NHTSA Complaint #11602157 — 2013 LEXUS GS

I own a 2013 GS350 RWD BASE MODEL. I have been having issues with the steering in this car since it was purchased in 2021 with100k miles. It seems to do great at lower speeds or on curvy roads, but when I drive on interstate going straight at around 70 to 80 mph is where it really becomes noticeable. The vehicle does not want to drive straight for anything. It does not pull in one certain direction; it is literally all over the road. I'd like to note that i have new shocks and upper shock mounts in the front, as well as tires all the way around, also replaced the sway bar linkages on the front and did an alignment. But the vehicle will veer from left to right with no rhyme or reason so bad that you cannot take your eyes off of the road to even adjust the ac or radio from fear of running into the concrete barricade or another vehicle. Something I'd like to add is that it really becomes prominent after about 10 to 15 min of interstate driving. I have taken it to two different Lexus dealerships and called Lexus directly. No one seems to know what I'm talking about; the first dealership told me to replace all of the parts that I previously mentioned. So, I did with no success. I have seen other GS owners complain about this online, so I know it is not just my car. This to me is a major safety concern because it had almost caused me to have several accidents personally not to mention it's just extremely annoying to buy a Lexus and to have to constantly pay attention and adjust the steering so as to not destroy the car and hit or hurt another driver. I always feel like I am going to get pulled over for a DUI. That is how bad it is. I own a 1999 Toyota corolla and that car is effortless to drive straight, I do not have to even think about it. I hope this in some way will help another GS owner to know that you are not alone if you experience this issue and maybe enough of us can cause Lexus to do the right thing here. THX, unhappy GS owner
