2022 Hyundai Santa Cruz

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."

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!

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???

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. The recall for the trailer wire harness included a 15 amp fuse replacement because the wire gauge of the wire cannot handle the additional amperes. The wiring shouldn't melt or catch on fire if the proper fuse was connected to protect the circuit including the wire in the circuit. It didn't meet the National Electric Code or industry standard.

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 received a recall notification from Hyundai a couple of months ago regarding an issue with the vehicle's trailer towing system that could result in a fire. Hyundai's answer to this issue is a recommendation to kept he vehicle parked outside and away from buildings. To date they have not notified me of a fix for the issue and my vehicle, myself and my home continue to be at risk. Today I checked again and there is still no fix yet Hyundai continues to market these vehicles with this significant safety issue.
