   On March 04, 2026, I took my 2019 Hyundai Santa Fe to the local dealer for oil change service.

    Engine continuously burns oil excessively and the dealership is falsifying the oil consumption test. At my local oil change shop, there is no oil left on dipstick at 3,000 mile interval. When I took it to dealer for consumption test, they checked dipstick after 1,000 miles and it was OVER THE FULL LEVEL. How can the oil be over the full level? This indicates they overfilled it to begin with and invalidated the test. Hyundai corporate is doing everything they can do avoid…
