A rather worrying announcement on the MSCC website about a problem with Plus Four and Plus Six cars advising that owners stop driving them until they are checked and rectified.

See link.CX issue.

But still nothing on the MMC website

There is an ongoing thread about this in the CX forum: Safety Recall - Brakes

Yes I know. We centre secs we asked to share the email on that post which I have done but it is odd MMC don't have anything on their website.

One member off AngleMog has confimed this is real. A sad day for MMC & CX owners

Not a hoax and has been confirmed to me via the factory and MSCC Chair, all of FolkMog CX owners notified, hopefully owners get their cars fixed asap and do not miss out on holidays and events.

Dealers are contacting buyers. This should cover all cars but any sold on would be more difficult to trace. DVLA can usually be used as they would have new keeper details. Probably only a very small number of such owners.
With upcoming big events and summer trips it is not good news for owners.
I wonder if the dealers dropped by MMC might be tempted back to help remedial work. It would certainly help speed up the process.
Recalls are not unknown for any manufacturer. Usually due to parts supplier problems.
I remember when in the steel industry we had to recall a batch of steel for Ford Escort drive shafts. Routine checks discovered mild steel instead of the correct grade. Luckily the stocks at Ford hadn’t been used so no cars built with it. We discovered the problem and alerted Ford. All suspect stock returned. We tested it all and removed any wrong grade parts.
It did result in a visit from Ford QA and increased checks for a while.

Good luck with contacting them. I'm still waiting for my licence back after 5 months!!

Bob try phoning them, I did and got it back 3 days later. I did a change of address on line and something wasn't quite right they just shelved it !!! The guy on the phone fixed straight away.

I have phoned them several times and got the "We are very busy" message and then disconnection. Can I ask when you did this? Fairly recently? Cheers.
