Factory maintenance schedule OEM · verified

Normal service, condensed from the factory interval matrix.

Under the factory schedule, replace the engine oil and filter every 5,000 mi; spark plugs at 120,000 mi; coolant every 50,000 mi. The big-interval services (every 50,000 mi for coolant, and the transmission fluid) are the ones owners most often skip — on a lower-mileage example, assume the original fluids are still in it and check them first.

Reliability & federal safety record

Owner-reported issues, recalls, investigations and service bulletins on record with NHTSA — an unfiltered look at what owners actually experience.

The 2007 Lexus RX400H sits in a notable transition within its generation, reflecting a mid-cycle adjustment in quality and reliability trends. Complaints spiked sharply in 2006 (185) before dropping to 117 in 2007, suggesting Lexus addressed some early issues, though the volume remained elevated compared to 2005 (29). Recalls followed a similar arc, peaking at six in 2006 and halving to three in 2007, while investigations held steady at three for both years—indicating persistent, though not worsening, scrutiny. The 2007 model’s top complaint areas (brakes, structure, and vehicle speed control) mirror broader generational concerns, with 11 crash-related complaints underscoring durability or design questions. Fire complaints were minimal (1), but the data doesn’t specify root causes for any of these issues. The 2007 RX400H is a relatively safer bet within this generation, as it benefits from early fixes while avoiding the later-model unknowns, but buyers should still prioritize a pre-purchase inspection, particularly of the braking system.
