Hello guys, got a hybrid 4th Gen RX, 2017, around 45k miles, the car went driving awesome untill few miles away, it's like when i switch from electric to the gas engine it's weirdly shaking, sounds like a missfire, but the interesting part is when I'm giving it a full throtle, maybe to around 4kRPM~, check engine light blinks and Master warning light appears, is it time for a new set of spark plugs? That early? I've just set an appointment to lexus service shop to figure out what happens... I wanted to ask here too maybe someone had an similar problem like mine...

 

First thing I would check is the 12V battery. If it hasn't been replaced, it can cause all sorts of random issues. It does sound too early for spark plugs so could be something else. Please share once you've found the culprit.
