Signs
- Inverter / oil pump errors (inverter codes
DI_/DIR_), power drop or rear drive shutdown. - Most often on 2017–2019 builds; the 980 motor itself was fitted until roughly 2022–2023. Non-Performance AWD cars from about mid-2019 and the Model Y Long Range have a different rear motor, the 990, which is less prone to inverter trouble.
Solution
- Replace/repair the inverter, check cooling.
- After replacement, reflash/initialize the new unit per the Toolbox procedure (see manual). The reflash alone won't revive a dead inverter: it is a mandatory step after the hardware swap.
Cost (Minsk shop prices)
≈ $1 000–2 000 for inverter repair / related work (without replacing the entire DU).

By field reports the '990' shows good reliability and longevity. The best pick for a pre-facelift.
Tesla Model 3/Y LFP 60–64 kWh (CATL/BYD): durably reliable, but RWD only
LFP batteries (CATL/BYD) are a good choice for long-term ownership: low degradation with daily 80–100% charging and simple operation. Usually fitted to RWD.
Model 3/Y 79 kWh LG (Europe, NOT China): a reliable choice
LG 79 kWh (EU) shows the lowest failure rate per field reports. A good balance of longevity and charge.
Model 3/Y 54 and 75 kWh (pre-facelift, before 2021): imbalance happens, but less often
The 54/75 kWh packs (pre-facelift) are generally more stable than 82 kWh, but imbalance is possible. What to look at when buying and servicing.
