NHTSA Complaint #11599872 — 2017 HYUNDAI TUCSON

Hello, I have a serious problem with my Hyundai Tucson 2017 which is excessively burning oil. An oil change has been done on December 26 2023 (125.600) and a service was due 3 month later (3.000 miles) to perform an oil change but when I went for the oil change on March 26, 2024 at Jiffy Lube, they noticed that there was no oil in the engine and no leaks and suspected that the vehicle might burn oil and the performed a full synthetic oil change (service due after 7500 miles) and after 2800 miles on May 17, 2024 when I checked the oil level, I couldn't see any mark on the stick. I brought them the car and they checked if there was any leak then they filled up the engine. I was monitoring and on June 15, 2024 after 780 miles the level was below the minimum level. I bought a Mobil 1 full synthetic motor oil 5W-30 and filled up the engine up to the maximum level mark on the stick. 2 weeks later, on June 28 I noticed that the oil level was close to the minimum level again. I booked an appointment at Hyundai dealership at Gaithersburg, MD and they refused to check the vehicle without a payment. I paid for the diagnosis and 2 day after they ended up saying that the vehicle is burning 1 quart every 2660 miles (which is below what we observed) and they asked me to pay $1235 for a combustion chamber cleaning to which they added it might not work. I am submitting this request for you to solve this safety problem on my car. Thank you
