Mileage when the problem started

Owner reports

Selected complaints filed with NHTSA by 2023 Hyundai Santa Cruz owners, lightly cleaned up (personal details are redacted by NHTSA).

The contact owns a 2023 Hyundai Santa Cruz. The contact stated while slowing down at approximately 25 MPH, the vehicle downshifted roughly and would jolt while shifting into gear. The contact stated that the failure had been occurring intermittently. Additionally, the contact stated that the RPMs would remain high while he was at a complete stop. The contact stated that the RPMs would rise above 3,000 RPM while depressing the brake pedal, and he would turn the vehicle off to stop the engine from revving. There was no warning light illuminated. The contact had taken the vehicle to a local dealer, where it was diagnosed that the throttle body needed to be replaced. The part was replaced; however, the failure persisted. The vehicle was taken back to the same dealer. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was approximately 4,000. …

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. …

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 [redacted] 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 [redacted], 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. …

On [redacted], 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 [redacted] , 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 #[redacted]). …

On 3 separate occasions this has occurred . When accelerating, the engine or power train completely loses all propulsion. Twice I was starting a left hand turn and crossing oncoming traffic. On one occasion I was turning right onto a 50 MPH highway and quickly veered off the road onto the berm. The only item on dash board flashing on the third incident was the cruise control preset and it was flashing 20. At the time I was not using the cruise control and I did not set it for 20. No dash board warning lights lit during the first two losses of power. I reported it to the dealer. Today I had a maintenance appointment and inspection at the dealer. After that inspection, they informed me that they found no codes to identify the issue. I should let them know if it continues. My 3 failures happened at approximately 10,000, 15,000 and 20,000 miles. …

The car has 1,360 miles and is only a month old since I bought it. Car sat for 8 hours at my work parking lot. When I went to start it it ran rough like an engine misfire for about 10 seconds then normal. When I drove off with engine cold... the transmission would not shift up and was at 4,000 rpms. The accelerator pedal was not responsive.. even flooring it yielded no acceleration and the car would not go over 25mph. No check engine lights or trouble lights. I was able to put the automatic into paddle shift mode but the car still did not want to accelerate and when it did it seemed to get stuck at 3500-4000 rpm and no accelerator input. Shut the car off then back on again after I pulled over because the car would not accelerate. - now it is fine with no issues it seems like. Took to the dealer and they could not recreate the issue .. …

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.

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.

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.

Truck stopped shifting corrrectly with 11550 miles. Would get stuck in 8th gear or 2nd gear. Shifting into manual mode produced no response. I brought it to the dealer 6/12 and upon receiving the P1c2d03 code, they told me it would be a hp oil pump. Looking the issue up, it seems the 2022's had this issue and required a new trans, not oil pump. A week later (6/20) dealer ship calls and says it's fixed with the oil pump. I go to collect my truck and don't make it out of the lot before it stumbles and gets stuck in 2nd gear again. Left it with the dealer again, but haven't heard anything since, and they won't return my calls. Currently 7/9 with no response.
