POWER TRAIN
Rear differential failed at 55,000 miles. Mercedes-Benz of Lafayette IN last had possession of the part. In a high-speed turn, this could result in loss of control of the vehicle. The differential was replaced at the owner's expense, and the failed part was left with the dealership. I am aware of numerous reports of premature rear differential failure in this model (after the fact). There was an occasional thunking noise during turns that the driver (my son) did not think anything of. The vehicle has been meticulously maintained. Within the week the vehicle was serviced and the rear differential needed to be replaced. No warning lights were present.

POWER TRAIN
The vehicle change's gears and automatically switch to neutral while driving. I almost had a major accident on the interstate. This happened several times and the last time it happened was on September 23rd. The first time the incident happened I was told that it was a sensor in the car and was charged $700 and 4 days later it happened again. I took the car in again and now I am being charged for a new valve body in the transmission and a battery replaced aux battery. In my opinion that is a default not a maintenance issue and I should not have to pay for this, and Mercedes should have a recall on this because it can cause a very serious accident.

VISIBILITY:SUN/MOON ROOF ASSEMBLY
The contact owns a 2016 Mercedes-Benz GLA250. The contact stated that the sunroof panel had detached, allowing wind and debris to enter the vehicle.

The unknown dealer pushed the sunroof panel back into position; however, the failure recurred due to the wind. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 47,000.

My Mercedes-Benz, 2016GLA 250 vehicle. The automatic transmission shifts into neutral while driving. It’s happened on multiple occasions and it’s very scary. This is a dangerous safety issue! I’ve seen it’s been recalled/addressed for other GLA250 model years, but not for 2016 year models. Please bring to MB USA attention. Thank you very much for your assistance!

UNKNOWN OR OTHER, VEHICLE SPEED CONTROL, ENGINE
Dec 2- filled car with gas, check engine light illuminated and then three more errors displayed on the dash. See list below. Errors displayed on dash… 1-INOPERATIVE -- SEE OPERATOR’S MANUAL (Shows ABS and skid icons) 2-COLLISION PREVENTION ASSIST PLUS INOPERATIVE 3-ABS CURRENTLY UNAVAILABLE – SEE OWNER’S MANUAL 4-CHECK ENGINE LIGHT ON Later that same day, Dec 2, we started the car but could not get it into Reverse. We shut the car off, started it again, and were able to shift into reverse and proceed. Dec 3rd- we attempted to remove and reapply the gas cap to see if engine light would go off and error messages would resolve. It did not. We did not drive the car that day. Dec 4 and Dec 5th- all above error warnings display all day. Dec 6th- We scheduled a service appt at Mercedes in Sarasota, FL for the 1st avail appt Dec 10th. We were told in writing the car could be driven until the appt and no additional issues should arise. Dec 7th- new error code appears… 5-REVERSING NOT POSSIBLE - SERVICE REQUIRED. This is when the car put our lives at risk. While driving, the car shifted itself into Nuetral. We were unable to get the car into gear as it continued to roll. Having no control of acceleration, we guided the car to the right to allow traffic to pass. We put the car in park, shut down the vehicle, wait 15 minutes, and restart. We were then able to drive forward, but WHILE MOVING, “REVERSING NOT POSSIBLE” reappeared, the car shifted itself into neutral again. We were unable to shift to DRIVE. We shut the car car down again, started it, shifted to drive, but it went into DRIVE 2 only. We drove in 2nd gear until we were safe off the road and home. We towed the car (12/7 evening) to Mercedes in Sarasota FL. Dec 8th: Service dept finds the two front wheel speed sensors failed and caused a chain reaction sequence of events. They referred to the problem as ‘minor’. This is a serious design flaw. We are lucky not to have been hurt or killed

P052E-71 The valve for crankcase ventilation has a malfunction. The actuator is blocked. Was initially intermittent but seems to be getting worse. Dealer quoted ~2k to repair, which seems astronomical for a PCV valve. Common problem with these engines.

UNKNOWN OR OTHER
Faulty Panoramic Sunroof. I took the car to the dealer service to have the sunroof checked since it won't close all the way that the guide rails jammed and faulty. It is too expensive to get it fixed after taking to Mercedes. I haven't owned the vehicle very long and only used the sunroof maybe once or twice and it stopped working. This should be a recall and I shouldn't have to pay to fix it. I am worried that it might come off while driving, for now it is sealed with wrap.

My car puts itself into neutral while driving and while stopped. This has happened 4 times now. The dealer claims they aren’t familiar with this issue. My safety and the safety of others driving around me are in danger. Today, I was changing lanes on the feeder road, and my car locked up into neutral and wouldn’t let me drive it. The error message says “Do not shift gears. Visit dealer”. This car has been in no accidents and hasn’t had any work done other than routine work.

FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING, LANE DEPARTURE: BLIND SPOT DETECTION, LANE DEPARTURE: WARNING
Lane departure warning, blind spot assist and emergency braking stopped working all at one in May 2021. Left it for service at the local dealership and they changed one of the 'modules' only for the problem to reoccur one week after picking it up, this time with the engine stalling and having to pull over from the middle lane of the highway. Car has been with Mercedes benz Danbury, CT dealer since July 12th 2021 and they are still unsure what is happening. Mercedes Benz seems aware of the risks involved with a stalled engine and provided me with a loaner that I have been driving since that day. They escalated the issue with the manufacturer in Germany.
