Watch for slow cranking, dim headlights, a battery/charging warning, and battery age over 4 years.

These symptoms are common on the 2018 Lexus RX 350L and tend to show up sooner in New England’s seasonal temperature swings. If you notice multiple signs, have the battery and charging system tested before you’re stranded. Our Hingham service team can test and replace the battery the same visit.

  • Interior lights flicker or dim at idle
