2023 Hyundai Santa Cruz Problems

Hyundai Santa Cruz with transmission problems. 5 attempts to repair and manufacture failed to. Last time, vehicle had a sudden transmission failure while driving. Car stop responding to acceleration and transmission was not switching gears, that could had cause loss of control, especially in high-speed or high-traffic situations. Luckily it was very early in the morning, not much traffic and before (0.3 miles) from taking a high-speed interstate. Vehicle is not safe to drive and according to a research I made, other vehicles of same brand, model and year are facing same issues.

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)

driving/pulling on interstate speed only went to 20 miles per hour, no more. Pulled off and turned truck off, waited and restarted. all fine. No warning was given. Short time later engine light came on. Called and got appointment at dealers.

oil leak the oil leak has be too the dealer twice for repair each time they said it was fixed it has now has happend again for the third time in less than 306 miles could cause engine failure at highway speed and engine lockup at such speed first time it was found by dealer after third oil change approx. 15000 miles second 12000 miles later and now 306 miles latter with this time the leak was larger to to the fact that it triggerd the low oil light first two times it told to me it was oil pan gasket and a small leak which at the time made sense it not show up on the dipstick i know this was da problem on other Hyundai santa cruz models in previous years0

my 2023 Santa Cruz had 7500 miles when purchased 4/25/26. I have had issues with the screen blackening/fading which cuts of electronics; ex; safety features. This was taken in twice. Then the truck loses power. Going 55 or 75, suddenly truck drops to 20mph. Car's honk, brake & swerve not to hit us. It has been at dealers three times now for same issue. Since I've owned vehicle, it has been at dealer for 29 days tomorrow and it is still there. The truck is a death trap, always something wrong.

truck dash light would fade/blacken at which time none of safety features would work. This is an intermittent problem but seem like it has happened many times with the Santa Cruz's in general, so Hyundai was aware of problem. They don't seem to fix problems. This is a critical safety failure. No warning just happens. Had it happen to my truck about 7 times. When screen blackens, I have no safety features, can't see anything on dash, so I could get in a wreck

While driving on the highway at a speed of approx 35 mph, no traffic in front of me, I got an audile warning and the car started slowing down, and the message on the dash said EMERGENCY BRAKING, this has happened twice in the last month.

Transmission does not advance through its ranges fails to shift leaving stranded middle of intersection. Misses a whole range looses excelleration. You

Sudden Unintended Acceleration: Coming to a stop in a driveway and planning to put vehicle in to reverse, the Santa Cruz suddenly accelerated and kept accelerating ... it would not stop moving, brakes were applied continuously and forcefully, but with no effect. Vehicle crashed through shrubbery and small trees into neighbor's yard, over a retaining wall and finally crashing into neighbors parked classic car, only stopping after it nose-dived downward. We live in Rapid City, this event happened at our daughter's residence in Black Hawk, South Dakota.

Lower Average Fuel Consumption than advertised. 10mpg

The emergency brake system comes on while driving 60 - 70 miles an hour on freeway. It has happened twice. It does not happen every time I drive 60 - 70. The light comes on stating Emergency Braking and my vehicle slows down. It does not last for very long then goes away. I took it to the dealership and it did not do it for them. They kept it 3 days.

At least two separate wiring harnesses have failed on my vehicle, affecting the tail lights. My vehicle cannot pass New York State safety inspection because of this issue. Safety of myself and other drivers is at risk, especially at night, since my vehicle is not properly illuminated. Occasionally, one tail light will go out or flicker. I had one trailer harness removed under a safety recall, but I don't recall the dealership ever replacing it. Then, a couple of years later, I got a ticket for a tail light being out. Paid the dealership to replace a (possibly second) trailer wiring harness, but they got the wrong one. When they finally got the "right" one, another (possible 3rd), much more expensive harness was found to be shorted due to corrosion, prompting me to look into trading the vehicle in instead of repairing it. All harness issues in question are related to corrosion from water infiltration. The technician working on my vehicle told me that this is a common issue with Santa Cruzes and Tucson's, but only certain vehicles have been recalled (of course, mine was not on the list). My vehicle is only 3 years old. This is all after having the dealership replace a harness under the seat that was causing an issue with the audio, including safety notifications, that started within weeks of owning the vehicle. No warning lights, messages faults, or other symptoms indicated there was an issue. Self diagnostics, as accessed via Hyundai's BlueLink app, has no record of issues since the first wiring harness issues I had when I first bought the vehicle (see below). I have already filed a separate complaint regarding the harness under the seat. This is a new complaint regarding wiring harnesses, unrelated to the first underseat harness complaint.

On 04/26/23 a lamp assy-rear comb outside Qty: 1 installed 92402-K5000, was replaced due to condensation inside the taillight. On 09/22/23 both taillights, lamp assy-rear comb outside Qty: 1 installed 92401-K5000, was replaced and lamp assy-rear comb outside Qty: 1 installed 92402-K5000, were replaced due to condensation inside the taillights. Should the condensation in the taillights cause the brake and or turn signal lights to fail this could cause a serious accident! I have an appointment at 1:00 PM at my dealership Hyundai of Anderson in Anderson, SC to have both taillights inspected for the third time, tomorrow on 10/10/2023 because of condensation inside them. I might add that the condensation has occurred when there has been no rain on the vehicle and the vehicle has not been washed. My Santa Cruz is also housed in a completely enclosed garage.

1- Air bag light randomly comes on and off. 2- Today (5.20.25) I brought it to dealer. Dealer said they disconnected the sensor switch and cleaned it, then reconnected and light went off (covered under warranty). 3- I got in the truck, started it, and light was off. 4- I drove one block and airbag light came on again. 5- Returned to dealer, who asked me to leave the car with them. 6- Dealer called and said they will replace air bag (did not specify which one). I hope this solves the problem. 7- I checked a Santa Cruz forum: [XXX] and it looks like A LOT of people have the same problem. Some report it's the sensor assembly underneath the seat.

This has happened twice in the last 3 months of owning this vehicle. Both times were luckily in uncrowded slow speed areas, and I had nothing in the bed. First time was in a parking lot (without my tonneau installed), the Most recent incident happened as I was reversing out of my driveway and as I Put my Vehicle in Drive slowly moving forward my Tailgate opened Unexpectedly (with a tonneau installed). My tail Gate Did not open fast, it was its standard controlled open.

Rain sensor wiper function. On this setting, even in consistent rain, the system will jump to slow wiper intervals all the way to the fastest setting...with no change in the amount or rain hitting the windshield. It seems confused and searching for the proper speed. It becomes dangerous when it arrives at a very slow intermittent setting for rain that requires a faster interval for adequate removal for the driver to see properly.

The windshield washer spray nozzles do not provide proper coverage to clean the windshield. They spray almost directly at the very bottom of the windshield while at rest, and it's even worse when at speed. I had the dealer check it out. They originally told me they adjusted the spray nozzles, but when I picked up the vehicle, the problem was still there. So I brought the vehicle back to the dealership. This time, they told me that these nozzles are not adjustable. The wipers aren't able to clean the windshield, so this causes significant visibility issues; especially with road salt or light rains. And at night, it's very difficult to see where I'm driving.

The contact owns a 2023 Hyundai Santa Cruz. The contact stated that while hauling a trailer and attempting to accelerate at various speeds, the vehicle was bouncing, and the tires was losing traction before being able to accelerate. The contact stated that the vehicle failed to raise and lower as the shock absorbers needed to perform. The vehicle was taken to the dealer to be diagnosed, and it was determined that the rear shocks had failed to allow the vehicle to self-level. The rear shocks were replaced; however, the failure persisted. The contact reported the persistence of the failure and was advised to go to another dealer, Greg Hubler Hyundai (6200 W Hometown Blvd, Muncie, IN 47304) who also replaced the rear struts. The manufacturer was informed of the failure and opened a case. The failure mileage was approximately 7,000.

Tire size Michelin 245/50. R20. Multiple tire flats right rear vehicle has 8368 miles. Last flat was puncture in sidewall requiring replacement of tire. Suspect tire rubber faulty as appears odd color and extremely difficult to clean also has odor or odd smell when cleaning. All flats were displayed on the pressure dash warning it is unknown to me why multiple flats could be a malfunction of all wheel drive system rt wheel turning different from rest of wheels?

Driver's seat power height adjustment does not work. Brought it to the dealership and they claimed they verified the issue and it was because of something I had under the seat. They claimed to have corrected it, and verified operation, but it still doesn't work. When confronted about it, the service manager now insists it's the switch that's the problem, and he is ordering a new one. This issue prevents me from adjusting the height of my seat, so I sit so high that the rest view mirror blocks my field of view. This remains unresolved as of 10/26/22.
