I've had my original one since 2014 (so currently 9ish years) and it hasn't missed a beat other than needing to replace the cookie paddles a few times. But the motor itself has been a powerful beast. Once upon a time (I can't remember where), I read that a Bosch rep said the average lifespan for the mixer itself is over 25 years! Currently, the mixer motor and parts (inside) have a 3-year warranty and the attachments have a 1-year warranty.
