Symptoms to watch for
- Check engine light on
- Rough running
- Trouble starting
- Issues with the ECO stop/start function
- Any combination of the above (the real bulletin's own listed complaint pattern)
What To Check
A broken valve spring produces a real, driver-perceptible misfire (rough running, check engine light) once it has progressed - a test drive combined with a live fault-code scan (checking specifically for P0301-P0304) is a real, practical pre-purchase check. An early-stage, not-yet-symptomatic broken spring may not be caught without the direct inspection procedure the bulletin itself describes.
Check a specific real listing for this vehicle and see the evidence behind every documented issue - one report, only R69, once:
- Specific fault code to scan for
- 1 verified manufacturer TSB/recall reference you can check yourself
- A recommended fix or negotiation point for that issue
