I've been very pleased with my 2015 VW Passat until recently. Great fun to drive with ~300bhp and bucketloads of torque, super practical with its cavernous estate boot and pretty reliable - until now 
I had a full main dealer service and MoT at the end of January, it flew through with no faults or advisories. 6 days later my wife borrowed it to drive to work as there was 10" of snow on the ground and we decided the 4WD would be a benefit in those conditions - she works at a Hospice so had to be on site. Unfortunately she didn't make it - the car overheated and she got stranded halfway in a Tesco's car park. The car went back to VW where they diagnosed a failed water pump, the replacement set me back £480 even after a goodwill discount. Pretty frustrating, but these things happen. 8 days out of warranty I might add, hence the small discount.
The following week I had an error light pop up on the dash, EPC - or Electronic Power Control - and the car went in to limp mode. Bugger. I scanned the car and found the error was related to one of the Turbo wastegates getting stuck open and popped in to my local specialist. We were hopeful that it would be an easy fix but alas no, the wastegate was partially seized and non-serviceable. Apparently completely unrelated to the overheating incident and just pure bad luck. It's now in having one of the turbo's completely replaced at an eyewatering cost of £2,150, bringing the total maintenance cost so far this year including the service and water pump to just shy of three grand. I thought these things were supposed to be reliable
I'm now trying to sell my Di2 Brompton project to help pay for it, sad times 
What makes it even more frustrating is I was due a company car on 1st Jan but the new fleet management company have screwed up the handover - if it had gone properly I would probably have sold it on by now, and someone else would be selling their possessions to fix it
Urgh...
