MG ZS Hybrid+ high engine revs

[Mal Knox]

I agree the over reving is my major concern with my ZS hybrid starting from day of delivery . I live in the Blue Mountains and regularly experience 3500-4000 RPM , the noise is cringe worthy. Passengers regularly comment but the authorised service state high revs should be expected as a feature of the design. I would feel much better if MG could state on paper that revving of this magnitude is a normal feature and will not be detrimental to the life expectancy of the petrol motor.

I too have experienced this high revving issue in our Hybrid+, but at higher revs than stated on this post - up to 4500 in most cases and not always going uphill, but usually. I know that our MG dealer knows about this but refuses to acknowledge its existence. I have represented this problem to other dealers here (Victoria Australia) and they too seem to be just looking the other way, for now anyway. I have heard of a software update available in the UK (but not universally so) that appears to fix this issue. I’ll be pursuing MG in Australia to address this issue as it cannot be justified as ‘normal’ by any stretch of the imagination in my view.

Not sure if your hybrid+ does have the latest software. I got my hybrid + in mid-February and was assured that it had all the available software updates then. The only software update that I'm aware of here in Melbourne Aus just addressed the problem of the software allowing the battery to drain down to around 10% before the engine kicked in to re-charge thebattery. This reportedly caused a loss of power and excessive revving to replenish it. After the software update the re-charging starts earlier when the battery gets to around 40%. I too can experience high revs going up hills whenever the battery falls below 40% but the car can still maintain it's speed. It concerned and embarassed me greatly to start with but I'm now much more relaxed about it, knowing that it's simply re-charging the battery. I've also found that gently easing off the accelerator a couple of times can help reduce the revs and appear to go into a lower gear quicker. Not ideal, but apart from this I'm very happy with the car.

I’ve had the same issue with my ZS Hybrid+. It consistently happens in the same spots on the road — one of them is on my route home, so I hit it daily. For no obvious reason, on a slight incline, the car suddenly revs hard and I’m behind a screaming motor. I’ve also noticed that if I decelerate around 3–6 km/h, it sometimes drops a gear, but not always. The behaviour feels inconsistent. Car hasn’t had its first service yet, but I’ll be asking the dealer to check for software updates when it goes in.

Just been out today in wales at 23 degrees. Revving at 4500 whilst doing 45 on the flat, rarely goes below 2000 revs except when on EV for 30 seconds. On same 45 mile journey last December I got 76mpg, today I got 55. There is a group on Facebook specifically for the over revving with a view of going legal but it is UK only at present. There is something wrong with just a small minority of cars which means MG are ignoring the complaints but it's extremely annoying if you have one of the problem cars

Do you have the link for the group on Facebook thinking about legal action, my son would like to join as having the same problem.
