Outcome

Out of warranty and quoted $10K by Subaru to replace a faulty sound system, a poster says he fed ChatGPT Australian consumer law guidance and the warranty terms, asked it to find related complaints and tribunal cases, and had it draft a firm email. He says 48 hours after sending it, Subaru called and offered to replace it at no charge.

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: Write a firm, factual complaint asking a manufacturer to fix a faulty product under consumer law.

Fill in before running:
- My country/state: [LOCATION]
- Official consumer-rights guidance (links or text): [PASTE]
- Warranty terms: [PASTE]
- Fault history with dates and the quote: [DETAILS]

Rules:
- Use only official guidance and the documents I give you; quote them accurately.
- Look for public reports of the same fault and link them.
- Write a calm, specific email with a clear request and a reply deadline.
- Name the official complaint route if they refuse.
- 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.
- Check the email for exaggerations before sending; stick to facts you can prove.

Output: A one-page complaint email and a list of evidence to attach.

You'll know it worked when: the email is sent to the right contact with evidence and a deadline.

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

  • Thomas Weilbach's car was out of warranty, and the dealership said the only long-term fix, a full engine replacement quoted at €6,000, would be paid out of pocket. Weilbach used ChatGPT in research mode to dig into the symptoms (oil consumption, juddering under load and limp mode), known problems with that engine, service bulletins and how others had handled similar cases, testing each possible cause against the symptoms. ChatGPT then helped turn it all into a clear, structured argument. Weilbach took the case to the dealership, and the manufacturer approved the full engine replacement under goodwill at no charge.

  • A driver whose new 2025 Elantra's head unit failed (no CarPlay, broken navigation and Bluetooth) ran his whole lemon-law fight through Grok. After three dealer visits, the last a refusal to touch the car, Gemini advised waiting before sending the lemon-law letter; Grok said to lock the mileage, film the refusal, mail the letter and file with the state AG the same day, and he followed Grok. When the AG and Hyundai turned him down, Grok pushed him to file with BBB AUTO LINE and wrote a line-by-line rebuttal. He says the arbitrator ordered a repurchase in August and his loan was paid off to $0.00 in September.

  • Four weeks after buying a used car that kept developing problems, even after a warranty repair, a UK buyer thought he was stuck: the dealer's 30-day return only covered up to 250 miles and he'd done about 500. ChatGPT told him about his rights under the Consumer Rights Act 2015, and he says one email later the dealer agreed to take the car back with a full refund.
