There are 8 owner-reported engine complaints for the 2023 Hyundai Santa Cruzin NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
oil leak the oil leak has be too the dealer twice for repair each time they said it was fixed it has now has happend again for the third time in less than 306 miles could cause engine failure at highway speed and engine lockup at such speed first time it was found by dealer after third oil change approx. 15000 miles second 12000 miles later and now 306 miles latter with this time the leak was larger to to the fact that it triggerd the low oil light first two times it told to me it was oil pan gasket and a small leak which at the time made sense it not show up on the dipstick i know this was da problem on other Hyundai santa cruz models in previous years0
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.
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.
While driving the vehicle during winter the temperature of the engine dropped due to thermostat failure leading to no heat in the cabin and a check engine light. Vehicle was towed to the dealer as this failure can cause both engine damage and is unsafe for the occupants in freezing temperatures.
Coolant leaking onto engine shield and ground from front a small rock that hit of vehicle radiator. The radiator is not nearly shielded well enough to protect it from rocks and other debris. A 1/4 inch diameter rock struck the front of radiator through grill opening resulting in a leak and possible risk of overheating the engine. The radiator tube size is also made of extremely insufficient material to withstand any impacts. Hyundai dealer and corporate at this time refuse to take any responsibility for this issue and will not warranty the replacement. The car is a 3 month old 2023 Santa Cruz Limited with just over 3,000 miles on it. This is an extremely common issue with a quick google search of the 2022-2023 Santa Cruz.
Joined a Santa Cruz Owners blog immediately after purchase. This safety defect involves BOTH the 2022 and 2023 - ALL models. The front grill (especially the lower section) has no mesh and the openings are too big. Road debris entering this area can disable the Engine Cooling System and/or the vehicles Air Conditioning System. A protective mesh or screen has to be designed by Hyundai, to fit behind the grill, to deflect large rocks and objects that could disable the motor.
