NHTSA Complaint #11675639 — 2016 KIA OPTIMA

Complaint Message – 2016 Kia Optima Engine Failure Without Oil Light Warning I am the owner of a 2016 Kia Optima (VIN: [XXX] ). My vehicle suffered complete engine failure due to oil starvation — without any prior oil warning light or indication. The engine died while driving, and it was only afterward that I discovered the engine oil was extremely low. The oil pressure light never illuminated at any point to warn me. I am aware that Kia previously recalled earlier model years (2011–2014) for similar engine issues under Recall SC147 and others, related to the Theta II engine and oil pressure-related failures. Many owners reported the exact same symptom — catastrophic engine failure without oil light warnings — that I am now experiencing in my 2016 Optima. Although my model year is not included in the existing recall, the failure pattern appears identical. I believe this presents a significant safety issue that should be investigated. A critical warning system (oil pressure light) failed to function properly, which directly led to engine damage. I am requesting that this issue be reviewed and investigated by NHTSA and Kia for potential expansion of the recall or warranty coverage to include the 2016 Optima. I have already contacted Kia and am pursuing further review through the dealership and customer support. Please note that other 2016 Optima owners have reported similar complaints online and in forums, and this issue may affect a broader number of vehicles than currently acknowledged.
