Are they considered struts or shock absorbers?
I took my IS250 in for repair and was told the rear struts needed to be replaced. My warantee company covers struts, but when the mechanic called the claim in they were denied, they said because the warantee doesn't cover shock absorbers. I've been back and forth with the company, and I even called Lexus manufacturing and was told this part that needs to be replaced is a strut that also does the job of a shock absorber, so technically it is both. Which is it? If it is in fact a strut, I will go to battle with this company, but if it really is just a shock absorber then I guess I'm screwed and will pay the $900 they are saying I need to pay.

Lexus uses Double Wishbone Suspension in the IS Series. That uses Shock Absorbers:
https://en.wikipedia.org/wiki/Double...one_suspension
McPherson strut Suspension uses struts:
https://en.wikipedia.org/wiki/MacPherson_strut
However, since the Shock Absorber performs the same function of the Strut in their various suspension configuration, there is absolutely no reason that your claim should have been denied.
The only struts on your car are the ones that hold your hood open. Whoever you spoke to at Lexus Manufacturing was dead wrong

The rear suspension in the IS is a multi link setup that uses shocks with the coil spring mounted on them similar to how a strut setup would be. In the loosest sense of the term they are very similar, but not identical.
When referring to a "strut", typically what is being referred to is a MacPherson strut. The biggest difference is that a strut pivots with the wheel and a shock absorber does not. (In a front setup, this will pivot with the steering, on a rear setup it typically only pivots when adjusting the toe for an alignment).
A strut has a shock absorber as a component of the assembly, but a shock absorber is not strictly a strut (in the way that they would be referring to it).
As flowrider said, there are no "struts" on your car (front or rear), even though many people may call them that colloquially.

Whom is you warranty company? Have you ever received in paper form or in email a full detailing of what all your extended warranty covers? Need to pinpoint their verbiage in their own writing to bring to their attention.
They're just looking for ANY reason to not cover your claim.
