Common Problems and Solutions for the 2017 Subaru Legacy 3.6R Limited
Engine and Powertrain Concerns
One of the most reported concerns with the 2017 Subaru Legacy 3.6R Limited revolves around its engine. Although the 3.6R engine is generally robust, a few issues have popped up. Oil consumption is a notable problem. Some owners have reported that the engine burns oil between oil changes. This isn't just an inconvenience; it can lead to engine damage if left unchecked. You'll want to regularly check your oil level, maybe even every fuel fill-up, and top it off as needed. If the oil consumption is excessive, it's a good idea to consult with a mechanic. They can perform diagnostic tests to determine the cause, which could range from worn piston rings to valve stem seals. The solutions can vary; in some cases, a simple oil change with a heavier-weight oil might help, while in others, more significant repairs might be necessary.
Another issue that sometimes crops up is related to the engine misfires. Misfires can be caused by various things, like faulty spark plugs, ignition coils, or even fuel injector problems. The symptoms usually include a rough idle, reduced power, and the check engine light flashing. If you experience these symptoms, it's crucial to get the car diagnosed as soon as possible. Ignoring misfires can lead to more severe damage to the engine, including catalytic converter failure. A mechanic can use an OBD-II scanner to identify the cylinder(s) misfiring and then perform the necessary repairs. Replacing the spark plugs and ignition coils is a common fix, and it's generally not too expensive. However, if the fuel injectors are the problem, it might be a bit more costly. Regular maintenance, such as replacing the spark plugs at the recommended intervals, can help prevent these issues.
Finally, some owners have mentioned concerns about minor leaks. These can occur from various seals and gaskets in the engine. While a small leak might not be immediately detrimental, it's always best to address them promptly to prevent further issues. Keeping an eye on the engine for oil stains and monitoring fluid levels can help catch these leaks early on. If you notice a leak, a mechanic can inspect the engine and replace the faulty seals or gaskets. Ignoring these leaks could lead to lower oil levels and potential engine damage. Addressing these issues in a timely manner will keep your Legacy running smoothly for years to come.
Transmission Issues
Although the 2017 Subaru Legacy 3.6R Limited is known for its smooth CVT transmission, some owners have reported transmission-related problems. One common complaint is transmission shudder. This can feel like a vibration or shaking, especially when accelerating or decelerating. The causes for this can range, from torque converter issues to problems with the transmission fluid. The best course of action is to have a mechanic inspect the transmission. They can check the fluid level and condition, and perform diagnostic tests to pinpoint the problem. In some cases, a transmission fluid flush and replacement might resolve the issue. If the torque converter is the problem, it might need to be replaced, which can be a more costly repair. To prevent these issues, it's important to follow the recommended transmission fluid change intervals outlined in your owner's manual. Doing so can prolong the life of your transmission and prevent expensive repairs.
Another possible concern is transmission slippage. Slippage can manifest as the engine revving higher than usual without a corresponding increase in speed. This can happen under acceleration or when climbing hills. If you notice this, it's a sign that the transmission might not be engaging the gears correctly. This could be due to low transmission fluid, worn clutches, or other internal problems. Again, it’s best to have a mechanic diagnose the issue. They can check the fluid level and condition and perform a transmission pressure test. Depending on the diagnosis, the mechanic might recommend a fluid change, repairs, or even a complete transmission overhaul or replacement. Early detection and prompt repair can save you a lot of trouble down the line.
Electrical and Infotainment System Issues
Electrical and infotainment system problems can be a source of frustration for owners. Infotainment system glitches are among the most common complaints. The 2017 Legacy 3.6R Limited has a touchscreen infotainment system, and some owners have reported issues like freezing screens, slow response times, and system crashes. These problems can range from a minor annoyance to a more significant problem that affects the functionality of the system, including navigation, audio, and climate controls. The first troubleshooting step is often a system reset. This might involve holding down the power button or disconnecting the car's battery for a few minutes. If a reset doesn't work, there might be a software update available from Subaru that addresses these issues. Your dealer can install these updates. In some cases, the infotainment system might need to be replaced if the problems persist. Regular software updates are crucial for ensuring the system runs smoothly and for fixing any known bugs.
Electrical issues such as faulty sensors or wiring problems can also occur. For instance, some owners have reported issues with the backup camera or the power windows. These problems can be frustrating, especially if they affect safety features. If you experience these kinds of problems, the best course of action is to get the car diagnosed by a mechanic who specializes in electrical systems. They can use diagnostic tools to identify the faulty component or wiring problem. Depending on the issue, the solution could range from replacing a sensor to repairing or replacing wiring. Regular maintenance and inspections can help catch these issues before they become major problems. Also, ensure that all the fuses are in good condition and are of the correct amperage, as this is a very common cause of minor electrical problems.
Body and Exterior Problems
While the 2017 Subaru Legacy 3.6R Limited is generally well-built, there are some potential body and exterior problems to be aware of. One common issue is rust. Subaru is known for its rust resistance, but like any car, it can be susceptible to rust, especially in areas with harsh winters and road salt. Pay close attention to the undercarriage, wheel wells, and other areas where rust is likely to form. Regularly washing and waxing the car can help protect against rust. Also, if you notice any signs of rust, address them promptly. A good body shop can remove the rust, repair the damage, and apply rust protection coatings. Ignoring rust can lead to more extensive and expensive repairs later on.
Paint problems such as chipping, fading, or peeling are another area of concern. The quality of the paint can vary, and environmental factors like sun exposure and harsh weather can accelerate the wear. If you notice any paint problems, it's best to address them as soon as possible to prevent further damage. Regularly washing and waxing the car will help protect the paint. You can also use a paint sealant or ceramic coating for added protection. If the paint is chipped or scratched, touch-up paint can help prevent rust. More extensive paint damage might require professional repair.
Other Potential Issues
Beyond the more common issues mentioned above, there are a few other potential problems that might occur with the 2017 Subaru Legacy 3.6R Limited. Brake problems are a possibility, as with any car. You should be aware of this, especially if you notice unusual noises, vibrations, or a spongy brake pedal. Regularly inspecting the brake pads, rotors, and calipers is essential. Following the recommended brake maintenance schedule can prevent more severe brake problems. Addressing brake problems early on can help maintain your safety on the road.
Suspension problems can also occur. These can manifest as unusual noises, a rough ride, or uneven tire wear. If you notice any of these symptoms, it's a good idea to have the suspension checked. A mechanic can inspect the shocks, struts, springs, and other components. Regular inspections and timely repairs can help maintain the handling and ride quality of your Legacy.
