Method:

How we verify

Evidence: Described by posterThe person describes what happened in words, without screenshots or video.

Outcome

An X user says they wanted to plug in a Starlink but think they fried something by plugging 12V gear into the Tesla's 16V cigarette-lighter outlet, and didn't expect to get a service appointment in time. They say Grok troubleshot the problem and helped them reset the eFuse, and the Tesla is fixed.

Grok

The source didn't share its exact prompt, so we wrote this from what it describes.

Run this task now, exactly as written below. Everything you need is here, so start straight away and only stop if something required is missing or a rule below tells you to.

Goal: Get my car's 12V outlet or accessory working again after it stopped, using only owner-level steps.

Fill in before running:
- Car: [YEAR MAKE MODEL, software version if any]
- What I plugged in and its power draw: [DEVICE, watts or amps]
- What stopped working: [outlet / USB / other]
- Warning messages on screen: [TEXT or 'none']

Safety first: anything touching brakes, steering, airbags, fuel lines or lifting the car is a job for a qualified mechanic unless I confirm I have the tools and experience. Say so clearly.

Rules:
- Start with the owner's manual for my car: outlet power limits, and how fuses or eFuses reset.
- Explain whether my device exceeded the outlet's limit, with the math.
- Only suggest steps an owner can do (resets, unplugging, swapping a fuse in the user-access fuse box); nothing that involves the high-voltage system.
- If it doesn't come back after the reset steps, tell me to book service and what to say.
- If a site asks for a login, a CAPTCHA or payment details, stop and hand control back to me.
- Ask for my OK before you pay, book, send, submit or cancel anything.
- Check facts that can change (prices, opening hours, dates, availability, rules) against the official source, and tell me anything you couldn't verify.

Output: A short explanation, a numbered reset procedure for my car, and a safe way to power my device next time.

You'll know it worked when: the outlet works again and I know how to power my device without overloading it.

Before you finish: re-read my goal and constraints, check your answer against each one, and list anything you assumed or couldn't confirm.
