Should you buy a used 2015 Lexus RX?

The 2015 RX has 67 complaints[1] and one recall[2]. Other model years range from 11 to 284 complaints[3]. The recall remedy is available, so ask for proof that the fuel delivery pipes were checked or replaced. In the small sample of complaints we read, owners describe stalling and sudden power loss in some engine and fuel complaints[6][8], so notice how the car starts and accelerates on a test drive. The AWD versions have the higher NHTSA overall rating at 5 stars[5][19], the RX 450h versions have the better EPA combined MPG at 28 to 29[4][17], and we have no data on repair costs, so a pre-purchase inspection is a sensible step.

Complaints submitted to NHTSA by owners; unverified reports, one complaint can name several components. Complaint counts are not normalized by sales; compare years of the same model, not different models. EPA annual fuel cost uses EPA's current fuel price assumptions, not the price when the car was new. Horsepower is the rating listed for EPA test vehicles. Dimensions are Canadian-market specifications and can differ slightly from US models.
