Auto Express's reliability ratings are based on our Driver Power survey of over 30,000 car owners. Ratings are the average for all owners of this car who responded. Individual owners’ ratings and comments appear below.

Although six years old, 2015 is the first showing for the Lexus RX in Driver Power, and at 16th place it’s done Lexus proud. Reliability and build quality sit just outside the top ten of all 200 cars surveyed, and seat comfort is placed fifth.

Combined with excellently rated ride quality, the RX is a lovely car to melt the miles away in. Not necessarily to do corners in, however, with road handling ranked poorly. It’s pricey to run, too, say owners, though that’s offset by strong acceleration.

Y-reg Petrol, Owner for 3 to 5 years

I have had a lot of cars since 1960. From minis to bentleys. I raced special saloons in 71 - 73, I know what I like. My time with the Lexus is definatly the longest I have owned a car. its reasonably quick considering what it is. It has aquaplaned because of flooded roads-the braking/ ABS and stability was brilliant. Its comfortable and never a problem to start and you dont have to think about reliability etc. The economy could be better but after all it is a 4X4. This Lexus with a volvo D5 lump and miles to go meter would be brilliant!

Its been an excellent car,I get over 31MPG..will go upto 40MPH on the electric motors alone.4 x 4 drive worked fine in the recent bad icy conditions.On the service some small bubbling was noticed on two of the alloy wheels and Lexus replaced all 4 wheels under the warranty,thats honesty for you from a top brand company, as I had not seen the problem but they noticed but did not ignore it.
I plan to up-grade to the RX 450H next year.

Car hasn't been used for 3 years. it developed an issue where 2 lights were displayed on dash. abs and a general warning light. Doesn't cost anything it hasn't moved in 3 years. other than the finance.
