general problems of the 2014 Hyundai Tucson

An authorized Hyundai dealership performed a major engine replacement on my vehicle on June 11, 2024. The vehicle mileage was documented as 110,797 miles in and 111,799 miles out. In September 2026, after the vehicle had reached 129,430 miles, I brought it to an authorized Hyundai dealership because of a severe gasoline odor and evidence of gasoline entering the engine oil. The dealership documented the vehicle at 129,430 miles in and 129,431 miles out. The documented mileage from the 2024 engine replacement's out-mileage of 111,799 to the September 2026 diagnostic in-mileage of 129,430 is 18,633 miles. The vehicle was returned to me, but the fuel/oil contamination condition recurred within approximately 48 hours. The oil level subsequently increased substantially. I repeatedly requested the dealership's technician narrative, diagnostic findings, test results, and electronic service documentation showing what was inspected, what was tested, and what findings supported the dealership's diagnosis. The dealership performed the work, yet these records have not been provided to me. Hyundai corporate has also not provided the requested documentation and has directed me toward additional diagnostic expense rather than providing the records from the inspection already performed. The 2024 engine-replacement documentation lists the replacement engine and associated service parts, including service kits 21111-2gk50-qqh and 21111-2gk70-qqh, as well as oil-cooler pipe/hose assembly 25470-2g050-qqh. I am requesting that the actual service records establish what components were installed, replaced, transferred, or reused during that repair. I am not claiming that the available information by itself establishes the root cause. My concern is the recurrence of apparent fuel contamination of the engine oil only 18,633 miles after the documented engine-replacement out-mileage, combined with the lack of diagnostic documentation from the authorized dealership's inspection. I am su.

The high pressure fuel line began leaking gasoline after warrantee replacement of engine.

Engine sputtering before turning on and strong gas smell throughout vehicle and near engine.

I brought my car to dealership three times in two month period time. The first time was because car wasn’t starting and I need to replace spark plugs , second time was because camshaft position sensor and now the engine has failed.

The contact owns a 2014 Hyundai Tucson. The contact stated that the oil warning light was illuminated. The contact then stated every two weeks had to add two to three quarts of oil and he noticed that a dark gray cloud of smoke came from the tail pipe. The vehicle was taken to the dealer where the oil line was replaced and an oil consumption test was advised however, the test was not performed. The vehicle was not diagnosed or repaired. The manufacture was notified of the failure and the contact was provided a case number and advised to call the NHTSA hotline. The failure mileage as approximately 116,000.

The first time while driving my engine seized on my 2014 Hyundai Tucson I had a loaner from the dealership for almost a year. They were waiting for a new engine to come from korea to California to pennsylvania. The second time while driving the car got extremely hot and oil was squinting everywhere the third time a recall on the engine they took my car Feb 25, 2022 it sat at the dealership for almost 6 months telling me my VIN was taking off the recall list I packed my SUV up 2 days. It went on silent came out so horribly loud, it was hot from behind and the side. The cr is not save to drive the man working there said so. I have been dealing with Hyundai America internal affairs since Feb. Now I have a lawyer. This is so messed up.

Bought car in Dec 2017. July 8, 2018, car caught on fire while driving. No issues before this event. No warning, care just went up in flames starting from under the car/the engine. There have been recalls on other models of Hyundai cars, but they do not include Hyundai tuscons. I think this needs to be investigated before someone loses their life due to this car.
