What owners report

Owners of the 2022 GLC 300 most often describe two distinct patterns: a steering wheel shake that appears after hitting bumps or road seams at highway speeds, and fuel-system problems tied to the fuel pump recall campaign, including loss of power while driving. Many fuel-system complaints were filed by owners who could not get the recall repair completed because parts were unavailable, and some describe power loss or stalling that recurred after the pump work was done. Electrical complaints form a third cluster, covering warnings, cameras, sunroof and tailgate behavior. Most reports arrive at relatively low mileage.

  1. Fuel system

    Fuel pump recall delay and loss of power

    • 13 complaints (21%)
    • typically at 1.9 yrs old
    • 1 mention a crash, fire or injury
    • filed 2023–2026

    Many owners report receiving notice of the fuel pump recall but being told the parts were not yet available, with the repair delayed for months. Others describe the car losing power or stalling while driving, in some cases after the pump had been replaced, and a few mention repeated dealer visits without a confirmed cause. Reported across a wide mileage range in the sample, from low-mileage cars to vehicles past 50,000 miles.

    Recall 23V445000

    What to check: Ask for documentation that recall 23V445000 was completed and with which parts, and whether any loss-of-power complaint was diagnosed afterward.

    2 excerpts from owner complaints in NHTSA records

    “Safety was at risk when the gears switched to neutral while I was driving in car with my children. A recall was completed when bought car was not aware of fuel pumps recall issue. Says completed repair but the car is still having issues and was sold to me without telling me about the recall. First appeared about a week ago. Making a ticking noise, losing power when accelerating.”

    NHTSA complaint #11633770, filed 2025-01

    “vehicle was recalled for replacement of fuel pump. NHTSA Recall ID 23V445. Mercedes Benz and authorized dealer are unable to repair car at this time. There is a danger of the car losing power and a risk of crash or injury.”

    NHTSA complaint #11540317, filed 2023-08
  2. Steering

    Steering wheel shake over bumps at highway speed

    • 12 complaints (20%)
    • median 5,742 mi at 0.9 yrs old (1 states mileage, few)
    • 1 mention a crash, fire or injury
    • filed 2021–2025

    Owners describe the steering wheel vibrating or shaking sharply after the front wheels hit a bump, pothole, manhole cover or road seam, typically above roughly 45 to 55 mph. Several say the vibration lasts several seconds and makes the car feel briefly hard to control. Complaints describe dealers unable to duplicate the concern, tire balancing or replacement, and a software update or steering-column bracket replacement that did not end the shaking. Reported from a few thousand miles up to about 20,000 miles, usually at highway speeds over uneven pavement.

    1 related service bulletin

    What to check: Drive the car at 50-70 mph over broken pavement and expansion joints and watch for wheel shake that lingers after the bump. Ask whether any steering software update or steering column work has been done.

    2 excerpts from owner complaints in NHTSA records

    “I purchased my car 2022 Merced-Benz GLC 300 from Park Place Motorscar in Arlington Texas on February 17, 2022, and have issues with the steering wheel shaking when I drive over bumps. I have raised the problem with the dealership service department and they have not fixed it after 3 attempts. This is a safety issue and I am very concerned.”

    NHTSA complaint #11464158, filed 2022-05

    “When driving at 40 to 60 MPH and hit shallow pot hole or bump in the road the front wheels violently shake and the steering wheel (electric steering) violently vibrates for 5 to 8 seconds. Dealer checked the vehicle and claims there is nothing wrong with it but did turn off the attention assist setting from sensitive setting claiming it was the cause. The issue still exists but not as violent. I'm concerned of loosing control of the car/my safety. FYI: never experienced this issue with my previous car (same car two years older ,2020 GLC 300). …”

  3. Engine

    Engine misfire, rough running and loss of power

    • 8 complaints (13%)
    • median 35,944 mi at 3.4 yrs old (2 state mileage, few)
    • filed 2023–2026

    Owners describe the check engine light coming on with rough running, misfires and the car refusing to accelerate, sometimes requiring a restart to regain power. Complaints mention dealers replacing spark plugs and coils, flushing the transmission, or reporting no fault found, and one owner reports a valve seat failure requiring cylinder head replacement. Appears from low mileage up to about 60,000 miles, with several reports of symptoms developing after the warranty period.

    3 related service bulletins

    What to check: Scan for stored and pending fault codes, ask for service history on ignition components, and check whether any engine control unit software campaign was completed.

    2 excerpts from owner complaints in NHTSA records

    “My 2022 Mercedes-Benz GLC 300 has been diagnosed with a valve seat failure. This requires a full cylinder head replacement. I purchased this vehicle brand new and have driven it with care, putting approximately 60,000 mostly highway miles on it. Throughout my ownership, I have exclusively used the service at an authorized Mercedes-Benz dealership. Despite my efforts to maintain this vehicle properly, the vehicle began exhibiting misfire issues just outside of the warranty period. …”

    NHTSA complaint #11667722, filed 2025-06

    “Vehicle loses power, my vehicle stop on the highway going 55 miles per hour, I came very close to being rear ended. My vehicle consumes excessive fuel, the vehicle quicks back upon acceleration. This causes a great concern as I used my vehicle for work. I attempted to have the dealer resolve this and I was told that there was nothing they could do. However, this faulty performance might cause a traffic accident and I could also involve the life of myself or another individual in the vicinity of my vehicle. …”

    NHTSA complaint #11540870, filed 2023-08
  4. Electrical system

    Electrical glitches and sudden shutdowns

    • 19 complaints (31%)
    • median 10,000 mi at 1.9 yrs old (5 state mileage, few)
    • 3 mention a crash, fire or injury
    • filed 2022–2026

    Complaints describe intermittent electrical behavior: windows and the sunroof opening on their own, the radio turning on with the car off, camera or infotainment failures, clusters of warning messages, and in a few cases all power shutting off while driving. Owners report software updates or module work at the dealer, sometimes with the problem returning. Reported from under 1,000 miles into the tens of thousands, with no single mileage pattern.

    3 related service bulletins

    What to check: Test every camera, window, sunroof and tailgate function, and ask whether infotainment or control-unit software updates have been applied.

    2 excerpts from owner complaints in NHTSA records

    “The rearview camera on my vehicle intermittently fails to function for unknown reasons, and the problem has recently become more frequent. For example, it may work normally when I first start the car in the morning and back out of my parking spot, but later the same day—such as when I arrive at work—the camera stops working completely. The display stays black and does not recover even after shifting between gears or restarting the system. After parking and locking the car for a while, the camera may start working again without any clear reason. …”

    NHTSA complaint #11698047, filed 2025-11

    “While driving down a busy neighborhood street 2 lanes with cars on both sides making it a 1 lane road pulled over to the side a little to let cars pass. All of a sudden ALL electrical and engine stopped and turned off. Only thing that was powered was instrument cluster with multiple warnings like SRS Malfunction, Steering Malfunction, SOS Inoperative, Parking Brake and more. We believe the car had also shifted to park on its own. No power to anything not even hazard lights. Nothing electrical had any sort of power. …”

    NHTSA complaint #11748161, filed 2026-07

Buying note. Check that recall 23V445000 was completed with the correct parts and confirm there are no other open recalls; then test-drive at highway speed over rough pavement to check for steering shake. A pre-purchase scan for engine and electrical fault codes is worth the cost on this model year.

NHTSA complaint #11731548, filed 2026-04

Steering: “I was driving home on a 4 Lane Expressway on a Saturday afternoon, it was mildly raining with the roads a little wet. I suddenly lost control of the car and could not control the steering wheel, the car ended up hydroplaning and I lost control it ping-ponged across four expressway lanes back-and-forth about 20 to 25 times with zero control of the steering wheel, barely missing the medians and other cars.

NHTSA complaint #11696510, filed 2025-10

Electrical system: “My vehicle got stuck on a EPB(electronic parking brake) and I was unable to disengage it. I tried a few things and none worked.

My car has been at Mercedes for 5 days now and they gave me a response saying that they are having a hard time trying to disengage the EPB. …”

NHTSA complaint #11742050, filed 2026-06

Engine: “The car randomly shows an empty tank of gas at the start of the day, when there was a half tank of gas remaining. I filled the gas, but the car did not register any fuel-up and kept showing empty. I took it to the dealer for repair and the fuel tank sensor was replaced under warranty a month ago. Now, this week the same issue reappeared. The car began showing no gas in the tank on a random morning last week and remained driveable for a couple of days. The gas levels reappeared corrected on day #3. …”
