Cracks in rear light plastic - internal

[Alex1985]

Yes, mine is cracking, small thin cracks that we used to call crazing. The dealer said it was accident damage which I refused to accept. He photographed it said that he we submit it to MG. I wait for an answer.

Mine's a 23 plate - sent images to the dealer today and see what they say.
It's definitely stress cracking and looks like it's propagating from the bond of the inner and outer sections to me.

I have the 2025 mg hs. I have these cracks. Slowly getting worse. Noticed in week 1 of brand new car. Looks to be over stressed and temperature change. Dealership submitted warranty claim. Yet to hear.

Got an answer back from the dealers it went up to MG and they've agreed to a warranty repair replacement as of last Tuesday.
Annoyingly a bloody Tesco's van rear ended the car on the previous Saturday and despite a very broken bumper, boot and light bar it hasn't touched the light clusters.
MG still happy to replace them once I get it back.

It's been a month now and still not a peep about warranty on the light. Will contact them shortly

As a matter of interest, do you guys with these cracks park with the rear of the car in the sun ?
I ask because the rear of mine is in the shade all day and I have no problems with cracks and only had a bit of the condensation in the lights problem when I perked with it in the sun for a couple of days. I'm thinking the heat and expansion may be something to do with the cracks.

I park outside my house and the rear light cluster is mostly in shade at all times.

Hi folks,

I was just about to plug my car in ready for a journey tomorrow, and I noticed two parts of the left rear brake plastic were damaged. The damage itself almost looks like a stone has come up and hit the light cluster but upon inspection the damage is internal and not external. See the picture attached, will be contacting the dealer to discuss options.

Has anyone with similar had repairs done under warranty or should I brace for monetary impact?

Reported a similar occurrence previously in mine: MG4 Lights cracked in heat In my case the part was changed under warranty.

That's reassuring. It's been a month and still no contact from the dealership
