• Timing Chain Tensioner Failure
  • Description/Symptoms: Rattling noise upon startup, especially in colder weather. This is caused by a faulty timing chain tensioner that allows the chain to slack, leading to the noise. Over time, if the tensioner continues to fail, it can cause significant engine damage and potential timing chain failure.
  • Solution: Replace the timing chain tensioner, guides, and chain.
  • Estimated Cost to Fix: $1,500 - $2,500+
  • Recalls: None Found
• Oil Consumption
  • Description/Symptoms: Some owners have reported excessive oil consumption. Symptoms include the need to frequently add oil between oil changes and blue exhaust smoke, potentially indicating worn piston rings or valve stem seals.
  • Solution: The problem can range from needing to replace PCV valve to a full engine rebuild.
  • Estimated Cost to Fix: $50 - $5,000+
  • Recalls: None Found

Transmission

7-Speed Automatic (RE7R01A)

• Valve Body Issues
  • Description/Symptoms: Harsh or delayed shifting, especially between certain gears. Slipping can occur. The issue is caused by worn or malfunctioning valves within the transmission valve body, which controls hydraulic pressure to the various clutches and brakes in the transmission.
  • Solution: Replacement of the valve body. Sometimes, a complete transmission rebuild is necessary.
  • Estimated Cost to Fix: $800 - $4,000+
  • Recalls: None Found

Suspension

• Strut/Shock Failure
  • Description/Symptoms: Bumpy ride, excessive bouncing, clunking noises over bumps, poor handling. Struts/shocks lose their damping ability over time, leading to these symptoms.

  • Estimated Cost to Fix: $400 - $1,200+
  • Recalls: None Found

Electrical

• Battery Drain
  • Description/Symptoms: The vehicle has difficulty starting or a dead battery, particularly after sitting for a period of time. This can be caused by a parasitic draw from a faulty module or accessory that is not shutting down properly.
  • Solution: Locate and repair the source of the parasitic draw. Common culprits include aftermarket accessories (e.g., alarms, remote starters), the navigation system, or the Bluetooth module.
  • Estimated Cost to Fix: $100 - $800+ depending on the component.
  • Recalls: None Found
• Navigation Screen Failure
  • Description/Symptoms: The navigation screen may flicker, go blank, or become unresponsive. This can be due to a failure of the LCD screen, the video processing module, or the wiring harness connecting these components.
