Engine

4.0L Twin-Turbocharged V8

• Turbocharger Failure
  • Description/Symptoms: Owners report experiencing a loss of power, unusual noises (whining or whistling) from the engine bay, and/or the check engine light illuminating. Diagnostic codes often point to issues with the turbochargers or associated wastegate systems. This failure has been reported to occur at varying mileage, sometimes even relatively early in the vehicle’s life.
  • Solution: Diagnosis involves inspecting the turbochargers for physical damage, checking for leaks in the boost system, and verifying the functionality of the wastegates. Replacement of the affected turbocharger(s) is typically required.
  • Estimated Cost to Fix: $4,000 - $8,000+ (depending on whether one or both turbos need replacing and labor rates).
  • Recalls: None Found
• Oil Leaks
  • Description/Symptoms: Oil leaks can develop from various locations on the engine, including the valve cover gaskets, rear main seal, and oil cooler lines. Symptoms include visible oil drips on the ground, a burning oil smell, and low oil levels.
  • Solution: Identify the source of the leak and replace the affected gasket or seal.
  • Estimated Cost to Fix: $200 - $2,000+ depending on the location and severity of the leak.
  • Recalls: None Found
• Coolant Leaks
  • Description/Symptoms: Owners have reported coolant leaks. This could be either an internal or external leak, where the coolant may not be visible. If coolant is leaking internally, there may be coolant present in the oil or exhaust.
  • Solution: Find the source of the leak and repair/replace the damaged components.
  • Estimated Cost to Fix: $200 - $2,000+ depending on the location and severity of the leak.
  • Recalls: None Found

Transmission

8-Speed Automatic Transmission

• Rough Shifting/Hesitation
  • Description/Symptoms: Some owners have reported experiencing rough or delayed shifting, particularly between lower gears. There may also be hesitation or a noticeable “thunk” when shifting.
  • Solution: In some cases, a transmission software update can resolve the issue. If the problem persists, a more thorough inspection of the transmission valve body and clutch packs may be necessary, potentially leading to replacement of faulty components.
  • Estimated Cost to Fix: $150 for a software update, $1,000 - $4,000+ for valve body/clutch pack repair or replacement.
  • Recalls: None Found
• Torque Converter Issues
  • Description/Symptoms: Humming, shaking, and/or the car failing to accelerate properly.
  • Solution: Replace the torque converter.
  • Estimated Cost to Fix: $1,500 - $3,000+
  • Recalls: None Found

Suspension

• Air Suspension Compressor Failure
  • Description/Symptoms: The air suspension system may fail, leading to the vehicle sitting unevenly, a harsh ride, or the inability to adjust the ride height. A warning light on the dashboard is also common. This is often caused by a failing air suspension compressor.
  • Solution: Replacement of the air suspension compressor. It’s also important to check for leaks in the air struts themselves, as compressor failure can be caused by overworking due to a leaking strut.
  • Estimated Cost to Fix: $1,000 - $2,500+ (including compressor and potentially strut replacement).
  • Recalls: None Found
• Air Strut Failure
  • Description/Symptoms: Vehicle is sagging on one side, excessive bounce in the suspension, or air hissing.
  • Solution: Replace the affected air strut.
  • Estimated Cost to Fix: $1,000-$2,000+ per strut.
  • Recalls: None Found

Electrical

• Infotainment System Glitches
  • Description/Symptoms: The MMI (Multi Media Interface) system can experience freezing, lagging, or random reboots. Connectivity issues with Bluetooth or Apple CarPlay/Android Auto are also reported.
  • Solution: A software update may resolve the issue. In more severe cases, the MMI unit may need to be replaced.
  • Estimated Cost to Fix: $150 for a software update, $1,000 - $3,000+ for MMI unit replacement.
  • Recalls: None Found
• Sensor Malfunctions
  • Description/Symptoms: Issues can arise with various sensors, including parking sensors, blind-spot monitoring sensors, and adaptive cruise control sensors. These malfunctions can trigger warning lights and affect the functionality of the associated systems.
  • Solution: Diagnosis involves scanning the vehicle’s computer for error codes and testing the sensors. Replacement of the faulty sensor is typically required.
  • Estimated Cost to Fix: $200 - $800+ per sensor (depending on the sensor and location).
  • Recalls: None Found
• Battery Drain
  • Description/Symptoms: Some owners report excessive battery drain, especially if the vehicle sits for extended periods. This can result in difficulty starting the car or a completely dead battery.
  • Solution: Diagnosis involves checking the battery’s condition and testing for parasitic draws. Potential causes include a faulty module not shutting down properly or an aftermarket accessory drawing power.
  • Estimated Cost to Fix: $200 - $500+ for battery replacement; additional cost for diagnosing and repairing parasitic drains.
  • Recalls: None Found

Exterior

• Headlight Issues
