10 Top Mechanical and Electrical Issues

1. Turbocharger Carbon Buildup & Boost Loss (Si/Type R)

Symptoms:

• Reduced turbo boost pressure and horsepower
• Hesitation or lag during acceleration
• Check engine light (P0101, P0102 codes)
• Black soot around turbo intake
• Increased fuel consumption

Root Cause: Direct fuel injection deposits carbon on intake valves over time. Poor quality fuel and extended oil change intervals accelerate this. Turbocharger waste gate sticks from carbon accumulation, reducing boost efficiency.

Fix:

• Perform walnut shell blasting to clean intake valves (remove cylinder head)
• Replace fuel injectors with OEM units if completely clogged
• Clean turbocharger compressor wheel and waste gate
• Use fuel system cleaner additives between services
• Reduce oil change intervals to 5,000 miles

Cost: $800–$1,500 (cleaning); $2,000–$3,000 (if injectors replacement needed)

2. CVT Transmission Juddering & Hesitation

Symptoms:

• Jerky acceleration or gear selection delay
