2014 Mercedes-Benz GL-Class owner complaints

The lane-keeping assist only intermittently works. On occasion it will alert and take corrective action, but even on sunny days with clearly demarcated lanes, it often does nothing. In researching this issue, there are several other owners who have experienced this and have said the Mercedes service has unofficially acknowledged there is a batch of VIN numbers which have faulty sensors. We purchased this car because of the safety features and Mercedes needs to do something to rectify this in order to keep its customers safe.

I had just arrived home. The car was off and I was parked in my garage. I opened the door but it didn't open all the way to the first hinge. My hand was in the door as it slowly started to close. The door caught slightly and the soft close feature activated. My thumb was caught in the door and was crushed as the door sealed completely closed with the soft close feature. I was unable to open the door during this time. I was yanking on the door handle trying to open the door to free my thumb but the door would not open until the soft close was complete. As a result my thumb was crushed. I believe that this a design fault with the vehicle. The fact that there was no sensor to detect something in the door as well as not being able to open the door at any point during the self close process pr

Consistent mildew foul odor comes from the air condition.

To the best of my knowledge - certain high end gl model have optional easy third row entry. The second row in such models folds with a touch of a button. However when fully deployed - the second row seat's head rest in such models prevent proper installation of kid's carseat ' such that the upper part of the carseat is projected forward. I am 6 feet and can easily put the whole of my forarm behind my kid's carseat after installation. The result is ' a very uncomfortable forward positioning of the kid's carseat. My kid has reported neck sprain multiple times. The issue does not resolve with using a booster only (without backrest) or with car's headrest not deployed ' as in all situations the car's head rest still pushes my kid's head forward. I believe that it's a potential safety issue

There is a recall on some of the make & models of my truck with different years but, my truck has been having the same issue & I believe that myself & my family may be at risk. The recall states that if the oil level in the ACS reservoir is below the minimum level, the oil may foam & leak out of the vent holes in the reservoir cap. The leaking of oil in the presence of ignition source can increase the risk of fire. I have been having to add two quarts of oil to my car every month for almost a year & there has been no oil in my driveway at all. The oil is going somewhere & I would like for my truck to be put on the recall list & have this issue addressed. My brakes also seem to have an unexplainable issue. Most times they're perfect but, sometimes they vibrate very hard when stopping no mat

The car ran out of brake fluid - there was an indicator and when taken to service we were told the reservoir was empty. What is alarming is that the car is serviced very frequently and one set of brakes was recently replaced (about 6 months). Moreover the dealer stated there was no leak. They stated that they do not replenish the brake fluid when replacing pads, in essence, because the fluid system is so fragile and they are afraid they will do more harm than good. It seems like a straightforward proposition that if the brakes are checked and pads replaced frequently, and there is no leak, there should be no possible way for the fluid to go empty absent a defect in the car (excess fluid consumption for some reason besides a leak) or faulty maintenance procedures. I believe the practic

I recently purchased my Mercedes from Auto Boutique in Pearland, Texas (713) 352-0777. 1.The vehicle's air suspension system is constantly grinding, and moving/adjusting while being driven. It feels like the vehicles fame is off balance. 2. The back camera system does not work unless the radio is turned on; which is very alarming not to mention dangerous. 3. All the tires are registering improper inflation errors even though no air has been added or removed. I took the vehicle back to the place of origin; but they are not Mercedes Certified to address the issues. I am terrified to drive the vehicle, and it stays parked in the garage

' '['? /The right front headlight was replaced (after receiving a headlight warning) approximately about a year after the warranty expired. The dealership claimed this was due to moisture in the headlight. In August 2021, the left front headlight showed to be having issues with the same error message. Upon further inspection, the mechanic noticed that it was not moisture in the headlight that was causing the short, but an oily substance. The mechanic believes that there might be a bushing in the headlight that might be melting/breaking down due to the heat. This is causing the headlight to short and require a $3500 replacement
