2023 Hyundai Santa Cruz power train problems

“Hyundai Santa Cruz with transmission problems. 5 attempts to repair and manufacture failed to. Last time, vehicle had a sudden transmission failure while driving. Car stop responding to acceleration and transmission was not switching gears, that could had cause loss of control, especially in high-speed or high-traffic situations. Luckily it was very early in the morning, not much traffic and before (0.3 miles) from taking a high-speed interstate. Vehicle is not safe to drive and according to a research I made, other vehicles of same brand, model and year are facing same issues.”

“On [XXX], I went out to start my 2023 Hyundai Santa Cruz (SC) to leave work to go home. It was difficult to start, however, it started. As I entered [XXX] , i was nearly rear ended by another car, because my SC lost all acceleration. I turned on my hazards for SAFETY and then began to try to accelerate again and was only able to get up to 45 MPH and then was turning 4,000 RPM. I limped my SC home where I had it towed to a local Hyundai dealer as it has roughly 38,000 miles. The dealership had it for 3 days, but couldn't duplicate the issue, so no repairs were done. The Hyundai Santa Cruz has KNOWN transmission issues and the fact I was nearly rear ended could've caused a nasty wreck, resulting in more damage or even a fatality. I reported the issue to Hyundai customer service on the 11th of September (Case #[XXX]). However, in the response from Hyundai, basically saying they "experiencing a high e-mail volume" and responses may be delayed. As of 9/13/2025, I have not received a call or email from Hyundai's customer service.”

“car flashes transmission low fluid and gives a code of p193b-79. when trans downshifts upshifts will not happened. to clear the problem you have to turn car off and on , and then normal operation resumes, but shifting is now slower. and sluggish. this is the second transmission to have this problem. Seem hyundai has not fixed it from the 2022 recall.”

“Vehice experienced FULL power loss several times. Truck taken to dealership and stated no problem found. Incident happened again a week later. Determined wires can become lose from battery terminals for no reason.”

“My 2023 Hyundai Santa Cruz, which I bought new, has gone into limp mode twice in 8 months, losing power while I was driving and letting me go no faster than 25 MPH. The first time, in April 2024, I was on [XXX] in Hartford CT. I called 911 because I was certain I would be hit by a car. There was no warning lights to indicate a problem. I was able to get off the highway and had it towed to Meriden Hyundai in Meriden CT. They said they could find nothing wrong. On [XXX], my vehicle went into limp mode again. I was able to drive it to the same dealer since I work nearby. Again, they say they can't find the cause. I have been without a vehicle since then. The car is a danger to drive, and Hyundai has not resolved the matter, though I've been in contact with corporate representatives. Limp mode has caused many crashed across the country. It is designed to protect a car from a mechanical problem - but the system itself puts drivers at great risk. My hope is the NTSB will investigate my case and this national problem before more people are injured or killed.”

“Transmission failed to transfer adequate power to the wheels when the accelerator was pressed from a full stop at the entry point of an intersection. This led to the the vehicle slowly entering the intersection for 2 feet over w seconds. Transmission then transferred full power to wheels. Vehicle was then driven to the entrance of the nearest parking lot, which required a left turn. Vehicle again had only a partial transfer of power to the transmission, leaving the vehicle temporarily blocking part of the oncoming lane which could be dangerous if there was any oncoming traffic. A "check transmission oil" message flashed on the driver screen; however, this vehicle has a sealed transmission and it is impossible for a driver to check. Vehicle was then taken to the nearest dealership for evaluation.”
