Repeatedly stalls and loses power, terrible in wet weather, and completely unreliable
Mass air flow meter.
Central locking has needed to be fixed so many times I gave up.
Multiple tubes and pipes.
I took out a loan to buy a car, which I hoped would last my whole uni degree. This car lasted a year before it became the most unreliable and worst investment I had ever made.
The car is manufactured and designed so badly, mechanics would have to trial and error the multiple problems that occurred within the car, simply to pinpoint the actual issue. For example, it has an air pipe less than a centimeter in diameter, which would clog up and cause various other tubes to block, and the car to cut out repeatedly - an extremely common problem apparently.
This took ages to pinpoint, and the car needs to be regularly 'unblocked' every few months - this is also very dangerous when you lose all electrics and power steering in heavy traffic.
My Vectra has had multiple problems every couple of months which have been very hard to locate the source of.
Scared of driving it due to its complete unreliability. I'd had enough, and worked my ass off to pay the loan a year early. Dumped it in my yard, and bought another car as I would not sell a car this unreliable to anyone.
Would you buy another car from this manufacturer? No
