•Jan 2025, while the car owner was driving her GLC300, a warning light came on, the car shook and then shut down. AAA tow truck suggested Green’s Garage as an approved nearby repair shop. Car was towed there and repaired for approximately $450.00. •[XXX], late afternoon, the same problem arose but the car did not shut down. The car owner drove the car home and the car was dropped off at Green's Garage (GG) on the morning of May 27. Late that afternoon, GG called us to tell us the problem is not related to the January repair…Even though the symptoms were exactly the same as January with the exception of the car not shutting down. GG later stated the new problem is related to the spark plugs and that the cost to repair would be about $450.00. We agreed. •The next day (Wednesday) late in the afternoon GG called us to tell us that they found an additional problem. One of the fuel injectors was leaking. To fix the fuel injector plus the spark plugs would cost about $1,300.00. We agreed. •The car owner picked up the car late Thursday afternoon. Nothing was fixed, the engine warning light immediately came back on and the engine shook, so we have formally disputed the $1,300.00 credit card charge with our bank. [XXX] took the car on June 4 at 9:00 AM to Mercedes of Coral Gables for a pre-arranged $360.00 diagnosis. On June 5 we were informed that the engine and transmission mounts collapsed for a repair charge of $2,518.00. Also, the cylinder head valve seats are leaking and need replacing for a charge of $11,757.00. Total $14,275.00. Mercedes Benz should pay for this. Our car is a 2020 model with only 63,000 miles, but the problems started at less than 60,000 miles. We have read that this problem with this engine has existed since 2024 or earlier and that Mercedes Benz refuses to acknowledge the situation or pay for the repairs. It is dangerous to drive this car. Mercedes should be held responsible for all repairs and and accidents caused by this malfunction. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION

Some M264 Engines are predisposition to premature cylinder head failure, this issue can cause significant misfire issues. It also leads to a costly repair. We experienced issues with a P219D code , we had the coils and plugs replaced on a 2020 GLC 300 with 38.5 k miles. We assumed that this issues with a misfire and check engine light were corrected. My wife was turning onto [XXX] in Pascagoula MS last week, the car misfired and stalled with cars and semi trucks rapidly approaching, several cars had to slam on breaks and this issues almost caused a significant wreck. She had to pull over to gain her composure, the car would not over above 2k RPMs. I showed up and was able to to restart the car , I immediately drove it back to the repair shop. The shop bore scoped the #2 cylinder, the valve seating is significantly damaged, thus causing a significant loss of engine power / misfire in cylinder 2. I reached out to Mercedes Benz USA and was advised to take the GLC300 to the dealer that sold us the car. At present the is being evaluated by the MB dealer. MB USA is well aware of issues regarding cylinder head failure. There is actually a low mileage GLC 300 at MB of Mobile with the same problem as our MB. They have sent out service bulletins to every MB Dealership in the US regarding this issue. Likewise they have extended the warranty on several MB models that share the same engine that are mounted for front wheel drive cars, M260 engine. The M264 is an identical engine that is mounted for rear wheel dive vehicles. It is beyond obvious that a significant loss of engine power poses a threat to the driver/occupants and other vehicles/occupants on the road. MB USA is well aware of this issue with their engines. Not only do they have a service bulletin regarding this matter , they have repair protocols which include a cylinder head replacement. This is a consumer and safety issue that needs to be corrected on applicable GLC 300 models. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMAT

The check engine light illuminated, I took the car to the dealer I bought. They said the cylinder head on the engine needs to be replaced, when I check the internet it seems it is a known issue for Mercedes X253 but there is not a recall program. I bought the car from the dealer, and put on 5k miles in a year.
