Hi I bought a car 3 weeks ago tomorrow and on Monday it started making a funny sound in the engine. WhenI I put the car into drive, reverse or come to a complete stop, the car makes a clunk sound and the oil filter light flickers on and off. I took the car back to the dealership yesterday and they have booked it in to look at it on Monday but have said anything that needs fixing I will need to pay for myself. When I purchased the car, I asked about the warranty and was told because the car had more than 16,000 kms, there was no warranty, so I asked if there was an extra warranty I could purchase and I was told no. Is there anything I can do since the car is only 3 weeks old in regards to them fixing the issuess?
