Hesitation when Accelerating

[KayCee]

A few times of late if i am doing around 50 /65 and i accelerate there seems to be a bit of a lag as though the car is not sure what gear to be in i know that cant be right because its a CVT but thats how it feels it  is like Turbo lag on turbo cars it doesnt do it all the time just now and then

It had the plugs changed at last service September last at Sheffield before i go and enquire as anyone had similar experience of this I am obliged for your replies . I have had car over 2 yrs without any issues and also took out extended warranty which incidently runs out this September and i will be renewing the car as done 55k or there abouts

TIA

Hi,

450h gearbox got 2 gears CVT achieved via a "reduction device". 1st gear is used for acceleration from 0 while 2nd is for max speed. Gear change is occurring in the 50-60mph area and it is that lag you are mentioning. If you check 300h spec which doesn't have that reduction its max speed is limited to like 120mph due to that.

Have you ever changed gearbox oil ? Probably  not and hence gear change is getting little bit slow/noticeable over time. In my previous GS I've change it at 100k miles/6 years and gear change get better after that - but still noticeable which is perfectly fine. 

Last option is faulty oil pump which was common in early model but should be fixed from 2008.

My transmission oil was changed last service. That was a 4 year service.
