I bought a 2015 Citroen C1 with 26,000 miles on it six months ago, which was serviced before I had it delivered. A month in, I first used the horn, and discovered it didn't work. Along with this, the gears were grinding and the clutch had risen since purchase. I took it back to the dealer, where they detected no faults with the gears/clutch. They routed me to a closer Citroen dealer for horn replacement and a second opinion on the gears/clutch. The second garage found a fault with the gear belt. They took it out, cleaned it and sent me on my way. I returned the car again in January for its third annual service and another look at the clutch and gears because it was grinding more and the clutch had gotten even higher. They found no faults again and the car passed its service. A few days ago the car slipped out of third gear and wouldn't go back into gear. I have returned it again as the clutch is so high it's unbearable to drive. They told me the clutch is at the end of its life. My extended warranty isn't going to apply and I have to pay. What are my rights here? I have expressed my concerns three times before anyone actually listened to me. Not to mention the car wasn't serviced correctly before purchase as it was sold with a faulty horn.
