Car issue from dealer after just over a month of ownership
I bought a second hand car just over a month ago from a dealership. While driving the car, the engine cut out, and it would not start again. I contacted the dealership and got it into a repair shop through the mechanical warranty. I want a refund on the car, as according to the checklist on the consumer guarantees website, "it did not last a reasonable time", and I would imagine that the full engine replacement that has since been decided by the repair shop as needed constitutes that it is not "an easily fixable problem".
The dealership has rejected my claim for a refund as expected. They say the vehicle passed all their mechanical testing/checks before sale, and wants to just go through the warranty to fix the issue. My problem with this is that a complete engine failure after barely over a month of ownership would likely mean there was a latent issue that was overlooked by whoever did these checks. This is also supported by the repair shop as they have also said there was most likely a latent issue. I do not have this in writing as of right now, only over a phone call as it has only gone into the repair shop today.
I am looking for advice as to where I stand regarding getting a full refund, where I should go from here, and what kind of course of action I should take if the dealership continues to push the engine swap through mechanical warranty. Thank you in advance 😄
