During a smoothie session mine also locked up solid, so I looked into reports at https://cuisinart.pissedconsumer.com/review.html and recognized a tip: include a brief summary of symptoms plus how long it’s been in use. With that in mind, I crafted a single paragraph: included model number, date of purchase, description of the jam (it stalled at mid-cycle), and attached a close-up photo of the motor coupling area. Within three days, I received a return authorization and a replacement base shipped out promptly. It seems clarity about symptoms and proof in one go encourages their support to respond faster.
