2022 Hyundai Santa Cruz

My INTEGRATED THERMAL MANAGEMENT (ITM) module went bad in my 2022 Hyundai Santa Cruz. I notified Hyundai about it and found out there are several service bulletins related to this part. My truck was outside the bumper-to-bumper warranty, so I had to pay over $1000.00 to get it replaced. I think it's shitty that Hyundai knows there is an issue with part on 2022-2023 Santa Cruz's and aren't willing to cover it. On top of that, the ECU has to re-calibrated after the repair, which didn't allow me to replace the part myself.

October 2025 while driving the vehicle at highway speeds, vehicle started bucking, losing power and then stalled. The check engine light did not come on. I was able to get off the side of the road and had it towed to the dealer. Dealer found injectors to be leaking and replaced all 4 GDI fuel injectors-mileage was 29,598. On July 1, 2026, again the same issue while driving the vehicle at highway speeds, it started bucking, losing power and stalling when slowed. This time the check engine light came on. Again, it was undrivable and had to be towed to the dealer. Dealer found after 15,000 miles, some of the new injectors failed and were leaking and all 4 GDI injectors were replaced again-mileage 44,492. Both times there was no warning signs that the fuel injectors were about to fail. No other tests were performed on the engine to find out why the fuel injectors are repeatedly failing. I have filed a report with Hyundai National Consumer Affairs because the vehicle will be out of warranty by the end of 2026, and the underlying issue has not been investigated nor resolved. I am concerned that once vehicle is out of warranty, a major issue with the engine will be found that caused repeated failure of the fuel injectors. I did request an extension of the warranty, but was told that normally doesn't happen.

While driving my vehicle on a two-lane highway, I experienced multiple sequential electronic system failures (including the vehicle no longer detecting the smart key), and all electronic systems on the car became inoperative. I lost all instrumentation, including my speedometer and tachometer. At the same time, I also experienced a loss of motive power, and the engine of the vehicle began running extremely erratically before completely cutting off. I attempted to make a safe stop on the side of the road, but after doing so, could not restart the vehicle. The electrical systems of the vehicle continued to behave erratically, and the engine would not restart. I contacted roadside assistance, but they were unable to start the vehicle as well. It was towed to my local Hyundai dealership, but instead of expressing any genuine concern for the significant risk I endured while being placed In harm's way, they refused to fully diagnose the vehicle, and instead accused me of "jumping in reverse," even though I did no such thing (and don't even know what that means). The dealership has no evidence to suggest any such event took place, and simply wants me to pay over $1,800 for replacement of the battery connection terminals, despite being in-warranty. Obviously, the vehicle was already running – there is no way that the dealership's false allegations could possibly be correct. I contacted Hyundai Motor America and was assigned a caseworker, but they were not interested in finding a resolution, and unable to compel the servicing dealership to perform a full diagnostic or provide warranty service. Feeling that I was running out of options for the vehicle to be properly diagnosed, I contacted the dealership where I purchased the car, and provided the photographic evidence & service documentation required. They agreed that there's no way that I could have created this issue, and that further investigation is warranted, but HMA only cares about money – not my or my family's safety.

"The 8-speed Dual Clutch Transmission and engine (Cylinder 4) failed on my 2022 Hyundai Santa Cruz SEL Premium AWD with 37,780 miles. Both components are available for inspection upon request. While merging onto the highway in Sport Mode, the vehicle experienced violent shuddering and noise so severe I believed I had multiple flat tires simultaneously — specifically both front and rear passenger side tires. I immediately activated hazard lights and exited the highway. I was unable to safely operate the vehicle. Other drivers on the highway were also put at risk by my sudden need to exit. The dealer has NOT been able to reproduce or confirm the transmission issue despite multiple documented visits over the past year. However, AutoZone confirmed diagnostic code P0304 Cylinder 4 Misfire Detected on March 19, 2026 via OBD-II scan. The vehicle has been inspected multiple times by the Hyundai dealership over the past year. Hyundai Motor America has an open case on this vehicle and has escalated it to their buyback department. The Check Engine Light illuminated during the highway incident then self-cleared. Transmission slipping, shuddering at low speeds, high RPMs at low vehicle speeds, and failure to shift properly have been reported to the dealer for over one year. This vehicle contains the identical DCT transmission covered under Hyundai Recall 236 but my VIN was excluded despite identical symptoms. Backup camera has also failed twice — a federally mandated safety device."

The contact owns a 2022 Hyundai Cruz. The contact stated that while driving 70 MPH, the vehicle lost motive power but was unable to accelerate above 30 MPH. The contact was able to pull over to the shoulder of the roadway, where the failure persisted. The check engine warning light was illuminated. The vehicle was towed to the dealer, who diagnosed a failure with the transmission. The contact was informed that the transmission needed to be replaced. The vehicle was not repaired. After investigating the failure, the contact related the failure to NHTSA Campaign Number: 22V760000 (Power Train); the VIN was included, but the vehicle was already repaired in 2022. The manufacturer was notified of the failure, a case was opened, and the contact was referred to the NHTSA Hotline for assistance. The failure mileage was 63,000.

Vehicle began running roughly. CEL came on. Began to misfire. Limped it off the FWY under limited power. Had vehicle towed to dealership. Was diagnosed as having bad fuel injectors. Was told by service writer that Hyundai Santa Cruz trucks have been experiencing a lot of injector failures. Looking at the various Hyundai Santa Cruz forums, it appears that this has been a very common issue and has occurred in 2022 through 2025 model year vehicles

On the interstate mid-route, the engine light went on and the car started acting sluggish and slightly shaking on the interstate and would not respond to pressing the gas to accelerate and started to slow down. When I pulled over to the berm it was vibrating as if it was going to stall out. I turned the car off and returned to the interstate with no issues for the rest of my ride (the engine light remained on). On the next trip to the dealership for an appointment to have it checked, I was merging onto the interstate, and again, the car was not responding to me putting on the gas and would not accelerate. Could not push the car over 35MPG, and had to ride to the dealership with the car varying in speed anywhere from almost a complete stop to 30MPH on the berm where I could with flashers, often it felt as if it would stall out. It was a very dangerous & unsafe ride. FYI - The dealership replaced all 4 fuel injectors to fix

2022 Hyundai Santa Cruz Limited 29K miles bought in March at CarMax. I had 6/8 fuel injectors replaced under warranty but it took MONTHS and 5 trips to the dealer. I first had an issue with cold starting the engine and I got a cylinder 3 misfire code, and the first time I dropped it off in April they said they could not repro and sent me home...and then the story got worse.... May 10, 2024 I dropped off the vehicle for a second time due to an intermittent issue with rough cold starts and check engine light. May 24, 2024 All 4 of the high pressure fuel injectors were replaced and I was able to take home the vehicle after two weeks. May 25, 2024 one day later, after the repairs were made, another check engine light DTC P23F5F0 came on while driving the vehicle. May 29, 2024 I dropped off the vehicle due to DTC P23F5F0 as reported by Bluelink . May 31, 2024 The DTC was cleared from the system after a brief diagnosis and I was sent home with the vehicle with no repairs being done. June 1, 2024 One day after I picked it up, DTC P23F5F0 showed up again for me on the Santa Cruz. June 2nd, 2024 I dropped it off for this DTC for the second time. They drove it 250 miles and could not get the light to come back on. July 12, 2024 They released the vehicle over one month later, doing nothing but clearing the light, citing that they needed to replicate the issue for Hyundai corporate to pay for a repair. July 13th 2024, the day after I picked it up for this DTC the second time, the same malfunction indicator DTC 23F5F0 light came back on for me. I finally got the vehicle back in August after they replaced 2 of the low pressure fuel injectors. I've heard from others that failing fuel injectors can cause catastrophic failures on the highway.
