I have a Trophy just over a year old. It has never been through a car wash, or had any sort of bump. Today I noticed what looks like a crack in the plastic on the rear boot light assembly. It is just over an inch long. I am at a loss to understand how it could have happened.

Has anyone else had similar?

Do you ever pull the boot down and close it using the boot lip?

 

[NickL]

From fully open, no. I am not tall enough. The last bit possibly, not sure. The crack is on the left hand side, and I am right handed, so I doubt this is connected.
Thanks for the idea though.

See also MG4 Lights cracked in heat on cracked or crazed tail lights. That thread mentioned that others were finding cracked light assemblies, though I didn't find any with a quick search. I'm happy to merge threads if this is actually a common issue.

@Coulomb several posts relating to cracks...

Interesting scratches inside the rear spoiler

Just noticed these on the rear spoiler of my Trophy. Although they look like scratches, they are internal, with just a smooth surface on the outside, so potentially internal cracks on the acrylic? Anyone else had similar? UK based, no recent exceptional cold weather experienced, and...

MG4 Lights cracked in heat

Hey all, Has anyone else experienced this issue? I noticed today some cracks in my back light on the tailbar but I can't feel them, so they're definitely internal. I'll have to contact the dealer about this as it's not even got that hot in the UK yet! Has anyone else had this? MG4 Trophy...

Ok, thanks. These don't seem to me (so far) to be candidates for merging, as there are several core topics (condensation, cracks, crazing, etc) so I've just added some links at the front of each thread to the others. It was a lot more work than I thought, so next time may be a merge after all.

After usual hand car wash noticed still wet in places when I walked around car. Found cracks on top part. Happened in May, no reason for this to have happened. Will find out what garage says later this month.

Mine cracked internally, replacement sent from China to the dealer who is installing on the 18th... but noticed that rear quarter lights are starting to do same. Mentioned to dealer.
Meant to say, replaced under warranty.

Not easy to see in your picture, but if you are referring to the long line, the other side will be the same. Mine has it on both sides in exactly the same places and they are the joins between the sections.

Mine was also replaced under warranty.

Mine has some internal cracking which appeared after a few months. I will get it fixed under warranty when I have the first year's service.

 

[NickL]

Start the process early. The dealer will need to get MG to agree, then the part has to be sourced.

 

[AndrewBes]

Many thanks for the tip.

Ye, definitely joints or moulding marks. I nearly had a heart attack when I first noticed this on my two-day old Trophy ER but checked out another MG4 in a car park and realised these lines are meant to be there!

Give my regards to Rutland, used to live in Market Overton and should never have left!

Garage tells me it "wont "get replaced under warranty.

That was the first response I had, but my dealer is small family garage and they tried asking MG, not expecting it to be agreed. After some tests to prove the crack was not on the outside, it was agreed by MG to swap it. I had to video me pulling a finger nail over the crack. I pressed hard enough to scratch the plastic, but it proved the point.

 

[AndrewBes]

I have got similar cracking on my MG4 Trophy and am waiting for a response from MG. It appeared within 2 months of me buying the car new.

My rear driver's side light lense is cracking too inside, going in for a replacement on the 3rd Jan
