Question 1

Weak 12V auxiliary battery (1.8 Hybrid)

Accepted Answer

On electric and hybrid vehicles the 12V auxiliary battery powers the start-up electronics; when it weakens, the car may not go into Ready mode, show random warnings or refuse to charge. It is more common with infrequent use and after 4-6 years.

Question 2

Catalytic converter theft (Corolla E210)

Accepted Answer

Toyota hybrids are a prime target for catalytic converter thieves in the UK because their converters contain high levels of precious metals. After a theft the car starts with a very loud exhaust roar and an engine warning. It is not a mechanical fault but a very common reason for a large insurance claim.
