2010–2015 Lexus RX350 repair guides
The third-generation RX350 (2010–2015) is famously durable, and most of what fails at high mileage is the cheap stuff: coils, belts, struts, bulbs and brakes.
These guides were filmed on a 2010 RX350 owned and maintained for over a decade. The third generation shares its 3.5L 2GR-FE V6, suspension, brakes, lighting and most interior trim across every year, so the same procedures apply to the 2010, 2011, 2012, 2013, 2014 and 2015 Lexus RX350. Check the parts notes for fitment before you order; a few trim pieces changed with the 2013 facelift.
Also fits the RX450h hybrid of the same years for most non-drivetrain jobs (brakes, struts, wipers, lighting, filters).
