Our car had 2149 miles on it. Engine started to stalled on [XXX] on [XXX] from OKC to Tulsa. We made it to Tulsa. The car was towed to Tulsa Hyundai dealership on 12/25/2024. After diagnostic on 12/26/24, we were told the car had bad gas. The dealership performed the necessary work including replacing 4 fuel injectors in order to fix the problem. It cost $3991.52 and it took a week. We were told since this was not a manufacturer problem that we are responsible for the repair. We paid for the repair. We always get our gas from Costco. So we filed a report with Costco stating that we got bad gas from them. Costco turned it into their adjuster at Gallagher Bassett. He investigated and told us that his findings indicated that Costco did not have bad gas in the month of December according to their quality reports. No other cars filed complaints regarding gas issue. Our claim was denied. The question remained where the bad gas came from. Was it truly a bad gas problem or did the car have fuel injector issues and that bad gas was a cover up. We bought a new car, we purchase gas from a reputable company and we ended up with this problem that we were responsible for through no fault of our own. We are filing a report to see whether there are other cars of this model that had similar issues. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
