That's because I called Chase and requested roadside assistance, a benefit on my Chase Sapphire Reserve® (see rates and fees). This, I decided, would be a great time to test out Chase's roadside assistance benefit. How to initiate roadside assistance with a Chase cardTo initiate roadside assistance, call Chase's card benefits services line. Note that many other Chase cards also offer roadside assistance, including the Chase Sapphire Preferred® Card (see rates and fees) — but you'd need to pay "a pre-negotiated, per service fee" to utilize the benefit. The site is used for most other claims, including car rental coverage and trip delay reimbursement, but not roadside assistance.
