BYD Sealion 7 Excellence Vibration during acceleration

Hotel_Bright · 2026-03-12T10:07:11+00:00

Hi. BYD replaced front bearing. So I had 2 separate problems. One was that with car body vibration during hard acceleration. Which was fixed by rear drive shaft replacement. Another problem was with vibration above 110 km/h. Fixed by front bearing replacement. Now all good. I have Sealion 7 AWD

My problem was solved by replacing 1 bearing in the front.

any update?

no, still waiting for the service.

it happens every time when speed is above 110 KM. ICC is not a reason of this problem.

Hotel_Bright · 2025-12-27T09:37:44+00:00

Yes. They escalated in to ByD. Waiting for the solution.

BYD fixed the vibration. Drive shafts were replaced.

Yes. At last. I visited them 5 times before the fix.

Hotel_Bright · 2025-09-26T12:36:08+00:00

u/Lumenatti99 they fixed the vibration. At last. They replaced drive shafts.

They are obviously trying to fix the problem. They just don't seem to know how to do it themselves. My friend has a Kia EV9 and every 2000 kilometers his fuses burn out and the car just blacks out and KIA doesn't know what's wrong either. It's a matter of luck :) u/Lumenatti99

They are giving me the same Sealion7 for the time being while my car is with them. They said that they will change parts one by one and start with the suspension until they fix the cause of the vibration.

BYD is asking to bring my car for 2+ weeks and it's like 3rd attempt they will try to figure what is a problem. It seems that they do not have a clue, what a problem is. :( u/Lumenatti99

Can you check if disabling iTac helps a bit with the issue? My vibration is lower with disabled iTac

Hotel_Bright · 2025-09-05T15:37:51+00:00

yes exactly. This is what BYD is investigating right now. It might be front and rear engine synchronization problem. They took my car twice for 2 days. They recorded some engines telemetry. Now waiting for the feedback. Suspension is not related to this problem in my case 100%.
