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)

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.

While driving the vehicle during winter the temperature of the engine dropped due to thermostat failure leading to no heat in the cabin and a check engine light. Vehicle was towed to the dealer as this failure can cause both engine damage and is unsafe for the occupants in freezing temperatures.

11/14, 2023 Drove about 2-3 miles when all warning lights on the dash came on like a Christmas tree. I was coming to a 4 way stop, both roads were 55 mph speed limits. There was a car behind me and another coming to a stop from the left. I wanted to get across the intersection to pull over and assess the situation. While trying to get across the intersection there was no response to the throttle pedal, ended up idling through the intersection at 4 mph. After getting across I pulled over and turned the truck off, let it sit for maybe a minute or so. Then I restarted and the only warning light that stayed on was the service engine warning light. The throttle showed response at that time, I started driving slowly and eventually felt it was ok to gain speed. Was able to drive at posted speed limits. 11/1582023 I took truck to Hyundai service department. 11/17/2023 Hyundai service advisor called and stated the tech support line told them to try replacing the wire harness because of erratic readings. The harness was on backorder until 11/27/23. 12/4/2023 Service advisor told me the harness was now on national backorder until 12/7/23. Again he said he will contact me when the part comes in. Truck went into service on Nov 15, 2023 and now Dec 17, 2023 tech line suggested wire harness to be replaced is still not available.

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 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.
