Head Gaskets:
While less prevalent than in earlier generations, EJ25 engines can still be susceptible to head gasket failure, especially with neglect or overheating. Early detection is key.
Automatic Transmission Issues:
Some reports of hesitation or slipping in older 4EAT transmissions, often related to fluid degradation or valve body issues. Regular fluid changes are critical.
Oil Leaks:
Valve cover gaskets and oil pan gaskets can degrade over time, leading to leaks.
Suspension Wear:
Control arm bushings and sway bar links can wear out, leading to clunking noises and poor handling.
Turbocharger Failure Gt Models:
Turbocharger can fail if oil supply is restricted or if the engine is overheated. Proper maintenance and warm-up/cool-down procedures are important.
