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)

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.

On 3 separate occasions this has occurred . When accelerating, the engine or power train completely loses all propulsion. Twice I was starting a left hand turn and crossing oncoming traffic. On one occasion I was turning right onto a 50 MPH highway and quickly veered off the road onto the berm. The only item on dash board flashing on the third incident was the cruise control preset and it was flashing 20. At the time I was not using the cruise control and I did not set it for 20. No dash board warning lights lit during the first two losses of power. I reported it to the dealer. Today I had a maintenance appointment and inspection at the dealer. After that inspection, they informed me that they found no codes to identify the issue. I should let them know if it continues. My 3 failures happened at approximately 10,000, 15,000 and 20,000 miles. My safety and that of my passenger were most definitely affected each and every time. After 30 seconds to one minute the full functionality returns as if it never happened.
