The contact owns a 2022 Hyundai Santa Cruz. The contact stated that while attempting to accelerate, the vehicle failed to respond. The contact stated that after letting up off the accelerator pedal, the engine revved up and the vehicle lunged forward. There was no warning light illuminated. The contact stated that the instrument panel background lighting was very dim for all the display functionality. The local dealer was contacted and informed that the failure had occurred intermittently, and while driving at various speeds. The dealer suggested that the vehicle be taken in to be diagnosed; however, the vehicle was not yet diagnosed or repaired. The manufacturer was made aware of the failure and opened a case. The approximate failure mileage was 37,000.
2022 Santa Cruz 764 miles. Washed vehicle April 1st with hose, water & soap bubbles in grill of DRL. I was told that its a lens cover & not the LED DRL, but it collects and holds water & soap. I can't clean in there. Field service engineer came out, deamed normal by Hyundai, grill & lens are not sealed. Unacceptable, water collecting by electrical component. Can't get behind lens cover to clean. Eventually im going to have a film in there, and DRL won't work as they should. If soap and water get in now, what happens during winter when it gets road spray from rock salt melting snow and ice turn things to a slush? Who's going to clean that? What happens when the water turns to ice? I mentioned windshield gets foggy and has to be cleaned inside, I was told to use my defroster to clean it. There is no defroster in grill. …
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. …
"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. …
I read the complaint someone made about a vehicle fire in their garage with the 2023 Hyundai Santa Cruz. My vehicle is wired incorrectly and the fused circuit protect doesn't protect the circuit. The Blower relay is rated for 35 amps, but it has a 40 amp multi-fuse protecting it. In addition to that, the low current coil that turns on/off the relay is also connected to the 40 amp multi-fuse. The E-CVVT relay is also a 35 amp relay. It has an incorrect mutifuse of 50 amps protecting the relay. The relay is the same type as the blower relay. The low current coil is protect by a 10 amp fuse unlike the incorrect 40 amps for the blower relay coil. The wire gauge of the wire going to the PCM and motor doesn't seem to handle this current if the Blower motor or E-CVVT motor were to seize and draw more current. …
I was driving on the highway (55mph) with my two children in the backseat. My vehicle started slowing down quickly even with my foot on the gas. There was no warning, no lights on the dash lit up warning me there was anything wrong with the car. The rpm's we're going up but it was like there was no power to the car. I got off the highway onto a side road as fast as I could do I wouldn't get hit. Then I pulled off to the side of the road. I put it in park and turned it off. I tried to turn it back on and it would start. After a second attempt it turned on but was really rough and felt like it would stall. I used blue link to call for a tow truck. Then I called the dealership to tell them since I've only had the car for 9 months. I tried to turn the car back on and the dash said battery discharging due to electrical and it turned off before I could read the last word. …
My vehicles screen flashed a brief notification that I needed to update my Nav software. Afterwards the vehicle began flashing a distracting audible and visual alert of random road hazards...caution road is slippery...or rough...or whatever....literally EVERY FIVE SECONDS. There is no way to turn off the audible sound or alert. You can dismiss it, but that only prompts it to return immediately. Other owners report that the dealerships have no fix. Hyundai has pulled down access to the software update. A factory reset is reported not to work. The only way to stop it is to pull the fuse disabling the whole climate control system and infotainment/nav system. It has been since ~May 4th. This is just unacceptable and presents an unsafe distraction. Hyundai has likely been hacked but is not admitting it.

I was accelerating onto the interstate in a busy high speed area and suddenly there was no communication to my transmission. I went from 58 miles an hour to 20mph is a matter of seconds barely avoiding causing a several car pile up. I had vehicle towed to 2 different dealer service departments to no avail. I was told that there was no code and the problem could not be duplicated. However there is a recall for a similar issue. I was told my vin number didn't fall within that recall. The vehicle has been in the shop for several issues in the 6 short months I've owned it most appear to be related to electrical issues. I've made several attempts to resolve the issue through Hyundai with no resolution.
I have had one Transmission and the tow hitch wiring harness replaced once from recalls. The tow hitch wiring harness is failing and all the warning lights are failing. The transmission is slipping upon takeoff and will rev at elevated RMS on the highway at times. When in reverse it will still move forward at times and on a hill it rolls back. The breaks have slammed on (for no reason) a couple of times while on the highway. It has also lost power. No check engine lights are on at this time. The warning lights for wiring harness are on at all times. I had it looked at last week and I had to pay $400.00 but they never drove it and said the wiring harness is no longer their responsibility.
