Subaru Reviews

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.

Subaru’s own brochure blurb for the Crosstrek features the promise of off-roading family fun. With that in mind, the warranty will still apply even if you do get adventurous with the vehicle. That said, you might have warranty problems if it’s deemed that you’ve abused the vehicle by trying to take it places it was never designed to go. For example, while the Crosstrek is fine for finding a great mountain bike trail somewhere along a forestry road, trying to drive it up the Old Telegraph Track to Cape York through metre-deep river crossings is not within the Crosstrek’s design brief. Doubtless Subaru might argue you should have bought a high-clearance off-roader with a snorkel for such adventures.

The CVT is Subaru’s own work and design. While many other carmakers buy in transmissions from outside manufacturers, the CVT in the Crosstrek is an in-house effort. It’s generally agreed that Subaru’s CVTs are better than some other brands in terms of durability and reliability.

The noise could be from the electric motors themselves or in the gears and cogs that physically move the mirrors to their new positions. Pulling the mirror apart and lubricating these mechanisms might help reduce the noise and may even fix the one mirror’s reluctance to move through its full range of positions.

As far as warranty goes, the situation is a bit complicated in that the dealer may examine the noise and decide that it’s not abnormal. But what you should do before the warranty runs out is have the car examined and the problem logged at dealership level. That way, if anything goes wrong as a result of the problem, even if it’s beyond the warranty period, you have what’s called a pre-existing condition whereby the problems is Subaru’s to fix because it existed while the warranty was still current, even if it wasn’t fixed at that time. The point being that the dealer can’t delay a fix reported during the warranty period and then claim that the vehicle is out of warranty and refuse to fix the problem.
