I have seen two used vehicles( Lexus of R.I.) for sale with 6 and 8 aligments done already. Is this a signal something is not right?

 

I have not had any issues with mine nor have I seen of any. Might be an anomaly.

 

First time i’ve heard of this. Maybe the drivers are hitting potholes or are taking sharp turns?

 

"Taking sharp turns" won't cause you to need an alignment. Unless you took a sharp turn into a curb.

Could be just a picky customer who "swore" his car was pulling left or right. Drive the car and see for yourself. Chances are pretty much 0 that a mass produced high quality car such as a Lexus would actually have such a defect. I'm guessing just a customer who doesn't really know how cars work kept complaining to Lexus that they "better fix his car or else"
