2024 Mercedes-Benz GLB250

The 2024 Mercedes-Benz GLB250 is a compact SUV that offers a blend of practicality and luxury. It comes standard with a 2.0-liter inline-4 turbocharged engine producing 221 horsepower and 258 lb-ft of torque, paired with an 8-speed dual-clutch automatic transmission. An AMG version, the GLB35, offers a more powerful engine. People generally appreciate the GLB250 for its spacious interior, especially the available third-row seating (though cramped), its upscale cabin, and its comfortable ride. Common complaints include the sometimes-hesitant transmission, the relatively high price for the segment, and the somewhat underwhelming fuel economy compared to competitors.

Engine

2.0-Liter Inline-4 Turbocharged

• Excessive Oil Consumption
  • Description/Symptoms: Some owners have reported higher-than-expected oil consumption, requiring more frequent oil top-offs between scheduled oil changes. Symptoms include low oil level warnings and potentially engine knocking or damage if the oil level is allowed to get too low.
  • Solution: Monitor oil levels regularly. Consult a Mercedes-Benz dealership for diagnosis and potential repair. This may involve replacing the PCV valve or piston rings if consumption is excessive.
  • Estimated Cost to Fix: $500-$5,000+ depending on the severity and the required repair (PCV valve replacement is less expensive, piston ring replacement is significantly more).
