NHTSA Complaint #11700258 — 2017 HYUNDAI TUCSON

My 2017 Hyundai Tucson is experiencing severe oil consumption, which appears to be related to a known manufacturing defect affecting Hyundai engines from this period. My vehicle is burning through oil rapidly between normal oil change intervals, and it has begun showing signs of low oil levels despite no external leaks. This creates a serious safety concern because the engine can fail without warning. The dealership has acknowledged that excessive oil consumption is a known issue for this engine but refuses to provide assistance because I do not have “enough oil change documentation” over the years. However, this issue is not caused by lack of maintenance — it is a widespread internal defect that Hyundai has issued multiple technical service bulletins for. My car has been maintained, and oil changes were performed at regular intervals, even if I do not have complete paperwork. The rapid oil burning is ongoing and dangerous. I am concerned about the engine seizing, stalling, or failing while driving, which could lead to a crash. This is a safety hazard that should be investigated and included with other Hyundai engine cases. Requested Action: I am asking NHTSA to investigate this oil consumption defect affecting the 2017 Hyundai Tucson and require Hyundai to provide a remedy, including repair or engine replacement, regardless of perfect maintenance documentation, since this problem stems from a manufacturing flaw.
