• Fuel-efficient hybrid powertrain, smooth ride, luxurious and comfortable interior, smart electronics interface.

• No third-row seat, expensive option packages, questionable economic and environmental benefit.

  Very impressive vehicle - 2010 Lexus RX 450h
  By dorene - December 25 - 11:06 pm

  We are so impressed with our 450h. The handling is excellent; it glides and flies down the road. The steering is tight and the car responds with little effort. We took a trip with our two adult children and a 14 year old; the middle seat is a bit tight, but it handles full capacity comfortably for the most part. Tech features are fun and mainly intuitive. The mouse is fun and useful. Voice navigation has limits but reads well. We love the heated/cooled front seats and classy interior; love the interior lights. Dont like the park assist; it over reacts and is annoying; other downside is it tends to be a little underpowered at times, but nothing major. Overall a total winner!

  Scoop on Mileage - 2010 Lexus RX 450h
  By His and Hers - October 16 - 10:56 am

  My wife and I both drive this car, and I wanted to let people know our experience about gas mileage. My wife drives the car just like she always has driven any vehicle. She routinely averages about 25 to 26 MPG. I have found that, if I deliberately drive to maximize mileage (no jackrabbit starts, stay at 70 on the interstate, take it easy in general, but nothing extreme) I can consistently average 29 or 30 MPG. I would stress that these are AVERAGE mileage. Often people (and car ads) talk about the highway mileage as though that is the mileage. The really strong suit of these hybrids is their combined mileage. An SUV that can average 30 MPG if driven calmly is pretty impressive to me!

  A great second generation hybrid - 2010 Lexus RX 450h
  By reeveswilson - June 5 - 8:30 pm

  I bought the Rx450h after leasing the Rx400h, buying it off lease and giving it to our son. While the Rx400h was great, the Rx450h is a great improvement with even better mileage. The size is perfect - larger than the 400h but still small enough to be nimble in town and larger enough to feel roomy on the road. We get 28mpg+ (about 1mpg better than the Rx400h). I love the improved comfort, the ventilated/heated seats, the technology plug ins; did I say it was great throughout the last 3 snowstorms that hit Washington, DC? The technology and interior design are improvements over the the rx400h. I loved the RX400h I bought he RX450h when the 400h lease was over.

  Loving the Lexus - 2010 Lexus RX 450h
  By S Hodgson - March 26 - 3:45 pm

  Ive been driving my RX 450H for around 4 years and love it. I spend a tremendous amount of time driving for work and wanted something nice/comfortable. We purchased the extra maintenance plan and at 125,000 miles, so far Ive done nothing but the scheduled oil/maintenance, covered under my plan. More importantly, I love driving it. I concur that milage is contingent upon driving style. I average 28 mpg even hitting 80mph with highway driving, by avoiding quick acceleration and taking my foot off the accelerator when I know Im braking soon. My only frustration is the USB port location is inconvenient which theyve changed in newer models. I leave the connector plugged in so rarely have to access it the port. My Lexus dealership couldnt be more accommodating during maintenance, with a loaner if reserved beforehand, shuttles to the mall across the street if desired, and a nice set up at the dealership where I can work or watch TV in designated lounges. (Johnson Lexus, Raleigh NC) I highly recommend this car and wouldnt hesitate to buy another lexus after this experience.

  Surprised at low resale - 2010 Lexus RX 450h
  By Steph G - February 8 - 12:17 pm

  We have taken very good care of our 2010 Lexus RX450H the past 3 years (second owner). Low miles, no accidents, garaged....ect. We have been looking at the value of our 450H on Edmunds and Kellys.....shock that we are already under loan value. And we put down several thousand at purchase to cover the gap. Very disappointed. And this Hybrid never met its promised mpgs either.

  Lexus Lemon Car - 2010 Lexus RX 450h
  By kimfrazier - January 31 - 10:02 am

  I bought the 2010 RX 450h after having a 2002 GS 300 that served me greatly for 7 years. However, the RX stranded me in the middle of a busy intersection after 1 month and 2000 miles. This car has given me nothing but problems since I bought it and it has been in the shop 20 days of the 50 days that I have owned it. Lexus does not build the quality cars it used to. I would not recommend buying this car. You will regret it!

  Love this car! - 2010 Lexus RX 450h
  By miss_mija - January 7 - 2:23 pm

  Overall great car. We were looking for a luxury family car with a quiet cabin and this vehicle suits our needs. The ride in this car if very comfortable and the cabin is quiet. Its a smaller SUV which suits me and my family fine. I only have one small child and found it easier and more practical to install the car seat behind the passenger side. Putting a car seat in the middle limits the space for another passenger. Also love that the vehicle if relatively low maintenance.

  Just an owner for over a month, but what a car! - 2010 Lexus RX 450h
  By Dorkyman - September 24 - 1:39 am

  Bought a 2010 RX450h from the Portland, Oregon Lexus dealer a month ago. Weve taken it on several 4-hour trips and Ive driven it every day on suburban roads with some freeway. Overall about 26mpg regular or premium, so well stick to regular gas in the future. Ive noticed that I can nurse the mpg up to perhaps 28mpg by babying my acceleration and braking, but I prefer to drive in my normal fashion; anyway, gas is cheap and saving gas money wasnt the motivator. Pros: beautiful and luxurious. Surprisingly economical. Like a gorgeous woman who still loves tacos and beer. Minuses: Has middle-grade stereo, boomy bass at about 100Hz, (Im an audio engineer, this really bugs me but what the heck), unknown future battery replacement cost (but other Prius hybrids have lasted for 200k+ miles, plus its a Toyota/Lexus). UPDATE December 2016: Now that its cold outside, it takes ~10 minutes before the engines toasty warm, and meanwhile the fuel economy is lousy. So if my trips are just 10 minutes every time, I get more like 22mpg. I would assume the EPA tests are done with a fully-warmed-up engine, which is why there is such a large discrepancy.

  Rx 450 - 2010 Lexus RX 450h
  By Al - September 13 - 5:36 am

  We bought the 450h awd w, nav, 19 rims and a few packages. Great decision. We drove it 2000 miles to Canada last week and got 31.5 mpg cruising with a full car of kids and gear. We have no complaints. Smooth and not able to tell when the motor transitions. Tested all gas and hybrid suvs and only one other came close: the highlander. This has more power, better mileage, and cvt. We like the style, comfort and handling. 3000 miles so far and no trouble.

  Love it! - 2010 Lexus RX 450h
  By NoDuplicates - June 20 - 12:30 pm

  I went from a Lexus IS350 to the RX450H AWD. I was hung up on performance, but there is no comparison. Utility with MPG was my need for the long term. I got a lot more. The car drives like a dream. There is plenty of power for normal city and highway driving. However, dont expect to floor it at a light and whip ahead of the car on your left. Its not built for this but it can do it if you want to shoot the MPG to hell. On the highway, throw the trans left into manual and downshift to 4th gear for extra passing power. Comfort is king, fit and finish are perfect. Good ergonomics, handles well with 19" rims on curves. Instrumentation beautiful and relevant.
