New Volvo front calipers put on in 2018 on my 2007 xc70. Old calipers were causing uneven pad wear.
When I replaced front pads in 2020 there was some of this corrosion starting and I contacted Volvo dealer and received no response.
Last week I replaced pads again and this is how they look.
I sent pictures to dealer from which I bought them-not local, and to Volvo NA. No response from dealer and Volvo NA said to have local dealer inspect them. Local dealer wants $125 to inspect. I can just give them pictures for all the chemical analysis possible at a dealer.
I asked Volvo NA for a charge code to pay the inspection. Who knows?

 

Volvo NA responded
"I can offer you a 30% rebate coupon (up to $200) for the purchase of any parts at our authorized retailers, but labor is not covered by us as they are privately owned and operated."

So I asked,
"Can you send the pictures off to Volvo quality control? The local dealer would not be able to ascertain the chemical cause. I think this is a manufacturing anomaly."

I will drop off pictures at local dealer and see what happens.

 

Do you live by the water? Asking because of potential salt water causing corrosion

 

Dealerships get an attitude if you’ve done the work, even if it’s the part that has failed through no fault of yours.
Good luck
