Selected complaints filed with NHTSA by 2023 Hyundai Santa Fe owners, lightly cleaned up (personal details are redacted by NHTSA).

The contact owns a 2023 Hyundai Santa Fe. The contact stated that while his wife was driving at approximately 65 MPH and depressing the brake pedal to slow for a vehicle that had passed and switched into the lane she was driving, the vehicle was shuddering. The contact stated that as soon as she had stopped depressing the brake pedal the shuddering ceased. The contact stated there was no warning light illuminated. The contact stated that the shuddering when the brake pedal was depressed was intermittent but was recurring at various speeds while slowing down. The contact had taken the vehicle to a local dealer, where it was diagnosed and determined that the brake pads and rotors needed to be replaced. The vehicle was not repaired. The manufacturer was informed of the failure. The failure mileage was 18,756.

The contact owns a 2023 Hyundai Santa Fe. The contact stated that while driving approximately 35 MPH, the downhill assist, traction control, auto stop, blind spot, and ABS warning lights illuminated. The contact was able to pull over and called the local dealer and was informed that the vehicle was safe to drive. While driving at an undisclosed speed, the brakes independently activated. The vehicle was taken to the local dealer, where it was diagnosed that the wheel speed sensor needed to be replaced. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 2,000.

While parking, the brakes failed. Although the brake pedal was correctly and completely depressed the car failed to stop until it hit the building causing damage to structure and injuries occurred to passengers. The brake pedal pulsated but the car did not stop. Prior to this, the brakes would sporadically pulsate while braking. There were vehicle health issues that were reported.

Over the last Tom th, I have encountered some pretty scary issues with my brand new Santa Fe purchased in April. Last week, while driving, after I turned on adaptive cruise control, the system alerted me that "smart crusade control conditions weren't met" and kept trying to engage the front left brake - this occurred three days in a row. After turning off the smart cruise control and entering residential roads, the front left brake tried to engage in a manner that seemed consistent with ABS issue. I brought car in two days later to Dublin Hyundai and they said they couldn't find anything wrong with it. I picked the car up yesterday morning and then last night while driving on the highway, it alerted me that I need to "check highway drive assist system" and a warning light came up. …

I purchased my 2023 Santa Fe brand new off the show room floor in Jan 2024. After about 6k miles when braking on the highway the entire vehicle would shudder and shake including the steering wheel. I took it into the dealership where I was informed this is a KNOWN ISSUE with this year/make/model with the rotors. They claimed they would turn the rotors but if the issue persists they would replace them. About 2k miles later (apx 2 months) the shuddering happened AGAIN. So I made an apt to get them replaced where the new service tech tried to tell me again this is a KNOWN ISSUE but now I would be responsible for a $250 replacement of the rotors. I refused to pay as they are within the 12k or 1 year warranty and they refused to replace them. That service tech also said the day prior he had to deliver that news to 4 OTHER patrons about the replacement of their rotors. …

Car was purchased January 21st had 3000 mile on it when service was needed for these issues. On march 23rd as I started driving my car wouldn't go above 30 mph, when pressing on the gas pedal the car wouldn't accelerate, the rpm gage would go to 4 but engine wouldn't make noise car wouldn't speed up. I put the car in park and back in drive with no improvement. I pulled off at a gas station restarted the car and it was fine. During this time the auto on off button was orange on the cluster which I had never seen it that color before. Was looked at by the dealer but wasn't reproducible. Not sure the cause, but safety was in jeopardy due to not being able to go with speed of traffic. …

Whilst driving the vehicle a number of warning lights appeared on the dashboard. This occurred after the vehicle was brought to a stop at a stop sign. There were no outside influences before or after the warnings began. The vehicle remained operable and was driving back to our residence approximately 1 mile away. I made an appointment with the local dealership to investigate the issue. The appointment was made for the following day. Whilst driving the vehicle to vehicle to the dealership on the following day the brakes became temporarily inoperable forcing me to leave the road and hit the right hand kerb. After pumping the brake pedal several times the brakes re-engaged and I was able to stop the vehicle. The dealership have explained that a rear wheel speed sensor (ABS) had failed and was sending messages to the the braking system which made the braking system inoperable. …

Brake rotors warped. Beginning at approximately 5k miles, the steering began exhibiting a juddering upon applying braking. Over time, the juddering became more pronounced. At approximately 15k miles, I took the vehicle to the dealer. The dealer confirmed that the brake rotors were warped. The defective brake components put my safety at risk, as well as the safety of my passengers and others traveling on the road by impairing my ability to safely stop the vehicle and impairing my ability to safely operate the vehicle while braking. There were no safety lights or warnings. I am aware that there has been a technical service bulletin for this exact issue for this model/year vehicle. Neither Hyundai nor the dealer ever altered me to the possibility that the brake rotors might warp due to defective components. …

I was travelling at 50mph a car pulled in front of me and stopped unexpetedly. I braked hard. My car began to slow, but the brake pedal went to the floor and did not slow, AFter a few seconds, the brake pedal came up from the floor and braking was resumed. I held the pedal to the floor the whole time trying to stop. It was as though the braking system failed and recovered. There was no pulsing felt on the brake pedal typical of ABS working. After my car resumed braking thte collision avoidance system took over and the car stopped just inches from the stopped car in front of me. I had just taken the car in for dealer service at 24,200 and everything was supposedly checked out as required by maintenance. I have contacted Hyundai but have not gotten a response yet.

The vehicle front brake disks are not compatible for this vehicle. The action of braking causes heating of the disks. The disks warp due to the heat. The result is when braking at highway speeds, the entire front end vibrates excessively. This is unsafe in wet or snowy conditions as this greatly decreases the braking efficiency. The first time this was observed the vehicle had 22,000 miles and the dealership machined the rotors. The second time it happened at vehicle mileage of 32,000. Once again the rotors were 'machined' by the dealership. The action of braking at highway speeds and the resulting front end vibrations is a troublesome event. If this occurs a third time, I will try to find and install non-Hyundai disks.
