Hi. Anyone experiencing hybrid system malfunction. This morning on my way to work this message popped up. In process getting it into dealership. 2024 LC
 
You are not alone... second time I have had this happen to me (September and last Saturday) at exactly the same location... going down Floyd's hill on westbound I70... very fun place for a car to go into limp mode.
  • Hybrid system malfunction
  • Drive-Start Control Malfunction
  • System Malfunction
  • Check engine

Just received word that Toyota told the dealership to replace the high pressure fuel pump.

Anyone have any experience or wisdom when it comes to this part? How big of an issue is this? Long-term issues caused by this part malfunctioning? Is this serious enough to start pushing for a new LC because of potential damage to the engine etc.

Any thoughts would be appreciated.

I had all those lights initially but now only the hybrid system malfunction light. I’m at dealership now

Generally this isn't too bad of a job. It can require lowering the gas tank to access the pump. Sometimes manufacturers are brilliant and have an access panel in the cargo area. However, I bet that isn't possible in the LC250 because of the hybrid battery. There are probably other things that make the job more difficult as well.

Especially right now with no shoulder on either side and the road surface awful from the construction. Glad you’re safe!
