Have had the truck for a few months and overall, we love it. The biggest issue by far is the inability of this car to track straight on any road with a slight slope for drainage. It tracks incredibly straight on some roads with no road crown, it is terrible on almost all other roads, especially highways. I have got the alignment dialed in, it is perfect, tires are good and correct PSI, etc...
Surprised at this...I know lots of high performance cars do this, but not such a comfortable cruiser? Any insight would be appreciated.

 

same thing on windy days.

 

Agree, I find it pretty bad on windy days as well.

 

F80Dreamer, you are not the only one who encounters this problem. A lot of us here have the same problem. My 17' and 18' GX have the tendency to veer to the right on flat surface road. Like yours, mine have perfect alignment, tire pressure, and correct tire balance.

 

Ok thanks for the reply...have you taken it to the dealer to try and find a solve?

sorry if this topic has been covered, I tried searching but couldn’t find anything.

 

I took it in for service twice. Both times they claimed that it's within spec. However, they acknowledge that it's a common issue. The solution is to replace the springs if it's out of spec. I test drove several 17' and 18' GXs and notice that they are all leaning to the right with slight variations. Here's the thread that discussed exclusively about this issue

We had the same problem on our 2015 GX too. I kept returning to NTB and even took them on test drives. Unlike the Dealership, they were not aware of it being a "common problem" so they continued their effort to get it resolved. They made a small change to the passenger side caster...hallelujah. Okay is it perfect? No, but it tracks so much better that it is no longer a nuisance. If there is a road crown, you still get a very slight bias to the right but otherwise it tracks perfectly.

I'm in McKinney. If you live nearby you are welcome to take it for a drive and/or I will certainly share the location of the NTB that got ours resolved.

 

Thanks, I am in McKinney as well! Yes pls share the store location so I can get it checked out. It’s pretty frustrating.

 

Awesome! The NTB on Custer Road just north of 121 (next to the Sonic and Wave Wash).

Here's a copy of the alignment notes, unfortunately the technicain didn't print his name on the report.

 

Not sure if all '13s but stating during that model year they went with a few different components in the steering rack because some owners had reported some shimmying in previous model years. I haven't seen that in mine...but saw some threads here that this change meant GX wouldn't track as straight down the road when there were crown issues.

Looks like it was '10-'12 so rack valve mod must be all '13+.... seeing this came out 3/2012 there are some latter model '12s that have this change as well. Mine was built in 2/2012 so I have the old rack setup.

I don't have issue with veering left/right on uneven roads but could feel the high wind pushing around especially around 70/80mph

 

Just a question/comment...several of you folks are saying your tire pressures/tires/etc. are good-perfect...You realize the correct tires/tire pressures depend on a number of factors including driving style, road conditions, temperature, etc. The "Lexus recommended" tire pressures are the average for all types of conditions. Which means half the time there is too much pressure and half the time there is not enough pressure for the conditions. You might have to experiment with tire pressures to get the ride you want.
