Very comfortable, luxurious, and powerful (very much so). The only drawback is the high fuel consumption. Extremely reliable, I don't see the inside of a repair shop.
Owners report a mixed experience with the Lexus RX: some are very satisfied with the comfort, quietness, and technology, especially older vehicle owners who appreciate the relaxed driving and reliability. On the other hand, a common complaint concerns recurring issues such as unnecessary alarms, inconvenient door design, thin leather seats that deteriorate quickly, and cheap interior trim that wears out within a few years.
