For me, I hated to see parts missing or damaged on assembly. Wiring repairs or accessory installs made with scotch-lok connectors or wire nuts.Using crappy eBay parts. Using an entire tube of RTV sealant where only a dab was necessary. Messing with refrigerant including (illegal) venting to atmosphere. The list goes on and on but it boils down to improper techniques and materials. I really can't fault anyone for trying to do it themselves. Most of the people who read HN can afford an auto repair bill so I think its more the "hacker" mindset that influences people here to attempt repairs themselves. Just be honest with the service department if you got in over your head. We won't snicker too much :-)

This is good to know, I usually stay away from what I can tell is a "lifehack" style repair on YouTube, and I try to buy real parts. And good to know about the mechanic, I have a good relationship with mine and now I know how to keep it that way!

EDIT: P.S. yes, I do fall into the "I can afford the mechanic bill" category, but it isn't so much hacker mindset as sustainability and self reliance mindset.
