MG4 X Power Vibe/Hum 65 to 75mph

Got about 8000 miles on mine now and it’s changed quite a lot. It is barely noticeable at 70+ mph now but starts doing it at 50 and is at its worst at about 55, especially on the sound front, though much more mild than it was around 70 mph when it was brand new.

I’m wondering if anyone has tried to getting this fixed independently beyond wheel balancing and changing tyres?

Unfortunately I’ve had to endure more after sales uselessness from MG and in this instance I know what’s wrong which demonstrates how crap they are.

I’ve got the squeaky brakes problem which others have had and is really bad in reverse. They had it twice in the same day and didn’t fix it and it’s booked in again, from the next day (and I doubt they will fix it this time). Predictably they blamed regen and condescendingly explained “you had it set to level 3 but there is a setting on the screen we have changed it to level 1. We cleaned the brakes and is okay now” 🤣🤬

I asked my brother whom has been a mechanic for over 30 years and is also an MOT tester about it and he said “The rear discs are scored and near side pads aren’t contacting the disc properly, no wonder they are squalling. It needs new discs and pads. If that was in for an MOT I would give it an advisory. A strip down might fix it but probably not and they must know that. Tell them you want them replaced.”

Of course they haven’t even tried to strip them down, they just took it out and slammed on the brakes a few times like I have, which makes it go away for a few hours and then it comes back… WHICH IS WHY I TOOK IT IN UNDER WARRANTY!!!’

Obviously there is more chance angels will fly out of my bottom then MG will actually replace the discs and pads, yet they are relatively cheap components. It’s got me thinking, perhaps the vibration is fixable without reengineering the car…?

For example has anyone tried to have the driveshafts balanced or got them tested for balance and order a replacement?
 
So basically, the same old, claptrap. 🙄🤪
It’s so frustrating! They are trying to blame me for the noisy brakes because I’m using too much regen even though the car defaults to level 3 and I don’t leave it on that anyway.

The second time on the same day with the same problem they handed me it back, they offered to show me how to change the settings ***! How about fixing the f**king thing!!? WLTP figures are based on regen being on, not that it makes any difference if I turn regen to minimum!

I really like the car, I’m just really disappointed with some aspects. Unlike some people I’m not hell bent against MG even though I probably should be! I’ve recommended the MG4 SE to a friend but she wants me to check it over too.
