Mine is sometimes reluctant to let go when I engage reverse. It has failed mid-journey once - MFD warnings for both handbrake and autohold. I took it into Benfield the other day for that and other warranty work. Georgek says it needs a recalibration of a host of sensors. I told them this but all they did was clear the memory log of the fault. Tonight the same thing happened again - complete failure of the system, and restored functionality once the ignition was turned off, key removed, reinserted and ignition back on.
Will be taking it back and also give them a piece of my mind about how they took my car for a 28 mile trip following suspension top bearing replacement. A mile down the road and going over a few speed bumps would have ascertained that the car was fixed of squeaky suspension.
