Subarus have a reputation for being reliable vehicles, and for good reason. From their all-wheel-drive systems to their durable engines, Subarus are known for their longevity and dependability. In this article, we’ll explore what makes Subarus reliable, as well as some of the common problems that can make a Subaru unreliable.
Why are Subarus Reliable?
One of the main reasons Subarus are so reliable is their all-wheel-drive system. This system is designed to provide excellent traction and stability, even in challenging road conditions. The system also distributes power to all four wheels, which helps reduce wear and tear on individual components.
Subarus are also known for their durable engines. Many Subaru models feature boxer engines, which are designed to be low-profile and more efficient than traditional engines. These engines are known for their long lifespans and are often still running strong with over 200,000 miles on the odometer.
Common Problems that can Make a Subaru Unreliable
Head Gasket Failure
One of the most common problems that can make a Subaru unreliable is head gasket failure. This problem can occur in both the 2.5L and 2.0L engines, and is often caused by a combination of overheating and coolant leaks. Symptoms of head gasket failure can include overheating, white smoke from the exhaust, and coolant loss. To address this issue, the head gasket will need to be replaced, which is a time-consuming and expensive repair.
Oil Consumption
Another common problem that can make a Subaru unreliable is excessive oil consumption. This problem can occur in both newer and older Subaru models, and is often caused by worn piston rings or valve seals. Symptoms of excessive oil consumption can include low oil levels between oil changes, blue smoke from the exhaust, and engine knocking. To address this issue, the worn piston rings or valve seals will need to be replaced.
CV Joint Failure
CV joint failure is another problem that can make a Subaru unreliable. The CV joint is responsible for transferring power from the transmission to the wheels, and can wear out over time. Symptoms of CV joint failure can include clicking or popping noises when turning, vibration during acceleration, and reduced handling or stability. To address this issue, the CV joint will need to be replaced, which can be a relatively simple and inexpensive repair.
Timing Belt Failure
Timing belt failure is another common problem that can make a Subaru unreliable. The timing belt is responsible for keeping the engine’s valves and pistons in sync, and can wear out over time. Symptoms of timing belt failure can include rough idling, engine misfires, and difficulty starting the engine. To address this issue, the timing belt will need to be replaced, which is a relatively simple but time-consuming repair.
Transmission Failure
Finally, transmission failure is another problem that can make a Subaru unreliable. This problem can occur in both manual and automatic transmissions, and is often caused by wear and tear over time. Symptoms of transmission failure can include slipping gears, rough shifting, and transmission fluid leaks. To address this issue, the transmission will need to be repaired or replaced, which can be a costly repair.
