When coming to a full stop at a red light (or any need to idle at a stop), the car frequently begins to hesitate as if it is about to cut off. I assume it has something to do with the ‘fuel saving feature’ which comes on in the form of a green symbol in the lower left of the odometer display (the engine is still running the AC) . When you start to drive again the car always jerks before moving , on at least 3 occasions it has actually cut off completely and must be restarted (everything goes off) - it is big problem, especially in heavy traffic (horns blaring & angry drivers are encountered) I almost had a car hit me from behind; my car had jerked slightly when I began to accelerate and then shut off completely. It is definitely a dangerous defect. The Dealership emphasizes 93 Octane gas or higher to help with this issue- but I Always use the highest Octane gas I can find ! It has happened VERY often - I dread stopping at red lights and stop signs, one day it will cause an accident.

Good Afternoon, the status of my vehicle is simply UNKNOWN. I purchased my vehicle on the 26th last year of January. That same day I drove it back home my car was jerking. So I went back the following day to see if I could get into another vehicle because this one was malfunctioning they didn’t want to do anything for me. I tried so many different options to get out of this car I had a few scares driving this car the week of ownership. About sis times my car cut off completely during traffic and I have some recorded videos. Theirs a leakage somewhere I can fill up my gas tank to full and drive maybe two blocks away from my house and the gas meter is say that I have half a tank. Now my car is overheating, it’s not cranking it just tells me on the dashboard that 4MATIC is unavailable.

Rear differential has failed/malfunctioned. The vehicle is available upon request. It is a road safety issue as it will stall/ hesitate when accelerating and has a jerking effect. It has been confirmed by an independent service center. It had not been inspected by anyone, other than an independent service center mechanic. There were no warning lamps, messages or other symptoms of the problem prior to the failure.

My Car's warranty expired in Dec 2022 and a few months later the engine light came on. It stayed on for a few weeks than was turned off by itself. In Dec 2023, the engine light came back on again. I also noted jerks when driving slow (10 miles/h). Upon checking with Mercedes Benz of Tri Cities-Richland, WA, spending $400 on diagnostics, the staff quoted me $3500 for Crank Case Ventilation replacement. This is a really expensive part/labor and it is ridiculous that Mercedes does a poor job! A quick online search proved that this issue is pretty common in MBenz models, there should definitely be a recall. This is inconvenient and appropriate actions should be undertaken against this.

Transmission problem. On several occasions while driving, the car has lurched to a stop because gear changed suddenly from Drive to Park. At other times, the engine revvs and slows when it suddenly switches from Drive to "M1." After stopping, it goes back to "D" on its own. Serious safety issue, as I can get rear ended in traffic, or cause an accident for stopping without notice. I have one photo of the sudden transmission switch to M1 (today). Car has been towed to Mercedes service department; no other inspection yet. No warning lamps. Only that it is happening more frequently.

The rear automatic parking brakes sometimes do not release after driving in the rain or through puddles. This happens after the car is parked for a few hours. So far, the brakes have broken free after applying an extra amount of gas. Then, a loud bang is heard when the brakes let go. This concerns me because what if this happens in a tight parking spot, with cars in front and in back? With the sudden release of the brakes, the car may lurch into either of the cars. I have complained to the dealer twice. The first time they couldn't find a problem. The second time, they took 2 days to duplicate the problem after I told them that wet brakes may be the cause. They then told me the problem is normal, all their cars do it. Their service order does not reflect what they told me.

Transmission violently engage in reverse: so far I have only experienced this (twice) during cold-starts. Started the engine, shift car in to reverse gear, disengage parking break. In normal situation, the car would reverse slowly without applying throttle. In the two times I experinced the problem, the car would still be idle, even after gently applying throttle. After about 5 seconds or so, the car would violently jerk and the transmission finally engaged in reverse. The local mb service center was not able to diagnose the issue. Some gla owners also experinced the same issue, which can be found in this discussion: http://www.glaowners.com/forum/engine-technical-discussion/8297-transmission-woes.html here is the video that illustrates my experience, from another gla owner: https://youtu.be/gln7kpgxyb4
