2023 Hyundai Santa Cruz

The push-to-open fuel filler door repeatedly failed to release, preventing refueling. The door locks through an electronic actuator tied to the central locking system, and there is no interior lever or owner-accessible manual override. Beginning in August 2026, the door intermittently failed to open when pushed with the vehicle off and all doors unlocked. Cycling lock/unlock on the key fob while pressing the door sometimes freed it after several minutes; other times it would not open at all. No warning lamps or messages preceded the failures. A door that will not release means the vehicle cannot be refueled, which can strand the driver or cause a loss of motive power in traffic. Owners of other 2022-2023 Santa Cruz vehicles report the same failure online, including at least one tow after an owner could not refuel. An authorized Hyundai dealer inspected the vehicle twice. On 08/29/2026 (24,410 miles) the dealer could not reproduce the concern and lubricated the latch pins. The failure returned within days. On 09/09/2026 (24,520 miles) the dealer confirmed the concern, found the electronic release motor had failed and the door housing assembly seized, and replaced the housing (part 81595-K5500) under the 5-year/60,000-mile warranty, documenting the repair with photos per Hyundai's warranty policy. The failed component remained with the dealer; both repair orders are available on request. Hyundai already addresses this failure on the related Tucson: TSB 25-BE-021H covers the same fuel filler door release actuator on 2022-2024 models, and its official repair video is titled for both the Tucson and Santa Cruz, indicating a shared component and known failure mode. No Santa Cruz bulletin or remedy has been published. I ask NHTSA to track this as a defect trend.

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

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.

The system that failed was electrical near or in the Tow Hitch which caused the vehicle fire. Vehicle is available for inspection at Auto Body Evolution Essex MD. The car caught fire in the back of the vehicle while parked in Owner's driveway and engine off. Neighbor pounded on Owner's door at 6:50 am. yelling for the residents to open the door that their vehicle was on fire in their driveway. Fire was dangerously close to the gas cap; parked vehicle was close to the owner's house, two boats in the driveway, and neighbor's house. After the incident, owner googled for any issues with Santa Cruz's. It was then and only then we learned that this vehicle had a fire recall on the Tow Hitch. We NEVER received a recall notice. In fact, we had this vehicle at the dealership approximately 6 weeks ago for another recall issue, thermostat, and the dealership NEVER checked for any additional recalls. Police and Fire Department were called to the scene by using 911. Officer Irwin who arrived on scene, Badge #6560, Police Report #[XXX], had to use his bully stick to bust the window to use a fire extinguisher before the fire department arrived. The car would not unlock and the windows would not operate. If we had been in the vehicle when the fire erupted or any other passengers in the vehicle, we would not have been able to get out of the car due to the electrical fire effecting the operation of the window and doors if the doors were locked.

11/14, 2023 Drove about 2-3 miles when all warning lights on the dash came on like a Christmas tree. I was coming to a 4 way stop, both roads were 55 mph speed limits. There was a car behind me and another coming to a stop from the left. I wanted to get across the intersection to pull over and assess the situation. While trying to get across the intersection there was no response to the throttle pedal, ended up idling through the intersection at 4 mph. After getting across I pulled over and turned the truck off, let it sit for maybe a minute or so. Then I restarted and the only warning light that stayed on was the service engine warning light. The throttle showed response at that time, I started driving slowly and eventually felt it was ok to gain speed. Was able to drive at posted speed limits. 11/1582023 I took truck to Hyundai service department. 11/17/2023 Hyundai service advisor called and stated the tech support line told them to try replacing the wire harness because of erratic readings. The harness was on backorder until 11/27/23. 12/4/2023 Service advisor told me the harness was now on national backorder until 12/7/23. Again he said he will contact me when the part comes in. Truck went into service on Nov 15, 2023 and now Dec 17, 2023 tech line suggested wire harness to be replaced is still not available.

Rough Idle, Loss of engine power, and cylinder misfire on 2023 Santa Cruize Limited approx. 26,700 miles(currently) purchased new 04-28-2023 at Hyundai in North Knoxville, TN. Vehicle is stored in insulated garage at all times when not in use. 1) Approx. 2k-4k mi vehicle was having rough idling upon start up & have to sit, wait several minutes to allow vehicle ample time to warm up like a cold natured, carbureted engine. Dealer was unable to replicate at vehicle service intervals(60 miles away from home). 2) During Oct 23 approx. 24k-25k experienced 3 occurrences of loss of power while accelerating to merge into traffic, toggled through drive modes, put in manual, then back. Power came back each time. 3) 11/12/2023 Second start of the day, immediately upon startup was running extremely rough in idle, very little response. Check engine light is on, made video of issue & documented miles: 26,121. Turned off, then back on, issue was resolved. 4) 11/15/2023 26,373 miles: Second start of the day, same issue described in "#3", extremely rough idle, check engine light, & sounds coming from tailpipe that can be identified as "drone". Opened hood, inspected intake components, removed engine cover to check for burned or odd colored wires to injectors & coil packs, but no evidence of fouled or damaged wires. Turned vehicle off, then back on & the issue cleared. Contacted dealer where purchased, advised to bring vehicle in for diagnostic evaluation. 5) 11/16/2023 26,606 miles: Again, second start of the day, check engine light, extremely rough idle & louder "drone" sound. Left vehicle in the state that it was in, drove to dealer from work(25miles away) to be diagnosed while issues were occurring. While driving vehicle had very little power, experienced odor while driving, shudder, & jolting during accelerations. Diagnostic eval. revealed misfire in cylinder #3, dealer inspected coil packs, wires, & removed spark plug. Currently being serviced, issued loaner by dealer.

Car will not start properly and shuts itself off after which a strong odor of burning plastic is present in the vehicle. It will periodically do this almost once a day if not every other day. I have taken it in to the dealer 4 times last time they had my car for two weeks and could not replicate porblem because they only drive it 5 miles and it will not happen unless vehicle is being daily driven. I have found numerous other owners with the same complaint. Hyundai will not authorize shop to work on car and advises them to release it to me each time. They only attempted to fix once and gave it back to me all over times. The car is at the dealer again and they will not work on it till october to try to find the problem again. I will not drive this car due to risk of car deciding to turn it self off or start on fire due to whatever is melting when this happenns car is still at red mcombs northwest as of today.

The most major problem that occurred on 2-3 different occasions is that the emergency braking system activated for no reason on one occasion, almost causing a Rear end collision with a person behind me. No one to my sides, and in front of me on all of the occasions. Headlights on the automatic, setting on a bright sunny day, will turn off and on no change in lighting which annoys other drivers because they think I’m flashing them. After starting the car in Drive the first time I break and then go to accelerate there’s a delay in the acceleration. as well as other times while driving. Today, the back up camera didn’t shut off when shifting into drive like it normally does it didn’t go off until I went into parking pushed the radio button. I’m pretty sure it’s a computer issue

On May 1, 2023 I pulled my 2023 Hyundai Santa Cruz into my garage at about 5pm and fyi It was blustery outside and had been raining & snowing all day. At about 5:15 pm I heard a loud bang followed by another. I looked out the back door and saw that the whole garage was completely engulfed in flames. My garage is attached to my home and the fire spread fast especially with 40 to 50 mile per hour winds feeding it. The only thing we could do was to get out with with our 2 dogs and nothing else. The consensus among fire professionals are that my vehicle started the fire. So here I sit with absolutely nothing!
