MG4 X Power Vibe/Hum 65 to 75mph

Hi everyone,


Has anyone here had the Stage 2 intervention from technical bulletin TI-20240321-EH32, including the replacement of the engine mounts?
Did it actually make a difference? .............

Yet someone (@ilukey77 in Oz?) reported that the "expensive" fix did work for his?

yeah mine was fixed im in Australia .. still fixed. took it on the freeway just the other day and it's still great ..

As for cost the list ( that I've posed in previous posts ) is long so i ASSUME it's not a cheap fix.

Talking: motor out ,sub frame replacement ,bushes ,fluids replacement etc etc ..

I think the car was worked on for 3 days or so , so labor alone lets say at 100aud an hour wont be cheap !!

The characteristic BS is based on parts and labor costs.. ( that MG dont...

yes I've had the fix done and it's still good ..

don't know what stage 2 technical bulletin thingy you're referring to, there is a post somewhere in this thread with all the parts replaced on mine under warranty ..

A lot of bushes and subframe parts were replaced so motors out etc etc ..

I can safely say it has fixed mine since Feb / March this year, still no vibes ..

any vibes i do get now are purely road surface, not the issue that has been fixed..

hoping the lowering doesnt cause issues, which will be done by the end of this month ..

Just clocked over 30,000 km in it and for the most part the car is still plugging along fine !

no serious issues. i did have an issue, directly after charging it would have a HUGE clunk and I'd get a "cannot select gear" warning light on dash. happened a few times, took it to dealer; couldn't fault, it hasnt happened since ..

Ohh and i had a really loud constant screech from rear brake on one side. drove to dealer ( typically stopped just before i got there ) dealer bent some brake backing plates a bit, mechanic said is was probably just stone caught in there ..

otherwise for my 30k done ( other than the vibe and a few standard stupid design / software issues), the car performs well ..

I get it in drive it no real hassles and it hasn't left me stranded or broken down ..

Almost amusing that the most break downs I've had with my cheap Chinese car is not the car at all, it's the disgusting charging station near me that is constantly breaking down.

Mine has settled down (mostly). I find keeping pressures up helps. Still not has smooth as my partner's LR77 but most of the time I don't notice anything, then it may become noticeable for a few minutes.

Mine has settled down mostly as well. Higher pressure works for me, but additional to that, I think higher pressure at the rear vs the front. Right now I am running 43psi rear and 40 psi front (cold). I had to carry a full load recently and noticed this was recommended on the info plate near the driver's door. Ended up leaving it like that and the vibes have been really minimal. Might be worth trying out for anyone still experiencing issues.
