2023 Hyundai Santa Cruz

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.

The contact owns a 2023 Hyundai Santa Cruz. The contact stated while driving approximately 65 MPH with the cruise control engaged, the vehicle started losing motive power. The contact stated that the check engine warning light was illuminated. The contact stated that the vehicle slowed to approximately 15 MPH while depressing the accelerator pedal and failed to respond as needed. The contact was able to drive the vehicle to the residence. The contact turned off the vehicle and attempted to restart the vehicle; however, the vehicle failed to restart. The contact had the vehicle towed to a dealer who diagnosed the vehicle and determined that a fuel injector had failed and needed to be replaced. The vehicle was repaired. The manufacturer was not informed of the failure. The failure mileage was 13,803.

Loss of power during driving No warning or warning lights vehicle would not accelerate engine speed increased only to 3k rpm’s but vehicle would not accelerate This could have been life threatening if I was in traffic Shut vehicle off and restarted problem when away From looking on forums this is an issue with the Santa Cruz

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)

The contact owns a 2023 Hyundai Santa Cruz. The contact stated that while driving 60 MPH with the cruise control feature activated, the braking system erroneously activated causing the vehicle to abruptly decelerate. After parking and restarting the vehicle, the vehicle operated normally, and the failure was corrected. The vehicle was later taken to the local dealer who was unable to determine the cause of the failure. There was no repair performed. The contact stated that the failure had reoccurred. The manufacturer was not yet contacted. The failure mileage was 1,000.

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.
