As a popular model among Chinese electric cars and hybrid cars, the 2023 BYD Han DM-i generally maintains good reliability, but some common problems reported by owners include occasional seat sagging/creaking, unintended engine activation in EV mode, and minor steering wheel paint peeling. High-speed wind noise and larger turning radius are also noted by some drivers. However, these issues are mostly non-critical and come with low maintenance costs. The vehicle's powertrain system has proven mature with low failure rates, making it a reliable used car choice—well-maintained units can sustain stable performance over long-term use, which is a key factor for anyone looking to buy used cars.
