2026 Hyundai Santa Fe Hybrid problems

“This is the SECOND occurrence in the past two weeks. I was traveling on a HEAVILY trafficked 10 lane divided interstate, doing the speed limit on cruise control when the vehicle suddenly and inexplicably lost power. It went into "limp mode" (will not go over 30 mph). Thankfully i was able to negotiate to the shoulder but the maneuver was EXTREMLY dangerous as the rest of traffic was moving between 60 and 80 mph. It was harrowing and extremely frightening. Warning lights that were displayed- First, a "Check hybrid system" message appears. Accompanied by SEVERAL other warning lights. Eventually, a "stop vehicle and check power supply" message appeared and would not even move in "limp mode". This appears to be either a bent connection plug or fuel injector issue. The first time this happened ([XXX]) it was towed to Southern States in Raleigh, NC (I purchased it from Johnson in Apex) where they concluded nothing was wrong. They claimed no codes were available other than some low battery codes. This was a lie. The vehicle app showed two codes-POC7300 and P193700. They did nothing but recharge the battery by running the engine. I feel this dealership put me in danger…”

“Traveling the PA Turnpike with the cruise control on and traveling 73 mph. I was in the far left lane and just passed a slower car. There was nothing in front of me in the far left lane or the lane next for at least a half a mile. After just passing the slower car the forward collision avoidance came on and tried to stop the car. I put my foot on the brake as an instinctive action which I believe disengaged the Forward Collision Avoidance system. The dash board lit up saying it was the Forward Collision system. If there was another car/truck following me closely they would have hit our car and at that speed I am sure I would not be here writing this. Calling today the dealer to have this checked out. No one else has inspected or checked this problem yet.”

“Vehicle lost power and went into "limp mode" at highway speed on a busy interstate. I was able to get to the shoulder and "limp" to the next exit (would not exceed 30 mph) but I was lucky to be able to safely get there. The dealership said it was a battery issue? They acted like it was no big deal. To unexpectedly lose power at highway speed on a busy interstate was very frightening. (I had to negotiate several lanes to get on the shoulder). I also feel Hyundai is not taking it seriously. The dealership (Southern States) said no incidents came up in the computer scan and they just ran the engine for an hour to recharge the battery. Nothing makes sense here. About 15 minutes before the incident a warning came on the screen reading "there may be a problem with the engine management system". After trying to "limp" home, it completely died, requiring a tow to the dealership. Another warning "stop vehicle and check power supply" came on the screen followed by the dash lights going crazy like a pinball machine. This could have ended a lot worse.”

“1.Fuel did not activate on this hybrid while in stop and go traffic when apparently the battery died. There was plenty of gas in this brand new car. The entire car died, gas pedal inactive, on the freeway just when traffic opened up with red car/exclamation point indicator on dash. After power cycle car Its message said something like “pull over and charge car in park”. We were close to shoulder so were able to do as instructed. 2. Car died suddenly in freeway traffic w 4 passengers inside. Could have been rear ended. There was no information in manual, on line or through BlueLink app on the battery function, this particular message or the problem. Or criteria that causes car to fail without switching to fuel. 3. Days later when I could get an appointment, The Escondido Dealer did diagnostics, visual and test drive and found nothing. Dealer had no means to look back at history to ID fault codes at time of event. I had exact time/miles. They did not check battery as the diagnostics were clean. Complaint made w Hyundai consumer affairs. [XXX]. Case XXX. They could not tell me criteria or specifications for message to pull over. They could not direct me to battery…”

“On October 9, 2026, a 2026 Hyundai Santa Fe Hybrid Calligraphy with approximately 2,702 miles experienced abnormal braking and severe jerking/vibration while being driven at low speed in a parking lot. The brake pedal had to be pressed all the way down to bring the vehicle to a complete stop. The tow truck driver independently experienced the same braking behavior while handling the vehicle. Multiple warning indicators appeared simultaneously, including ABS, brake system, electronic stability control, and driver assistance warnings. Dashboard messages included “Check Forward Safety System” and “Check Driver Assistance System.” Due to the impaired braking and drivability, the vehicle was not driven further and was towed to an authorized Hyundai dealership. Hyundai Bluelink history shows recurring engine/powertrain trouble codes P011400 dating to July 25, 2026, and P011300 first recorded September 18, 2026. The vehicle previously underwent a dealership repair for a sensor-related issue, reportedly involving an improperly connected component. It is unknown whether that repair is related to this incident. The dealership has acknowledged receipt of the vehicle, but…”
