2023 HYUNDAI SANTA FE Complaints

Emergency brakes engage while driving for no apparent reason. This has happened on several occasions over the last 6 months.

Santa Fe will randomly experience inability to accelerate. I will hit the gas pedal, the engine will rev all the way up to power, it will slowly crawl forward and than violently accelerate. From the time I hit the gas pedal to the time it actually starts moving takes several seconds. It does this every time I come to a stop once it starts. It has done this 4 occasions now. It puts me at significant danger trying to turn across traffic. In general, it not accelerating as you would expect is a very dangerous situation. Dealer has had the car for over a month and has had the car reproduce the issue. The HEV light and check engine light had come on a couple of the occurrences.

As my wife and I were traveling down the interstate at 45 mph, we heard a loud POP, but we were unable to figure out where it came from. Just a few seconds later, the sunroof exploded into a million tiny pieces of glass that partially rained down on our heads and shoulders. It was quite a startling sound. There was a hole about 8 inches across in the moveable sunroof and more pieces were continuing to fall out. To protect our heads, I closed the shade. There was no evidence of an object striking. Windows were all closed when the incident occurred.

Vehicle has gone into limp mode 2 times in the past week. Power when accelerating would not exceed 30 mph when pushing the gas pedal to the floor. Had to pull over as I was getting onto the highway and stop/ power down the car and restart.

Twice, the car refused to switch from EV mode back to gas mode. This resulted in the hybrid battery dying and the car losing power. The first time, I was merging onto the freeway and the gas pedal was all the way at the floor, but I was only maintaining speed (not accelerating). Both times, the car was driveable for approximately one mile on the hybrid battery alone. However, a warning came on the dash, “Check hybrid system. Stop safely.” The second time, I was able to pull into a parking lot before the hybrid battery died. The next day, I was able to drive the car normally. The dealership is unable to pull any codes or replicate the issue. Unfortunately, it only happens intermittently and we have not identified a common theme for the failure.

The rear section of panoramic sunroof exploded. We were traveling approximately 60 MPH on HWY 395 crossing the bridge on the Columbia River between WA and OR. Suddenly we heard a very loud explosion. When we stopped to investigate we found a hole in the sunroof. It exploded up and outward. There were very few glass shards inside the vehicle and no debris or evidence of anything that could have caused the breakage. The Hyundai dealer was unwilling to repair it as a warranty item. We paid a glass company through our insurance company to replace the glass. I’m aware that there were problems a few years ago with the Hyundai sunroofs and was advised to file this incident report. It was extremely scary to experience the noise.

The seat belt in the middle seat of the second row did not work. And it was not fastened. So when braking, my child was thrown toward the center console. I think it's a big safety issue if the seat belt doesn't work.

I am afraid of getting myself or someone else killed because there is a 1-2 second lag after stepping on the gas pedal after coming to a stop. This is extremely dangerous. My street empties onto a county road with a blind curve. I have had several instances when the delay between the car moving after I’ve stepped on the gas has lead to oncoming cars needing to slam on their brakes to avoid hitting me. I even called the county and asked that they put up a “dangerous curve sign. They put up a squiggly arrow instead which has not helped. My previous gas vehicles made this turn safely for 20 years. My nephew told me it’s a new feature in cars called “stop and gol meant to save gas. I think saving my life is more important than saving a little bit of gas. It happens all the time so I will put todays date in the space below.

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.

Currently have 518 Diagnostic History Codes (DTC)in memory. Additionally, I have 3 Active DTC’s. The codes are: DTC C160C87 DTC System CHASSIS DTC Sub System LKAS, and DTC C160C87 DTC System CHASSIS DTC Sub System SCC, and DTC C163881 DTC system CHASSIS DTC Sub System SCC FIRST OCCURRENCE: during actual assembly in Montgomery, AL plant. I have asked three Hyundai Service dealers for help. All have tried. Noting noted that contributes to the issues above. At first, my dealer replaced the front camera. Was told it was a heating issue. I have contacted Hyundai BLUELINK service for help. An information report was filed, TWICE. The first report I received feedback that Hyundai’s engineers had corrected the issue. On the following day, the codes returned. A second concern was filed with Hyundai BLUELINK. Hyundai Motor America Case#: [XXX] to wit: “Thank you for contacting Hyundai Motor America. We are in receipt of your e-mail and one of our representatives will get back to you shortly. Sincerely, Hyundai Motor America” Is my vehicle going to fail and cause me injury while operating it on an Interstate highway? This is quite concerning as I drive my car. All I want from Hyundai is to get this issue repaired. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
