To Whom It May Concern at the National Highway Traffic Safety Administration (NHTSA), I am submitting this complaint regarding the Mercedes-Benz GLA-Class vehicles equipped with the M274 engine, which have been unfairly excluded from recent recall campaigns affecting this engine family. The same engine (M274) in other models — including the C-Class (C300), E-Class, and GLC-Class from the same model years — has been recalled due to serious issues affecting engine reliability and safety. The specific issue I (and many other GLA owners) have encountered is the activation of the Check Engine Light, accompanied by diagnostic trouble code P052E71, which refers to a malfunction in the crankcase ventilation valve. This is a well-documented failure associated with the M274 engine and has been a p

While driving on freeway around 70 MPH, the ip display just suddenly disappear for 1 split second, then the car shifted itself into neutral and displayed the following message: "transmission malfunction stop", then I coasted to the right shoulder area of the freeway, then I turned off the engine, waited for 1-2 minutes, then restarted the engine again without any issue. It happened 2 days in the row-one is yesterday afternoon; the other one this morning.

car engine turned off by itself in the traffic. It has happened a few times when I was waiting at the traffic light or waiting in lane to make turn. The engine suddenly turned off completely and I was caught in the traffic.

When turning, I hear a thumping, grinding or chatter noise from the rear differential and the car slows. Mechanic changed the differential oil and found metal shavings/particals. Noise was not there for about 80 miles but has returned. I have to get a new right differential. I checked on the forums and this seems to be a common problem, one owner has had to replace his differential 4 times.
