Car purchased for ~ £7,500
What I've done so far: Raised the issue to the dealership from the day after I found the fault. Have it in writing that they will commit to sorting this issue beyond the 3 month warranty. After a lack of communication from the dealership, refusal to pay for some of the diagnostics and refusal to accept rejection of the car, I contacted my finance company (as they still own the car).
What has happened since purchase / complaint: Took the car to Honda to get diagnostics and regeneration, which did fix the issue for around 1 month. I raised the issue with the dealership again 29/08/2016, noting that this issue was present again. The dealership asked me to take it to a local dealer (not Honda) to get diagnostics. All local dealerships said they could not carry out the diagnostics and it would have to be Honda. The dealership did not agree to this then cut communication. I have email chases from myself asking for a response. It took until 26/09/2016 with constant phoning before they spoke to me again. The response reads:
"Should they (Honda) find any underlying issue as to why the car is not regenerating itself, then we can address that, possibly with a local VAT registered garage, if that is the case, should the fault fall within items covered under warranty Dace Motor Company will cover the cost of repair within the terms of the warranty, even if the repair takes place outside of your warranty expiry date."
Diagnostics were carried out 04/10/2016 and found no fault. Honda suggested replacing the DPF. After speaking with Dace, they told me I had to price getting this done. I did this and got no reply. I then emailed on 23/11/2016 stating:
"I've tried calling you several times now and have had no reply from you despite you telling me you would get back to me weeks ago and reception informing me you would phone back when I've called in."
I only received a response via phone at the start of December stating that Dace had found a much cheaper alternative and wanted to send a DPF to a local garage for them to fit. I was reluctant to do so, but this was the only option offered. The work was carried out 20/12/2016.
Replacement of the DPF did not fix the issue, the light was still on and the car still in 'limp' mode. I was advised by the garage that the DPF may auto-regenerate after driving for a bit and clear this fault. After several attempts at this under the recommended Honda guidelines for DPF regeneration, the problem still remained. The garage then performed a manual regeneration to see if they could clear the fault and were unable to. Further diagnostics were done and again, no fault found.
I emailed and called several times again before getting to speak to someone, I requested that the dealership take responsibility for the car and repairs, noting if they did not I'd be looking at getting the car rejected / refunded. Their response was that this would not happen, and that I should take the car again to Honda for diagnostics, but that I should pay for it. I emailed again 09/01/2017 refusing to pay for diagnostics, and again asking them to do so. They replied saying they would pay for the diagnostics but only if there was a fault code relating to the DPF. They also noted that if there was not a fault code for the DPF they would not pay for the diagnostics or any subsequent repairs as it would be something new that has happened to the car and is now outside my warranty.
At this point I immediately filed a rejection request with my finance company, who suggested I take it for diagnostics and they would pay if Dace wouldn't. They don't seem to want to help, and keep bringing up reasons that I shouldn't reject the car. Their latest correspondence notes I only had 30 days to reject the car and I've only raised it with them after 7 months.
Sorry for the length of this and if I missed anything, I tried to be thorough. I just don't know what to do now. I figured the finance company would help me with this process but it doesn't feel that way. Apart from going down the legal route, I'm not sure what I should and shouldn't do. Any advice would be very much appreciated!
