There’s nothing quite as worrying as turning your key and hearing the engine struggling to turn over, as you know your vehicle may have an issue preventing it from starting right up. Our cars rely on various components working together to get the engine running, and a failure in any of them may lead to a hard start.
In this article, we’ll go over the common causes of slow starts on Subaru vehicles, how these issues occur, and what it could mean for your vehicle.
Common Causes of Slow Starting in Subarus
Weak Battery
As possibly the most well-known cause of slow starts, your Subaru’s battery is a good place to begin. When automotive batteries lose effectiveness over time due to old age, cold weather, or other sources of battery degradation, the vehicle won’t have the necessary charge to get the engine turned over right away.
If left to linger, a weak battery can quickly turn into a dead battery and prevent your Subaru from starting entirely without a jump-start, which is why replacing your battery after any signs of weak charge is a good idea.
Faulty Starter Motor
The starter motor is one of the most important components for getting the vehicle running, as it’s responsible for turning the vehicle’s flywheel, and in turn the crankshaft, to draw in the fuel and air the engine needs to run.
An old or struggling starter motor can lead to slow starting, and if it fails completely, the inability to start your vehicle. Listen for any unusual sounds when starting your vehicle, as it could be a sign of a starter that’s on its way out.
Ignition System Issues
The ignition system, which includes components such as the spark plugs and ignition coils, is what ignites the air-fuel mixture within the combustion chamber. With such an important job, you can imagine how any issues in this system could lead to problems starting the vehicle.
Electrical Malfunctions
Subarus, and all modern cars for that matter, rely on a wide variety of electrical components to keep each system running properly. When any of these parts experience failure, such as burnt out fuses, shorted wiring, or corroded connections, it may prevent the engine from turning over as quickly as it should.
