Below is the experience of a French user after installing new engine mounts. This post can be found on the French Xpower community page:

INFO POSITIVE VIBRATIONS
Summary of the situation:
My XP from October 2023 experienced the vibrations described by several of us.
It started vibrating at 70 km/h, and after replacing the steering damper (a mandatory step), the vibrations in the steering wheel decreased and instead appeared at around 90 km/h. This intervention clearly showed that it wasn’t just the steering wheel vibrating, but the car itself.
I also noticed a sort of rumbling sound inside the car.
Following the release of the MG technical bulletin, I forwarded it to my workshop, MG Cavallari in Nice.
To the great surprise of the workshop manager, there was no trace of this bulletin in France, and he expressed frustration about learning of it from a customer instead of directly from MG.
This workshop had already dealt with a vibrating XP at low speeds in early 2024. The owner returned less than a week after delivery, stating the car was undrivable. According to the mechanic, “it was impossible to drive like that.” Their diagnosis identified a failure in the engine mounts, which MG accepted under warranty, and the results were positive. The customer was satisfied.
I suspect this prior experience in the Nice workshop helped my case to be approved by MG under warranty, given the technical bulletin supports this diagnosis.
To my knowledge, no one else in the group has had a warranty approval for this issue so far.
Nice was waiting for my feedback to confirm whether the intervention was successful or if they needed to proceed with step 3—replacing the subframe if vibrations persisted.
This was completed today. After testing daily over a week, including at speeds where the vibrations previously occurred and even at high speeds on a familiar road (up to 160 km/h), I shared the following conclusions with the workshop:
- First point: The rumbling sound during daily driving has disappeared, except on rough roads, where I believe it's just feedback from the wheels over uneven surfaces.
- Second point: The car no longer vibrates at all, as confirmed by me and the technician who tested it with me and had previously noticed the vibrations before the intervention.
For your information, I’m no longer using the original tires.
The workshop will now report back to MG France, which I assume will validate this solution. However, I’m not sure how long MG will take to process their feedback—it’ll probably be at least another week.
In the meantime, you can share this information with your respective workshops.
I haven’t yet received an invoice or intervention report, as I assume it will only be issued once the warranty case is officially closed.
If MG rejects the warranty claim despite these findings, your workshops can contact Nice directly using my name; they’ll know which car it is, given how many times I’ve been there. Fortunately, I live nearby.
That said, I don’t know if Nice will respond to everyone due to their busy schedule, so your workshops should start by reaching out to MG France first.
In the photo, you can see the old engine mounts, which I’ve numbered according to the technical bulletin available in the group files. I couldn’t upload it here with the photo.
