OMG Calum what mess.
Am so very sorry for you and hope that MMC put things right pronto for you.
It does make you think that these chassis issues are still not resolved - even with the latest fix??
Am not an engineer so do not know.
BUT hope that all owners rigorously check their cars - and do so very regularly.

Calum, that is awful and casts further doubt over the engineering skills at MMC.
Thank goodness you had a safe journey back from TOTH.
Hope MMC sort it soon.
All the best from us both

I didn't know that the chassis on 2013 cars with the small triangular plates were subject to failure.
I haven't received a letter from Morgan yet.

I haven't received the letter yet either, just have the pdf that Mark posted on here last week. It does state that cars up to the end of 2013 are affected. Thanks to all for the good wishes and expressions of horror. There will be discussions behind the scenes over this but the nature of it is that these can't really start till Mark Evans gets back from holiday. I hope he is having a good break so to speak.  What is probably most surprising about this is how little effect it has on the handling on the road! Presumably the main loading on the tube is compression at the break so it mainly holds together even once mainly or completely severed.

The guy in this video seems to do a good job of explaining why triangulation of a chassis is needed. https://www.youtube.com/watch?v=52VVaKeYuyw

Sorry to see that Calum , hope it's sorted soon .
I recieved my letter today with the ridiculous sentence in the first paragraph "During normal operating there have not been any recorded instances " . We all know this to be a lie .
My chassis was replaced last year with what appears to be a 2014 spec one , including new uprights . I rang the factory today asking if mine still needed to be inspected , Russell Cartwright was out but I spoke to Mark Cerrone who confirmed these chassis do not need to be inspected .
Going back to how a break effects the handling . My car was pulling to the left but otherwise felt ok , it had bent as well as cracked .

As bad as a chassis break may be, I think a replacement chassis with the welded in triangulation will be the better option in the long run, than the additional bolt in bracing, that would need a regular spanner check.

My June 2013 build car had to go back to the dealer in Perth for other work but I had already asked them about the mod. I did not receive a letter but the dealer has the kit (bolt in I assume) & it should be fitted by now.

It will be interesting to see what happens with the "Australian" version in relation to chassis and other 3W issues. I'm looking forward to seeing one very soon.  It’s frightening to see that. The reasons are quite obvious for anyone with mechanical background. It’s called mechanical fatigue of the tubes at a flexing point in the frame. Any good engineer is able to master the frame with sophisticated computer programs. Every time you hit a pot hole or a bump the frame flexes at that point and in the end collapses. When you add triangulation to these tubes they stop to flex. That’s what should have been done from the beginning.
As it is difficult to run a lot between the numerous breakdowns, there were too few vehicles with high mileages to have a good return of the problem.
I’m still waiting for my letter from Mark Evans and also for a reply to my letter sent to him on 5th of January.

Callum, so sorry to hear that you're stuck on 4 wheels for the next month or so, but relieved that you're in one piece! Do we feel confident that the bolt-in or welded-in A frame is a permanent solution or is it just moving the stress point? i.e. Will there be a topic on TM at some point about cracking just in front of where the A-frame meets the front tubes?
