Subaru SUV Range

Before you commit to any costly course of action, go back to basics. A car that jumps out of gear might have a poorly adjusted shifter or linkage mechanism rather than something internal to the gearbox. Even a worn engine or transmission mount can allow enough movement for the car to jump out of gear. So check that stuff first.

In terms of rebuilding a gearbox like this one, you may find the cost is greater than the retained value of the vehicle. Not to mention, with that sort of mileage, that you’ll lie awake at night wondering what’s going to break next. At that point, you have to make a call. But don’t forget, you might be able to find a second-hand gearbox in good condition at a parts recycler, and have that fitted for a fraction of the cost of an overhaul. And then you’re on your way to your second half-million kilometres.

It sounds like the head unit and its Bluetooth functions have suffered a pretty major electronic failure. The good news is that you can replace the head unit for reasonable money these days, and get a better unit with more features into the bargain.

But before you rush out and replace the unit, try to find the reset button (often a small hole into which you poke a probe) to effect what is basically an Ctrl-Alt-Del reset. This will sometimes restore the unit to full functionality, so it’s definitely worth a try. You could also try disconnecting the car’s battery overnight to see if that resets things.

You may have something loose or worn in the driveline – such as a driveshaft – that is causing the thump. Looseness or wear means the drive from the engine doesn’t travel smoothly to the wheels, and that’s why you hear a noise and feel a clunk when you engage a gear. A check underneath should easily spot the problem.

But you may also be dealing with a worn transmission with internal wear. The Subaru XV uses a CVT transmission which, while a very efficient design, is also known for developing wear. This isn’t just a Subaru problem, either; many makes and models with CVTs have the same issues. CVTs are definitely stronger than they used to be, but they’re not always the most robust type of transmission.
