2023 Hyundai Santa Fe: transmission slipping

Filed Oct 5, 2026 · Transmission · CT

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 to the dealership. A scan showed three fault codes related to the transmission, clutch, and a sensor. I asked to leave the vehicle and receive a loaner because I feared another loss of power on the highway could cause a rear-end collision. I was told the person who could authorize a loaner had left for an appointment, could not be contacted, and that I should return Monday. On [XXX], I called and spoke with Anthony, whom I was told was in charge. He told me I needed to bring the vehicle in and would have to join a waiting list for a loaner. On [XXX], I brought the vehicle back, and it is currently at the dealership being evaluated. My primary concern is safety: recurring transmission slipping and a loss of acceleration that left me unable to maintain speed on the highway.

The AWD coupler has failed and the rear wheels feel like they are slipping and catching when I accelerate from a stop, particularly when turning. The car was taken to the dealership and inspected, but no longer under warranty as we are not the original owners.

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

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.

when I tried accelerate, the car jerked and then the transmission began to slip and I coasted to a stop. I cranked the car and slowly began to drive the car while it felt like the transmission was slipping. My first thought was that the transmission was low on fluid but later found that this is a sealed transmission. Luckily there was no traffic during this incident. There was no warnings lights or any warnings whatsoever.
