2026 Hyundai Santa Fe Hybrid problems

Filed Oct 22, 2026 · Driver assistance · PA

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.

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 by putting me back on the road without a proper diagnostic. A simple Google search shows that this is a problem with other vehicles of this make and model. I was told it wasn't their job to Google problems. It's only a matter of time before this serious defect kills someone with less luck and driving skill. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

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 at the time of this report, no diagnosis has been provided. The reported braking behavior was reproduced by the tow truck driver; dealer confirmation is pending. The vehicle is at the dealership for inspection. The exact cause remains UNKNOWN. The abnormal stopping response and unpredictable low-speed movement pose a risk of collision or injury, especially if they recur in traffic.

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.

My digital instrument cluster is intermittently going black and displaying 'Lost Signal' while driving. I took the vehicle in a month ago and they stated they could not replicate and this was not a known problem, that I would need to record the issue in a video.

SUPPLEMENTAL FILING to the federal safety agency Complaint No. 11768270 (filed 2026-10-01 for this same vehicle, covering steering/suspension defects). This new complaint covers ONE separate, newly discovered defect only: the rear-view (back-up) camera shows NO image. On 2026-10-02 (defect discovered and photographed), shifting into Reverse produces only a solid green rectangle on the center display plus the text warning "Check surroundings for your safety." -- no camera image appears at all. The rear-view camera is completely non-functional, causing a total loss of rear visibility while reversing, a safety hazard under the rear visibility safety requirement (FMVSS 111). No crash, no fire, no injuries, and no warning lamps illuminated. Vehicle purchased new on 2026-09-14. The selling dealer previously refused to inspect or repair this defect.

There is a safety risk on the 2nd row seats crushing a child. In my 2026 Hyundai Santa Fe Hybrid (Calligraphy trim), I've had two incidents where a child in the 3rd row pressed the button in the trunk to close the 2nd row captain's chair seats, crushing a child that was in the seat. These seats are not supposed to fold down when occupied. When the vehicle is moving, or not in park, or the seat belt is engaged, the seats correctly do not fold when the folding button on the top of the seat is pushed. The same holds true when the folding button is engaged from the 3rd row/trunk, EXCEPT the seat will STILL fold while the car is in Park and the seatbelts are engaged. I believe this is a design or software flaw, as clearly the seat should not fold while a passenger is in the seat. This presents a clear safety risk as a child can not provide enough resistance to stop the seat from folding, leading to a risk of injury or death - evidenced by the March 2026 incident that killed a [XXX] in the similarly-designed Hyundai Palisade. A recall and stop-sale was issued for the Palisade but one was not issued for the Santa Fe. A video of a demonstration of this situation and resulting safety hazard is available here: [XXX] The notes from my Hyundai dealer service visit are also attached. The service technician confirmed the problem is not on my car specifically, but is an issue facing all cars of this type. The service technicians and manager also acknowledged the clear safety issue and in fact encouraged me to make an the federal safety agency safety complaint.

I was driving the hybrid vehicle uphill on a highway and there was traffic so we were driving under 5 mph for about 20 minutes. When speed picked up I went to accelerate and the vehicle, it never accelerated when I depressed the gas pedal, and stayed in electrical mode rather than switching over to gas. The vehicle then shut off in traffic and I could not pull over safely on congested two lane interstate 17 and I was afraid as vehicles were swerving and driving past and we could not get out safely. The "check hybrid system, Stop safely" warning came on the dash. This vehicle at the time only had 8,808 miles on it and is relatively new. I brought the vehicle in to the dealership but they said "tech scanned for codes. No DTC present. No warnings on cluster at this time. Tech checked for ECM SW upgrades. None available. Tech Road tested vehicle without any issue. No repair performed at this time." When I picked up my vehicle they only put that only the check hybrid warning light came on and left off their report that my vehicle completely stopped working.
