Clutch faults.
Common clutch slips are usually caused by oil on the friction plate or a in some cases vehicles which the clutch is badly adjusted. Its symptoms could include total drive loss and vehicle speed lower than normal compared with engine speed
Leaking head gaskets:
Head gaskets seem to be the bane of Subaru’s existence. It’s an issue that the company can’t fully shake. With that said, current iterations of Subaru’s models have greatly improved head gaskets, and you’re far less likely to find issues with the gaskets in a Subaru that was made in the last decade (though it still remains a minor issue). Head gaskets in the late-90s and early 2000s, however, were a serious problem, specifically in the Outback and Forrester, but also in the Impreza and Legacy. With models in those years, you can almost be guaranteed that the head gaskets will malfunction, and sooner rather than later.
Knock sensor malfunction:
Subarus are known for having the knock sensor malfunction. The knock sensor essentially listens to your engine, to gauge that it is firing correctly. If it hears otherwise, it will alter the engine. When the knock sensor cracks, it falsely hears issues with your engine, and then adjusts incorrectly, which hurts both your performance and your mileage.
THINGS TO DO TO PREVENT AND HANDLE THESE PROBLEMS
Take it to a mechanic: It goes without saying that when these issues occur, they must be fixed. It’s important to take your Subaru to a good mechanic. For Subaru owners in British Columbia, give us a call at Collins Automotive. One of the benefits a place like Collins Automotive is that we are not a Subaru dealership, which means that, in the case of the discontinued tire issue, we can seek out the one tire you need, rather than forcing you to purchase four new tires.
Do your research: Once the head gasket is replaced, most users report that their vehicle will go 250,000 – 350,000 kilometers without gasket issues. Save yourself time and hassle by purchasing a Subaru that has already handled this issue.
Be thorough: When you notice a warning signal (such as a funny noise, or leaking oil), take your car to the mechanic. Chances are you have a small issue that can be resolved before it becomes a big issue.
