Less than 40 shops in the US that work on hybrids? Lol According to Google there's 230,000 auto repair shops in the US. That map is beyond worthless.
When I bought my Prius in 2006, no mechanic was willing to touch it. Now 99% of the shops will do repairs especially, non hybrid like wheel bearings, water pumps etc. Today, this is the same case with Tesla. No mechanic will go near them. I am not talking about HV batteries, they will not even replace control arms or plug and play MCUs and screens. Anyway, I never found a trustworthy hybrid shop in Northern Virginia. If you know one let me know. I do almost everything DIY. I do not trust even the Toyota dealer who burned me before.
