MG4 X Power Vibe/Hum 65 to 75mph

[jamherber]

Is there any consensus on what years have this problem? Will a 2025 if they exist still exhibit the same symptoms?

General consensus seems to be cars manufactured 2024 onwards seem to generate less complaints (although there are still some). Trouble is, they aren't big sellers so often cars registered up to late 2024 can actually still have a manufacture date of 2023.

The Certificate of Conformity will show manufacture date but as mentioned above, it's no guarantee. If you are buying 2nd hand, only way to be sure is to drive it yourself above 66mph and see if you get a 'buzz' through the steering wheel and chassis, before committing to purchase.

Have a look from here, where I asked the same question.

I don’t think there is. It’s just pot luck.

The ‘fixes’ are applied at the factory since February last year but they don’t always work. Mine does it mildly now but was terrible at first, and was built after they started being applied at the factory. Someone on here recently had the stage 2 fix done at a dealership and it didn’t work.

So MG UK are still selling Xpowers knowing there is a vibration (that once warranted a Technical Bulletin Fix for it as a Fault) but not telling any prospective new buyers .

There’s an interesting email allegedly from MG UK to a customer on the Facebook Group outlining this decision :-

So in other words tough shit. We ain't doing owt about it. But we knew that anyway. As a side note though, I wouldn't read to much into what Fakebook says.

Is that recent sounds really something that was posted a while ago, UK owner was getting the fix until they (MG) changed their mind

I agree that this is old message from MG that was discussed at length months ago.

It seems they have not done anything further - at least they haven't said that they have.

I think it’s old but if true it states there were some high up meetings to come up with the “characteristic “ spiel and stop the Stage 2 fix in that bulletin as we thought.

I was just trying to fill @waspmike in with the history re his post above

The message was first mentioned and discussed here > VIBRATION ISSUE - hot off the press!

They might be right as we know of at least one occasion that it hasn't worked so they wouldn't waste all that money on a fix that won't 100% work, so rather than spend money they just put the line out that it's a characteristic!

It's been said before, nobody knows the long term implications of that vibration, has it really been fixed or hidden on the cars that don't have it!
And the cars that it's getting better on as they do more miles, could it mean there is some premature wearing of a component happening that may be causing it to lessen!

A lot of unknowns with this all made worse by MGs stance

There’s some videos on the Facebook group showing the driveshaft out of balance as it rotates, and also some sort of frequency graphs of the vibration at the 68mph speed . Too technical for me though!!

I wonder how @Freeagain and @Bricktop X PWR are getting on with their group litigation case ? I guess it may be going to court as everything’s gone very quiet.

The driveshaft imbalance sounds the likely issue as when you look that up it states it causes vibration especially at higher speeds.
Also states it can cause premature wearing of the joints.

Saw on an Australian X Power site that an owner had the bushes on the car replaced as he has suffered from the vibration
