Common Issues With The 2024 Subaru WRX

As of January 2025, the 2024 Subaru WRX has not been on the market long enough to accumulate a significant number of owner-reported issues. However, examining common problems from previous WRX models can provide insight into potential concerns. Here are some issues reported in earlier models that may be relevant:

Performance and Engine:

At the heart of the 2024 WRX is a 2.4-liter direct-injection turbocharged SUBARU BOXER® engine, delivering 271 horsepower and 258 lb-ft of torque. This power is managed through either a six-speed manual transmission or an available Subaru Performance Transmission (SPT) – a performance-tuned continuously variable transmission (CVT) that offers rapid upshifts and downshifts. The WRX’s renowned symmetrical all-wheel drive system ensures optimal traction and handling across various driving conditions.

Trim Levels:

The 2024 WRX is available in multiple trims to cater to diverse preferences:

• Base: Offers essential performance features and a driver-focused interior.
• Premium: Adds amenities like a larger infotainment display, enhanced audio system, and additional comfort features.
• Limited: Includes leather-trimmed upholstery, advanced driver-assistance systems, and premium interior accents.
• GT: Features electronically controlled dampers, Recaro® performance front seats, and exclusive exterior enhancements.
• TR: A new addition for 2024, the TR trim offers a tuned chassis for enhanced handling dynamics.
