New Owner Questions

The basics almost every new owner asks in the first week.

Q. Do I need to charge to 100% every night?

No โ€” for daily driving, a moderate charge limit is easier on long-term battery health than routinely charging to full. Save 90โ€“100% for the day before a longer trip.

Q. How do I open the doors if the 12V battery dies?

There are mechanical backup releases for the doors, frunk, and trunk โ€” it's worth locating and testing them once, calmly, rather than discovering them for the first time during an actual issue.

Q. Can someone else drive my car safely without my login?

Yes โ€” add them as a Phone Key or use a card key rather than sharing your account credentials. Permissions are adjustable and easy to revoke later.

Q. Is it normal for the car to make odd sounds while parked?

Some background activity (battery conditioning, cabin overheat protection, etc.) can produce faint sounds while parked โ€” if something sounds mechanically wrong rather than electronic, it's worth a service inquiry.

Q. Do I need a home charger installed right away?

Not necessarily โ€” a standard outlet or the included mobile connector can work temporarily for light driving while you compare Wall Connector installation quotes.

Myths, Debunked

Some of these were true once, some never were.

MYTH "Charging to 100% every night ruins the battery immediately"

It's not an immediate problem, but it's not ideal for daily use either โ€” the accurate advice is to keep it moderate day-to-day and save full charges for when you actually need the range.

MYTH "EVs are more likely to catch fire than gas cars"

Broad safety statistics and reporting on this vary and are frequently debated โ€” rather than repeating a stat here, it's worth looking at current, cited safety data if this matters to you.

MYTH "Cold weather 'kills' EV batteries"

Cold temporarily reduces range and charging speed โ€” this is normal battery chemistry, not permanent degradation, and performance returns once temperatures rise.

MYTH "You can't get a federal EV tax credit anymore, period"

The federal new/used EV purchase credit ended for vehicles acquired after September 30, 2025, with some exceptions for binding contracts made earlier โ€” but state and utility incentives are a separate, often still-active category worth checking.

MYTH "Sentry Mode will drain your battery overnight"

It does use some energy while active, but for most owners it's a modest daily draw rather than a dealbreaker โ€” worth disabling only in very low-traffic private parking if you're especially range-conscious.

Money Questions

The cost questions that come up most often.

Q. Is home charging really cheaper than gas?

For most owners, yes โ€” especially charging off-peak on a time-of-use electricity plan. Exact savings depend heavily on local electricity rates, so it's worth doing the math for your own utility.

Q. Are Superchargers more expensive than home charging?

Generally yes, per mile โ€” Supercharging is convenient for trips, but routine daily charging at home is almost always the cheaper habit.

Q. Is insurance more expensive for an EV?

It varies by carrier and region โ€” shopping quotes annually and asking specifically about EV/Tesla repair experience tends to matter more than the EV status alone.

Q. Do I need to budget for regular maintenance costs?

Ongoing costs are generally lower than a gas car's โ€” no oil changes or engine maintenance โ€” but tires wear a bit faster due to instant torque and added weight, so budget for that instead.
