MG5 Blistering .

[RobbieC]

I purchased a 2021 Mg5 long range Exclusive from Arnold Clark, 5 weeks ago. Yesterday I discovered blistering on the rear wheel arches which wasn't there when I bought the car.
Has anyone experienced similar problems, and what are my options ?
Thanks

There seem to be depressions there as well, some (amateur) accident damage repair?

I would speak to the dealer about it. If it was accident damage it need not have been serious, a car park scrape for example.

That's what I thought at first, but on closer inspection, the depressions appear to be water.

Here are a couple of previous MG5 rust threads.

Thread 'Is rust a problem on early MG5s?'

Hi folks,

Maybe you can help me. I am often being told that "modern MGs rust", that they are not well protected and that after 4 years or so there are problems.

Is this true at all with MG5s? There must be a number of you with older 5s now who can comment.

I'd like to gather some evidence to repudiate this if it isn't true.

Thanks in advance for your comments.

Thread 'Rust on rear drivers side arch'

Aug 7, 2025

So, it appears the rust has started on my 2021 MG5. I wash it at least once a month so it's appeared within the last 30 days as the last time I washed it I also waxed the whole car so would of seen it then. No direct chip where the two bubbles have appeared, the paint has separated from the body where the bubble is.

It's in for service on the 18th so will mention it then, but no doubt they'll blame it on some stonechip or another

Do you have any pics from when you bought the car?

There may be pictures on the advert of the car if that's still on line?
