Lexus GX 550 Luxury AWD earns praise for redesign
The 2024 Lexus GX 550 Luxury with AWD debuts a powerful 3.4 liter twin turbo V six and 10 speed auto. It adds a glass roof, refrigerated center console, captain chairs, adaptive suspension and six terrain modes. Fuel economy trails rivals, but off road capability and safety tech impress. Automotive columnist Barry Spyker notes the hybrid variant arriving in 2025.
Why alternators fail besides bearings and brushes
Ray Magliozzi explains that while bearings and brushes wear, the main electrical failure in alternators comes from diode bridges burning out. Jostling, heat, and aging wires can cause shorts, while voltage regulator spikes injure diodes, making aftermarket repairs short-lived and leading shops to replace with new or factory rebuilt units for reliability.
