Engine

2.0L Turbocharged Inline-4 (M133)

• Excessive Oil Consumption
  • Description/Symptoms: Owners have reported higher than expected oil consumption, requiring frequent top-offs between oil changes. This can manifest as the “check engine oil level” warning appearing frequently.
  • Solution: Monitor oil levels regularly and address any leaks promptly. In some cases, a faulty PCV valve or worn piston rings may be the cause, requiring replacement.
  • Estimated Cost to Fix: $500 - $3,000+ depending on the cause (PCV valve vs. piston rings).
  • Recalls: None Found
• Turbocharger Failure
  • Description/Symptoms: Loss of power, unusual noises from the turbocharger (whining, screeching), and potential check engine light activation.
  • Solution: Turbocharger inspection and replacement if necessary.
  • Estimated Cost to Fix: $2,000 - $4,000+
  • Recalls: None Found
• Coolant Leaks
  • Description/Symptoms: Coolant levels dropping, overheating, visible coolant leaks under the vehicle, and potential check engine light activation.
  • Solution: Identify the source of the leak (water pump, hoses, radiator) and replace the faulty component.
  • Estimated Cost to Fix: $200 - $1,500+ depending on the source of the leak.
  • Recalls: None Found

Transmission

7-Speed AMG SPEEDSHIFT DCT (Dual-Clutch Transmission)

• Rough or Jerky Shifting
  • Description/Symptoms: Harsh or abrupt shifts, particularly at low speeds, or during gear changes while accelerating or decelerating.
  • Solution: Transmission fluid flush and adaptation reset may improve shifting quality. In some cases, valve body issues or clutch wear may require more extensive repairs.
  • Estimated Cost to Fix: $300 - $4,000+ depending on the issue (fluid flush vs. valve body replacement).
  • Recalls: None Found
• Transmission Slippage
  • Description/Symptoms: Engine revving without corresponding acceleration, delayed engagement of gears, or a feeling of the transmission slipping.
  • Solution: Inspect transmission fluid level and condition. If slippage persists, a transmission rebuild or replacement may be necessary.
  • Estimated Cost to Fix: $5,000 - $8,000+
  • Recalls: None Found

Suspension

• No Issues Found

Electrical

• Battery Drain Issues
  • Description/Symptoms: The car is hard to start or won’t start at all, especially after sitting for a few days. Repeatedly needing to jump-start the vehicle.
  • Solution: Diagnose parasitic draw by testing current draw while the car is off and pulling fuses. The common causes are the aftermarket installed alarms, other aftermarket accessories, or a faulty control module.
  • Estimated Cost to Fix: $150 - $1,000+ depending on the source of the draw.
  • Recalls: None Found
• Malfunctioning Sensors
  • Description/Symptoms: Check engine light activation, inaccurate readings from sensors (e.g., oxygen sensors, mass airflow sensor), and related performance issues.
  • Solution: Diagnose and replace the faulty sensor.
  • Estimated Cost to Fix: $100 - $500+ per sensor.
  • Recalls: None Found

Exterior

• No Issues Found

Interior

• Malfunctioning Infotainment System

  • Solution: Software updates may resolve some issues. In other cases, the head unit may need replacement.
  • Estimated Cost to Fix: $100 - $2,000+ (Software update vs. Head Unit Replacement).
  • Recalls: None Found
• Sunroof Issues
  • Description/Symptoms: Sunroof not opening or closing properly, making grinding noises, or leaking.
  • Solution: Inspection of the sunroof mechanism, track, and motor. Repair or replacement of damaged components.
  • Estimated Cost to Fix: $300 - $1,500+
  • Recalls: None Found
