NHTSA Complaint #11441080 — 2015 KIA OPTIMA

Incident previously reported by telephone to NHTSA agent. On 11/19 while writing report online, [XXX] was accidentally disconnected from Internet at approximately 4:40PM CST. Lengthy comments with details. Can you retrieve? If not and again more briefly, an incident of dangerous unexpected engine shut down and engagement of limp mode occurred on 9/17/21 while [XXX], son, was traveling at 70-75mph in busy traffic on I-43 just north of Milwaukee. Engine eventually restarted but NO check engine light. Oil level okay. Fuel okay. Still precautionary check by [XXX] for possible engine error codes same day immediately after engine failure (limp mode) at Advance Auto in Manitowoc, WI and NO CODES FOUND. Subsequently NO CODES FOUND by dealer on 10/22/21 I have re-uploaded documents indicating Kia Tech Support states "Do not perform any repairs if the concern cannot be duplicated" and also "see if the customer can duplicate it for you." That is absurd and completely irresponsible nonsense! Customer or other driver should drive at high speeds hoping for engine shut-down? Personal injury? Property damage? Death? INFORMATION Redacted PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6). Consumer stated 2015 Kia Optima engine replacement per Kia lifetime warranty on 2/16/22. Vehicle has been diagnoised.
