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.

Vehicle has 2k miles on it and it experiences a loss of power from a stop when accelerating. The vehicle shakes as if it is not getting enough gas similar to a manual transmission if you took your foot off the clutch when the vehicle was in 1st gear. It happens about once a week at random times, no codes produced. Dealership advises with no codes displayed and their inability to recreate the concern there is nothing the manufacturer will allow them to do. Dealership has had the vehicle for over 3 weeks. This is becoming a more common issue, yet nothing is being done by manufacturer to address for consumers. If my wife or I are operating the vehicle and cannot get out of the way of an oncoming vehicle due to a sudden loss of acceleration this poses a great risk for serious bodily harm or injury.

My new 2023 Santa Cruz lost power on freeway. The dealer performed a transmission software update; however, the issue was significantly worse after the upgrade, causing me to lose power again on a busy freeway. The vehicle was towed back to dealer. Today I was told the transmission needs replacement. Transmission failure is a dangerous safety issue. It’s my understanding that the 2022 Santa Cruz was recalled for transmission issues. Please do the same for the 2023 model so others don’t experience the terror of suddenly dropping power while surrounded by 65 mph+ cars. Thank you.

The dual clutch transmission frequently, though not consistently, malfunctions under acceleration. Typically, when accelerating from a stop, when the transmission shifts from 1st to 2nd gear, the clutch will slip causing a sudden loss of acceleration and shaking of the vehicle. Hyundai calls this a "judder". This causes a safety issue to myself and others because of the unexpected sudden loss of power. If this occurs while crossing another street or pulling out into traffic, it could lead to a collision. I took the vehicle in to Hyundai to have it fixed. They claim to have performed what they called a "judder test" and said that the car passed the test and didn't need any repairs. There have been no warning lights or codes. It is clear to me that Hyundai's testing procedure is inadequate to detect the issue, probably just so they don't have to pay for as many repairs.

Upon pulling onto a street, the vehicle lost power. Pressing on the gas pedal provided no power or faster RPM's. No warning lights were activated. I pulled in and out of two different side streets with very little power. Parked and shut off the vehicle. Restarted and the power returned. This is very unsafe as I was pulling out on a busy street and was unable to accelerate faster than 20 mph. Contacted the dealership and they cannot see the vehicle for nearly a month from now.

On February 10, 2023, I was driving my 2023 Hyundai Santa Cruz on Interstate 10 near Gautier, Mississippi. My cruise control was activated and I was cruising at a speed of about 76mph. Suddenly the vehicle began to rev up to 7,000 RPMs and decelerate. The vehicle then began to coast at around 45mph and pressing the accelerator did not increase the speed but did cause the vehicle to rev. I was able to coast down the off-ramp and turn into a parking lot, however I was nearly hit by oncoming traffic because the vehicle was losing power and I was unable to accelerate. Hyundai Roadside Assistance towed me to the nearest dealership with service center, Jason Pilger Hyundai. By the time the tow truck arrived, the vehicle would not accelerate at all and the driver had to push the vehicle around to the tow truck. After assessing the vehicle, the Hyundai dealership called Hyundai Tech Line and told me that my 2023 Santa Cruz needed a new transmission. The transmission is also on backorder, so I have no idea when my vehicle will be repaired. Hyundai Customer Care is also refusing to reimburse me the cost of my car payment for a brand new vehicle that I will be unable to drive or access for the foreseeable future. My Santa Cruz only had 5,337 on the odometer when this occurred.

System advised to have vehicle serviced immediately. Vehicle was towed to nearest Hyundai dealership. Further information awaited.
