• Excessive Oil Consumption
  • Description/Symptoms: Some owners have reported higher than normal oil consumption requiring frequent top-offs between scheduled oil changes. Symptoms may include the low oil level warning light illuminating, noticeable oil smell, or the need to add oil more frequently than expected.
  • Solution: The solution can range from simply monitoring oil levels and topping off as needed to more involved repairs like piston ring replacement in severe cases. A dealer performed oil consumption test is usually required to determine the root cause.
  • Estimated Cost to Fix: Varies widely depending on the cause. Monitoring and topping off oil has minimal cost. Piston ring replacement can range from $5,000 - $8,000+ depending on the dealer.

• Harsh or Jerky Shifting
  • Description/Symptoms: Some owners have reported experiencing harsh or jerky shifts, particularly at lower speeds or during downshifts. This can manifest as a noticeable “clunk” or hesitation during gear changes.
  • Solution: Some instances are improved with a software update to the Transmission Control Module (TCM) or a transmission fluid flush/service. In more severe cases, valve body replacement or complete transmission replacement may be required.
  • Estimated Cost to Fix: Software updates are typically covered under warranty. Transmission fluid flush/service may cost around $500. Valve body replacement can range from $2,000 - $4,000. Transmission replacement can range from $8,000 - $12,000.

Suspension

• Stiff Ride Quality
  • Description/Symptoms: The CLA45 AMG is known for its sporty but firm suspension. Some owners have complained that the ride quality is too harsh for daily driving, particularly on rough roads. This can lead to discomfort for both the driver and passengers.
  • Solution: Unfortunately, the suspension is part of the package on the CLA45 AMG. There are no specific solutions to soften the ride without sacrificing the performance characteristics of the vehicle. Some owners may consider aftermarket adjustable dampers, but this can affect handling.
  • Estimated Cost to Fix: N/A, it is not a defect. Replacing shocks with aftermarket adjustable shocks will depend on the brand of shocks and can range from $2,000 - $4,000+
