Why does the check engine light in my LC500h turn on when I start my car?

Are Lexus LC500h engine noises bad?

Unusual noises can signal a problem with your Lexus LC500h engine. Tapping or knocking could mean you need an oil change. A high-pitched whistle could signal an intake leak or misaligned belt.

What could damage my Lexus LC500h engine?

Can I use water in my Lexus LC500h radiator?

However, if you need to continue driving your LC500h when you’re out of coolant, having water in the coolant reservoir is better than nothing.
