Within the automotive industry, Subaru is renowned for reliability. Legions of loyal ID Subaru fans can attest to the durability and longevity that distinguishes every one of the brand’s sedans, wagons and SUVs for sale on our lot. The data backs this up: over 96% of Subaru vehicles sold in the last 10 years are still on the road today. It’s a fact our Subaru dealership near Boise is particularly proud of.
Yet the impressive Subaru reliability record does not mean these vehicles are infallible. Your Subaru engine, like all gas-driven powertrains, is a mechanical symphony consisting of hundreds of parts working harmoniously. Without adequate maintenance, even the best Subaru engines can eventually require more substantial servicing.

Engine failure can manifest in a variety of ways. More obvious engine failure warning signs can include the illumination of certain Subaru warning lights or onboard diagnostic messages. You may also notice drivability issues stemming from overheating or inadequate oil pressure. Power loss, ominous noises and discolored fluids are other signs to book Subaru engine service in Nampa.
Typically, engines fail due to improper maintenance. Neglecting to perform routine Subaru oil changes or coolant flushes can damage internal engine parts relying on proper lubrication and cooling. Another factor can be potentially damaging habits such as regularly revving a cold engine to redline.
Engine failure can often be traced back to three causes: inadequate lubrication, ineffective cooling and detonation.
Lubrication. Lubrication issues typically stem from a lack of oil. Bearings — small metal sleeves used to enable smooth rotational movement between two internal engine parts — only work as intended when properly lubricated. Without enough oil, the parts make contact, and the resulting friction can cause quick failure.
Cooling. Coolant flows through the engine to keep important Subaru parts from overheating. Over time, coolant loses it potency as a temperature regulator. As engine temperatures rise, internal components are subjected to extreme mechanical stresses, and parts like the Subaru head gasket can fail.
Detonation. Detonation refers to when an engine isn’t igniting its air/fuel mixture at the appropriate time. If ignition occurs even a fraction of a second too soon or too late, the result is a less controlled burn that can spike pressure in the engine cylinders. Over time, the effects of this can lead to serious internal engine damage.
It’s important to remember that failures such as these are rare and often preventable — by simply following the recommended Subaru maintenance intervals outlined in your owner’s manual, you’ll dramatically reduce the likelihood of ever needing in-depth engine repairs.
