Well, 9 months on... as I mentioned, I only do a small mileage now, so only 5-6000 more than when I bought it. A few niggles, but nothing really concerning:
1. I HATE the infotainment system - it seems to have a mind of its own, changing default settings from time to time, and all sort of other little weirdnesses with it. Particularly loathe the loud, blaring "service messages" every time you do something, eg bluetooth device connected, rain sensing wipers activated etc. And don't get me started on the "touchpad". But... the Rover only had a basic stereo, so this is handy.
2. Passenger side power fold mirror sometimes sticks, or otherwise misbehaves. I'm pretty sure it has the same guts as the Rover ones, and they were shite.
3. Love the way water pours into the boot if it's been raining heavily, and you lift the boot lid - somebody has put a lot of thought into designing it to do that.
I could go on about things like that but as I say, they're niggles. I really like the car actually - MUCH more powerful than the Rover (which was theoretically mapped to the same bhp), while only losing 3 or 4 mpg to the auto box (the 75 was manual). Comfortable and relaxed; handles more than well enough for an oul man like me.
PS another niggle is the button you press on the gear selector - it's kind of sticky. I did post on another Insignia forum, asking if I could squirt some lube into it, but just got a series of teenage style comments about knobs and lube
So not sure whether to try squirting some silcone spray into it, or maybe getting a new knob assembly from eBay
Anyway, no reliability issues yet...
Cheers
PS I suppose I should say that my poor next door neighbour needs a new engine for his something about the oil pump failing, from what he said. It's been off the road for a good two months now, while he argues with the dealership, Vauxhall etc about who pays for it.
His is the newer shape model from mine, maybe 2019 reg (hard to tell with our NI system!)
