I bought a new Hyundai ix35 a few months ago from an authorised dealership. As part of the deal, I had front parking sensors fitted by the dealer, as they’re not standard Hyundai parts. However, upon collection of the vehicle, I found that the sensors were not working.

The dealer has inspected the car three times now, but the sensors still don’t work. At this point I no longer want the sensors, and am unwilling to add more miles to the car and pay for fuel to return the car to them again. What are my options? Can I insist on a refund and their removal? Do I have the right to any compensation for the wasted time and fuel spent returning this car to them to have the issue investigated?
