Re: the ride. Check tire pressure, it could be too high.

Also the central locking does not work, and interior cabin lights don't turn on when closed or open and the rear door open light is always on despite it remaining closed.

Those problems are all likely caused by one thing - the system thinks the rear hatch is open. Fix that and I bet you can use remote locking and the cabin lights will work again.

We can't say if this is something you can handle or not. It does involve needing to know how to use a volt meter, and possibly removing the plastic inner panel(s) on the rear hatch. I suspect the rear hatch door open switch is in the rear hatch's outside door handle somewhere.

Maybe, but my 07 Accord has 211,000 miles on the original suspension components.
