Engine

5.0L Twin-Turbo V10

• Oil Leaks
  • Description/Symptoms: Oil leaks can occur from various points on the engine, including valve cover gaskets, oil cooler lines, and the rear main seal. Symptoms include visible oil drips, burning oil smell, and low oil level warnings.
  • Solution: Replace the leaking gaskets or seals. Inspect and replace damaged oil cooler lines.
  • Estimated Cost to Fix: $200 - $2,000+ depending on the location and severity of the leak.
• Carbon Buildup
  • Description/Symptoms: Direct injection engines like the V10 are prone to carbon buildup on the intake valves, leading to reduced performance, rough idling, and misfires.
  • Solution: Perform a carbon cleaning service, such as walnut blasting, to remove the buildup.
  • Estimated Cost to Fix: $800 - $1500+
• Ignition Coils Failure
  • Description/Symptoms: Misfires, rough running, and a check engine light are common symptoms. Often, specific cylinder misfire codes will be present.
  • Solution: Replace faulty ignition coils. It’s recommended to replace all ignition coils at the same time to avoid repeat failures.
  • Estimated Cost to Fix: $50 - $200 per coil, $50 - $200 for labor.

Transmission

6-Speed Automatic

• Torque Converter Failure
  • Description/Symptoms: Shuddering during gear changes, slipping, or complete transmission failure.
  • Solution: Replace the torque converter. In severe cases, a complete transmission rebuild or replacement may be necessary.
  • Estimated Cost to Fix: $1,500 - $5,000+ depending on the extent of the damage.
• Mechatronic Unit Failure
