And for the last year or two the part # is 11718576450. Hopefully the different design changes were made to reduce the incidence of cracking. So maybe you had the earliest (and maybe most failure prone) design? And maybe some consolation might be that you'll be putting in one less prone to failure.

Here is the reference on RealOem:

I assume this would apply to your Canadian car as well, but not sure.


Hope the info is helpful.
