What owners reported
2023 Mercedes-Benz GLB owner complaints in detail
Owner complaints3
POWER TRAIN
Owners of the 2023 Mercedes-Benz GLB report issues primarily related to transmission and power loss. Complaints frequently mention the vehicle losing motive power, with the transmission warning light illuminating in some instances. Symptoms include abnormal shuddering while driving and engine misfires associated with fault codes similar to a known cylinder head defect from earlier models, though this specific model year is not covered by the recall. These issues are reported at mileages ranging from approximately 3,200 to 18,000 miles. Safety implications are noted, as the loss of power and malfunctioning brakes could pose hazards while driving.
Owner complaints3
ENGINE
Owners report recurring engine issues with the 2023 Mercedes-Benz GLB, primarily involving cylinder head problems and misfires. Complaints frequently mention irregular mixture formation and fuel injector issues, with one owner noting a diagnostic code P219F related to Cylinder 4. Symptoms include the vehicle failing to accelerate, which poses a safety risk as noted by an owner who was nearly involved in collisions. Another owner reports extensive engine repairs, including a complete rebuild within two years of ownership. These issues often emerge around or after 55,000 miles, with some repairs not covered by Mercedes-Benz despite being recognized by dealerships as known problems.
Owner complaints2
UNKNOWN OR OTHER
Owners of the 2023 Mercedes-Benz GLB report two significant issues under the unknown or other category. One complaint describes the transmission unexpectedly shifting to neutral while driving on the highway, with incidents occurring twice in December 2024, which could imply potential safety risks due to loss of propulsion. Another issue involves the front stationary roof panel cracking, which exposes windshield components to weather elements, such as rain. This complaint also references similar reports across various Mercedes-Benz models and years, and mentions the high cost of repair at over $2000. These issues suggest potential safety implications and financial considerations for prospective buyers.
