It is under 12,000 miles

Vehicle stalled while driving — unsafe loss of power. While driving at normal speed, the vehicle suddenly shut off without warning and the electrical system malfunctioned. I had to pull over and restart car. This created a dangerous situation and could have caused a collision. Prior to this incidenct, the vehicle had intermittent electrical issues during startup (flickering electronics). This is the first time the car has experienced during driving, and is now at the Hyundai dealership. The car has been reported as unsafe to drive. This appears similar to other Hyundai stalling/power loss issues and may indicate a developing safety defect. Requesting investigation.

Component/System Failure: The electronic throttle control system malfunctioned. The vehicle is reporting powertrain diagnostic trouble codes P2118 and P2101 through the Hyundai manufacturer mobile application (Bluelink), indicating an electronic throttle actuator / throttle control motor issue. The vehicle is available for inspection upon request. Safety Risk: This malfunction poses a safety risk because it can cause sudden loss of throttle response, reduced engine power (limp mode), or stalling while driving. Loss of throttle control increases the risk of a crash, especially in traffic or at intersections. Reproduction / Confirmation: The issue is ongoing. The check engine light remains illuminated and the fault codes continue to be displayed in the Hyundai mobile application. The problem has not yet been diagnosed by a dealership due to lack of immediate service availability. Inspections Performed: The vehicle has not yet been inspected by a Hyundai dealership or the manufacturer due to delayed service appointments. No inspections have been performed by police or insurance representatives. Warning Indicators / Symptoms: The check engine light illuminated and remains on. Diagnostic trouble codes P2118 and P2101 are displayed in the Hyundai mobile application. The warning light first appeared in late January 2026. Current Vehicle Condition: The vehicle is considered unsafe to drive due to the active electronic throttle control fault and risk of sudden loss of power.

Was driving at 10 MPH on highway car began to cut out run rough and produce an extremely pungent smell of gasoline.. then stalled.. vehicle serviced and low pressure fuel injector had a leak causing fuel to spill onto the vehicles starter causing it to fail as well.. both were replaced under warranty by dealer. Highly concerned about fuel leaking from injector system onto a hot engine and electrical components and the aerosolized fuel. Police advised not to start vehicle due to fuel leaking and smell.

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.
