Key facts
- Campaign: NHTSA 26V481000 (Part 573 filed July 24, 2026; VINs searchable at NHTSA.gov July 31, 2026).
- US units: 310,667. Mercedes estimates 100% of the population carries the defect.
- Models in scope: A-Class (2019-2022), CLA (2020-2021), C-Class (2022-2023), CLE (2024), GLA (2021-2025), GLB (2020-2026), GLC (2023-2024).
- The GLE and GLS are NOT in this recall.
- Defect: driver's-door-lock microswitch (supplier Kiekert AG) corrodes under sustained heat and humidity and can fail to detect the door opening, defeating automatic parking-brake engagement.
- Risk: a parked, unattended vehicle can roll away. Service brakes are unaffected; the driver can still set the parking brake manually.
- Harm reported: 176 US field cases (all comfort-function only, e.g. radio/lights staying on), Mar 2021-Jun 2026. Mercedes reports zero US rollaway cases and no crashes, fires, injuries or deaths.
- Remedy: dealers replace the driver-door lock free; production was corrected May 20, 2026. Owner letters expected by September 18, 2026. No "do not drive" or "park outside" advisory issued.
Are the GLE or GLS SUVs in this recall?
No. Recall 26V481000 covers the compact Mercedes SUVs — the GLA, GLB and GLC — plus the A-Class, CLA, C-Class and CLE cars. The larger GLE and GLS are not part of this campaign. Buyers and search results that pair "Mercedes," "rollaway" and "GLE/GLS" are mixing up model lines; verify any specific car against the affected-models table below and the official VIN lookup.
Affected models and model years
| Mercedes line | Platform | Model years in recall | Body style | Example trims |
|---|---|---|---|---|
| A-Class | 177 | 2019-2022 | Sedan (car) | A 220, A 220 4MATIC, AMG A35 |
| CLA | 118 | 2020-2021 | Coupe/sedan (car) | CLA 250, CLA 250 4MATIC, AMG CLA35/CLA45 |
| C-Class | 206 | 2022-2023 | Sedan (car) | C 300, C 300 4MATIC, AMG C43 4MATIC |
| CLE | 236 | 2024 | Coupe/Cabriolet (car) | CLE 300 4MATIC, CLE 450 4MATIC, AMG CLE53 |
| GLA | 247 | 2021-2025 | Compact SUV | GLA 250, GLA 250 4MATIC, AMG GLA35/GLA45 |
| GLB | 247 | 2020-2026 | Compact SUV | GLB 250, GLB 250 4MATIC, AMG GLB35 |
| GLC | 254 | 2023-2024 | Compact SUV | GLC 300, GLC 300 4MATIC, GLC 300 Coupe, AMG GLC43 |
The Part 573 summary line reads "MY20-26 GLA/GLB," but the itemized trim list shows GLA units starting in 2021; treat GLA as 2021-2025 unless MBUSA corrects it.
What does the defect actually do — do the brakes fail while driving?
No — the brakes do not fail while driving. A microswitch inside the driver's-door lock has a housing that can let moisture in; under sustained high heat and humidity the switch corrodes and may stop detecting that the driver's door has opened. Mercedes's Auto-Park feature engages the electronic parking brake automatically when the driver exits, and that action is tied to the door-open signal. If the switch fails, the parking brake may not auto-engage, so a parked and unattended vehicle can roll away. The service brakes, the door latch and manual parking-brake operation all still work.
The warning sign an owner would notice is a comfort-function glitch driven by the same signal: the radio or interior lights stay on after the driver exits, because the car does not register that the door opened.
Did NHTSA owner complaints predict this recall?
Only weakly. This is the honest core of the data story. Mercedes's own filing reports zero US rollaway cases and 176 field reports — all comfort-function symptoms, not rollaways. A scan of NHTSA's public owner-complaint database for the in-scope model-years surfaced roughly 378 complaints, but only one cleanly matched the recall defect: a 2023 C-Class (C 300) that, on February 17, 2024, rolled down a slight grade into a neighbor's building while parked and unoccupied — about 17 months before the July 2026 recall. Two other complaints mentioned rolling-away language but describe different faults.
So the public complaint feed did not show a rising pile-up of rollaway reports. The genuine early precursor was the comfort-function symptom (radio/lights staying on), which Mercedes logged internally 176 times before treating it as a safety issue. For a used buyer, the lesson is that recall-quality signals often live in the manufacturer's data long before the public complaint file catches up — which is why screening a specific VIN matters more than reading the aggregate complaint count.
By the numbers
- 310,667 — US vehicles recalled under 26V481000.
- ~100% — share of the recall population Mercedes estimates carries the defect.
- 176 — US field cases reported (all comfort-function; Mar 1, 2021-Jun 9, 2026).
- 0 — US rollaway cases, crashes, injuries or deaths reported by Mercedes.
- ~378 — NHTSA owner complaints across the older in-scope model-years.
- 1 — clean pre-recall parked-rollaway complaint found in that set (2023 C-Class, Feb 17, 2024).
Based on ~378 NHTSA owner-complaint records for the in-scope Mercedes model-years (complaintsByVehicle API) plus the 26V481 Part 573 report, retrieved August 4, 2026. Complaint totals are approximate: NHTSA model buckets can double-count trims, and 2024-2026 GLA/GLB, CLE and some 2024 GLC records returned no results (too new), so newer-year complaints are undercounted.
How to check a used Mercedes for this open recall before buying
Start with the free, authoritative source: enter the VIN at NHTSA.gov/recalls, which shows whether a car has an open recall (26V481 VINs became searchable July 31, 2026), or use Mercedes-Benz's own recall lookup. To confirm whether the door lock was actually replaced, ask a Mercedes dealer to check remedy status by VIN — that is the only way to learn open-vs-fixed status. A paid VIN history report such as Zilocar is a useful third option alongside those: it flags recall presence like NHTSA's tool, and it adds the vehicle-history records — accidents, salvage-auction, odometer, ownership and past sales listings — that a recall lookup alone never shows.
What a VIN check can and can't tell you here
| A VIN history report CAN confirm | It CANNOT confirm |
|---|---|
| Open-recall presence/count (like NHTSA's free tool) | Whether the recall was remedied/fixed |
| Accident & damage records (location, type, severity, airbag deployment) | Per-unit dealer repair or firmware detail |
| Junk/salvage auction records | The legal title-brand classification |
| Odometer/rollback check, theft (NICB) | Whether the car was exposed to the corrosion-triggering climate |
| Ownership history and past/current sales listings (price, mileage, days-on-market) | NHTSA investigations (PE/EA), e.g. the older-Ford probe |
For this rollaway defect specifically, the accident/damage and salvage-auction records are the real value-add: they can reveal whether a specific unit already had a low-speed or unattended-movement impact event that the recall data never captures. Remedy status, investigation tracking and firmware confirmation stay with NHTSA and the dealer.
Before you buy one of these Mercedes, run the VIN through Zilocar to screen for open-recall presence and pull the car's accident and airbag-deployment records, salvage/junk-auction history, odometer check, theft record, ownership timeline, sales-listing history, specs, NHTSA/IIHS ratings and market value — then confirm the recall repair itself with a Mercedes dealer.
How this fits the summer 2026 safety wave
The Mercedes recall landed alongside two other NHTSA actions that buyers often lump together but shouldn't. In late July 2026, Volkswagen recalled 2024-2026 Atlas and Atlas Cross Sport SUVs (recall 91TV, VINs searchable July 28) for a software glitch that can blank the rearview camera; unit counts differ across outlets (~57,851 vs ~79,579) and remain unresolved. On August 3, 2026, NHTSA upgraded a probe into 135,551 older Ford Fiesta, Focus and EcoSport 1.0L vehicles (roughly 2014-2021) to an Engineering Analysis over timing-belt degradation that can starve the oil pump. The Ford item is an investigation, not a recall — a VIN check cannot flag it, and no repair is yet ordered.
