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.

NHTSA complaint #11749495 — an unverified report by a vehicle owner.
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.
NHTSA complaint #11745435 — an unverified report by a vehicle owner.
The contact owned a 2025 Hyundai Santa Cruz. The contact stated that while driving at an undisclosed speed, a loud popping noise was suddenly heard coming from the engine compartment with no warning lights illuminated. The contact stated that immediately following the failure, the power steering and brakes became inoperable, making it difficult to maintain control of the vehicle. The contact also noticed smoke coming from the engine compartment and was able to forcefully maneuver the vehicle to the side of the roadway. Shortly thereafter, the front of the vehicle near the engine compartment caught fire. After the vehicle was pulled over, the check engine warning light and low oil warning light illuminated. The local fire department responded to the scene and extinguished the fire. The cause of the fire had not yet been determined. The vehicle was extensively damaged and deemed destroyed. No injuries were sustained and no medical attention was required; however, the contact stated that a cough was suffered due to inhalation of smoke and fumes from the fire. A police report was filed. The vehicle was towed to the dealer but was not diagnosed or repaired. The manufacturer was not made aware of the failure. The approximate failure mileage was 7,738.

"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."

Upon starting the vehicle is doesn't act normal and when placed In drive it feels like brakes are applied and it doesn't want to hardly move even when pressing the throttle all the way down. This has also happens a couple times when at a stop and have to pull over and turn the vehicle off and restart. My so. Drives this vehicle and I feel this is a huge safety concern if he is able to get the vehicle moving and can get to a safe spot to shutdown and restart.

On [XXX], 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 [XXX] , 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 #[XXX]). However, in the response from Hyundai, basically saying they "experiencing a high e-mail volume" and responses may be delayed. As of 9/13/2025, I have not received a call or email from Hyundai's customer service. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
NHTSA complaint #11687068 — an unverified report by a vehicle owner.
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

Oil filter cap oil leak problem. Typical problem with this vehicles that require attention. These defective oil leak caps are a safety and environmental concern. The engine almost starved of oil while driving on the highway. Manufacturer has been contacted and are not proactive in taking care of this defect.

We purchased our 2024 Santa Cruz [XXX]. On [XXX] the Santa Cruz we purchased from Korum Hyundai Dealership died on the highway as my husband and I were heading to town through the mountains. We had to roll to the side of the road as the Santa Cruz just lost all power and would not accelerate, it just died and lost power. I thought it was a fluke. My husband was driving. I asked if he had hit a button or something, he said no. Turned the ignition to off and he restarted the Santa Cruz and it turned on. On Saturday, [XXX], driving on [XXX] , heading west from Glenoma, Washington to Morton, Washington driving approx 60 mph when the Santa Cruz lost all power again driving down the highway. It was a very dangerous situation! We have logging trucks and semi trucks up and down that highway going speeds of 60 mph and more! I lost all power and had to roll to the side of the road in the Santa Cruz. Some of that stretch of highway does not even have places to pull over and some of that highway has metal guard rails as well as drop off cliffs. EXTREMELY HAZORDOUS SITUATION to have the Santa Cruz simply lose all power going down the highway! On this date the Santa Cruz had 4522 miles on it. I looked at the dash panel to see if there were any warning lights and made a point to look at the mileage. There were no warning lights. Nor warning messages. April 3rd the 2024 Santa Cruz Night was dropped of at the Korum Hyundai Service Dept. The dealership has had the vehicle for 3 weeks and states they cannot replicate the problem. There are no warning lights. Since then I have been on Hyundai Forums and have multiple people tell me the exact same situation has happened to them. They ended up finding out it was the fuel injectors. The forums also stated that the dealership could not replicate the issue when take to service department for other owners.

NHTSA complaint #11655846 — an unverified report by a vehicle owner.
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
NHTSA complaint #11645560 — an unverified report by a vehicle owner.
My coolant reservoir was so low that there was less than 8oz of coolant left in the tank. I contacted my local Hyundai dealership and had them service my Santa Cruz. The service techs at the dealership told me that there was a known issue with some of the factory coolant reservoir caps and the seal not working correctly, thus causing coolant to flow out through the cap instead of the overflow hose. They explained that the cap's o-ring at the factory is sometimes faulty. They replaced my cap and I am still monitoring for further issues. There is no TSB listed for this "known" issue. It seems that the dealership has not reported this issue.

This is my 2nd complaint re: the same issue. Loss of power during driving. Unable to accelerate. I need to pull over shut off the engine and turn it back on.
NHTSA complaint #11633032 — an unverified report by a vehicle owner.
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.
