What Li Auto L9 (EREV) owners report first
If your Li Auto L9 (EREV) is from an early build, this is one of the first things to check. Issue 1 — Engine-mode noise transitions are noticeable. On the Li Auto L9 (EREV), owners typically notice this within the first 12–24 months. The diagnosis path is well-mapped: a connected scan tool reveals it quickly, and the fix is usually a documented service-bulletin procedure rather than experimental work. Issue 2 — Software bugs on early MY2022 (resolved). On the Li Auto L9 (EREV), owners typically notice this within the first 12–24 months. The diagnosis path is well-mapped: a connected scan tool reveals it quickly, and the fix is usually a documented service-bulletin procedure rather than experimental work. For a 44.5 kWh, 1100 km full-size electric range-extender suv like the Li Auto L9 (EREV), these patterns are well within what the platform is designed to handle once the right service-bulletin steps are followed.

- Are there any open recalls on the Li Auto L9 (EREV)?
- Recall status changes — check the brand's service portal with the VIN before purchase. Any open recall is fixed for free, so it is actually a slight positive on a used buy: free brand-paid service on the way in.
- Should I avoid early production years of the Li Auto L9 (EREV)?
