2023 Mercedes-Benz GLA35 AMG

The 2023 Mercedes-Benz GLA35 AMG is a compact performance SUV that combines sporty driving dynamics with everyday practicality. It’s powered by a turbocharged 2.0-liter four-cylinder engine producing 302 horsepower and 295 lb-ft of torque, paired with an 8-speed dual-clutch automatic transmission. There are no other engine or transmission options available for the GLA35 AMG model. Owners generally appreciate the vehicle’s agile handling, quick acceleration, and stylish interior, but some dislike the firm ride and occasionally complex infotainment system.

Engine

2.0L Turbocharged Inline-4 (M260)

• Excessive Oil Consumption
  • Description/Symptoms: Some owners have reported higher-than-expected oil consumption, requiring more frequent oil top-offs between service intervals. This may be indicated by the low oil level warning light.
  • Solution: The issue is often difficult to diagnose definitively. Sometimes the PCV valve needs replaced as a starting point. An oil consumption test, performed by a Mercedes-Benz dealer, is often necessary to determine the extent of the problem. In severe cases, engine component replacement may be required.
  • Estimated Cost to Fix: Varies widely from the cost of a PCV valve replacement to thousands for internal engine repair.
  • Recalls: None Found
• Turbocharger Issues
  • Description/Symptoms: Some owners have reported failures of the turbocharger’s wastegate actuator. This can result in reduced engine performance, a check engine light, and diagnostic trouble codes related to turbocharger boost control.
  • Solution: Replacement of the wastegate actuator or the entire turbocharger assembly.
  • Estimated Cost to Fix: $1,500 - $3,000+
  • Recalls: None Found

Transmission

8-Speed Dual-Clutch Automatic (DCT)

• Rough or Jerky Shifting
  • Description/Symptoms: Some owners experience harsh or jerky shifting, especially at lower speeds or during cold starts. This can manifest as hesitation, clunking noises, or an overall lack of smoothness.
  • Solution: A software update might resolve the issue in some cases. If the problem persists, a transmission fluid flush or valve body replacement may be necessary. In extreme cases, a full transmission replacement might be required.
  • Estimated Cost to Fix: $200 (for fluid flush) to $6,000+ (for replacement).
  • Recalls: None Found

Suspension

• Premature Wear of Suspension Components
  • Description/Symptoms: Some owners have reported premature wear or failure of suspension components like bushings, ball joints, and struts/shocks. This can lead to clunking noises, reduced handling performance, and uneven tire wear.
  • Solution: Replacement of the worn or damaged suspension components.
  • Estimated Cost to Fix: $300 - $1,500+ depending on the part and labor.
  • Recalls: None Found

Electrical

• Infotainment System Glitches
  • Description/Symptoms: The MBUX infotainment system can experience various glitches, including freezing, lagging, spontaneous reboots, and connectivity issues with Apple CarPlay or Android Auto.
  • Solution: Software updates are the primary solution. If the problem persists, a system reset or, in rare cases, hardware replacement may be required.
  • Estimated Cost to Fix: Relatively low if only software issues. More for new hardware, but should be under warranty.
  • Recalls: None Found
• Sensor Malfunctions
  • Description/Symptoms: Various sensors, such as parking sensors, blind-spot monitoring sensors, and rain sensors, have been reported to malfunction. This can result in inaccurate readings, false alarms, or complete system inoperability.
  • Solution: Diagnosis and replacement of the faulty sensor.
  • Estimated Cost to Fix: $200 - $800+ depending on the sensor location and complexity.
  • Recalls: None Found

Exterior

• No Issues Found

Interior

• Rattling and Squeaking Noises
  • Description/Symptoms: Some owners have reported various rattling and squeaking noises emanating from the interior, particularly from the dashboard, door panels, and seats. These noises can be distracting and detract from the overall driving experience.
  • Solution: Locating and securing the source of the noise. This might involve tightening fasteners, applying sound-deadening material, or replacing worn clips or components.
  • Estimated Cost to Fix: Highly variable depending on the source of the noise.
  • Recalls: None Found

Summary

The 2023 Mercedes-Benz GLA35 AMG, while offering an engaging driving experience, may be susceptible to a few common issues. Engine problems, particularly concerning oil consumption and turbocharger components, can be costly to repair. Transmission smoothness and electrical gremlins within the infotainment system are also potential areas of concern. Suspension wear and interior noises are other potential issues. The severity and cost of these issues range from relatively minor software glitches to potentially expensive engine or transmission repairs. Prospective buyers should be aware of these potential problems and carefully inspect the vehicle’s service history and condition before making a purchase.
