MG5
Had my MG5 PFL SR from new in June 2021, performed faultlessly and a joy to drive. Until June 19th 2025..... a flurry of faults (Autohold fail, Hill Hold unavailable, System Fault) were displayed and it failed to start. Had to wait a while to have it towed to the local MG dealership in Warrington. Now over 5 weeks later it's still there - the speed sensors were replaced, and now another flurry of faults has been displayed to do with the main drive. At least they gave me a courtesy car after a few weeks. Wondering if I'll ever get my MG5 back. I suppose this is what happens when you mix cars with software, a Devil's brew. Has anyone experienced similar? It will be 6 weeks on Thursday and no nearer to my car being back off the slab!!

It sounds like the 12 volt battery went flat from the symptoms you described. Surely it can't be that ?

No, was all fine - had just been driving earlier that day. I did undo it and reconnected, same result. Also have one of these chargers that I carry round, made no difference.

Sorry to hear of your problems :(
Is the courtesy car something decent?

Since Holdcroft is a Honda dealership as well, they gave me a Honda Jazz - it will do fine for now, can get to work etc, but I'd really like my MG back! The dealership seems to be spending a lot of time trying to work out what's gone wrong - I suspect a lack of knowledge / not enough engineers with knowledge of EVs. Can't see any way to hurry them up - no point getting shirty, but I do wish they'd get a move on.
 
My ZS EV was off the road for 3 months at the dealers while they tried to find someone qualified to remove the traction battery and diagnose the fault. No courtesy car for all that time either!

In the end an engineer came down from MG UK and removed the battery, diagnosed a faulty module, and parts were ordered. He returned the following week, fitted the modules and all was well.

That's what I was afraid of - waiting endlessly for a fix. I suppose it isn't specifically EVs that have this problem, just any modern cars with software and electronics to go awry....

The only good thing to come out of it is that the Dealer, now that Battery Courses have been made available by MG, have had 4 technicians trained, and they are now an MG battery centre.

Well, I hope that helps! I'll give them a call tomorrow and see where they're up to - they give me the impression of not being on the ball with this technology.....

Who is the dealer - it might be useful to know a dealer that has good battery knowledge.

Interesting - I have had my MG5 PFL SR (71 plate) Exclusive for a year now with no issues. What you experienced is my only worry. I understand things can go wrong but if they can't be sorted in an adequate time it would really annoy me. The MG5 seems to be the most reliable model in the MG range so far. Out of interest would you still buy another MG after your experience?

Probably not. The lack of support from MG UK was disappointing, to say the least. I appreciate that a lot of marques might be the same now, but there was just no empathy at all.

I bought the ZS as it was, by comparison, a lot of car for the money, and I still like it. When I feel the time is right to change it, or if my needs differ, I will look around and see what there is available across all marques in my price range.

I would be hard pressed to decide on a replacement for the MG5 as it has been so good. Reliability is the most important parameter for me - hence the decision to get the MG was a gamble

Similar for me - had my MG5 PFL SR for exactly four years before this issue, the first that's taken it off the road - but it's been 6 weeks now, and no indication that they are any nearer to fixing it. What I'd like to know is, is it specifically MG - or is it any Chinese car - or any modern car built anywhere? If there was some manufacturer that gave top service when things like this go wrong, I'd go with them. Doesn't matter how fab the car is - and I really like my MG5 - but if they can't resolve it when it goes wrong, it's a showstopper for me.
 
I suspect it may be the Chinese thing. Somewhere back in the depths of this forum someone (helpful eh!) noted that customer service was not really part of the deal in China, it was more a case of sell it and then it's yours. Customer service after care being more of a western thing.
Whether that is right or not I do not know but the evidence certainly for MG appears to back up that theorem, as they have a poor notion of how to keep a customer happy when things do go wrong.
 
A colleague’s BMW 3 series hybrid has been in the garage for 6 weeks. Battery problem - they don’t know what’s wrong or how to fix. He does have a 5 series courtesy car but payroll now want to increase his company car tax!

So not just the Chinese that have problems.

One of the directors i4 had complete electrical failure also.

Not a big survey but 2 out of 5 BMW company cars have had electrical issues.
 
Sorry to hear about the issue you're having, I know MG aren't the quickest or the most prepared when it comes to repairs. How many miles has yours done?
I racked up 41k in my previous MG5 over 3 years and the only issue it had was the heater stopped working which took 6 months throughout winter of back and forth with the dealer to fix (faulty resistor). Then the radio screen stopped working just before I sent it back to the lease company and bought one of my own. Still love the car and can accept some issues with them for the price and cost of ownership but lead times for repairs are a joke at best.
 
I had a 2021 MG5LR for 3 years with no problems until I had a minor steering problem which my dealership agreed it should be a warranty claim but unfortunately they wouldn't repair it until they got the green light from MG. After 4 weeks still nothing from MG.
After reading the terms of the warranty which states if you are aware of a problem and carry on driving it your warranty may be void and the dealership said that could be a possibility. The problem was now logged with MG.
I had a holiday coming up 500 round trip and I couldn't take the chance of my steering suddenly failing on the motorway or voiding my warranty so I hired a manual VW for the week. I'd forgotten how much hard work a manual petrol engine was.
