somethings gone wrong with the MG ZS. went to drive into town tonight,
and the car accelerated normally until it got to 40 klmph, then it
stayed at that speed. it wouldn't go any faster. the accelerator had no
more effect. the speedo needle stayed rock steady on 40 klmph no matter
how hard I pressed the accelerator. It was hot today, over 30 degrees I
think, but there were no warning lights on the dash. any ideas before I
contact the dealer?

That could be indicative of going into limp home mode. No engine lights
on and did it drive normally after after cooling down and/or cycling the
ignition?

It could be anything from an O2 sensor to something more serious but
really your best bet is to contact your dealer and have them look at it.
It is under warranty so...

I haven't tried it since I drove home. I will try it tomorrow, and ring
the dealer

As Clocky said, it seems to be limp mode. It's a safety feature that
allows the car to be driven home albeit at a low speed/power. Often it
will only allow 1 transmission speed. Did your MG clear itself once you
got home and cycled the ignition?

If now warnings came up, that would be strange. A code reader would be
handy, or a scantool. I'd check that the battery voltage is OK. Should
be >12.6 measured at the battery. Most cars these days have a battery
voltage sensor on one of the terminals. If it is faulty or has a bad
connection, strange things can happen.

Anyway, they have, IIRC, a 7 year warranty - go test it out.

started the car yesterday morning. it seemed to be running a bit rough.
took it for a short drive and it's running ok. drove to the dealer for
them to check it out, and also to have the first service done. picked up
later in the afternoon. they could find no fault, but they updated four
computers. they said it was most likely a 'glitch', which is known to
happen with modern cars that typically are loaded with electronics. they
also said if it happens again, as you and clocky did, to cycle the
ignition. hopefully no more probs. :)

That's not really typical these days (well decades actually), for such
'glitches' to not set some kind of code, history code or other telltale
that would indicate a problem.

Looks like MG have a very long way to go. Hope it all goes well, but if
it does happen again do not accept the car back unless they have found
the fault and fixed it. It is a pretty significant safety issue after all.

If the problem is severe enough to drop the car into limp mode, then it
should be setting a code related to the cause and said code should be
present in some form - even if only historical.

You might want to Google to see if other owners have had similar issues
pop up and if MG found a problem or what fix they applied.

It could well be just a firmware issue that is now fixed with the latest
firmware updates. If they are like Ford they won't even admit to a
common fault that they will claim "have not seen before" or "couldn't
fault" after applying a service fix.

You've accidentally set the speed limiter. Had the same thing happen on
an MG hire car I had a couple of years ago. It's enabled on the same
stalk as your cruise control and it is a PITA when it happens.

It's easy to do on some Hyundais as well, where the cruise button also
sets the speed limiter depending on how many times it's pressed. It's
easy to press more than once and engage the limiter.

tonight, and the car accelerated normally until it got to 40 klmph,
then it stayed at that speed. it wouldn't go any faster. the
accelerator had no more effect. the speedo needle stayed rock steady
on 40 klmph no matter how hard I pressed the accelerator. It was hot
today, over 30 degrees I think, but there were no warning lights on
the dash. any ideas before I contact the dealer?
You've accidentally set the speed limiter.
That'd be my guess, too. Hi Grumps :)

Had the same thing happen on an MG hire car I had a couple of years
ago. It's enabled on the same stalk as your cruise control and it is a
PITA when it happens.
It's easy to do on some Hyundais as well, where the cruise button also
sets the speed limiter depending on how many times it's pressed. It's
easy to press more than once and engage the limiter.
So, the Hyundais are no further *advanced* than the Chinese cars. Same
glitches, same poor design - and they've been in the market for decades
longer.

Well, that figures! Explains why Korean cars don't figure in my future.

So a firmware glitch then. Needs a redesign/update to change the
operational mode.

No, pressing the wrong button was the issue. Nothing to do with
firmware, all to do with operator error.

That *is* the problem - dual function button. Needs a firmware update to
reprogram the function to something sensible and *user friendly*. If
users can make simple mistakes like that and *unwittingly* create an
error condition, then the design team need to work on the *user interface*.

Assuming that is the issue, I would call that a design flaw that a
firmware update could surely fix - and probably has been after the update.

You've already proven you're dangerous when working on cars, Les' engine
is proof of that.

I'm not aware of anything like it on the cruise stalk, but I'll look in
the manual

thanks. I'll look into it
so you're correct. I made this pdf from the manual ..
https://auslink.info/files/speed_limiter_MG_ZS.pdf

however.. I did not experience the 'kick down' effect when pressing the
accelerator, even all the way down. so I'm going with 'limp home' mode
as the cause in this case.

Well if you pressed the accelerator down past 80% and nothing happened
it's not the ASL.

Looks like it since doing that automatically disables the ASL. I think I
prefer the system on my Toyota.

Looks like it's just a *package* that the manufacturer buys from OEM
suppliers if Hyundai use the same or a similar thing.

We'll go with firmware glitch then. Probably updated by the dealer,
first thing they do when they get these weird little issues.
