20230620SUSPENSION

The tires keep coming out of alignment which causes vehicle vibration, a pull to the left and premature wearing of the tires that then have to be replaced every 10-20K miles. Lexus is aware the IS series cars wear tires this way but state its bc this is a high performance vehicle. The vehicle vibration and driveline issues can get bad enough that it could pull a vehicle into a different lane potentially causing an accident. Had it into the Lexus dealership 6+ times for this and after replacement of tires (on 2nd visit) to the recommended tires for my vehicle, it still keeps happening. Then I take it in again and again, technician still can't find an issue and then they just rebalance and align the tires again. Then it's out of alignment again within a week to week and a half. Found out not long ago that the original owner also reported this EXACT same issue at 5K miles. Manufacturer has not inspected it to my knowledge but TONS of people in the clublexus.com forum mention this
