Subaru WRX Common Problems

ENGINE

Owners report that the 2022 Subaru WRX frequently experiences issues with excessive RTV sealant in the engine, particularly around the oil pan. This sealant can break off and clog the oil pickup, leading to oil starvation and potential engine failure. Complaints often describe symptoms such as a burning smell from the engine bay and, in some cases, complete engine failure under 4,000 miles. There are no reports of crashes directly linked to this issue, but the potential for engine failure while driving poses a safety risk. Used car buyers should be aware of these reports, especially since addressing the issue may require significant labor to remove and clean the RTV from the engine.

ELECTRICAL SYSTEM

Owners report frequent issues with battery drainage in the 2019 Subaru WRX, often linked to the telematics system and parasitic drain. Complaints commonly describe dead batteries after short periods of inactivity, with some vehicles failing to start after being left idle for just a day. Multiple owners mention experiencing these problems even with low mileage, such as under 20,000 miles. Additionally, there are reports of the vehicle shutting down momentarily during operation, causing temporary loss of steering control, which poses a safety risk. These patterns suggest potential reliability concerns for used car buyers considering this model.

ELECTRICAL SYSTEM

Owners of the 2018 Subaru WRX frequently report issues with battery drainage, with multiple complaints describing the vehicle becoming inoperable after short periods of non-use or shortly after being turned off. Symptoms include the vehicle failing to start, requiring frequent battery replacements, and needing jumps to restart. These issues appear across a wide range of mileages, from as low as 5,000 miles to higher mileages like 96,000 miles. Additionally, one owner mentions a problem with the vehicle incorrectly indicating reverse gear while driving forward, activating the backup camera and reverse lights. Safety implications include the risk of being stranded in unsafe locations and potential hazards from unexpected vehicle behavior.

ENGINE

Owners report frequent engine failures in the 2018 Subaru WRX, primarily due to rod bearing issues. Typical symptoms include engine knocking, sudden loss of power, and in some cases, complete engine failure, often occurring around 32,000 to 67,000 miles. Additional complaints describe a strong fuel odor linked to a high-pressure fuel pipe leak, posing a potential fire hazard. Safety implications include risks of being stranded and loss of vehicle control. Buyers should be aware that these issues may require significant repairs or replacements, even at relatively low mileage.

STEERING

Owners of the 2018 Subaru WRX frequently report steering issues, with several complaints describing instances where the steering wheel locks up, often leading to a loss of control. These incidents typically occur during turns or while driving at moderate speeds, with some reports indicating the problem may be linked to the vehicle's safety systems activating unexpectedly. Complaints often involve crashes, and two reports mention injuries, suggesting significant safety implications. The issues are noted at various mileage points, with some vehicles having as few as 1,055 miles. Buyers should be aware of these reported steering malfunctions and the potential for accidents when considering a used 2018 Subaru WRX.

UNKNOWN OR OTHER

Owners report that the 2024 Subaru WRX's infotainment system displays full-screen SiriusXM advertisements while driving, taking over the entire screen and requiring manual dismissal to regain access to controls. Complaints frequently mention that this occurs at various speeds and in different driving conditions, posing a distraction by diverting attention from the road. Multiple owners describe being unable to access crucial functions like navigation and climate control until the ad is closed. There are no reports of crashes or injuries, but the sudden appearance of these ads is described as a significant distraction, particularly in adverse weather or high-traffic situations. Buyers should be aware of this issue, as it could impact driving focus and access to vehicle controls.

POWER TRAIN

Owners of the 2021 Subaru WRX frequently report powertrain issues, particularly involving engine and transmission failures. Complaints often describe severe engine damage, with symptoms such as knocking noises, increased engine oil temperature, and stalling, typically occurring around 38,000 miles. Transmission problems include binding, refusal to accelerate, and surging RPMs, with some reports occurring as early as 10,510 miles. Several owners also mention warranty disputes, particularly when modifications like cold air intakes are present. Safety implications are noted, with some owners narrowly avoiding collisions due to sudden loss of power or control. Potential buyers should be aware of these issues, especially given the reports of significant repair costs and prolonged dealership visits.
