Love it, but it does

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

This has been the best car I've ever owned, however, I have never gotten more than 21 MPG. Beyond that, there are no cup holders for those in the back seats, which I never thought of until it became an issue. The navigation system takes too long to start & the update ($500) I paid for after a few years didn't include any noticeable improvements. In my 6th year, as well as this, my 7th year of ownership, I have experienced a new issue with the door to the gas cap sticking, with an annoying wait while gas visibly escapes to relieve pressure in order for the door to open. The dealer tells me this is normal, but it is new to me in all of these years. Its a fun car to drive but with flaws.




Long term review 2006 lexus

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

Long term results report. I had my invertor replaced september 3, 2010. So far it has been bullet proof. Toyota fixed this $10,000 repair for free. Basically it is a faulty invertor , recall # 87559 June 29, 2011. This was at 64,000 miles and I am now at 96,000 miles with everything working well. I had to do the timing belt, tensioners, water pump , as part of the recommended 90,000 mile maintenance. I also had to do a radiator and front control arm bushings so this was a major bill. I did switch tires to Yokohama Parada's so the car rides very well but thye are not the longest lasting tires. Gotta figure if there is a cheaper way than a lexus dealer. But in thinking of doing all this work I decided this is a overall very reliable car and worth doing as the car rides well, looks good, and is nice to drive. I figure the Prius 's I have seen used as cabs are going over 300,000 miles so there is some precedent for long term ownership. Yes I would buy one again ( and I guess by fixing it I am planning another 90,000 miles , I hope ! )




Actual gas mileage = false

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

Our gas mileage has never been as advertised. We bought our RX400h with 8000 miles on it in Sept 2006. It was 1 yr old, the prior owner traded it in fast and took a $20k loss on the trade in. We have always averaged 26.2 mpg in a mix of city/hiway driving. We had the hybid inverter module replaced in Feb 2012. $10k+ repair! Our gas mileage then plummeted from 26.2 to 23.4 mpg. We suspect that Lexus reprogrammed the engine management computer to use the gas engine more and the hybrid less so as to extend the life of the batteries and inverter. This way, they won't have to make so many expensive warranty repairs. Please let us know if you saw the same thing with your mileage.

I am stumped

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

I love my Lexus RX 400h and I have already driven it 98,000 miles. But the number of service problems that have been coming up recently are very frustrating. The criuse control died, the battery died, the radiator was leaking and had to be replaced, (not a single drop of coolant on the garage door) and just yesterday the timing belt, the pullies and the water pump had to be replaced too per Lexus request. More than $2500 in less than a year. Is my beloved SUV falling apart or is this a conspiracy !!! I bought my SUV brand new in May 2005 and I feel that I am suffering through the deficiency of it being the first year model in this series.

Big ticket repairs

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

Last year while far from home my RX400h stopped dead on the highway. After having it towed 145 miles and losing 3 days of vacation, Lexus replaced the computer to the hybrid system. The car was under warranty so other than a LOT of hassle, it only cost me $150 not $10,000+. Two weeks ago, I was driving in town and my car died again. Luckily I was able to get the car over to the side of the road--all the systems died. After about a week of trying to figure out what was wrong, Lexus determined it was the inverter and gratefully, even though out of warranty, the dealership replaced the part ($10K+) for free (98K miles on my Rx). My gas mileage has never been much more than 24-25mpg.

Amazing vehicle.

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

This Vehicle is the Best suv to own hands down. For those of you who own one or have driven one, you know what I'm talking about. Awesome look, feel, ride, and reliablility. I will never consider owning anything other then lexus for those reasons listed above. The thing moves! Very very fast like a v8, but with 4cyl. effieciency. Gas mileage is great! 26-29 overall. For a vehicle weighing in at 5000 pounds and AWD, you would be crazy not to think that it was fuel efficient. If there were a negative review on this vehicle it would have to be from another car manufacturer because they just cant handle quality like this. Take care of your vehicle and it will take care of you!



Full 2006 Lexus RX 400h Review

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.
