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.

I’m concerned about the power brakes I’ve received these faults a few times. DTC DTC System DTC Sub System C184987 CHASSIS LKAS Also there are reports online that other owners have experienced this issue with their Santa Cruz’s Some reporting dealers lack of concern. Diagnostics History My vehicle Last Reported Original Date Mileage Status DTC DTC System DTC Sub System 02/23/26 02/20/26 572 C184987 CHASSIS LKAS This refers to the vacuum pump that controls the power brakes. When applied the brake pedal becomes firm. When this code is triggered, your vehicle will likely illuminate warning lights on your dashboard, such as the ABS and ESC warning lights. You might experience a change in how the brake pedal feels or a temporary deactivation of cruise control or stability features. The Diagnostic Trouble Code (DTC) C184987 is a chassis-specific trouble code that typically points to a fault in the vehicle's braking or stability control system.
NHTSA complaint #11751347 — an unverified report by a vehicle owner.
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
NHTSA complaint #11749492 — an unverified report by a vehicle owner.
While driving my vehicle on a two-lane highway, I experienced multiple sequential electronic system failures (including the vehicle no longer detecting the smart key), and all electronic systems on the car became inoperative. I lost all instrumentation, including my speedometer and tachometer. At the same time, I also experienced a loss of motive power, and the engine of the vehicle began running extremely erratically before completely cutting off. I attempted to make a safe stop on the side of the road, but after doing so, could not restart the vehicle. The electrical systems of the vehicle continued to behave erratically, and the engine would not restart. I contacted roadside assistance, but they were unable to start the vehicle as well. It was towed to my local Hyundai dealership, but instead of expressing any genuine concern for the significant risk I endured while being placed In harm's way, they refused to fully diagnose the vehicle, and instead accused me of "jumping in reverse," even though I did no such thing (and don't even know what that means). The dealership has no evidence to suggest any such event took place, and simply wants me to pay over $1,800 for replacement of the battery connection terminals, despite being in-warranty. Obviously, the vehicle was already running – there is no way that the dealership's false allegations could possibly be correct. I contacted Hyundai Motor America and was assigned a caseworker, but they were not interested in finding a resolution, and unable to compel the servicing dealership to perform a full diagnostic or provide warranty service. Feeling that I was running out of options for the vehicle to be properly diagnosed, I contacted the dealership where I purchased the car, and provided the photographic evidence & service documentation required. They agreed that there's no way that I could have created this issue, and that further investigation is warranted, but HMA only cares about money – not my or my family's safety.

"The 8-speed Dual Clutch Transmission and engine (Cylinder 4) failed on my 2022 Hyundai Santa Cruz SEL Premium AWD with 37,780 miles. Both components are available for inspection upon request. While merging onto the highway in Sport Mode, the vehicle experienced violent shuddering and noise so severe I believed I had multiple flat tires simultaneously — specifically both front and rear passenger side tires. I immediately activated hazard lights and exited the highway. I was unable to safely operate the vehicle. Other drivers on the highway were also put at risk by my sudden need to exit. The dealer has NOT been able to reproduce or confirm the transmission issue despite multiple documented visits over the past year. However, AutoZone confirmed diagnostic code P0304 Cylinder 4 Misfire Detected on March 19, 2026 via OBD-II scan. The vehicle has been inspected multiple times by the Hyundai dealership over the past year. Hyundai Motor America has an open case on this vehicle and has escalated it to their buyback department. The Check Engine Light illuminated during the highway incident then self-cleared. Transmission slipping, shuddering at low speeds, high RPMs at low vehicle speeds, and failure to shift properly have been reported to the dealer for over one year. This vehicle contains the identical DCT transmission covered under Hyundai Recall 236 but my VIN was excluded despite identical symptoms. Backup camera has also failed twice — a federally mandated safety device."

I was driving on a highway at 55mph at night today 3/1/2026 and all of a sudden the headlights, instrumentation lights, and computer display went out, very scary, the all turned back on about 1.5 seconds later.
NHTSA complaint #11721312 — an unverified report by a vehicle owner.
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.

Backup camera doesn't work 50% of the time (black screen) when in reverse OR when it works stays on after being put into drive. Has happened numerous times (over 20). Took to dealer, they said if there's no error code, they can't do anything. (Of course it worked fine the 15min I was at the dealer).
NHTSA complaint #11629181 — an unverified report by a vehicle owner.
While driving at highway speeds with Smart Cruise Control set during the day I put on sunglasses and the driver attention system turned off the system 6 seconds later. I repeated this event set several times at various speeds and driving conditions with the same 6 second failure result. I made the dealership aware of this and verified it with them in the vehicle. Apparently, system uses an IR camera to determine driver attention level via eye contact and does not work with most sunglasses. This seems to be a safety issue the dealership (or the manufacturer) should be the making the general public aware of.

This vehicle was subject to a recall regarding a fire hazard due to faulty OEM wiring harnesses provided with the towing/hitch package. The recall was because of fire risk by the harness and it was recommended the vehicle be parked outside. A repair has not yet been made available by the manufacturer.

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.

1.Spring 2023 Received a Recall on tow hitch wiring package (may catch on fire)... No solution yet! I was experiencing transmission problems around same time. 2. My Hyundai App warns of transmission problem on 07/22/2023. Took my (19 month old) 2022 Santa Cruz to Preston Hyundai 07/24/2023. Earliest appointment available was scheduled for 08/09/2023 (16 days waiting period). 3. 08/09/2023, at Preston Hyundai, says they must order a new transmission and refuses to give me my truck back claiming it is UNSAFE to Drive (even though I drove it 16 days (over 400 miles) waiting for my service appointment!). Truck has remained at Preston Hyundai since 08/09/2023 and replacement transmission ETA is 10/24/2023, making total time in dealership 76 days to date (or 92 days since being notified on my Hyundai appof transmission problem! Truck has not moved or been started since 08/24/2023. 4. Back on 07/22/2023, I attempted to program Navigation system with "vacation address" but Nav System displayed prompt that Nav it needed a map update. I cleared the "OK" prompt off the display but I started getting "Check Engine" dummy light appearing and other dummy lights appearing! Also my tachometer gauge (also is the right turn signal mirror camera), quit working and started beeping every 10 seconds or so. 5. On 07/24/2023, at Preston Service Dept., I ask them to update Nav System. I was told that it takes too long and they won't do it! (lacking personnel and time and I should do it myself. I researched "How To" and discovered many warnings from owners that their vehicles computer system got messed up attempting the map update. I've been communicating with Hyundai headquarters who suggested I inquire about the "BuyBack" Program at my Dealership! I did inquire on 10/10/2023 and they've never heard of it, but evaluated my truck and offered me $27,000 for my 20 month old truck, leaving me a $15,000 expense for a new 2024 Santa Cruze. 6. I've now contacted a "Lemon Law" Law Firm!
NHTSA complaint #11549354 — an unverified report by a vehicle owner.
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.

This is an ongoing problem that neither the local dealership of the manufacturer seems willing or able to correct --- or even consider it a safety issue. DRIVER DISTRACTION IS A SAFETY ISSUE! not to mention the tension and stress this is causing me...while I am unable to enjoy my new 2022 Santa Cruz: For no apparent reason, the vehicle dashboard started giving me flashing visual and sound alerts that alternate between "bumpy road ahead" and "slippery road ahead" while driving. This freaked me out not knowing the problem. I could not get the dealership to even answer the phone! The alerts still continuously flash visually and intermittently sound the distressing high-pitched alert; They block the legitimate alerts on the right side of the dash for lane-keeping, passing other vehicles, and whatever other alerts come up on the right side of the dash. May 18, 2023 the Orange Park dealership tried a recommended software download that worked for only a day. They said Hyundai is aware of the problem they have no fix! They tell me other vehicles have the same problem and they can't figure it out! They tell me there is no way to even turn off the SOUND!! In April I was provided a Hyundai Case #21475812, asked for acceleration...last attempt May 24, 2023 ... still no resolution and no follow-up nor indication of concern. Case number is nonexistent on the My Hyundai website. How are they allowed to falsely advertise bumper to bumper warranty coverage???
NHTSA complaint #11527001 — an unverified report by a vehicle owner.
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
