Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“Rear Belt Monitor Fault continues to be an issue. We received this warning light and supposedly had this repaired in October of 2024. The dealership replaced the rear seat belt buckle and reset the codes. This worked for a while but now is happening again. Additionally, we are receiving an airbag warning related to the rear belt monitor. When driving even short distances the warning light appears on screen maybe 5 or 6 times. If a seat belt is disconnected there is no audible warning alert or light to let the driver know that it is not in use. …”

NHTSA complaint #11685749, filed 2025-09, 17,000 miles“The contact's daughter-in-law owns a 2021 Ford Bronco Sport. The contact stated that the message Rear belt monitor fault - Service Required' was displayed on the instrument panel. The vehicle was taken to a local dealer where it was diagnosed that the rear-row seat belt harnesses needed to be replaced. The vehicle was not repaired because the warranty had expired. In addition, the contact stated that the vehicle had an extended warranty; however, the repair was not covered under the warranty. The manufacturer was made aware of the failure. The failure mileage was approximately 44,000.”
NHTSA complaint #11642805, filed 2025-02, 44,000 miles“I received an error message from the car that stated Restraints Indicator Lamp Warning . This issue was for the passenger side seat and made the car turn off the air bag as it couldn't confirm the seat belt was being used even though it was. Ford stated this issue would not be covered as the vehicle only has a 5 year or 60,000 mile safety coverage. After some research on Reddit, it appears this may be a bigger issue that is impacting the Bronco Sport and the Maverick.”
