Persistent problems with the rear brakes. They are noisy when reversing and braking. The dealer has already attempted to resolve the problem twice by replacing the pads (at 7000 miles) and subsequently making a Vauxhall recommended modification. On both occasions the fix worked briefly, but the problem returned. It seems that the calipers are a problem with the Zafira.
The paintwork seems to scratch and mark very easily. Although this is not a problem from a rust perspective it is annoying in cosmetic terms.
The handling of the car is very good for a seven seater. I have previously driven the Galaxy and Ulysse and would rate it better than both.
Fuel economy is decent, coming in at about 41 to 43 miles per gallon. Not a patch on my old Montego diesel, but you can't have everything.
Seating is very comfortable and the two rear seats are excellent, considering that they are the fold-down ones.
I had this problem with the brakes also.
The dealer fitted dampers 6 months ago and it seems OK now.
