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.

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. My safety and that of my passenger were most definitely affected each and every time. After 30 seconds to one minute the full functionality returns as if it never happened.

For the entire day (XXX) my car would go limp when trying to shift gears with an automatic transmission. At least 3-5 second delays when pressing on gas and NOTHING happens. Very dangerous when driving in traffic as you cannot get out of the way of oncoming traffic! It finally moves very slowly as if you are in the wrong gear. I would say that the 2 and 4 gears it would not go into at all. As I floored the accelerator, I would see my MPG rating go sky high as no gas was getting into engine. The clutch was slipping when trying to accelerate. Then I got a main display message that said "A possible condition with your Transmission Control System has been detected. A full system check is recommended to be done when convenient, Please contact your local dealership to schedule an appointment". The yellow CHECK ENGINE symbol also came on and stayed lit on the dash. This problem continued for an hour as I drove the car and got home safely. I drove it again an hour later and the same problem persisted again. I also received a Hyundai Bluelink message that a problem had been detected with my Transmission Control System and gave me error code P1C2D03. You may want to look at Hyundai Recall 236 (which only covered 22 Santa Cruz models, even though everything is the same in 23 model and the recall should be extended by you). Also look at Hyundai TSB 22-AT-009H which is my exact issue. These 23 Santa Cruz need to be recalled and fixed before someone gets killed. Went to Hyundai dealer the next day, and the car was operating normally although the CHECK ENGINE light was still on. They performed a software update and said if the problem continues that they will need to replace transmission. I have no confidence that this problem is fixed. Way too many people out there dealing with the same as I found out on [XXX] Thank You INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

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.

so it seems that recall NHTSA Campaign Number: 22V746000 also effects 2023 santa cruz with the dct. While driving got transmission error on gauge once slowed by traffic vehicle would not shift and would just rev, after almost being hit by another car. figure out if you let it rev and then let off gas pedal car would upshift. But this was done by trial and error. this has happened 3 times and first 2 dealer says nothing wrong. code was p193b79. I think the recall to fix these transmissions should be expanded to 2023 and probably 2024 cars.

On 3/22/2024 I was driving my 2023 Hyundai Santa Cruz with 19k miles about 30 mph. My transmission suddenly became jerky without warning and acted liked it did not want to downshift, staying in higher RPMs. When it did decide to downshift, it lurched the vehicle badly. There were no warning lamps or messages prior to the incident. A few seconds after it happened, the check engine light came on, along with a diagnostic notification on my infotainment screen. This indicated a powertrain issue. I then received a notification on my Hyundai Bluelink App regarding a powertrain issue: "Transmission Control System problem, please see dealer".I dropped the vehicle off 3/27/2024 and As of this writing on 5/13/2024 my vehicle has been sitting at a local dealership for almost 50 consecutive days. In the 5 day period between 3/22-3/27 I was instructed it was OK to keep driving the vehicle until drop-off. I experienced 2 more instances of a rough downshift in that time. When I dropped the vehicle off on 3/27, I was told I could take the vehicle home and drive it until they figure out what to do with it and receive instruction from Hyundai Corporate. This was an extremely reckless and dangerous thing to tell me I feel. The local dealer claimed they had not seen this issue before, had to wait for Hyundai Corporate to instruct them on what to do, but a transmission replacement was possible. Eventually they were instructed to replace the transmission oil pump and do a software update. Research shows the 2022 model Santa Cruz had a recall for the transmission oil pump. Recall # 22V746000 "transmission oil pump malfunction, which can result in a complete loss of drive power, increasing the risk of a crash". Yes I believe mine and my spouse's safety, and other's was/is at risk, as this happened as I was driving and there was a previous recall for this exact part. I have informed Hyundai Corporate America of the issue and waiting for responses and resolutions from them.

Vehicle has multiple engine misfires, resulting from faulty fuel injectors. Unable to maintain speed, vehicle controls become hard to control due to vehicles engine misfires. Vehicle has less ten 20,000 miles. Dealership unable to obtain new fuel injectors due to manufacture not having supply. Vehicle in shop longer for 30 days. Contacted Hyundai USA told that Hyundai knows about problem but has so plan to rectify situation.

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.

As I was driving the call 4 times has turned off in the middle of the road. An error message pops up and stays to put the car in neutral and to push the start button to start it. This has nearly caused an accident because it happens when I am driving. The vehicle also threw out error code P023600 Twice and had the check engine light on. The service department has not been able to recreate the issue.

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. The contact stated that the information in this complaint is inaccurate. The manufacturer has resolved the issue now so the contact would like to withdraw this complaint.

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.

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.. no trouble codes or open flash information available for a fix.

On 11/6/2022, while driving the vehicle, it suffered a loss of power and would not accelerate. I was in the vehicle with my wife and 2 young children who felt the vehicle shudder. I was able to drive the vehicle to my home. On 11/7/2022, upon starting the vehicle, I received an error notice from the internal diagnostics system: transmission control P087501 POWERTRAIN TCU. System advised to have vehicle serviced immediately. Vehicle was towed to nearest Hyundai dealership. Further information awaited.
