MG4 Undertray Poll

[AndyL61]

If this is a characteristic, then each car has it's own character. They're all different!

 

[AdamskiEM]

That's a Bactrian bulge , some have a Dromadary bulge .

Guess I got a good deal. 2 for the price of one.. ??

 

[PeteC]

Mine as it arrived on the delivery transporter.

 

[tsedge]

I must say chaps, I admire your bulges...! (I'll get my coat). ?

We could start a new thread. Rate my bulge.

 

[colsky]

So the votes are now 21 with the bulge and 2 without.

The bulge pictures don't appear to be uniform, so it can't be "by design".

But, if the voting can be said to be representative, then 21 to 2 presumably means that the bulge can be said to be mostly "normal".

Apart from obviously looking odd (if you just happen to be underneath the car!) and a possible (unproven?) slight drain on the range, can we now say that the bulge just is what it is, and not a real problem?

No. There are two types of bulge - the droop at the front which requires rectification as it is likely to eventually fail when it drags in standing water, and the "not flat" parts which are unsightly but unlikely to fail.

Mine probably falls into the latter description.

I still say no it's not normal. Normal in my opinion is panel's that should fit neatly together with no discernible gaps. Not waterproof but protective. Depending on the gap who knows what object/amount of water can be forcibly inserted into the components above.

My droop is quite large, and like the largest that people have put pictures on here of. So in the first category. But my dealer said that its "normal", its on all the MG4s that they've seen, the nuts and bolts are all sufficiently tight so there's no danger of it moving, and everything above the undertray is sufficiently secure and insulated anyway. So if their last 2 comments are accurate, why would an undertray "eventually fail"?

I was out on a drive on Sunday, when it had been hammering it down all day, and had no choice a couple of times but to drive slowly through some serious puddles. So I'm hoping their comments about the undertray were correct.

Colsky, did you not see one comment on this forum where an undertray was ripped of by the force of water catching it. If you drive enough times through volumes of water/snow the forces will stress the plastic and eventually cause it to crack at the weak points, I.e. around the holes. Maybe not today, or tomorrow but....just my opinion about why it should be flat

P.s perhaps even wind drag will have a long term effect

I agree and that logic makes sense. I suppose I'm just trying to convince myself that its not an issue I need to worry about.

Snow will be the killer and MG will have to resolve when hundreds of cars go to dealers with a ripped plastic undertray in their boot!!

That’s a very good point. Snow would rip that thing clean off wouldn’t it. ?

 

[Deleted member 9909]

Hence the reason I mentioned it...easy to forget what may hit us and the undertray shortly?❄

 

[Les burrows]

This is poll will be a good one in the respect of having some thing to show the dealers who are saying they know nothing about this issue.

Last week Tuesday I think it was my dealer told me they have been told by MG this problem was being investigated.

My wife’s car came with it pre installed at collection and I pointed it out to the sales staff who did make a note about it for us I had a very quick peak under 3 other cars the same day all 3 had it but to a different degrees on each of them.
So as requested here is a picture of our 4 SE SR which I have posted before I took this when we got the car the green ring is my torch light.

I'd be tempted to put a strip of duct tape over the gap.

I reckon that wouldn't last five minutes to be honest

But it could make some interesting changes to the noise it makes.

 

[Deleted member 9909]

Perhaps a new feature...MG4 duct tape streamer ? with associated gap whistle ????
