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.

SAFETY ISSUE: EXPLODING SUNROOF While driving my 2023 Hyundai Santa Fe Limited to work approximately at 6:15AM CST on 9/30/2024 on I-170 southbound in St. Louis, MO, the panoramic sunroof exploded. Car systems did not contain an indicator light or alert that the sunroof was stressed and about to explode. No debris (stone, rock, tree branch, item falling off a car or truck) or falling bird causing this sunroof damage. After the sunroof explosion, I continued driving. No other damage to my automobile or any other car on highway.

The contact owns a 2023 Hyundai Santa Fe. The contact stated while driving approximately 35 MPH and attempting to accelerate, the vehicle failed to respond or accelerate as intended. The vehicle started to decelerate and lost motive power. The contact steered the vehicle to the shoulder and parked the vehicle. After restarting the vehicle, the failure was self-corrected, and the vehicle operated normally. The contact stated that the failure reoccurred several months later. The vehicle was taken to the local dealer who was unable to duplicate the failure. The vehicle was not repaired. The failure mileage was 9,500.

The vehicle's software update initiates upon start-up without the option to delay to a different time. The three updates I've received this year have taken 20-30 minutes each to complete, while I'm traveling. These updates disable hands-free calling, all media and GPS. I can't confirm if any other vehicle safety components are disabled. I don't use them. I contacted my dealer and they stated that's how it works, and there is no option to delay the update. When the update initiates it states the update can continue without the vehicle "ON". Wouldn't it be safer to have the ability to schedule it to a later time when the vehicle isn't being used? Similar to a cellphone update?

I purchased a 2023 SantaFe brand new mid-January, In June I noticed an issue with the car. I called Steele Hyundai in June to get an appointment and was told by Margarita that they didn’t have availability until September. REALLY. So, I went online and filled out an appointment and got an earlier appointment for August. Crazy Right? I then contacted Hyundai corporate to file a complaint, and was given a case number and Tina is the case worker. I brought the car in on [XXX] and left it there till [XXX]. Problem ended up a transmission needed replacement. WOW, quality!! I picked the car up on that Friday and it sat in the garage during labor day weekend. I first got back in the vehicle on Tuesday, [XXX] and knew immediately it wasn’t fixed. I decided to go to a different dealership for service World Car Hyundai in San Antonio and made an appointment for [XXX]. I called [XXX], spoke with Todd and explained needing a loaner. He asked me what I was bringing it in for, told him I had the transmission replaced. He said to give it a week to get the computer to adjust to my driving. SAY WHAT? So, I did and no bueno. I called again on Thursday, [XXX] to bring it in to World Car and spoke with Justin and made an appointment for Tuesday [XXX]. On Saturday, [XXX], we took the car to Austin for my husband to determine what he thought, he said, “this car isn’t drivable”. On Monday, [XXX], I cancelled my appointment for World Car because Todd said Steele knows the history of what work they did, and it would be best. My husband dropped the car off at Steele on Monday without an appointment. The service director Rene is familiar with my vehicle and today when I called him about the car, he said it’s the TRANSMISSION AGAIN. My question is what is wrong with the quality of the engineering or the quality of the service technology. I DON’T trust this car, I need a SOLUTION. I need an answer. I need you to fix this problem with this C INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The forward collision warning system engages and slows the car, often very abruptly, when on the highway and only when cruise control is on. It happens after we have been on the highway for a few hours, thus the dealer cannot reproduce the incident. It happens a few times on every road trip and is very disturbing when there are no other vehicles or obstacles in the road or nearby. We have reported this to the dealer several times and they can find nothing wrong. I provided a photo to the dealer of the dashboard showing the cruise control on, the forward collision system DISENGAGED, and the forward collision warning activated. Dealer states they have recalibrated the system but can replace no parts unless a part is found to be faulty. The latest suggestion yesterday from the dealer was to "get out" of the car before the issue gets worse.
