What 2023 Mercedes-Benz GLB250 owners say

Engine & cooling

My 2023 Mercedes-Benz GLB 250 4MATIC, with approximately 70,000 miles, developed an intermittent Check Engine warning and began running rough and shaking during operation. The vehicle was taken to an authorized Mercedes-Benz dealership for diagnosis. The dealer confirmed a major engine problem and determined that the cylinder head assembly requires replacement. I am concerned that the failure of a major internal engine component on a vehicle of this age and mileage could create a safety risk, particularly because the vehicle was running rough and shaking while being driven and the Check Engine warning was intermittent. The vehicle is currently at the authorized Mercedes-Benz dealership and the cylinder head repair/replacement has begun. …

Sep 2026

My 2023 Mercedes-Benz GLB 250 is experiencing engine misfires and fault codes consistent with a known cylinder head defect that is the subject of a recall affecting 2022 and earlier models. A certified mechanic has confirmed the issue aligns with the recall defect. Despite identical symptoms and engine configuration, my VIN is excluded. The condition results in loss of power and creates a potential safety hazard while driving. The following codes are referenced in the Mercedes recall and by recorded by the auto repair shop that provided an estimate for the repair: P1CEF85 - Injector injection quantity adjustment for cylinder balancing has almost reached the upper limit value at atleast one cylinder. P1CE577 - Injector injection quantity adjustment for uniform mixture formation has detected an excessively lean mixture at atleast one cylinder.
