Like all my AWD vehicles, I took my 05 GX470 out to a empty parking lot on the 1st sign of snow to test what the AWD can do. I remember being amazing on how good the stability system works on the 05 GX, everytime I slide just a bit, the stability system cought the back end and put the truck back into a straight line, it was almost like its on rail.
I sure hope it is just a matter of programming the stability system to be more sensitive, but from my pass experience of how Lexus' stability programming always plays it safe, unlike German cars, I think there might be something more going on here. Perhaps they deleted one of the sensors, maybe they are using a cheaper vendor for some of the components in the stability system, I am just guessing at this point.
CR did give the Acura SRX and the Isuzu Trooper high roll over possibility warnings. I am very surprise the Rover LR3 is not on the list, I seen a few of those on its side a couple of times.
