What is your question?
The yellow-orange triangle came on with a message "REDUCE ENGINE POWER". I replaced the battery and the light and message disappeared. I only use premium gas and I have it serviced when it's scheduled. However four days later, it came back on. It runs just like it did the day I purchased it. However, that message and light is concerning me.
What makes this problem better or worse?
Not sure
How long has your 2017 Lexus NX200t had this problem?
A few days

Hi, this is Bo, an auto expert on RepairPal's Car Genius team! A reduced engine power warning that keeps coming back even after a battery reset is worth taking seriously even if the car feels fine to drive. On this turbocharged engine it could be pointing toward something like a boost pressure issue, a throttle body concern, or a sensor monitoring the intake or exhaust system. The fact that it temporarily cleared with the battery swap tells us it's storing a fault that keeps returning rather than a one time glitch. Since you're doing everything right with premium fuel and scheduled maintenance this one really deserves a proper scan by a Lexus specialist to pull the specific fault codes behind that warning.

Hi, this is Bo, an auto expert on RepairPal's Car Genius team! The symptoms you're describing, hard starting, RPM limited to 2500, and long crank times, are consistent with a fuel delivery problem so your instincts are pointing in the right direction. On the 3.8L Genesis the high pressure fuel pump is actually cam driven and does have engine oil present in that area since it uses oil for lubrication internally. So seeing oil around that pump is actually normal and not necessarily a sign of sabotage. That said the symptoms are real and concerning. A failing high pressure fuel pump, low fuel pressure, or a clogged fuel filter could all cause exactly what you're experiencing. Get a fuel pressure test done before assuming the worst and visit RepairPal.com to find a trusted shop that can properly diagnose this one!
