The day after purchase the idle of the car became erratic at stand still. After a few days of this occurring, I took it into a local garage to be informed that the idle valve was sticking; this is a common fault with Ecotec engines of this age and mileage. They cleaned the valve and all was good for about 3 weeks, although the garage did inform me that this may not fix the actual problem fully.
The problem then started again with the revs increasing at stand still. £240.00 later - a new idle valve and labour, the car was going fine until the alternator decided to fry the electrics on the way back from work! Smoke appeared from behind the dashboard, so I pulled over and called the AA; they came and said the alternator was increasing voltage to all the electrics.
The car went back to the garage - £250.00 for a new dashboard - second hand alternative (cheaper), and £190.00 for a new alternator.
I've had Vauxhall cars for years, this has been the most problematic car I've had.
It's a shame, it's a lovely car to drive, very comfy and handles like a dream. Downside is the faults that have occurred and the fuel economy is poor.
The cabin is spacious, and although some may say it looks dull, I feel the GLS spec looks more in keeping than the false wood found on the CD models.
