2023 Hyundai Santa Fe Brakes Problems

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.

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.

While driving to work today [XXX] on or around [XXX] on [XXX] from Riverview to downtown Tampa while doing about 68 MPH, my emergency brake deployed for about 6 seconds. The whole vehicle shook. There were no other vehicles around. Quite scary. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

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.

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.

Unknown issue, but the car has auto braked 2x on the interstate going 65mph. No cars were around me nor any objects in the road. It stated auto braking and sensors going off. Resolved itself within 60 seconds, but did almost cause me to be rear ended because a tractor trailer was quickly approaching me.

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. The dealership replaced the sensor and at this time the vehicle is operating as expected.

This hard brake peddle pressure issue started out immediately on an occasional basis but now occurs almost every morning on first start of the day. Press on the brake pedal - it's very hard to deflect - and if you don't overpower it to deflect the pedal enough to activate the brake lights, it won't start. Once you get it started the first time, brake operation will be normal for the rest of the day. A specialty maintenance blog has covered this issue comprehensively. The Hyundai Maintenance website is apparently aware of this potential problem. According to [XXX] , it is likely caused by a malfunctioning brake booster or vacuum leak and recommends taking the vehicle to your dealer for diagnosis and repairs. This is apparently a common problem across multiple Hyundai models since there are several threads on this subject on [XXX] : [XXX] [XXX] [XXX] [XXX] [XXX] I took my vehicle to the dealer where I purchased it and left it with them for a couple of days, Said they had thoroughly tested the vacuum line and found no leaks or problems and that the vehicle was performing as designed. Don't know how serious this is, but I have concerns. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

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.

Upon braking hard and suddenly due to being cutoff on the interstate, it felt as if the antilock brakes did not properly engage but rather grabbed/grinded/scraped. Only when I let off the brake did they disengage. This happened the first time within 2 months of owning the car and with less than 2k miles on it, at highway speeds (65-70 MPH) and this sensation has happened probably 4 times in the 7 months I have owned the car under various scenarios of stopping quickly. In addition, it recently happened when driving 25-30 MPH and coming to a normal stop approaching a stop sign - where it felt as if the brake on the front passenger tire grabbed/grinded/scraped (but not on the 3 other tires). I have taken the car back for inspection at the dealer twice, neither time have they found any issues. In addition, one evening the stability control light flickered, sounded as if the dash was frying/sizzling with no reason - roads were not wet, no leaves, grass or other debris, etc. and speed was 25-30 - this happened twice within 3 miles. Dealer found no issue with car after performing visual inspection of wiring, check of system for code errors, nor driving test to reproduce issue. Had the brakes failed, I could have been in an accident causing serious harm to me/my passengers or whomever I could have hit. I believe the ABS system needs to be replaced or reprogrammed but the dealer refuses to acknowledge a problem exists. Online forums indicate similar (and worse) issues, also with people stating they cannot get a dealer to resolve their problems. This is a serious malfunction of either the electric or braking system in some capacity and should be fixed before people are severely injured or killed.

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.

I was driving on the highway and the car phantom emergency braked for no reason at all.

All lights that come on when you first start the vehicle stay on. ABS, forward collision, rear collision, side mirror check, down hill brake, etc. The brakes and brake pedal would lock up when attempting to brake. Pedal stays locked but the wheels didn’t seem too. Brake system wouldn’t respond to pumping the brakes the pedal stayed frozen. It could have caused me a serious accident.
