Engine

2.0L Turbocharged Inline-4 (BPY)

• Cam Follower Failure
  • Description/Symptoms: Ticking noise from the engine, rough idle, loss of power, and eventually, complete fuel pump failure. This happens when the cam follower wears through, damaging the camshaft lobe.
  • Solution: Replace the cam follower regularly, or convert to a roller bearing follower. If damage to the camshaft has occurred, the camshaft must also be replaced.
  • Estimated Cost to Fix: $100 - $500+ depending on camshaft damage and labor.
  • Recalls: None Found
• Diverter Valve Failure
  • Description/Symptoms: Loss of boost, decreased fuel economy, and possible check engine light. The diverter valve recirculates excess boost pressure back into the intake system.
  • Solution: Replace the diverter valve with an updated version (revision D is a common upgrade) or aftermarket performance diverter valve.
  • Estimated Cost to Fix: $75 - $200+
  • Recalls: None Found
• Oil Leaks
  • Description/Symptoms: Oil drips under the car, burning oil smell, low oil level. Common leak points include the valve cover gasket, rear main seal, and timing chain tensioner.
  • Solution: Replace the leaking gasket or seal.
  • Estimated Cost to Fix: $100 - $800+ depending on the location of the leak.
  • Recalls: None Found

3.6L VR6

• Timing Chain Issues
  • Description/Symptoms: Rattling noise on startup, especially when cold. In severe cases, the engine may run poorly or not start at all. This issue is typically caused by worn timing chain guides and tensioners.
  • Solution: Replace the timing chains, guides, and tensioners.
  • Estimated Cost to Fix: $1,500 - $3,000+
  • Recalls: None Found
• Intake Manifold Runner Control (IMRC) Failure
  • Description/Symptoms: Check engine light, reduced engine performance, and poor fuel economy. The IMRC system controls airflow into the engine.
  • Solution: Replace the faulty IMRC unit.
  • Estimated Cost to Fix: $500 - $1,000+
  • Recalls: None Found

Transmission

6-Speed Automatic (Aisin)

• Valve Body Issues
  • Description/Symptoms: Harsh or delayed shifting, slipping between gears, and possible limp mode. The valve body controls the flow of transmission fluid to the various components.
  • Solution: Replace or rebuild the valve body. In some cases, a software update may help.
  • Estimated Cost to Fix: $800 - $2,000+
  • Recalls: None Found

Suspension

• Front Control Arm Bushing Failure
  • Description/Symptoms: Clunking noise from the front suspension, especially when going over bumps. Poor handling and tire wear may also be noticeable.
  • Solution: Replace the worn control arm bushings or the entire control arm assembly.
  • Estimated Cost to Fix: $200 - $600+ per side
  • Recalls: None Found

Electrical

• Door Lock Actuator Failure
