2023 Hyundai Santa Fe problems

“My 2023 Hyundai Santa Fe Calligraphy has experienced transmission problems since it was new and currently has approximately 20,000 miles. I brought it to the dealership approximately three to four times for these concerns, but I was told they could not find a problem or any diagnostic codes. Recently, while driving on the highway, the vehicle lost power and would not accelerate even with the accelerator pedal pressed all the way down. I had to pull over to the side of the highway. Without turning off the engine, I shifted into Park and then back into Drive. The vehicle began moving again, but the transmission continued slipping. On [XXX] I brought the vehicle to Key Hyundai of Manchester for scheduled maintenance and again reported the recurring transmission problems. The dealership requested a diagnostic fee of more than $200, which I declined because I had repeatedly reported this problem since the vehicle was new. They completed the scheduled maintenance without performing the requested transmission diagnosis. After leaving the dealership that same day, the vehicle repeatedly malfunctioned while I was driving, and the check engine light came on. I returned…”

“I was at a stop light, when it turned green I accelerated and the car automatically implemented emergency braking. No one was in front of me. Thank goodness no one was behind me or they would’ve rear-ended me.”

“Collision warning sensor alarm randomly comes on my dash and my car slams on the breaks. Very dangerous, I’m scared to drive down the highway going 60mph. 80,109 miles 2023 Hyundai Santa Fe. I have not brought it in to a Hyundai dealership because they want a diagnosis fee and everything else. Hyundai should fix it. This alarm has happened several times than it will go away and come on like 3 times in a row, usually daily when I use the car”

“I was driving, and the SUV all of a sudden lost power. I was trying to press harder on the gas pedal to keep up with the traffic, but the SUV was stalling. The SUV would not move, and as I kept trying to press on the gas pedal, a roaring noise like something was trying to turn but the engine kept trying to move the car. It felt like something in the car was trying to move but something kept slipping. I had to turn the car off in the middle of the street and restart it before it would move. Cars were blowing their horns. This is a safety issue and a dangerous Problem. The SUV just did the same thing a few days ago. I am calling the dealer to see what is wrong. I brought this car new 2023. It is under 12,000 miles”

“No crash, injury, warning lamp, message, or loss-of-braking event occurred. The issue involves the brake hydraulic system and the fluid specified for my 2023 Hyundai Santa Fe Calligraphy. Hyundai’s owner specification requires SAE J1704 DOT-4 LV / ISO 4925 Class 6 brake fluid. During a brake-fluid exchange, an authorized Hyundai dealer installed BG 84032, which BG identifies as conventional DOT 4. BG sells a separate product, BG 84132, identified as Low Viscosity DOT 4 meeting ISO 4925 Class 6. The original BG 84032 has since been correctly replaced by an independent repair facility and is not available for inspection. I have attached all materials I believe are relevant. Both BG product specifications are available from the BG website. My safety concern is that conventional DOT 4 does not meet the Class 6 low-temperature viscosity requirement specified for this model and other high-volume Hyundai models, which could affect ABS/ESC hydraulic response under low-temperature, icy, or snowy conditions. The Hyundai dealer’s repair order documents installation of BG 84032, consistent with the MOBIS part listing for the vehicle. An email exchange between the dealer…”

“While traveling on [XXX] from [XXX] to [XXX] XXX, I initiated the adaptive cruise control. While engaged, with no other vehicles or other impediments on the roadway in front of me, the emergency braking system engaged and attempted to stop the vehicle. The first time this happened, I pressed the accelerator which disengaged the braking action. Later I reengaged the cruise control and after a few minutes, with no traffic near the vehicle, the same action happened again. I disengaged the adaptive cruise control and drove the vehicle manually with no further problems. I have scheduled an examination of the vehicle with a Hyundai dealer but have read of 25-30 similar issues with no resolution by Hyundai. This is a safety issue that will eventually cause an accident and needs to be resolved.”
