Hello everyone,

I am thinking about buying a 2006 GX470 for my wife. I've been reading alot of reviews and forums, and one issue that bothered me is the stability of the truck at high speeds. Any truth to that? I read that above 65-70 MPH , that the truck is not very stable.

Thanks in advance

Welcome to the forum!

Now we all know that we are going to obey the speed limit laws of our own states, correct?

Running at about 70-75mph, it really depends. First of all, is your wife coming from a car or minivan, which both have a lower center of gravity? If so, at first it may feel unstable as an SUV really drives differently than a car or van. Secondly, if you take gusty winds as a factor (which I'm not sure if that's common in your area) then an SUV will feel really unstable to drive in gusty winds.

Now if your wife is coming from a different SUV, then the GX feels very stable in any scenario. It just takes a little getting used to the vehicle. Otherwise, since the GX is top heavy, it is "stable" even when running at about 70-75mph and even with gusty winds.

65 to 70 MPH is ok with the GX if there is no cross wind, but it can drift a lot with a strong cross wind at that speed because of the GX's boxy design. The RX350 in comparision is much better SUV at high speed in the cross wind. And then there are performance SUV such as the X5 which the cross wind doesnt affect it at all.

I would say over all, with no wind, the GX feel pretty stable up to 75 MPG, after that it take a bit of attention.

We've owned a 2003 and 2005 GX 470. We live in Texas and drive back and forth to New Mexico 9 or 10 times a year. We've drive through very high winds and dust storms as we go through West Texas and New Mexico. The GX is very stable and holds the road without a problem. We've driven betwen 75 and 80 (on interstates with this speed limit) with no problem. We have a RX 350 AWD and notice very little difference between the two...both are stable on the road. Like any SUV, I'm sure a quick 90 degree turn could be a problem at high speed, but that's a problem with any vehicle and it should not happen. Also, we've driven on four wheel drive mountain roads in Colorado. It's very stable there too. Hope this helps. By the way, we will buy another one soon. We think it's a great SUV, but you pay the price for it. I just wish Lexus would go with the Michellin Cross Country tires (they are on our 2005) instead of the grocery store Dunlop AT20or Bridgestone HT tires.
