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.

On [XXX], I went out to start my 2023 Hyundai Santa Cruz (SC) to leave work to go home. It was difficult to start, however, it started. As I entered [XXX] , i was nearly rear ended by another car, because my SC lost all acceleration. I turned on my hazards for SAFETY and then began to try to accelerate again and was only able to get up to 45 MPH and then was turning 4,000 RPM. I limped my SC home where I had it towed to a local Hyundai dealer as it has roughly 38,000 miles. The dealership had it for 3 days, but couldn't duplicate the issue, so no repairs were done. The Hyundai Santa Cruz has KNOWN transmission issues and the fact I was nearly rear ended could've caused a nasty wreck, resulting in more damage or even a fatality. I reported the issue to Hyundai customer service on the 11th of September (Case #[XXX]). However, in the response from Hyundai, basically saying they "experiencing a high e-mail volume" and responses may be delayed. As of 9/13/2025, I have not received a call or email from Hyundai's customer service. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The contact owned a 2023 Hyundai Santa Cruz. The contact stated that while exiting the vehicle to go into a store, he looked back and noticed the vehicle was on fire. No warning lights illuminated. The contact mentioned he noticed the fire was coming from the rear driver's side quarter panel. The contact called 911. No injuries were sustained. No medical attention was required. A police report was not filed. The fire department extinguished the fire. The vehicle was taken to a savage yard, and the insurance will then have the vehicle towed to a body shop. The vehicle was not repaired. The manufacturer was notified of the failure, and they informed the contact that they would inspect the vehicle, and they also offered to buy back the vehicle. Recently, he got an email informing him that they are not going to buy back the vehicle. The failure mileage was 18,000.

car flashes transmission low fluid and gives a code of p193b-79. when trans downshifts upshifts will not happened. to clear the problem you have to turn car off and on , and then normal operation resumes, but shifting is now slower. and sluggish. this is the second transmission to have this problem. Seem hyundai has not fixed it from the 2022 recall.

1- Air bag light randomly comes on and off. 2- Today (5.20.25) I brought it to dealer. Dealer said they disconnected the sensor switch and cleaned it, then reconnected and light went off (covered under warranty). 3- I got in the truck, started it, and light was off. 4- I drove one block and airbag light came on again. 5- Returned to dealer, who asked me to leave the car with them. 6- Dealer called and said they will replace air bag (did not specify which one). I hope this solves the problem. 7- I checked a Santa Cruz forum: [XXX] and it looks like A LOT of people have the same problem. Some report it's the sensor assembly underneath the seat.

Received error code P030300 and the third cylinder fuel injector had to be replaced. There is approximately 36000 miles on the vehicle.

Oil filter cap oil leak problem. Typical problem with this vehicles that require attention. These defective oil leak caps are a safety and environmental concern. The engine almost starved of oil while driving on the highway. Manufacturer has been contacted and are not proactive in taking care of this defect.

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.

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 emergency brake system comes on while driving 60 - 70 miles an hour on freeway. It has happened twice. It does not happen every time I drive 60 - 70. The light comes on stating Emergency Braking and my vehicle slows down. It does not last for very long then goes away. I took it to the dealership and it did not do it for them. They kept it 3 days.

Lower Average Fuel Consumption than advertised. 10mpg

I am experiencing shuddering when accelerating from stop.

This has happened twice in the last 3 months of owning this vehicle. Both times were luckily in uncrowded slow speed areas, and I had nothing in the bed. First time was in a parking lot (without my tonneau installed), the Most recent incident happened as I was reversing out of my driveway and as I Put my Vehicle in Drive slowly moving forward my Tailgate opened Unexpectedly (with a tonneau installed). My tail Gate Did not open fast, it was its standard controlled open.

My coolant reservoir was so low that there was less than 8oz of coolant left in the tank. I contacted my local Hyundai dealership and had them service my Santa Cruz. The service techs at the dealership told me that there was a known issue with some of the factory coolant reservoir caps and the seal not working correctly, thus causing coolant to flow out through the cap instead of the overflow hose. They explained that the cap's o-ring at the factory is sometimes faulty. They replaced my cap and I am still monitoring for further issues. There is no TSB listed for this "known" issue. It seems that the dealership has not reported this issue.

This is my 2nd complaint re: the same issue. Loss of power during driving. Unable to accelerate. I need to pull over shut off the engine and turn it back on.

Vehice experienced FULL power loss several times. Truck taken to dealership and stated no problem found. Incident happened again a week later. Determined wires can become lose from battery terminals for no reason.

My 2023 Hyundai Santa Cruz, which I bought new, has gone into limp mode twice in 8 months, losing power while I was driving and letting me go no faster than 25 MPH. The first time, in April 2024, I was on [XXX] in Hartford CT. I called 911 because I was certain I would be hit by a car. There was no warning lights to indicate a problem. I was able to get off the highway and had it towed to Meriden Hyundai in Meriden CT. They said they could find nothing wrong. On [XXX], my vehicle went into limp mode again. I was able to drive it to the same dealer since I work nearby. Again, they say they can't find the cause. I have been without a vehicle since then. The car is a danger to drive, and Hyundai has not resolved the matter, though I've been in contact with corporate representatives. Limp mode has caused many crashed across the country. It is designed to protect a car from a mechanical problem - but the system itself puts drivers at great risk. My hope is the NTSB will investigate my case and this national problem before more people are injured or killed.
