BYD e6 common problems and how to fix them (2023)
4 min read·Last updated: 2023-01-01·By ev.care editorial team
TL;DR
The BYD e6 has 5 commonly reported issues — none catastrophic, all well-understood. Most are software or wear-item related and resolve on a single workshop visit. BYD the country's service network handles them under warranty; out of warranty, repair costs are predictable.
Every EV launched since 2022 has had its quirks, and the BYD e6 is no exception. BYD the country's engineering teams have addressed several of these via OTA updates, but if you are buying a used BYD e6 — or a new one off an older production batch — these are the 5 issues most likely to show up in the first three years of ownership.
What BYD e6 owners report first
BYD e6 units from the first production year see this more than later ones. Issue 1 — Suspension harsh when empty. On the BYD e6, 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 — Infotainment is dated. On the BYD e6, 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 71.7 kWh, 520 km electric mpv like the BYD e6, these patterns are well within what the platform is designed to handle once the right service-bulletin steps are followed.
More BYD e6 fault patterns to know
On the BYD e6, this is one of those faults that is easy to live with but worth fixing properly. Issue 1 — Range drops 15-20% in extreme summer or winter conditions. On the BYD e6, 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 — Charging connector pins need occasional clean for full speed. On the BYD e6, 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 71.7 kWh, 520 km electric mpv like the BYD e6, these patterns are well within what the platform is designed to handle once the right service-bulletin steps are followed.
Quieter BYD e6 issues that still matter
If your BYD e6 is from an early build, this is one of the first things to check. One of the most discussed issues is "12V aux battery worth checking annually" — and on the BYD e6 this typically shows up as inconsistent behaviour that an experienced technician can replicate on the lift. For a 71.7 kWh, 520 km electric mpv like the BYD e6, these patterns are well within what the platform is designed to handle once the right service-bulletin steps are followed.
Practical next steps
When booking BYD e6 service, mention the specific symptoms by name. Modern EV diagnostics are very good but they only diagnose what they are told to look for. Citing the fault patterns in this guide shortens the troubleshooting loop.

Frequently asked questions
- Does BYD e6 warranty cover these issues?
- Most of them, yes. The factory warranty on the BYD e6 covers powertrain, battery, and electrical defects, and the brand has been generally responsive to the patterns in this guide. Document everything in writing and keep your service records.
- How long do BYD e6 repairs usually take?
- Software fixes are same-day. Suspension and trim work is usually one workshop day. Anything involving the high-voltage system can take 3–5 days because parts get ordered from the brand's central warehouse — plan around it.
- Do these problems hurt BYD e6 resale value?
- Only if they are unaddressed. A BYD e6 with documented fixes and a clean inspection report holds value almost as well as a fault-free one. What dents resale is the absence of records, not the presence of a repaired issue.
- What if my BYD e6 issue isn't in this list?
- Talk to ev.care. We see BYD e6 cars every week and the long tail of one-off faults is real. The advantage of a brand-agnostic inspection is that we have no incentive to dismiss anything.
The BYD e6 is not a bad car because of these issues — it is a popular car, which is why patterns are visible at all. BYD keeps improving the platform with each refresh, and the secondary market for BYD e6 parts is healthy enough that even out-of-warranty fixes don't break the bank.
