Symptoms NX 300h owners report

Reduced electric assist pulling away and merging, more obvious in a heavier vehicle than a sedan.
The engine running more of the time at low speed.
Fuel economy declining gradually.
Hybrid warnings, sometimes only in heat.
Fan noise from the rear seat area that gets mistaken for the climate system.

Repair or replace

A few weak modules with the rest grouped tightly: module-level repair.
A widening spread across the 34: replacement.
We measure every module and show you the numbers before recommending either.
The 12V battery is tested first, and the rear-seat cooling intake is checked for blockage.

Lexus NX hybrid battery questions

Is the NX 300h battery the same as a RAV4 Hybrid battery?

The NX 300h uses the same 34-module, 244.8V module as the 2016–2018 RAV4 Hybrid and the Camry Hybrid of that era. The assembly and part number are still confirmed against your VIN.

Why does the cooling intake matter so much on an NX?

The pack is cooled by cabin air drawn from a vent in the rear seat area. If cargo or a car seat blocks it, the pack runs hotter, and heat is what ages these batteries.
