Q: Car follows road aggressively and the steering feels loose and wobbly.

Hi Sean. Thanks for contacting us today. I don’t think Lexus is lying to you for some reason - more that they simply don’t notice what you are feeling in the car. If anything, the dealership would want to find something wrong so they can charge you for repairs - as nothing would likely be covered under warranty after 5-years. If you’ve recently replaced tires or if for some reason they were rotated from left to right (which I believe those are directional and can’t be rotated), then this could explain the loose steering you are feeling. Loose or damaged wheel bearings can also produce a driving issue as you’ve described - as can a loose strut mount or stabilizer bar bushings. Brakes and pads shouldn’t impact the driving or handling characteristics of a vehicle, so I don’t think that has anything to do with the symptoms you’re describing. Anytime aftermarket components are used to replace OEM parts, steering and handling changes can occur - without having any mechanical faults. Perhaps that’s what is happening with your Lexus - but without inspecting the vehicle or driving the vehicle personally it’s simply not possible to provide you with an accurate reason. You might want to consult with a Lexus-specialty repair shop to see what they can find.
