Best reliability of the three

by on
Vehicle: 2006 Lexus RX 400h 4dr SUV (3.3L 6cyl gas/electric hybrid CVT)

I've purchased a Ford Taurus and a GM Alero brand new and both vehicles had $2-$3k issues just after 3 years of ownership. I bought a 2006 RX400H used in 2009 (from dealership, it was leased). Initial problem was the battery in the CPU; I don't believe the dealership changed it out and I couldn't start the vehicle if it sat for longer than 24 hours. Since then, no problem - just regular maintenance. Put one new set of tires on it, avg MPG is 27 (being very conscious to "coast." Best savings: my husband sat in 3 hours of traffic to drive 45 miles due to a snowstorm and used less than 2 gallons of gas.

Great deal of comfort smooth quite ride with fuel approx. 28 mpg. Lower mpg on highway. Largest complaint Tires wear out at a much greater rate than any car I have previously owned. Checked alignment etc. to no avail a constant issue. Also have had two batteries!




Third rx

Flawless in quality (no repair needed ever on any of three RXs I've owned over past 9 years).




Love it

I have had the RX 400h for 2 years now and my wife and I love it. The power and quick acceleration when needed was a surprise. The turning radius is extremely small and steering is the best I've ever had on any vehicle. I think the ride is exceptional and quiet. My first experience with a hybrid and it has exceeded my expectation.

A new driving experience

by on
Vehicle: 2006 Lexus RX 400h 4dr SUV (3.3L 6cyl gas/electric hybrid CVT)

After 10 months of driving the RX 400h I am sold on this car. I previously owned a non-hybrid Lexus RX 300 and the hybrid is so much more powerful and fun to drive. I am averaging 26 mpg which is more than adequate for the size and weight of this car. The challenge is to see how far you can coast on battery power in order to increase your mileage. This takes a light foot on acceleration as well as easy breaking. As with my 6 previous Lexus automobiles, this car has required no servicing to date and should prove to be very reliable. The acceleration is more like a V8 due to the combination of electric motors and gas engine. We've been to the mountains and had no problems on the hills.




Excellent car! perfect choice for

Vehicle: 2006 Lexus RX 400h 4dr SUV (3.3L 6cyl gas/electric hybrid CVT)

I recently purchased a certified used '06 hybrid (the first my local dealership had), and I have to say I absolutely love this car! I had been keeping an eye out for a used one. I am really happy with everything so far, especially the mileage. Since mine has been already "broken in", I am averaging 28-29 mpg, granted I do a lot of street driving, so that helps. Everything I loved about my previous RX is here and many things have been improved, so I don't have any real complaints. The only thing that could be improved further is the nav system, in my opinion. I'd highly recommend this car.

What's New for 2006

Lexus introduces the first luxury-brand hybrid vehicle, the 2006 Lexus RX 400h SUV.

Introduction

Lexus is leading the way in the luxury hybrid market with the introduction of the 2006 Lexus RX 400h. Based on the ultrapopular Lexus RX 330 SUV, the RX 400h offers traditional Lexus luxury combined with improved fuel economy and eco-friendly utility. Available in either front- or all-wheel drive, the SULEV-rated Lexus RX 400h uses a new hybrid system that combines the efforts of a 3.3-liter V6 engine with three electric motor-generators, scoring an EPA rating of 33 city/28 highway. Equipped with a continuously variable transmission, the Lexus hybrid SUV boasts an impressive 268 hp. That's 38 more horsepower than the RX 330. With a 0-60-mph time of just 7.2 seconds, the RX 400h's quick acceleration belies its frugal fuel consumption. Typically, the RX 400h gets underway with electric power until the computer deems it necessary for the engine to fire up. This makes for quiet takeoffs, but it also highlights other noises that can be intrusive.

To ensure a serene driving experience, Lexus added an acoustic glass windshield and a quieter radiator cooling fan. The battery pack, which is the heart of the hybrid system, is housed under the Lexus 400h's rear seat. With 30 modules comprised of eight cells per module its total peak power is 80-percent stronger than the Toyota Prius'. Another new piece of technology introduced in the RX 400h is an all-encompassing vehicle stability control system Lexus calls Vehicle Dynamic Integrated Management (VDIM). Instead of reacting to an already occurring driving situation, VDIM is designed to anticipate vehicle instability in every direction while making corrections.

On the road, the Lexus RX 400h waltzes up steep highway grades as if it was taking a stroll through the suburbs. It feels considerably faster than the RX 330, a vehicle it outweighs by 300 pounds. Additionally, the 400h hybrid has tighter suspension tuning than its Toyota Highlander Hybrid cousin, and this, along with its 18-inch tires, makes for a more engaging drive without compromising the plush ride Lexus buyers expect. The 2006 Lexus RX 400h may command an $11,000 premium over a base RX but it comes loaded with nearly every possible feature.

The standard equipment list includes items such as power-adjustable front seats, stability and traction control, second-row seats that slide and recline, dual-zone automatic climate control and a power rear hatch. Options on the RX 330 that have been made standard on the RX 400h include leather interior trim, a roof rack with rails, a one-touch open/close moonroof, a DVD navigation system with rear backup camera, a six-disc CD changer, xenon headlamps that swivel when you turn and 18-inch alloy wheels. Put all of this stuff on a regular gasoline-powered RX and the premium for the Lexus hybrid is about $3,000. Factor in a tax credit and the money you'll save on gas, and there's plenty to be said for driving the first hybrid luxury SUV.

Body Styles, Trim Levels, and Options

Available in a single trim level with a choice of front- or all-wheel drive, the Lexus RX 400h is visually a dead ringer for its gasoline-powered RX 330 twin. The standard equipment list includes items such as power-adjustable front seats, stability and traction control, second-row seats that slide and recline, dual-zone automatic climate control and a power rear hatch. Also included are amenities like leather upholstery, a roof rack with rails, a one-touch open/close moonroof, a DVD navigation system with rear backup camera that shows what's behind you, a six-disc CD changer, xenon headlamps that swivel when you turn and 18-inch alloy wheels. Only three items are optional on the RX 400h: a rear-seat DVD entertainment system with wireless headphones, heated front seats and a Mark Levinson audio system.

Powertrains and Performance

In either front- or all-wheel drive, the Lexus RX 400h uses a new hybrid system that combines the standard 3.3-liter V6 engine with three electric motor generators. Mated to a continuously variable transmission, the 400h boasts 268 hp and a 33 city/28 highway fuel economy rating.

Safety

The RX 400h features standard front, side, head, and even driver knee airbags. Standard stability and traction control systems are fully integrated with the hybrid drivetrain, allowing them to anticipate a potential loss of control and react immediately. In NHTSA crash tests, the RX 330 resulted in a five-star rating (out of five) for all but the front passenger, which received a four-star rating.

Interior Design and Special Features

Inside the Lexus RX 400h, three round, chrome-rimmed gauges house the vital information, while the 7-inch navigation touchscreen displays the gas-electric power distribution, just like in the Toyota Prius. Aluminum trim gives the cabin a high-tech ambience. In back, a 40/20/40-split rear seat slides and reclines for maximum passenger comfort. The RX 400h offers 84.7 cubic feet of cargo space as well as a standard power-operated liftgate.

Driving Impressions

Although it's a hybrid, the Lexus RX 400h drives a lot like the RX 330, an SUV we've always liked. Its electric motor may not sound like a V8, but its pull off the line is just about as strong. Ride quality is plush on the highway, and although the hybrid version's extra weight is apparent in turns, the RX 400h remains surefooted. Our only complaint is that engine noise can be intrusive, as the hybrid system gives the V6 more leeway to shoot up to redline under hard acceleration.
