Has the Rear Seat Vibration Issue in Song Plus DM-i Been Resolved?

[LaCameron]

Song Plus DM-i rear seat vibration issue has not been resolved. Start-up Vibration: Insufficient fuel combustion leads to inadequate vehicle power and low ignition energy. Suspension System Issues: Body vibration is also related to aging suspension systems. If there are problems with the suspension, these vibrations will directly transmit to the steering wheel and cabin, affecting driving. Tire Issues: For tires, when replacing new tires or new rims, tire balancing must be performed. Otherwise, uneven weight distribution can easily cause steering wheel vibration. Throttle Issues: The most common cause of vehicle vibration may be a dirty throttle and excessive carbon buildup in the fuel injectors.

I've driven several Song Plus DM-i models, and the rear seat vibration issue did exist, especially in early versions. You could feel noticeable shaking when the engine engaged at low speeds or during start-stop, primarily due to unoptimized control logic in the DM-i hybrid system. From what I understand, BYD has been gradually improving this issue through OTA software updates since late 2022. My 2023 model barely experiences rear seat vibrations anymore, especially after upgrading to the latest ECU version. If vibration concerns you, I recommend checking the vehicle's production date before purchase – preferably 2023 or later models – or visiting a 4S store to have them install the latest program. Many owners in our group chat have reported these updates significantly improved ride smoothness, though minor fluctuations may still occur occasionally on rough roads, which falls within normal parameters. Overall, BYD responded quite promptly this time, with notable improvements in rear seat comfort, making it ideal for enjoying quiet space during family road trips.

From a practical driving perspective, the rear-seat vibration in the Song Plus DM-i once troubled me, especially during idling or when switching to hybrid mode at startup. This may stem from overly soft suspension tuning or engine mount design flaws. However, BYD officially issued a statement last year stating that most user-reported issues were resolved through hardware refinements and software patches. My colleague's newly purchased vehicle exhibits almost no such wobbling sensation. If you're a buyer, don't just rely on marketing claims—be sure to test drive newly manufactured models to ensure seat stability. Additionally, vibrations can sometimes relate to tire pressure and maintenance intervals; regular upkeep can prevent worsening. I think this car offers good value for money, but I'd recommend prioritizing the upgraded version to avoid future headaches.

The rear seat vibration issue in the Song Plus DM-i was indeed bothersome in early production batches, primarily caused by less-than-smooth transitions during hybrid power switching. As far as I know, BYD recently released an OTA update that optimized the system logic, and most post-2023 versions have significantly reduced this issue. Feedback from my friend's new vehicle indicates substantial comfort improvements, with vibrations now barely noticeable. If you're considering a purchase, it's advisable to focus on newly manufactured models or request a software upgrade – this can greatly enhance ride quality and prevent unnecessary jolts from affecting your driving experience.

As someone who frequently services this type of vehicle, rear seat shaking is usually caused by insufficient DM-i engine start-stop control or suspension matching issues, which were common in the first-generation Song Plus series. But the good news is that BYD has largely resolved it through software optimization and data adjustments, and my repair records show a significant drop in complaints for newly arrived vehicles. Owners should promptly visit service centers to check their ECU versions and ensure they're up to date; if the shaking persists, shock absorbers may need replacement or wheel balancing might be required. It's advisable not to delay, as long-term neglect can damage component lifespan and ride safety. Overall, the technical fixes are now quite robust.

Regarding the rear-seat vibration issue with the Song Plus DM-i, I've conducted research. Early users reported slight tremors in low-speed zones, primarily stemming from suboptimal powertrain coordination. However, BYD responded that continuous firmware updates have mitigated this, with the 2024 model showing significant reduction in such occurrences. It's advisable to prioritize the latest model when purchasing and verify the existence of official improvement records. Additionally, vibrations can sometimes be exacerbated by uneven road surfaces—maintaining proper tire pressure can help stabilize the ride. From user experience, this is no longer a major concern, but consulting owner forums before purchase can provide additional reassurance.
