Rey, You should remember that the user ratings in the Tirerack web site can be somewhat deceptive, as the "user" may not have been able to truly compare the various tire models. I would be more likely to believe Consumer Reports vs users unless a majority of users are reporting problems after a number of miles. JimsGX's experience is a good "sign", though. I wonder why Tire Rack doesn't sell Toyo tires? They used to. This may be another sign.

According to Consumer Reports, the Michelin Primacy MXV4 tops the charts among "H"-rated all-season tires. They are available in 255/55/18 size and have the best rolling resistance rating along with better-than-average tread life. They are fairly expensive at $222 per tire. The Toyo Versado LX is listed among the "T" and "V"-rated all season tires, but did no better than 5th place (V-rated) and 9th place (T-rated). I must say that the Primacy's are also the quietest and smoothest running tire I've ever had an a vehicle. I'm about to put them on an LS430 that I just bought too...

I was at the dealership yesterday and noticed a new RX350 on the showroom floor had the Michelin Latitudes on it...

I put four Toyo Versado XL's on a Lexus LS400 last year and had problems with them. After mounting and road force balancing them at least four times, they couldn't get rid of vibrations / out of balance issues with them. They were 205/55/R17's I believe. I liked the look of the tire, but they just couldn't get them to run true. I ended up with Michelin Primacy MXV4's and have been extremely happy with them. The Primacy's are a much better tire than the Michelin Energy MXV4 S8 tires that came OEM on many of the RX400h's, but I don't think they come in the correct size for the 400h. Michelin Latitude's do come in the 400h 18" size I believe and they have very good reviews on Tire Rack... Tire Rack - Michelin Latitude

Was this a CPO Vehicle or a private party purchase?

Larry, Your problem could be with the trunk wiring harness. In the 1st gen vehicles it's a common problem that causes a lot of weird things to happen like your seeing. Here's a link to give you a little info on it. If you do a search for "trunk wiring harness" you'll find additional info. Trunk Wiring Harness

Given that your in the UK, the spec may be a bit different but on this side of the pond, the wheel definitely locks and there's a switch to disable the passenger airbag. Here's a link to a US 2007 RX400h for sale, the spec's note the ability to turn off the airbag via a switch... 2007 RX400h for sale w/spec's

It may not be saying much for the RX line, but the RX350 is much more capable in snow than the 400h. I didn't realize when I purchased my RX400h that it would be so limited in its AWD abilities. I wasn't expecting it to be like my GX470, I know they're very different animals, but I made an assumption that it would be comparable to the RX350. I didn't have an opportunity to test its AWD capabilities prior to purchase. Hopefully Lexus is working on addressing the problems with the vehicle in this area. In the interim, maybe they should add an AWD disclaimer to the NAV screen at startup and make us all hit the "I Agree" button like we all had to do through MY2007!

This isn't a tire issue, it's a shortcoming of the vehicle. At times, the RX400h won't let you spin a tire when trying to get out of even a small pile of snow. At least this was the case with my previous 2007... I'd floor the vehicle and it would just sit there. No increase in rpm's, no tire movement.

This was one of the drawbacks of the 400h that made me decide to get rid of it after a year. I experinced the same thing and thought it was such a joke that the car wouldn't move through a few inches of snow. I had come from a GX470 to the RX400h, so the 4WD/AWD differences were all too apparent for me. Back into aonther GX and I couldn't be happier...

Since you mention its become louder on the passenger side, you may want to check the EGR pipe. It may be developing a leak.

Try wearing polarized sunglasses. They do a good job in eliminating glare. I've used them for many years when boating.

Hi, You may want to consider some options from this company. I bought four rims from them for an LS400 and I'm very satisfied with the quality of the rims and the price. They have both 17 & 18" rims to fit your RX400h. 5x114.3 I'd call them to verify fitment before ordering. 18" RX Wheel

On your year vehicle I'm not sure. I know the general concept of how all HID's systems work and have experienced this problem with other aftermarket HID's. There aren't too many components to consider. Two ballasts, one or two relays, the bulbs and the wiring harness. In my experience, a ballast malfunction is what made the light go out. Jim

I would suspect that you have a bad ballast.

Leathertech Website I purchased some leather dye from this company and restored the steering wheel on my 91LS. The wheel looks like it's brand new and has held up perfectly over the last year and a half. They have all the instructions you need on the site. My interior is dark gray. They sent me what was supposed to be a match, but it was too light. I emailed them and they sent me out some black dye to darken it up at no charge. Be prepared to sand your wheel. Felt kind of strange to take sandpaper to leather, but its necessary. I also remember using some mineral spirits on the leather before applying the dye. That wasn't part of the instructions, but I did it anyways. Results were great! I've since used it on the drivers seat with the same results. If you end up having to custom mix the color to get it to match perfectly, it looks different when it dries than when it's wet, so apply it to a piece of cardboard, let it dry (use a hair drier for quicker results), then compare it to the rest of the interior. I also found that the tint on the windows of the car and the lighting conditions can affect your comparison. Just mix a small quantity to start and carefully measure so you can replicate it afterwards when you mix a larger batch. I don't mean to make it sound like it was a difficult job. It's actually very easy. Use a foam brush to apply the dye and if you see small air bubbles in the dye when you're applying it, don't sweat it. Don't overbrush it trying to get rid of the tiny air bubbles, they disappear on their own as the dye dries. It will most likely take three coats to complete the job. Drying time between coats is only 20~30 minutes. Jim

Eldor, Thanks for taking the time to post such a detailed review of your car. I sold my 07 RX400h close to a year and a half ago after owning it just a year. I thought the car had some quality issues. I still continue to follow new threads here. I went back to a second GX470 which I'm very happy with. I sat in a 2010 RX350 in the showroom and thought that ergonomically the interior was an improvement, but you never know until you spend some time with it. Jim

Clean the MAF

I replaced mine with Walkers and haven't had any problems with them. They fit perfectly. They're shaped differently from the OEM's but I think each aftermaket manufacturer has their own design.

I do, but I think you already know that! :)

You have something configured wrong. Either on the car or on your cell phones. You need to find the setting that tells the phone/vehicle's bluetooth to automatically reconnect... I had a 2007 400h that worked fine with my Blackberry phone and reconnected automatically. I now have an 08 GX470, and the phone reconnects automatically whenever I restart the car. Your car is fine, it's your service advisor that needs some work.

If my memory serves me, make sure the display shows your odometer mileage and not your trip odometer miles. Turn the ignition key off, press and hold down the button that switches between odometer and trip mileage then turn the ignition key to the on position. Keep it held down for a few seconds and a message will come up on the display stating its resetting the maintenance reminder. I know this instruction is in your manual somewhere too...

Can you tell me which button is the "load" button? I bought my new GX last night and I fiddled with the cd magazine for 10 minutes this morning... I'm assuming you have a GX without Navigation, otherwise the CD loader would be in the glovebox... If memory serves me right, the load/eject button is directly next to the CD slot. Push and hold it for 2 seconds and you'll be prompted to insert a CD. BTW, if you want to eject all CD's, you can push and hold the button for maybe 4 seconds and all CD's will be ejected one at a time. Sorry about giving you the wrong info above. Mine's a newer GX with ML and the CD/DVD in the glovebox is a single feed six disk. It doesn't use a magazine.

I use Shell 93 Octane in my 08 GX and 91 LS400... Both cars run better on it than other brands of fuel I've used in the past. Shell puts a lot of detergent in the fuel. I get 19 on the highway and 16 or so in the city. Top Tier Fuel Companies
