Undertray broken off

[goldie]

Hi All, First message on this forum! I’ve had my MG4 long range for around 6 weeks and done just over 1k miles. Last night I noticed that something seemed to be dangling down from the underside of the car. I was shocked to find, when examining it closer today, that it appears that a large section of the plastic undertray at the rear has fallen/been ripped off (see images) I can’t honestly say when this happened.

After coming on here and finding that there are many examples of badly fitting/bulging fittings, and that in at least 1 case the tray came off when going through water, I suspect it happened when driving in the wet and going through big puddles but actually cannot put my finger on exactly when. There does look like a particularly large bulge on the remaining part of the undertray though.

I have spoken to nearest dealer but cannot get them to look at it for 4 weeks. It is mine under the NHS lease scheme but they just said I needed to sort this with a dealer. It looks like the part remaining is secure but I am wondering about the safety of driving the vehicle in the meantime. Any thoughts/help/suggestions here would be truly welcome. Thank you.

The thing dangling down it a bit of black fabric btw and it doesn’t easily pull off. I can’t tell whether it has just been picked up and snagged on the sharp edge of the broken plastic, or whether it actually originates from sitting above the tray, within the car. Thanks

Don't worry it's by design according to MG

 

[goldie]

I’m really not that happy with MG dealers response so far tbf.

I deleted a few posts concerning a misunderstanding that was cleared up, so we can keep the focus of this thread on this bloody undertray having caused yet another issue.

Recently replaced my undertray. The thin and brittle plastic 'only' fractured across one of the corner brackets, but didn't want to risk it ripping off during use.
Took many weeks to organise (and a few repeat visits to the dealer when it hadn't been ordered as previously promised, etc.) and ended up costing more than quoted too, but they did at least fit it for free.

In case of use to anyone, below are the part numbers from the invoice, and the cost (excluding VAT and any labour):

As I didn’t get a very good initial response from the MG dealership, and worryingly his main excuse was that they are inundated with ‘problems similar to yours’ I got in touch with the leasing company who have it booked in to an approved (but non MG) garage next week. Surely all they can do is remove the remains of the tray and check for other damage though? Assuming they would then need to order the replacement tray from MG and rebook to fit it. Is it safe to drive in the meantime if there are wet conditions? Will this count as ‘warranty work?’ I don’t know, but I guess as they technically own the car it’s their decision. The worrying thing from checking out other threads though is that there is no guarantee that this problem will not repeat. All very frustrating from my new ‘all in, no issues, cheap yet trouble free motoring’ decision.

That’s great, well the fact you got it sorted and that the cost was not to much anyway, shame they messed you about, but good info, thanks so much Nick.

I lost the undertray on my Peugeot 306 when it was middle-aged. (Or rather, the rear fixings became detached, causing it to drag on the road.) Two separate garages told me to take it off and forget about it. I think its main function was aerodynamic.

 

[goldie]

I hope you’re right Rolfe, just thinking that maybe on an EV there are more electrical connections etc that may be prone to malfunction if they got wet. Also not great for efficiency if aerodynamics compromised. However my immediate concern is safety, getting it fixed and also deciding if I have made the wrong decision with this car, and what I can do about it. It’s such a shame though as she is a dream to drive!

Whereas on the MG4 the bulge makes it anything but.

Language moderator please!

If the forum doesn't block/mask it then it's an acceptable word.

 

[Rolfe]

Yup. Type exactly what you want to say, openly and without shame, and if it's not allowed the autocensor will mask it. Incompletely masking a banned word is what gets you in trouble.

Incompletely masking a non-banned word is just weird.

 

[Ian Key]

That's w1erd

I would not of minded paying for the undertray, but surly the original bolts and accessories were re-usable?

 

[NickL]

I may be wrong but think I saw a post about this problem from Austraila, where there is now a bracket of some form being fitted to strengthen the tray. There were pictures. Anyone know about this.

No worries, I just wish they’d take it more seriously and not just rely on the “get it done at your two year service” response. Agreed personally I think it should be a mandatory update dealers have to do and covered free by warranty

Thank you. We really should be getting this in the UK.

I've already told my dealer about this bulletin (I'd noted the issue on collection), and that I want this fix when it becomes available in the UK.
