Hyundai Santa Fe slipping problems

Filed Nov 6, 2026 · Transmission · IN

Since delivery in XXX my 2024 Santa Fe 2.5T AWD often fails to accelerate from a stop. When I press the gas, there is a delay before it engages, like a slipping clutch, and on inclines it rolls backward before it catches. It happens most in the first few minutes after the car is started or restarted, when stopped on a slope, and it seemed worse in hot weather. On XXX, I was pulling out of a gas station onto a very busy highway in [XXX] right after refueling. I waited for a larger gap so our older daughters, driving behind us, could pull out at the same time. When I pressed the pedal, the car moved only a few feet, just enough to put us into the road, and stopped. I floored it again and the car still did not move. Oncoming vehicles in both directions, traveling about 50 mph, had to slam on their brakes, nearly causing the traffic behind them to collide, but they avoided hitting us broadside. My husband and our two youngest daughters were in the car with me. I mentioned the failure to accelerate and the lag at several earlier service appointments, but it was never written up or looked at. Those visits usually took only 15 to 20 minutes. On XXX, when I picked the car up after a week-long repair for other problems, I asked the service counter to log this complaint. They had already printed my paperwork and told me to bring it up next time. The car has been back in the shop since XXX, and the technician has not been able to duplicate the problem so far.

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 have had issues with my dual-clutch transmission slipping gears in multiple ways while driving; most commonly while in drive and going downhill the tachometer will aggressively rev when just idling and without pressing the accelerator. Also, when trying to reverse out of a parking space on an incline or decline multiple times I have rolled forward as if in neutral and receiving no power to back the vehicle in reverse. Previously owned a 2023 sonata with similar transmission issues and blew a cylinder on the highway within a year of ownership(engine knocked out while driving about 65 and just lost power and had to pull over on side of highway. Went to dealership yesterday for regular maintenance and told them about transmission issues. They checked vehicle for any tcu updates and there were none. Test drove it and said it was driving normal. I know it’s not driving normally/safely. What can I do?

When accelerating the transmission slips. My mechanic said Hyundai has a memo saying they are making a new torque converter due to these problems, and I will need a new torque converter. The torque converter is on backorder and according to my mechanic, will not be available for many months; thus indicating there are many other folks with the same problem. This is very dangerous when accelerating, as the speed drops off due to the slippage, and can put me in a dangerous position if I need to accelerate to avoid a potential situation. It has also presented issues from a dead stop, pulling out into traffic, where the slippage puts me at risk. This has been going on for quite some time, and my mechanic has been doing what Hyundai memos instuct.

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.
