MG3 Underbody corrosion

Jim Jamieson · 11th August 2017, 09:02

This is a common problem with most manufacturers nowadays, the underside components are simply not coated sufficiently to protect them from rust.

This week I was tidying up my sons Mercedes CLK and I noticed the rear subframe and components are encrusted with rust.

It would have gone like this at SA..

Meeting to discuss under body coating.

Present: 30 Chinese SA guys and perhaps the odd rover guys.

Decision to put 3 microns of coating on, saving 10 rmb per car..

Job done retire for huge banquet dinner...Gambai

Em I'm not so sure.
The Panda is a year older and has 7000 more miles under it's belt, plus lived in Stevenston for 2 & 1/2 years Jim. Other than a tiny bit of rust at the weld from the rear beam to the torsion arm it is rust free.
Mercedes still have rust issues on suspension areas, why are these areas not galvanised is a mystery.
I have though Waxoyled the Panda throughout as a precaution.

On a different note the young salesman in Brysons MG told me that sales are poor, the lack of advertising doesn't help and a few horror stories are coming to light, namely clutch issues and timing chains stretching and jumping teeth, MG customer service is hopeless with letters, calls and Emails ignored, at this rate they will disappear and owners will get nothing for their cars.

Hi.
On a slightly different note, after a lengthy discussion with an MG dealer service manager that I know from my previous job. I was told off the record that three things are problems. Timing chains stretching, MG blames customers for lack of timely services, he believes that its nonsense, clutches that last 30,000 miles if your lucky because they are toffee and no proper under body protection.
I am so mad as these cars were to be done right with UK input. We have already seen MG making jobs go here and it now looks like it's just Chinese tat.
I feel for my daughter landing up with a car that may not last the pace.
My old Skoda cars were better engineered.

Open the oil cap and look at the chain..... It's a joke. It needs a proper duplex chain of the same pitch BMW used in the neu classe 1500, through the 2002 to the E30 and what Skoda used in the 1000mb to the last Skoda powered Fabia.

Already they are are worth nothing from the moment they are driven out of showroom might as well burn money....

Not just MG's. My Evoque has had the fuel tank cover replaced at just under 5years.. it was totally rotten. LR said it wasn't covered

murphyv310 · 12th August 2017, 14:21

At this rate I see the sales of Waxoyl going up!!!

The new cover is totally different and not made out the cheap steal that the other was. Looks like ALL manufacturers are cutting costs. I saw a new Mercedes C class with vinyl seats the other day... the owner claimed they were leather until I got up an Autocar article which confirmed them as vinyl

Its all down to cost I'm afraid, at least the MG3 is good value, where as a Rangey isn't.

You do have a corrosion warranty though.

As for timing chains, that was an issue on earlier cars, hopefully now sorted.
