NHTSA Complaint #11422987 — 2014 HYUNDAI VELOSTER

Since Nov/Dec 2020 low oil warning lite started flashing at 2 separate svc intervals for oil change maintenance. At service visit in Jan 2021 requested dealer to inspect for oil leaks. None were found but since then I began checking oil level regulary & found out the car was consuming excessive amount of oil…about half a qt every 250-300 miles. At next service appt to have oil change I informed dealer of my findings which he advised performing the 1000 mile consumption test & wait till after to change oil. He advised if vehicle fails consumption test Hyundai’s guidelines suggest a Combustion Chamber Cleaning (at a cost of over $400)! My complaint is if the cleaning is part of Hyundai’s Repair Guidelines & there’s no other alternative to this step, (as referenced in TSB# 21-EM-003H) why does the customer have to pay the $400+ to have it done if the customer’s vehicle has less than 100000 miles so it should still be covered under the 10 year/100000 mile powertrain warranty.
