Is anyone else having same issue ?

Here's your main thread about this. There have been a couple of others started since by people who also noticed the fault. Is yours the SR battery? Because it seems it's always (usually?) the SR that's affected.

Big shot in the dark that anyone else has experienced this, but worth a go. My drive home involves a short blast up a dual carriageway from a set of lights, bit of a Grand Prix to be honest. Twice now I’ve floored the car up it and it’s resolutely refused to do more than 71-75mph. It’s not a...

Worth reading through it.

Until a couple of weeks ago I think most people on the forum would have told you to give your car back and demand a refund and run a mile. The fault has caused a number of people, particularly Bowser, an enormous amount of grief. However, about the end of July, an update to the battery management system came out which seems to be being applied to all SE SR cars (mine had it on 31st July, although I never had this problem), and the people who were affected are now reporting it's OK. I don't think any of them have come back and said the fault has recurred.

So if it is the same fault, and this update is the cure, you need to get your dealer to do it. But be firm with them. This fault can be an absolute bugger and several cars have been rejected because of it.
