I have only had 3 problems.
The fuel gauge had to be re-calibrated on a number of occasions as it kept showing the wrong fuel reading, the dealer finally replaced the offending part.
The radio loudness button is continually on.
The radio player will sometimes stay on after the engine is turned off no matter what I do.
I have had a number of vehicles from various manufacturers as my family has grown and it was a toss up between the Picasso and the Zafira.
The Picasso won hands down.
The price is right, it has more internal space and comfort, very economical to run.
I have already travelled to Holland in it and look forward to our trip to Italy.
The radio can be programed to stay on after the car is switched off... read the manual.
