I feel out of most car brands, Toyota’s electricals are arguably one of the most reliable. I don’t think a warranty for that is necessary unless you can afford it. My family has had a few Toyotas- a 2001 Corolla (ran to 300k miles), 2006 Tacoma, and a 2010 Camry. The Camry’s only issue I noticed was the cd player got wonky after a while. It has 227k miles on it and still runs perfectly otherwise. I don’t know of the other vehicles having any electrical issues.

Definitely the Camry
