TL;DR
The Xiaomi Auto SU7 has 4 commonly reported issues — none catastrophic, all well-understood. Most are software or wear-item related and resolve on a single workshop visit. Xiaomi Auto's service network handles them under warranty; out of warranty, repair costs are predictable.
Every EV launched since 2024 has had its quirks, and the Xiaomi Auto SU7 is no exception. Xiaomi Auto's engineering teams have addressed several of these via OTA updates, but if you are buying a used Xiaomi Auto SU7 — or a new one off an older production batch — these are the 4 issues most likely to show up in the first three years of ownership.

Xiaomi Auto SU7 units from the first production year see this more than later ones. Issue 1 — Production ramp constraints — wait times of 6+ months reported. On the Xiaomi Auto SU7, owners typically notice this within the first 12–24 months. The diagnosis path is well-mapped: a connected scan tool reveals it quickly, and the fix is usually a documented service-bulletin procedure rather than experimental work. Issue 2 — Real-world range 15-25% below rated figure on highways with AC. On the Xiaomi Auto SU7, owners typically notice this within the first 12–24 months. The diagnosis path is well-mapped: a connected scan tool reveals it quickly, and the fix is usually a documented service-bulletin procedure rather than experimental work. For a 101 kWh, 800 km premium electric sport sedan like the Xiaomi Auto SU7, these patterns are well within what the platform is designed to handle once the right service-bulletin steps are followed.
