Seal vibration / noise

I have a similar problem in Han. I will visit byd next week to revise it.

Another case here too. I've just bought a BYD Seal and after 20km I immediately noticed a noise/vibration near the steering wheel (In my case it's around 50km/h when I turn right). I don't know if it's coming from the steering wheel, the HUD or another component, but it's quite noticeable.

I have my seal now for 4000km and have the same problem since the start. The garage has set up 4 new tyres and de sound is less but it is still there. Did they find a solution with your cars?

Hi everyone, I wanted to share my detailed findings about a buzzing noise and steering wheel vibration issue that I’ve been experiencing on my BYD Seal AWD currently at ~2,000 km. After weeks of testing, I’m hoping this helps others who may be facing something similar. Symptoms: Buzzing sound triggered mostly between 25–40 km/h, especially on porous/grainy asphalt or concrete expansion joints. The vibration is most strongly felt at the top of the steering wheel and on the plastic trim near the multifunction switch behind the wheel.

Sometimes it doesn't trigger at all, depending on the day/route. The issue began early (under 100 km), and is intermittent but frequent. Technical Findings: Using Spectroid and Audacity, I found that the buzzing seems to resonate consistently at around 211 Hz. I also recreated the tone using audio generators, and noticed that the dashboard area vibrates slightly when that frequency is played through the car’s speakers. The rumble is always present in some form (even without the buzz), and shows up in spectrograms clearly in the 200–250 Hz range. Affected frequency often shows up at around -40 to -25 dB, depending on road surface. What I’ve Tried: Took the car to a BYD dealership twice: First time: no work order opened; couldn’t reproduce the sound. Second time: left the car, mechanics test drove it multiple times and inspected the airbag module per my request, but found nothing. Work order closed. Played tones in the car (via speakers and Bluetooth) to try to replicate the buzz – dashboard parts vibrate, but no buzzing was triggered artificially. Other Owner Reports: After sharing a video and description in group for Seal owners in my region, another owner confirmed he had the exact same issue, and knew of two more cases: One had the entire HUD replaced after disassembling multiple panels on a dealership. Another applied silicone to stabilize a lens or bracket inside the HUD. That owner also mentioned hearing a lens or mechanism inside the HUD move after power off, possibly explaining why the buzzing stops after turning off the vehicle. My Hypothesis: The HUD unit may contain a loose optical part or mounting bracket that resonates at specific frequencies, especially when warm or after expansion. The steering column trim may just be conducting or amplifying the vibration. Alternatively, it could be related to a steering rack or EPS resonance, but so far the HUD is a strong suspect. Why I’m Posting: I’m still trying to confirm the exact source without dismantling the whole dashboard. If you’ve experienced this, please share your experience or any dealership feedback you’ve received. Another forum post in my region confirms they traced to the HUD unit, that before they replaced the whole HUD unit, but now they know how to fix the unit and repair it. The whole service takes one day. However as we stated, it needs taking apart dozens of panels of the whole dashboard, and the worry comes from fixing one issue and introducing another ten issues. According to the Seal Service Manual, there's a lot of internal components to be disassembled, the whole center console, the side panels, the instrument cluster, the big PAD screen, the air vents, the auxiliary panel trims, all that to eventually reach the hud that is deep buried into a puzzly maze of trims, all at risk of being scratched, having damage, broken clips and plastic fasteners, and so on.
