I have just purchased a brand new MG ZS and the cruise control functionality is inconsistent, when using the lever to accelerate or de accelerate via the one mph increments. Sometimes it misses and you have to activate the lever again, sometimes it doesn’t work at all and sometimes it just jams the whole system up, meaning you have to turn it off and back on again to regain its activity.

The jamming up occurs, during deceleration when the speed reaches a figure that contains a 7 or a 2 in it, very strange and annoying. For example, if you decelerate from 40mph to 35mph using the 1mph increments it will jam at 37mph. If you decelerate from 35mph to 30mph using the 1mph increments, it will jam at 32mph. This happens in the 20’s, 30’s, 40’s, 50’s, 60’s etc…..

Has anyone else experiencing the same problem?

The car has gone back to the dealer once and I got the usual response “we can’t locate the fault”, the car is due to go back to the dealer again, the fault is so obvious it’s ridiculous they can’t find it. I read on this forum (different thread) that MG are aware of the problem but can’t or won’t fix it.

As I said, very very frustrating and annoying :-(
