2024 Hyundai Santa Fe: check engine light

Filed Jul 13, 2026 · Engine, Fuel system · IL

I was merging onto the highway and the acceleration stopped working and the vehicle would not go more than 25 mph. Had to restart car in shoulder, isue seemed to self correct but then it happened 10 minutes later stranding me in between the highway and exit ramp. This was a huge safety issue and myself and others lives were at risk. I am bringing the vehicle in for inspection but this seems to be a recurring hyundai issue. There were no warnings that came on. The auto mode on the dash went from green to an amber color. When i restarted the vehicle nothing changed. After the second time it occurred a check engine light came on.

I bought the 2024 Santa Fe XRT Pro new off the lot Sept. 2024. Brought it in for 3 different recalls but the electronic system panel is new: The panel lit up with every warning sign it can convey: from the engine light to the coffee break, to the emergency warnings. This has happened twice; once a few weeks ago and again a few days ago. My car is back at the dealership for repair to the electronic panel. The first time, the dealership replaced the entire panel as it is still under warranty. It's at the shop again and I don't know what they will do this time. I would trade it in, but the trade-in value sucks.

Vehicle was not driven for 2 days. The check engine light is one and says "active airflap issue" the flaps appear to be open when a/c is on and closed when vehicle is off. There is no debri or anything arount the air flaps. This could cause potential overheating and should not happen in a years time. We travel for my husband's job and this could be very dangerous. We thought we were buying a new RELIABLE vehicle.

I was driving and the car started to loose power and then the engine light came on and the car would not go. Everything happened at one time. The wrecker took the car to the dealer and the dealer confirmed the transmission went out. It is very dangerous for a new car to have the transmission fail while driving. This is a new car. The transmission failed and it is available for inspection at the dealer. The car is currently at the dealer and I am waiting to find out how long it will take to get a new power train.

When placed in "Park" the vehicle's brakes did not engage, which allowed the vehicle to roll backwards when I exited the vehicle. I was able to reproduce the problem again and I recorded a video showing the problem. When pressing "Park" on the electronic shifter, the dashboard displays that the video is in "Park". However, the brakes are not engaged as evidenced by the vehicle rolling backwards when I take my foot off the brake. After reproducing the issue a couple times (~ 10 minutes later) and documenting the issue with a video, the check engine light eventually came on and the dashboard displayed: "PARK malfunction. Engage parking brake when parking vehicle." Which quickly changed to the warning message: "Shifter system malfunction! Service immediately" The vehicle would no longer let me place it in "park" and it remained on in "accessory mode" and I was unable to turn off "accessory mode" since the vehicle could not be placed in park. However, neither of these error messages appeared the 3-4 times I was able to place the vehicle in "park" and then observe it roll back. The vehicle has been towed to Northwest Hyundai for inspection/repair. >> How was your safety or the safety of others put at risk? The car rolling uncontrolled is a huge safety hazard to anyone that happens to be in the path of the car. It is also a huge safety hazard to any occupants that might remain in the vehicle when the driver exits after placing it in park. >> Has the problem been reproduced or confirmed by a dealer or independent service center? Not yet. The service error that appeared prevented the car from being placed in "park". However, I was able to capture a video of the problem. >> Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? No, there were no error messages of any kind.
