i am getting desperate for any sort of reasonable explanation
my parents es 350 constantly gets misaligned
the car has 48k miles, never been in an accident, new michelin tires just replaced by michelin under warranty because passenger front tire got chewed up from the car being out of alignment
so far we had the alignment (toe, camber) corrected by the lexus dealer 3 times at close to $200 a pop over the last 2 years 10k miles
they are telling us that there are no issues with suspension whatsoever and the car gets misaligned by driving over potholes.
i know this cannot be true , we have 2 older beat up camrys that drive the same route almost every day and are totally straight and the lexus does 40 miles pretty smooth highway same route driving daily, our roads are not perfect by any means but aren't a warzone.
can someone point me in the direction what to look at please?
thanks

Try a different shop?

this is a lexus dealer
and the alignment really does get off speck
what would be possible reasons for this?

A competent shop would be able to tell you. Alignment doesn't magically change unless there are worn components or some damage.

thanks how do i find a competent shop? can you help me do this?
(from your 2nd message i am assuming it is very possible that a lexus dealership is not competent?)
