A complaint is an unverified account by the person who filed it, not a finding of fault. One complaint is one ODI number, which is how NHTSA counts them.

A recall is the manufacturer conceding a defect, and the repair is free. Whether one covers your particular car is a question only its VIN can answer, because a campaign covers a production range rather than a model year.

Red marks a system with a recall campaign against it. One complaint can name several systems, so these add up to more than 10.

When the complaints arrived

By the year NHTSA received them

By the year NHTSA received them, which is not the year the failures happened. They peaked in 2026 at 7.

This is the year the complaint was filed, not the year the failure happened. The range runs from 2025 to 2026, the last of them a part year, which is why its column is drawn faint.

Crash test ratings

NHTSA New Car Assessment Program

NHTSA has not crash tested the 2025 Mercedes-Benz GLC 300 4Matic. Its New Car Assessment Program tests a selection of each year's vehicles and does not reach motorcycles, heavy trucks, motorhomes or most low-volume models, so an absence here says nothing about how the vehicle would perform. It is not a low score.

What owners have reported about this vehicle is below, and it is a different question: a crash test measures what happens to the people inside in a controlled impact, while a complaint records what broke during ordinary use.

In the event of a crash, insufficient impact protection can increase the risk of injury.

License Plate: 9RHN710 Dealer Servicing Vehicle: Mercedes-Benz of Stevens Creek (AutoNation), San Jose, California The vehicle has repeatedly experienced unexpected and unprovoked braking events, including situations where the automatic braking system engages despite there being no vehicles, pedestrians, or visible obstructions present.

NHTSA complaint 11723692, quoted in part. Filed by an owner and not verified by NHTSA or by us.

STRUCTURE:BODY

1 injured

The liftgate on this car is faulty. There are hundreds of reports online that I found when it happened to me, which has been several times now. The liftgate has a sensor that is activated by your foot, but when you are inside the hatch it will trigger and close on you. There is no sensor to stop it from falling and it traps you inside and has hit me on the head, bruised my shoulders and back and I have fallen from being hit by it. I have reported it to Mercedes several times and asked them to at least cover the sensor and they say it's not possible. This is dangerous and it's going to seriously injure or kill somebody younger or more feeble.

NHTSA complaint 11761794. Filed by an owner and not verified by NHTSA or by us.

POWER TRAIN
Vehicle experiences a severe, abrupt jerk/jolt during deceleration around the 5th-to-4th gear downshift. The issue occurs consistently when slowing down. Dealership verified the condition on Repair Order #1906625 and confirmed a transmission flaw. Dealer stated software is required from the manufacturer with no ETA for release. The abrupt deceleration creates unexpected cabin jolting during normal traffic slowing.

NHTSA complaint 11755359. Filed by an owner and not verified by NHTSA or by us.

ELECTRICAL SYSTEM
The instrument cluster display went dark and has not been able to display any information such as speed in miles per hour, fuel gauge, and other important information needed to maintain safe driving.

NHTSA complaint 11742067. Filed by an owner and not verified by NHTSA or by us.

ELECTRICAL SYSTEM
All of the screens in the car failed to start. They remained black while the car was running. Turning the car off did nothing. Drove to a parking lot, turned the car off, got out, locked the car, waited 5 minutes and it still didn't come back. Had to do a reboot by holding the system power button for 10 seconds. This has occurred 3x in 9,200 miles.

Every Mercedes-Benz on this site — 227 vehicles.

If this is your car and a dealer keeps failing to fix it, your state's lemon law may require the manufacturer to replace it or buy it back. How many repair attempts it takes, and how long you have to file, is set by the state you bought in and by nothing on this page.

Where these numbers come from

A complaint is one owner's account and has not been verified by NHTSA or by us. A vehicle with more complaints is not necessarily worse: models that sold in larger numbers collect more of them. How this is counted.
