Summary

The 2021 Lexus NX300h appears to be a generally reliable vehicle, but owners have reported some common issues. The most concerning, but less frequent, is related to hybrid battery degradation, which can be expensive to fix. Infotainment system glitches and interior rattles are more common annoyances. Overall, most issues are relatively minor and can be addressed without significant expense, but the potential for hybrid battery problems should be a consideration for prospective buyers, especially on higher-mileage examples.
