NHTSA complaint 11766452See attached document for complaint
NHTSA complaint 11758450Cowl 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.
NHTSA complaint 11743847The 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 NHTSA. 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.
NHTSA complaint 11713295When 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.
NHTSA complaint 11677929I 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 NHTSA 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.
NHTSA complaint 11661372Twice 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??
NHTSA complaint 11632215My 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.
NHTSA complaint 11585806Engine 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.
NHTSA complaint 11547873The 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.
NHTSA complaint 11546751I purchased this car approx 3 months after real issues began. My car would have issues idling where it would sometimes turn off at stop lights and require multiple reignition attempts before proceeding. This would also happen when the auto-start feature (anti-idle/gas saving) was engaged (which is the default in the system) and this posed major safety concerns. The unstable idling of the car would result in an initial acceleration after being stopped, shortly followed by the engine dying. There were multiple times I was at an intersection yielding before turning where this happened and it resulted in my being in the path of oncoming traffic without the ability to accelerate until the car restarted. I contacted my local Mercedes dealer who acted like this wasn't a big deal, but it is related to a known issue with a faulty cylinder head. They covered the repair under the manufacturer warranty, but told me to keep driving my car and promised it was safe until they could get the part in (because the didn't have a loaner car to provide). I found this very troubling. In conversations throughout the repair being completed, the dealer admitted that they know the part that was used for the year and model is bad, but they didn't want to do a recall and would wait for issues to come up. This is unacceptable because this absolutely is a safety concern as demonstrated by the example I shared. They should be required to do a full recall to address the safety concerns and I believe not disclosing this information was unfair to me as a consumer who did not have the information I needed to be informed on the reliability of this vehicle prior to purchase.

NHTSA complaint 11467250I was parked in a lot and turned the ignition on and selected "DRIVE" but when I started to pull away the vehicle went backwards instead of forwards (as though "REVERSE" had been selected). I switched back to PARK, then selected DRIVE again and the vehicle once again went backwards. I then turned the engine off altogether and restarted it and this seemed to clear up the problem as now the vehicle went forwards when in DRIVE. No damage, or injuries, but of course very concerning from a safety point of view which is why I am reporting this. Mercedes did check the vehicle out the next day and could not locate any problem.
NHTSA complaint 11464869Car's brake system slammed on in light traffic with no nearby obstacles. Clear night, light traffic, road dry, moderate temperature. If there had been more traffic, or if the road had been slick, high probability of risk. Dealer has been notified, will not be able to pick up vehicle for a day or two. I did not see any warning lights, heard no warning sounds.
