I bought a CPO DB11 Volante with 5k miles and after 1500/2000 miles of driving I am getting this issue - violent shuddering of brakes when braking from 60mph down to about 40mph. I had a major service done in March (bought car last August) and reported the shuddering then. Dealers response was to balance all wheels and replace 2 x rears (charged for, which made zero difference). Took car back in a week ago, saying problem never fixed (and reached out to AM North America Customer Service).
Dealer's tech accompanied me on test drive to see/feel the shuddering (which they confirmed, and told me in car that is was 99.9% brake discs and pads issue)
Car is still at dealer as their warranty claim for rotors/pads was allegedly rejected. I am incensed by this as customer service response was that I should take Volante back to dealer and have them swop out tires and wheels with another DB11 to see if this made a difference
My dealer said they would have to charge for several hours of diagnostic labor etc - this is 100% unacceptable. Plus the suggestion of swopping wheels/tires wouldn't even be acceptable on a Prius...
I had previously owned a 2019 Vantage which was an ownership disaster from day 1, and thought after 3 years I would buy the DB11 as a CPO with peace of mind. Wow was I mistaken. I thought any work that was due or observed within 3000 miles of purchase was to have been covered by CPO, and wasn't expecting a debacle over what should or should not be covered (by the way over $6k for replacing rotors/pad is the quote (after paying $6k for the major service 1500 miles after purchase)
A complete lack of interest in customer retention/service ...not much else I can add.
