Need advice on dealing with a failed Nissan repair that's still under warranty.
Timeline:
January: X-Trail started showing idle-stop system errors and engine misfires (RPM surging during acceleration). Nissan Narita diagnosed it as P0300/P0301/P0302 codes (cylinder misfires) and quoted ¥67k for spark plugs + ignition coil replacement.
March 15: Paid ¥69k, they claimed repair was complete. Did NOT provide any post-repair diagnostic report.
March 17 (2 days later, 350km driven): Exact same problem returned. Idle-stop error appeared again, check engine light ON, same RPM issues. I drove 350KM from Narita airport to my city.
Current situation:
Going to Nissan (Aizuwakamatsu – the city I live in) again tonight for diagnosis. I have:
- Original January quotation showing the misfire codes
- March invoice showing ¥69k payment
- Warranty certificate (6 months/10,000km coverage)
- Photos of the error messages
Questions:
- What are my rights here? The repair clearly failed within warranty period.
- Should Nissan Narita be responsible for fixing this at no charge, or do I need to pay Nissan (Aizu) and claim reimbursement?
- If Nissan (Aizu) finds the parts were never actually replaced (fraud), what's the process for reporting this?
- Any tips for dealing with this at the dealership? I have everything documented but want to make sure I handle this correctly.
Has anyone dealt with a similar situation? The fact that they didn't provide a post-repair diagnostic report seems like a red flag to me.
Vehicle: 2014 Nissan X-Trail, 85,700km
