2023 Hyundai Santa Fe: shudder or vibration when accelerating

Filed Jan 17, 2025 · Brakes, Driver assistance · CA

In January, 2024, my vehicle (2023 Hyundai Santa Fe) started shuddering when brakes were applied at high speed, on quick or hard stops, in stop and go traffic, and especially going downhill. I had only been driving the vehicle for about 5 months. I took the vehicle to an independent mechanic, who explained that my front rotors had burn spots. He recommended that I have them resurfaced. I did not want to pay for the problem to be fixed when I believed it was a factory defect and should be covered by warranty. I asked the Mission Hills Hyundai dealership Service Department to investigate and correct the problem, because I felt that my family's safety was jeopardized by faulty brakes. They showed me the burn spots on the front rotors and recommended resurfacing. They said I could wait for the pads to wear down and do the resurfacing at the same time as the pad replacement. Their estimate for resurfacing was higher than the one from my mechanic. I found a Hyundai Technical Service Bulletin, Number 23-BR-004H, which described the exact defects of my vehicle. I returned to the dealership with the TSB in February, 2024. They replaced the two defective front rotors and front disc pads at no charge. The shuddering was no longer evident, and I thought the problem was resolved. However, 10 months later in December, 2024, I once again experienced the shuddering while braking on the freeway while going downhill and when slowing for stops from high speed. Since I had been told that the new rotors and pads were covered by warranty for 5 years or 60,000 miles, I returned to the dealership on 1/16/25 and asked them to evaluate the brakes again. They said that the front rotors again had burn spots. They once again recommended resurfacing at a cost of $249. I reminded them that there was a warranty on the new parts, they claimed that the only warranty was for the original parts that had been replaced. They agreed to resurface no charge. Please investigate and respond to my complaint.

Automobile approached and stopped at stop sign. When accelerator pressed to continue, car remained in place, shuddering (as if transmission were slipping),and making significant noise. Car would not shift out of gear, nor move. Operator shut off car and then restarted car. Car started normally and was in park without shuddering. Expectations at busy intersection was that it was my turn to move and did not do so, creating doubt on what my car might do next. Traffic flow was briefly confused and some drivers honked and were unsure what they should do. This could have caused an accident with an impatient driver re-ending my car, or with others going through the intersection "out of turn" and unclear on my situation. No lights or other warnings were displayed before this incident. It has not re-ocurred. I brought into the dealer who had no other reports of this type of behavior.

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. I feel extremely unsafe in this vehicle and the issue is still not fixed as I have a claim in process with the manufacture directly. The claim was put in on 12/7/24 where I was told I would be contacted within 2-3 BUSINESS DAYS by a manager due to my claim being escalated. It is now 12/15/24 and still NO CONTACT from Hyundai. The vehicle shuddering is increasingly worse and worse and I feel very unsafe in this suv.

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.

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. Hyundai has thus far refused to cover the full cost of repairs, totaling over $1,400.00.
