Hi Hayley, best recommendation from Jimboy !
Your car has a warranty, even 'little', the minimum to be covered is the powertrain (engine & gearbox): the seller have to fix any issue that existed at sale or occurs during the warranty period.
Usually it is an insurance that the seller contract so they don't even pay from their Pocket if Something needs to be done (well I guess in certain limits…) unless they took the 'risk' on themselves …
You should not feel bad by insisting upon them that you bought a car that has deffects that need fixing, very good advice to be accompanied by a 'mature' Guy, even better if he knows a bit about mechanics !
Beside that, the clunks and hard to select gears are probably the results of the bad engine mount(s), how many of them have been replaced ? There a three in total, my guess is they only replaced one, which only partially solved your knocking noise issue. The BG cables have maybe been stressed by the engine's unwanted motion and need re-adjustment.
Take already the good habit to keep us informed …
BRs, Bernie
