Most recent owner complaints, unedited.
See attached document for complaint
Cowl vent grille openings allowed normal environmental debris to accumulate, plug drainage and divert water onto electrical components and potentially result in a fire if not addressed. Some of the debris passes through into the hvac system and cannot be cleaned without dealer removal/repair of the hvac motor, which costs the customer more than $500 in repairs and disincentivizes mitigation. Furthermore, Mercedes is aware of the problem, has not issued a customer satisfaction recall, and instead, is charging customers more than $1,000 to install a plastic protective shield to prevent accumulation of debris, clogged water management, and risk of fire.
The Gas Door did not open in order to pump gasoline. There is no mechanical device for the driver, passenger, owner of the vehicle to manually open the gas door from the inside. There was no electronic warning within the Mercedes Benz to alert driver about malfunction of gas door not working. Driver took vehicle to local Firestone mechanic who said the "gas door actuator" needed to be replaced. Accordingly, vehicle with the remaining gasoline was taken to local Mercedes Dealer who after the vehicle being looked at, "confirmed gas door to not opening due to internal mechanical fault" and replaced with new gas door actuator at a cost of $820.28. Vehicle owner mentioned to service rep, that he lives from parents about 150 miles away and had the vehicle owner stopped at gas station in between, the vehicle owner would have been stranded without any access to a dealer to fix this critical safety issue. Vehicle owner then advised service rep this issue should have been elevated as critical safety recall issue and that a complaint would be filed with the federal safety agency. Any vehicle owner, their family if being transported in a deserted place hoping to go to the next gas station for pumping gas would have faced a severe danger to their self and their families. Vehicle owner has sent a detailed letter to Mercedes Benz corporate office in USA detailing the incident and a copy of the letter will be attached as an attachment if it is permitted in this complaint. Requesting a recall of this issue with an order for reimbursement of service charges paid by vehicle owners to fix this "malfunction of gas door". There are multiple complaints to this effect on various message boards regarding the occurrences of "gas door not opening". This also needs to be looked at.
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.
I am reporting a potential safety and mechanical defect involving the cylinder head in the Mercedes-Benz GLA 250. Many owners, including myself, have experienced premature cylinder head failure, often without warning, leading to loss of power, engine misfires, rough idling, and in some cases, sudden engine shutdown while driving. This issue appears to be widespread among GLA models equipped with the M260/M270 engine, often occurring well before 100,000 miles. It raises serious concerns about the design, durability, and safety of the engine’s top-end components. Given the frequency and severity of this failure — and the high cost of repairs — I believe this warrants an official investigation and potential manufacturer recall. I urge the federal safety agency to review similar complaints and initiate a formal inquiry into Mercedes-Benz’s awareness and handling of this defect. Thank you for your attention to this matter.
Twice now, my husband is putting groceries in the back of the vehicle and the top closes on him and this last time, hit him hard in the head. This is a safety issue, what can we do??
My vehicle has two separate tire inflation placards. There is a placard inside the drivers door recommending 43 PSI (cold) all tires, and another placard inside the fuel door recommending 38 PSI front and 34 PSI rear (cold). Two different tire service centers have confirmed that my tires are wearing out prematurely because of overinflation. My telephone calls to Mercedes USA have been handled poorly because their representatives are poorly training and do not understand the nature of my issue.
Engine misfired in operation requiring an emergency stop while on a mountain road. Severe check engine light turned on (Mercedes has a two stage check engine light). Vehicle was parked for 20 minutes and battery was disconnected. This appeared to fix the issue. Vehicle was brought to dealer. Dealer stated the cylinder head for early 2021 GLA 250 engines had a casting flaw that result in hot gases escaping and damaging engine. Engine and turbo rebuilt under warranty at 17000 miles.
The entire circuit board was short circuited immobilizing the car in the middle of the highway. It was determined that the condensation of the air conditioning was unable to drain due to the drainage tubing being clogged with insects, causing water to back up and short circuited the electrical system.
