In this video I’m walking through 15 costly Tesla mistakes I see new owners make (and a few that I made early on too), so you can avoid burning money in 2026. I start with the big buying decisions—whether you should buy new, what to think about when it comes to FSD, and how people end up overspending on home charging setups when they don’t need to. I also talk about incentives changing over time and why you don’t want your entire ownership plan to rely on Supercharging for day-to-day driving. Then I get into the ownership habits that quietly cost you range, time, and wear: charging to 100% when you shouldn’t, skipping preconditioning, and not shopping your insurance. After that it’s the practical stuff that keeps your Tesla looking good and working right—avoiding contact car washes, defrosting the correct way, keeping the right washer fluid, checking tire pressure, rotating tires, setting trunk height, and knowing when OEM accessories are actually worth it. If you’re buying a Model 3 or Model Y, this is basically the checklist I’d want you to watch before delivery day.
