Overall
Mixed to positive sentiment overall, with a clear distinction between praise for its luxury, comfort, and refinement, and criticism for its driving dynamics, software reliability, and platform origins. The vehicle is consistently described as a comfortable, quiet, and well-built luxury sedan with a premium interior feel, superior sound deadening, and a smooth ride. It is favorably compared to its sibling, the i4, for being more refined, spacious, and feeling like a more purposefully engineered electric vehicle.
Best version to buy
Insufficient owner data available to declare a consensus "best" trim. The M60 performance variant is mentioned but receives criticism for its handling.
Known issues
Overall
Sentiment is mixed and varies significantly by vehicle generation. Long-term owners of older models (specifically pre-2021, with mentions of a 2015 model) report severe dissatisfaction with long-term reliability and ownership costs, describing the vehicle as poorly designed for longevity with frequent, expensive failures. In contrast, discussions of newer models (post-2021) are more focused on competitive positioning, with feedback indicating they are perceived as technologically capable but lagging in interior luxury, build quality, and overall refinement compared to newer premium electric vehicles.
Best version to buy
Insufficient owner data available to designate a specific model year or trim (e.g., Long Range vs. Plaid) as the "best" among community discussions.
