MG4 X Power Vibe/Hum 65 to 75mph

[OriginalBigAl]

Does anyone know a four wheel drive specialist with a suitable rolling road test bed, by isolating the front wheels from the rears which could be steadily taken up to speed, would it be possible to ascertain if the vibes come from the back end if they are spinning and the fronts are stationary. No vibes would suggest the original thoughts were correct and its a front end issue. Hopefully the costs would be recoverable through the legal action and it would give more evidence to that procedure.

It's a rear end issue pal.

The front motor and associated gubbins was an obvious candidate for the issue.

A couple of weeks ago I ran 37psi in the rear and my vibes were back to their worst.

The suspension relocation "Fix" Read "Not Fix" was for the rear of the car.

Thank you for your further correspondence and I do understand that this does not meet with your expectations.

The problem comes from the car being a high powered vehicle. I know that I have said that before, but if you compare to a high powered petrol vehicle for example, they would shake and vibrate when power was demanded. Although an electric vehicle isn’t exactly the same, the effect here is of the same consequence.

We are trying to look at ways to improve driving experience, but it is unlikely that it can be removed completely.

Absolute disgrace, it's insulting to think they believe that customers will believe this absolute crap.

True, not really thinking it through, although since they are not implementing that fix it seems they don't have much confidence in it themselves. Unless of course that newer design is already in some form incorporated into the later models as factory standard ?

I personally think it's down to cost

Agreed. Your not telling me that a company with the resources of SAIC. Can't fix the vibe problem. They simply don't want to, because as said it's to expensive to retro-fit. So they've come up with half arsed fixes and total bullshit. To try and fob you off. Hoping you'll eventually just give up and fade away.

And sending out pre prepared scripts for folk to stand and read and pretend that it's not an issue.

MG UK need to sort it out and stop hanging dealers out to dry.

Although some of them couldn't give two ***** either

So it gets better. I replied to the e-mail I received politely, explaining that the vibration that was not present when there when 'high power was demanded' but at a steady state when in the 65 to 75mph window and that I had owned several high powered petrol engine cars, none of which had a vibration issue like this. I was also honest and said that I felt somewhat insulted by some of the content of the e-mail and I also asked why later manufactured cars no-longer had this 'characteristic' .
This is the reply I received today:-

Thank you and yes, we know that, it is how the car has been set up. I also hope that you appreciate my honest and open replies even if you don’t fully agree.

I have never driven a high powered car (Petrol, Diesel or otherwise), that would not vibrate and become loud when power is demanded. As stated, the principal here is much the same. I have worked for a number of motor manufacturers and driven a lot of cars over the past 35 years. This isn’t a competition, but I wanted to assure you of my background.

Engineering (UK engineering) have explained to me why this occurs, but being engineers, it is far too in depth for me to try and explain. They are looking at solutions, but in all honesty, they have experienced it and don’t see this as a great problem to resolve.

We aren’t ignoring any customer here, but expectations do need to be set as the car is operating normally and correctly. If a better set up or component is found, then it will be offered to the network.

I will reiterate that up until now, this is one of our flag ship cars. We are not going to be happy with it if customers are not happy with it, but this doesn’t mean that we will be able to fully meet with everyone’s expectations. At some point, we may have to state that there is nothing more we can do.

So there we have it folks. All high powered cars vibrate in this fashion - we are all wrong. The reason for the vibration is far too difficult for us mere mortals to understand (I did take the bait on this one though and asked whether he could elaborate as I felt that my degree in mechanical engineering design & 30+ years experience may qualify me to at least try to understand it!).

My favourite part of the email though is this quote " [the engineering department] have experienced it and don't see it as great problem to resolve"

I am almost speechless with the contradictions in the e-mail, stating they are not happy if customers aren't happy on one hand but then stating it isn't a problem worth fixing & that it is normal and correct.

Unless you go on a good test drive, like say an hour, with a good 20 mins of that on the motorway. You might not even notice the vibe, even if it's got it. You won't notice it, just going around the block or even a good hour on normal roads.
Only a Good long test drive will do.
Trouble is you can't have good long test drive, if it's an ordered one.
Unless, as mentioned, elsewhere, you get it in writing, that you can reject it, immediately, if it's got the dreaded Vibe.
So it's, Catch 22. Pot Luck. Prayer mat.
Obviously shouldn't be like that.

Or just don't buy an X Power, put your money into a more reliable brand and a manufacturer that you can trust. Best way for MG to sit up and take notice is if people stop purchasing as it cannot be guaranteed.

But then in the future if you do buy, with the merry go round and the denial of the dealers and MG, the releasing of the technical document of the fix, then the denial of this document, then the statement that it doesn't fix it...but someone at SAIC must have wasted their time producing said document. To the guys that are now pursuing a court case of rejecting thier cars because MG UK are not listening and treating thier customers like idiots....if you have a problem with your new MG in the future...would you worry this would happen again and MG denies any issue.

I wouldn't trust this brand ever again.

I'm too furious to reply!

Oh, wait a minute....

Cheeky Bastards.
Honestly.

Un Bloody Believable.

When I get a similar reply (I'm sure) I'm going to ask why later cars do not have the characteristic?

WHY
WHY
WHY
WHY
WHY???

Answer Me Gary! WHY?

Nobody is arguing that a High Performance Petrol Powered car becomes loud when performance is demanded!!!

My VXR8 with a straight through exhaust was one of the loudest cars in Christendom, but managed to travel between 65 and 75 mph without bloody vibrating.
(And that was built in Australia!!!!)
((Don't take the bait boys!! Beautifully built and NEVER WENT WRONG, NOT EVEN ONCE IN THE TWO YEARS I OWNED IT GARY!!))

I mean what fudgeing planet is the man on?

Planet F-IN GORMLESS is what.

Spot on, unfortunately they will still sell them, where else can you get a brand new car with that performance for under £30k.

People will buy them that have never had a car with that performance before and not knowing any better believe the bull MG and the dealers are peddling.

Interesting to see if it's mentioned on the live stream tonight

 

[seamust1000]

If we believe Gary...all MG X Powers would have this issue...but they don't, new models have been fixed.
And if it was a characteristic, it should be in the sales material to let you know before you buy...so they are breaking the Trades Description Act as the car was falsely marketed.

Agree with, almost everything you've just said. Except if you've really set your heart on an X Power. You can definitely take steps to make sure you get a good un.
The main one being you get a good long, test drive. At the very least an hour, but must include extended motorway driving. And obviously check the car thoroughly. And hope you get a good dealer, there are some out there. Yes of course there are probably better cars out there. But for a LOT more money. Bang for Buck they can't be beaten. Get a good, X Power and they are Fantastic!

Mine would have been lowered and on 20s months ago if I didn't have the vibes.
This was easily a 3 year car for me If not longer.
As you say m8 bang for buck?
Unbeatable.

You just need a bloody good one.

Could it be that the "fix" on new cars is a tweak to the chassis that would be very expensive for MG to retrofit on the cars with the vibration. Might explain the deny and obfuscate approach they are taking (somewhat similar to the clerical abuse scandals, wait long enough and it will go away [they hope]).

 

[Smudger558]

I'm glad I only leased my xpower for 2 years. My car has vibration over 65 mph it's only slight but still annoying all you lot who bought your xpower I really feel for you. Mg uk are absolute tossers. Anybody thought about letting watchdog on bbc know
