Five years of fuel
$16,770–$21,180U.S. average; Ohio $15,800–$19,960 at local prices; every version of this model year; fuel only, not other costs of owning it; 15,000 miles a year, at EIA fuel prices for the week of Oct 12, 2026
NHTSA's VIN data lists these trims for the 2022 GLC-Class. A trim's engine and numbers are shown as its own only where EPA names versions after the trim and no other version could be it; "seen with" means a source shows that engine on the trim, not that it was the only one. Recalls and complaints cover the whole model year: whether a recall applies to a car depends on its VIN, on NHTSA's recall lookup.
Owners have filed 64 complaints with NHTSA about the 2022 GLC-Class. These are unverified owner reports, counted by the part of the car they name; one complaint can name several parts. Counts aren't adjusted for how many were sold, so they don't show how reliable a car is.

What the columns count
Complaints: complaints that name that part. One complaint can name several parts, so the rows overlap and don't add up to the total.
Crashes and Fires: complaints that report one. Two owners can file about the same event, and NHTSA doesn't link them, so these count reports, not events.
Injuries: the number of people the complaints say were injured.
None of these columns shows that a part caused a crash, fire or injury: they're what owners reported, unverified.
Complaints by model year
Newer years have had less time to collect complaints, and counts aren't adjusted for sales, so a shorter bar doesn't mean a more reliable year.
NHTSA lists 2 recall campaigns for the 2022 GLC-Class over its history. Campaigns are matched by model and year, so each one may apply to a given car, and its repair may already be done: check a VIN on NHTSA's recall lookup for the open recalls on that exact car.
Exterior lighting: headlights
NHTSA campaign 24V070000 · reported Feb 2, 2024 · 15,502 vehicles potentially affected across the whole campaign
Remedy: Dealers will inspect the headlight adjustment and correct it if necessary, free of charge. Owner notification letters were mailed February 23, 2024. Owners may contact MBUSA customer service at 1-800-367-6372.
Mercedes-Benz USA, LLC (MBUSA) is recalling certain 2019-2022 GLC 300, 2020 GLC 350e, and 2020-2022 AMG GLC 43 vehicles. The headlights may be incorrectly adjusted too high and create a glare for oncoming traffic. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 108, "Lamps, Reflective Devices, and Associated Equipment."
Risk: Incorrectly aimed headlights can reduce the visibility of oncoming traffic, increasing the risk of a crash.
NHTSA campaign 23V445000 · reported Jun 26, 2023 · 143,551 vehicles potentially affected across the whole campaign
Remedy: Dealers will replace the fuel pump, free of charge. Owner notification letters were mailed on June 14, 2024. Owners may contact MBUSA customer service at 1-800-367-6372. MBUSA's number for this recall is 2023070012.
Mercedes-Benz USA, LLC (MBUSA) is recalling certain 2021-2023 C-Class, E-Class, S-Class, CLS, SL, GT, GLC, GLE, GLS, and G-Class vehicles. Please refer to MBUSA's recall report for specific vehicle details. The fuel pump may shutdown, which can result in a loss of drive power.
Risk: A loss of drive power can increase the risk of a crash.
