Noisy power steering - the car was supposed to have had a recall modification, but despite being supplied, serviced and resold by the original dealer I had to tell them about the mod after contacting Vauxhall. By the way, this was a Network Q car - 144 checks, but none carried out.
Clutch judder - Dealer and Network Q refused to repair despite another dealer assuring me there was a problem - a well known one.
Fuel supply problem - again dealer and Network Q refused to do anything about it despite an independent report saying it was a known carburettor problem.
Rear wiper stopped working - gave up trying to fix this.
Leaking fuel pipes within weeks of purchase. Dealer refused to show any interest and said it was not covered by warranty - I drove up there to buy the replacement pipes and went into the showroom to express my feelings. The salesman immediately arranged for it to be repaired - the fact the showroom was busy may have had an effect. THIS IS A WARNING TO ALL VAUXHALL OWNERS - These fuel pipes failed on my previous Astra (AN EXCELLENT CAR) after approx three years. I know a number of people who have had the same problem including one who's Carlton caught fire when she had three children in the car - the pipes concerned are black with a "thread" braid - Despite me writing to Vauxhall four years previously they were still using these pipes and to my knowledge never recalled them.
