2017 Hyundai Santa Fe Sport driver assistance problems

Filed May 16, 2026 · Driver assistance · CA

am filing a formal complaint regarding an official software update provided by Hyundai that completely corrupted the infotainment/head unit system in my 2017 Hyundai Santa Fe Sport. I purchased this vehicle from CarMax less than three weeks ago. The vehicle came equipped with Hyundai Blue Link, so I contacted Hyundai support to activate the service by pressing the Blue Link button inside the vehicle. Hyundai informed me that my vehicle required a software update because the current system did not contain the necessary software for Blue Link to function properly. A Hyundai representative directed me to Hyundai’s official update website and provided instructions for completing the update. Following Hyundai’s instructions exactly, I purchased and formatted a USB drive, downloaded the update using my VIN from Hyundai’s official website, properly extracted the files, and installed the update into the vehicle. During the installation process, the update failed and corrupted the head unit system. The display now continuously shows “Update Unsuccessful” with Error Code 106. Since the failed Hyundai update, multiple vehicle systems no longer function properly, including the backup camera, Bluetooth, hands-free calling, Blind Spot functionality, radio, map/display system, automatic headlights, and automatic radio shutoff when opening the driver door. I now have to manually operate systems that previously worked automatically. I contacted Hyundai customer support multiple times and was repeatedly transferred between departments. I was incorrectly referred to navigation support even though my vehicle has a non-navigation system. Navigation support confirmed this was a Hyundai issue and stated they could not assist. When I contacted Hyundai again, I explained every step I followed, and the representative acknowledged that I appeared to have completed the update process correctly. Despite Hyundai’s official software causing this failure

I was driving on the highway in a mountainous area going downhill. The cruise control was on with the speed set at about 80 miles/hour. Then the car was losing speed, the RPM needle started swinging from left and right. I stepped on the accelerator but the car continue losing speed to 40 miles/hour and continue losing speed. I turned on the emergency light to warn the other drivers and was able to move the car to the shoulder and stopped it without an accident. But the cars behind me could have smashed into my car that day and that would be the last day for my mother (in the car at that time) and me. The car had 41000 miles on it and we had the maintenance done just recently. I did not notice anything else abnormal before the incident. We reported the problem to the dealer and have to pay for the dealer to inspect the car. The inspection has been scheduled but not done yet.

I am concerned about the length of time this recall is taking. My dealership made an appointment for March 15, 2023 and told me it is just to look at it and decide if they need to order the part. This does not sound safe. If something happens between now and then can I hold them responsible. I have made the effort. Can I go to a regular mechanic to have this fixed

When making a left or right 90 degrees turn from a stopped position exiting a driveway or from a stop sign on smooth surfaced roads, upon acceleration, at the midpoint of the turn the forward momentum starts to lag and pressing the gas peddle results in what feels like a loss of or reduction of engine power causing potential for not getting up to a safe speed to merge safely in front of oncoming traffic. Complained to the hyundai dealer that stated was a computer issue having to do with traction control and requires an update which is not available at this time.

I have a 2017 hyundai santa fe sport 2.0 with 8500 miles on it. Since I took possession of this car, I have been having repeated occurrences of engine stalling coupled with the traction control light going on. This happens when I make either left or right turns into traffic: acceleration stalls completely for 2-3 seconds, and the traction control warning light flashes. I cannot get the car to accelerate at all, even with the pedal fully depressed to the floor. The engine revs extremely hard, but the car does not accelerate. This happens on completely dry pavement. There is something seriously wrong with the 2017 hyundai santa fe, and someone is going to die as a result of this problem. I have come close to being rear ended multiple times, and I have nearly been t-boned when taking a turn in front of on-coming traffic. I have researched this problem online, and it is wide spread with hundreds of identical complaints. This needs to be addressed immediately before someone dies in the 2017 hyundai santa fe.

Vehicle hesitates for a second or two when accelerating, both from a fully stopped position, or while driving at low speeds. Did not test high speeds. This can be a safety concern when merging into traffic, especially on a highway. Dealer service said they could not reproduce the issue, but it is very real, and very scary. I had documented this issue several times with hyundai support but they just keep closing the case without any action.
