I've been getting the same message as well, on both of my Cap 1 cards (Plat w/Rewards and QS1).
The Plat is a year old, and the QS1 is just about three months old, and on each of them I'm getting the too many inquiries reason. I think my inqs are right around 10, so it doesn't seem like that should be too many, but several of them are rather recent, so maybe that's why.
Regardless, they've definitely tightened things up.
As an aside ... I have a Menards card, which is overseen by Cap 1, and I requested a CLI the other day, but they wanted me to call in, so I did, and they said my request (for an additional $1,500) would require a hard pull. I declined ... kind of seems counterintuitive to request an HP when I'm getting dinged for too many inquiries.
I'm keeping tabs on this issue since I have an unsecured Platinum with a SL of $3,000 opened in February that should become available for a CLI via the "luv" button or telephone call at the 91-day mark after the 3rd statement posts (May sometime with a due date of 6/5) and an automatic Credit Steps increase to $3,500 due after the 6th statement posts (August with a 9/5 due date). I currently have, I believe, anywhere from 6 to 8 inquiries on my various report depending on CRA with the oldest dating from 12/15 (so pretty much meaningless currently given that it's well over a year old) when I got my secured Platinum and the most recent dating from February or March, so that by June those should all have aged by at least 3 months.
