Open-data reference.
NHTSA Complaint about SERVICE BRAKES, AIR:ANTILOCK:WHEEL SPEED SENSOR filed March 15, 2022
NHTSA complaint #1801672 (ODI reference 11456844) concerns a 2011 MERCEDES-BENZ R350 and was filed on March 15, 2022. The owner reports the failure occurred on March 15, 2022. The vehicle had 80,200 miles on the odometer at the time of the incident. The report was geocoded to Virginia based on the filer's self-reported location. The affected component is categorized as service brakes, air:antilock:wheel speed sensor, one of NHTSA's standardized taxonomy codes used to group defect patterns across make, model, and year.
The filer flagged the following severity indicators: crash: no, fire: no, injuries: 0, fatalities: 0. No crash, fire, or fatality was associated with this report, which places it in the early-warning stream rather than the priority-review stream. Because a VIN was supplied, this complaint is tied to a specific vehicle and not just a model-year cohort.
Individual complaints are consumer-submitted and unverified by NHTSA engineers — the agency's role at this stage is to collect, index, and make them searchable. What matters for federal action is the pattern: when many owners of the same MERCEDES-BENZ R350 cohort independently describe similar service brakes, air:antilock:wheel speed sensor failures, defect investigators have grounds to open a PE and request manufacturer data. Related filings for the same vehicle and component appear below, and the detail page for the full 2011 MERCEDES-BENZ R350 shows the complete component-level complaint distribution alongside any active investigations or recalls.
Complaint Description
The contact owns a 2011 Mercedes-Benz R350. The vehicle had previously had the wheel speed sensors replaced eight times since September 2016. The contact stated that while driving at 55 MPH, the ABS inadvertently engaged, causing the front end of the vehicle to dip while the brake pedal was depressed.

The vehicle remained with the mechanic, awaiting diagnostic testing. The vehicle was not repaired. The manufacturer was made aware of the failure but provided no assistance. The failure mileage was approximately 80,200. Consumer's complaint is a result of several measures but mainly to the continued wheel speed sensor failures which account to a total of eight (8) newly inst
