2022 Hyundai Santa Cruz: sudden loss of power

Filed Sep 27, 2026 · Driver assistance, Electrical · NH

I have had one Transmission and the tow hitch wiring harness replaced once from recalls. The tow hitch wiring harness is failing and all the warning lights are failing. The transmission is slipping upon takeoff and will rev at elevated RMS on the highway at times. When in reverse it will still move forward at times and on a hill it rolls back. The breaks have slammed on (for no reason) a couple of times while on the highway. It has also lost power. No check engine lights are on at this time. The warning lights for wiring harness are on at all times. I had it looked at last week and I had to pay $400.00 but they never drove it and said the wiring harness is no longer their responsibility.

In approximately late 2024, at just under 30,000 miles, the vehicle lost motive power while driving on the interstate. Multiple warning lights illuminated and the vehicle lost drive shortly afterward, leaving me unable to accelerate in traffic. The vehicle was then serviced under Recall 236 (the federal safety agency 22V‑746) for the 8-speed dual-clutch transmission high-pressure oil pump. The remedy performed was a transmission control unit software update only; the transmission was not replaced. I do not have the exact dates and am reporting these as approximate. The vehicle now has approximately 99,700 miles. It has developed hesitation and dragging on drive-off within the first half mile of every trip and at low speed in town, resolving once the transmission is warm, with no check engine light or warning lamp. The selling dealer had the vehicle approximately 35 days across two repair orders without diagnosing the condition. The repairs performed were a cylinder 3 spark plug/oil repair and dropping and cleaning the fuel tank, neither of which resolved the complaint. I have run non-ethanol fuel exclusively since the vehicle was returned and the condition is unchanged. I am taking the vehicle to a different Hyundai dealer and have opened a case with Hyundai. I am filing this report because the software-only remedy may not be adequate for this transmission. Roughly two years and 70,000 miles after that repair, the same transmission is again showing drivability problems, and other owners may experience the same loss of power.

Vehicle in the middle of turning in to a hazardous highway lost power and then began to drive sluggish at 20 miles per hour skipping. It acted like the fuel injectors were not allowing it to get fuel. After having some one check it is exactly what was wrong.. It he vehicle had not caught up I would be dead as an oncoming vehicle did not realize the care was not moving.

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.

Loss of power from the engine while accelerating from a stop in heavy traffic. Car began shaking and sputtering with intermittent spurts of power, unable to exceed 10 mph on narrow bridge. Pulled over and the vehicle smelled heavily of gasoline near the engine. This issue is the Third instance of my engine sputtering and losing power. The first instance, injectors 2 & 4 were replaced. The second instance Injector 3 was replaced. I followed dealer recommendations and only used top tier gas from busy stations, and manufacturer technician recommended techron additive every 1000 miles. There have been two additional instances where the engine sputtered but regained power, with the dealer unable to replicate the issue.

My 2022 Santa Cruz Limited Edition keeps losing power intermittently. No accident yet but very risky to drive.

I was driving on the freeway at 65mph and experienced a sudden loss of power. I depressed the gas pedal but the car would not accelerate past 45 mph. I had to drive all the way home with my hazard lights on. There were no lights on the dashboard to signify a problem. This happened several times. I took it into the Hyundai Service center and they could not replicate the problem. It happened again. and again. and again. finally got an error "possible condition with your engine control module". Took it into the dealer and after they drove it around for hundreds of miles they said they were able to recreate the problem, pulls some codes and relaced the fuel injection pump. It happened again. and again. and again. I took it back to the Hyundai Service center. They could not re-create the issue. They told me to use Chevron gas only and added an additive to the car. It worked for a while. Then it happened again. And again. I took it to a different Hyundai Service Center. They were not able to re-create the problem. Apparently, every time I drive the car, after 5-10 minutes on the street roads, the car fails to accelerate and I have to pull over, stop the car, and then re-start it. Re-starting it seems to clear the issue. I am driving in SMART mode and my car is at 39000 miles. Every time I take it to the service center, they can not re-create the issue. This is outrageous. Do I need to get into a car accident in order to bring legal action to Hyundai for not fixing this loss of power/failure to accelerate issue? Worst part is, the first Hyundai service center went out of business and I can not get any of the maintenance records for the fuel pump replacement.
