2023 Hyundai Santa Cruz Complaints

ELECTRICAL SYSTEM — Filed 06/05/2026

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

SERVICE BRAKES,FUEL/PROPULSION SYSTEM — Filed 04/22/2026

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.

ELECTRICAL SYSTEM,EXTERIOR LIGHTING — Filed 03/07/2025

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.

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.

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.
