MG4 X Power Vibe/Hum 65 to 75mph

[Bricktop X PWR]

I'll put something together, might take a while. The printed correspondence is 53 pages long. There's least another 30 emails I've not bothered to print copies of.

I rejected it via the leasing company, and they coughed up. MGUK were not particularly helpful, "characteristic of the vehicle" garbage. In the end the car was collected by British Car Auctions. I suspect it did not go back to MGUK for fixing.

There you go, straight into the auction for some poor unsuspecting punter to purchase further down the line!

Yep, unfortunate for the next owner. But that's the way it goes. Result for WW though. Just a shame, it had to come to that in the first place. ?

Luckily the new punter still has consumer law to fall back on regardless of who they buy it from.

Unless ultimately its a private to private sale, then it's caveat emptor!!!

I know, I felt bad about it but what could I do. I told the driver who the collected the car and he texted me to say it vibrated.

Well done on getting it rejected ?

Would you mind putting together a very brief summary of the processs you went through to succeed in rejection as somewhere along the line MG UK must have accepted it was not "fit for purpose " or "not of a satisfactory quality".. Maybe post it in here :-

X Power Rejection.

My PCP runs out next September ... I doubt it will be setted by then. I can see this lasting years myself if it goes through the courts. My VW dieselgate claim should have been cut and dry but that has been going on for three or four years now !! I think you'll find this is a different...

Many thanks ... I'm sure your case would help us all as it sets a precedent IMHO.

Done

From Facebook's "MG4 X-Power Vibration Complaints" group :-

Apparently the official MG UK spiel is as follows as of 24 September 2024 :-

"MG Motor UK is aware of reports from some customers regarding a vibration experienced in certain units of the MG4 XPower model, particularly at speeds above approximately 55mph.
After thorough inspections and assessments of multiple vehicles, it has been concluded that this vibration is a result of road feedback being transmitted through the vehicle’s steering system at higher speeds. This feedback is a characteristic of the MG4 XPower model, largely due to the additional drive motor and the modified suspension and steering geometry unique to this variant.
It is important to emphasise that this vibration does not indicate any safety concern or compromise the mechanical drivability of the vehicle. As such, there is no repair required for this issue. The vehicle continues to perform within its expected operational parameters, and the vibration should be viewed as an inherent characteristic rather than a defect or fault.
However, MG Motor UK recognises that some customers may find this vibration disruptive or annoying, even though it does not impact the vehicle's safety or performance. We always place the highest value on our customers' driving enjoyment and comfort. In response to these concerns, we have explored potential options to help reduce the sensation of vibration that some drivers feel through the steering wheel.
After extensive testing, the most viable solution identified was the installation of a steering wheel damper. This damper has been designed to reduce the amount of road feedback transferred to the driver, thus minimising the perception of vibration. While the damper has been proven effective in many cases, it is important to note that its success may vary slightly from vehicle to vehicle, depending on component production tolerances. Nonetheless, it remains a valuable option for customers seeking to reduce the vibration they experience.
MG dealerships are welcome to fit the steering wheel damper for any customer who wishes to explore this option, provided the vibration characteristic is confirmed during a road test by an MG technician. This allows for a tailored approach, ensuring that the solution is only applied where necessary and beneficial.
We are also aware that an internal MG communication, which referenced a development proposition involving suspension part replacements as a potential solution for the vibration, has been shared publicly. This communication was issued internally back in April and has since been tested. Unfortunately, it was found that this proposed solution was ineffective in reducing the vibration on UK models. As such, it is not being pursued further as a resolution for this characteristic.
MG Motor UK remains committed to providing the best possible driving experience for our customers. While no repair is necessary for the vibration, we will continue to offer the steering damper as an option for customers who feel it may improve their experience. We thank you for your understanding and cooperation as we work to maintain the highest standards of customer satisfaction.”

So after all that Waffle, and god knows how many, complaints, they are STILL saying there is absolutely, NOWT wrong with the X Power. They've tried this damper thingy, not because they are admitting anything, but just to appease the owners, and hopefully you'll go away.
What a bloody sad state of affairs. ?

 

[Bricktop X PWR]

What a complete load of ass covering BULLSHIT.

How bloody dare they!

Road Feedback??

MY LEFT AND RIGHT TESTICLES!!!!

If road feedback was the cause, then you would have exactly the same experience, doing the same speed, every time you drove on that piece of road.

That simply is not the case with my car.

Some days it will be worse than others.
Some days it will start earlier, go on longer.
Some days you are convinced they are gone, before they reconvine on the return journey.

I have a piece of the A40 that goes from St Clears to Carmarthen (and back) which I use 3 times a week, every week, and have done for the last 5 years.

None of my other vehicles have done what the X Power has done from new.
None of them!

To say this is a "Characteristic" is outrageous.

Why does my friends X Power @DougC not have this Characteristic??

What makes him so bloody special MG?

What about the other owners who don't have it either???

Explain that away for me if you would be so kind!

Oh and the vehicles owned since I moved here since 2019?

A 2008 Mini Cooper S. No Vibes.
A 2017 Mini Countryman. No Vibes.
A 2020 Toyota CHR. No Vibes.
A 2017 Range Rover. No Vibes.
A 2020 Mercedes GLC. No Vibes.
A 2021 BMW 330e. No vibes.
A 2019 Tesla Model 3. No Vibes.
A 2021 Audi Etron. No Vibes

A 2023 MG4 X Power. Vibes Vibes Vibes Vibes Vibes.

You quote "This feedback is a characteristic of the MG4 XPower model, largely due to the additional drive motor, the modified suspension and steering geometry unique to this variant"

Funny that.

Audi seemed to have managed to engineer a vehicle with the extra motor, modified suspension and I'm sure, unique geometry without issue.

And funnily enough, so did you in later production of the X Power.

Your statement would only stand up if ALL X Powers displayed this characteristic, which of course they don't, so.......

See you in court.

P.S.

I've just re read your baloney up above and on reflection it really is gut wrenchingly embarrassing.

 

[OriginalBigAl]

In one sentence it's a vibration, in another it's a perception, i.e. "it's in your heads". This problem is worldwide and should be addressed by SAIC as a common fault or design failure. By subdividing it into regional areas they are deflecting attention away from themselves and leaving the subservient area controllers to manage/deflect the issue.
This issue affects both LHD and RHD X powers in differing degrees, perhaps a multi-country legal challenge bypassing the middle men could be organised by the legal teams representing some of this forums members, or at least looked into.
For my own part, and other non X power owners we look on in interest and sympathy, but it does show how we would be treated should a similar common problem should develop on our vehicles.

 

[tsedge]

Unlike the previous document, this message does imply that they won't be pursuing a better fix.

My guess is they've concluded that a design change was needed to fix it (which presumably more recent cars have) and it isn't practical to retrofit.

This isn't good enough.

At a bare minimum they should offer:

• Existing customers with the problem the opportunity to swap their vehicles to a more recent model without the issue, with minimal and fair costs to "upgrade".
• Rapid and simple uncontested rejection/refund for existing customers with minimal fair deduction of mileage/usage.
• Compensation for affected drivers as a third way to settle the issue.

There is still the possibility of an after-market fix being made by someone and becoming generally available.

Good luck with the court cases.

 

[WibbleWobble]

That's the same horse odure they fed to my leasing company. I can't see them getting away with it in court. It's complete garbage. What they are really saying is that it's going to be too expensive for us to fix.

I suspect that once the "stage 2" fix was leaked and their Chinese masters looked at the potential costs from the numbers of cars involved they swiftly pulled the plug on it.

What a load of crap, basically saying their cars are chucked together and depending on how arsed we were on the day we built yours it could be better or worse and make a difference or not!!

Bloody big production tolerances that

 

[tsedge]

If it is indeed a resonant vibration as has been reported, then it will vary from car to car and mitigating it (as opposed to designing it out) will be more of an art than a science. So this is plausible.

 

[Chrisdriving]

Surely by trying to prove later cars do not have the problem would be evidence enough that MG changed something more substantial .
If no mods done then later built cars would also suffer.
New build car vs old build car both up on ramps and compare components in the suspect areas.

It is almost certain design changes were made in the factory to eliminate the problem, but these are clearly either not possible to retrofit or prohibitively expensive.

Considering the damper made mine considerably worse ... RIDICULOUSLY huge production tolerances!

 

[OriginalBigAl]

When I was six I went to the circus, and Coco the clowns car had a" characteristic" whereby if he slammed one door the other would open , after two attempts both would fall off. Not desirable for a road car, but for deliberately engineered and tested comic car, funny.
If that excuse is the best they have you should be on a winner, unless of course it was deliberately made that way to give it an unique character , which after much testing was signed off by senior personell as perfect, and then advertised as a feature that no other manufacturer could match.

 

[LenEV2016]

We are dealing with a company that passed off an under tray that was quite clearly to flimsy for the job and quite clearly had the fixing holes out with MG's "competent tolerances" fitted anyway and passed of as a characteristic of the car.

I'm surprised they didn't come up with some nonsense about the oil leak going back to MG's British roots and being a homage to 007 and it was actually part of the cars in built defence system against tail gaiters

 

[Daedalusminos]

I googled the part numbers in the tech note. The subframe returned a match....but I think there were two numbers so possibly an alternative solution, I didn't find a match for the mounts.

 

[Bricktop X PWR]

As you have said, it's not a huge issue for me either, but I am looking forward to your updates m8 ?

Just as an aside, I have noticed that when I am on my friends private test track, powering up from a standstill through to 90-100mph I didn't notice any vibes at all.
I wonder if that because all the components are under load, negating any chance of any resonance.
Anyone else noticed this?

Going back through all the 'Ye Olde' posts and saw that I called you 'm8' Sue. @Freeagain21

Can I just apologise for that.

I didn't realise you were a Bird!

It's a bloody good point pal.

I mean at the start they could not put the correct amount of oil in the gearbox.

Also seemingly unable to manufacture an undertray to fit properly.
A bloody undertray MG!

What hope did we have when they upped the ante with an extra motor and all the twirly bits??

Not bloody much it would seem.
