2022 HYUNDAI SANTA CRUZ Fuel/propulsion System Problems

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

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

I purchased my 2022 Hyundai Santa Cruz new from Hallmark Hyundai in Tennessee. Ever since the purchase of my Hyundai Santa Cruz I have had issues with fuel injectors. I have had two fuel injector failures that had to be covered under warranty, the last fuel injector that failed under warranty was on cylinder 3 and was replaced a year ago at Coastal Hyundai in Melbourne, Florida. Three weeks ago, the fuel injector failed again on cylinder 3 and isn’t covered under warranty. This makes the third fuel injector (two on the same cylinder) to have failed in the three years of owning my vehicle. With less than 80,000 miles on it. Hyundai knows it’s a problem as they recently changed their service bulletin mandating all four fuel injectors to be replaced with an upgraded part. However they won’t cover the charges and I’m on the hook for the bill. Also, the new upgrade kit is on back order. I’ve been given three dates know for when it was supposed to be in stock, but they moved the date out again to May 25 and they’re not confident that it will be here then. There needs to be a recall ordered for the fuel injector replacement as Hyundai knows it’s a problem. There are over 3,000 customers waiting across the country for this new upgraded part.

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.

On multiple occasions the car had trouble starting and while on the road it would idle like it was struggling. My concern was the car dying on me while on the road and causing an accident for myself and the other drivers or pedestrians. The manufacturer hasn't inspected it nor has it been confirmed by the dealer. I haven't had any warning and they first started to appear in the beginning of 2024. I just recently read the fuel injectors are the cause of this and so far there has not been any recall by the manufacturer

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 began shaking on the interstate and showing a check engine light on the dash. After pulling off the road to a nearby auto parts store, the ODB reader showed a DTC of P0301, which is a misfiring cylinder. A independent mechanic across the street from the auto parts store diagnosed the issue as a leaking fuel injector, but in order to get the repair cost covered, the vehicle had to be towed to a Hyundai dealership. The dealership did not have any loaner vehicles to offer and estimated 1-2 weeks to even officially diagnose the vehicle themselves. 2 weeks later, the dealership is estimating another 2-3 weeks or more, and Hyundai corporate will not approve any reimbursement for the out-of-pocket costs of hotel, towing, Uber, and rental until diagnosis AND repair is complete, which could be an unknown period of time.

Just had the fuel induction serviced day prior to issue. Started car normally. Went to accelerate and no power. Car crawled forward and would not go past 25mph at a slow crawl. Stopped turned of engine and restarted. System to be working normally.

I was trying to accelerate with pushing the gas pedal and the truck would not go any faster than 22 mph. This went on for 15 minutes until the truck was turned off and restarted. It seemed to be corrected with turning the vehicle off. No engine warning lights came on and the vehicle was in drive the whole time. The concern was not being able to accelerate on the on-ramp to the main highway. The vehicle has not been inspected by anyone at this time. The problem could not be reproduced after it occurred today.

August 16th, 2023 - Roughly 10:30 am Started car using Push-To-Start, car coughed a few times upon startup. Was about 74 degrees, not too hot or too cold. (This has happened before, not totally abnormal for it to cough on startup.) Loaded up the kid, our luggage, and left. Car was running about 4-5 minutes before putting it in drive. Drove out of the neighborhood street pretty normally, went to our stop sign, turned left. Car struggled up hill, appeared to be revving, but the RPMs and the speed did not reflect the amount of noise the car was making. Stopped at another stop sign, turned right, car WOULD NOT accelerate faster than 25ish mph. I put the pedal to the floor to try to bring up the speed, the SMART mode indicator was turning red (indicating bad gas mileage) but it was not accelerating or moving any further. Pulled into someone's driveway to get off the road. Stopped the car, put it in park, then put it in reverse, drove out of the driveway, put it back in drive. Car continued to not accelerate. Unable to get RPMs past 3k and speed past 25ish mph. Got it home without incident. Had dealership tow car as I was unwilling to drive it on an 70 mph road to get it to the dealer. Dealership and Hyundai corporate reject that anything occurred due to there being no computer indicator indicating there was an issue. They believe I had the car in manual mode. I discussed with them that 1) This was very unlikely, as I shifted back into drive more than once and 2) my RPMs would have been increasing if I was accelerating but simply not shifting. I went online and found out this is a widespread issue - I am not the only one reporting this problem.

Fuel tank opening actuator is getting stuck and fuel tank cannot be open or closed properly advice from Hyundai is to drive with open Tank that I do not consider safe

When accelerating from a complete stop the transmission skips within the first few RPMs. This also happens when coming to a complete stop. It feels like a stall or a stutter. Also does it when put into reverse.

Hyundai Santa Cruz's have been having transmission problems that cause you to lose power while driving. This is a dangerous situation, the car will not accelerate and you are left in the middle of the road with no power to maneuver out of danger. I had to coast to the side of the road to get out of traffic. Hyundai announced a recall but Hyundai states that there is no fix at this time. Dealers are not able to perform any work as Hyundai doesn't have a plan to correct this dangerous situation.

When pulling out onto a major HWY, the vehicle lost power. Vehicle acted like it was in "neutral" but engine wouldn't rev when pressing gas and rpm was bottomed out. Vehicle then would not shift out correctly.

Problem 1 - The vehicle has stalled twice at low speed (less than 5 mph). Both times I had just pulled away from a parking space, coasting (or slowing) before a STOP sign and the vehicle dies. It beeps loudly, says shift to Neutral and restart. It did restart both times. This happened both times while being in SMART mode. I drove it about a month in NORMAL mode between stalls and the issue did not happen. Maybe a coincidence, maybe not. I have had the Santa Cruz less than 2 months. Problem 2 - While accelerating away from a stop, it seems the vehicle revs and does not accelerate, almost like it is not in gear.

Purchase the 2022 Hyundai Santa Cruz with under 30 miles. At 329 miles was driving on a road going about 40mph and the big Check Forward Safety System warning light came on inside the tachometer screen. The car started to slow down, and wasn't responding to the gas pedal. Then the dashboard had the following lights on: Check engine, front collision, downhill, EPB, Auto hold, traction control. Also the triangle with explanation point was on below the tachometer with a red bubble with the number 3 inside of it. Luckily I was able to roll into a parking lot. As the car was stopped and still running, without gas pedal working, the engine was revving between 1400-1600 rpms and the engine sounded very bad. The diagnosis light from the check engine light show up as POWERTRAIN - DTC - PO65312 Turned the car off and let it sit for a minute before starting again and only check engine light was on. Was able to drive home a couple minutes away and had the car towed to the dealership. Dealership had the car for almost 2 weeks and the paperwork just shows that they weren't able to duplicate the issue so they cleared the code. The service manager on the phone said they updated the system and said it was most likely an issue with the front radar system. Fast forward now the car has 3422 miles on it. Car was in the garage and I started it. It was running for under a minute and the same exact issue had happened as the first time. Same dash lights, same engine code. Had car towed same day to Hyundai dealer. A couple days later I was told the issue was the throttle body assembly. They replaced the throttle body, checked all the connections and cleared the code. Fast forward again to 4134 miles on the car. Was traveling on a parkway going about 65mph and the same exact issue happened again. Luckily I was able to get over and exit the highway all without the gas pedal not working. Three times with the same issue after being fixed twice is unacceptable.
