2024 Hyundai Santa Cruz: sudden loss of power

Filed Apr 25, 2026 · Acceleration, Fuel system · DE

While driving on I-81 up a steep grade, truck suffered a sudden power loss, with speed dropping to 35 MPH from 65 MPH. Attempts to regain speed failed and it felt like truck downshifted to a lower gear. 35 MPH continued until I decided to use truck cruise control to attempt to gain speed. I was worried about tractor trailers hitting me due to low speed. Finally got vehicle to 65 MPH but would not go above 65 MPH. Rode that way for 100 miles ( trip home was ~ 200 miles) finally in lighter traffic when I had to brake, I tried to use gas pedal to maintain speed.and it worked. Rode the last 100 miles normally. I was at great risk when truck went from 65 MPH to 35 MPH. This is the second incident vehicle suffered in the last 2 months.. Dealer was not able to diagnoise problem. Vehicle had no warning lamps to warn me in both instances.

Sporadically, when shifting from first to second gear, the engine/transmission will stall, causing a loss of power for several seconds. This is generally when pulling away from a stop sign/light into traffic. I picked a single date below, but this continually happens from time to time.

As I was attempting to accelerate at a stop light, once I got to 10mph I lost all power and the vehicle appeared to be in neutral, even though it was in gear. The engine just revved and would not go any faster. It appeared that the transmission just completely slipped out of gear. I had to figure out a way to exit the road as I was in full rush hour traffic. When I re-entered traffic to try again, the same thing happened and I exited into a side street neighborhood. The third time, the car did accelerate although it was rough shifting. This problem is extremely unsafe. This is a brand new car and unacceptable. When I researched this issue online, it appears to be a very common issue in the 2022-2024 Hyundai Santa Cruz’s. I hope that this will be investigated.

We purchased our 2024 Santa Cruz [XXX]. On [XXX] the Santa Cruz we purchased from Korum Hyundai Dealership died on the highway as my husband and I were heading to town through the mountains. We had to roll to the side of the road as the Santa Cruz just lost all power and would not accelerate, it just died and lost power. I thought it was a fluke. My husband was driving. I asked if he had hit a button or something, he said no. Turned the ignition to off and he restarted the Santa Cruz and it turned on. On Saturday, [XXX], driving on [XXX] , heading west from Glenoma, Washington to Morton, Washington driving approx 60 mph when the Santa Cruz lost all power again driving down the highway. It was a very dangerous situation! We have logging trucks and semi trucks up and down that highway going speeds of 60 mph and more! I lost all power and had to roll to the side of the road in the Santa Cruz. Some of that stretch of highway does not even have places to pull over and some of that highway has metal guard rails as well as drop off cliffs. EXTREMELY HAZORDOUS SITUATION to have the Santa Cruz simply lose all power going down the highway! On this date the Santa Cruz had 4522 miles on it. I looked at the dash panel to see if there were any warning lights and made a point to look at the mileage. There were no warning lights. Nor warning messages. April 3rd the 2024 Santa Cruz Night was dropped of at the Korum Hyundai Service Dept. The dealership has had the vehicle for 3 weeks and states they cannot replicate the problem. There are no warning lights. Since then I have been on Hyundai Forums and have multiple people tell me the exact same situation has happened to them. They ended up finding out it was the fuel injectors. The forums also stated that the dealership could not replicate the issue when take to service department for other owners.

On one occasion on interstate at highway speed during summer, dry conditions I was driving at approximately 60 mph and was not accelerating while maintaining average pace in traffic. For no apparent reason the engine lost all power. I was forced to drift over in a hazardous manner to reach the right shoulder. When the power was lost the engine was still on and operating, multiple presses on the accelerator did not provide any power or increased engine noise. Once stopped I checked that the truck was still in Drive gear, engine was on and parking break or assist was not engaged. The drive Mode button was in the Smart setting. I placed the truck in park and turned off the engine. I turned the truck back on and placed it in drive and the truck began operating normally. I feel this is a safety hazard as an unexpected loss of power could cause a collision or loss of control under driving conditions. I will advise my dealer, dean hyundai ballwin mo when taken for oil change 12/9.

My truck lost power climbing a pass. My speed dropped from 60 mph to 20 mph while on a state highway outside Yellowstone NP where traffic can be heavy. My error codes have indicated that it is a problem in the fuel injection system. I have had electrical harness on that system replaced 4 times in 6 weeks, 2 of the times took place at the dealership during repair. My truck is still not operable.

Our 2024 Hyundai Santa Cruz SE had a loss of engine power while attempting to accelerate into traffic after stopping at an intersection four times since purchase in November 2023. The engine did not go above idle for approximately 15 seconds while the gas pedal was pressed half way down. The vehicle barely moved into the road and then gained power after what seemed to be the same as limp mode. No codes were set, no warning lights, no unusual noises or vibrations. Vehicle runs great at all other times. These vehicles were recalled in 2022 for a faulty transmission pump and software that caused this issue. Why does Hyundai still allow it for a 2024 model? Also, the backup camera stays on when driving forward now. We have the vehicle at the dealership awaiting their feedback
